In one morning, Chen Xiao spent a lot of patience teaching him how to survive in this house - although this is an exaggeration, the process was not easy.

At the very least, Chen Xiao has successfully taught him how to use some household appliances - when they are plugged in! Because he seems to have no idea about electrical appliances such as televisions and microwave ovens, and the wire plugs on the back. She doesn't know how to plug it in to use electricity, but she has to reach out and touch it if she is used to it - she seems to like to discharge it herself.

Chen Xiao hurriedly stopped her, and asked her to be stern that in the future, she could not easily discharge electricity in non-essential situations.

He nodded simply, "Oh".

"Yi? Don't you even ask why? ”

Cha Cha smiled, her smile was a little apologetic, and the thin voice said softly: "I know, I asked a lot of questions last night, and you are a little distressed." So...... I don't ask. ”

"Actually......" Chen Xiaogang wanted to explain something, but after thinking about it, it was better not to ask, and he couldn't explain too much.

He successfully taught him how to use all kinds of household supplies, toothbrushes, water pipes, food in the refrigerator, what to eat and what to drink.

Fortunately, to Chen Xiao's surprise, this girl is actually extremely smart! One thing, she only needs to look at it once. Tell her anything, she only listens to it once, and she can remember it immediately!

Is it really unforgettable?

Chen Xiao patted her head and ran into the study—this was the old house left by her parents. Chen Xiao's parents were both high-level intellectuals back then, so naturally there were many books at home. He took out a copy of "Encyclopedia of Life" and threw it to him.

"After you read this, it should be useful to you."

The result surprised Chen Xiao again!

The more than 300-page "Encyclopedia of Life" took me less than an hour to read it. And when Chen Xiao asked her a few questions suspiciously, she memorized them all backwards!

"You ......" Chen Xiao looked at the innocent eyes of Ya Yan and muttered to himself: "I now have more and more doubts that you are not human." ”

At noon, Chen Xiao made a lunch. Although it is very simple for him to live alone, after all, there is a female guest in the house, and he is embarrassed to let people eat instant noodles all the time, but he personally went to the kitchen to make a fried rice and cut two tomatoes to make a soup.

But after all, he was by his side, staring at him with a "studious" look, although he was used to being stared at by those little girls while working in a fast food restaurant. But the beauty of her is much higher than that of those little girls, and the lethality index of her eyes has also increased exponentially......

Outcome......

"Ahh

Chen Xiao cut his finger.

She watched Chen Xiao scream, and there was a thin knife on her finger, but fortunately the injury was not deep, but the blood kept flowing. Chen Xiao sighed and turned around to get a band-aid, but saw her looking at her fingers, her eyes were a little unspeakably weird!

"What's wrong?" Chen Xiao frowned: "This is blood...... You haven't even seen blood, have you? ”

She shook her head, but glanced at Chen Xiao cautiously: "Can I ask questions?" ”

"Yes."

"Excuse me......" Yan Yan seemed to be a little worried: "Why is your blood red?" Have you also been infected with the virus? Are you going to die soon, too? ”

“……”

・

Taking a deep breath and trying to stay calm, Chen Xiao looked into her eyes and said in a calm voice: "First, human blood is originally red sè ......"

Seeing that she seemed to be about to say something, Chen Xiao waved her hand: "You let me finish first." ”

He looked into the girl's eyes: "Second ...... Since you said so, what do you think blood should be? ”

"Blue sè." He replied quickly.

As if to prove herself, she quickly picked up the kitchen knife on the cupboard, and before Chen Xiao could react, she had gently pierced her fingertips!

Chen Xiao's pupils contracted suddenly! Because it doesn't matter if he believes it or not. But the facts are right in front of you: the blood flowing out of the wound on her fingertips is the faint blue sè!

Ice blue sè like her eyes!

Blue Bloods?!

He vaguely remembered that he had read a popular science magazine, as if there were some strange descriptions of Lan Sè's blood, but it was too long ago to forget.

