This kind of call was a very wonderful feeling, in fact, what Su Yichen felt in his heart long before they set off, but it was not as strong as it is now. And as the Pioneer spacecraft got closer and closer to the Red Dark Nebula, this feeling began to become more and more powerful, but the strange thing was that Luo Yan didn't feel this call at all while holding this hourglass, which made Su Yichen puzzled.

"Could it be that this feeling is just for yourself?" Su Yichen has thought about this guess more than once, but why is it that only he has a sense? It's an unsolvable puzzle that you can only figure out when you get to your destination.

Not far away, Luo Yan is concentrating on designing formulas, as the red and dark nebula gets closer and closer, the road ahead is becoming more and more difficult, although the Pioneer spacecraft has a very powerful intelligent brain system, but in the face of such a complex terrain, the computing power of the intelligent brain system is somewhat unable to keep up with the requirements of curvature navigation.

You must know that curvature navigation is a completely different way of navigation from ordinary navigation, the calculation and capture of curvature also have to take into account the complex terrain avoidance requirements, and now the starry sky is full of extremely difficult roads, to search for a safe passage in advance in the case of countless space meteorites, asteroids and other different types of natural celestial bodies, according to the current computing power of the brain is somewhat difficult.

In order to solve this problem, Luo Yan plans to upgrade the brain system to deal with such a situation. And she is now making a complex formula design, which will be the core part of the brain system after the upgrade, once successful, the data calculation and resolution ability of the entire brain system will be increased by 30%, which is an undoubted leap for the already powerful intelligence.

As the creator of artificial intelligence for the earth's civilization, Luo Yan's talent in this area is unparalleled, and her work is almost complete, according to the design inference. The likelihood of success is enormous.

In order not to disturb Luo Yan's work, Su Yichen, who was observing the flight on the bridge, had been sitting there quietly, but he would glance at Luo Yan every once in a while. But every time I looked, I saw that Luo Yan had been busy, her brows either furrowed or stretched. And his expression continued to change as the work progressed.

After a long time, Su Yichen looked at the time, Luo Yan has been working continuously for almost seven hours this time, and working like this for a long time is not good for the body, but as a scientist, Su Yichen also knows that it is natural to forget to sleep and eat once he is studying and calculating, and the spirit of people at this time is very concentrated, and sometimes he will even have a flash of inspiration and complete the task in an unexpected way.

I want to ask Su Yichen how he knows. Of course, this is because he is also a scientist, and Luo Yan's current continuous way of working is also in him. But as her husband, seeing Luo Yan's slightly haggard face, there was some heartache in her heart, and after thinking about it, Su Yichen stood up, walked to the side and made her a cup of tea, and then quietly placed it in the most convenient position for her to pick up.

"Whew! It's finally done! ”

Who would have thought that as soon as Su Yichen put down the teacup, Luo Yan suddenly let out a long breath. He raised his head with a big smile.

"Done?" Su Yichen was stunned for a moment, he knew that Luo Yan's work was nearing the end. I didn't expect it to be so soon.

"It's done!" Luo Yan nodded, and then saw the teacup that Su Yichen had just put in her hand, picked up the teacup with a smile and blew it, and then took a sip: "The whole formula is completed, the next step is the simulation test, if there is no problem with the simulation test, then we can upgrade the brain system." ”

"Thank you. In fact, I don't care about upgrading these days, you can take your time, you see how tired you are. Su Yichen stretched out his hand to comb the long hair in her ear, and said with pity and reproach. At the same time, I regret that they didn't take Su Li with them when they set off for some reason. If Su Li were to walk with them by their side, Su Li's powerful ability as an artificial intelligence and the intelligent brain system on the Pioneer would be able to completely ignore the current situation.

Unfortunately, Su Li is not here, and they are still 100 light-years away from the internal coordinates of the Red Dark Nebula, and now they are only touching the outer perimeter of the Red Dark Nebula, and the road is so difficult to walk. Although the Pioneer spacecraft could still barely maintain its lowest curvature, the further it went to the red-dark nebula, the more complicated the situation became, and once the Pioneer had to fly out of the curvature in order to sail safely, the time it would take them to reach their destination in a normal flight state was simply terrifying.

