Manbao fell silent, and the old lady looked at Dr. Zheng and others with sincere eyes.

Doctor Zheng coughed lightly and explained softly: "This blood transfusion is recorded in some books, but whether it is the person who received the blood transfusion or the person who donated the blood, the number of deaths in the end was quite large, so..."

Seeing everyone's expressions change, Man Bao immediately explained: "That's because those people don't distinguish blood types, and how can you collect blood from one person? There are so many people in the world, and there are only so many blood types coming and going. How can we collect blood?"

Just a few people.”

"How does Doctor Zhou know that there are only several types of blood in the world? Isn't all blood the same? How can we divide it?"

"Is now the time to discuss this? Aren't we talking about blood transfusions?"

Man Bao finally thought of the words to explain, turned to the old lady and said: "The reason why we don't use the blood of our loved ones is because of blood."

Manbao raised his sleeve to show the old lady the blood on it, and said: "You know, there are many things in the blood. You also said that the blood of close relatives blends together, which means that there are many things in the blood.

Something similar, right?”

The old lady nodded blankly, she understood this.

"These things are both good and bad. The bad ones are the source of the disease. Once it enters the body, it may combine with the original source of the disease in the body, or attack the recipient of the blood transfusion alone. This disease is very serious.

, so they often can’t be saved.”

The old lady thought about it for a while, and found out that she understood some of it, but also didn't understand some of it.

The prince on the side asked, "The blood of a close relative has such a disease, but doesn't the blood of other people have such a disease?"

"Yes," Man Bao said, stroking his palms: "This is the reason why we do not transfuse the blood of our close relatives. If you think about it, the blood of your close relatives is so similar to your own, and naturally even the source of the disease is similar. This is like someone who entered the hospital.

When you walk through your own door and see that it is your brother, you turn around and ignore him, and your body will let go of the source of the disease."

"But if a stranger's blood enters your body, it will be like a stranger entering your door. You will look at it and be on guard. Once the source of the disease is found, a barrier will be raised in the body to kill the source of the disease, and then only the good ones will be absorbed.

That part." Man Bao finally explained clearly, and took a long breath and said: "That's it, so you guys take a look, just pull some people to draw blood for me, and I'll see whose blood type it is first.

If it’s appropriate, I’ll draw someone’s blood soon, without using the blood of a close relative.”

Man Bao's metaphor was easy to understand, and the old lady and the beautiful woman beside her also understood it.

So the two of them looked at the servants at home.

The prince said thoughtfully: "I understand, it's better for this stranger to have a grudge against Sanlang, so that he can discover the source of the disease in the blood more quickly. Hasn't Du Yu come here yet?"

Man Bao: "...Your Highness, you may have misunderstood me. The body can only distinguish the source of disease in the blood, but not a person's face."

The prince glanced at her and said, "I don't think so. Everyone's blood is different. His appearance must also be imprinted in the blood."

As they were talking, the imperial guards brought a man in. He was not restrained, but they were attacking him from both sides, and his face was ugly.

A person followed hurriedly behind him. As soon as the person came in, he trotted forward and saluted the prince from a distance. Then he bowed his head to the old lady with an apology on his face, "Old lady, I am really ashamed. Du Shu is so ashamed."

I finally met the old lady and my siblings."

The old lady pressed the corners of her eyes and said, "This matter has nothing to do with Dalang. I'm old and can't take care of these things. I just want my children to be safe and healthy."

Du Shu immediately asked: "I don't know how Sanlang is doing. He, if something happens to him, I will definitely beat him to death to pay for Sanlang's life."

This is just a nice thing to say. Du Yu is his biological brother, how could he be willing to let it go?

The old lady wiped her tears and sat on the stool without speaking.

The prince said coldly: "It's good that Du Dalang has this intention. It just so happens that he has lost too much blood and is lying on the bed. He needs a blood transfusion. The doctor just said that blood from close relatives cannot be transfused. There are many vulgar people in this mansion."

, how can their blood be worthy of entering Sanlang's bloodline? So Gute asked Du Erlang to give it a try."

Du Shu was shocked and asked: "Blood transfusion? Isn't this the witch doctor's method? Your Highness, is this possible?"

Du Yu snorted coldly and said: "His Highness just said it if he wanted to take my life. Why make such excuses? Who doesn't know that blood transfusion is a quack method?"

Man Bao, who had been standing quietly and listening, couldn't help it when she heard this. She raised her head and glared at Du Yu, saying who is a quack? You are the quack.

Man Bao opened the box directly, took out a white vessel from inside, then took a short needle and stepped forward. Ignoring the prince who wanted to argue with Du Yu, he directly took Du Yu's hand and quickly touched his finger with his eyes.

The tip pricked it a bit.

Du Yu stretched out his hand to shake off Man Bao's hand, but the prince shouted: "Hold him down!"

The Imperial Guards immediately suppressed Du Yu from the left to the right.

Du Yu struggled, "Let me go!"

Du Shu couldn't help but took two steps forward and shouted: "Your Highness!"

The prince's face was as dark as water.

Du Shu then turned back to see Mrs. Su. The old lady covered her face with a handkerchief and seemed to be crying sadly.

Man Bao had already taken out a drop of blood from his fingertip, and threw it away without bandaging it. She said: "What are you afraid of? Just take a drop of blood. Also, I am not a quack doctor!"

Man Bao handed Doctor Zheng a small vessel and said, "Go and get some of the patient's blood. I want fresh blood."

After that, he handed him a new short needle.

Bai Shan finally saw the short needle clearly now. He felt that these things looked very familiar. When he saw it, his fingertips still felt faintly painful.

He looked at Man Bao in shock.

Man Bao was putting things out one after another, and when he turned to meet his gaze, he lowered his head with a guilty conscience.

Dr. Zheng quickly took out the blood. Man Bao first identified the patient's blood type. When he saw that it was the same blood type, he put a label on him. Then he tried Du Yu's blood type and found that it was also the same type.

She immediately became happy and looked at Du Yu who was still being held in custody happily, "This must be a special fate. Your blood types are the same, so you can lose."

Du Yu's eyes widened and he shouted: "How dare you say that you are not a quack doctor? How could my blood be the same as Su Jian's? I am not his blood relative."

Man Bao took out the packaged things from the box and said happily: "Who said that only the blood of blood relatives is the same? There are several types of blood in the world. Think about how many people there are in the world."

Du Shu didn't want to think about his brother's blood being drawn. His mind was racing and he asked: "You said that, doesn't it mean that the blood of many people in the world is fused?"

"good."

"Then how can we shed blood to recognize our relatives?"

Man Bao said: "You still believe this? You should have told me earlier. It's very simple. Come and get a basin of water."
