The system is the king of the counterattack master

Seeing that the situation is not optimistic, Duanmuxiu came up with an idea: "Otherwise, let's smash down the next wall, let the black energy disperse and gather in this place, that's not the way."

Han Xiaodong glanced at him and shook his head: "The walls here are all made of cement. Unless we get an excavator, we can't do anything about it. This plan won't work."

Duan Muxiu was silent when he said that, so he heard He Xi say again: "Why don't we try wearing a gas mask, our gas mask is professional, and this black air should be able to resist it." Can you live?"

Han Xiaodong thought for a while, this is indeed a solution, but he doesn't know what kind of substance is in this cloud of black air. Judging from the changes after they entered He Xi's body, these things seem to be extremely dense. He is not afraid of anything else, just I am afraid that these things are large particles, and when the time comes to block the air intake of the gas mask, it will be troublesome. Not to mention the use of the gas mask, they will also be in danger.

Before he could speak, Duan Muxiu expressed his opinion first: "I don't think so, look at this cloud of black air floating in the air like this, it's not scientific at all, maybe it's some sorcery, just in case anti-virus The mask can't bear it, so let's explain it all."

He Xi's plan was denied, and he had no choice but to mutter to himself, "Don't we just have to give up?"

The three of them all understood that from the footprints in front of this room, this is probably where Zhou Hao and Xueqing entered. If they go any further, they probably won't find anything new. Joining will not be able to break through this layer of blackness. Then they can only go home.

Just as Han Xiaodong was thinking, He Xi's walkie-talkie rang suddenly. After the three of them went underground, He Xi's walkie-talkie was always on. This was the contact signal for Gao Hui and the others. Check the time, it has already passed It's been an hour, and they reported their safety to the higher-ups, and they didn't say anything more to the two of them. The most urgent thing now is to break through this difficulty.

Han Xiaodong looked at the flashlight repeatedly shining into the black air several times, but he didn't know what to do, so he had to ask K for help: "Is there any way?"

"No." K replied simply.

Han Xiaodong was speechless, thinking that this bastard spoke directly, and blocked all the roads at once. If even he can't do anything, I'm afraid there is really nothing to do this time.

Just when he was worried, Duan Muxiu's complaint came from his ears:

"I'm still wondering, with such a ghost thing blocking our way, how did Xueqing get out by herself? Don't tell me there is a portal inside. If that's the case, let's just pass it in from above, okay? If there is no door Could it be that Xueqing wanted to die in love with Zhou Hao here? I really can't understand this kind of romance."

Listening to Duanmuxiu's rambling, Han Xiaodong also felt that something was really wrong. If Xueqing did it on purpose, then she must have a way to solve it. If Xueqing didn't do it on purpose, then she most likely did it. What kind of accident happened there, because among these few people, it is certain that Xueqing is the one who knows the most about this place.

Reconnecting all the things in his mind, Han Xiaodong suddenly had an idea. He thought of He Xi's reaction just now. After these things entered her mouth, they instantly blocked her respiratory system, and some even became solid, that is to say, the gas seems to have chemically reacted with something in the mouth, so it changed form.

What kind of chemistry in the oral cavity can have such a direct reaction with substances?I'm afraid there's only saliva left!

Thinking of this, Han Xiaodong turned around and ran back to the corner where He Xi was being treated just now. Duanmuxiu and He Xi were taken aback when they saw this, but they immediately realized that Han Xiaodong must have discovered something, and hurriedly followed him back to the corner.

The two of them were not as fast as Han Xiaodong, and when they reached the corner, they saw Han Xiaodong pinch a small amount of black liquid with his hands, put it to his nose and smell it.

Seeing this scene, Duan Muxiu almost vomited, turned his head to the side and said, "Damn, what are you doing! This is too disgusting, don't you want to relive the taste of this stuff? "

As soon as he finished speaking, He Xi slapped him on the head, which made him scream.

He Xi leaned down, squatted beside Han Xiaodong, covered her nose lightly and asked, "Did you find anything?"

"Sugar." Han Xiaodong said without thinking.

"Sugar? Are you crazy? Do you think this thing is sugar? Do you want me to get you some more boiling water, so you can make a cup to warm your stomach?" He Xi slapped Duanmuxiu and dared not answer back. I had no choice but to vent my anger on Han Xiaodong, talking non-stop.

"It's not that it's sugar." Han Xiaodong raised his hand and took a flashlight to shine a light on the black liquid that had been pulled out between his fingers: "This thing can react with saliva. Our saliva contains a lot of amylase, which can It uses this mechanism to convert the food we eat into sugar, and quickly converts the black air into a viscous substance similar to syrup, then paralyzes the muscles near the mouth, and then flows back into the trachea to block the respiratory system. cause death, so its principle is very similar to that of saliva making sugar"

Of course, this is not the result of his analysis, but the answer given by K through his contact. He is now K's hands and feet. If K wants to study something, he collects data through his senses.

However, the result of his analysis still stunned He Xi and Duanmuxiu. After all, there is no testing equipment here. It was dubious, but at this time, apart from believing in him, the two of them couldn't think of any better explanation for the time being.

"It's useless to just know the principle. We still have no choice but to take that thing. We can't spit around the black gas, right? When the black gas is cleaned up, I guess the three of us can only go with the gang of mummy gone."

What Duan Muxiu said is correct. If you just know the principle, there is nothing you can do about the black air, but Han Xiaodong naturally has his own calculations. He stood up, pointed to the end of the corridor and said: "Follow me, There's a storage room up front, and we've got what we need in there."

Neither He Xi nor Duan Muxiu understood what he meant, so they had to follow him all the way to the end of the corridor on this side.

There was indeed a very large storage room, the door had been knocked to the ground by Duan Muxiu long ago, after the three entered the storage room, Han Xiaodong walked straight towards a shelf.

Duanmuxiu scanned the storage room with his flashlight. There were all kinds of commonly used medicines and food. He really couldn't figure out what kind of treasure there would be to restrain the black energy.

Just as he checked these abandoned storage items with a flashlight, a cloud of dust instantly filled the entire room.

Duan Muxiu quickly covered her mouth and nose with her hand, pinched her nose and shouted: "What the hell are you doing? You're choking to death!"

But when he pointed the flashlight at Han Xiaodong, he was instantly attracted by the thing in front of him. It was a box full of normal saline!
