As with older devices, the master program is also very primitively written, and many functions are very cumbersome to implement. The advantage is that the logic is relatively clear, and after reading it all the way, Xuanzang already has a preliminary plan in his heart.

"I'll make a mock version within today, and if it's okay, it will take about three days to complete the modification, and it's basically just manual work." He replied.

Several engineers were relieved and celebrated in a low voice, but they were still skeptical and asked Xuanzang a lot of detailed questions. Xuanzang gave them patient answers, tried to use plain language that they could understand, and after some explanation, everyone praised him for his knowledge and ability.

Wei Zheng had already seen his strength, but he still had doubts about whether he could complete such a large-scale revision of the main control program of Chang'an's Heart, and at this moment, after listening to Xuanzang's answer, most of the burden in his heart had been relieved. It can be seen that he does have a deep understanding of the way of programming, and that kind of eloquence and accuracy in some general details can never be faked.

So Wei Zheng immediately agreed to Xuanzang's request, agreed that he would stay in the core computer room for the past few days to concentrate on his work, and instructed all kinds of logistics to ensure his diet and daily life.

As for Xuanzang's request to close the computer room in the past few days and not let anyone except him in, everyone was a little hesitant. Xuanzang's reason is that he doesn't want to be disturbed, but in the eyes of others, he is very worried that he will take the opportunity to do something, and with his technology, he will leave any backdoors and hidden dangers in the main control program, and none of them can check it.

"If I really want to do that, you won't be able to see it even if you're watching." Xuanzang was a little crying and laughing, and said to them, "And that won't do me any good." Rest assured. ”

Wei Zheng thought about it carefully and felt that he was indeed reasonable, so he agreed. I'm just going to report this to the overseer right away.

After the engineers left, Xuanzang connected the wasteland assistant to the terminal, and there was no floating projection screen and interface, which was too tiring to operate. An hour ago, the Wasteland Assistant had sent out a shock that he had received a message, and he hadn't had a chance to check it until now.

Yang Jian was satisfied with Xuanzang's efficiency, and as soon as he entered the shelter, he came into contact with the target, which made up for the time wasted in the lizard demon before.

He asked Xuanzang to further collect what Shenfang did in Chang'an, especially the communication with the management. At the same time, he also asked Xuanzang to pay attention to the ability shown by Shenfang, the information of this new scripture learner has a high degree of confidentiality, and many aspects are still missing.

According to the information he obtained, the westward journey began in about forty days. It is possible that Tianzhu will send someone over directly, but the specific form is unknown, so Xuanzang should pay attention to it.

After reading several messages from Yang Jian, Xuanzang opened the last anonymous message, and fortunately, it was sent from FTB.

Radio communication is a blind spot under the current surveillance network, but frequent use still has the potential to be exposed. Yang Jian and FTB both have corresponding anti-surveillance measures, but Xuanzang's wasteland assistant is too backward, so FTB asked him not to use active communication before.

On the day they left the Black-robed Men base, the FTB had already begun its operations. It took advantage of the negligence in the manufacturing plant to collect enough parts in the scrap area of the underworld, assemble a black impermanence, replicate a control system, and falsify all the logs. With it as a stand-in, FTB can take the opportunity to break away from the underground wireless network and move freely.

Now that it had managed to escape, it sent a message to Xuanzang saying that it was on standby within five kilometers east of the Chang'an Vault. Due to the fact that it is not connected to the switchboard due to the detachment from the wireless network, the Soul Recovery Module is no longer usable, and it currently has no attack capabilities.

However, it modifies the module's function to emit low-frequency interference waves at humans within a range of 200 meters, temporarily paralyzing their consciousness.

Everything has been arranged, and Xuanzang began to repair the heart of Chang'an, and at the same time thought about the reward he would ask for this time.

With the degree of development of the Chang'an Shelter, those parts should be there.

……

……

In the highest control room of the Vault, a tall middle-aged man sat in the center of the room, his stubble face showing exhaustion.

In front of him is a group of curved monitoring screens, mixed with various terminals and a small number of holographic projections, and the dazzling exponents are constantly changing, showing all aspects of the entire Chang'an.

"Is there something wrong, Superintendent?" Wei Zheng asked tentatively. He had just told the other party the good news that the crisis in the heart of Chang'an had been lifted, but what he received was silence and still worried eyes.

He added: "It's going to take time to verify, but it's only three days. Three days later, or just tomorrow, if he fails to come up with an effective solution that will allow us to see tangible results, and then it will be too late to start the immigration program, he will also be punished as he deserves. And if he succeeds, wouldn't it be a great ......"

"That's not what I'm worried about." Li Shimin pressed the controller on the armrest of the seat, then stood up, and walked to a monitoring screen with his hand, "Don't you think it's a bit too much of a coincidence?" ”

"What does a coincidence mean?"

Li Shimin lowered his head and fell into deep thought.

Two years ago, he had that incredible nightmare, and shortly after receiving the revelation, Shenfang came to Chang'an to give lectures and calm the emotions of the shelter's residents. Now that the heart of Chang'an is in crisis, it happens to usher in a Xuanzang at a critical moment, and it is so coincidental that he has mastered the programming technology that has been lost for a hundred years to help the shelter survive the difficulties.

"I thought this reactor failure was a sign that it was time for us to leave." He sighed, "Why, Chang'an has existed for hundreds of years and has not been destroyed?" ”

Wei Zheng said: "Perhaps it is the true will of the gods to survive this crisis, and that person is the one sent by God to save us." ”

Li Shimin laughed dryly and said, "Heh, save." Five hundred years have passed, how many times can Chang'an withstand salvation? You are the chief engineer, and you know better than anyone that every inch of this underground city is already approaching its limit. We have never succeeded in establishing a complete production chain, we always build what we lack, and when we need something else, we can only stop the original equipment and invest resources elsewhere. ”

He turned around and looked directly at Wei Zheng and said, "Five hundred years, even an iron nail should be rotten, why are you still holding on to Chang'an?" ”

Wei Zheng opened his mouth, lowered his head weakly, and was speechless. Indeed, he, like most of the Vault dwellers, had been born in Chang'an for generations, and it was hard to muster the courage to give up everything in what was probably the safest and most comfortable place in the wasteland.

Being born in Chang'an does not mean that you will be destroyed with it. Li Shimin always said this, but the immigrant faction he represented was a minority after all, and even if he was a supervisor, he could not change the hearts of the entire Chang'an.

"Do you remember the trip to the underworld I said?" He asked Wei Zheng again.

"Inspector-General, that's just a dream......"

Li Shimin snorted coldly and said, "Only you have always thought it was a dream. ”

"In any case, that's not enough to convince most people."

That's right, even a few of you can't convince you. Li Shimin looked at a terminal in the corner with a distraction, looked at the sluggish index above, and said: "Even if it is really a dream, it is not unreasonable." The migration programme will need to continue, and if energy supplies are successfully restored, it will need to be accelerated. Now it is not so urgent, and the size of the first batch of personnel can be appropriately reduced. ”

Wei Zheng nodded in response.

"By the way, what is the origin of that Xuanzang?" Li Shimin suddenly asked.

Wei Zheng replied, "I don't know, it was brought by Cheyenne." ”

"Tell Cheyenne to come to me."
