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

"Well...but, it doesn't matter. You just don't have to be born anyway!"

"Okay Eighth Prince, let's not speak out, let's just watch silently from the side. Is it OK?" Cheng Yaojin said.

Yuchi Jingde said, "Yes, the Eighth Prince, let's just watch and don't speak!"

"That's the best!"

Everyone can see Li Chengfeng's medical skills.

First, he cured Li Yuanba's madness for many years, and later he performed a craniotomy on Li Shimin that subverted everyone's concepts. Later, he was sure to cure the incurable disease of Jinyang Princess Li Mingda.

Therefore, even the imperial physician Duan He felt inferior to his medical skills. Everyone was relieved of Li Chengfeng and believed that he could definitely save Qin Qiong.

Immediately afterwards, Li Chengfeng picked up a huge blood-collection syringe from the table and said, "Qin Huaiyu, Qin Huai said, you two roll up your right sleeves, and next, I will draw blood for you!"

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

Qin Huaiyu said, from the nervous expressions of the two, they seemed to be in a state of silence.

Li Chengfeng smiled and said, "Don't be nervous either! Although it is your first time to collect blood, as long as the blood collection does not exceed the range of the human body's tolerance, it will not have much impact on you two. In addition, it can

Promoting your body's metabolism is a good thing for you both!"

After saying that, a bitter smile appeared on the faces of the two brothers Qin Huaiyu.

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

The two of them had a hint of fear in their expressions.

Can this needle be inserted into the human body without pain? Taking your own essence and blood even said it is good for you?

But it’s not their fault, because their thoughts are not as advanced as Li Chengfeng and they don’t understand what science is.

So it is inevitable that you will feel scared for the first time you collect blood.

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

After all, Qin Qiong is their father, and the lives of the two were also given by Qin Qiong.

I have to say that the filial piety of ancient people was definitely super powerful. The allusions of cutting flesh and smelling mothers, lying on ice to seek carp, all express the word filial piety.

Therefore, even if Qin Huaiyu and Qin Huaidao died, they were willing to save Qin Qiong and the others.

...

"Who will come first for you two?" Li Chengfeng blasted the needle in his hand and looked at the two of them.

The two of them swallowed a saliva at the same time, revealing a look of fear.

In the end, Qin Huaiyu spoke first and said, "I am my brother, so I'll do it first!"

"No, brother, I'd better do it first. If there is one, then it's my brother that I'll have something to do first!" Qin Huaidao said suddenly.

Li Chengfeng pursed his lips and said, "Don't argue with you two, you two will come sooner or later! Besides, Qin Huai said, "Don't you believe in this prince's medical skills? You should come first if you have anything to do.

What’s the matter? Bah, talk nonsense!”

"Since Qin Huaiyu is the elder brother, then let me do it first! I will extract the blood from your two bodies, about one pound each, and then wait until you recover some vitality before extracting it!"

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

Qin Huaiyu said.

He pursed his lips and shivered.

Li Chengfeng took a deep breath, patted Qin Huaiyu's right hand, and said, "Don't be nervous, there will be no problem!"

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

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

The ministers on the side looked into the middle of the living room. They all wanted to see how Li Chengfeng collected blood?

Is it a vein cut? Or is it a vein cut?

However, when Li Chengfeng took out a large and thick needle, everyone was scared to the point of tightening, and even Li Shimin himself was not included.

Such a large needle tube is inserted into the human body to collect blood? Then you can't stab someone to death? If you don't stab him to death, it will hurt to death, right?

Li Shimin wanted to ask Li Chengfeng if this is useful?

But he thought about it and then let it go.

Because Li Chengfeng said before, no one of you is allowed to speak, otherwise it will disturb your own treatment process. If Qin Qiong dies, you will be responsible for the refusal.

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

After all, he didn't want to bear this crime. He also wanted Li Chengfeng to pull Qin Qiong back from the gates of hell!

...

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

He gently patted Qin Huaiyu's arm so that the position of the blood vessels would appear.

Sure enough, the blood vessels on Qin Huaiyu's arm soon bulged.

Li Chengfeng looked at Qin Huaiyu and said, "Immediately, I want to use this syringe to insert it into your blood vessels and extract blood. It won't hurt! But if you dizzy, you can close your eyes!"

"It's okay, the eighth prince, come just because I'm not afraid!" Qin Huaiyu said strongly.

"Okay, then I'll start!"

After saying that, Li Chengfeng used a very professional movement to insert the syringe into Qin Huaiyu's arm blood vessels, and then pulled it slightly to extract the blood.

Everyone saw that the dark red blood in the syringe tube was accumulating and stacking, all of which were extracted from Qin Huaiyu's arm.

Cheng Yaojin and others thought this was nothing because they had been on the battlefield to kill the enemy.

Some ministers covered their eyes, their expressions seemed very painful, and some of them even turned pale and their lips shivered.

Because this blood-drawing scene looks really scary.

Li Shimin stood aside, without saying a word, just watching quietly.

Soon, Li Chengfeng took out a needle and then pulled out the needle, putting all the blood into another glass bottle.

Continue to draw blood.

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

Li Chengfeng replaced Qin Huaiyu with another arm and drew blood.

A total of two syringes were drawn, totaling 500 ml, about one pound of blood.

Li Chengfeng put all the blood drawn out in a glass bottle.

Afterwards, Li Chengfeng used a cotton swab to dip alcohol to disinfect Qin Huaiyu's arms.

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

"Is that okay?"

"Ding, the surprise from Qin Huaiyu, naughty value is 199!"
