Father John was a little unlucky. He failed in matching twice in a row. He didn't even say that he had two right-hand assistants, but he also made himself depressed.

"What's going on? My blood is poisonous?" Father John was puzzled.

However, it has to be said that Father John is a cruel man and very adventurous.

Failed both times? Then the third time!

After making up his mind, he looked at the last one, the third assistant, gloomy.

I didn't scare my buddy to death, my eyes turned green. No, my eyes were originally green.

He plopped down to John, "Sir, I'm not ready to see God!"

After hearing this, John frowned fiercely, "My dear servant, your heart of Tao... is not pious enough!"

Well, if you follow the local customs, your faith has changed your mind.

When the servant of God heard this, he cursed in his heart, and I said to you, your uncle's heart!

His eyes glared, "Master, I decided not to believe in God, and I will turn to the Lord of Tao. Your Tao heart cannot control my Tao heart!"

Ga?

John was stunned, is this OK?

But, if you don’t believe it, can’t you! If you don’t believe in God, how can I do this experiment?

He discussed, "Why...my dear servant, can you believe in the Lord later?"

"No!" The divine servant didn't shake his head, "I won't see Daojun later."

"My dear servant, but you cannot abandon me! You are my slave, and you must listen to me!"

God servant, "We are now the people of the Song Dynasty. There are no slaves in the Song Dynasty, but just employers. You are just my employer!"

John: "..."

The old face was pulled, there was nothing I could do. I couldn’t go to King Ning to change the laws of the Song Dynasty, right?

Looking at the servant of God, I wish I could bite him to death.

The more I thought about it, the more angry I became, the more angry I was helpless, and finally gritted my teeth:

"That priest is here to be this blood-inducing person. You can give me a blood transfusion, right?"

Old John went crazy and took his life.

When the servant of God heard this, it was not impossible, but after all, the master and servant were unable to bear it for so many years.

"My dear priest, no! If you die..."

"No!" John was very sure.

"Since my blood is already poisonous, it is possible that I will not die."

John has a strong logical thinking. I have poisonous body, so I don’t have to worry about the poisonous body of the God servant!

If there is no poison in his blood, maybe he can cure the poison in my blood!

So, under the tyranny of the priest, the third experiment began.

As a result, it's okay! The blind cat met a dead mouse.

John and the servant of God's blood matched together and were safe and sound.

John, who was so scared that he was almost urinating, finally concluded, "God bless me, my blood transfusion therapy is indeed effective. But..."

Looking back at the divine servant who had just given John blood, the guy was crying.

"My God, my Sanqing Daojun, it turns out...is there is also a very poison in my blood?"

"God...Daojun...Save your believers!"

Well, he felt that there was a high possibility that there was toxicity in his blood.

Seeing his pitiful appearance, John did not forget to come forward to comfort him, "Don't worry, if it's poisonous, God will give us a way to detoxify."

That's it, but Father John's tragedy began.

It was no small matter that both the master and the servant were "poisoners". Within two days, this matter spread in Zhizhiyuan.

From then on, John's courtyard was ten feet in a radius and no grass grew.

Not to mention living people, dogs can't come.

Later, the whole city knew that the two green-eyed "charlatans" were poisonous people. John went out to eat a bowl of potato flour and no one sold him.

After Zhao Wei learned about John's secret experiment of blood transfusion, he rushed to John's residence and scolded him, and explicitly prohibited him from studying the topic of blood transfusion.

And the names of the two innocent dead divine servants were engraved on the rockery where Zhizhiyuan entered.

However, John was still very persistent, "I am quite unlucky! But don't worry, I will definitely find a way to detoxify."

"You can help me!"

Zhao Wei rolled his eyes. This was not something Father John could study and understand.

Later Zhao Wei once read a video spectrum about rh negative blood, which is known as "panda blood". He thought it was quite novel at the time, so he left some impression.

There is also a simple introduction to the normal ABO blood type, which roughly means:

The serum of different people has a coagulation effect on red blood cells of different blood types.

For example, the red blood cells of passerby A are placed in the serum of passerby B. If the blood types of two people are the same, or A is type O blood, there will be no condensation. If the blood types are different, or A is not type O blood, the red blood cells will be in a condensation state and will not fuse evenly with the serum.

The earliest blood type determination was to obtain four groups of polymerization results through the fusion of serum from different people with different red blood cells, and finally determine the four common blood types.

That is the A, B, O and AB blood types in our later generations.

Although Zhao Wei probably knew what was going on, it was another matter to ask him to tell him about this thing.

Not to mention whether he could explain clearly or not, whether John could understand it is a big question.

For a person who has no cognition, unless you do it for him to show it.

But, how to do it?

Without a centrifuge to separate plasma and serum, without a microscope, John can't do it well without a microscope, right?

So, don’t think about this. It’s not that Zhao Wei doesn’t want John to study the method of blood transfusion. Of course, he thought, and especially wanted it.

Personally, everyone understands the importance of blood type identification and blood transfusion to battlefield medical treatment. The overall advancement of medicine is also an important step.

Also centrifuge? microscope?

Zhao Wei dared not even think of these things. What a cutting-edge technological product? Zhao Wei didn’t know the principle, it was too far away.

Let’s be realistic. It’s good to study the catapult for me first.

Seeing that Old John was scolded by him, he looked decadent and a little unbearable. After all, his spirit of exploration is worthy of recognition.

"Okay!" Zhao Wei said softly, "Let's go back and give you the two dead servants a pension. If you have the chance, you can help them bring them back to Venice."

When Old John heard this, he was extremely moved, "Thank you, Your Highness!"

"What are you grateful for!" Zhao Wei was speechless. The master and servant were pitiful enough. "Have you eaten for a few days?"

The servant next to him immediately replied, "Two days. The evil cook in the backyard did not deliver us food, saying that we were poisonous."

Old John also said, "Your Highness, can you help us buy two steamed cakes? I'm indeed... hungry."

"Oh!" Zhao Wei sighed, "You said this is a mess. Let's go, I'll take you to have a good meal."

The master and servant were taken to the backyard of the Shuai Mansion, and the kitchen made two large bowls of mutton noodles.

He moved Old John, "Your Highness, regardless of the huge poison we were poisoned, was willing to give us food to accompany you... John is grateful..."

"Stop and stop!" Zhao Wei couldn't listen, "It's so toxic!"

Organize your language well, "Say that, your blood is not poisonous. But your blood cannot be easily lost to others."

"For some people, it may be a good medicine. But for another person, it is a huge poison. Similarly, my blood, his blood, and the blood of all people in the world are like this. It is only useful to certain people. It is useless to others, and it will even kill people."

Looking at John, "I have read your blood transfusion method. It is still very good, simple and effective. As long as you strictly control one person and clean it well, it is still very valuable."

"But the problem now is that we can't determine who your blood is medicine to and who it is poisonous to. Do you understand?"

"Ah!?" John was froze there, and he forgot to chew the powder in his mouth. "Your Highness also knows blood transfusion therapy?"

Zhao Wei was speechless and said perfunctorily: "I understand a little bit, and I have also studied it before."

John said anxiously: "Then is there no way to determine whether the blood is poison or medicine?"

Zhao Wei shook his head, "Now you basically don't have to think about it, because the tools needed are too complicated."

"What tools do you want?"

Zhao Wei, "Two types are needed, one is called a centrifuge."

"What is a centrifuge?"

Zhao Wei thought for a long time, "How to say it is a machine that can rotate, and it rotates very quickly and quickly. Put human blood into the machine and turn it together, and use the force of swing to divide the blood into two parts: clear and turbid."

If you can turn... you have to turn quickly...
