To be honest, Bud has a good impression of this alien group that he has never even met face to face.

At this moment, a low-frequency hum suddenly came from the monitor earphones, and an indicator light on the nearby device also flickered—the main antenna caught the already familiar signal.

Bud subconsciously looked up at the mechanical clock hanging on the opposite wall, and found that the signal appeared nearly an hour earlier than the "routine greeting" these days.

A trace of doubt flashed in his heart, but this did not affect his work at hand—no matter what news the Noi people suddenly sent, as a senior "listener" of the monitoring department, he must ensure that the information is completely and properly Record and report the important summary or major changes to the superior in time.

The recording device has begun to automatically store the original signals captured by the main antenna, and the automatic compilation system connected to the main brain has begun to convert those signals into pictures according to a mature process, and output them to the magic projection in front of Bard. , The printing device next to it also creaked and ran quickly, printing the processed images into paper documents for later transfer and retention between departments.

Bud was doing these tasks skillfully, while listening to the pleasant ringing from the monitor earphones, he glanced at the data spit out by the printer next to him, and unconsciously turned a pen in his hand, but gradually, his face Showing a somewhat astonished expression, the movements of his hands also stopped a little bit.

The signal captured by the main antenna is still continuing-this is not a short routine greeting, the Nuoyi people suddenly sent a lot of messages!

Chapter 1444 A "Great Gift"

In the building of the Magic Energy Technology Research Department, a comprehensive research room is brightly lit, and the large holographic projection in the center of the room is humming, and a large number of images, numbers, and explanatory texts clearly appear in the air above. The magicians and runemasters in white robes gathered around the projection device, concentrating on the changes in the video while discussing in a low voice from time to time, and some technicians held recording boards in their hands and kept wrinkling Write eyebrows and do calculations.

Jenny, the Chief Runemaster of the Empire, stood among these researchers, her long gray hair was pulled up high by her, and the faint scar near her cheek was completely ignored now. She was also paying attention to the holographic projection in front of her, but she was just alone He was frowning and thinking, not participating in any discussions around him.

Rebecca's voice came from the side, interrupting Jenny's contemplation: "Do you see what's wrong?"

"...This is a very complicated system. It is very difficult to understand its basic principles in a short period of time, let alone what is wrong with it." Jenny shook her head gently, her voice was low, "the only one now The good news is that this thing does not seem to be completely incomprehensible... Although the technology used by the Noi is obviously very different from ours, it seems that now, at least with the annotations, we still have a chance to understand its inner mechanism of."

"In other words, their technical level may not be much higher than ours, right? At least in terms of basic theory, we are not much different from the 'alien civilization'." Rebecca nodded, "What about the other device? What about the set they sent over at the beginning?"

"That thing is relatively easy to understand. It seems to analyze the 'background oscillation' in deep space through indirect observation of the magic oscillations of other stars. At the same time, there are a large number of auxiliary observation units to assist in this task. Although the basic principle is still It needs to be analyzed, but if it is just 'construction', it will not be a problem for us," Jenny nodded quickly, "The 'notes' sent by the Nuoyi people are very detailed, which is very helpful for us to understand those blueprints. Helpful and..."

"And?" Rebecca asked subconsciously.

"And these blueprints should have additional reference value for us," Jenny said cautiously, "Although it's hard to say whether these things can be fully believed, at least in terms of solving some specific technical problems... I feel inspired .”

"That's it..." Rebecca looked stunned, and just when she was about to say something more, she heard the door of the research room being pushed open, and someone exclaimed in a low voice: "It's Your Majesty! "His Majesty has come in person!"

Rebecca hurriedly looked up, and saw that tall figure walking towards her at a glance, she immediately smiled and stepped forward: "Your ancestor is here!!"

"I received the news from here," Gawain nodded, reached out and rubbed Rebecca's head, and then saw the blueprints and the blueprints floating around the large holographic projection in the center of the room at a glance. His brows were also slightly frowned, "The Nuoyi people suddenly sent a lot of 'technical information'? What's the specific situation?"

"Like what you saw, they sent a lot of blueprints without warning," Jenny walked up to Gawain, turned around and pointed to the blueprints on the projection They said, "These blueprints belong to two sets of systems, one is a detection device for observing the vibrations of the deep space magic tide, and the other... the notes say it is the technical data of the 'unified mind field'."

