Xiu'er's feeling is right, although Lin Ping'an's body is only twelve years old, that soul is already an adult who is dozens of years old, so it is inevitable that he will be a little old-fashioned when he speaks and acts, which is very inconsistent with the identity of a twelve-year-old boy.

At this point, Lin Ping'an didn't realize it himself, but in the eyes of others, this is a little abnormal.

Hearing Xiu'er's words, Ye Yunshu condensed his eyebrows and thought about it, and also felt a little strange.

"But he is obviously from the same village as Uncle Wang and Zhao Sheng!"

She thought to herself, "But why do you look like an adult?" ”

Ye Yunshu shook his head, feeling incomprehensible.

On the second day, Batu came to Lin Ping'an early in the morning.

"Little sir, let's go to the Tai Hospital today, the big man has an order, and I want you to teach the blood exchange method,"

Lin Ping'an nodded, he had already thought of this, so he turned around and went back to the house to pick up the small box, and followed Badu out of the door.

Too in the hospital.

At this moment, it was already full of people, and everyone was looking forward to it, waiting for Lin Ping'an's arrival.

It's really that the blood exchange Dafa is too incredible, in the eyes of these people, it belongs to the long-lost ancient secret method, I have heard but have never seen it.

If it weren't for Lin Ping'an casting this Dafa in front of so many people, almost no one would dare to believe that there really was such a Dafa in this world.

A moment later, Batu and Lin Ping'an walked in, and everyone looked at the eleven or twelve-year-old boy, each with a complicated expression.

"This kid is obviously only eleven or twelve years old, can the matter of the medicine god's manifestation be trusted?"

Someone muttered quietly.

"But he saved Dolgon with the blood exchange method, and many people were present at the time, which is absolutely true."

"The Great Law of Blood Exchange? Hehe, that's only seen in classical cheats, and no one has ever used it in reality. ”

Although Batu once depicted the scene at that time, when he really saw Lin Ping'an, the child, everyone had an unreal suspicion in their hearts.

"Hey, don't make any noise, won't you understand in a while?"

Batu cleared his throat and said to the crowd:

"Dahan has a life, so let me and others in the Tai Hospital learn the blood exchange Dafa from Mr., don't be impatient, you need to study carefully, be sure to learn this method!"

Speaking of this, he nodded at Lin Ping'an.

Lin Ping'an looked around, and saw that there were twenty or thirty people in this room at this moment, including full people and Han people, he nodded at everyone, and was about to speak, but he heard a commotion outside the door, and then a person slowly walked in.

"Four Baylor!"

Someone shouted, and I saw Huang Taiji walking in slowly with Fan Wencheng, followed by a team of armor soldiers.

He glanced at everyone expressionlessly, but Fan Wencheng behind him waved his hand and said:

"Only the Manchurians are left here, and all Han people have withdrawn."

Hearing this, everyone's expressions were abrupt, and several Han imperial doctors hurriedly stood up, bowed to Huang Taiji, and ran out with their heads down.

"The Dafa of exchanging blood is the manifestation of the god of medicine, and the heavens are auspicious to my gold, and it must not be leaked, if someone reveals it, there will be no forgiveness!"

Huang Taiji shouted coldly at everyone, and everyone knew the reason, and a cold sweat suddenly broke out on his body.

Seeing that all the Han imperial doctors had retreated, Huang Taiji sat down, waved his hand at Lin Ping'an and said, "You can start." ”

I didn't expect Huang Taiji to be so careful, it seems that he is really a powerful character...... Lin Ping'an saluted Huang Taiji, and then said:

"The Great Method of Blood Exchange is what I obtained by encountering the God of Medicine in the mountains, and this method can cure people who have lost too much blood, but not anyone's blood can be poured into the injured person's body."

As he spoke, he opened the small box, and continued:

"There are several types of blood in the human body, and only those of the same type can be transfused to each other, otherwise they will die directly due to blood clotting."

Speaking of which, he took out the blood type test paper in the box and said:

"Look, this thing is used to test the type of blood, and different types of blood will show different colors on it, so you can tell if the blood type is the same between the recipient and the recipient."

"Is that understandable, sir?"

Batu raised his hand and said, "Bumu Butai's blood and Dolgon's blood are of the same type, and Azig's blood and Dolgon's blood are different types?" ”

Lin Ping'an nodded: "That's right." ”

Only then did everyone suddenly realize that they looked at the stack of test papers in Lin Ping'an's hand.

"But sir, how do you get such test strips?"

An imperial physician asked in a loud voice.

"This is left by the Medicine God, and when it runs out, it will be gone."

