What Yan Huang said, Yi Chen couldn't refute it. At least in Xijing, the promotion of health boosters can be regarded as a success. Those who survive can face the reality, no matter what, it is better than Nanchuan, which has fallen on all fronts.

"My research institute has tracking statistics on the whereabouts of each bottle of booster, including the proportion of failures, the results of physical improvement after taking it, how many people have become infected because of it, and so on."

"Due to individual differences, the results of the improvement of the average person's body are different from high to low, but they are almost within a certain range. People who have taken strengthening agents can easily lift forty or fifty pounds of goods, and can run 800 meters at full speed without panting. Even those who wear glasses have a chance of regaining normal vision, while those with normal vision are no longer reinforced. In addition, there is no improvement in hearing, smell, etc., which is still different from that of infected people. ”

"In addition, they can easily kill four or five zombies around them, and even if they act alone, the chances of survival are very high. Unless it's a surprise attack at night while you're sleeping, other moments of the day are certainly no problem with self-preservation. ”

Yan Huang spoke vigorously and endlessly, and Yi Chen was also interested in this and listened carefully.

"Strengtheners have played a big role, but I don't think it should stop here, I need more special samples, like you, to develop more advanced potions. Because, zombies are also evolving. Yan Huang changed his words and pulled up his new discoveries in the second black rain.

"If the zombies infected by only one round of black rain are marked as the M1 stage, then the zombies infected by the second round of black rain are the M2 stage. And so on, maybe there will be M3 and M4 in the future...... We don't know what the future holds. ”

"The zombies in the M1 stage are the state of ordinary people after death, and their body shape will not change significantly. No matter how tall and strong a zombie was before he died, he remained the same after his decay and transformation, but his joints were not so agile. ”

"The M2 zombies are very different. On the one hand, they can become more manic; On the other hand, they are the enlarged version of the previous one, and their bodies are generally a head taller, and they are also prominent in physique, and their limbs are more developed. These changes have given them a big boost in speed, power, and bursts. If an ordinary person who has improved his physique through a body booster could have dealt with four or five M1 stage zombies, when he encounters M2 stage zombies, he may once return to the pre-liberation period. Yan Huang frowned slightly and said.

According to his observations, most of the M2 zombies will automatically explode and die after a short period of rage and glory. With their bodies, they can't withstand an overload of the virus.

Although the power is good, the uncontrollable power will only bring destruction.

Of course, there are a small number of M2 zombies left, and those are the best of the successful evolution. Black Rain will eliminate a batch of zombies that cannot evolve, and create a new batch of M1 zombies again. It's a terrifying survival of the fittest mechanic!

However, monsters don't seem to be in this elimination category.

Monsters are born to be the alien kings of zombies. A monster is far more terrifying than a group of ordinary zombies. They can evolve multiple times without limitations.

At the moment, the reason for the evolution of the monster is not clear enough.

Through observational studies and sharing and analysis with medical organizations in other regions, most of the theories gathered are that eating is the main reason for their evolution.

In areas with plenty of food, monsters generally evolve faster and better, on the contrary, where the population is poor, the strength of monsters will be relatively weak.

Weak monsters will be wiped out by humans, as well as by other monsters. Between them, too, there is a struggle for territory and resources.

In order to survive and develop, monsters will continue to attack the human base in order to improve themselves.

In addition to the problem of food sources, there may also be a sense of crisis.

In the face of adversity, people tend to burst out with unimaginable tenacity, and the same is true for monsters.

At a critical juncture, everyone will die and struggle, and the stimulation of potential will also make the monster go to the next level in a short period of time.

When Yi Chen left the Yanshi Industrial Medical Research Institute, it was already noon.

This time, he learned too much consultation and information from Yan Huang, and he needed to sort it out and settle it well.

As an infected person, what he did was not just in pursuit of wealth and profit. He keeps saying "conform to the market", but I am afraid that he does not want to admit that he is working for the confusing future of mankind. That's the awkwardness of his character.

Anyway, through this trip, Yi Chen learned that the other party's essence is not bad. Maybe Yan Huang may become a trustworthy teammate in the future, but now Yi Chen doesn't want to divulge his secret.

In the next few days, Yi Chen received supplies from the National Guard as promised. After discussing with everyone, he used some of the materials to rent a relatively clean duplex house in the yellow area for living.

They are not part of any alliance now, and it is safest to stay in the neutral zone. Of course, the prices here are higher than those in other alliance territories, so it's not okay to just sit on a mountain and eat nothing.

During this period, Yi Chen had a phone call with Ling Lan, who stayed in Zishan County Hospital.

Cheng Xianglong recovered relatively smoothly and was conscious. According to this trend, they will be discharged from the hospital in about a week, when they will rush to Xijing to join the team.

Considering the agreement reached with Zhou Shiwen, Yi Chen talked to the other party on the phone again, and frankly admitted that the materials transported from Nanchuan at that time were now his, and he hid them in the tunnel.

Yi Chen was not worried that Zhou Shiwen would make any moves if he knew about this, after all, he was still counting on himself to go to Nanchuan to find more other materials, and the materials in the three carriages were just a little drizzle for Zhou Shiwen.

The trickier one is the Wind and Cloud Alliance, which is sandwiched in the middle. They are the ones who blew up the bridge, they are the ones who are going to repair the bridge, and they are the ones who are going to repair the railway.

What Zhou Shiwen agrees to, he has to ensure that the Fengyun Alliance will not take action against it. Otherwise, if they sent someone to the other side of the tunnel again, there was no need for Yi Chen to say more, and the zombies stationed and wandering around the neighborhood would happily eat them as meals. If so, the railroad will be repaired.

Zhou Shiwen was surprised when he heard about this. He thought that the materials soaked in the soup were actually used by Yi Chen!

Although he is unwilling, but now he really can't help it, who let him use others?

"I will communicate well with the Fengyun Alliance, and they can't be hot-headed to break through the siege of thousands of zombies and snatch that little material." Zhou Shiwen said.

It's just that the more he asks for the Fengyun Alliance, the higher the chips the other party will offer.
