A group of people were standing in the entrance room of the descent, a distance of one hundred and fifty meters, to ensure that the people inside would not spit out or float up because of the descent too fast, so the speed was very slow, and when it was fifteen minutes down, suddenly Dai Xue fired a shot at the wall, and the piercing gunfire buzzed, and the drowsy people covered their ears.

"Vice, what are you doing?"

"Ha, give you a boost."

This shot did not damage the wall at all, it can be seen that its material is very tight, Jin Duan pulled out the knife and stabbed at the wall, and the knife was bent instead of using too much force, she said to Lu Su: "Ah, help me repair it." ”

"Can you toss a little less?"

"The walls here are tightly molecular, so to speak, very sci-fi stuff, and there's a main power station in the whole underground base that supplies power to these walls to compress the molecules on the surface. The reason why you see your own reflection in the walls is because of its very tight molecular structure. Kinoshita said.

"And this thing is super dense, isn't it?" Lu Su said.

"Yes! You know, the mass of a molecule is determined by the proton in the middle, and that proton is the equivalent of a walnut in a building compared to the volume of the whole molecule. The electrons are compressed inward by an external power supply, making the whole molecule strong. This wall can't be blown open by anything. ”

"That's amazing!"

"If you are willing to spend money, you can have the world's most cutting-edge technology in one place. However, to create this scientific and technological miracle, only the power of the state can do it. ”

Dai Xue said: "If you have time to popularize science, why don't I talk about the structure below." ”

"Okay."

She spread out the paper and began to illustrate as she drawn: "After going down from this passage, there is a passage below. In the middle of the entire underground base is a large vault, from which a slender passage radiates in all directions, and it is one of them that we will be waiting to walk on. ”

Rather than properly described, the structure of the underground base resembles a large spider lying on the ground, spitting out long cobwebs in all directions. This thing can almost be said to be an underground city, Dai Xue drew a map of it completely by impression, marking the role of each location, there are independent ecological rooms, bio-energy nuclear energy and mechanical research and development centers, arsenals, and places for life and entertainment, because the distance between the various sub-branches is too long, so there are many circular passages connected, making the whole layout more and more like a spider web. It's amazing that there is an independent subway inside, and of course the route they have to take can't be touched.

In addition, there is an independent power supply station and water supply station, where you can grow your own vegetables and grow protein synthetics (substitutes for meat and milk), which are all available in the city, and even sunlight, of course, is artificial. This is simply the construction of the city of the future.

"Actually, the real masters here are not the organizations, but the army." "We only have one-third of the access. ”

"No wonder I said anything about authority before, it turned out to be like this." Lu Su said, "This underground base is almost equal to the area of N City, so digging and digging, won't N City collapse?" ”

"No, it's so strong in structure and materials that a nuclear war, an earthquake, or even the end of the world can't destroy it."

"Why do you have to dig this thing under N City?"

"The prototype of the underground base was not made by us, in fact, when the Taipoor army occupied N City, they secretly dug down, spent a lot of manpower, and built an underground palace."

"It's scary, but can a man dig three hundred meters underneath?"

"They're not all human, yours are helping!" Dai Xue circled a piece under the entire underground base, "This is the site of the underground palace, which still exists there." ”…,

"The underground palace is used to live in people?"

"No, there's nothing in there, just four big stoves...... Demon Furnace! ”

Kinoshita scratched his face and said, "This matter is still a mystery, although some people in the organization are secretly researching that history, but there is still no progress. I can only guess that there is something under N City, so those people dug into the ground at any cost back then and refined demons there......"

"And then you're going to take over the ruins and build a base down there?"

"It's a long story." Kinoshita smiled, "This place has gone through several generations, and it has expanded little by little to its current size. The history in the shadows of these histories, like the N city above and the base below, although it will never see the light of day, is more bizarre than the ancient city above. ”

"Captain Mu, let's feel less emotional." Dai Xue said.

"Got it! The last thing is that these straight passages that you see are not really a whole. Each part is a separate component, and you can be careful about the intelligent defense module that can be loaded and unloaded like this room. ”

"It's like breaking through?"

"That's pretty much it."

Jin Duan yawned: "I just heard the three of you talk about cross talk here, and those who don't understand still don't understand." ”

"If you don't understand, please ask." Kinoshita said with a smile.

"Your good student is here." Jin Duan pushed Lu Su.

At this time, there was a sudden tremor between the entrances of the descent, and everyone began to talk in low voices, and Kinoshita Cicada said, "It may be in the middle of the position, everyone stand this way, and the door to the bottom is about to open." ”

After the chaotic footsteps, the door that Kinoshita Cicada said still did not open, so he waited for five minutes, and finally said, "Is there something wrong?" ”

"No way, each component has a self-test function, and the key components are replaced, and failure is impossible here......" Kinoshita's eyes wandered back and forth, and suddenly said, "Oops! Someone's got into the control room below! ”

As soon as this remark came out, it immediately caused an uproar, they were now in a position that could not be high, and if someone entered the control room, it would be easy to kill them. Unity of mind does not apply here, whether it is one person or a hundred people in the entrance room, it is just as insignificant.