Lin Ping'an said that he spread his hands, he was also a little helpless, this kind of test paper can't be made in this era, so he can only say so.

Hearing this, bursts of boos erupted from everyone's mouths.

Batu shouted: "In other words, when these test strips are used up, the blood exchange Dafa can no longer be implemented?" ”

Lin Ping'an thought for a while and said:

"Not really. I remember that Yakushin-sama once told me that if the contents of the box run out, you can replace it with a simple method. “

Hearing this, everyone immediately relaxed, even Huang Taiji stared at Lin Ping'an with interest, Fan Wencheng on the side frowned, and his face showed a trace of solemnity.

"The god of medicine said that the simple way is to mix the blood of the recipient with the blood of the blood giver to see if there is a fusion between the two, if it cannot be fused, it means that the blood of these two people is not of the same type and cannot be exchanged, but on the contrary, it is okay."

When the words fell, someone immediately shouted: "Recognize relatives by dripping blood, this method is known." ”

Lin Ping'an shook his head and said: "It is not credible to recognize relatives by blood, all human blood will be fused in the water sooner or later, it is just a matter of time." “

With that, he beckoned to Badu.

I don't know why, I walked forward, and Lin Ping'an said:

"Let's do an experiment."

Speaking of this, he asked someone to bring a bowl of water, took out a needle and pricked his finger, squeezed a few drops of blood into the bowl, and then pricked Badu's finger and dripped a few drops of blood into the bowl, and then said:

"There's a way to make anyone's blood come together quickly."

With that, he took out the alum he had prepared from his bosom and melted it into the water, and a moment later, the blood droplets in the bowl fused together at a speed visible to the naked eye.

Unable to see this scene, everyone showed expressions of disbelief.

Lin Ping'an and Ba are obviously not relatives, how can the blood of the two be fused together?

It's impossible!

Seeing everyone's expressions, Lin Ping'an smiled:

"If you don't believe it, you can all come up and try it."

Immediately a few people walked up and pricked their fingers and dripped blood into the bowl.

A moment later, there was a sound of surprise from everyone's mouths, and in their eyes, all the drops of blood quickly merged together.

What's going on?

Everyone looked at Lin Ping'an with blank eyes, feeling that their cognition had been greatly impacted.

"Everyone has already seen that I just put a few drops of alum in the water, and it has such an effect, in fact, if it takes long enough, these blood will also mix together, so it is not credible to say that the blood is identified."

After Lin Ping'an said this, everyone suddenly let out an exclamation.

"How is this possible?"

"Dripping blood to recognize relatives is a method that has been passed down from ancient times to the present, Mr. Xiao's words are really a bit incredible."

Seeing that everyone didn't believe it, Lin Ping'an took out a small bottle from his arms again and said:

"Actually, I can make the blood not mix."

With that, he took out another vial from his bosom, dropped a few drops of clear oil from the bottle into another bowl of water, and motioned for everyone to try it again.

Several of the Imperial Physicians pricked their fingers again, dripping blood into the bowl, but this time, to their astonishment, all the blood no longer fused.

"As you can see, as long as the clear oil is dropped into the water, the blood will not fuse again, so it is said that the blood can be artificially controlled."

Hearing this, the room suddenly exploded, and Lin Ping'an's conclusion was like a bomb, which blew everyone up.

The method of dripping blood has been passed down for many years from ancient times to the present, and it has been deeply ingrained in the hearts of everyone, and it is really difficult for them to accept it when it is suddenly overturned at this time.

Badu scratched his head and exclaimed, "Then, according to the gentleman, how do you determine the type of blood?" ”

"It's actually quite simple."

Lin Ping'an said as he took out a piece of glass, and then said:

"As long as the blood of the recipient is dripped on the glass, not in the water, and the blood of the donor is dripped on it, as long as the two are combined, it means that the type should probably be the same."

Everyone looked at the glass in Lin Ping'an's hand and seemed to understand, as long as it was not in the water, if the two drops of blood fused, it meant that the blood type of the two was the same.

Of course, there may be an error, but the probability is small, and if it does occur, it will be left to fate. ”

Lin Ping'an added that he was actually a little helpless.

Because this method is obviously a bit sloppy, in the words of later generations, it is easy to cause medical accidents, but at this level in this era, there is no way to have so many rigorous methods and means like later generations, so it can only be like this.

Hearing this, everyone nodded slowly and seemed to understand.

Although glass is also more precious in Daming, it is not impossible to find it, and then it is easy to put a piece of such glass in the military doctor's box.

