It's still the familiar gate, the clean street outside the window, the simple and warm environment inside the window, as long as the system settings of the Kuafu world remain unchanged, everything here will not change over time, and only people will change.

"It's still the same here!" Qingyu, who was following Mengxian, said with emotion beside him, this sentence touched Mengxian's mind at once.

"yes, it hasn't changed at all."

The scenery here is the same as the first time Mengxian saw it more than ten years ago.

I wonder if there were any other crew members who used it as their place of relaxation and meeting hundreds of years ago? Mengxian couldn't help but stop standing outside the door of the bookstore, quietly feeling a strange atmosphere that burst in.

"You don't think it's been a long time." Qingyu continued, looking at the surroundings carefully, "I really miss it! ”

"Yes, I'm usually too busy at work," Mengxian opened his mouth and began to defend himself, which was a knee-jerk reaction, but after saying that, he also felt that this sentence was just a way to cope, and added, "After the work is over, you have to keep resting, so that you can better prepare for the next work, and ...... And Kuafu's world is so big, you should also look around, maybe you can meet the crew of other departments. ”

"Oh? Is that what you think? How did I not know you had such an interest in traveling and making friends? Qingyu said suspiciously that Mengxian usually almost only "stays" in a few fixed locations in the Kuafu world, and has never gone out at all.

"I've always had this thought," Mengxian rolled his eyes, deliberately avoiding Qingyu's gaze, but after looking left and right for a while, he found that Qingyu's eyes still didn't plan to let him go, so he took a few steps, opened the front door of the bookstore and walked inside, Qingyu muttered quietly, he didn't pay attention to listening.

A few minutes ago, Yao contacted Mengxian again, and the second active contact in such a short period of time was something he had never done before. Yao has become too much more than before, and it has been so long that Mengxian can't even remember what he was like. In the correspondence, Yao didn't say anything clearly, just asked him to come here to find him as soon as possible.

Now is the crisis moment of the Kuafu, the approach of the gravitational wind, everyone's mental pressure is increasing, and what makes everyone feel uncertain is that there is more bad news than good news in the public information so far, and the General Headquarters has no clear instructions on how to deal with it. At present, other departments other than the Ministry of Science and Technology are making every effort to overhaul the entire system and equipment of the Quafu, and strive to make the Quafu in the best condition to cope with the contact with the gravitational wind.

After so many years of research, they have preliminarily cracked the detection technology of gravitational vortices, and have also designed and completed several new gravitational wind detector models. However, after all, it is a preliminary electronic drawing model, which has great limitations in use, and under normal circumstances, only in the state of accurate orientation can the state and travel trajectory of the gravitational vortex be roughly measured, which is far from enough for the Qua Father.

In addition, the bigger problem is that due to the limitations of the spacecraft's existing technical equipment and materials, up to now, the Ministry of Science and Technology has only had time to produce three prototypes of new detectors, and the function of the test prototypes is limited, and the directional detection cannot meet the requirements of the design in terms of distance and detection angle.

Even if three detectors are working at the same time, it takes as little as 115 minutes to perform a close probe of all angles of space in turn using the traditional method, and 9 hours if the long-range detection mode is used. Under this kind of detection efficiency, the best warning and evasion time of the spacecraft in the original data cannot be reached at all. Because according to the historical data of the known state of gravity vortex motion, combined with the speed at which the spacecraft initiates evasion, the range and corresponding time of the detector can be determined, and the maximum time cannot exceed 40 minutes.

Mengxian could not avoid being affected by the oppressive atmosphere of the whole ship, during this time, he suddenly felt that his usual handy work began to become unfamiliar, and his mind would not be able to control his movements from time to time and make wrong operations, so that he needed to spend more energy to correct his mistakes.

