Zhou Heng nodded, motioned to Zhang Ankang to get some charcoal powder, spread the burden on the outside of the knife on the bed, and asked Luo Zongqi to pinch the position of the blade, Zhou Heng held the paper containing the charcoal powder and shook it gently, and the entire handle was evenly sprinkled with charcoal powder.

Zhou Heng was extremely nervous, this knife grabbed Xiao Liuzi with gloves during the operation, and he didn't know if he would wipe all the fingerprints off.

Taking a deep breath and brushing it lightly, the excess toner fell one after another, leaving seven or eight black marks on the handle.

Zhou Heng held a magnifying glass and looked at it carefully, the fingerprints and palm prints were all there, very clear, and if you distinguish them carefully, the directionality of the grip is very obvious.

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

"Are you sure no one has ever grabbed the handle of this knife again?"

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

"No, I saw him fall to the ground, so I rushed over, wrapped the knife around with a sweat towel, when a kid was about to grab the knife and pull it out, I kicked him aside, let the barracks doctor invite, and then I came directly to the Huichun Hall by car, and no one 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 trembled, looked at the window, and the water droplets on the whole paper were quite even, so he padd the rice paper and held it firmly on the handle of the knife.

The eyes of everyone in the room were staring at Zhou Heng's movements, and he held down the handle of the knife for a moment, then he easily opened it, pulled the corner of the rice paper, and ripped it off.

Spread out on another hospital bed again, a few heads came over, and a clear palm print appeared on the paper, not only the fingerprints of the fingers, but also the palm prints were also very clear, and Zhu Yunmo's eyes lit up when he saw this.

"Zhou Heng really has yours, so we just need to compare the palm prints of those two, right?"

Zhou Heng thought about it for a while, he was not as excited as Zhu Yunmo, and the person who committed the murder directly was not necessarily the person behind the scenes, he could use the entire school competition to arrange all this, this person was absolutely thoughtful.

But he didn't say it, one is that this is just his own speculation, and the other is that Luo Zongqi doesn't know who it is, it is better for Wei Guogong to come forward to be more convincing in this matter, but let Zhu Yunmo go to Wei Guogong, he will never go.

Zhou Heng pursed his lips and said: "You can get the palm prints and fingerprints of those two people first, and then compare them, as for what to use for, I hope Luo Zongqi will not disclose them for the time being, so as not to startle the snake." ”

Luo Zongqi nodded, and hurriedly clasped his fists and saluted.

"Shizi and Dr. Zhou rest assured, it will not be leaked at this time, I will go back to take the fingerprints and palm prints of those two, and send someone to take care of them, if it is really a mistake, it is better to say, I am afraid that someone with a heart wants to do evil."

After speaking, he got up and said goodbye, and did not stay any longer, and did not take the knife away, Zhou Heng's eyes fell on the knife, and he raised his eyes to look at Zhu Yunmo.

"This knife, it's best to send it to the Weiguo Mansion, after all, this matter is aimed at the grandson of the Weiguo Gong, Huichun Hall should not be involved, this place has not yet opened, if you make enemies now, I am afraid that it will affect the future business."

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

"Why don't you send my little servant back later?"

Zhu Yunmo waved his hand, "It's not proper, if someone really targets you and the Weiguo Mansion and asks a little guy to go back with the knife in his arms, do you want everyone to know that the traces on the knife were found by the Rejuvenation Hall?" ”

Yang Weijun was stunned, and instantly coaxed, sighing and not knowing what to do.

Zhou Heng thought for a while, "Why don't you ask Wei Guogong to come over, and say how about discussing the follow-up treatment?" ”

Zhu Yunmo nodded, "It's feasible, you can send someone to go, so it's not conspicuous, I'll go to Beishan to see the progress of the project, and we'll 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 Wei Guogong, and it seemed that he had to come forward himself.

"Okay, then I'll let Qu Ziping and Brother Xue run, Qu Ziping's ability to adapt to changes is strong, and Brother Xue can also support the façade."