Speaking of which, this is also to blame Su Yichen, he did not have enough judgment on this situation before leaving, which led to such an embarrassing situation. Otherwise, Luo Yan wouldn't have to work so hard, but fortunately, Luo Yan completed the work ahead of schedule, as long as the test is successfully upgraded to the brain system, then this problem will be solved.

"It's okay, we can arrive early after processing it early, isn't that what you've been expecting?" Luo Yan smiled and said to her husband, this journey is full of dangers, they even encountered the pursuit of an unknown fleet on the way, and almost hated space, fortunately, with the cooperation of the two of them, and this Pioneer spaceship, which was built with the greatest strength of the earth's civilization, was finally out of danger. However, they all knew in their hearts that the previous danger was only the beginning, and now when they came to the remote area of the dark red nebula, there might be more dangers hidden ahead.

After a few sips of tea, Luo Yan felt much better, and her tired body just now gradually recovered. She suggested starting the test now, and Su Yichen considered and agreed to her request, and then he assisted Luo Yan to start the test work, which was much easier than the previous design work, but it was also a relatively long and boring job. In order to let Luo Yan rest more, Su Yichen took the initiative to take on the main job of the test.

The whole test lasted for half a month, during which several small problems were found, and after several adjustments by Luo Yan, it began to tend to perfection, and after half a month, the entire test was completed, and according to the test results, it was still very satisfactory.

When the test is completed, then the next step is to upgrade the brain system, which is a very important job, once the upgrade fails, the Pioneer spacecraft will lose control of the central brain, although they can still repair it with their ability, but this repair process is very cumbersome and long. So before the upgrade begins. Su Yichen and Luo Yan conducted several preparatory checks to ensure the success rate of the upgrade.

The Pioneer spacecraft detached from the curvature flight state and temporarily switched to the normal navigation state, in which the Pioneer spacecraft first calculated the route data of the subsequent voyage and transferred the data to the auxiliary brain for storage. Next, during the test, the flight control of the entire ship will be temporarily taken over by the auxiliary brain. Compared with the central intelligent brain, although the auxiliary intelligent brain also has the name of intelligent brain, the ability between the two is worlds apart. According to the previous description of the earth's computer system, the central intelligence is equivalent to a huge and state-of-the-art supercomputer, and the auxiliary intelligence brain is just its epitaxial device, similar to the server or computer terminal system connected to the supercomputer.

Relying on the auxiliary brain, the Pioneer spacecraft can only navigate and fly according to the booking procedure and navigation route, and cannot perform complex calculations and self-reactions like the central intelligent brain. But in this case. They had to upgrade the central brain, so they took this helpless way.

"Disconnect the brain system." The command of the promotion was Luo Yanlai, and Su Yichen assisted. When Luo Yan gave the first order, Su Yichen, who was ready, immediately cut off the central intelligent brain system and the auxiliary intelligent brain, including the connection status with the control system of the entire spaceship.

"The connection has been broken!" After completing the operation, Su Yichen replied.

"The central brain goes into hibernation."

"Sleep countdown 30 seconds, 29...... 28…… 27…… The central brain initiates hibernation. ”

"Cut the brain core control database connection."

"Core Control Database Connection Cut......."

"Power off!"

"Turn off the power to complete ......."

“……。”

One order after another was issued, and Su Yichen carried it out meticulously. By the end of the last command, many of the equipment inside the bridge of the entire Vanguard spacecraft began to stop working. Because these devices are driven by the Central Brain, in the current state of the Central Brain being completely shut down, only a part of the basic equipment is still running under the work of the auxiliary Brain.

The next most important moment is the upgrade of the central brain system. With Su Yichen's assistance, Luo Yan began to upgrade the core data and formulas, including the program, which lasted nearly five hours. When it was finished, both Luo Yan and Su Yichen were sweating profusely, and at the same time felt extremely tired.

"Take a break, won't you?" Su Yichen took a towel and wiped Luo Yan's sweat and asked.

"However, let's get started, and if there is a problem, we can adjust it as soon as possible." Luo Yan shook her head and said that she was not tired, and she was looking forward to the success of the upgrade of the Central Intelligence Brain.

