(),

After a period of searching, as Tian Zhen said, there were almost no useful things.

The folders in the cabinet were empty, and it seemed that they had been systematically destroyed during the retreat.

"The little devil has been secretly studying here for more than ten years, and he must have achieved great results, and he must have achieved great results in destroying it so thoroughly, and we must find out the real secret. ”

Tian Jia's eyes lit up and she seemed more motivated.

Tian Zhen looked around casually, and came out after a turn.

At this moment, everyone was in a state of mind to find a treasure, and no one noticed him at all.

He walked forward, and in the dark and secluded tunnel, it was so oppressive and gloomy.

His gaze was still calm, as if he was visiting a museum, looking at everything with a scrutinizing gaze.

In each cell, he stayed for a while.

He had walked through at least eight cells.

Suddenly, Tian Zhen stopped, and there was a trace of solemnity in his eyes.

The first five cells were all about the same size, but from the sixth onwards, the area of the cells was much larger, and there were many more strips of rags inside, and even the bloody aura on the walls was much stronger.

"According to the cruel methods of the little devil back then, there are at least ten prisoners in this cell, and at least 50 prisoners in this big cell, what does this mean?"

His face gradually became gloomy, and he took out the golden needle, reached into the lock, as if he was opening the door directly with a key, and soon opened the iron lock.

One thing these cells have in common is that what is left inside is the dried corpses of animals.

Perhaps because of the unique geography of this place, the animals that died here did not decay, but turned into dried corpses, similar to mummies.

Not only is the size of the cell expanding, but the size of the wolfdog-like animal is also increasing.

Tian Zhen walked in front of the huge dried corpse like a calf, broke its mouth, his face suddenly changed, and he gritted his teeth and burst out with a cold roar: "It's just a beast, exterminating human nature." ”

There were still some bone residues left between the teeth in the animal's mouth.

Obviously, all this scum came from the prisoners.

Tian Zhen searched for the knowledge in his mind and found that except for myths and legends, there were no such terrible animals in real records.

Regardless of the danger, he reached out and turned the huge body over.

Suddenly, he let out an exclamation.

Above the monster's head, he found a special place.

It was a knife cut.

Tian Zhen frowned, took out a scalpel, aimed at the knife and cut it.

The dried corpse is like hard leather, and even Tian Zhen used a lot of strength to cut it.

Tian Zhen frowned, these little devils actually operated on animals and placed them in various laboratories, do they want to build an animal army to fight?

Now it seems that this plan was aborted, because in the later stages of the war, there were no monsters.

But the evolution of these monsters is obvious, from the size of a normal wolfdog to the size of a calf now, which is really a bit terrifying.

When he opened his head, Tian Zhen was shocked, there was actually a part in the head of this monster that obviously did not belong to him.

It was a wafer the size of a fingernail that stuck to a neuron.

Tian Zhen is in disbelief, even now, to do this kind of surgery, it needs the world's top equipment and doctors to cooperate.

Did this little devil reach this point in medicine seventy years ago?

It's horrible!

The monster has been dead for too long, and Ida's experience was about 60 years ago.

So its body is dry, and the inside of its skull is naturally dry.

Tian Zhen carefully took out the chip and put it in a small box.

He had a lot of bits and pieces with him, but he didn't have to worry about having nowhere to keep them.

Tian Zhen carefully examined the monster's claws again, and his face became even more solemn.

This is obviously not an ordinary monster, and after so many years, its claws are still as sharp as iron claws.

The surrounding walls are full of paw prints, some of which are even three centimeters deep, which looks very shocking.

Tian Zhen came to the conclusion that the monsters in this room were not at the same level as the ones in front of them.

The people in these cells have probably been bitten to death by it.

With their bare hands and weakened, they had no chance at all in the face of this monster that was even more terrifying than a tiger.

Tian Zhen sighed, walked out of the door, and locked it as it was.

He opened the ninth cell.

As expected, the monster here was about the same size as the previous one, but he had survived for ten years longer than the first one.

It's terrible.

You know, the first one died 60 years ago, that is, the little devil at that time has been gone for more than ten years.

The little devils leave, who will feed them?

Tian Zhen shuddered.

The answer to this question, he really doesn't want to think about it, it's really anti-human and too cruel.

There were prisoners for food, and it lived for more than ten years without being tended.

This is already beyond the limit, because the life of a dog is only seventeen or eighteen years at most.

But the monster in front of him made Tian Zhen a little unbelievable.

It survived for 30 years without being cared for.

Because according to Tian Zhen's examination, the time of its death was more than forty years ago.

It's terrible.

Even if there were a room full of prisoners to feed it, it wouldn't have survived that long!