"And these materials haven't been sent out yet!" Rebecca followed up and added, "Right now, Sorin's main antenna is still sending data, and the scale of supporting facilities in this 'Mind Unification Field' is larger than we imagined. It’s amazing, judging from the notes and serial numbers on the blueprint, I’m afraid that less than a third of it has been sent up to now…”

"The blueprint of the magic tide detection device and the mind unification field device?! And a full set of blueprints!?" Gawain's eyes widened in an instant. He had suddenly received news that the Nuoyi people had sent a large amount of information without warning. At that time, he guessed whether this "alien civilization" decided to send some basic things over to show sincerity, just like the promotional materials released when selling products, but he never expected that the other party would send a full set of blueprints directly, "They What else happened?"

"So far, there are only information, more and more information." Jenny rubbed her hands a little cautiously, "We can't take the initiative to ask the situation over there, so we can only answer what the other party sends first..."

Gao Wen frowned more and more, and when he looked at those blueprint projections, his gaze became more serious than before——the core technology that can be called "top secret" was packaged before the real cooperation was negotiated. Sending, this has gone far beyond the scope of "expressing sincerity". Looking at this matter from the three views of a human being, the information revealed behind it can only make people feel uneasy, either, this is a huge conspiracy, or , which means that the situation is urgent.

Neither possibility is very flattering.

Of course, Gao Wen is not a Noi, and he does not know any real Noi. He does not rule out that this is a misunderstanding caused by aliens' way of thinking is different from his own, but now he can only use three human Think and deduce the problem from a perspective.

"Can you see anything?" He looked at Rebecca beside him. In terms of technology, this iron-headed girl never disappoints, "How long has it been since the first time I received the information?"

"It's been almost half a day," Rebecca nodded, and then pulled Gawain to an equipment table not far from the central holographic projection, picked up the printed drawings on the table, and handed them to Gawain. "Look at this set first. This is their 'Magic Tide Observation Device'. The notes say that this thing can indirectly calculate the background oscillations in deep space by observing the magic fluctuations released by the stars. Jenny initially judged this device The rationale for this makes sense—even though it's a line of thought that we've never considered."

Gao Wen took the information and scanned it slowly. He first saw a large-scale ring-shaped device, which seemed to be spliced ​​by a large number of segmented "components", like "ring segments" like building blocks There are many "towers" and "lenses" pointing to the sky in between, and in the center of the ring device, there is another huge facility, which describes its function and principle with a lot of data and notes .

Behind this drawing is a thick stack of blueprints, which are used to disassemble and subdivide all the structures of the ring device and the central facility. At the same time, each drawing is accompanied by a large number of parameters and notes— —Some of the notes also have the words "unfinished translation". Obviously, even the most professional star interpreters couldn't handle the task that suddenly fell on their heads.

Not long after his eyes fell on the subsequent drawings, Gao Wen realized one thing - except for the annotations, most of the content seemed to be incomprehensible...

This thing is too professional. Although he can still discuss a few words with technical experts on the general technical direction or some theoretical conjectures, when it comes to such specific technical details, he is really blinded. .

But this did not affect his majesty as an ancestor. Gao Wen just calmly looked at Jenny next to him: "I think the text on it has not been translated yet, can you understand it?"

"It's really impossible to fully understand," Jenny said frankly, "just from the general description, this seems to be a device with a very reasonable idea, and if it's just for observing the vibration of the magic tide, we don't have to fully understand it. The principle, all the construction parameters and technical details are there, and the Nuoyi people even sent a lot of alternative plans when the main plan cannot be realized. We only need to construct according to the drawings, and we are expected to complete this observation device—of course , There may still be many practical troubles in the specific implementation, such as certain components and our existing energy and data interfaces may not match, but these are all problems that can be solved.”

"... Is it feasible to simply follow the blueprints for construction..." Gao Wen had a serious expression on his face and whispered to himself. He weighed many things in his mind for a moment, but he didn't say anything for the time being. Instead, he focused his attention on On another pile of materials on the table, "Is that the relevant material of 'mind unification field'?"

"Yes, this has been received so far," Rebecca immediately handed the large stack of printing paper to Gao Wen, "Let me tell you, the progress of translation on this document is slower... I only translated the notes at the beginning and the main idea of ​​the title of each component blueprint, because the information from the Noi people has been sending over, and the Thorin monitoring station has temporarily stopped the full-text translation of the follow-up documents. Send the original data here directly."

