Through inspection, there is no problem with the No. 3 sub-engine, as for why the main control hall has not obtained the information in the engine compartment and cannot find the reason at present, Dr. Wayne deduced that it is likely that a large number of aliens have a certain shielding energy after gathering together, and can even affect the work of the main control optical brain, of course, this is all speculation, and there is no way to confirm. After all, these speculations require some sophisticated instrumentation, which is not available now.

After starting the No. 3 auxiliary engine, the urgent need for energy problems was temporarily solved, and all areas of the Stan were activated by the gravity system, and then through the inspection of the main control optical brain cabin by cabin, the inspection confirmed that there were no aliens before daring to start the life cycle system.

The activation of the life energy system means that most of the cabins, except for the parts where the shell is broken, are under pressure, and humans can move freely in these places.

Now, the only thing that hasn't started is a few engine compartments with unmonitored main control optical brains, and among them, there are main engine compartments.

Dr. Wayne and Liu Fei discussed the specimens and data obtained from the No. 3 auxiliary engine compartment for more than three hours, and finally reached an agreement: the awakening of the alien is closely related to the temperature.

Once you've found the cause, it's easy to do.

Through the main control light brain, the temperature of the cabin around all the undetected engine compartments is reduced to the same temperature as the engine compartment, simulating the exact same environment as the engine compartment, and then, put on a spacesuit and enter the engine compartment, sure enough, this method is very effective, people enter another auxiliary engine compartment without waking up the alien.

When people see layers of aliens entrenched in the engine compartment, its huge number still makes people feel a huge psychological pressure, I have to say, this is a magical species, in this space that does not eat or drink, only a little temperature can be dormant, and similarly, only a little temperature difference, they can wake up immediately, and can be active in the cold vacuum world without gravity and oxygen......

Next, a large-scale clean-up campaign was launched, using a variety of engineering mechs to transport countless aliens to the antimatter incinerator.

Over time, by the third day, all the well-preserved secondary engine bays had been restored, and the Stan spacecraft was no longer a pile of scrap metal, it was even capable of interstellar voyages at a certain speed, but if the main engine did not return to work, it was not very different from the Locke 1's sailing ability.

In the past three days, Liu Fei has not been cleaning up with the people, he is doing a more important job, which is related to the survival of everyone: repairing the Stan spacecraft.

In the beginning, everyone had little confidence in repairing the Stan, and even Prince Morton did not think about repairing the Stan's spaceship, because they had no experience in repairing large construction machinery, and they were seriously understaffed.

In addition to the shortage of manpower, the most important problem is that the repair of a large spacecraft like the Stan is not only as simple as welding, but also involves many disciplines, physics, optoelectronics, metallurgy, etc., because the Stan damaged not only the shell, but also some of the optical pipe network hidden in the shell, etc., which is a very large and vast project, and it is impossible to complete it with personal strength and wisdom.

Because people didn't believe that Liu Fei could recover, people were busy cleaning the inside of the Stan spacecraft, and no one paid attention to Liu Fei at all, after all, it was more important to clean up Stan to be habitable for humans, perhaps, they would have to live here for years, or even decades.

However, people's thinking changed on the third day, because, in these three days, Liu Fei actually repaired the two most seriously damaged places, when people tested Liu Fei's work results through the main control hall, everyone was dumbfounded, and Dr. Wayne was even more sluggish, because the test data showed that Liu Fei's repaired parts had reached 100% of the technical requirements.

People's eyes began to fall on Liu Fei, of course, Liu Fei did not know that he was still obsessed with the restoration of the Stan.

No, it's obsession!

For Liu Fei, this was not a vast and complex project, but a work full of fun, and he was immersed in it, and he had no idea that his every move would shock people, especially Dr. Wayne.

In Dr. Wayne's eyes, Liu Fei became more and more mysterious, because, what he saw Liu Fei seemed to be omnipotent, Liu Fei's understanding of aliens had surprised Dr. Wayne at the beginning, and now, there seems to be nothing Liu Fei doesn't understand, from large-scale welding technology to metal smelting formulas, and then to the repair of photoelectric pipelines, these things make people spend their lives without learning knowledge, Liu Fei copes with it calmly, he is almost not stumped, often just a little thinking about the problem and solving it.

