Because of the poisonous gas, Yang Hengrui had to hold his breath and concentrate, his brain was slightly dizzy because of the lack of oxygen, and the two people who rushed forward were wearing professional gas masks, which were not affected at all, and rushed over with a swinging stick.

While resisting the feeling of dizziness and dealing with the enemy's attacks, Yang Hengrui immediately seemed a little exhausted.

He barely blocked in front of him with his hand, and smashed down with a stick, making Yang Hengrui's forearm severely painful and numb, unable to move.

On the other side, another security guard waved the steel pipe at Mo Jian's calf, Mo Jian snorted softly, his face was pale, and he was pulled behind him by Yang Hengrui, and the steel pipe whistled down and smashed directly on Yang Hengrui's leg.

"Hiss......"

Gasping for air, Yang Hengrui's right leg bent suddenly, his body staggered, and he almost collapsed on the ground.

The pain brought him back to his cage, and he narrowed his eyes, lunged up, and kicked the security guard in the chest with a heavy kick.

Yang Hengrui used ten percent of his strength with this kick, and the security guard only felt that the oxygen in his chest was forcibly squeezed out by this kick, and his lungs were torn in pain, and the whole person soared up, hitting the railing behind him, and his body rebounded towards Yang Hengrui.

Yang Hengrui's fist was like a rainstorm pear blossom, venting on this person's chest, and immediately made him lose his combat effectiveness.

He grabbed the security guard in the face, put the gas mask in his hand, and with a gentle push, let the security guard out of his side.

The security guard lost his gas mask, subconsciously gasped, all the yellow-green poisonous gas poured into his body, his eyes were as wide as copper bells, his eyes were full of disbelief, his hands clasped his collar, foaming at the mouth, and fell to the ground convulsively.

At this time, the oxygen in Yang Hengrui's body had dropped to a very low level, he was dizzy, he felt that the scene in front of him was rotating, and seeing the last security guard rushing over with a throwing stick on him, Yang Hengru hurriedly shook his head and put the gas mask on his face.

A breath of fresh oxygen diffused, Yang Hengrui seemed to be a person who was almost dead of water in the desert and had been suffering from nectar for a long time, he took two deep breaths greedily, and immediately regained his strength.

The throwing stick quickly enlarged in front of him, Yang Hengrui's body bent, blocking this person's arm, and hammered heavily on the crook of his arm, this person's arm was sore, and the throwing stick fell down directly.

And Yang Hengrui was about to pursue, but this person suddenly seemed to be crazy, and hit Yang Hengrui's head with his head, Yang Hengrui was afraid that his gas mask would be damaged, and he was about to take off the mask, and before he could defend himself, he was hit in the face by the hard gas mask.

The sharp pain hit, and the blood flowed down the bridge of his nose, and Yang Hengrui was sure that there were a few more cuts on his face.

"This person is sick, if my handsome face is affected, I can't continue to pick up girls, and I can't afford to sell you!"

Secretly muttered in his heart, Yang Hengrui stomped on the toes of this person, the so-called five fingers connected to the heart, the tearing pain made him immediately lose the strength to resist, Yang Hengrui wanted to take off his gas mask, but when he looked at it, he found that the gas mask had been shattered, and the small oxygen cylinders built in were broken.

Since there was no value of strength, Yang Hengrui didn't leave his hand anymore, one hand pulled the man's arm, a clean whip leg was thrown heavily on his face, and the crisp sound of bone shattering sounded, and the person howled miserably and fainted directly.

Knocking down all the enemies, Yang Hengrui immediately turned his head and was about to pull Mo Jian to escape, but he saw that Mo Jian's eyes were slightly closed, his body trembled slightly, and the whole person was a little delirious.

Yang Hengrui frowned, and when he put the gas mask on Mo Jian's face, the fresh air entered her lungs, and she was a little more sober.

She saw Yang Hengrui's face flushing through the gas mask, she kept holding her breath, and hurriedly said with concern: "You, don't give it to me, I can still insist, you can take two puffs yourself." ”

Yang Hengrui smiled bitterly, put the gas mask on his head, and took two deep breaths, only to find that the built-in oxygen cylinder had reached the warning line.

The security guard wore it all the way to fight with himself, I don't know how much oxygen was consumed, at this time the oxygen stock was already insufficient, Yang Hengrui said to Mo Jian quickly: "I don't care, my lung capacity has been the first in the school since junior high school, there is not much oxygen in it, it will only be used for you for a while, you follow me and go out quickly!"

"It's already covered in poison gas, and I can't stay long, listen to me, act now. ”

After Yang Hengrui finished speaking, he brought the gas mask back to Mo Jian's face, and immediately pulled Mo Jian to trot towards the road he came from.

When the two finally came to the sewage pipe, a closed iron gate appeared in front of them.

When they came, the iron gate was open, but now it was quietly closed, and there was no possibility of escape.

"Probably because they sounded the alarm, sealed the entire underground factory, and closed the gates...... What are we going to do now?"

Mo saw that through the gas mask, she hesitated a little anxiously in place, and seeing Yang Hengrui's brows furrowed, she subconsciously took off the gas mask on her face, wanting to give Yang Hengrui two breaths.

Yang Hengrui squeezed Mo Jian's hand quite strongly, didn't let her take off her gas mask, and shook his head at her.

There is only so much oxygen left, Mo Jian is afraid that one person is not enough, and if he takes two more sips, Mo Jian will definitely faint due to lack of oxygen at that time.

Mo saw that his eyes trembled slightly, and there were faint tears flickering.

At this critical juncture, Yang Hengrui suddenly saw a rotating gate on the thick pipe on the side, he ran over quickly, grabbed the gate, and slowly twisted it with all his strength.

As the gate operated, a rumbling hum sounded, the walls were constantly shaking, and the yellow-green poisonous gas gushing out of the pipe gradually became faint, and Yang Hengrui looked around and saw a ventilation window not far away.

At this time, the ventilation window had been closed by the louver fan, Yang Hengrui picked up the steel pipe on the ground, jumped up suddenly, and smashed a stick on the window.

The plastic louver fan burst open, the air circulating outside poured in, and the concentration of poisonous gas in the enclosed space instantly decreased a lot, Yang Hengrui tried to take a breath, although the poisonous gas still burned his lungs for a while, but he could still breathe a little.

"Hoo ......"

"It's a lot of fun now, don't see it...... We can't seem to get out of the fire for a while, sorry to bring you in. ”