The cicada was half-kneeling on the ground, pressing his hand to the floor, wavulating a small piece of the ground, and then he turned his gaze to Yibi. Yibi released a few sparrows and flew out, scouting seriously with her eyes closed, and everyone waited with bated breath for the results.

"We stopped in the middle." She said lightly.

"Is it in the middle? Is there a big ring underneath? ”

"Yes, that thing is blocking us."

"Everything is fine...... "is there something down there?" said Kinoshita. See the big gear up below? ”

Yi Bi shook his head: "No!" Suddenly, he said, "Wait, it's ten meters down, it's turning ......."

"Do you go up while turning, or do you turn in place?"

"No rise, turn in place, and fast!"

Now the situation they are in, Lu Su has roughly sketched it out in his head. The big gear on top stops in the middle, and the one below turns quickly at a close distance, and they are in a position where they can't go up or down.

Someone anxiously asked, "Captain Mu, what happened?" ”

"If I'm not mistaken, a layman has entered the control room, and it's a good thing he didn't add a smart defense module to this room, otherwise we would all die here. Needless to say, this guy is clearly trying to trap us here. ”

"Is there a way? Captain Wood. Yan Butterfly said.

"I'll go down and settle him and take back control."

"It's too dangerous to be alone! If you fall into a trap, you'll be in trouble. ”

As he was talking, suddenly someone screamed from behind, and when several people looked back, they vaguely saw a huge flesh wing flashing. Suddenly, someone pointed to the side wall and shouted, "He's in the wall!" ”…,

I saw a team member being dragged by a humanoid bat, flying in that mirrored space, and quickly flying farther and farther. It was gone in the blink of an eye, and then a long scream came from below.

"It's a trap!"

"No!" Kinoshita Cicada flatly denied, "This can't be a mechanism!" ”

In any case, the sudden appearance of a humanoid bat from the mirror space was too incredible, and Lu Su could only think of one person. The most troublesome enemies appear in the most troublesome places, and this is bad.

At this moment, a humanoid bat suddenly flew out of a wall, and it "whirred" out of the mirror, and rushed towards everyone. Yan Butterfly pulled out the knife and quickly accumulated red sword qi, and when he was about to release it, Kinoshita Cicada grabbed his knife, and the whole knife turned into a wave dynamic: "Can't use it!" ”

The two of them lowered their bodies to avoid the rushing humanoid bats, and because everyone was huddled together, they couldn't fight back at all. Suddenly, a pair of slender bone arms stretched out from behind Lu Su, grabbing the humanoid bat like a sparrow, but the latter dragged her to fly above, seeing that Jin Duan was about to be dragged into the mirror.

"Let go!" Lu Su shouted.

Fortunately, at the last moment, Jin Duan cut off Shura's crazy bones, she fell, and Lu Su caught her. But the crisis has just begun, and from time to time human bats appear in the surrounding mirrors, grab a person and drag them into the mirror, and then there is a scream of falling from outside. Standing back to back, they could barely resist, but this unimaginable attack, coupled with the fact that the space here was too small, was simply powerless.

"Let's jump!" Lu Su said, "Jump on the gear below and find a way, everyone will die if they are trapped here." ”

If you're outside, you can at least let go of your hands and feet, and if you're trapped here, you can only be wiped out in the end.

"Okay, it's a solution!" Kinoshita Cicada pressed his hand to the ground, and a fluctuating exit opened in the ground, and Yibi said, "I'll go down and pick you up." ”

Then Yibi was the first to jump down.

"I'll go too!"

Jin Duan jumped down.

"I'll go down first, too."

"Sir, if the gecko robot appears, you shout the sound of 'peck, peck'." Kinoshita said.

"'Peck peck'? Got it! The old man didn't express his curiosity, and jumped down in agreement. From the fluctuating floor, the three of them could be seen falling on the spinning gears in turn, the flying Yibi, the brocade broken "long arm", and the old man's cigarette, which was very safe to pick them up.

Then the other mermaids jumped down, and the three people who fell first caught them one by one in mid-air, although it was extremely thrilling for the parties, but in fact it was very safe.

In the end, only Dai Xue, Insect Ting, Lu Su and Kinoshita Cicada remained, and Kinoshita Cicada said: "Ladies first!" ”

"Children first." Dai Xue said to Insect Ting with a smile.

"I'm not a child."

When Worm Ting was about to take a step and jump out, Lu Su suddenly saw the mirror in front of her move, like ripples on the surface of the water, and then a bullet shot out from there!