What follows is the tedious work. Unlike before, all the steps are opposite, when Su Yichen executes the dormant state of awakening the central brain, the two of them are particularly nervous, because this is a very crucial step, if the awakening fails, then it means that the upgrade has failed, and once the awakening is successful, then the probability of the upgrade being completed is extremely high.

Although they are all confident, not to mention that previous tests have confirmed their abilities. But you must know that in the eyes of scientists, nothing is completely 100% sure, and there are often times when you have made foolproof preparations, but it is precisely because of a small detail that you can't notice at all that leads to the loss of your efforts.

In order to ensure the awakening, Su Yichen and Luo Yan checked again, and only after making sure that there were no omissions in all their steps did they activate the awakening mode.

With a soft sound of "click", the wake-up mode was activated, but the central brain did not respond at all like a dead thing, and even the indicator light of the control center was still dim.

"What's going on? Is it ......? Su Yichen's heart suddenly sank, could it be that their luck was so bad? But they haven't missed anything from beginning to end, why can't they wake up? At this time, Luo Yan's expression was more anxious and ugly than him, in order to comfort Luo Yan, Su Yichen hurriedly said: "Don't worry, maybe the data exchange inside the brain system is underway, and it will take some time, Xiaoyan, you have to believe in your ability ......." ”

As soon as this sentence was finished, the indicator light of the control center suddenly lit up, and then the reaction of the central brain appeared, and with a very slight buzzing sound, some of the lights on the central brain that represented the operation turned on one by one.

Seeing this scene, Su Yichen breathed a sigh of relief in his heart, and at the same time showed a smile: "Look, isn't this done?" ”

Luo Yan also let go of the big stone in her heart, but this is not over yet, whether the upgrade is completed or not has to continue the next steps, she hurriedly asked Su Yichen to continue according to the steps, and an hour later, the Central Brain took over the entire system of the Pioneer spaceship again, and judging from the state and performance of its operation, the upgrade should be successful.

"I'll just say you can do it!" Su Yichen stretched out two thumbs to his wife, and praised sincerely, Luo Yan's heart was also very happy, at least from the current situation, the central brain system is running well, and the next thing is the actual test, if the flight test can reach the previous simulated test, then the upgrade will be a complete success.

In the following time, they first tested the upgraded Central Intelligence Brain System in a normal navigation state, and the test results were very satisfactory to them, and everything in the Central Intelligence Brain was running very well in the normal navigation state, without any problems. The next test will be the test in the curvature navigation state, which is really the most important thing. It is necessary to know that the flight speed in the ordinary navigation state and the flight speed in the curvature navigation state are completely incomparable, and the faster the flight speed, the way of navigation is different, which can verify the ability of the central brain after upgrading.

When the Pioneer spacecraft began to accelerate in the universe, a dangerous starry sky area, this area was full of various types of celestial bodies that can be seen everywhere, when the Pioneer spacecraft accelerated through these chaotic celestial bodies, and then directly entered the curvature navigation state, the central brain began to calculate and automatically adjust the course with an upgraded attitude.

"Everything is working and it's doing very well." Su Yichen, who was operating the spaceship and staring at the data, said to Luo Yan, and at the same time a heartfelt smile appeared on his face.

"Keep accelerating and see if anything changes." Luo Yan suggested.

Su Yichen raised his hand and made an OK posture, and then gave the order to accelerate, the curvature speed of the Pioneer spacecraft began to accelerate, and when it increased to twice the previous speed, it was no longer possible to maintain the normal curvature with the computing power of the original brain system, but now the entire spacecraft is still flying with an intact attitude.

"Accelerate again! Increase to upgrade the forecast velocity. ”

"Understood!" Su Yichen nodded, and continued to accelerate the spacecraft, and when it increased to the predicted speed, the central brain system showed some signs of slight difficulty in calculation, but it could still barely maintain the flight at this speed. It is not like the original when the spacecraft accelerates to this extent, it can no longer fly with normal curvature, because the computing power of the brain has exceeded its design part, which greatly affects the safety of the Pioneer spacecraft.

At this moment, indicating that the upgrade of the central intelligent brain system was successful, the Pioneer spacecraft began to increase from the base curvature velocity, and flew towards the red dark nebula at a faster curvature speed. (To be continued.) )