......

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

Zhou Heng hurriedly got up and waved his hand at everyone, these people all retreated, and then Shi Li said:

"Wei Guogong, please take a seat."

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

"What are you asking the old man in a hurry? 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 hurt Yang Gongzi, Luo Zongqi locked up the two people who hurt people, don't touch the handle of this knife, there are palm prints and fingerprints of the injured person on it, this is the fingerprint traces of rubbing, I asked Luo Zongqi to take the palm prints and fingerprints of the two people, if you compare, you can know who hurt Yang Gongzi."

Yang Guangchen looked at the knife, and then looked at the paper with the rubbing palm print handed over by Zhou Heng, and then looked at his hand, compared with the palm print on the paper, it seemed that his palm was more slender than the person, Yang Guangchen's eyes widened, and he seemed to understand what he was trying to do.

"You're saying that everyone's palm print is different, so as long as you determine who this palm print is, that person is the perpetrator?"

Zhou Heng nodded, "The court trial case, in the end, they have to sign and draw the charge, all they keep is the fingerprint of a finger, we use the palm print and all the fingerprints to compare together, this is more accurate, and it can also convince the public." ”

Yang Guangchen put away his initial indifference, squinted 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 that that is why you came to the old man?"

Zhou Heng nodded, "My son and I have just returned to Beijing, and we are not familiar with everything here, such a method is definitely not coming towards us, but Yang Gongzi is different, he is the only male in the third generation of the Weiguo Mansion, if there is a mistake, I am afraid that the Weiguo Mansion will really have no successor." ”

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

"In your heart, I must have thought that I was pulling the prince to do business in the front, so I didn't do my job, and the back foot of the Weiguo Mansion owed me a life-saving grace, and at this moment I came up with these doubts, it must be easy for you to think more.

To say a big disrespectful word, before I came to the capital, I didn't know who you were Wei Guogong, and you had nothing to do with me, just because Xiao Bo said that Lord Zhang Fuling was good friends with you and was taken care of by you.

Master Zhang is thousands of miles away, entrusting Zhang Wanxun's life to me, this trust makes me look at Lord Zhang with admiration, so I also have a little more respect for Wei Guogong, otherwise I will not help Yang Gongzi deliver the news today, I think his little maid out of the door of the Rejuvenation Hall, before he arrived at the Wei Guo Mansion, it is estimated that he will encounter an accident. ”

Zhou Heng's words were very unkind, and they could even be said to be extremely excessive.

However, Yang Guangchen was not angry, he looked at Zhou Heng twice, obviously it was this Doctor Zhou who asked him to come back to the Spring Hall, his last sentence was very right, if the little guy next to Yang Weijun went out with a knife, it would be too attention-grabbing, and maybe he would be dead on the street immediately.

And when he came here, ordinary people wouldn't think much about it, after all, he broke up here last time, and talked about Yang Weijun's injury with Huichun Hall, and also said that in the past, this idea was really thoughtful, and Yang Guangchen had to admire it.

"The old man heard Zhang Shaoqing mention you, saying that you have excellent medical skills, a promise, and an honest person, it seems that what he said is right, the old man understands, the knife and rubbing the old man take it away, and the old man will go back to deal with the affairs of the five military camps, thank you."

Yang Guangchen got up, Zhou Heng had already rewrapped the knife, wrapped it in plain silk cloth, put it in a box of calligraphy and painting scrolls, 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 was cautious, until the door, Yang Guangchen's entourage followed, he paused and waved his hand at Zhou Heng.

"Doctor Zhou, please go back, thank you for saving Jun'er this time, and there will be a lot of thanks in the future!"

Zhou Heng knew what this Wei Guogong meant by saying this outside the door, so he hurriedly bowed down and saluted.

"Congratulations to Wei Guogong, after Yang Gongzi recovers from his illness, our Huichun Hall will send a car to send Gongzi back, it is a car dedicated to transporting patients, and it is absolutely comfortable."

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

"Hold, let's go home!"
