Steel Fist finally chased Yu Changsheng.

Yu Changsheng was facing away from him, trying his best to suppress the surging evil energy in his body, and his body was constantly trembling.

Steel Fist gasped and said in surprise:

"Strange, why are all the bodies here?"

Yu Changsheng was slightly stunned, he didn't expect this guy to catch up with him so quickly, fortunately, the yellow smoke here was still relatively thick, otherwise he would definitely have found out when he devoured the last fierce rubber demon just now.

"I don't know, leave the corpse alone, look here......"

Yu Changsheng said, pointing forward.

In the hazy yellow smoke, a staircase appeared.

Steel Fist was slightly stunned, looking confused.

"No, I've been looking here for a long time just now, and I didn't see this staircase at all."

"The corpse of the demonic beast you mentioned has not been found, it should be that the structure here can also change over time, and maybe even according to the way we move, so it shouldn't be a good idea to stop here." Yu Changsheng lied indifferently.

Steel Fist frowned, glanced back, looked at the building again, and said:

"Well, I'll leave a special mark here, and if they find it, they can follow the mark to find us!"

As he spoke, the steel fist began to paint the ground with some kind of special paint.

Yu Changsheng was still fighting against the negative consciousness generated by evil energy in his heart, and he felt a little funny looking at the current action of Steel Fist.

After the steel fist was applied, the two of them climbed up the stairs one after the other.

The steps of the building here are very high, and when the two of them came up, they realized that the entire building should have been a four-story building before it collapsed, and the location they were now in was the basement. This staircase leads in one direction to the third floor, and there is no access to the first and second floors from here.

The two kept climbing up, and soon reached the third floor.

Stepping on the staircase, I found that the entire third floor has been filled with a lot of smoke, and I can't see my fingers, the intensity of this smoke is obviously far greater than that of the underground floor, and the visibility is not even half a meter, but the power system on this floor seems to be intact, and there are still a few magnetoelectric emergency lights in the corridor.

The smoke was too thick, and the fire stone of the steel fist could no longer play a role, and the direction could only be vaguely judged by the light points in the distance.

Although Yu Changsheng loves to smoke, it is still difficult to accept this strange smoke, the smoke has penetrated into the respiratory tract through the mask, Yu Changsheng tried to fan this haze with his hand, but it was useless.

This kind of yellow smoke has a strong irritation, making Yu Changsheng feel as if his throat is constantly poked by small steel thorns, drawing out a bloody mouth, and then spreading along the bloody mouth with bursts of pain, but this pain is quickly absorbed by the evil energy, and the wound is very small, and the recovery speed is also very fast.

"The smoke is too thick, do you want to keep going?" Yu Changsheng asked.

"When you put the cigarette in your mask just now, you didn't see you say that the smoke was thick...... Don't worry, I know what this yellow smoke is, for us, this gas will only make the throat a little uncomfortable, and the poor immunity may have a slight effect on the capillaries, but this smoke is different for Warcraft......"

Steel Fist paused, and looked around with some vigilance, as if he wanted to tell the secret, but he was afraid that the rest of the team would hear it.

"What is it?" Yu Changsheng asked.

"It's the berserk factor, this yellow smoke is full of the berserk factor, once ingested, it will make the demonic beast crazy and killing, and the desire to fight will be even stronger."

"Oh? I also know a little about Warcraft, and I've never heard of this magical smoke, how can you know so well? ”

"Because I'm in one of the three schools that specializes in Warcraft. These monsters we encounter are called Fierce Rubber Demons, and they have a strong ability to resist attacks and adapt, so they have been secretly cultivated by the military for a long time and used as training tools for the army. And this yellow smoke is called Angre. The raw materials of Angrui are very simple and cheap, and by adjusting the concentration of Angrui, the combat effectiveness of the Fierce Rubber Demon can be controlled, so the venues that generally use the Fierce Rubber Devil as training equipment are also equipped with Angre's storage tanks. ”

"I see, the Empire's training methods are really unique." Yu Changsheng said, already taking off his mask.

Since these yellow smoke can't kill him, Yu Changsheng feels that there is no need to continue wearing this mask, and the sieve hole on this mask is almost filled with yellow smoke and dust.

"Unique? Hehe, there are more unique ones, and you will understand them when you get to Sansu. Steel Fist said.

"Not interested."

Yu Changsheng said, pulling the lighter, and there was another strange smoke in the smoke.

The two of them were about to step into the corridor from the stairwell, when suddenly, Steel Fist looked around vigilantly while pressing down on Yu Changsheng's shoulder.

Even if he didn't do this, Yu Changsheng wouldn't move, because he also felt something strange around him.

"There are those guys on this floor......"

"That's right."

The steel fist tentatively moved a few steps forward and made a silent gesture to Yu Changsheng.

Yu Changsheng held his breath and listened, there was indeed a strange sound around, this sound was not far away, it should be within ten meters at the moment, there were at least three huge guys squirming here, their sticky bodies rubbing against the ground and making a stingy and slippery sound, making people feel as if there was a hook scratching in their hearts.

Yu Changsheng suppressed his breath and waited for the enemy to approach.

According to Steel Fist, Angrui will greatly increase the combat power of the Fierce Rubber Demon, so Yu Changsheng must strike more accurately and quickly, so that he can quickly kill the enemy.

The sound of squirming kept approaching, and Yu Changsheng found that the expression on the face of the steel fist became a little nervous.

It seems that these three fierce rubber demons are really more difficult to deal with.

It didn't take long for the Fierce Rubber Demon, who was getting closer, to smell their breath and approach the two of them.

Time seemed to stand still in this moment.

With a sudden tyrannical roar, the brief silence around them was instantly broken, and three violent fierce rubber demons rushed towards the two of them at the same time, and Yu Changsheng was shocked when he looked at their terrifying bodies.

In the bodies of the three fierce rubber demons who pounced, several soldiers who had been eaten could be clearly seen, their bloody heads staring in the same direction in despair before they died, their bodies already shattered, churning and rolling in the slime.

The figures of these three fierce rubber demons were larger than the one that Yu Changsheng had encountered, and they actually held the unique black iron thorn battle of the imperial soldiers in their hands. This is a secondary weapon that is standard for the Imperial Army, this weapon resembles a cane, but with a switch in the armrest that fires three narcotic ammunition.

Needless to say, these weapons must have been snatched from the dead by the fierce glue demons.

"You go up first, help me delay!" Yu Changsheng said.

"Why?" Steel Fist turned out to be dissatisfied.

"Of course it's because you're strong!" Yu Changsheng took a cigarette in his mouth and made a gesture of please.

Steel Fist glared at Yu Changsheng angrily, considering that the enemy was approaching, and now he was really going to go on the head.

"Come on, you dead fats!"

The steel fist shouted angrily, and instantly jumped up from the ground.
