Yun Xin's upper body had already drilled into the exhaust channel, and due to the blind spot, she couldn't see that the monster had grabbed her feet.

She was ready to drill into the exhaust tunnel in one go.

She used her hands together, struggling to crawl towards the exhaust channel, kicking her legs back and forth.

This kick doesn't matter, this kick, Yun Xin found that she had kicked something, and this kick made her feet powerful, and she suddenly climbed into the exhaust channel.

"Whew......"

The monster covered its blood-red eyes, screamed, and fell to the ground.

It turned out that Yun Xin's kick hit the monster's eye.

Yun Xin was in the exhaust tunnel, couldn't see the room situation, and didn't know what was going on.

She didn't dare to stay long, she remembered that there was a laboratory on this floor, there were a lot of chemicals in it, and she was going to borrow chemicals to deal with monsters.

It's just that she just climbed halfway up, and with a "bang", a fist hit her underneath, and the board turned up, making Yun Xin get up in fright, and with another "bang", her head hit the top of the exhaust channel.

Because of the suddenness of getting up and the force of the impact, Yun Xin's painful tears were about to come out.

Ignoring the pain, Yun Xin hurriedly crawled towards the front of the exhaust channel, hoping to crawl out of this room as soon as possible, but he didn't want to, the monster also persevered, and wherever there was a sound, his fist would smash wherever it struck.

Yun Xin couldn't wait to show up and fight with that monster at this time, but his strength didn't allow it.

Finally, Yun Xin endured the pain while crawling to the turn of the exhaust channel, and as soon as she turned, she should be out of the room.

"Whew~"

The monster yelled as he pounded the exhaust channel.

Without the monster's hindrance, Yun Xin crawled much smoother, and she followed the exhaust channel, crawling around, looking for the laboratory where the chemicals were placed.

It wasn't until she climbed a few rooms that she found the lab.

She opened the lid of the exhaust duct, cautiously jumped into the room, and began to search the table for the alcohol and sulfuric acid she wanted.

Seeing these chemicals, Yun Xin couldn't help but lie in his heart, because none of them were written in Chinese, and they were all represented by chemical symbols.

However, what is the chemical symbol of alcohol and sulfuric acid?

Yun Xin really couldn't think of it, she directly opened the lids of these chemicals, this operation is very dangerous, but Yun Xin can't take care of it, her life is almost gone, and she is afraid of any danger.

About more than half of the time it was opened, Yun Xin didn't find what she was looking for.

Suddenly, the monster slammed the door of the laboratory open with a punch, and when he saw Yun Xin, he screamed, as if excited and angry.

Damn, come so fast!

Yun Xin saw the monster rushing over, and he was so frightened that he directly flipped the table.

A table of bottles and cans was smashed towards the monster.

Perhaps because while in the observation room, the monster realized that what Yun Xin threw was no threat to him, so he didn't hide this time.

What's more, he directly reached out and smashed those bottles and cans, and after falling to the ground, he also stepped on them directly.

Yun Xin spared his life, hurriedly put on a mask, and then hid aside.

The monster had barely taken a few steps before stopping.

He raised his hand, which was smoking, and seemed to be in pain......

Not only his hands, but other parts of his body were also smoking, and it was also painful......

He looked at the liquid all over the ground suspiciously, and then looked at Yun Xin.

"Ahh

The woman hurt him, and he was going to tear her apart.

Yun Xin saw that this monster rushed over desperately, and his brain suddenly calmed down a lot.

This means that people are going to die, and people are going to calm down.

There are many chemicals that produce a chemical reaction when exposed to fire, and with the help of accelerants such as oxygen, they can produce violent explosions.

There are a lot of chemicals mixed together, so if you set them on fire.

Yun Xin looked at the disgusting monster, rather than being bitten by him, it was better to die together.

Yun Xin didn't hesitate, she raised her right hand, and a small fireball suddenly appeared.

She smiled slightly, and then threw the small fireball at him under the gaze of the monster's blood-red eyes.

The small fireball didn't seem to be threatening, so the monster didn't dodge.

Yun Xin threw countless small fireballs in succession, some on the monster, some on the ground full of chemical liquid.

The fire met those chemical liquids, and suddenly, with a "bang", exploded.

A heat wave hit.

"Woo woo ~ " the monster screamed.

"Ahhhh

The explosion did not stop, and the chemicals in the other cabinets in the room exploded in the face of fire and high temperatures, and the raging fire did not go out.
