It is really helpless to be limited to the royal family.

But the Li royal family...although there are many people, the vast majority have been transferred from Chang'an City.

This is of course to prevent the possibility of Xuanwu Gate again.

Therefore, Chen Zhengtai thought about it and had to go to find the concubines.

But even the concubines... cannot be tested at will. At least it must be at the level of the imperial concubine. After all, how can people with ordinary family backgrounds deserve Li Shimin's noble blood?

The ancients paid great attention to this. Even if they died, they would never allow their blood to be defiled.

Chen Zhengtai roughly tested it and found that Li Shimin's blood was type A blood. Chen Zhengtai tested others several times, but the results were not very ideal.

Especially other imperial concubines, they heard that they wanted to get blood, and their faces were pulled down one by one. After finally collecting blood, they were still difficult to find Li Shimin's blood type.

This made Chen Zhengtai a little annoyed. By the way, this type of blood is also a prelude. Looking for this thing is like a loser on weekdays. Whenever you want to find something, it is very common on weekdays, but when you insist on searching for it, you can never find it.

So, there was no choice but to expand the scope, but this was a big trouble. After thinking about it, Chen Zhengtai couldn't help but feel sad.

On the other hand, as Chen Zhengtai's instructions, Li Chengqian took two girls and his mother to clean up a small hall and began to practice.

The practice process is extremely painful.

For example, a pig was shot directly by someone to create a wound similar to Li Shimin. Then it was carried to the side hall and tied the pig up, and then started to take many strange vessels and start to attack.

There was a doctor in the clinic on the side. The doctor had already received a warning that if the matter was leaked, he would have to be missing his arms and legs and fewer people would be missing in the family.

In fact, surgery has become common in the Erpi groove. Of course, most of them are just simple trauma surgery.

But this doctor has never heard of such a surgery. In his opinion... His Majesty has no chance of survival.

Because surgery is popular in Erpigou, a large number of doctors have gradually begun to understand the structure of the human body, and many people even act as coroners and deal with corpses every day. In the eyes of many Erpigou doctors, this is the first step in learning surgery.

This doctor dared not take the surgery himself, after all... for him, such an operation... is not good, that is, the one who wants to kill people, and the emperor is the one who is cured. He has a hundred courages and dare not take risks.

Li Chengqian was already busy. Under the doctor's teaching, he was busy trying to cut the pig's wound with three women at home. Any mistake could kill the pig.

The first thing to overcome is actually a psychological problem. In such a bloody scene, there is no mistake. The most important thing is... everything must be done quickly. The longer the time is delayed, the higher the mortality rate.

Empress Changsun almost fainted when she saw this bloody scene at first, but she thought of Li Erlang, who was seriously injured, but she still forced herself to get angry.

"Can this cure the disease?"

"I don't know, that's what Chen Zhengtai said." Li Chengqian comforted his mother and said, "Don't worry, Mother, Chen Zhengtai's words are quite reasonable. He also said that if it is not cured, he is willing to pay it off with his life."

Princess Sui'an said immediately, "My husband has never said this. He said he is only 10% sure."

Li Chengqian turned around and glared at Princess Sui'an. The look was probably about expressing that Princess Sui'an had a low emotional intelligence and didn't see the orphan comforting her mother? Isn't this unhappy to say this at this time?

Princess Sui'an ignored him and pretended to turn a blind eye, lowering her head to sort out the alcohol and soaking the utensils.

He killed several pigs in a row, but to be more precise, he killed several pigs, and Li Chengqian was exhausted.

Because he found that every pig, without exception, was dead.

It is impossible to let the pig survive.

This made Li Chengqian extremely frustrated, but he wanted to discuss it with Chen Zhengtai, but Chen Zhengtai seemed to be indifferent to it and only focused on the issue of blood source.

The next day, a few more pigs were transported, and the operation had to continue. Dragging his physical and mentally exhausted body, Li Chengqian still took the three women at home to continue the operation under the guidance of the doctor.

With many experiences in the operation, he, Queen Changsun and others finally saw this bloody scene and no longer could not accept it. The hands holding the knife and tweezers were much more stable than before. This operating room was a secret room renovation. Although it was not completely sterile, and after the disinfection of alcohol, many lamps were lit in the secret room. As the lights were lit, it produced a shadowless effect.