Tian Zhen was skillful, and after cutting open the head and taking the chip, he walked out of the room.

Touch!

Suddenly, there was a sound in the distance, like something hitting the iron door.

In this silent cave, which was already very infiltrating, suddenly there was such a loud noise, as if someone was grabbing his heart and pulling it hard, and the hairs on his whole body stood upside down.

There was a sound of footsteps, and Tian Jia and the others hurriedly ran over.

"Tian Zhen, where are you, don't scare us!"

Yang Jiayi shouted loudly, with some panic in her voice.

She was still very worried about Tian Zhen.

In such an environment, human psychology is very sensitive and fragile.

"I'm fine. Tian Zhen's voice sounded.

Everyone turned a corner and saw Tian Zhen standing in the passage, his face solemn.

Tian Jia was furious: "Tian Zhen, what are you doing? Why don't you act with everyone, you trespass like this, what if you encounter danger." ”

Han Kefei said angrily: "Disobedient people often die first." ”

Chen Liansheng snorted coldly: "I said a long time ago that if I didn't bring him, I would know that I would be holding back." ”

Only Yang Jiayi ran up quickly and looked at Tian Zhen with concern: "Are you really okay?" A loud noise just now scared us to death, don't be so skinny next time, it's easy to annoy people." ”

Tian Zhen said lightly: "It's not the voice I made." ”

"It's not you, it's coming from your side, who are you fooling? Han Kefei obviously didn't believe it.

Tian Zhen looked at Tian Jia with a solemn face: "Senior Tian Jia, I suggest that this expedition end here." ”

"No, we just came in, and we haven't gained anything yet, how can we give up halfway. ”

Chen Liansheng said in a weird manner: "If you are afraid, just say it, we can let you go back first, as long as you are brave enough to go out alone." ”

As long as Yang Jiayi looked at Tian Zhen thoughtfully, she knew that Tian Zhen was definitely not a weak and timid person.

He said that there must be a reason for going back.

"Senior sister, I also think it's inappropriate, this is the secret laboratory of the little devil, no one knows if there is any danger, we don't have professional equipment, let's wait for the country to send someone to deal with it after reporting it!"

"What's the matter with you two? You're still cowering when you've come to this point. Tian Jia said unhappily: "If you want to go back by yourself, we must finish exploring the remaining area before leaving." ”

Tian Zhen frowned and said: "It really wasn't the sound I made just now, you come to see these monsters, they are the test subjects of the little devils, using prisoners as prey and food, I suspect that some of them are not dead." ”

Everyone looked at it, but they didn't think so.

Han Kefei said: "It's just a little bigger than the first one, what's so special?"

Chen Liansheng sneered: "No matter how powerful these monsters are, but they have been locked in a prison cell for more than 70 years, they have already starved to death, how can they be alive? Tian Zhen, I really despise it, because I am afraid, I deliberately make a noise to scare us, you two go back, we will complete the survey work." ”

The three of them made eye contact, and they completely raised their hands in favor of Tian Zhen leaving.

It seems that they didn't want these two people to be involved in it in the first place, and it was better to go.

Tian Jia said: "Since you are afraid, go back first!"

Tian Zhen frowned and said, "Senior Tian Jia, there is really an unknown danger here, be careful." ”

"I have a hundred times more experience in exploration than you, I know how to deal with danger, you don't have to worry about it, since I have found out that this is the secret base of the little devils, not a tomb, there should be no mechanism, you barefoot doctor can also take a rest, so let's go and wait for us first, we will call you if there is anything." ”

Han Kefei snorted coldly: "If you are not convinced, come and see, where are the monsters lost?"

Tian Zhen smiled bitterly, of course he couldn't say that he had actually gone in, and he also performed an autopsy on the monster.

Although no monsters were lost, Tian Zhen was always uneasy in his heart.

It feels like you've become a prey, and you always feel like someone around you is spying on you.

But these three people were very resolute, ignored Tian Zhen's persuasion, and continued to go deeper.

Yang Jiayi said in a low voice: "Tian Zhen, this is not a big deal, right?

Tian Zhen sighed: "They won't stop until they reach their goal, let them be!"

"However, we are a team, so we will be gossiped about when we leave the battle. "Yang Jiayi's sense of collective honor is quite strong.

Tian Zhen said: "Haven't you seen that the three of them are in a group, and they have other plans, so I wish we weren't in front of us." ”

"Then we can't ignore it, this is the property of the state, how can we allow private people to covet it?"

The little girl said, turned around and chased forward, Tian Zhen couldn't catch her too late.

And in the depths ahead, there was a loud bang.
