The Jingneng subway is running very fast underground, and to Chen Peng's expectation, this thing is still running very fast, the speed displayed on the terminal has reached 500km/h, and the surrounding tunnel is not the shoddy cement wall he imagined, but a kind of metal that cannot be seen material, and these metals reflect cold lights, giving people a very solid feeling.

Tian Guoqiang noticed Chen Peng's gaze and said, "That's crystal energy alloy, a high-strength material after the combination of biological mutation alloy and crystal energy, and there are some very powerful technologies in it, I don't know much about it, anyway, this metal can self-replicate and 'self-build' according to the pre-set appearance, you see the tunnel is long, right?" In fact, not much raw materials are used, most of them are made by 'self-replicating' and 'self-building', and it only takes 3 days, which is very convenient and easy to use. ”

Chen Peng nodded as usual, but his heart was already turbulent, and the comprehensive assessment of the shelter in his heart was improved again because of this strange metal, because he had never seen this thing! Even if there is Xu Yun in the Wings of Freedom, I have never heard of being able to research this kind of metal material, which is completely beyond the common sense of human beings! He couldn't think of any 'mechanism' that could have created such a magical metal, and his genuine curiosity about the trip to the shelter was immediately enhanced.

Zuo Shang said indifferently at this time: "Since it's so convenient? Why is the chamber not made of this metal? Instead, use crystalline energy? ”

Tian Guoqiang said with a smile, "Because this metal has just been made for less than half a month, it has only recently been used, and our next plan is to use this metal in a large area, and we will use them in the future to build a new experimental cabin."

Zuo Shang paused and nodded slightly, Chen Peng returned to his position and Zuo Shang sat quietly and did not speak, Tian Guoqiang was also happy to be idle, he felt that today was the day when he jumped out of his mother's womb......

There was nothing to say all the way, in fact, it didn't take a few minutes, after all, the speed of the Jingneng subway was there, and it took less than ten minutes to arrive at the so-called main base shelter, when the door was opened, Chen Peng and Zuo Shang were stunned again, the main base shelter was not as 'small' as the No. 16 experimental cabin, at this time in front of the two was a huge metal door more than 50 meters high, all kinds of heavy industrial machines in and out of it, and the people on the ground were only as big as their fingers, only to see countless ' The villain's walk back and forth in this empty space, and a large number of mopeds and tractors are constantly shuttling through it, here is like a huge space port in a science fiction movie, all kinds of machines are dazzling but orderly, at least Chen Peng can no longer find the words to describe the shock in his heart, watching a movie is one thing, but the scene in the movie is another thing to appear in front of you!

"This ...... What's the situation? Chen Peng looked at Tian Guoqiang in a daze, he didn't want to act like a turtle, but he really couldn't hide his shocked expression.

Tian Guoqiang smiled and said, "This is the distribution center of the SX regional shelter, and the materials of the major experimental cabins and small shelters are uniformly dispatched from here, in order to ensure the throughput, it must be built here to be a little 'bigger', of course~ In fact, because of the existence of the awakened after the end of the world, otherwise it is estimated that it will take countless years to build such a facility with manpower alone, but in the case of the awakened, the expansion here only took 1 year." ”

Chen Peng nodded stunnedly, and a sentence floated in his heart: This is worthy of being a state machine! And he could see that this scale was not only the façade, but the entire space of the main sanctuary was so large after entering through the gate! It may even be bigger, this is already an underground super city, and if this kind of infrastructure is handed over to the Wings of Freedom, it will definitely not be able to be built in 10 years without the help of its own system mall!

Infrastructure madness attribute ~ terrifying!

When Chen Peng was still shocked, a moped with a sense of science and technology stopped beside everyone, and a soldier in camouflage uniform jumped down from it, and said to Tian Guoqiang with a standard military salute, "Chief, I am ordered to come here to greet the guests!" ”

After Tian Guoqiang returned the salute, he was surprised: "Just yourself?" "This situation is a bit unexpected by him, according to the explanation of the upper echelons, Chen Peng and Zuo Shang are 'VIP VIPs' and should be greeted with great attention, but what the hell is such a warrior and a moped now? Even he himself was stunned~

Chen Peng's side doesn't matter, originally he didn't bother to fake an official tone with others, but now it saves trouble to come to such a soldier, and Zuo Shang doesn't care anymore, who he loves~ Anyway, he can follow Chen Peng wherever he goes.

Tian Guoqiang turned around at this time and said a little embarrassed, "I'm sorry, this welcoming ceremony is a little cold, the soldier said that there seems to be an emergency, and the high-level is holding an emergency meeting, so I didn't have time to greet the two in person, and I will take the two to the conference center now." ”

Chen Peng smiled slightly and nodded, "It's okay, there are not so many rules in the last days, and we are here to ask for help with some things, so there is no need to make a big fuss." ”

"Uh...... Help? Tian Guoqiang was stunned, he didn't expect Chen Peng to have something to ask for, if this was the case, he wouldn't be so 'courteous', anyway, even if he didn't say anything, Chen Peng would come to the main base in the end, isn't this a waste of saliva......

"That'...... Then let's hurry up," Tian Guoqiang finally pointed to the power lane with a smile.

Chen Peng didn't talk nonsense, he got on the moped with his feet, Zuo Shang followed, Tian Guoqiang finally got in the car and gave a password, and the moped started quickly, driving towards the huge metal door, because he knew that it was inevitable for Chen Peng to find a high-level person, Tian Guoqiang was simply too lazy to talk nonsense this time, and he no longer introduced the facilities in the main base to the two along the way, and Chen Peng and Zuo Shang went to see the freshness by themselves.

Chen Peng saw Tian Guoqiang's attitude change suddenly, and immediately looked at Zuo Shang with amusement, Zuo Shang glanced at Tian Guoqiang and pulled the corners of his mouth slightly, anyway, they had already come in, and the two didn't care about Tian Guoqiang's attitude, but they were a little unhappy.

The main base shelter is worthy of being the largest shelter in the SX area, Chen Peng previously judged that the space inside might be larger, but he never expected it to be 'big' to this extent! It's even layered! If he thought it was an underground megacity, now he's going to be x5 behind it! Five whole floors! Each floor is covered with countless buildings, up and down are scattered and orderly, each layer of the 'city' can see a lot of people and vehicles, and even can see a means of transportation like buses, like a peaceful scene before the end of the world, and the surrounding walls are lined with countless huge 'solar light bulbs', providing lighting while emitting a lot of heat, Chen Peng's first reaction is that he has entered the bathing city, is basking in artificial sunbathing......

Looking around in astonishment, the prosperous scene made Chen Peng's heart tremble again, I don't know how many times he was stunned today, and he established a conjecture about the shelter in his mind several times, and then was shattered by reality several times, Zuo Shang on the side finally couldn't help but show a surprised expression, is everything in front of him really the end of the world? Shelter? It's amazing!
