Zhou Heng nodded and signaled Zhang Ankang to get some charcoal powder. He spread the bag outside the knife on the bed, and let Mr. Luo pinch the blade. Zhou Heng held the paper containing charcoal powder and shook it gently, and sprinkled charcoal powder evenly on the entire handle.

Zhou Heng was extremely nervous. During the operation, Xiao Liuzi and the others grabbed the knife with gloves. I wonder if they would wipe off all their fingerprints.

Take a deep breath and use a brush, and gently brush it, and the excess toner fell down, leaving seven or eight black marks on the handle.

Zhou Heng held up a magnifying glass and looked carefully. He had fingerprints and palm prints, which were very clear. After careful identification, the direction of the grasp was very obvious.

Zhou Heng raised his eyes and looked at Mr. Luo.

"Are you sure that no one has grabbed the hilt of this knife again?"

With this question, everyone looked at Mr. Luo. He didn't dare to speak. He thought about it carefully and then shook his head.

"No, when I saw him fall to the ground, I rushed over and wrapped his sweat towel around the knife. At that time, a kid wanted to grab the knife and pull it out. I kicked him aside and asked someone to invite the military officer. Then he went to Huichuntang directly by car, and no one had ever grabbed the knife again."

Zhou Heng nodded, grabbed a very thin piece of rice paper, and asked Zhang Ankang to spray some water on the paper. Zhou Heng shook and looked at the window. The water droplets on the entire paper were quite even, so he pressed the rice paper hard on the hilt.

Everyone in the room stared at Zhou Heng's movements. He held the handle of the knife for a moment before he could easily open it, pulling a corner of the rice paper and pulling it off.

It spread flat on another hospital bed again, and several heads came over. A clear palm print appeared on the paper. Not only the fingerprints of the fingers, but also the palm prints were very clear. Zhu Yunmo's eyes lit up when he saw this.

"Zhou Heng really has you, so we just need to compare the palm lines of those two people, right?"

Zhou Heng thought about it for a moment. The person who was not as excited as Zhu Yunmo, who directly committed the crime was not necessarily the person behind the scenes. He could use the entire school competition to arrange all this. This person was absolutely meticulous.

However, he didn't say it out loud. One is that this is just his own guess. Besides, Mr. Luo didn't know who he was. It would be better for Duke Wei to come forward and make it more convincing. But if Zhu Yunmo went to find Duke Wei, he would never go.

Zhou Heng pursed his lips and said, "You can get the palm prints and fingerprints of the two of them first, and then compare them. As for what they are used for, I hope Mr. Luo will not disclose it for the time being, so as not to alarm the snake."

Mr. Luo nodded and quickly hugged his fists and saluted.

"Don't worry, the prince and Doctor Zhou, that there will be no leak at this time. I will go back and get the fingerprints and palm prints of the two of them, and send someone to take care of them. If it is really hurt by accident, it's okay, but I'm afraid that those who are interested want to do evil."

After saying that, he stood up and said goodbye, and did not stop anymore. He did not take the knife away. Zhou Heng's eyes fell on the knife and looked up at Zhu Yunmo.

"It is best to send this knife to the Duke of Wei's Mansion. After all, this matter is targeted at the grandson of Duke of Wei's Mansion. Huichuntang should not be involved. It has not opened yet. If you make enemies now, I am afraid that it will affect your future business."

Yang Weijun looked at Zhu Yunmo timidly. He knew that Zhu Yunmo would not go, after all, the relationship has not eased yet.

"Why do I need my servant to send him back in a while?"

Zhu Yunmo waved his hand, "No, if someone really targets you and Duke Wei's Mansion and asks a servant to go back with the knife brightly, do you want everyone to know that the traces on the knife were found by Huichuntang?"

Yang Weijun was stunned and instantly became timid, sighing and didn't know what to do.

Zhou Heng thought for a while, "Why do you want someone to invite Duke Wei to come here? Let's discuss the subsequent treatment?"

Zhu Yunmo nodded, "It's feasible, you can send someone there. This is not conspicuous. I'll go to Beishan to see the progress of the project. We will discuss the opening time in the evening. I see that there seem to be more and more patients downstairs."

Zhou Heng knew that he wanted to avoid Duke Wei, and it seemed that he had to come forward by himself.

"Okay, then I'll let Qu Ziping and Brother Xue go for a trip. Qu Ziping has strong adaptability and Brother Xue can support the store."

Half an hour later, Zhou Heng and Desheng had just finished talking about opening the business, and the door was pushed open instantly. Duke Wei stepped in, followed by Qu Ziping and Boss Xue.