Gawain nodded slightly while listening, and at the same time, his eyes had already fallen on the large pile of materials. He casually flipped through the beginning part, and soon discovered one thing - this thing called "mind unification field"... Much bigger than he imagined.

This is not a single device at all - it is completely different from the "magic tide observation device" in the first file.In the "Mind Unified Field" materials he obtained, there are a large number of "parts" that appear to be independent of each other at a glance. There are a large number of terminals called thinking connectors, a large-scale mind interaction center, and a complex connection structure. , and even... There are "background materials" with planets as reference blueprints.

In addition, the Nuoyi people also sent a large number of technical documents that do not belong to the blueprint. Due to the use of a large number of overly professional vocabulary in those documents, the star interpreters were unable to translate them for the time being. Mixed with countless numbers and arithmetic symbols, just looking at it makes people dizzy.

Gao Wen could only guess the function of those alien technical documents - he guessed that the Noi people were probably trying to make the "Loren people" understand the principle behind the "Unified Mind Field".

They are really trying to teach us.jpg.

Gawain shook his head, put aside the weird feeling that popped up in his mind for a moment, and turned his gaze back to Rebecca and Jenny: "What do you think of this information?"

"It will take us a long time to understand this huge and complex system. Its scale... has surpassed the previous set of 'Magic Tide Observation Device' by more than ten times," Jenny said with a serious expression, "The Noi people are sending two technical Obviously, a distinction was deliberately made when preparing the materials. If we only need to construct according to the drawings on the 'Magic Tide Observation Device', then on the 'Mind Unification Field'... they seem to hope that we can understand its principles. "

Gao Wen didn't speak, but his mind was full of thoughts.

He was trying to understand the motivation of the "Noi people" to do this, trying to find possible traps and uncontrollable factors, but in the end he found that there were few factors in the whole thing that were controllable.

Rebecca next to her sighed quietly at this time: "Actually, when I first heard about the 'Mind Unified Field', I thought it was a huge device, something like a force field transmitter. Use it to Create a large-scale 'shield', and then let everyone get in when the tide of magic comes. I really didn't expect it to be such an exaggerated thing... The global protection system is really global protection It's..."

"My initial thought was actually similar to yours." Gao Wen sighed softly, and then his eyes subconsciously fell on one of the pictures in the stack of materials.

It was a planet, and the Noi people used this planet to demonstrate the effect of the entire "Unified Mind Field" and its true... scale.

The nodes are all over the world, and the network covers the whole world. The mental unity field generator is not a device, but a planet-level facility group built by thousands of giant nodes.

No wonder it took the Noi people 400 years to build this thing.

Of course, during the "400 years", the special development process of the Noi civilization and the impact of their social changes should also be taken into account. Then they learned the truth of the magic tide, so the start of this grand project probably took place in an era of low productivity. At that time, it might take them a century to build a node, just like the silver elves used to spend hundreds of years In order to repair an energy station left by the original elves.

But in any case, even in Tarrond, which was once in its heyday, it is impossible for such a large-scale thing as the "Mind Unification Field" to be built overnight.

Jenny noticed Gao Wen's serious face, and she obviously knew what the ruler of the empire was worried about, which was also what she had been worrying about since just now: "To build such a set of things—let's assume that Noy There is no problem with the technical information sent by people, assuming that all the technical difficulties in the construction process can be overcome in an instant, just to build this thing, the scale of this project may take a century."

Gao Wen slowly put down the information in his hand: "And this is on the premise that everything is ideal - the fact is that we still need to understand the principle of this system first, to be sure that it can really affect the life of our planet. It is a project so astounding that it is impossible for us to devote the full power of the Alliance to it."

Jenny and Rebecca didn't say a word, just nodded silently—although the technical information sent by the "Noi people" made them excited and delighted, they didn't get dizzy because of it. They understood very well that what Gawain said You are right.

And Gao Wen was obviously worried about more than that.

"We still need more scholars, Typhon scholars, silver scholars, and scholars from other countries in the alliance—we need enough smart people to analyze every technical detail in these documents," he said quietly, "Our 'Alien Friends' really sent a 'gift' out of the blue..."

