Li Chengfeng gave everyone a blank look, and said: "Don't be surprised what happens next, because it may subvert everyone's common sense and understanding of human body structure!"

"Well... But, it doesn't matter anymore, it's good that everyone doesn't want to be born anyway!"

"Okay Eighth Prince, let's not make a sound, let's just watch silently from the side, is that okay?" Cheng Yaojin said.

Yuchi Jingde said: "Yes, Eighth Prince, let's just watch and not speak!"

"That's the best!"

Li Chengfeng's medical skills are obvious to all.

First, he cured Li Yuanba's years of insanity, and then performed a craniotomy on Li Shimin, which subverted everyone's ideas. Later, he was sure to cure Jinyang Princess Li Mingda's incurable disease.

Therefore, even the imperial physician Duan He was ashamed of his medical skills. Everyone was very relieved of Li Chengfeng and believed that he would be able to save Qin Qiong.

Immediately afterwards, Li Chengfeng picked up a huge blood collection needle from the table, and said, "Qin Huaiyu, Qin Huaidao, you two, roll up your right sleeves. Next, I'm going to draw blood for you!"

"Okay Eighth Prince, you can take the blood of our two brothers!"

Qin Huaiyu said, from the tense expressions of the two, it seemed that they both had the attitude of seeing death as home.

Li Chengfeng smiled and said: "Don't be nervous, both of you! Although it is the first time for you to collect blood, as long as the blood collection does not exceed the range that the human body can bear, it will not have much impact on the two of you. It is a good thing for the two of you to promote the metabolism of your body!"

After finishing speaking, there was a bitter smile on the faces of the two brothers Qin Huaiyu.

Especially looking at the needle tube in Li Chengfeng's hand, it was big and thick.

There was a trace of fear in the expressions of the two of them.

Can this needle stick into the human body without pain? Take your own blood, and even say it is good for you?

But this is not to blame the two of them, because the two of them are not as advanced in thinking as Li Chengfeng, and they don't understand what science is.

Therefore, it is inevitable that you will feel scared when taking blood for the first time.

But in order to save Qin Qiong, even if they died, they were willing.

After all, Qin Qiong is their father, and Qin Qiong gave their lives.

It has to be said that the filial piety of the ancient people was absolutely super powerful. Allusions such as cutting meat to taste the mother, lying on ice and begging carp, all express a word of filial piety.

So Qin Huaiyu and Qin Huaidao, even if they died, they were willing to save Qin Qiong.

…

"You two, who will come first?" Li Chengfeng flicked the needle in his hand and looked at the two of them.

The two swallowed a mouthful of saliva at the same time, showing a look of fear.

In the end, it was Qin Huaiyu who spoke first and said, "I'm the elder brother, so let me come first!"

"No, brother, let me come first. If there is any good or bad, it will be my younger brother who has an accident first!" Qin Huaidao said suddenly.

Li Chengfeng pursed his lips, and said: "Stop arguing, you two, anyway, you two will come sooner or later! Besides, Qin Huaidao, do you not believe in my prince's medical skills? If there is any problem, you should come first Something? Bah, talking nonsense!"

"Since Qin Huaiyu is the elder brother, then elder brother will come first! I will first draw blood from both of your bodies, about a catty each, and then wait for you to recover some vitality before drawing again!"

"Okay, then I'll come from Xi'an, I'm my brother!"

Qin Huaiyu said.

He pursed his lips, trembling a little.

Li Chengfeng took a deep breath, patted Qin Huaiyu's right hand, and said, "Don't be nervous, nothing will happen!"

"Well, I believe in the Eighth Prince's medical skills!"

Qin Huaiyu said firmly, with a light of faith in his eyes.

Meanwhile, the ministers on the side poked their heads and looked towards the middle of the living room. They all wanted to see how Li Chengfeng took blood?

Is it cutting the pulse? Or cut meat?

However, when Li Chengfeng took out a big and thick needle, everyone was scared, even Li Shimin himself was no exception.

Such a large needle, inserted into the human body to collect blood? Then you have to stab someone to death? If it is not stabbed to death, it will also hurt to death, right?

Li Shimin wanted to ask Li Chengfeng, is it useful?

But after thinking about it, he decided to forget it.

Because Li Chengfeng said before, none of you are allowed to speak, otherwise you will interrupt your treatment process, and whoever quarrels with Qin Qiong will be responsible.

Thinking of this, Li Shimin still closed his mouth obediently.

After all, he didn't want to be charged with this crime, and he also wanted Li Chengfeng to be able to pull Qin Qiong back from the gate of hell!

…

Immediately afterwards, Li Chengfeng tied Qin Huaiyu's upper arm with a rubber band.

He patted Qin Huaiyu's arm lightly so that the location of the blood vessels could be revealed.

Sure enough, the blood vessels on Qin Huaiyu's arm swelled up very quickly.

Li Chengfeng looked at Qin Huaiyu and said, "Next, I will use this needle to insert into your blood vessel to extract blood. It won't hurt very much! But if you faint from blood, you can close your eyes!"

"It's okay, Eighth Prince~lightnovelpub.net~ Just come, I'm not afraid!" Qin Huaiyu said firmly.

"Okay, then I'll start!"

After all, Li Chengfeng used very professional movements to insert the needle tube into the blood vessel of Qin Huaiyu's arm, and then pulled slightly to extract the blood.

Everyone saw that the dark red blood in the needle tube was accumulating and piling up. It was all the blood extracted from Qin Huaiyu's arm.

Cheng Yaojin and the others felt that this was nothing because they had gone to the battlefield to kill the enemy.

Some ministers covered their eyes, and their expressions looked very painful. Some of them even turned pale and their lips trembled.

Because the picture of blood drawing looks really scary.

Li Shimin stood aside, didn't speak, just watched quietly.

Soon, Li Chengfeng drew a needle of blood out, then pulled out the needle, and poured all the blood into another glass bottle.

Then continue to draw blood.

This needle tube is a large needle tube of 250 ml, and the capacity of the glass bottle is 500 ml.

Li Chengfeng changed Qin Huaiyu's other arm to draw blood.

A total of two needles were drawn, a total of 500 ml, about a catty of blood.

Li Chengfeng put all the drawn blood into glass bottles.

Afterwards, Li Chengfeng used a cotton swab dipped in alcohol to disinfect Qin Huaiyu's arm.

Seeing Qin Huaiyu's pale face and trembling lips, Li Chengfeng smiled and said, "Okay, you can go down and rest, Qin Huaiyu!"

"This, is this all right?"

"Ding, surprise from Qin Huaiyu, naughty is worth 199!"

Li Chengfeng nodded his head and said: "Of course, otherwise, do you think that to get blood, you have to cut your arm with a knife, and then let your blood flow straight away?"
