The system is the king of the counterattack master

After spending a lot of effort to climb down the watchtower with one arm, Han Xiaodong started to head towards the entrance of the city. According to K, those monsters did not come to trouble him.

Most likely, after knowing that he was infected, the monsters had already regarded him as a mutating kind. Although it was unknown when this misunderstanding would be noticed, it did reduce his danger a lot.

On the way out of the town, Han Xiaodong kept complaining about K’s barbaric way of charcoal roasting him, while K simply ignored him and kept talking about the mutation mechanism of these microorganisms. The two of them just talked to each other and returned to the cliff at the entrance of the town. .

Although it was inconvenient to use one arm, Han Xiaodong still had the help of his skills. After erecting an ice ladder, he smoothly got into the passageway when he came here. Natural caves for stumps.

In fact, from the moment he entered the town, there was always a question in his mind. The two ends of the passage were connected to the town on one side and the natural cave where he was located on the other. It will have a great impact on the diffusion of gas, but in this cave and outside the cave, there is no obvious fog.

If it is said that the green mist will not erode this cave, then the dead people inside and outside the cave cannot explain it. Obviously, there was indeed a green mist erosion in this cave before, and it killed the expedition team, but now the mist has not come over. Myself, this is puzzling.

What's even more strange is that there are the remains of the expedition team outside the cave, but there are only some stumps that failed to mutate in the cave. If he didn't see the monsters in the town, Han Xiaodong could attribute this to the failure of mutation, but the situation in the town is different. Proven.

Regardless of whether the mutation is successful or not, unless they are killed, these microorganisms will definitely become some kind of living body, not a puddle of mud. This contradictory situation is completely unreasonable.

In this cave, what happened in the end, now it seems that it has become a difficult mystery.

Regarding Han Xiaodong's question, K did not give any usable clues. He just asked him to find a corner to sit down first. After testing the air quality, he finally changed the defensive state of the air shield.

The moment the fresh air from the cave rushed into Han Xiaodong's throat, he felt extremely refreshed. After taking three deep breaths, he finally felt that the wounds on his body had begun to heal. Obviously, K had also begun to work.

"Do you think the air here is a bit weird?" Han Xiaodong took a breath and smacked his lips, as if tasting the smell in the air.

"What's weird? I don't feel it." K was a little baffled by his question.

"You sort out my taste data, why do I feel that the air in this cave is a bit salty." Han Xiaodong licked his lips, still feeling a bit strange in his mouth.

K didn't reply, and after waiting for a while, he said in confusion: "There is really a problem, it seems that you are not useless at all."

For this evaluation, Han Xiaodong was also speechless, and it didn't sound like a compliment.

Fortunately, his current concern is not here. Hearing that there is indeed a problem with the air, he hurriedly asked: "What is the reason? Isn't there a problem with the air?"

"My test only screened specific microorganisms in the air, and no danger was detected, but from your senses, there are other things in the air, maybe these things inhibit the spread of microorganisms, I need to re-analyze the air composition, I need you to do me a favor." K said, and drew out a list, which contained some experimental equipment and inspection procedures.

Han Xiaodong didn't dare to neglect. Although the shoulder injury was still causing him pain, it was still possible for him to set up an experimental environment.

From collecting air samples, to compressing, separating, and re-collecting the colloid on the ground, and doing various testing experiments, it took more than an hour. Han Xiaodong wiped the sweat from his head and put down the test equipment in his hand .

"There is still a big trouble outside. We are here to give the experimental class. It's really big." Han Xiaodong took off his gloves and sat down on the ground. Although the wound healed, it was a serious injury after all. Not that fast.

He is only in charge of the operation, and the specific data is collected by K, so all he can do now is to hide and recover his strength, and wait for the results to come out.

"Stop complaining, I think we have made an accidental discovery, and this discovery is enough for you to win this year's Nobel Prize in Biology." K said leisurely.

For the previous data, Han Xiaodong directly stuffed the samples into the Wanbao bag, and K operated it himself. Although this kind of experiment is quick and easy, in terms of the effect, it cannot reach a [-]% perfect conclusion.

However, this method is simple, fast, and sufficient, so neither of them is too fussy.

But this time, with the cooperation of two people, a complete experiment was done, and the data obtained by K was naturally more perfect.

"Let's talk about it, and then I'll go talk to Nobel and see if he's willing to give me that award." Han Xiaodong doesn't care about any new discoveries now.

All he cared about was how to deal with that damned mummy, that guy had extremely rich fighting experience, just like an excellent chess player, he could even make his opponent play cards according to his own routine.

"The air in this cave contains a substance that I have never seen before, which can inhibit the evolution of microorganisms.

No, to be precise, this substance can inhibit the evolution process of all life, so after the microorganisms invaded the expedition team here, they did not complete the evolution and died directly.

The infected people we met outside have not even entered the evolutionary stage, this substance is simply the natural nemesis of those green mist! "

K spoke excitedly, but hearing Han Xiaodong's ears, his face turned pale: "So, if you found out earlier, I just needed to run into this hole to stop the evolution, that is to say, I Is the fire on my body considered to be in vain?"

Hearing Han Xiaodong's bad tone, K quickly explained: "No, no, you misunderstood, this kind of gas can only be prevented if used in large doses in advance, and the current gas density in the cave will only make evolution fail, but the green mist It will still kill the host, and the overall process will not be affected."

After hearing this, Han Xiaodong sat on the ground slumped, and said listlessly: "Doesn't this mean that nothing was discovered? Anyway, they are all dead, so why should they be punished twice?"

As he spoke, his eyes turned to the stumped limbs on the ground. If he had to choose, he would rather become a monster than become such a puddle of mud.

"Or else, you can only see the immediate benefits. If you don't think about it, the microorganisms in the green mist come from the world of singularity, so it just so happens that at the exit of the channel where they can overflow, there are The emergence of environments that specifically inhibit their evolution? Is this just a coincidence?"

K's reminder made Han Xiaodong realize the problem at once. He blinked his eyes, hesitated for a long time, and then murmured:
"You mean, this suppressive environment is artificially created?"
