After a few scoldings and step-by-step professors, these military doctors finally mastered the blood type separation technology.

Of course, they are still muddy about the principle. But this is not important anymore, as long as they understand these four blood types.

A military doctor was ingenious: "Your Highness, what are you talking about a and b? The villain is really confused. Why not use the four symbols of the blue dragon, white tiger, vermilion bird, and black trunk instead, or use the four seasons of spring, summer, autumn and winter."

The meaning of English letters is a bit difficult for these military doctors. They don’t know what abcd is at all.

But as they said, calling type A blood into blue dragon blood or spring blood is even more inconsistent for Zhu Cilang.

"No, I ask you to remember it, so I will remember it honestly for me. a, b, ab and o, each of you memorizes these four blood types a hundred times, but you can't eat."

Several military doctors looked at each other, and the Crown Prince gave orders, but they dared not refuse to obey. Fortunately, although everyone was puzzled, they were not too strange.

Because in the Ming Dynasty, it is normal to create characters.

Why do you say that? There are regulations on naming descendants of the royal family of the Ming Dynasty. The regulations are too weird, and the descendants of later generations can only create characters.

Zhu Yuanzhang, the Emperor Taizu of the Ming Dynasty, was a parenting expert. Zhu Yuanzhang gave birth to twenty-six children in total. In addition to the youngest child, twenty-four were enfeoffed as vassal kings.

As a result, in the late Hongwu period, there were hundreds of descendants of the Ming royal family. After Zhu Yuanzhang discovered that there were too many descendants, in order to prevent the random naming caused chaos, he formulated a strange naming rule for his descendants.

Among the five elements, there is the theory that "wood produces fire, fire produces earth, earth produces metal, metal produces water, and water produces wood".

So in order to avoid trouble for future generations, Zhu Yuanzhang had already made this character with five elements for his twenty-four sons and descendants of the vassal kings. He just needed to name one by one according to regulations.

It is logical that he gave more than 20 names to his descendants, which should be almost enough, but he never expected that such a situation would occur in his later generations. He stipulated the order of naming descendants by using "gold, wood, water, fire and earth". For example, Zhu Yuanzhang's son Zhu Biao, and Yan Wang Zhu Di were all next to the character "Mu", so the grandson's generation was next to the character "Huo". For example, Zhu Di's sons Renzong Zhu Gaochi and Han Wang Zhu Gaoxi, we will find that Zhu Gaoxi was not next to the character "Huo", because in ancient times, there were not four dots of water under the character "Xi", but the character "Huo" was the base.

With so many sons, there were even more grandchildren. In the middle of the Ming Dynasty, the number of royal children increased to 10,000. In the late Wanli period of the Ming Dynasty, there were 80,000 descendants in the Ming Dynasty. From twenty-four vassal kings and one emperor, 80,000 people were able to be derived after hundreds of years. I have to admire the fertility of the old Zhu family.

Otherwise, some people say that it was the Ming Dynasty royal family that dragged down the Ming Dynasty, because most of these royal children were just waiting to die and needed to be raised by the country.

The ancestors have regulations that you cannot rename the name and must also have the five elements. There are so many royal children, there are more people than words. What should I do if my naming is not enough? Then I have to create my own characters.

For example, "Zhu Gongxi, Zhu Shenlei, Zhu Tongchromium, Zhu Tongniobium, Zhu Anmercury, Zhu Zai sodium, Zhu Jun iron, Zhu Cheng cobalt, Zhu Cheng palladium, Zhu Enso, Zhu En copper, Zhu En cerium, Zhu En potassium, Zhu Shuai zinc, Zhu Lanthanum", these names actually become the periodic table of chemical elements.

The real periodic table of chemical elements in history was transliterated based on the names of the royal children of the Ming Dynasty.

As an enlightener of modern Chinese chemistry, Xu Shou, a scientist in the Qing Dynasty, made outstanding contributions to translate Mendeleev's periodic table of elements. However, in Russian, the element names could not be found in suitable Chinese characters at that time.

Because first, we need homophones, and then it is best to make the Chinese character composition that can explain the characteristics of this element well, and radicals can represent the normal state of this element. So he thought of the name of the royal family in the Ming Dynasty, turned it over and saw that it was just right.

Therefore, these words created by the royal family have become the periodic table of chemical elements we see now.

The popularity of character creation made Zhu Cilang create a blood type relationship between these four letter combinations. Therefore, after thinking about it, these military doctors no longer care about it.

After mastering the principle of blood transfusion, the more than 300 wounded soldiers in Yizhou City alone had blood transfusions to them.

There is no infusion tube, so you can only use a thin bamboo tube or reed instead. It means inserting a reed tube into the arm of a living person and then inputting it into the injured person's body. It looks extremely strange, but countless living people are alive.

More than 300 wounded soldiers were rescued, and more than 170 people were rescued. In addition, the causes of the death of the wounded were mostly caused by infection.

You should know that most of the survival rate is a miracle. It would be great if the number of seriously injured people with more than 300 people can survive dozens of them.

Li Shouyan, who was blood-brushed, was still unconscious, but his pulse was getting stronger and stronger, and the blood on his face gradually recovered.

Yuan Xiaoxiao was guarding his sickbed day and night, and sometimes she didn't often wipe his forehead with a towel, and sometimes she didn't often touch his pulse. But seeing Li Shouyan's breathing gradually stabilized, she couldn't help but feel surprised.

After dawn, Yuan Xiaoxiao, who couldn't stand it, finally fell asleep in front of the bed.

The first ray of sunshine in the morning spread into the room. Li Shouyan slowly opened his eyes, first there was a white spot in front of him, and then to the hazy room.

When she tilted her head, she saw a beautiful woman lying on the edge of her bed and was sleeping deeply. Under her long eyelashes, she was very moved. She was really beautiful. Especially when she was asleep, she was even more beautiful.

Yuan Xiaoxiao was sleeping very heavily. Li Shouyan raised his arms vigorously and gently stroked her hair. As he lowered his head, he saw that Yuan Xiaoxiao's arm was bandaged with gauze. In an instant, Li Shouyan seemed to understand something. Could it be that she gave me her blood?

Just as she was thinking about it, Li Shouyan raised her hand and woke Yuan Xiaoxiao up. The moment she opened her eyes, she saw that her complexion was restored and she could already move towards her.

Yuan Xiaoxiao screamed, threw herself into his arms, and burst into tears.

Li Shouyan patted her lovingly and gently: "It's okay, it's okay, I can't die. Miss Yuan, you must be worried about it being broken."

Yuan Xiaoxiao cried even more...

The door creaked open, and the pretty starling Yan Yishuang walked in with a bowl of hot porridge. Seeing the scene of the two of them, she felt a little embarrassed and wanted to quit.
