It's almost early in the morning.

This day was disturbing and thrilling, and a lot of blood was donated, Wanwan finally couldn't stand it, so Zhao Mengqi forced her and Zhao Yun to rest first.

Zhao Wei was quite energetic, so she stayed to take care of Qian Duo.

Tucked the quilt for Qian Duo, Zhao Mengqi looked around the room, "Put out all the extra lights, and don't crowd too many people here, lest the air be too turbid, just leave Qingyu alone in the inner room to take care of, let's just go outside and guard it."

A group of people went to sit outside, and in addition to Zhao Mengqi and Zhao Hui, there were also Imperial Doctor Chong and several of his apprentices.

After a few sips of tea, the question in his stomach made Doctor Chong unable to hold it anymore.

"Your Highness, your blood transfusion method is indeed miraculous, and after being applied, it will be able to save countless lives, but Weichen is stupid and can't understand the mysteries, I wonder if Your Highness can teach it?"

"Well, this was originally going to be handed over to you to study, after all, it's just my layman's idea, not to mention any mystery, it's a fluke that everything can go well today, if you have any doubts, I can try to answer them, but it's not necessarily right, I just hope to bring you ideas, and then research and verify the real mystery."

Zhao Mengqi is self-aware, and knows very well that he is just relying on the information of later generations to develop, and knows some common sense and skin, and there is also the possibility of one-sidedness and memory errors, and this kind of professional knowledge still depends on professional people to experiment and explore.

"Your Highness is too humble, you have the talent to go through the heavens and the earth, even if you think about it, you can also have a shocking magic, of course, Your Highness shoulders the whole world, you only need to build from a high vantage point, and leave the trivial and specific affairs to our ministers......

Zhao Mengqi couldn't help but roll his eyes, "Okay, don't shoot the sycophants, let's get down to business."

Doctor Chong was embarrassed, feeling that his sycophant skills still needed to be improved, "Your Highness, Weichen has already understood that this blood transfusion should pay attention to adaptation, and the method of blood test is roughly the same as the method of blood dropping to recognize relatives, does that mean that the closest relatives are suitable and can transport blood to each other?"

"The fact that you can notice this means that you have some ideas." Zhao Mengqi showed a look of relief, and then said with a straight face, "But the method of dripping blood to recognize relatives is actually wrong, and the blood between relatives may not be suitable, speaking of this, I have to talk about the concept of "heredity" first."

"It's wrong to confess your relatives by dripping blood!? What does heredity mean? Legacy? But what does it mean?" Doctor Chong pondered seriously.

"It's almost the meaning of bloodline, whether it is a human being or any other living being, it will have similar or identical traits to their ancestors, and we can call it heredity."

This is not difficult to understand, because the ancients also observed and explored all things in heaven and earth, and also explained and expressed many phenomena, but the words used were different.

Zhao Mengqi organizes language and tries to use words that are easy to understand, "Just as the transmission of knowledge needs to be achieved through the medium of language and books, then heredity probably needs to be achieved through some kind of medium, which can be called "genetics"."

Imperial Physician Chong nodded, and then came to his senses, "Qin Duan, Chongzhi, Yuan Hua, hurry up and take pen and ink and write down His Highness's words, and not a word is missing!"

At this time, he already had a faint feeling that King Yan was about to teach an amazing content, and from then on opened the door to understand the ultimate meaning of life, which made his whole body tremble with excitement.

Zhao Mengqi shrugged his shoulders and waited until they had found their pen and ink and recorded everything they had said before continuing to speak.

"As far as that chicken is concerned, it was just an egg at first, and when it was cracked, it was filled with egg whites and yolks, which looked simple and pure, but under the action of genes, the egg gradually developed complex tissues such as bones, flesh and organs, and finally hatched into a chick."

"It's also the genes that make the eggs hatch only chicks and not other species, and of course, the premise is that the hen that laid the eggs has been mated to the rooster...... Also, don't ask me if I came first with the chicken or the egg!"

Hearing the word "matching", Zhao Hui's face turned red, and she couldn't help but pinch Zhao Mengqi, "Fourth brother, Bao Niang is a daughter's family, can you pay attention?"

, this trick is a woman's birth

, or teach each other, except for Zhao Yun, why do they all use it on me?