But even so, no matter how stable Li Chengqian is, almost no pig can last until the end of the operation.

"Two incense sticks..." A dead pig was sent away, and Li Chengqian wiped the sweat from his forehead. Princess Changle Li Lizhi felt that she was soaked in sweat. She was sobbing in a low voice.

The operation time is much better than before.

The doctor took the dead pig for an autopsy and finally got the result of the operation... This time the operation was more experienced than before, and he almost never touched the heart not far away, and the arrow shaft was taken out perfectly. In addition... the hemostasis, suture, bandaging, and then began to look decent.

"Everything is perfect, so what?" Li Chengqian looked at the doctor and said with deep grudges: "This pig is still dead. If the father was a pig, he would have died many times."

doctor:"……"

Queen Changsun turned sideways and couldn't help but burst into tears.

Li Chengqian looked at his sad mother and looked unbearable, then said, "Let's go ahead, there are a few more today."

But the doctor said, "I'm afraid it's too late to go. Duke Han... No, Mr. Chen said that His Majesty's wound is in danger of purulent. If you delay it, I'm afraid that the gods will be unable to save it."

Speaking of this, whether it is Li Chengqian, Empress Changsun, or His Highness the two princesses, they can't help but feel worried and sad.

In fact, they did not see that such a surgery could save people.

Didn’t these pigs die without exception?

Li Chengqian seemed a little sane, but Empress Changsun calmed down and gritted her teeth and said, "Tie the next pig."

After all, Empress Changsun is an experienced woman. At first, she couldn't stand this scene, but now she wants to save her husband, so she can hold on to anything. If she has any hope, she is willing to continue trying.

Empress Changsun said so, and everyone dared not neglect and continued the surgery over and over again.

Everything has a process from being unfamiliar to being familiar with.

The principle of the surgery is actually not complicated, so the root of the problem is just to try again and again.

Empress Changsun was responsible for suturing and bandaging the wound, Li Chengqian was responsible for the surgery, while Princess Changle and Princess Sui'an started to prepare the utensils and equipment for the surgery.

On the other hand, Chen Zhengtai finally found a blood type that suits Li Shimin.

This is really blind under the light, it seems... I actually have type A blood.

When he got the verified result, he was a little confused.

Then a tragic look appeared on his face. This is... a tragedy.

Zhang Qian has been following Chen Zhengtai, responsible for running around and running back and forth.

When Zhang Qian heard that Chen Zhengtai was about to operate, his Majesty had hope of survival, he was already cheered up.

Perhaps it is just for Chen Zhengtai. His Majesty is gone, and he still has His Royal Highness the Crown Prince.

But for Zhang Qian, Li Shimin is everything about him. As an attendant, no one knows better than Zhang Qian that everything comes from Your Majesty. Once Your Majesty dies, his destiny will be sent to the imperial tomb to guard the tomb. No matter how much His Highness respects him, he will use the eunuchs who used to serve him on weekdays.

Therefore, Zhang Qian now almost treats Chen Zhengtai as his own father. Chen Zhengtai wants to perform a blood test in the palace. He quickly summoned people and told one concubine after another to conduct the inspection.

At this moment, looking at Chen Zhengtai's sad look, he couldn't help saying, "Young Master Chen, didn't you say... Is this blood searching? Why are you still frowning?"

He didn't understand what Chen Zhengtai was at this time.

Chen Zhengtai sighed and said, "I'm looking for it, but it's just a coincidence, it seems to be on me."

Zhang Qian immediately looked at Chen Zhengtai greedily and couldn't help but give her thumbs up: "Young Master Chen is so full of treasures."

Chen Zhengtai felt that this was harsh and difficult to attack.

The next moment, Zhang Qian seemed very sympathetic to Chen Zhengtai: "I just don't know how much blood to be drawn... This is the first time we have heard that this blood is better than someone else's body."

Chen Zhengtai sighed: "A lot, a lot. People say... a drop of semen, ten drops of blood. Today, in order to save His Majesty, I don't know how much essence I will waste."