Moreover, the number and process of maintenance work formulated by the power department have been accelerated several times, and it feels as if endless people are pouring around him, and the problems accumulated in the early stage are completely exposed in the moment of crisis. There is no way to do this, because in the eyes of the people, any problem can lead to the destruction of the ship, and now it can only be carried out in order according to the classification of the importance level after the computer simulation.

Mengxian also knows that this is not a situation he is facing alone, almost everyone in all departments of the ship is like this, he is now on duty, try to compress his rest time to cooperate with the department's requirements for maintenance work, although the rest time is mandatory to guarantee, but the mental exhaustion is not something that can be made up for by simple sleep.

Regarding Yao's invitation, Mengxian agreed after thinking about it for a while, Yao would not talk to him at this time about irrelevant things, and it must have something to do with the current crisis.

As soon as Mengxian entered the door, he saw that Yao was still sitting in the same position as last time, but the difference was that this time there were two familiar figures surrounding him.

"Sister Qingyu." Xiao Shan, who was leaning on the outside of Yao's body, did not participate in the communication between the other two people, and had been standing on the side and looking left and right cautiously, when he saw Mengxian and the two of them, he first screamed timidly, and then lowered his head and kept tugging at the corners of his clothes with his hands, not knowing what to do next, just like a child who did something wrong.

Mengxian saw Xiaoshan's childish movements, and felt a kind of love from the bottom of his heart, Xiaoshan's emotional settings were not the original program, or Yao deliberately set them. Xiaoshan, as an intelligent assistant that was later rewarded with Yao, was specially equipped by the General Staff, and its computing power and program structure were the best on the Kuafu. In the General Staff, the highest think tank directly under the commander-in-chief, the intelligent assistant personality setting as a standard equipment has always been based on seriousness and ability, but after a period of use, Yao was very dissatisfied with this setting, so he had the idea of rewriting, and soon after, with the assistance of his mentor, he made a large-scale adaptation of Xiaoshan's intelligent module.

After optimization, Xiaoshan's logic and computing power have been greatly improved, almost reaching more than 2 times the original, which makes Yao very satisfied. However, there are always gains and losses, and Xiaoshan's emotional program unit dealing with emotional intelligence has an unknown conflict with the unit in charge of logical operations, and after starting, it will fall into logical confusion in dealing with specific problems every once in a while, causing the system to crash and reboot.

Tutor and Yao thought of a lot of ways to improve but were unsuccessful, and later Mengxian proposed to simplify the perceptual program unit, so that Xiaoshan was dominated by the rational logic unit, and the logic unit was compatible with some perceptual program units, so that Xiaoshan's normal use problem was solved.

Since then, Xiaoshan has been dominated by an introverted elementary school student-like personality, although the tutor has made several plans to help continue to solve the problem of conflict between intelligent program modules, Yao did not agree, because after a long time together, Yao has developed feelings for Xiaoshan's personality characteristics, and Xiaoshan's ability in data processing is very strong, and has made up for the defects of character, after all, Yao believes that intelligent programs have too high emotional intelligence and do not have much practical value.

"Hello," Qingyu touched Xiaoshan's hair dotingly, and then hugged him to his lap, Xiaoshan still shy and couldn't raise his head, gently leaning on Qingyu's leg, still tugging at the corner of his clothes.

"Hello, Xiaoxue." Qingyu raised her head and greeted Xiao Xue who was sitting in Yao's position and only staring at the display screen in front of her.

Although Xiaoxue's appearance is a short, fair-skinned girl, her personality is cold and arrogant like a high king, and her serious face never smiles. Mengxian also found that every time they met, Xiaoxue would sit on the side and be busy with something, and even Mengxian took Qingyu into the door just now, she noticed it, and she simply glanced up.

Xiaoxue is Yao's auxiliary intelligence that has been with him since birth, and the functions and equipment are the same as Mengxian's Qingyu, and the intelligent program set up by the Kua Father is to accompany the crew to grow together, due to the particularity of Yao's intelligence at that time, Xiaoxue's function of learning human emotions has not been exerted like others, and Xiaoxue, who is with Yao, has felt a lot of negative feelings in the early days of learning, resulting in her current indifferent emotional expression.