"When I see my husband's blood transfusion, the silver needles and tubes are very special, can I equip a large number of them?"

Batu asked.

This is what Lao Tzu brought from modern times...... Lin Ping'an shook his head and said:

"The silver needle I use is hollow, I wonder if there is a skilled craftsman who can make it?"

After saying this, he took out the set of blood transfusion equipment in the box and put it on the table.

Everyone hula gathered around, watched carefully, and couldn't help but let out a sigh of exclamation in their mouths.

But after a moment, everyone shook their heads, and a look of regret appeared on their faces.

In fact, the needles used for modern blood transfusion are thin and small, and they are hollow, and they cannot be made at all in this era.

Fan Wencheng stepped forward, picked up the silver needle and put it in front of his eyes to look at it carefully, turned his head to Lin Ping'an and asked:

"Can I replace it with something else?"

Lin Ping'an thought for a while and said: "Fang Ran can, but just make the needle bigger, although it will make people feel uncomfortable when transfusing blood, but it can barely be used, of course, it can also be replaced by other materials, such as bamboo." ”

In fact, these are all imagined by Lin Ping'an out of thin air, as for whether it can be realized, he is really not sure at all.

Fan Wencheng nodded, picked up the blood vessel and put it in front of his eyes to look at it carefully, with a hint of surprise on his face that could not be concealed.

Modern blood vessels are not only transparent, but also very thin and soft, which is simply incredible in Fan Wencheng's eyes.

At this moment, Huang Taiji also stepped forward, took the blood vessel from Fan Wencheng's hand, looked at it for a long time, and sighed:

"Sure enough, it is the manifestation of the god of medicine, and there is probably no mortal who can make such a delicate thing except for the immortals."

There was a hint of awe in everyone's eyes, and the eyes that looked at Lin Ping'an were full of envy.

"Mr. Fan, can this tube be replaced with something else?"

Huang Taiji asked at Fan Wencheng.

Fan Wencheng thought about it, but asked Lin Ping'an: "Can you use the small intestines of animals instead, such as sheep intestines?" ”

Fan Wencheng really has enough brains..... Lin Ping'an had already guessed at this moment that this young Han man must be Fan Wencheng, the founding minister of the Qing Empire, and couldn't help but admire him greatly.

The plan of replacing modern blood vessels with sheep intestines was also what Lin Ping'an thought of before coming here, but he was not sure whether it was feasible.

Huang Taiji took Lin Ping'an's small box, rummaged in it for a while, and then closed the box, and then said:

"Since these things are given by the God of Medicine, they can't be wasted at will, I will give this box to Father Khan and leave it in the palace for emergencies."

Lin Ping'an was not surprised at all, since the method of blood transfusion had been taught to everyone, the box naturally could no longer belong to him.

Huang Taiji looked at everyone and said in a deep voice: "This method must be mastered, and when the silver needle and blood vessels are out, it will be popularized in my Dajin army." ”

Everyone nodded in agreement, but listened to Huang Taiji emphasize again: "This law cannot be passed on to the outside world, today the register has been recorded, if someone leaks out, it will be a capital crime!" ”

Everyone looked stunned and nodded one after another.

After a while, Huang Taiji looked at Lin Ping'an's back and asked in a deep voice, "Mr. Fan, what should I do with this son?" ”

Fan Wencheng smiled and said: "The sticky pole has already had a comprehensive understanding of this son, it is an ordinary person in Ningyuan City, and the Dolgon brothers swore to him as brothers of the opposite sex, and gave him gold and silver, and bought a house and slaves in Shengjing City, it seems that he wants to live in this Shengjing City for a long time." ”

Hearing this, Huang Taiji nodded, but his brows were furrowed, and he suddenly turned his head to stare at Fan Wencheng and said:

"Mr. Fan, do you really believe in the theory of the manifestation of the medicine god?"

Fan Wencheng was stunned for a moment, and then smiled bitterly: "I have also thought about this matter, but after all, Lin Ping'an is only a twelve-year-old child, how can he explain it?" ”

Huang Taiji shook his head and said slowly: "I see this son as a young man and an old man, even in front of me, he can treat him normally, talk eloquently, without the slightest restraint and fear, if he is just a child of ordinary people, I don't believe it." ”

Hearing this, Fan Wencheng lowered his head and pondered, and after a while, he raised his head and said, "If the Sibeile Cave is a fire, there must be a secret hidden in this son. ”

Huang Taiji looked up at the sky, and only after a while did he say: "I don't know if there is a secret, but I can be sure that this son must be very human." ”

Fan Wencheng's face showed a solemn expression, and he already had a plan in his heart.
