Chapter 5, Blue Blood

Upon seeing this, his heart began to race: the Yaya, the blue-blooded people, actually exist! Right in his own home, standing alive beside him!

Regarding the existence of blue-blooded individuals, there is currently no definitive conclusion. However, the author has previously researched materials indicating that in the early 20th century, some scholars claimed to have discovered a race of people with blue blood in certain mountainous regions. Unfortunately, due to the passage of time, it is now impossible to find verifiable records of this.

Quickly browsing through one page after another, closing some useless websites, Chen Xiao focused her attention on an article that had been found in the search results

The result once again surprised Chen Xiao

Chen Xiao was momentarily stunned, concealing the excitement within her heart. She tore off a strip of adhesive bandage to wrap around Ya Ya's finger, but quickly ran back to the study, opened the computer, logged onto the internet, opened GOOGLE, and typed "blue blood" to search!

Chen Xiao looked at Ya Ya's innocent eyes and murmured, "I am increasingly beginning to doubt that you are not human."

In fact, Chen Xiao was about to explain something, but then thought better of it; it was perhaps better not to ask, as he himself could not provide much of an explanation.

Upon hearing this question, a trace of subtle sadness appeared on Yaya's delicate face. From the side, her facial contours were shrouded in sorrow, and her long eyelashes trembled slightly

... ...

Uh... the phrase "immortality" may be somewhat exaggerated, but it is indeed possible to age more slowly than the average person

At noon, Chen Xiao prepared a lunch. Although he usually lived a simple life with only books, he felt it was inappropriate to keep serving instant noodles to his female guest. Therefore, he personally went to the kitchen to make a fried rice and also sliced two tomatoes in preparation for a soup.

However, another hypothesis is that, similarly speculating, if blood blue cells are indeed low-oxygen cells, then we can draw a conclusion: we already know that one of the main reasons for human aging is the presence of "oxygen" within cells, which leads to bodily aging, a process referred to as 'oxidation'. Just as metals deteriorate during oxidation, the human body does as well

Yaya looked at Chen Xiao's scream, noticing a thin cut on her finger. Fortunately, the wound was not deep, but blood continued to flow. Chen Xiao sighed and turned to get a band-aid, only to see Yaya staring at her finger with an indescribably strange expression.

Chen Xiao cut his own finger

Gazing at the girl, Chen Xiao's expression was very serious: "What do you mean by 'also' that you just mentioned? Besides yourself, do you know of anyone else whose blood is blue? Why do you think that red blood is due to a viral infection?"

Qia Qia smiled slightly, her smile carrying a hint of apology. In a soft voice, she gently said: "I know I asked a lot of questions last night, and you seemed a bit troubled. So... I won't ask anymore."

If there were truly blue blood, it could not only enable the normal functioning of the human body but also provide antioxidant properties and combat aging

Certain rare organisms lack a special enzyme in their bodies, resulting in blue blood. Such organisms include a type of mollusk discovered at a depth of 3,000 meters in the deep sea, which contains a blue protein called hemocyanin dissolved in its hemolymph. This blue protein is also the primary component for oxygen transport, hence the blue color of the blood

virus

Yaya watched as Chen Xiao hurriedly ran back into the room, sitting beside the computer and staring blankly at the screen. She quietly followed and stood next to Chen Xiao

Chen Xiao's academic performance is quite good; at least he excels in his biology class. Therefore, he is aware of a common fact: when a person breathes, inhaling oxygen allows the red blood cells in the blood to receive sufficient oxygen, which is essential for maintaining the normal functioning of the human body

Wait, wait a moment

The child shook her head but cautiously glanced at Chen Xiao and asked, "May I ask a question?"

Similarly, oxidation is also a form of overlooking: metals are no exception, such as silver and iron. Metals that are exposed to air for an extended period will rust, which is essentially a process of oxidation

Did you "also" get infected with the virus? Will you "also" die?

Chen Xiao slapped his forehead and ran into the study—this was the old house left by his parents. Both of Chen Xiao's parents were highly educated intellectuals, so naturally, there were many books in the house. He dug out a book titled "Encyclopedia of Everyday Life" and tossed it to Ya Ya

Just like her eyes, which are an icy blue color

Taking a deep breath and trying to remain calm, Chen Xiao looked into Ya Ya's eyes and said in a soothing voice: "First, human blood is originally red, just like in the illustrations..."