Chapter 1445 Urgent Need

While the experts of the Magic Technology Research Institute were busy analyzing those incredible alien technology blueprints, in the Sorin listening station in the east of the Holy Spirit Plain, messages from "Noi" were still being sent.

Bud Wendell sat in his seat, concentrating on monitoring the working status of a series of equipment connected to the main antenna, and in front of the printing device next to him, various technical documents including blueprints piled up again. After hearing the news, many other monitors and technicians also came to the hall, watching the progress of the data transmission with him.

Due to the limited efficiency of the superluminal information encoding currently used by the Noi people, it is unknown how long this transmission process will last. It is already time for Bud to "get off work", but he has no intention of leaving his post at all.

Just working overtime, how could he miss this historic moment?

"The amount of these materials is astonishing..." A voice came from the side, with strong exclamation, "They actually sent all these things in one go, but this level of technology shouldn't be some kind of ...'core secret'?"

"Who knows," another colleague's voice sounded, "Perhaps the Noi people and our way of thinking are different, and they probably don't think there is anything wrong with sending this kind of core secret, and of course it may be theirs. Something happened on the side, the situation forced..."

Bud looked up at the two colleagues who were speaking next to him: "Don't you have your own place?"

One of the colleagues laughed and patted Bud on the shoulder: "We are off work, come to see you work overtime."

Bud: "...you will have no chicken legs to eat in the cafeteria next month."

"Don't stop, we're just curious," the colleague immediately smiled, and then his expression became a little more serious, "The Star Breaker has temporarily given up the translation of the materials, and we are sending the original documents directly to The imperial capital, and His Majesty the Emperor has already known about this matter, and he is personally watching the progress of the matter."

Bard nodded lightly, not at all surprised by this—of course His Majesty Gawain will pay attention to this matter. Now, the information from the other side of the starry sky is enough to affect the fate of the entire world.

He was just a little bit emotional, and felt that he had become a member of this historical process—in a way he had never imagined.

When he was transformed into a dark druid by the end of all things, how could he have imagined that one day he would sit at a work station and receive blueprints from aliens?The turning point between these can no longer be described by 180 degrees. To use a popular saying in neural networks to describe it, it would be like crossing the script...

A slight sound of roots rubbing suddenly came from behind, Bud calmed down the thoughts that were scattered in his mind, and then heard Ms. Bertila's voice behind him: "Let me check the situation— —Is the data still being sent over there?"

"Yes, Ms. Bertila," Bud nodded, and at the same time turned on another magic net terminal, so that the holographic projection showed many readings about the main antenna and the "Noi signal", "The signal strength has been maintained at It’s a very high level, and the stable transmission time has exceeded previous records, but the Nuoyi people didn’t say anything except for sending these technical materials.”

"They seem... urgent." Bertila's incarnation quietly watched the data projected on the magic net terminal, and in the larger and more sophisticated senses possessed by her body, she could clearly feel the main antenna It is buzzing in the canopy of its own tree, and a subtle energy vibration is trembling in the atmosphere. Unseen information is projected from the distant star sea, resonating slightly with the magical environment in the atmosphere of this planet. I don’t know if it is an illusion. From this indescribable "Qingming", she seemed to feel a kind of... restless emotion. This emotion came from the civilization that was light-years away, and it might just be an illusory shadow in her heart.

And at this moment, she suddenly felt an obvious pause in the operation of the main antenna, and immediately after that, there was a buzzing sound representing the cut-off of data from the monitoring terminal in front of Bud.

The transmission of the technical documents that the Nuoyi people kept sending them finally stopped, and the entire monitoring system returned to silence for a while. All this happened so suddenly that the people gathered here hadn't reacted yet, and they subconsciously looked at the connection A holographic projection on the total system - at the moment there's just a little wobbling background noise.

And after such silence lasted for a few seconds, Bud suddenly heard a short tremor in the monitor earphones, and then, he saw a paragraph of alien text appearing in the holographic projection—always paying attention to this The star interpreters of this piece of information acted immediately, and the translation work was quickly completed. The words of the common language appeared under the pulsating alien text in the projection——

"We hope to talk to you again as soon as possible - all of Noi civilization."

Bud and his colleagues looked at each other.