Zhang Qian nodded in agreement.

Essence, blood, essence, blood, for people of this era, blood is extremely precious. Therefore, people firmly believe that blood originates from innate essence and is generated in acquired diet; the formation of essence is also produced by acquired diet, so there is a saying that "element, blood and the same origin". The profit and loss of essence and blood determine the health of the human body.

If you draw too much blood, I am afraid that Mr. Chen's body will not be able to stand it. It will take at least twenty years of life, and even... I don't know if I can have a baby in the future. If I can't give birth, it would be a pity, so it would be the same as us.

Zhang Qian said a point: "Then will this Majesty still save him?"

Chen Zhengtai gritted his teeth without thinking, and said, "Save, why not?"

Zhang Qian's eyes suddenly turned red and tears were about to burst into his eyes.

In the past, he thought Chen Zhengtai was quite insidious, but now it seems that Mr. Chen is also a loyal and righteous person.

In his values, this is almost equivalent to using Chen Zhengtai's life to exchange for the possibility of His Majesty's survival.

Zhang Qian immediately changed his impression of Chen Zhengtai, and then said with great respect: "Young master...you...hey...I don't know what to say, take care of you."

When they heard that Chen Zhengtai was going to donate blood, and the amount of blood drawn this time might be particularly large, Empress Changsun and Li Chengqian were both shocked.

"Is there no other way?" Empress Changsun was also quite shocked when she looked at Zhang Qian who came to report.

Zhang Qian shed tears and said quietly: "Mr. Chen said that time is too late and he cannot be delayed anymore. He said that since his blood can save His Majesty, he must not... Alas... there is nothing to say now. He is already preparing some new surgical instruments, saying that the faster the surgery, the better. As long as His Majesty survives, even if the blood on his body is drained, he will be happy."

When Empress Changsun heard this result, her first thought was to refuse.

Just kidding, this is also half of my son-in-law, and I have been with me. Moreover, Chen Zhengtai is still young, this is blood. If a person loses his blood, isn't it almost the same as a dead person?

Although Empress Changsun does not understand medical skills, she understands more than anyone else that the preciousness of blood is afraid that if she draws blood, she will become a useless person.

Zhang Qian could not see the hesitation of Empress Changsun, and immediately said: "Empress, Mr. Chen said that he had made up his mind and asked the Empress and Your Highness to seize the time and practice as much as possible. Never make any mistakes. Let's do our best to save Your Majesty no matter what."

"I know." Empress Changsun sighed silently, with tears in her eyes: "In the past, there were always people saying... the emperor was the emperor, who held the power and money of the world. The so-called "all the kings under the world are the kings, and the ministers in the shores are the kings. The ministers please him, and the aristocratic clans also gained benefits from him. Therefore, they all looked loyal and loyal in front of the emperor. But people's hearts are separated from their belly, how can they distinguish between loyalty and treason? Not to mention others,

Even if it is my close relative, the prince's uncle Changsun Wuji, this palace may not ensure that he has absolute loyalty. Your Majesty once wrote a poem entitled: 'The wind knows the strong grass, and the swaying of the swaying of the stern ministers.', which means that only in the wind can you see whether it is a strong and upright weed, and only in the intense and turbulent era can you identify whether it is a loyal minister. Zhengtai's loyalty and filial piety to Your Majesty is really touching."

Li Chengqian also showed that he couldn't bear it.

Princess Changle and Princess Sui'an each frowned, both worried about Chen Zhengtai.

Empress Changsun finally calmed down and said, "Let's continue practicing. We must save Your Majesty, and we must not let Chen Zhengtai bleed in vain."

There seemed to be no better way in front of this. The four of them had reached the point of tirelessness without hesitation.

What is this fatigue worth compared to Chen Zhengtai’s efforts in essence and blood?

By the evening, an operating room had been well laid out.

Chen Zhengtai has also come here with many strange vessels and medicines.

Chen Zhengtai and others went to see Li Shimin first.

Li Shimin was extremely weak on the couch, so weak that it seemed that he had reached his dying moment. His injuries were too severe, and it was thanks to his strong body in the past that he has been able to support it now.
