They all know that there are usually such signs, and they are generally very dangerous inside, and there are certain radioactive materials.

Chen Xiao thought of the pungent smell before, and couldn't help but worry in his heart.

"The smell isn't contagious, is it?"

However, after a long time, my body did not have any adverse reactions, and it is estimated that there was no effect.

On the contrary, Zheng Ling reacted very much, and kept yelling at the door, if it weren't for Lao Qin pulling her by the side, maybe she wouldn't know where she could run.

"Brother Chen, think of a way! What's wrong with my wife? Lao Qin said anxiously.

"Take a cloth and cover her mouth and nose, I guess the smell is irritating her."

"I knew I would have left her on it."

Lao Qin sighed, tore off a long strip of cloth from his body, and tied it to Zheng Ling's face at the same time.

Suddenly, Zheng Ling regained his composure and sat down on the ground.

It is estimated that it is due to physical exhaustion, or it may be due to prolonged emotional tension.

Chen Xiao couldn't help but feel distressed when he saw this scene, and said softly.

"Why don't you take care of your sister-in-law here first, and Xiao Hei and I will go to the front to explore the way first."

Lao Qin nodded, it seemed that he still couldn't rest assured of his wife.

However, Chen Xiao can also understand, just like he is also very worried about his daughter at the moment.

Lao Qinhe helped Zheng Ling to the side and sat down, while Chen Xiao and Xiao Hei gently pushed open the door and walked in.

There is a lot of space in the factory, and you can vaguely smell a strange smell, which is not the rancid smell in the previous passage, but the smell of some chemical waste.

But fortunately, I didn't have any malignant reactions, and it would be worth the loss if I didn't let it.

There was a lot of water on the ground of the factory, but Chen Xiao couldn't find where it came from.

"Tick-tock, tick-tock..."

In this quiet factory, there was a clear sound of water dripping, and following the sound, Chen Xiao saw that above this factory, there were several large water buckets, which were also painted with the yellow logo.

Underneath the bucket, there is a cistern filled with an unknown yellow liquid, from which the strange smell emanates.

Chen Xiao slowly came to the cistern, squatted on it, and held a torch to shine on the surface of the water to see if he could see what kind of liquid it was.

However, when he put the torch on it, Chen Xiao was directly frightened and turned over, and in this cistern, there was a whole pool of corpses.

"I kind of know why there is so much water in this place, it's because it's too full."

Chen Xiao eased his mind, stood up, and began to observe carefully.

And Xiao Hei threw up again.

Chen Xiao took out the knife he was carrying, picked out a corpse from it, and began to study it carefully.

"Judging by the decomposition of this corpse, it must have been dead for more than a month, who left them here?"

Chen Xiao took the knife, stabbed it left, inserted it right, and finally the tip of the knife rested on a sign on his clothes.

"Isn't this the uniform of our research institute?"

Chen Xiao suddenly realized that although the body itself was highly decomposed, the marks on his clothes could still be seen faintly.

That's an obvious new word, in Chen Xiao's biological science research institute, all the employees have a uniform like this, but he doesn't know who this is?

Chen Xiao began to search frantically, hoping to find a trace of the dead body.

However, after looking for a long time, Chen Xiao only found a fragment of a business card in the pocket of this clothes, with only one Zhao character on it.

"Could it be Professor Zhao?"

Chen Xiao didn't want to believe that this person was Professor Zhao, but his body was extremely rotten, and he couldn't tell who this person was.

However, according to various indications, there is no doubt that this person is Professor Zhao, at least Chen Xiao has confirmed this fact.

Just when Chen Xiao temporarily stayed in the grief of losing his teacher, the corpse in front of him suddenly shook, which frightened Chen Xiao again.

And Xiao Hei, who came back after spitting up, also looked confused, covered his mouth and asked.

"I'm going, what's the situation? Is it a corpse? ”

The two quickly jumped away from the corpse and stared at it.

