Everyone knows that there is an air-raid shelter in this mountain, but the sight after opening the big iron gate makes everyone stand up with hairs all over their bodies.

The bloody picture is nothing, mainly the smell from this shop, which is indescribable, and it is spicy.

Inside the Iron Gate is a huge space, and unlike the previously natural caves, it is almost entirely human-made.

The top of the cave is about sixty or seventy meters high, the length and width are more than 100 meters, and the cave wall is embedded with rows of small holes, and the outside of the cave is a cage door made of arm-thick steel bars, but now it has been twisted and crooked by some external force.

In the middle of the air-raid shelter, the dilapidated modern equipment was piled up in a mess, and the bones of giant mutant monsters were everywhere beside it, the skin and hair were almost rotten and dry, and some of them were already showing their white bones.

If you ignore the smell and look at it from afar, it's like entering some dinosaur-themed science museum.

There are no lights in the bomb shelter, but the roof of the cave should be a channel to transmit natural light from the outside world, and the sunlight is projected in bunches, which looks quite good.

Rong Tian covered his nose, the first one couldn't stand it anymore, held on to the wall at the door, and retched twice.

"Damn, this smells of bad."

It's okay if he doesn't describe it, Luo Yi couldn't stand such a vivid description, and he lined up next to Rong Tian to support the wall, and he also vomited.

The voices of the two came and went, scrambling as if they were having some kind of competition.

Mo Ran frowned.

"This must be one of Chen Zhuo's experimental bases, and there are almost three hundred cages on the wall."

Liu Qing frowned in disgust.

"There must have been a monster riot here, but the number of corpses here is not a tenth of the total, where did the rest go? After we came to this city, we didn't meet a single mutant creature except for a few bats and bugs in the cave. ”

Qin Zheng rummaged under an overturned and deformed table on the side, and pulled out a recording board from the heavy dust and hair under the table.

After turning two pages briefly, Qin Zheng said in a low voice.

"This records the dose and time of the drug injection to the animal."

He couldn't understand some strange symbols and drug names on it, so he turned around and handed the record board to Mo Ran.

Mo Ran took it and took a general look.

"Well, it's about the same as we guessed before, some of them are illegal drugs, and some are tranquilizers and hormonal drugs. If the person who configures this medicine is Chen Zhuo, then he is not only a pervert, but also a medicine genius. ”

Shen Zhong walked over from the side, looked at Mo Ran and said.

"I may need to take this notebook back to the experts at the institute."

Mo Ran nodded and handed over the board in his hand.

"Let's look again, and see if there are any other records or clues left here."

Everyone nodded and dispersed towards various corners of the bomb shelter.

Several people were searching separately, and Lian Yue and Liu Qing on the side stood together, whispering that they didn't know what they were studying.

Mo Ran held another record board in his hand, and looked at the two of them as he walked.

"What's wrong?"

Liu Qing shook his head.

"I'm talking to Lian Yue, you look at the man-made scale of construction here, compared to saying that this is built by Chen Zhuo after the end of the world, I prefer to believe that this place existed before the end of the world, because after the end of the world, whether it is manpower or material resources and other mining equipment, it is difficult to reach this scale in a short time."

Mo Ran nodded.

"I think so. But then again, although the scale of this place is large, it can accommodate about 300 mutated animals. Compared to the data given to us before, it is too much of a drop in the bucket. ”

Lian Yue snorted.

"Here's the problem, before entering the mountain, I paid attention to the size of the mountain, if it had reached this scale before the end of the world, then it was impossible for the builders to give up so much other space that could be used."

Mo Ran frowned.

"You mean to say that there is something else in this mountain that is the same as this, or to exaggerate a little more, the interior of this mountain may have been almost completely hollowed out?"

Lian Yue and Liu Qing were just about to nod in agreement, when they heard Luo Yi in the distance, a panicked sound, and then around the ground where he was standing, a heavy dust was filled, and Luo Yi's whole person disappeared in place.

The others were also startled and immediately raised their legs and ran over.

Luo Yi was rummaging through a cabinet that was buckled upside down on the ground just now, and the hair and dust on the ground were too thick, and he didn't find a mechanism under his feet for a while.

It is also Luo Yi's nerves, it stands to reason that with his speed, he can completely jump away when he reacts while stepping on the mechanism, but Luo Yi stupidly thought that he was just stepping on a stone under his feet.

The stone door on the ground opened two doors downward, and Luo Yi's entire body was instantly weightless, and he fell directly down the door along the ground.

Several people gathered around the edge of the cave and hurriedly shouted Luo Yi's name.

I only heard Luo Yi's long voice twice, and then sighed, and finally fell to the bottom.

It looks like the depth is not shallow.

However, when Luo Yi rubbed his ass and looked at him through the light cast through the hole in the top mechanism, he immediately gasped.

He landed on his left butt first, and fell down while lying on his side, just avoiding the countless sharp iron nails on the ground that were more than a meter high.

If he was directly pierced on the iron nail just now, then Luo Yi would have been pierced through his body in an instant, and even all the two halves.

"Oops, hey!"

The people above also saw the scene below clearly through the light, and they couldn't help but be scared in hindsight.

Lian Yue fixed the rope on the top and took the lead in sliding down the rope.

Luo Yi saw Lian Yue, and his tears almost fell.

"Brother, I almost died just now, I was scared to death."

Lian Yue to the end, stood firmly, and glanced at him a little reproachfully, which frightened Luo Yi's neck and hurriedly admitted his mistake.

"I was wrong, brother, you taught me before, pay attention to subtle changes."

Lian Yue didn't speak again, but groped around the cave and found a gate.

As the gate was pulled up, countless bright white weaving lamps lit up under the entrance of the cave, illuminating the entire underground space very clearly, and the stone wall of the entrance of the cave also creaked, and after a while, a telescopic steel ladder was directly poked out from above.

Qin Zheng first tried the sturdiness of the ladder, and then let Mo Ran and the others walk down the ladder in turn.

Although the underground space is not as large as the upper one, the main role here is not to imprison the mutant animals for experiments, but to control the central control room.

Luo Yi really hit the right direction by mistake.

Rong Tian patted Luo Yi, who was still rubbing his ass in a low-key manner.

"Yes, the first kiss was not in vain, and luck came to you."

Liu Qing, who had just walked down on the side, paused and glared at Rong Tian behind the lenses of his glasses.