……

"This is the last sentence they sent—it was also the only sentence spoken by this Noi civilization during the entire transmission process," said Jenny at the Institute of Magic Technology, a document just sent by the Sorin monitoring center. Handed it to Gao Wen, "After that, the communication was cut off, and 'they' seemed to be waiting for our response."

"...The situation doesn't seem right," Gawain frowned subconsciously. "The Nuoi people may have encountered some trouble. I always feel that they are acting a little urgent this time, even a little... anxious."

"I feel the same way," Rebecca nodded immediately, "Could it be that they are about to usher in a wave of demons soon?"

"Then this is not good news—our planet is only a few light-years away from them. Although this is an extremely far distance for mortals, on an astronomical scale, four light-years is just a short distance away. If they That place is about to be engulfed by the demonic tide, so we probably don't have much time to be safe here," Gao Wen said slowly, "and...we are not sure at what speed the demonic tide is spreading in the universe."

"Even if the spreading speed of the demon tide is determined, it doesn't make much sense—we still have to find a way to determine the direction of the demon tide's spread. It may spread from the direction of the Frost Sky Constellation, or it may sweep across us and us with almost no time difference. The planet of the Noi people," Jenny looked worried, "unless we build the 'Magic Tide Observation Device' now if we want to be sure."

"Magic Tide Observation Device..." Gao Wen subconsciously repeated the word, and then his eyes fell on Rebecca, "The data from Nuoyi's side has been transmitted, and the star solver will work overtime next time." Complete the translation of all annotations as soon as possible. Once all the files are translated, you immediately pack them up and send them to the technical teams at Typhon and Silver, and tell them that we need to evaluate these technologies in the shortest possible time Feasibility of data and level of risk."

Rebecca nodded her head while listening, and after Gao Wen finished speaking, she asked a little hesitantly: "If there is no major problem with the evaluation result... Are you really planning to observe the magic tide according to these blueprints?" Are device and mind unified field created?"

"According to my preliminary plan, I am afraid that the magic tide observation device will be built sooner or later, but the 'Mind Unification Field'..." Gao Wen frowned, "Let's put it away first, and understand its specific principles before we talk about it. Then Large-scale things... Even if you want to make it, you may not be able to make it, let alone it may not be useful to us."

Speaking of this, he paused, and then emphasized again as if obsessive-compulsive: "Remember, whether it is an observation device or a unified field device, we must ensure that they are 'safe and reliable'."

The sudden large amount of information sent by the Nuoyi people interrupted the rhythm of many people, but Gao Wen did not lose his composure in the process, no matter what troubles the Nuoyi people encountered, at least on the side of the Loren Alliance, " The technical information sent by Alien still needs to be carefully and rigorously evaluated before it can enter the follow-up process. This is the basic criterion he has set from the beginning.

The "foreign star technology" of unknown origin can be used immediately?The disastrous consequences caused by this reckless behavior are unimaginable. No matter how honest the Nuoyi people were in the process and how good the reasons were, Gao Wen did not dare to send them out casually. The blueprint that came from him turned into a real thing and built on the planet under his feet—what if it was a portal?What if it was a beacon guiding the fleet to jump?

But this is not because of being suspicious by nature, nor is there any unreasonable prejudice and disgust towards "alien people". They also have to face the entire Cecil Empire, even the entire alliance, and countless lives on the entire planet.

To put it bluntly, if he is a lonely adventurer, if he encounters an "ancient secret treasure" whose reason cannot be explained clearly, as long as the attraction is strong enough, he will go up if he goes up. ——But he is in his current position, and if he really wants to create a portal for alien invaders on his own planet, no one will give him a clue...

After all, he has done a lot of things about "leaving a back door in foreign trade technology"...

And take a step back, even if the Nuoyi people are really honest and friendly, the technology they send is indeed a good thing without any loopholes or backdoors, and Gao Wen has to consider putting aliens on his side. Is this planet really safe and harmless? If the physiological differences between the two races are to a certain extent, then the technology that is kind and friendly to one side is likely to become a deadly weapon if placed on top of the head of the other. —— Kraken This is the reason why 1 landlubbers can be drowned in the "comfortable, safe and fast submarine".

……

The starbreakers at the headquarters of Sorin's "Star Sea Project", the rune and magic technicians of the "Magic Technology Department" in the imperial capital, and experts in all related fields began to get busy. Everyone instantly had a reason to work overtime, and when Gawain returned to his study, Tyre, who was sleeping in his room for the fourth time today, was forcibly woken up.

