"Wait, what is this?" Xu Xin picked up the last two cards.

It's [Mutated Beast Contract (Green)]. There are actually two Mutated Beast Contracts in the backpack.

Probably he plundered it from here and put it in his backpack, and died here for some unknown reason, so there was such a thing in his backpack.

Xu Xin didn't think much and put the two contracts directly into his backpack. In this way, he had five contracts, which just matched the number of rings that could be stored.

After putting the other things back into the blue-level backpack, he directly carried the backpack on his back.

The backpack is actually very small, and although it’s a bit awkward to carry two, it’s not a big problem.

The only heavy logs in the backpack were heavy logs, but the blue-level backpack reduced the weight to one-tenth, and his strength was now much stronger than before, so he had no pressure at all.

As for the broken blue-level leather armor, Xu Xin thought about it and put it on. He remembered that the weapon and armor making table had a repair function. Although he didn't know how much materials it would consume, it would definitely cost less than making a new one.

"With these logs and fine wood, when I go back, I can directly renovate the inside and outside of the tree house." Xu Xin was a little pleased, but he was only happy for a moment before calming down. After all, in this dangerous underground place

It is too early for the city to talk about renovating tree houses.

Xu Xin exited the room and closed the door.

Looking deeper into the corridor, he still couldn't see the end, but there were only a few rooms left, and there were only three doors left that he had yet to explore. As for the deeper corridors, there were no doors on either side.

I don't know where such a long corridor leads.

Xu Xin came to the door of the first remaining room. The door was unlocked. He was about to push the door open when Coco on his shoulder suddenly reacted.

"Ugh!" Coco yelled.

There's danger! Xu Xin narrowed her eyes, and her hand that wanted to push the door stopped in mid-air.

This was the first time Coco warned him of danger after entering this corridor.

According to Xu Xin's inference, there was probably a mutated beast locked up in this house. He took out the broom, held it in his left hand, and held the sword tightly in his right hand, and pushed the door open a gap.

The rotten wooden door made an unpleasant squeaking sound, and a putrid smell came out from the crack in the door.

It wasn't the damp and rotten smell that had been lingering since I came in, but a rotten smell.

That's right, it's the smell of rotting corpses.

Xu Xin has never smelled the smell of rotting corpses, but he has smelled the smell of rotting meat, and this is it.

Through the open gap, Xu Xin looked inside the door.

This room was very large, much larger than any room Xu Xin had entered before. It was like a hotel reception hall.

The hall was filled with tall, rusty iron cages, and the dense iron cage railings made Xu Xin think he was in a prison.

In each iron cage, there is a beast the size of a wolf lying on its stomach or inside, motionless. Each beast has faint blood-red patterns on its fur.

"Are these...mutated beasts? Are they...dead?"

Xu Xin opened the door and walked gently into the huge room. Compared with the small stone rooms that he entered before, this room was much larger, with a height of seven or eight meters and an area of ​​at least thousands of square meters.

In such a large area, only a few paths of about one meter are left between the iron cages, and the other locations are occupied by these rusty iron cages.

Xu Xin reached out and pinched the railing of a nearby iron cage. The railing had become very fragile due to long-term erosion, and it deformed with just a slight squeeze.

The mutated beasts in the cage were motionless, but they did not look like dead beasts. Although the air was filled with a putrid smell, these beasts looked normal and showed no signs of decay.

"Alive?" Xu Xin became more vigilant.

If these beasts survive to the end, these fragile cages cannot stop the movements of these mutated beasts.

Xu Xin's steps became lighter again.

After tiptoeing around the room, he didn't find anything other than this group of mutated beasts.

"There are so many mutated beasts here. Are they specially bred?" Xu Xin thought, "I wonder if the contract I just obtained can control these mutated beasts."

There are many types of beasts in the cage, including carnivorous beasts such as wild wolves and wild cats, omnivorous beasts such as wild boars and bears, and even herbivorous beasts such as deer and rabbits.

Xu Xin thought about it and decided not to try it for the time being. He still had two rooms to explore. If he used the contract to wake up all the beasts, these rusted iron cages would not be able to stop even ordinary beasts, let alone

Talking about these mutated beasts.

Withdrew from this room.

The next door is right opposite this door. Xu Xin walked to the door and reached out to push it.

"Hey!" Coco suddenly screamed again and tugged on Xu Xin's clothes. This time, its reaction was much more intense than in the last room. It tugged on Xu Xin's collar, as if it didn't want him to enter at all.

Xu Xin gently pushed open a gap and looked into the house.

What he saw through the crack in the door made Xu Xin's pupils tighten, she covered her mouth, and she almost didn't scream.

"What kind of monster is this?"

On the floor of the room, there were actually more than a dozen human bodies lying on the floor. These bodies were in different postures, as if someone had thrown them here directly.

If it were just dead people, Xu Xin would not be so frightened. Since he came to this world, more than 4,000 people have died in their area alone. Although Xu Xin has never seen their death, he will not be concerned about the dead.

Have a fearful attitude.

But these things lying in this room may no longer be considered human beings.

Most of them don't wear any clothes, but their bodies are covered with fine red and white fur. The fur is very short, about the length of a short-haired cat, and the red fur forms the red pattern that Xu Xin is very familiar with.

Some of them were wearing very tattered leather armor sets or even new gloves. Others, he could only vaguely tell through their hands, feet and the accessories they wore, that they might have been human beings.

"What is this? Mutated...human beings? And they are all survivors?!"

Xu Xin thought of the words carved on the stone table when she came in.

"They are all demons. I want to die if you kill me. You all will not have a good death..." The more Xu Xin thought about it, the more he felt his breath became short of breath. "Not only are mutated beasts being cultivated here, they are even being used for experiments on survivors?"

He turned back sharply and looked in the direction he came from. The corridor was still dark, except for the faint firelight swaying in the stone room at the end of the corridor where he came from.

The doors he had opened were still as they were when he closed them, with no sign of any monsters about to emerge.

"Hey." Keke called out softly and pulled Xu Xin's clothes back. The intention was very clear, telling him not to enter this room.

"Those hairy things on the ground, are they alive?" Xu Xin asked Coco softly.

"Huh." Coco nodded her little head.

Taking a deep breath, Xu Xin slowly closed the opened door again.

There is one last room that has not been explored yet, so let’s clear up the situation first.

The door closed also made a harsh "squeak" sound. Xu Xin paused at the door for a while with some guilt. Only when there was no sound coming from inside did she breathe a sigh of relief and look at the last door.

The last door turned out to be made of metal, and although this door looked a bit old, it didn't have any traces of rust and was even spotless.

Xu Xin tentatively turned the door handle and found that the only special metal door had no lock and was opened directly.

Coco on the shoulder did not react, indicating that it was not aware of the danger inside.
Chapter completed!