"Hello, Qingyu." Xiaoxue raised her head and said politely, and then turned her head to Mengxian politely, "Hello, Mengxian." ”

"Hello, Xiaoxue." Facing the slightly cold Xiaoxue, Mengxian didn't care, he knew that Xiaoxue's attitude was equivalent to an ordinary person's warm hug.

"Why do you have time to ask me to come here?" When Mengxian smiled and said hello to a few people, he sat down opposite Yao, leaned back tiredly and asked.

The relaxed atmosphere created by several people made Yao's brows stretch a little, and his eyes looked at him with some brilliance, Mengxian saw that he was in a bad state, and asked with concern: "Haven't you had a good rest these days?" Busy at work? ”

"It's just that I haven't slept for a while," Yao blinked, and Mengxian seemed to feel that when he closed his eyes, he didn't want to open them at all, and muttered in his heart, "For a while?" How long has it been? ”

"Okay, there's not much time, I'll just say it." Yao stood up, walked over to Mengxian's side, and said. "Xiaoxue, the signal has switched."

"Okay." As soon as Xiaoxue's words fell, the scene around Mengxian suddenly went dark, and a huge stellar belt appeared in front of him, this image was very familiar, as long as it was the crew of the Kuafu, they could almost answer the same answer without thinking, the Milky Way Orion Arm, one of the cantilever arms of the Milky Way where the solar system is located.

The image began to expand rapidly to a point, as the spatial scale continued to decrease, the speed of image change became slower and slower, and it didn't take long for a more familiar star field to appear in front of Mengxian's eyes, and each star Mengxian could say its name without thinking, Tiangao III, Beihe III, Arcturus, Nanhe III, Tianyuan IV, and Sun......

The image is finally frozen when the Kwafu appears, the huge hull is only the size of a peanut, the spaceship is surrounded by a pitch-black and endless void, and the stars in the background are not many light years away, even the light is like nothing, making the Kwafu in the starry sky look so lonely.

"It's ......"

Mong-hyun didn't understand.

"You've got a good idea." Yao said sincerely, looking at Mengxian's even more puzzled expression, he added, "The idea of the early warning circle." ”

"Warning Circle!" Mengxian reacted suddenly, his expression was a little embarrassed, and the feeling of being questioned by everyone when he was online once again surged to his face.

At the end of the line, when the chief of the general staff consulted with the opinions of various departments, Mengxian's heart suddenly moved, and he proposed a method in human history that used noise-prone items as early warning circles, but it was immediately opposed and even ridiculed by everyone.

Mengxian was a little embarrassed at the time, but he didn't feel that there was anything wrong with him at all, but in the face of various questions, he didn't have a good response for a while, and in the end, the chief of the general staff stopped this argument in time.

Now that time is too short, these proposals that require a long period of argumentation will not be included in the agenda, not to mention that Mengxian's idea is too primitive.

Use small items to be placed around the ship from a distance to act as an early warning circle? What era is it now? Everyone will not think deeply at all at the first time, they will only be amused by this primitive method.

"At first, I thought this kind of early warning was too primitive and even a little naïve." Yao spoke very directly, and did not shy away from Mengxian's feelings. "However, then I calmed down and accidentally thought of your plan, only to find that this early warning plan is too in line with the current situation, the technology is simple, the setup time is short, and the main work can be done by artificial intelligence without consuming limited manpower...... Aside from the disadvantages, every conceivable advantage is needed right now. ”

"Is it really that good?" Mengxian himself didn't think about it, but at that time, there was a flash of inspiration in his brain, and when the high-tech technology route was blocked by the environment such as time and manpower, his subconscious changed angles and gave an idea that had not been verified.

