"What's the solution?" asked Long Mei'er urgently. Pen ~ fun ~ pavilion www.biquge.info

"Perhaps, I can try to find a way to distinguish between humans and demons, as long as I find a way, I can at least take back some of the initiative!" Qin Yu said.

"How is it possible?" Long Mei'er almost couldn't believe her ears, Qin Yu actually said that she wanted to find a way to distinguish between humans and demons, this is a problem that the Thirteen Kingdoms Food Palace can't solve, how can you do it by yourself? It's impossible, it's completely impossible.

However, Qin Yu said: "Is it possible to reform weights and measures? How many great eats have not been done in the Thirteen Kingdoms, and even the saints have not done it, is it different for me to do it?"

"But this is not the same at all, the rules of the bloodline are absolute!" said Long Mei'er.

"Nothing is absolute!" Qin Yu took out the jade box and sealed the cloth stained with demon blood, holding the jade box tightly and said solemnly: "Start with demon blood!"

"Demon blood, what do you want to get?" Long Mei'er still didn't understand what Qin Yu meant.

"Let me ask you, why is human blood red?" Qin Yu asked, preparing to give Long Mei a vivid lesson in tissue biology.

"Why is it red? Isn't it red?" Long Mei'er's face was incredible, the blood was red, this was a simple fact, where was the reason?

Qin Yu shook his head, found a piece of paper, drew two lines on it with a pen, and drew many round cakes and some circles of other shapes between the two horizontal lines.

"Now let me tell you why the blood is red, look at these two lines, imagine it as the upper and lower boundaries of the longitudinal section of the blood vessel, can you imagine it?" Qin Yu pointed to the two horizontal lines on the paper.

Long Mei'er nodded, as a big eater, she often sees blood vessels in the process of meat processing, especially when dealing with the liver and heart, she can see the large arteries, and she is very clear about the lumen structure of the blood vessels.

"Blood flows between these two lines, and on the surface it looks like a puddle of red liquid, but in fact, blood is composed of a lot of very small blood cells and plasma, the so-called plasma, in fact, is a light yellow translucent tissue fluid, mainly composed of water, but also contains various proteins and other messy components. It's not important, it's the blood cells that are important, a large number of blood cells that are indistinguishable to the naked eye gather together, densely surging in the blood plasma, like a school of fish in a river, from which blood is formed. Qin Yu pointed to the various circles between the two lines and said.

"Wait, what are the cells?" Long Mei'er was stunned, she had always been knowledgeable, and for the first time, she had the feeling of listening to heavenly books.

"You just understand it as a very small and very small life, we are composed of various cells from head to toe, from the inside to the outside, to put it bluntly, we are the aggregate of a huge number of small lives, do you understand?" Qin Yu made a gesture.

Long Mei'er sighed with a disgusted expression: "It's disgusting, I'm obviously me, I'm not an aggregate!"

Fainting, what's so disgusting about this? Is this clearly the truth? Sure enough, there are still good things in the modern world, at least we understand what the hell we are.

No longer entangled with Long Mei'er about the problem of the aggregate, Qin Yu continued: "Blood cells mainly include red blood cells, white blood cells and platelets, white blood cells are equivalent to soldiers, mainly responsible for fighting, killing enemies who enter the blood, platelets are responsible for blood clotting and stammering, equivalent to repairmen, helping you block blood vessels and wounds in minutes." The number of red blood cells is the largest, they contain iron ions, they are red, they are equivalent to transporting an army, helping all your organs to deliver oxygen, without them you will quickly suffocate to death, so the blood is red, understand?"

Long Mei'er shook her head decisively, what Qin Yu said was completely beyond the scope of her cognition, and letting her accept so much information at once was equivalent to subverting her worldview, and it was impossible to accept it at all.

"It doesn't matter if you don't understand, you can imagine it. Qin Yu continued, "Human blood is red, because there are red blood cells, demon blood is black, and in the same way, demon blood must contain a special kind of demon cell, which is black, which causes demon blood to turn black." If humans and demons have human blood and demon blood, they must have red blood cells and black blood cells, or a kind of black and red blood cells in between, and if you can find this kind of cell and extract it separately, you can find its characteristics and weaknesses through experiments, and then find a way to test it on a large scale!"

"Are you serious?" Long Mei'er looked at Qin Yu blankly, and suddenly realized that Qin Yu was even more mysterious than she knew.

"Of course it's serious, humans and demons can hide the demon blood and make the blood look red, but the cells are too small to be completely controlled, it must contain free demon black cells, and once the demon qi erupts, a large number of black cells will be released, this cloth is proof!" Qin Yu pointed to the jade box in his hand, and his nervousness was finally relieved.

"What do you mean, what black cells are you going to extract from the demonic blood on this cloth?" said Long Mei'er began to gradually turn around.

"Yes, the demon race is born with a strong physique, and the cells must survive better than human cells, and there is a good chance that the extraction will be successful, as long as the extraction is successful, I will know what to do next. After Qin Yu finished speaking, he walked to the side of the bed and touched Shi Ji's forehead.

Even if Shi Ji fainted, her brows were still frowning, and she seemed to be in pain, feeling the temperature of Qin Yu's palm on her forehead, she gradually relaxed, and her breathing gradually became even and smooth.

"The physique of the demon clan is different from ours, the stone demon is a special case, the life span is unlimited, and the recovery period is equally long, her old injuries have not healed, and she has suffered such a serious injury, I am afraid that she will not wake up in a short time, so you can take good care of her." Long Mei'er also walked over, looking at Shi Ji's soothing expression, feeling strange in her heart, saying that sour is not sour, and she doesn't know what it feels like.

"You're not jealous?" Qin Yu saw the subtle change in Long Mei'er's expression.

Long Mei'er leaned into the chair next to the bed, glared at Qin Yu and propped up her chin and said, "Do you really think you're very fragrant when you eat a ghost's vinegar?" I tolerate her because I still have a five-year contract with her. ”

Yes, she started to be arrogant again, Qin Yu didn't break it, let go of the hand covering Shi Ji's forehead, and instead took Long Mei'er's hand and put it on it, "Since you are so looking forward to her getting better, you will take care of her." ”

"I?take care of her?, what about you?" Long Mei'er pointed at herself in disbelief and then at Shi Ji.

"It's easier for you to take care of her, I have to hurry up and study the demon blood, do you want me to scrub and change her clothes? Qin Yu spread out his hand.

"You want to be beautiful, go while studying!" Long Mei'er immediately pushed Qin Yu away, and took the initiative to take care of Shi Ji's task, although she knew that Qin Yu couldn't do anything to Shi Ji, she still couldn't accept Shi Ji's honesty in front of Qin Yu.
