Under the moonlight at night, the familiar figure of the man walked under the dueling arena, full of momentum.

"The sheriff's deterrent power is still strong?!" Chen Xiao said softly.

The two hid behind the stands, and waited until the sheriff walked past before they slowly poked their heads out.

Chen Xiao exhaled, looked at Sun Yu, who was still unsettled, and asked in a low voice.

"Are you alright? You weren't hurt, were you? ”

"It's okay... By the way, you said you were looking for me? Can I help you? Sun Yu said softly.

Chen Xiao patted his head fiercely, and finally remembered the reason why he came to Sun Yu today.

"I'd like to discuss a few issues with you."

"Oh? You say. ”

Chen Xiao stabilized his mind, he had a lot of questions, but there were no answers, and he wanted to find someone to discuss them.

"Where are you researching now? It is said that Mi Guo has studied the cause of the mutation, and has also explained the reason for the emergence of two forms, mutants and abilities. ”

Sun Yu straightened his messy hair and said slowly.

"I also saw that report, and their analysis was basically correct, but it was not comprehensive enough."

"Oh? How so? ”

"According to researchers in the United States, moisture can react with sand to become moisture, and it can react with water to become sand, but this is not very accurate."

Sun Yu grabbed a handful of sand casually, mentioned it in front of Chen Xiao, and said slowly.

"You see, this is ordinary sand, it hasn't been reacted with moisture, it's in this granular form, and the surface is very rough."

"However, after the reaction of moisture and water, the sand formed is crystalline, and the surface is very smooth, which is completely different from ordinary sand."

Chen Xiao took the sand from Sun Yu's hand and observed it carefully.

He really didn't realize before, what is the difference between the two, the appearance is the same, after killing the zombie, he didn't study it carefully, it turns out that the two are different.

"Therefore, the sand in those zombies should essentially be called sand crystals, referred to as sand crystals, which is not the same as the sand as mentioned by the United States."

Chen Xiao nodded and continued to ask.

"What about the moisture? Any questions? ”

"Well, there's nothing wrong with that, but it's not just the moisture that reacts with the sand, but the carbon dioxide." Sun Yu said softly.

"Carbon dioxide?"

"Yes, when the moisture element first reacted with the sand, it was actually another gas generated, this gas we have not yet studied, this gas is not corrosive, but it can have a chance to strengthen creatures, which is the cause of the current ability."

Chen Xiao's eyes flashed, and a flash of inspiration appeared in his head.

"Then if this gas can be mass-produced, wouldn't it be possible to raise the evolution of human beings to a higher level?!"

"Yes, but we don't have moisture right now, so we can't do that kind of mass production results." Sun Yu said softly.

Chen Xiao was very excited, as a biologist, his life's academic research was to make human beings become a better and more perfect creature, and the person behind the scenes must have the same idea.

But Chen Xiao didn't agree with his idea, if just for academic research, the entire human race on the earth was used as an experiment, the price would be too great, this was a devastating experiment, but if it was himself, he would definitely not joke with so many people's lives.

Sun Yu paused for a moment and continued.

"This gas reacts with the carbon dioxide exhaled by people to form moisture gas, and then it is inhaled into the body by people, and then reacts with the water molecules in the body again, so that people mutate into zombies."

"This also explains why people are divided into mutants and abilities, sandstorms, some people are buried in the sand, and some people find a place to hide in advance, but they don't know that hiding outside is actually the most dangerous, and it is safe to be submerged in the sand."

Sun Yu grabbed another handful of sand from the side and put it in front of his eyes to watch.

"This may also be the choice of God, some people are destined to become victims of fate, and some people will become saviors."

Sun Yu turned his head to look at Chen Xiao and said with a smile.

"Teacher, will you be a savior?"

Faced with this sudden question, Chen Xiao was speechless.

He never thought about this problem, as a member of more than 1000 million people on the earth, he never had any ambitions, his only dream was to break out of the world in his own research field, and he had no such idea of saving the world.

But since he found that there was someone behind this disaster, and that his thoughts were the same as his own, then he had to take care of it and prove that his ideas were wrong!

Chen Xiao did not answer Sun Yu's question, but looked into the distance.

"The savior is too far away, and for now, I just want to protect myself, my companions, and of course, my daughter."

If you want to save others, you must first ensure the safety of yourself and your companions, if you can't even protect your own safety, then how can you speak out and save the world?

Sun Yu looked at Chen Xiao's side face and smiled slightly.

"I believe you can, my little girl can only study silently behind her back, and you are different, you are the one who is capable, this is God's choice, you must be the dragon and phoenix among people."

Chen Xiao waved his hand and said in a low voice.

"Okay, okay, don't talk about it, you haven't said you have found anything?"

"Me? When you say that, I really have a discovery, and it's a big discovery. Sun Yu said in a low voice.

"Oh?"

Sun Yu looked around, and after making sure that there was no one, he leaned over to Chen Xiao and said softly.

"I found a vaccine that protects against moisture."

"What?!"

Chen Xiao couldn't help but shout, and after realizing that he was too aggressive, he gradually calmed down.

"What do you say? Found a vaccine?! Chen Xiao asked excitedly again.

Sun Yu made a shushing gesture and said softly.

"Don't get excited, it's just that there are signs, and you haven't really studied it yet."

"Tell me about it!"

Chen Xiao was also very excited to hear that Sun Yu had developed a vaccine, which means that those who have become zombies are likely to be saved, and those who have been bitten do not have to be afraid of becoming zombies.

Thinking of this, Chen Xiao thought of Lao Qin and his wife again, if there is a vaccine, then they can also continue the frontier.

Sun Yu glanced at Chen Xiao, who was so excited, and couldn't help but regret a little in his heart, telling him so early, after all, he had just discovered a little spearhead.

"Recently, I have conducted targeted research on the sand crystal, using fire, freezing, or various potions to react, and I have found a substance that can make it disappear completely."

"What substance?"

"It's hydrogen peroxide, and sand crystals can react with hydrogen peroxide to produce water and oxygen."

When Chen Xiao heard this, his eyes couldn't help but light up, this discovery is very important, but even so, hydrogen peroxide and hydrogen peroxide are carcinogens and cannot be taken or injected. Generally, it is only used for wound disinfection, and it cannot be used to make vaccines.

"But hydrogen peroxide can't be taken, and even if it can be taken and the sand crystals in the corpses are all reacted, it can't let them survive." Chen Xiao asked softly.

"Yes, I haven't developed a hydrogen peroxide solution that can be taken yet, and even if I do, I can't save those mutated humans."

Chen Xiao nodded and did not speak.

This also means that those poor mutants can only wander outside in a state of confusion for the rest of their lives.

And Lao Qin's wife may always remain in that state.

Sun Yu saw that Chen Xiao didn't speak, and he also looked sad.

"Don't be discouraged, we still have a long way to go, what if we come up with a vaccine that can perfectly solve the problem of moisture? It's impossible to say. ”

"Maybe, then you bother more, if you don't understand something, just call me, I'll go over when I find time." Chen Xiao said softly.

Chen Xiao is also tired, qualifying, training the newly recruited younger brother, improving the living environment of Wu Meng's mother and daughter, and taking time to accompany her daughter, and now there is another vaccine thing, which is really too busy.

Chen Xiao could only agree to come down first, and then take the time to take a look and help.