"Not either!" Yao shook his head and pulled open a document in front of the two of them, which was densely filled with diagrams and text, he swiped up a few times, and the document flipped quickly, but it never reached the bottom. He shook his head again, closed the document, and dragged it onto top of the kuafu, where the empty space around the kuafu was filled with words and icons.

"Although the idea of this plan is simple, there are also great potential risks, but it is still a bit complicated to develop a feasible plan."

"The basic scheme is very simple, the spacecraft stops the phased acceleration, adjusts the flight state to a constant speed, uses a small aircraft to lay the existing discarded components and parts on the spacecraft in the form of concentric spheres as far away from the spacecraft as possible, and the transformed intelligent assistance system combined with the Sky Eye Radar is used to monitor all parts throughout the process, so that once there is a suspected gravitational vortex disturbance part operation state, the new detector can be directional detection, shorten the time of the detector rotation detection, and increase the reaction time of the spacecraft."

"There are also many questions about this, such as whether the laid parts can maintain their relative position with the spacecraft under the extensive influence of gravitational waves, and whether the laid parts will pose a new threat to the spacecraft after being changed by the gravitational vortex."

"How much range can give the ship enough evasion range;"

"Is there enough time to set it up now?"

……

"These all need to be calculated systematically, and I have considered some solutions, but there may be some details that I can't confirm."

"In the known data, except for the gravitational swirl affecting space, the rest of the properties in the gravitational wave range are relatively simple, as long as the spacecraft remains in a stable state, the position of the parts and the spacecraft changes little

The dodge position can be multiple intersecting concentric spheres. ”

The scope of the layout needs to be calculated by the scientific research department according to the requirements of the detector parameters. “

"The timing can be adjusted to meet the density of the layout,"

"Because every part is a consumable, we try to use a multi-level protection strategy when laying out."

……

Yao just simply said the early warning plan he had completed, Mengxian's thinking was already a little unable to keep up, fortunately, the two were more familiar, Mengxian understood Yao's way of speaking, Yao knew Mengxian's ability to understand, and after Mengxian listened to it, he could be regarded as initially understanding the plan.

Yao's ability is still so strong, if he hadn't lost time, he doesn't know how far he can implement his mentor's transformation plan now. Mengxian was a little sorry, but it was certain that the Father would be better prepared for this gravitational wind crisis.

"How?" Yao asked after looking at Mengxian with a twinkle in his eyes.

"I think it's okay, your plan is very detailed, and it's a very good complement to the current response system." Mengxian was sincerely happy for Yao, "I believe that the General Staff will definitely adopt it, you have to hand it over quickly, now the time is urgent, of course, the sooner the better." “

"It's up to you to hand over this plan!" Yao spoke quickly, his tone was also firm, and when he saw Mengxian's puzzled expression, he immediately added, "I am too familiar with the people in the General Staff, and this plan needs you to hand it over." “

"You mean ......"

Yao's words made Mengxian think about whether his previous excesses would offend some people, but it was wrong when he thought about it.

"No, no, when is it now, whoever dares to violate the reporting system, all favorable courses of action will be fully demonstrated."

"Trust me! It's best for you to mention," Yao said affirmatively, and when he saw that Mengxian was still refusing, he said immediately. "However, after this plan is successful, you must say that I did it."

"Huh?" Mengxian paused, thought for a moment and said, "Say it after success?" “

"Say it when you succeed!"

"Okay, I'll submit." Mengxian put his mind at ease, feeling that there was nothing wrong with doing this, if it was beneficial to deal with the crisis, this credit would be great, and then explain the situation would be equally beneficial to Yao's current situation.

"You go back first, now the time is tight, all positions are inseparable from people, and when I finish the rest of the details, I will send it to Qingyu, and the matter of reporting to the staff will be handed over to you." Yao walked back to his seat and called Xiaoshan to his side, and began to get busy.

"Yao?"

