When Yuan Yi and Bam arrived at the sanctuary, it was almost evening.

This time was naturally different from the previous situation, and after such a long time, the sanctuary was finally rested, and it felt like a fortress in the air.

The bright silver metal tone with SF style, with the incandescent lights and sensor doors that will automatically light up when you walk through the aisle, and the barrel-shaped automatic cleaning robot that passes by him from time to time, makes Yuan Yi, who has not been here for more than a month, really surprised - it feels like two different worlds.

Bam on the side smiled and explained to him the changes, which were still on the periphery, and the changes on the inside were even more striking.

After passing through the first winding verandah, they entered the living area of the sanctuary, the last time Yuan Yi and the others came, it was still a depressed scene of people going to the empty building, but now, it has been arranged to be very livable. Not only that, everyone should remember that this place is a circular hollow, layer by layer tower, and at this moment, the top floor is as if it can really see the outside sky, scattered with golden afterglow and dazzling red glow, but Yuan Yi and the others just came in from outside, knowing that there are actually a lot of clouds outside today, and it is impossible to have such a scene in front of them.

"Speaking of which, this location is also virtual."

"That's right." Bam answered from the side.

"It's amazing, I can't wait to see the North House."

Ask her if she has discovered anything new.

However, before he could say the rest of the sentence, it was deliberately misinterpreted.

"Ah, I see, I'll serve you well tonight."

As soon as he heard this unheaving voice, Yuan Yi knew who was coming, he turned his head with the group, and sure enough, he saw a pair of anti-human eyes.

Yuan Yi was not surprised at all by the arrival of the North House, the main control room where she was located was able to monitor all the places in this holy house, in other words, this holy place had no secrets to the North House.

However, even if Yuan Yi has a strong psychological quality, he still has to take into account his image in other people's hearts, so he coughed pretending to be serious: "Ahem." North House, there are some things that can't be said nonsense, and it's not good for others to misunderstand. ”

How did he know that in the hearts of other people, he Yuan Yi had already equated with the hungry ghost in the color.

Beizhai nodded as if he was very understanding: "Understood, then let's wait until we get to bed at night." ”

Feeling the stinging gaze behind him, Yuan Yi really wanted to cover his old face.

In order to prevent her from saying any strange language, Yuan Yi hurriedly pulled her away and said to Bam: "You are responsible for the placement first, I have something to say to her." ”

Bam nodded with a smile.

Yuan Yi saw that he was smiling so treacherously, and knew that he must have misunderstood something, it seemed that he was having sex with the adulterer of the North House. The woman's reputation has been confirmed. But this is also something that can't be helped, who is called the person who is propagandizing, is this guy next to him?

glared at Beizhai, Yuan Yi pulled her away angrily, but there was a message from behind, "As a result, I can't help it in broad daylight?" "It's really good, I also want a wife with so big breasts and so beautiful legs and wearing black silk".

Yuan Yi felt that his head was already starting to hurt a little.

The two of them walked from the verandah to the core area of this sanctuary, the main control room, and on the way, Yuan Yi casually asked to the north house: "Did anything good happen during the time I left?" ”

Beizhai thought about it and nodded: "There really is one." ”

"Oh, what's that good thing?"

"I deciphered the core code of this sanctuary." Kitazhai said.

As soon as she said this, Yuan Yi remembered, the last time she came, although the Bei Mansion used the left 'key' to open the authority of the sanctuary, there were still some things that could not be activated because the permission was not enough, and she said this now, obviously she had found a way to solve it.

"Oh, what's the catch?" Yuan Yi suddenly came to his senses, but since he was not very proficient in these obscure things in scientific research, he hoped that Beizhai could choose some way to explain it that he could also understand.

"To put it simply, we can already master the core technology of the ancients, although there is still a lack of suitable materials and scientific and technological conditions for the time being, but as long as we take the time to study, even if we build a nuclear bomb, it will be no problem."

"Nuke, what's that?" Yuan Yi asked curiously.

"A nuclear bomb is a weapon of mass destruction that uses nuclear fission or fusion reactions that can be carried out independently and quickly, and instantly releases a nuclear reaction explosion produced by huge energy, which can easily raze the entire Yanjing Naval Command to the ground."

"What is this? It's horrible! ”

"There's something even better, using nuclear power, and electronics and alloys, and we can make satellites that can fly in the air, so that they can effectively help us monitor what's going on on the ground."

Yuan Yi pondered for a moment: "Do you mean the plane?" ”

It is not that there are no aircraft in this world that can be carried by people, but because of the low level of industry and the fact that the disturbance of the high air currents is very prone to accidents, etc., it has never been popularized - the most important thing is that the lack of effective navigation in the waterway is fatal at high altitude without any references.

But Kitazhai shook his head: "A satellite is a kind of spacecraft launched outside the atmosphere, because the area it is in is a vacuum zone, so the satellite will not be dragged down from the sky by gravity like an airplane." In addition, it will fly slowly along a set orbit with the period of the earth's rotation, record observations of the earth's surface, and feed back to the ground through communication......"

To be honest, Yuan Yi still didn't really understand what Beizhai was talking about, but honestly admitting it would make him look stupid, so he nodded pretendly, anyway, as long as it is the technology of ancient civilizations, it is for sure. However, after listening to it for so long, he understood one thing, that is, these things are still a vision that only exists in the imagination, and what Yuan Yi wants to see is the present that can be touched immediately.

However, he didn't want to discourage Beizhai's enthusiasm too much, so he could only knock on the side: "I don't understand these things, you just look at it, by the way, how are you doing the few things I asked you?" ”

With that, the two of them boarded the elevator together.

After the energy supply of the sanctuary is restored, there is no longer a need for groups of people to climb the ladder as before.

"Ding."

Beizhai stretched out his hand and pressed a button on the elevator, and the alloy door that was opened just now was closed, Yuan Yi felt the soles of his feet buzzing and shaking, although there was no change in his body, he also knew that he was continuing to rise above the horizontal height.

This is the elevator, what a convenient design, Yuan Yi thought to himself.

He was waiting for Beizhai to answer his question, but at this hungry moment, the indoor light that had illuminated the elevator suddenly dimmed, and then, the humming sound was also muted. (To be continued.) )
