The young lady at the front desk picked up the phone, pressed a number, and dialed it after a while.

"Hey, is it Dr. Sun Yu?"

"It's me, what's the matter?"

"There's a guy on the first floor looking for you."

"I'm busy now, you can tell him to wait a while, or just send him away."

"But..."

Chen Xiao saw that there was no news for a long time, so he realized that something was wrong, and secretly used his prediction ability.

"I didn't expect this Sun Yu's shelf to be so big, it's really an official who crushes people to death." Chen Xiao thought to himself.

Chen Xiao hurriedly stepped forward, snatched the mobile phone from the front desk, and said inside.

"Hey, is it Sun Yu? I'm Chen Xiao, come down for me! ”

There was an instant silence on the other side, and then there was a sound of slamming the door.

After a while, Sun Yu ran down from upstairs in a hurry, and when he saw Chen Xiao, he hurriedly hugged him.

"Chen Ke, I thought I'd never see you again!" Sun Yu said with tears in his eyes.

Chen Xiao smiled slightly and said to Sun Yu with a slight mockery.

"It seems that you are doing well here, the pie is so big, someone looking for you doesn't want to come down to pick it up!"

Chen Xiao's sharp eyes stared at Sun Yu tightly, and Sun Yu could only smile awkwardly.

"Teacher, you don't know, I've been so busy these two days, I've been studying the problem of mutants, and my head is big." Sun Yu pinched her temples and said slowly.

Chen Xiao's eyes suddenly lit up when he heard the study of the mutant, and he hurriedly asked.

"Oh? Did you come up with anything? ”

"It's not clear here, let's go to the lab."

After Sun Yu finished speaking, just when she wanted to go back, she found that Chen Xiao was carrying a cute little girl next to her, and she asked hurriedly.

"Teacher, who is this little girl?"

Chen Xiao glanced at Chen Xi and said hurriedly.

"Oh, I forgot to introduce you, this is my daughter Chen Xi, Xiaoxi, this is my father's student, Sun Yu."

"Hello Aunt Sun Yu!" Chen Xi said with a smile.

"I didn't expect your daughter to be so cute, so happy!" Sun Yu touched Chen Xi's head and said with a smile.

"Don't be envious, it's useless to be envious."

After joking, the three of them walked upstairs together, the laboratory was on the third floor, and the second floor was the conference room, where someone seemed to be in a meeting.

Chen Xiao pulled Chen Xi and followed Sun Yu slowly to the third floor and entered a room.

It's a very formal lab with everything you need.

Sun Yu came to a table, and Chen Xiao sat next to her. Chen Xi was put on the sofa by Chen Xiao and watched TV.

I saw Sun Yu open the computer in front of him, took a form and a row of test tubes by the way, and handed them to Chen Xiao. After Chen Xiao took it, he looked at it carefully.

"This is..."

Chen Xiao looked at the form in his hand, his eyes kept flickering, and his brain kept turning.

This is a table of the proportions of sand and moisture in the mutant, as well as a composition table of the moisture element.

"The sand in the mutant body accounts for 60%, the 'moisture' element accounts for 10%, and the water content accounts for 0%..."

"That's right, while sand is only found outside the cell wall, but moisture is found deep in cells, in blood vessels, bones, and even in the brain." Sun Yu turned his head and said.

"What about moisture? Disappeared into thin air? Chen Xiao asked suspiciously.

"Look at this."

Chen Xiao put down the form and looked at the computer that Sun Yu pointed to.

A video is playing on the computer, which appears to be an anatomical process.

A dead mutant was strapped to a bed, and since it had no organs, the dissection process became very fast, and the corpse was divided into three parts: muscle, bone, and brain.

The muscle is still intact, but the doctor's cutting has found that it is very regenerative and it only takes a few seconds for the wound to heal completely, but at the same time, the skin will dry out a little until the skin is completely dry, and finally it will become a mess of sand.

Sun Yu clicked the mouse, and the screen turned to a picture.

