The system is the king of the counterattack master

Whenever possible, be fully prepared for the unexpected.

This was what K said to Han Xiaodong the most, and it was also the most annoying sentence he heard, but at this time, this sentence became his life-saving straw.

The moment Morse's brain left the ground with its last foot, a huge metal weight flew straight towards it.

Although this brain-shaped monster is hard enough, it can even be said that it is invulnerable, but when its entire body stays in the air, its light weight becomes its most fatal weakness.

The metal weight is nothing but a heavy metal container in the laboratory. This container is usually used to hold low-temperature reagents, because these reagents need to be stored in liquid nitrogen, so this container is not only large, but also strong enough .

After losing his body, the monster could no longer spit out red liquid. The only weapons he could use to attack were his hard body and sharp teeth.

When Han Xiaodong was doing the strong acid attack, he didn't release all the doubles, just to prevent this situation from happening.

The metal container was lifted by two stand-ins, and under the cover of thick smoke, it was thrown towards the monster.

The monster is not unaware of these doubles, but it has been completely irritated by Han Xiaodong at this moment, because it has fought with these doubles, so at this time it ignores the existence of these doubles just like it ignored the fantasy at that time. In its eyes, These things are not worth mentioning at all.

The biggest wish of this furious monster at the moment is to tear up the jumping up and down kid in front of him. It is because of him that he has fallen into the current situation.

But what he didn't expect was that in this backup plan, Han Xiaodong was the bait, and the real main attackers were those seemingly harmless substitutes.

The shape of the metal container was like a large vat. After flying high, it just held the monster in it impartially.

The moment the metal container fell to the ground, the covered monster roared inside. It desperately hit the tank wall, frantically trying to smash or overturn the thing on its head.

However, the reaction of the substitutes was not slow, they quickly fixed the large metal cylinder, and at the same time inserted a can of nitrogen gas into the connection on the cylinder body.

As a stand-in turned the valve, there was a bang, and a large amount of nitrogen was poured into the cylinder.

The floor of the laboratory is very flat, and the joints of the metal tank have no bumps, so the entire bottle of liquid nitrogen is almost completely poured into the metal tank.

The characteristics of liquid nitrogen can be said to be very special. Although it has an ultra-low temperature of minus 190 degrees, if it is only a short-term contact, it will not have any impact on living things, because the instantly vaporized nitrogen will freeze outside the object. Form a very thin ice shell to resist the low temperature.

However, the duration of this ice shell is also very short. Once it is in contact with liquid nitrogen for more than two seconds, it will cause frostbite to the creature. If it exceeds one minute, it will basically die.

After the liquid nitrogen was filled into the metal tank, the effect was produced quickly. When the monster encountered the liquid nitrogen, it became even more crazily agitated in it, as if it had experienced great pain. When Han Xiaodong saw that it was effective, he immediately asked the stand-in to put the second tank Liquid nitrogen was also filled in.

The monster hit the cylinder wall vigorously at first, but soon, the sound of the impact turned into a slap, and after about 2 minutes, the sound finally disappeared.

After a fierce battle, Han Xiaodong finally heaved a sigh of relief. The avatars were still holding the metal cylinder firmly. Han Xiaodong took a look, and really didn't want to have anything to do with that thing, so he simply asked the avatars to maintain this position, anyway. He believed that no one would come here again, so he thought of simply throwing the monster in here and just ignore it.

After dealing with the monsters, the next step is to find a way to leave this ghostly place. Han Xiaodong came back to the iron gate and studied for a long time before he found the mechanism of the gate. The design of the gate is very strong. Where the mechanism is, there is basically no chance of destroying it.

After he pushed the door open, he was about to walk outside, but the punishment in his head suddenly said: "Where are you going?"

"Go back to the top, I still have to find a way to save Duanmuxiu. After this trip, although I killed Morse, the problem in front of me hasn't been solved yet. It's a big head."

Han Xiaodong sighed. It stands to reason that Morse was his father-killing enemy, and he should be happy that the revenge he had held back for more than a year was avenged today, but for some reason, he just couldn't be happy.

He always felt that killing a monster with a narrow escape was really not considered revenge for his father. As for the deeper things, he never thought about it. In short, he just felt that there was something worse.

Regardless of whether Morse in the metal vat is dead or not, Han Xiaodong no longer cares. Where does this indifference come from? He also feels very entangled. He just thinks that saving Duanmuxiu is the most important thing now. As for Morse, Let's talk about it later.

He attributed all this to the fact that Morse was just a monster responsible for execution, and the enemy he really wanted to deal with was actually the entire Ark organization.

Right now Duanmuxiu is in danger, he doesn't have more time to think about the ark, the priority is to save people first, so as soon as the gate is opened, he has to return to the ground.

"You can't go yet." Punishment said in his mind.

"Why?" Han Xiaodong asked puzzled.

"First, if you want to save Duanmuxiu, you can only find the antidote here. Second, there is something under that iron guy that you need to take out. Now that you are gone, you will regret it later."

I dare not say anything else, but in terms of mystery, Xing and K are like a pair of brothers, they never explain things clearly, they just give a rough idea, and then let you guess.

Fortunately, Han Xiaodong was already used to this way of communication, so he asked in a very uncomfortable mood: "Why is the antidote here? Besides, I don't know what kind of ghost virus is in Duanmuxiu, how can I prepare the antidote? Don't go around the bush, just speak up."

Regarding Han Xiaodong's almost challenge question, the punishment was not angry at all, but said seriously: "I have already handed over the virus to you, but you still need a carrier to get it out, you go out now, and you have to come back again later." , I don’t suggest you make this trouble for yourself.”

Hearing that the punishment said that the virus had already been handed over to him, Han Xiaodong was taken aback for a moment, and then he remembered what happened in that room just now. At that time, the punishment asked him to open the safe. There were indeed two things in it, one was for Morse. That dagger, and the other, was a metal test tube.

"Are you talking about it?" Han Xiaodong stretched out his hand and took out the test tube from his arms. He really didn't expect that such a dangerous thing, punishment would let him carry it on him so hastily. Carefully broke the test tube... Thinking of this, Han Xiaodong broke out in cold sweat.
