"How did you get here?" Chen Xiao said in a low voice. "Isn't this the Crow's underground research institute?"

The place where Chen Xiao was standing was the underground research institute he had been to before, the place where the black crow was used to study transforming people and strengthening people.

But now this place is empty, and Chen Xiao also thought of a question, that is, if this is a research institute, then the cave just now is not deeper underground? Why is there a cave there? Could it be that the ant colony did it?

Chen Xiao shook his head, not planning to think about this problem anymore, but looking around here for an exit to see if he could find a way out as soon as possible.

But not only is there no exit here, not even a living thing, and the quiet environment makes Chen Xiao palpitate.

This is a normal human reaction, in extreme silence, the heart rate increases, and the subconscious mind is cranky, which is also known as the palpitation effect.

Chen Xiao feels this way now, but fortunately, he is very bold and his mental strength is not bad, so he doesn't show too much panic.

But even so, the place was still a little scary, all the rooms were opened, and the contents were scattered all over the ground, which, combined with the white light that kept shaking overhead, made this research institute even more eerie.

Chen Xiao turned around here and didn't find any exit, but only found a locked door, which seemed to lead to it.

But the material of the door was so hard that even his full attack could only make a small hole.

"So hard? Can't my strength break him? ”

"What a dish! Replace me! ”

At this time, the corpse king in Chen Xiao's body suddenly spoke, and the two quickly exchanged control.

The Corpse King looked at the door in front of him, twisted his shoulder, and threw a punch at the door.

But the result was not ideal, even he was only a little bigger than the pit that Chen Xiao smashed.

"Damn! This one is really hard! The Corpse King said angrily.

"It's a pity that this door doesn't have a keyhole, otherwise I would have opened it easily!"

Chen Xiao's ability is a good hand at unlocking, but at this time, this door without a keyhole limits his strength, and the scene becomes embarrassing again for a while.

Just when he was at a loss, he suddenly found that the lights in a room in the distance were flickering on and off, and the flickering lights made Chen Xiao couldn't help but be curious, and he wanted to go in and have a look.

But curiosity killed the cat, and after what had just happened, he didn't want to have any more trouble, after all, there could be no passage to get out of the room at the end.

"I'd better see if there are any clues around here, but it really doesn't work, so I'll have to go back the way I came..."

The place where he had collapsed before had not been completely submerged, and he could still be allowed to pass reluctantly, but if he ventured back, it was very likely that it would collapse again, and when the time came, there would be no way for him to escape again.

But this kind of anxious waiting was the most unbearable, and at this moment, there was a sudden sound of grinding teeth in the research institute where there was no movement, and the sound was neat and harsh, which made Chen Xiao can't help but think of something bad.

"Such a heavy grinding sound? Is it another mutation? ”

Chen Xiao's hunch has always been very accurate, especially at this critical juncture, when it is unfavorable to him, it is the most accurate.

The sound came from the room at the end, and the voices inside were getting louder and louder, and a pair of bright red eyes appeared, getting closer and closer.

After the things in the room came out, Chen Xiao realized what it was, it was a monster with a rat head and a human body, the upper body was the head of a mouse, and the lower body was a human body, which looked extremely weird, and there was a trace of disobedience.

The sound of grinding teeth was the sound of the rat's head, and Chen Xiao didn't know what kind of monster it was, only that this thing was definitely not a mutant, but a transformed human monster made by the black crow.

"Alas, it's really self-inflicted, it seems that these people don't know until they die, and this will be the result of joining the crows..."

Chen Xiao shook his head, the black crow used the slogan of making them stronger, gathered some people who did not have a sense of crisis, and then those who did not evolve into abilities used them as experiments to do all kinds of strange and terrifying experiments.

He had seen such poor monsters more than once, and to be honest, when he saw these monsters, his first reaction was not fear or fear, nor did he immediately put on an attacking stance, but was full of pity.

However, this does not change their current appearance, even the healers of the bull batch cannot turn them back into human beings, they can only survive in this world under the name of monsters for the rest of their lives.

If they are still conscious.

The rat crowd had already come to Chen Xiao, and Chen Xiao finally saw their whole body clearly, in addition to the rat-headed human body, their arms were also very different from humans, and the five fingers were all fitted with slender steel needles, like sharp claws.

In addition to this weapon, their teeth are also very sharp, the length of which has protruded from their mouths, and a bite from them could cost them half their lives.

The rats also seemed to see Chen Xiao and began to rush towards him in a swarm.

Of course, Chen Xiao couldn't stand stupidly and be attacked by them, so he hurriedly changed his armor form, and as soon as he opened his arm knife, he stabbed a rat head and killed him happily.

I don't know how long it took to fight, but the ground was already full of monster corpses, basically all of them cut their throats with a knife, and the corpses were separated, and they were exactly the same.

Chen Xiao also seemed to be a little tired, but the rats were still walking out, which also made Chen Xiao start to wonder, what kind of place was there? You can't run into some lair by mistake, right?

"I can't spend it with them anymore..."Chen Xiao cut off a rat's head with another knife. If I continue to consume like this, I'm afraid I'm going to be consumed here! ”

Since he didn't know the number of rats, Chen Xiao could only venture to that room to have a look, the double knives in his hands accelerated violently, and the speed of killing monsters also accelerated a lot, and he came to the front of the room after a while.

Although there were still strange things inside, Chen Xiao suddenly jumped, flew into the air, flew against the roof, and came all the way to the depths of the room.

The room was pitch black, but what could be seen was that the red eyes were coming out of the center of the room, and they were spiraling out in all directions.

Chen Xiao slowly took out the lighter from his arms, this lighter was still the one that Lao Qin gave him at that time.

"It's been so long with you, it's finally time to burn you to the last moment..."Chen Xiao quickly lit the fire and threw the lighter towards the center of the room.

When the lighter fell to the ground, the flames increased rapidly, and the whole room was lit up at once.

And the things in the room were also at a glance, but the scene here surprised Chen Xiao.

"What is this?!"

There was a huge device in the room, and in the middle was a large transparent jar, which contained a large mutant rat, whose body was already a little white, and it looked like it had been soaked for a long time.

Around the jar, there are small pipes connected to the small jars around them, and in the jars are unconscious human beings.

Chen Xiao finally realized what kind of device this was, this is a real-time human-transforming system, through the connection of the switchboard and the sub-machine, the human and mutant rats are combined together.

And the lighter that Chen Xiao threw just now happened to be thrown into the big jar in the middle, which instantly detonated the liquid in the jar and lit up the room.

As the middle jar broke, the small jars also shattered, and the people inside were lying on the ground, but it seemed that they had all lost their vital signs, that is, they were all dead.

This also means that those rat people outside may not be living creatures, just some puppets.

Since the device that provided the transformation of people was destroyed, and the number of rat people was not increasing, Chen Xiao did not need to stay in the air anymore, and quickly fell to the ground, solved some of the remaining rat people, and thought about resting for a while.

But at this moment, there was a sudden noise outside, Chen Xiao hurriedly stood up, came to the door, and listened attentively to what sounds were outside.