"Look at this picture, this is a horizontal screenshot of the mutant's muscles, its blood vessels are full of moisture, but the water disappears, which shows that the moisture element dilutes the water, and after our experiments, we found that this is indeed the case."

Sun Yu picked out two test tubes in a row of test tubes on the table and showed them to Chen Xiao to watch.

"This tube is a blood-like solution taken from a mutated body, this tube is an ordinary aqueous solution, and now fuse them together."

Two bottles of solution were poured into a flask, and something magical happened, at first the blood-like solution and the aqueous solution were in a layered state, the blood-like solution was on top and the aqueous solution was on the bottom. But after a while, the upper solution begins to penetrate the lower solution.

At the same time, the most strange thing is that in the process of continuous downward penetration of the upper solution, the upper solution begins to gradually become granularized, and finally turns into yellow crystals.

In the final state, the aqueous solution at the bottom is completely diluted and becomes the same solution as the previous blood-like solution, while the upper layer becomes a yellow crystal.

"Is the crystalline above this... Sand? Chen Xiao asked softly.

"That's right." Sun Yu nodded.

"It can be found that moisture not only fluidizes the sand, but also dilutes the water and turns it into crystals like sand."

"That's why the mutant is filled with sand." Chen Xiao nodded silently.

Sun Yu's fingers operated again, and the picture switched instantly, which were the cross-sections of the bones and the brain, and the situation was the same as the previous picture, and the water in it also disappeared.

Chen Xiao turned his gaze to another table, which recorded the composition and specific information of the 'moisture' element.

"Moisture, a rare element, consists of a highly corrosive liquid of unknown composition. It reacts with water to become sand, and with sand it reacts to become water. In addition to being highly corrosive, it is also highly reproducible, so as long as it does not damage the central system, it will not kill immediately. ”

After Chen Xiao finished reading the form, he asked Sun Yu.

"So, we still haven't been able to find out the specific composition of moisture? If we can do that, we might be able to find a way to fight the mutants. Maybe they can be brought back to life. ”

Sun Yu shook his head and said slowly.

"Basically, there is no hope, not to mention the question of whether the ingredients can be studied, even if it is studied, it will not be possible to develop a vaccine immediately, and even if a vaccine is studied, all the body organs of the mutant have been corroded, and it is impossible to save it again."

"There is always hope, and we cannot sit idly by." Chen Xiao said firmly.

Just as the two of them were in full swing of discussion, the door of the laboratory was slowly pushed open, and another man came in from outside, this person was tall and magnificent, and from the perspective of temperament, he was a particularly proud and arrogant person.

And he was still holding a handful of roses in his hand, as if he had come to Sun Yu on purpose, as soon as Sun Yu saw this man, he had a disgusted, but helpless expression.

The man saw that Sun Yu was chatting with a strange man and chatting enthusiastically, and he couldn't help but have a trace of anger in his heart, but in front of Sun Yu, he couldn't lose his temper, so he had to hold back his anger and say softly.

"Xiaoyu, this is the rose I bought for 500 competition points, you must accept it, otherwise, it will be too wasteful of my heart!"

Sun Yugang wanted to refuse, but Chen Xiao preemptively said.

"This flower is very beautiful, we have received it, you can go back first!"

Chen Xiao took the flowers from the man's hand, and the man looked at Chen Xiao with disdain, Sun Yu had no choice but to smile awkwardly and say to the man.

"Well, you go back first, I'll take this flower."

"Okay, you can take it, then I'll go back first!

The man turned to leave, and Sun Yu hurriedly asked Chen Xiao.

"Teacher, why do you want to accept this flower, I don't like him either."

"Didn't you hear? He said that it cost 500 competition points, how can it be wasted! What's more, he is a capable person, and he is very capable, and you rebel against him, will you still have a place in this camp? ”

Sun Yu sighed and said slowly.

"It seems that the teacher is still discerning, he is indeed a master, Qu Ying who is ranked 100th on the list."

Chen Xiao nodded, didn't say more, feelings are the most taboo to be interfered with by others, and it's not right to match, it's not right to push away, it's better to let her solve it by herself.