What's wrong? Yao is still immersed in perfecting his plan, constantly sending his new instructions to Xiaoxue, Xiaoxue faithfully executes Yao's instructions, staring at the void in front of him, constantly moving his hands in the air, and putting the instructions together reasonably and transforming them into a standard programming language. And Xiaoshan stood on Xiaoxue's side in a daze, his hands on the edge of the table, his eyes were empty, his figure was faintly shaking, and he was a little weak, it could be seen that he was in a state of extreme calculation, and he didn't even have time to deal with his own appearance.

"Why...... You've always had to hide yourself like this, and ...... same last time" Mengxian, who was supposed to leave, paused in his footsteps and did not turn around, but once again raised the question in his heart.

"Huh?" Yao stopped his movements and fell silent, but he didn't turn his head, just like the conversation just now, he had been avoiding this question for a while, and Mengxian felt that at this moment, he was really thinking about how to answer this question.

"Because the idea was originally yours......" Yao didn't stay silent for long before he said his answer, but he didn't turn his head to look at Mong-hyun, who stared at his side face and understood that Yao had once again rejected the question.

"But it's you who really got it done, and it's all your credit that this plan is so perfect now, and I, my simple idea, will only make everyone laugh, and it's you who made it a plan that amazes everyone." Monghyun continued, his voice getting louder as he became a little emotional. "And with this program, you can re-enter the General Staff and start ...... again"

"What's the point?" Yao suddenly interrupted Mengxian, turned his head and asked expressionlessly.

"If you don't, you may soon be ...... Return to ......" Seeing this expression, Mengxian was stunned in his heart, and the words in his mouth became messy, "Mentor, he definitely doesn't want to see ......"

Mengxian seemed to realize something in his heart, and immediately stopped what he was about to say, Yao's excitement, anger, begging, despair, decadence, emptiness...... Several true expressions from the heart kept reappearing in Mengxian's memory. Mentor, a taboo word between two people, separated the hearts of two people for nearly ten years, and turned the hopeful Yao into what he is now.

Yao is the most promising candidate to inherit the mantle of the mentor, this is not only the idea of the mentor, but also the idea of the top of the Father, even Yao himself thinks so, and Yao has been working towards this goal since he woke up. At that time, Mengxian felt that he could understand Yao's thoughts, as a human with superior intelligence, what else was there to challenge him as a meaningful goal in his life?

The work of tapping into the potential of the Father of Kua may be the work of several generations, more than a dozen generations, and it needs the best inheritance, and the better the inheritor, the more it can accelerate the progress of this plan. However, although the mentor had this idea for a long time, there was no suitable candidate, until the accident happened, and the mentor was no longer able to continue the inheritance, so he could only organize and store all his information, hoping that the next suitable person could inherit this responsibility without his guidance.

The mentor's wait was not in vain, and when his physical functions deteriorated to a certain extent, and everything was almost a foregone conclusion, Yao appeared.

"Mentor ......"

A strange light flashed in Yao's eyes, his expression changed slightly, and he immediately turned his head away, not giving Mengxian a chance to see anything.

Mengxian swallowed subconsciously and swallowed the saliva stuck in his throat, but the roar that had changed his voice just now still did not completely move Yao. Mengxian sighed softly, and when he was about to turn around and leave, he heard Yao's next sentence.

"You...... Still going to see him? ”

"Yes, the ...... From time to time, look at the past. For some reason, Mengxian didn't say the word often, as if he was afraid of breaking something, what exactly Yao was thinking now, whether time had smoothed out something, he didn't know, and he couldn't guess.

"I'm not going to ......"

“…… I'm not going to face a few lines of foolish computer programs. ”

After Yao finished speaking, he continued to get busy, as if to divert his attention as soon as possible.

"The mentor is gone, you should let go of ......"

When Mengxian opened the door and left, he heard a voice from behind him, he didn't stop, and continued to walk forward, a voice sounded in his heart.

Put it down?

Who can really let go, you or me......
