In one morning, Chen Xiao spent a lot of patience teaching Yaya how to survive in this house - although it is a bit exaggerated to say this, the process was not easy.
At least, Chen Xiao successfully taught Yaya how to use some household appliances—while plugging them in! Because Yaya seems to have no idea about the electrical plugs at the back of electrical appliances such as TVs and microwave ovens. She doesn't know how to connect the plug to use it, but habitually reaches out to touch it - she seems to like to discharge electricity by herself.
Chen Xiao quickly stopped her and asked her sternly that in the future she should not discharge her electricity easily unless necessary.
Yayao simply nodded and said "oh".
"Yi? Don't you even ask why?"
Cha Cha smiled, with some apology in her smile, and said softly in her thin voice: "I know, I asked a lot of questions last night, and you were a little distressed. So... I won't ask any more."
"Actually..." Chen Xiaogang wanted to explain something, but then he thought, even if he didn't ask, he couldn't explain much.
Successfully taught Yaya how to use various supplies at home, including toothbrushes, how to drain water from water pipes, and the food in the refrigerator, which ones are for eating and which ones are for drinking.
Fortunately, to Chen Xiao's surprise, this girl was actually extremely smart! She only needs to read a thing once and know it immediately. Whatever you tell her, she only listens to it once and remembers it immediately!
Is it really a photographic memory
Chen Xiao slapped his head and ran into the study - this was the old house left by his parents. Chen Xiao's parents were both high-level intellectuals back then, so there were naturally many books at home. He pulled out a "Little Encyclopedia of Life" and threw it to Yaya.
"After reading this, it should be useful to you."
The result surprised Chen Xiao again!
It took Yaya less than an hour to read the more than 300-page "Life Encyclopedia". And when Chen Xiao asked her a few questions, she knew them all by heart!
"You..." Chen Xiao looked at Yaya's innocent eyes and murmured to himself: "Now I am increasingly doubting that you are not human."
At noon, Chen Xiao made lunch. Although it was very simple for him to live alone, after all, there was a female guest at home, and he was embarrassed to always let her eat instant noodles. Instead, he went to the kitchen and made a portion of fried rice, and cut two tomatoes to prepare. A serving of soup.
But after all, Yaya was right next to him, staring at him with a "study" look on his face, even though he was used to being stared at by those little girls while working in a fast food restaurant. But Yaya is far more beautiful than those little girls, and the lethality index of her eyes has also increased exponentially...
result…
"ah!"
Chen Xiao cut his finger.
Yayao watched Chen Xiao scream, and there was a thin cut on his finger. Fortunately, the injury was not deep, but the blood kept flowing. Chen Xiao sighed and turned around to get the band-aid, but he saw Yaya looking at his fingers with an indescribably weird look in his eyes!
"What's wrong?" Chen Xiao frowned: "This is blood... You haven't even seen blood, have you?"
Yayao shook his head, but looked at Chen Xiao cautiously: "Can I ask a question?"
"Can."
"Excuse me..." Yaya seemed worried: "Why is your blood red? Are you also infected with the virus? Will you die soon?"
“…”
…
Taking a deep breath and trying to stay calm, Chen Xiao looked into Yaya's eyes and said in a calm voice: "First, human blood is inherently red..."
Seeing that Yaya seemed to be about to say something, Chen Xiao waved his hand and said, "Let me finish first."
He looked into the girl's eyes: "Second... Now that you said that, what color do you think blood should be?"
"Blue." Yayao answered quickly.
As if to prove herself, she quickly picked up the kitchen knife on the counter, and before Chen Xiao could react, she had gently pricked her fingertip!
Chen Xiao's pupils suddenly shrank! Because it doesn’t matter whether he believes it or not. But the fact is right in front of you: the blood flowing out of the wound on Yaya's fingertip is faint blue!
Just like her eyes are ice blue!
Blue blooded people? !
He vaguely remembered that he had read a popular science magazine, which seemed to have some strange descriptions about blue blood, but it had been so long ago that he had forgotten it.