Chen Xiao was stunned for a moment, hiding the excitement in his heart, tore open a band-aid and wrapped his fingers, but quickly ran back to the study, turned on the computer, logged in to the Internet, opened google, typed "blue blood", search!

The search results are a bit troublesome: most of the search results are the novel "Blue Bloods" by the famous writer Mr. Ni Kuang. However, Chen Xiao still found some useful information.

Quickly browsing one by one, closing some useless web pages, Chen Xiao focused on a searched article:

“…… Some rare organisms lack a special enzyme in the body, resulting in blue sè blood, such organisms, such as a mollusk that has been found to live in the deep ocean for 3,000 meters, the blood lymph dissolves a blue sè protein called hemocyanin, which is also the main oxygen-carrying component, so it presents blue sè blood.

For a century, there has been a controversy about the existence of blue blood in humans, and it is speculated, for example, that blood blue blood cells have a much lower oxygen content than red blood cells in the analysis of blood samples taken from blue blood organisms. If there is really a blue sè blood human, then the oxygen-carrying content in the blood is too low, and it cannot ensure the normal needs of the human body. Therefore, the academic community has always held a negative view of the existence of blue-blooded people.

But another speculation is that if the blood blue blood cells are really hypoxic cells, then a corollary can also be drawn: we already know that one of the main reasons why the human body ages, is that the "oxygen" contained in the cells will cause the human body to age, which is called 'oxidation', and metals will deteriorate in the oxidation process, and the human body will do the same.

If there really are blue blood humans, then because the oxygen content of the blood in the body of such humans is lower than the normal level, then the metabolism of this kind of blood race is much slower than that of normal people, so the physical appearance develops slowly, and the aging is also extremely slow.

There is no conclusive conclusion as to whether the blue-blooded people really existed, but the author has consulted the information and in the early part of the last century, some scholars claimed that the existence of the blue-blooded people was found in a certain alpine area. Unfortunately, due to its age, it is impossible to find verifiable retained materials......"

The article was signed by a professor of biology in Germany.

Chen Xiao's studies are very good, at least his biology class is quite good. Therefore, he also knows a common sense: when people breathe, they inhale oxygen, so that the blood and red blood cells can get enough oxygen to maintain the normal operation of the human body.

In the same way, oxidation is a kind of overlook: the same is true for metals, such as silver, such as iron. Metals that are exposed to the air for a long time will rust, which is actually a process of oxidation.

If there is really blue sè blood, on the one hand, it can make the human body function normally...... In addition, it can be antioxidant and anti-aging......

That is, people with blue sè blood will ...... Eternal life?

Well...... "immortality" may be an exaggeration, but it is possible to age more slowly than normal people.

Seeing this, his heart jumped a little: Ya Ling, a blue-blooded man, really exists! Just in your own home, standing by your own side!

Seeing Chen Xiao running back to the room in a hurry, she sat at the computer and stared at the screen in a daze. She also followed quietly and stood beside Chen Xiao.

seemed to hesitate for a moment, and he was a little curious: "What's wrong?" Are you really infected with the virus? ”

Virus?

Wait, wait!!

Chen Xiao's heart moved!

Aside from the common sense that he doesn't know that "human blood should be red". The sentence she just said seemed to be weird too!

His exact words were: Are you "also" infected with the virus? Are you going to die "too"?

A seemingly simple sentence, with the addition of the word "also", seems to have a deeper meaning!

Staring at this girl, Chen Xiao's expression was very serious: "What did you mean by 'also' just now?" Do you know that there are other people besides you, whose blood is also blue? Why do you think that red blood is due to a viral infection? ”

Hearing this question, a faint sadness appeared on her soft face, and when she looked at it from the side, the contours of her face were shrouded in sadness, and her long eyelashes trembled slightly.

"Before...... Sixth, Eleventh, and Fourteenth were originally all the same as me, blue sè blood, but then the blood turned red sè......" His voice was sad: "They told me that No. 6, No. 11, and No. 14 would die because of the virus. ”

Chen Xiao keenly noticed that when he mentioned "them" again, his body still trembled involuntarily, and there was a deep fear in his tone that could not be concealed.