"When will Antaveen's FTL communication array be activated again?" Gawain looked serious as he looked at Miss Deep Sea Ambassador, who was still bleary-eyed but had somewhat recovered her communication ability, "We need to communicate with Nuo as soon as possible. Reconnect with Yiren."

Tire rubbed her eyes, she finally sensed Gawain's unusually serious aura, and the whole fish became more energetic: "So urgent...is there something wrong with the Nuoyi people?"

"They sent a large number of technical documents including hundreds of blueprints in one breath today, and left a message at the end saying that they wanted to talk to us about something—I suspect that there have been unexpected changes 'over there'," Gao Wen Looking into Tyre's eyes, "We have to find a way to figure out what happened over there as soon as possible."

Tire finally woke up completely, blinked her eyes, and said as she recalled: "According to the last news from the great witch Hathaway, the FTL communication array can be activated within two or three days——Anta The burnt-out components in the main antenna tower have been replaced by Wayne, and only final adjustments are left."

"Is it going to be another two or three days..." Gao Wen frowned, "But that's the only way to go. We will contact Nuoyi immediately after the FTL communication array is restored."

Till nodded: "Understood, I will go to the zoom array to contact Antaveen's sisters later."

Gao Wen exhaled lightly, but his tightly locked brows did not loosen at all. After pondering for a moment, he still couldn't help muttering softly: "But this is not always the way..."

"Ah?" Tyre didn't understand, "What's not a solution?"

"The status of the FTL communication array," Gawain tapped the table with his index finger, "repeatedly burned and repaired, each time it can only communicate with the 'opposite side' for a short period of time, and then it will take at least a week to recover Fixing the antenna...it's too late."

"This...Her Majesty the Queen did mention this to me," Till thought for a while, unconsciously drawing circles on the ground with the tip of his tail, "She said that the FTL communication array is barely functioning now. Relying on this kind of makeshift equipment to join hands with a civilization that is light years away to fight against the doomsday, it will definitely delay the event in case of an emergency.”

Gao Wen's upper body leaned forward slightly: "Is there any better solution?"

Tyr spread out his hands (and the tip of his tail): "The sisters at Antaveen are already trying to modify the internal structure of the main antenna, but Hathaway says it's very difficult - to make that thing work It's already a miracle, and it's hard for miracles to happen continuously."

"By the way... what is the reason why the main antenna was burned?" Gao Wen couldn't help asking curiously, "Although I may not know professional technology, I am very curious about it."

"Ah, I'm not too clear about the detailed explanation. I know that the reason is related to the failure of a resonant crystal at the core of the main antenna—it can't be said to be a failure. The load causes the energy in the entire core area to accumulate continuously, and finally breaks through repeatedly..." Tier explained to Gawain while recalling the "news" he heard when chatting with his sisters last time, "press What the witch means is that unless we can find a device that has a very high energy density, can withstand a huge energy impact, and can maintain an extremely stable energy output for a long time in a high-load system to replace this resonant crystal, otherwise the FTL communication Arrays can't be repaired..."

Speaking of this, she sighed: "It's easy to say, where can I find this thing, the resonant crystal used in the main antenna is still brought out from our mother star..."

Hearing Tire's babbling, Gawain couldn't help reaching out and touching his chin.

"The 'thing' you said... I'm afraid we actually have one..."

Chapter 1446 The Second Conversation

On the border of Typhon Cecil, in the joint research facility "Contract Fort", a large laboratory is brightly lit. Technicians from Typhon, Cecil, and the Silver Empire are busy in their respective positions, and a mage is observing Watching the crystal reaction on the central experimental platform, there are apprentices who are responsible for recording data, and scholars are doing complex calculations and lively discussions nearby, and at the center of all this is the star from the Viplandon Observatory. "Energy Crystal".

Above the platform in the center of the laboratory, only a palm-sized clear crystal is floating in mid-air under the action of the anti-gravity field. Many rings composed of runes reciprocate around this crystal in the air. On the surface of the experimental platform, there can be Seeing the neatly engraved rune array and the precision crystals inlaid at the nodes of the array, these things together monitor the process of the "energy crystal" releasing energy and self-charging every second, and it is also the first in the laboratory. Road safety barrier.