"Am I not paying enough attention to my words? If you're shy, then don't listen, anyway, you're a princess, it's useless to listen......

Zhao Hui was unconvinced, "Who said that it would be useless if I listened to it? Didn't I help treat wounded soldiers before? Doctor Chong has said that if I study medicine, I will have a great achievement!"

"It's good, it's useful, it's useful, it's my brother who said it wrong." Zhao Mengqi surrendered very sensibly and avoided the spread of "war".

Zhao Hui raised the winner's smile, "Hmph, did that come first, the chicken or the egg?"

「……」

Zhao Mengqi suddenly felt a little pain in the wound on his chest.

"Don't ask! Okay, without going on, I go on to say that we all know that an unconceived egg is always just an egg, and that the reproduction of most living beings in the world requires the interbreeding of males and females. ……」

"Therefore, it can be roughly inferred that half of an individual's genes should come from the father and half from the mother, just like the yin and yang fish in the Taiji diagram, and the yin and yang can give birth to a complete life......

"Everyone has both a part like a father and a part like a mother, and through the facts, it can be found that it is possible for each trait to be like a father or a mother, and there is no division such as the father controlling the nose and the mother controlling the eyes, so it is speculated that no matter which side of the gene comes from, there is complete information that controls all the traits, and the pairing of the two sides has a joint effect."

"But which side will act according to the pairing? If both sides agree, it's fine, but if they are different, then whoever is stronger will listen to whom, and if they are the same, then both sides will behave......

After spending a lot of language and expressing his "conjecture" about genes in detail, Zhao Mengqi began to explain the blood type.

"I suspect that there may be three main genes that control blood type, which can be represented by the words heaven, earth, and man."

Well, Zhao Meng enabled Tiandiren to represent ABO.

"According to what I said just now, both parents will provide genes that control blood type, and in simple terms, one party provides a word, so the combination of blood type control is, Tiantian, Tiandi, Tianren, Earth, Earth, and everyone, a total of six kinds."

"However, I guess that among the three genes, heaven and earth are strong, and man is weak, and heaven and earth will only express heaven and earth, so the specific blood type is heaven, earth, heaven and earth, and man......

"When it comes to blood transfusion, in principle, different blood types cannot be integrated with each other, because the sky and the earth are equally strong, then the two cannot be integrated with each other, and there will be rejection, but the "heaven and earth" type contains both, so it is barely acceptable to add a small amount of the two, and the person is the weakest, as a recipient, he cannot bear the first three, but can be integrated into the first three in small quantities as a donor."

"So, in summary, it's best to transfuse blood of the same type, but as a last resort, the 'Heaven and Earth' type can barely accept any blood type, and the 'human' type can be supplied to other blood types in moderation, of course, the actual situation may be a little more complicated, and there may be other types of blood types, which depends on your hard work."

The conjecture on the left and the speculation on the right in Zhao Mengqi's words seem to have no reliable basis, and it sounds like a fantasy, but Chong Taiyi and the others did not have any intention of questioning, but felt extremely shocked, and tried to calm down and taste and digest these contents.

After a long time, Qin Duan muttered to himself a little, "It turns out that everyone has their own set of genes, and they will also reject other genes, so the idea of swapping hands and feet organs is wrong......

Well? Swapping hands and feet?

Is this kid Frankenstein? How do you have such an idea?

It's a talent, you have to be encouraged!

Zhao Mengqi became interested, "Qin Duan, do you mean that you have the idea of swapping people's hands and feet? Listen, maybe I can give you some advice."

Qin Duan had been by Zhao Mengqi's side for a few days, and he was familiar with King Yan's personality, but he was not restrained at this time, but scratched his head a little embarrassed.

"I saw many wounded soldiers with broken hands and feet before, although many of them were saved by the master, but the disability is always bad, and some of the wounded soldiers were injured because of their internal organs.

The master couldn't save it either, so he had a ridiculous idea, if only the limbs and organs of those rebels could be removed and connected to the wounded soldiers, just now after seeing His Highness's blood transfusion magic method, he thought that the blood could be exchanged, then there should be no other problem."

"However, now I understand that blood can be changed because there are only three main blood group genes, and finding the same type can reduce rejection, but the limbs and organs are very complex...... The little one is so whimsical that it makes His Highness laugh."