"It stands to reason that a corpse that has been dead for so long will not be easily raised, could it be that we have brought the breath of the living? That's why he got his body up? Chen Xiao muttered to himself.

Regardless of the reason for the moment, I saw that the vibration of the dead body became stronger and stronger, and finally his stomach suddenly became bigger and bigger, and finally burst.

And a black shadow sprang out from inside, heading straight for Xiao Hei.

Where had Xiao Hei seen this kind of formation, he was so frightened that he grabbed the black shadow with both hands, and at the same time kept screaming.

"Ah!!h

And Chen Xiao quickly ran to Xiao Hei's side and also saw the thing in his hand.

It was a mouse, but it was still slightly larger than a normal mouse, and its eyes were red, and it should have been a species that had been mutated.

However, since it was in the teacher's belly, it meant that there was something inside his corpse that the mutant rat needed.

And most likely, perhaps, nutrition.

After the human body dies, the nutrients in the body will be retained for a period of time, and only when the body decays to a certain extent, the nutrients will be lost, and this mutant rat is likely to take a fancy to the residual energy in this corpse.

Since there is a mutant rat in Professor Zhao's corpse, the other corpses in the cistern...

Chen Xiao slowly tilted his head and looked at the cistern next to him.

Something happened that he didn't want to see.

The cistern suddenly began to react violently, and gurgling bubbles came out of it, and after a while, it began to backfire on a large scale.

Seeing this situation, Chen Xiao hurriedly slapped away the mutant rat in Xiao Hei's hand and pulled him outside.

However, the violent reaction of the reservoir also caused the entire chemical plant to shake violently, and the passage at the entrance of the chemical plant has now completely collapsed, blocking the only way out.

"Damn, look at me!"

Chen Xiao quickly conjured out his armor and punched hard, but he could only smash a small hole.

"Boss, no, it looks like this passage has collapsed more than a little, and we can't get out of here!"

Chen Xiao's eyes were like torches, and he frantically swept the surrounding environment, but he didn't find any other way out.

The reservoir was shaking violently, and countless mutant rats were gushing out of it.

The number of them quickly occupied the ground of the chemical plant, and Chen Xiao and Xiao Hei were also their only targets for gathering fire.

Chen Xiao didn't care too much, after all, he had armor to protect himself, but Xiao Hei was different, although he also had zombie blood, but now he was just a partial auxiliary growth ability, and he couldn't withstand the fire attack of so many mutant rats.

Seeing that Xiao Hei was exhausted, Chen Xiao was also very worried, resisting the attack of the mutant rat while observing the way to escape, and at this moment, he thought of a place.

"Blackie! Get on the bucket! ”

Xiao Hei glanced up, comprehended, and immediately rushed towards the reservoir above the center of the chemical plant, and Chen Xiao also jumped violently, using his floating ability to come to the reservoir.

"Quick! Blackie, grab my hand! ”

Xiao Hei does not have the same strong physical fitness as Chen Xiao, after all, he is still young, and after many attempts, he has not been able to reach Chen Xiao's hand.

Seeing that there were more and more wounds on Xiao Hei's body, Chen Xiao was thinking frantically in his mind to see if there was a perfect solution.

"Is there a way to get rid of these rats?"

Chen Xiao frantically rummaged through his pockets, and what he found at the end also made him feel pleasantly surprised.

"It's... Match?! That's right, with fire! ”

Chen Xiao turned out a box of matches that Lao Qin gave him before, and at this time, he thought that rats, animals, were afraid of fire, and even if he was mutated, he couldn't change his natural habits.

Chen Xiao took out a handful of matches from the matchbox, lit them all, and at the same time took off his clothes, led the flames to his clothes, and then jumped off the cistern and came to Xiao Hei's side.

At this time, Xiao Hei was already scarred, and it seemed that the lethality of these mad rats was indeed not small, and with such a number of mutant rats, perhaps only elemental abilities could fight with them.

"Blackie! Are you okay! Can you still hold on?! ”
