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

Most of them were not wearing any clothes, but their bodies were covered with fine red and white fur. The fur was very short, about the length of a short-haired cat, and the red fur formed a red pattern that Xu Xin was very familiar with.

Some of them were still wearing very tattered leather armor or even new gloves, while for the others he could only vaguely tell from their hands, feet, and the ornaments they wore that they might once have been human.

"What is this? Mutated... humans? And they're all survivors?!"

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

"They are all demons. If they kill me, I'll want to die. You all will die miserably..." Xu Xin's breathing quickened the more he thought about it. "Not only are they breeding mutated beasts here, they're even using the survivors for experiments?"

He turned around suddenly and looked in the direction he had come from. The corridor was still dark, with only a faint flickering light in the stone chamber at the end of the corridor where he had come from.

The doors he had opened were still in the same state as when he closed them, with no sign of any monsters emerging.

"Hmm." Coco called softly and pulled Xu Xin's clothes back. Her meaning was obvious, telling him not to enter the room.

"Are those hairy things on the ground alive?" Xu Xin asked Keke softly.

"Hmm." Coco nodded her head.

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

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

The door also made a sharp "creaking" sound when it closed. Xu Xin stopped at the door for a while feeling a little guilty. Only when there was no sound from inside did he breathe a sigh of relief and look at the last door.

The last door was actually made of metal. Although it looked a bit old, it had no signs of rust and was even spotless.

Xu Xin tried to turn the door handle and found that this unique metal door was not locked but was opened directly.

Coco on the shoulder didn't react, which meant that it didn't realize there was any danger inside.

Xu Xin gently pushed the door open.