Liu Fei has experience in the construction of large-scale equipment, and the warping space where Xiao Qiangguang Brain is now staying is built by him independently, compared with the sophisticated and complex warping space, repairing the Stan is simply pediatric, in fact, Liu Fei is not very interested in repairing the Stan, this is just his side work, he is more interested in the large equipment in the maintenance cabin.

Of course, things are not as simple as people see, Liu Fei is not omnipotent, he is not a god, he doesn't understand a lot, he just has a strong assistant: Xiao Qiangguang brain.

Liu Fei more often completes his work according to Xiao Qiangguang's instructions, rather than making his own decisions, and it is from this kind of task-based work that Liu Fei absorbs the vast amount of knowledge.

If Liu Fei learned some manufacturing expertise when creating the warped space, and repairing the Stan spaceship, it was to let some messy knowledge in Liu Fei's head begin to run through it in a planned way, because, this time there is an essential difference from the creation of the warped space, in a strict sense, Liu Fei has only completed the tailing project of the warped space, and many components are just done according to the tasks assigned by the small strong light brain, which is between understanding and not understanding, and now this huge repair process, Liu Fei had to start from scratch, and he had to handle everything himself, which gave him the opportunity to understand the principles and functions of some process manufacturing techniques.

In people's eyes, Liu Fei's workload is very large now, but in fact, it is not as people see, Liu Fei is very easy, he just needs to operate some complex cutting-edge instruments and understand the principle, and most of the data analysis is done by Xiao Qiangguang brain.

Just as Dr. Wayne and the others thought at the beginning, it is impossible to completely repair the Stan spacecraft with their own strength, not because of how much work it takes, but because there is too much relevant knowledge involved.

The more I observed, the more strange it became.

On the left porthole, there is a destroyed armor plate, because this armor plate is connected to the porthole, its casting process is relatively much higher, but it is this armor plate with complex data, Liu Fei actually only took ten minutes to get it.

According to Dr. Wayne's idea, casting such an armor, first of all, you have to read out the data of the armor, and then read out the formula of the metal, etc., not to mention casting, just checking the data is a very time-consuming process, but Liu Fei actually only checked the damaged parts, and then, directly operated the automatic metal smelter to get the armor he needed, the process was so simple that people couldn't believe it, and the fact is that after the armor was welded, its data indicators fully met the requirements, which was perfect......

On the fourth day, Liu Fei was called from the maintenance cabin to the main control hall by Dr. Wayne, because there was a very important thing today: opening the main engine compartment.

Wayne has been cautious about turning on the main engine bay to avoid accidents, and now that most of the facilities have been restored, it is imperative to turn on the main engine.

"You think it's going to be dangerous?" Liu Fei was a little puzzled that Dr. Wayne hadn't turned on the main engine yet, only since he found out that the alien awakened and was affected by the temperature difference, Liu Fei's mind had not been on the alien, in fact, because of the tadpole, Liu Fei had always regarded the individual alien as an enemy, not the alien race as an enemy, and he never thought of exterminating all the aliens.

"It's not."

"Why don't you turn it on?"

"The main engine is the place with the largest space, if the alien has an IQ, then, the main engine should have a certain symbolic meaning for them, it is likely that the main engine has a lot of secrets related to the alien, so, I hope Mr. Liu can ...... with me"

"Let's go." Liu Fei didn't want to waste time, his enthusiasm for learning about the alien had been greatly reduced, he just wanted to hurry up and cooperate with Dr. Wayne's research work and get back to the maintenance cabin as soon as possible, where there was an inexhaustible treasure.

In fact, the research work of the alien is also very important to Liu Fei, and Xiao Qiangguang Brain needs to supplement the data errors formed in the past 160 years through Liu Fei's research, and it is precisely for this reason that Liu Fei did not refuse Dr. Wayne's invitation.

After setting the temperature around the main engine compartment, the two immediately rushed to the main engine compartment.

After priing open the door of the engine compartment with special tools, the two turned on the cold light that came with it, but did not activate the light inside the engine compartment.

According to the recent data obtained, the dormant alien is very sensitive to the temperature of the outside world, and even the slightest change will stimulate its bodily functions, and the linear brain inside the body will relax and wake up.