Blue Bloods

May I ask... it seems that the child is somewhat worried: "Why is your blood red? Have you also been infected with the virus? Are you going to die soon as well?"

As if to prove herself, she swiftly picked up the kitchen knife from the countertop, and before Chen Xiao could react, she had already gently pierced her fingertip

At the very least, Chen Xiao successfully taught Ya Ya how to use some household appliances—under the condition that they are plugged in! This is because Ya Ya seems to have no concept of the power cords and plugs of appliances like televisions and microwaves. She does not understand that the plugs need to be connected in order for the appliances to function, and instead, she instinctively reaches out to touch them—it seems she enjoys generating electricity herself

It is possible

After hesitating for a moment, Ya Ya felt a bit curious: "What’s wrong? Have you really contracted the virus?"

Having read this, it should be useful to you

In other words, will people with blue blood ... ? ... achieve immortality

Blue, the child replied quickly

The search results were somewhat troublesome: most of the results were from the famous writer Ni Kuang's novel "Blue Bloods." However, Chen Xiao still managed to find some useful information

In the past, No. 6, No. 11, and No. 14 were all the same as me, with blue blood, but later the blood turned red. The child's voice carried a sorrowful tone: "They told me that No. 6, No. 11, and No. 14 died because they were infected by the virus"

Success has taught the child how to use various household items, such as the toothbrush, water, and how to pour water from the library, as well as the food in the refrigerator, distinguishing between what is for eating and what is for drinking

After all, Ya Ya is right beside me, looking at me with a face full of eagerness to learn. Although I have become accustomed to being watched by those young girls while working in the fast-food restaurant, Ya Ya's beauty far surpasses that of those girls, and the intensity of her gaze increases exponentially.

For a century, the existence of a blue-blooded race among humans has been a contentious topic. According to speculation, for instance, the analysis of blood samples extracted from known blue-blooded organisms shows that the oxygen content in blue blood cells is significantly lower than that in red blood cells. If blue-blooded humans truly exist, the oxygen-carrying component in their blood would be insufficient to meet the normal requirements of the human body. Therefore, the academic community has consistently held a negative view regarding the existence of blue-blooded individuals.

The child simply nodded and said, "Oh."

Fortunately, what surprised Chen Xiao was that this girl was exceptionally intelligent! She could grasp a matter after just one glance. Whatever she was told, she only needed to hear it once to remember it immediately

If there were indeed humans with blue blood, then such individuals would have a lower oxygen content in their blood compared to normal levels. Consequently, the metabolism of these individuals would be significantly slower than that of normal humans, resulting in a slower physical development and an extremely slow aging process

Ah!

A seemingly simple sentence, when the word "also" is added, seems to carry a deeper meaning

He vaguely remembers having read a popular science magazine, which seemed to contain some strange descriptions about blue blood and illustrations, but it has been too long, and he has already forgotten.

... ... ''

Is it truly the case that one can remember everything at a glance

Chen Xiao keenly noticed that when Ya Ya mentioned "they" once again, her body involuntarily trembled slightly, and her tone could not conceal a deep-seated fear.

result

During one morning, Chen Xiao spent a great deal of patience teaching the child how to survive in this house—though this may sound somewhat exaggerated, the process was by no means easy

Chen Xiao's pupils suddenly constricted! Because whether he believed it or not, the fact was right before his eyes: at the wound on Ya Ya's fingertip, the blood flowing out was a faint blue!

Seeing that the child seemed to want to say something, Chen Xiao waved his hand and said, "Let me finish speaking first"

He looked into the girl's eyes: "Then... since you said that, what color do you think blood should be?"

Setting aside the fact that the child does not know the common knowledge that "human blood should be red," the statement she just made also seems peculiar

The more than 300-page "Encyclopedia of Life" was finished by the child in less than an hour. Moreover, when Chen Xiao skeptically quizzed her on a few points, she recited them flawlessly

Chen Xiao felt a stir in her heart

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

Why don't you ask why?

Chen Xiao quickly stopped her, sternly demanding that she should not discharge electricity casually in non-essential situations in the future