"Haha, in fact, I think your idea is very groundbreaking and feasible." Zhao Mengqi smiled, but his eyes were very serious, "The spirit of creating new things lies in 'bold conjecture and careful verification', everything I said just now is just my conjecture, whether it is correct or not, it depends on you to verify."

"Speaking of your idea of changing limbs, the human body does reject allogeneic tissues out of the protective instinct, but there should still be some tissues that may have less rejection like blood, or there is a way to eliminate or suppress the rejection, and you can't give up because you think the difficulty is too great, but you should find a way to solve the difficulty."

"Of course, I also admit that this is something that may not be possible with a long period of hard work, but it can be regarded as a long-term goal, and every time you take a step towards this goal, you will be improved a lot by the process of this effort."

"Then, when the allomorphic connection is still far away, can you try to achieve the self-continuation first, for example, if a person's hand has been cut off not long ago, and the severed hand has not yet died, can you take it back again?"

"Essentially, this is also a kind of suture, but it is many times more complicated, skin, muscles, tendons, bones, blood vessels, etc., each tissue needs different coping methods, these are worth your research and exploration, well, if you have an idea, although it can't be easily tested on humans, you can use animals! Pigs, sheep, dogs, monkeys, and even rats all have similarities with the human body."

Qin Duan's eyes lit up after hearing this, and he seemed to have found a goal in life, and he was eager to try, "Thank you, Your Highness, for your advice, Your Highness's words woke up the person in your dream."

Whether it is autologous continuation or allogeneic transplantation, Zhao Mengqi feels that he will not see it again in his lifetime, but as long as the relevant people keep going, these medical technologies that benefit mankind will definitely appear in this world many years in advance.

"Fourth brother, I also have a doubt." The little clever ghost Zhao Wei actually listened very carefully just now.

Zhao Mengqi thought she was joking, so he said casually, "What doubts? Let's see if we can stump your fourth brother."

"According to what you said, then there are at least two genes that control men and women, but just now you said that genes work in pairs, and there are at least three combinations of two genes, so why are there only two types of genes for men and women?" Zhao Hui looked serious.

Zhao Mengqi was stunned, he didn't expect his princess sister to really ask a very "academic" question, so he had to think about it seriously.

"Well, let's say there are two genes that control male and female, then in terms of the words day and month, the combination has the sun and the moon, and the moon and the moon, but in fact there are only two combinations, why on earth?"

Zhao Wei smiled slyly, "Fourth brother, are you stumped by me?"

"How is that possible?" Zhao Mengqi also wants to save face, "Let me think about it."

"There is a possibility, the so-called life two, in fact, there is only one sex gene at the beginning, for example, it is the month, and all individuals are the moon, but I also said just now that the genes will not only recombine, but also mutate, and the day is mutated, so the combination of the sun and the moon is born, and then it has always been the sun and the moon and the moon match, so naturally there will always be only two Z.br>......."

Zhao Mengqi racked his brains and finally made up a trick that could barely fool the past.

Zhao Wei bit her fingers thoughtfully, "Although your statement seems to be a bit perfunctory, Fourth Brother, you can also justify yourself, just when you say it right...... So in the beginning, there was a man or a woman?"

It's such a question again, Zhao Mengqi is a little crazy......

Fortunately, it didn't let him suffer for too long, Zhao Hui had a flash of inspiration, and thought to himself, "Men can't have children, if there is a male first, then there will be no offspring, so there must be a female first, haha, in this way, Yueyue represents a woman's genes, and that can only assign a moon base to the offspring."

Because only men can split the two genes of the sun and the moon, that is to say, giving birth to a boy and a girl has nothing to do with women, and it should be the responsibility of men themselves!"

Boy......

This girl actually came to such a scientific conclusion!

Of course, Zhao Mengqi couldn't agree with such a "fallacy and heresy", and couldn't help arguing, "It can't be said that when a man reproduces, he must have released two genes, the sun and the moon, at the same time, just to see which one happens to be accepted by the woman......

"This?" Zhao Wei didn't expect his brother to be so strong, but he couldn't think of a reason to refute it, so he couldn't help but pout, "Okay, even if that's the case, it should be a little more responsibility for men, after all, the decisive gene comes from men."

Zhao Mengqi couldn't cry or laugh a little, but he had to acquiesce, after all, his sister was unhappy, and he had to coax herself.