Chen Xiao was stunned for a moment, concealing the excitement in his heart, tearing off a band-aid and wrapping it on Yaya's finger, but quickly ran back to the study, turned on the computer, logged into the Internet, opened GOOGLE, typed "blue blood", and searched !
The search results are a bit troublesome: most of the search results are the "Blue Blood Man" novel by the famous writer Mr. Ni Kuang. However, Chen Xiao still found some useful information.
After quickly browsing one by one and closing some useless web pages, Chen Xiao focused on an article he found:
"... Certain rare organisms lack a special enzyme in their bodies, causing their blood to turn blue. Such organisms, such as a mollusk that has been discovered to live three thousand meters under the deep ocean, dissolve in the hemolymph called The blue protein of hemocyanin is also the main oxygen-carrying component, so blood appears blue.
For a century, the question of whether there is a race with blue blood among humans has been a controversial topic. According to speculation, for example, analysis of blood samples extracted from known blue-blood organisms shows that the oxygen content of blue blood cells is much lower than that of red blood cells. . If there really are humans with blue blood, then the oxygen-carrying component in the blood is too low to meet the normal needs of the human body. Therefore, the academic community has always held a negative view on the existence of blue-blooded people.
But another guess is that if the blood blue blood cells are really hypoxic cells, then we can also draw an inference: At present, we already know that one of the main reasons why the human body ages is that the cells contain "Oxygen" will cause the human body to age, which is called 'oxidation'. Metals will deteriorate during the oxidation process, and the same goes for the human body.
If there really are humans with blue blood, then because the oxygen content of their blood is lower than normal, the metabolism of humans with this type of blood will be much slower than that of normal humans, so their physical appearance will develop slowly and age. Also extremely slow.
There is currently no conclusion as to whether blue-blooded people really exist, but the author has consulted information and found that at the beginning of the last century, some scholars claimed that blue-blooded people were found in a certain high mountain area. It’s a pity that due to its long history, no verifiable preserved information can be found at present…”
This article is signed by a German biology professor.
Chen Xiao's academic performance is pretty good, at least his biology class is pretty good. So he also knows a common sense: when a person breathes, he inhales oxygen, so that the blood red blood cells get enough oxygen to maintain the normal operation of the human body.
In the same way, oxidation is also a kind of overlooking: the same is true for metals, such as silver and iron. Metal exposed to air for a long time will rust, which is actually an oxidation process.
If there really is blue blood, on the one hand, it can make the human body function normally... and on the other hand, it can resist oxidation and aging...
In other words, people with blue blood will be... immortal
Uh... The statement "immortality" may be an exaggeration, but it is possible to age slower than normal people.
Seeing this, his heart jumped a little: Yaya, the blue-blooded man, actually exists! Right in your own home, standing next to you alive!
Yayao saw Chen Xiao running back to the room anxiously, sitting by the computer and staring at the screen in a daze. She also followed quietly and stood next to Chen Xiao.
Seemingly hesitating, Yaya was a little curious: "What's wrong? Are you really infected with the virus?"
Virus
Wait, wait a minute! !
Chen Xiao's heart moved!
Aside from the fact that Yaya doesn’t know the common sense that “human blood should be red”. What she just said seemed weird!
Yaya's original words were: Are you "also" infected with the virus? Will you die "too"
A seemingly simple sentence seems to have a deeper meaning with the addition of the word "ye"!
Staring at the girl, Chen Xiao's expression was serious: "What do you mean by 'also'? Besides you, do you know of anyone else whose blood is blue? Why do you think that red blood is Is it because of a viral infection?”
Hearing this question, a hint of sadness appeared on Yaya's soft face. Looking from the side, the outline of her face was shrouded in sadness, and her long eyelashes trembled slightly.
"Before... No. 6, No. 11, and No. 14 were originally the same as me, with blue blood, but then the blood turned red..." Yaya's voice was filled with sadness: "They told me that No. 6, No. 10 Numbers 1 and 14 will die due to viral infection."
Chen Xiao keenly noticed that when Yaya mentioned "them" again, her body still trembled involuntarily, and there was a deep fear that could not be concealed in her tone.