Zhou Heng quickly stood up and waved to everyone. All of them retreated, then bowed and said:

"Duke of Wei, please sit down."

Yang Guangchen sat on the chair opposite Zhou Heng and glanced up and down.

"What's the matter when you rush to ask me for help? But Jun'er has some physical problems?"

Zhou Heng shook his head, opened the cabinet and took out the knife.

"This is the knife that hurts Mr. Yang. Mr. Luo locked up the two injured people. The handle of the knife should not touch it. There are palm prints and fingerprints of the injured person. This is the fingerprint traces printed in the rubbing. I asked Mr. Luo to take the palm prints and fingerprints of the two. If you compare, you can know who hurt Mr. Yang."

Yang Guangchen looked at the knife, then looked at the paper with palm prints handed over by Zhou Heng, and then looked at his hand. Compared with the palm prints on the paper, his palm seemed to be longer than the man's. Yang Guangchen widened his eyes, as if he understood what he was going to do.

"You mean, everyone's palm lines are different, so as long as you determine who this palm lines are, then the person is the perpetrator?"

Zhou Heng nodded, "In the end, we have to sign and seal the case in the lobby. All they have to keep is a fingerprint of a finger. We compare the palm prints with all fingerprints together. This is more accurate and can convince the public."

Yang Guangchen put away his initial indifference, squinted his eyes and looked at Zhou Heng, and paced back and forth in the room.

Finally, his eyes fell on the knife and asked tentatively:

"What did you think of, so I came to me?"

Zhou Heng nodded, "The prince and I have just returned to Beijing and are not familiar with everything here. Such a method must not be directed towards us, but Mr. Yang is different. He is the only male member of the third generation of Duke of Wei's Mansion. If there is a mistake, I am afraid that the Duke of Wei's Mansion will really have no successor."

Yang Guangchen looked at Zhou Heng cautiously, and Zhou Heng smiled slightly. The old man was quite cautious and said slowly with a sigh.

"In your heart, I must have thought that I was holding the prince to do business in front of me, and I was so unemployed, and the Duke of Wei's mansion owed me my life-saving grace. At this moment, I came up with these doubts, which will definitely make you think more.

Let me say a very disrespectful thing. Before coming to the capital, I didn’t know who you, Duke Wei, was. You had nothing to do with me, because Xiao Bo said that Lord Zhang Fuling had a good relationship with you and was taken care of by you.

Mr. Zhang was thousands of miles away and entrusted Zhang Wanxun's life to me. This trust made me look at Mr. Zhang with admiration, so I also had a little respect for Duke Wei. Otherwise, I would not have helped Master Yang to convey the message today. I think his servant would have encountered an unexpected situation before he arrived at Duke Wei's mansion."

Zhou Heng said this very impolitely, and it can even be said to be extremely transcendent.

However, Yang Guangchen was not angry. Instead, he looked at Zhou Heng for a few more times. Obviously, this doctor Zhou was invited to come back and forth to Chuntang. His last sentence was very correct. If the servant next to Yang Weijun went out with a knife, it would be too noticeable, and maybe he would be on the street immediately.

Most people don’t think much about him when he comes here. After all, the last time he ended up here, he was dissatisfied. He talked about Yang Weijun’s injuries with Huichuntang, and it was just a matter of time. This idea is really meticulous, and Yang Guangchen has to admire him.

"I heard Zhang Shaoqing mention you, saying that you have extraordinary medical skills and a promise of a thousand yuan. You are an honest person. It seems that he is right. I understand what I meant. Dao and Tuoyin took away, and I went back to deal with the matters of the fifth military camp. Thank you."

Yang Guangchen stood up, Zhou Heng had already wrapped the knife again, wrapped it in a plain silk cloth, placed it in a box of a scroll of calligraphy and painting, and handed it to Yang Guangchen with both hands.

He looked at Zhou Heng and walked out of the room with the scroll. Zhou Heng followed behind, bowing slightly, as if he seemed cautious. Until Yang Guangchen's entourage followed at the door, he stopped and waved his hand at Zhou Heng.

"Doctor Zhou, please come back. Thank you for your treatment this time. I will definitely thank you very much in the future!"

Zhou Heng knew that the Duke of Wei was talking about what this meant outside the door, so he quickly bowed and bowed.

"I respectfully send you the Duke of Wei. After Mr. Yang recovers from illness, we will send a car to take the young master back. It is a car specially used to transport patients, which is absolutely comfortable."

Yang Guangchen nodded and threw the box in his hand to the follower.
