After everything was ready, Chen Chen communicated with Zhao Zheng for a long time, and Zhao Zheng was almost crying because he couldn't help it.

"Since that's the case, we are ready to start." Chen Chen pointed at Zhao Zhengdao.

"Hurry up."

Chen Chen nodded, took the prepared disinfection cotton ball and started disinfecting. Then he took the syringe that had already drawn the hollydocaine and began to undergo anesthesia.

Zhao Zheng didn't say a word, and the old doctor said "ah".

Chen Chen looked at him unhappily, "Stop the sound!" and then continued his movements.

Zhao Zheng only felt a small needle entering the wound, which hurt a little, and then slowly, it seemed that something had penetrated into his skin. After a while, it didn't hurt there any more.

"It's so amazing. The place where you stabbed the needle will not hurt anymore." Zhao Zheng felt very strange because this feeling really existed on him.

"Stop the sound!" Chen Chen reiterated it again.

"Oh, sorry!" Zhao Zheng quickly closed his mouth with a smile on his face.

Chen Chen only has one box of lidocaine, and this box is available because he is preparing to practice using it when assessing the students. And a box of lidocaine is only 10 pieces.

Chen Chen prepared 3 pieces, but at this moment, Chen Chen only planned to use two pieces. After all, Zhao Zheng is still a child now, and it is not large in terms of area or size.

After two shots, Zhao Zheng could basically not feel the pain in the wounded area.

"I'm going to start the operation, Ah Sheng, if Zhao Zheng struggles, you have to hold him down." Chen Chen ordered, "Old sir, just help me."

The old doctor nodded. At this moment, he was already very curious about Chen Chen's medical skills.

Chen Chen quickly put on a disinfected plain clothes, put on a hat, mask, and sterile gloves. Of course, his hands had been washed before coming in.

Chen Chen knew that he must move quickly, otherwise Zhao Zheng would suffer once the medicine was effective.

He picked up the scalpel with his right hand, pressed Zhao Zheng's leg with his left hand, and cut the skin from the side. A hole, about 8 cm, just after he cut open the skin, Chen Chen saw the protruding broken bone surface, which penetrated through the muscles, accompanied by the blood stasis left before.

Zhao Zheng felt that the skin on his wounded part was cut open, but it didn't hurt at all. While he was curious, he really wanted to see what was going on.

At this moment, the old doctor also focused and was ready to listen to Chen Chen's instructions at any time.

"Gauze!" Chen Chen had no attraction device, so he could only use gauze to quickly suck the blood away. The moment he sucked away, the art field was extremely clear. Chen Chen had to find the bleeding point, otherwise, even if the broken bone was in the right position, it would be displaced due to the hematoma.

"Skin hook." Chen Chen's tools do not have special tools for orthopedics, only common in surgery, so everything is simple.

The old doctor listened to Chen Chen's voice, "Skin hook, skin hook, oh, this!" and then quickly handed it to Chen Chen.

Chen Chen used two skin hooks to pull open the wound's skin and said, "Take it."

The old doctor quickly took over without a teacher.

Chen Chen nodded with satisfaction and began to look for the bleeding point. However, he might not be able to find it. After all, before the operation, the injury had been relatively long and it might not be necessary for him to solidify himself.

After searching for a while, I found that there was not much bleeding, which means there was no major bleeding point, and it should have been the one who solidified himself. Chen Chen also felt relieved.

Next, we will deal with the broken bones.

Broken bones come out of the muscles, so to deal with broken bones, you need to break the muscles first. Chen Chen took two blood vessel clamps, clamped both ends of a muscle, and then used a scalpel to cut them out from near the broken bones.

...

When Chen Chen finally stitched his skin, almost two hours had passed, and his forehead was covered with sweat.

He himself broke his legs and even sat for this operation, not to mention that he only ate one bowl of porridge and an egg in the morning. After sewing the wound, Chen Chen sterilized the sterilization cotton ball, put gauze on it, and then glued tape. He picked up two small wooden boards prepared in advance and placed them on the front and back of Zhao Zheng's left calf. He asked the doctor to help him hold it for a little, then picked up the bandage and began to wrap it around.

When the bandage knot was finally tied, Chen Chen finally breathed a sigh of relief and looked at Zhao Zheng, "Okay. You have to recover at least 3 months. Within 3 months, your leg cannot touch the ground or exert force. You are still young, and you should recover faster, and there should be no sequelae in the future."

Zhao Zheng also relaxed himself. He had already felt the pain since Chen Chen stitched it, but he did not shout, and his face turned red at this moment.

Chen Chen also had to admire the child in front of him. If Chen Chen said that he was not Ying Zheng in the future, he would not believe it.

"Old sir, for the next conditioning, you will usually use more blood-activated drugs, so I'll trouble you."

"Mr. Chen, you are polite!" At this moment, the old doctor was completely impressed. He was just a child, but he actually completed such a creation move. Yes, in his opinion, Chen Chen was as mysterious as the genius doctor Bian Que at this moment. "Mr. Chen, I have a question below, if this method is used, can Bian Que's heart-changing technique be performed?"

Chen Chen looked at him and was quite surprised. He did not expect that this doctor was not a ignorant person. "Under the current conditions, it is difficult, and perhaps, it will not be able to achieve the means of the ancestors for hundreds of years."

"Master?" The old doctor's eyes widened, "Could it be..."

"It's not to be said." Chen Chen said lightly, "It's not to be said." It's a pity to go back to the Warring States Period and not borrow Bian Que's name. Moreover, Chen Chen must also explain his origin. Otherwise, he will be a refugee.

Asheng's eyes lit up when he looked around. It turned out that his younger brother was the descendant of Bian Que. No wonder he was in the mountains. No wonder he had such a magical medical technique!

Zhao Zheng was most grateful in his heart. If it weren't for Chen Chen, he might have been disabled in the second half of his life! For anyone, this would be unbearable.

"Sir, stay!" Zhao Zheng quickly spoke out when he saw Chen Chen leaving. At this time, he no longer regarded Chen Chen as a child.

Chen Chen's face was full of dark lines. Mr.? Is he that old? Of course, he also knew that this was just a respectful title for the other party by people in this era, "What's the matter?"

"Zhao Zheng thanks Mr. Zhao for his compassionate help! Zheng will definitely give him a good reward!"

Chen Chen rolled his eyes, "The medical expenses and surgical medicines cost are thirty gold in total." Chen Chen did not want to blackmail Zhao Zheng, but that he had only one of these medicines, and he had nothing after using them.

Zhao Zheng didn't think the money was expensive at all, and even the old doctor thought it was not expensive, and Asheng thought it was not expensive, so Chen Chen thought it was not expensive himself.
