Liu Chengfeng was very unhappy. He was a famous land trace identification expert in Shirakawa City. Xu Yuntian actually said that he had some omissions, which made him very embarrassed.

"Liu Chengfeng, Xu Yuntian's ability is not something you can imagine. He is definitely at the top expert level in your trace identification. Just ask for advice humbly!" Mo Wenxuan glared at Liu Chengfeng.

"Yes! Unless Xu Yuntian can say that the scene was missed, and I will only convince him by solving the case with this omission!" Liu Chengfeng said unconvincedly.

Mo Wenxuan looked at Xu Yuntian and said, "Xu Yuntian, just say you missed the scene. This case must be solved, otherwise the murderer will continue to kill people."

Xu Yuntian nodded and said, "Okay."

Then he looked at Liu Chengfeng and said, "Actually, your on-site identification is pretty good, but you have overlooked a very important thing, the gravity of this shoe print!"

"The gravity of the feet? What does it mean?" Liu Chengfeng said inexplicably.

"This murderer is wearing 43 size shoes. You can infer that the murderer is about eight in height and weighs about one hundred and eight in weight. This is correct, but the murderer is very cunning. He deliberately wears large-size shoes to commit the crime."

"In fact, his feet are only thirty-nine in size, and he is wearing large-sized shoes to commit crimes. The shoe prints left behind are deliberately confusing your judgment." Xu Yuntiandao.

Liu Chengfeng frowned and said, "Xu Yuntian, why are you sure the murderer's feet are only thirty-nine yards?"

"This is back to the gravity problem of footprints I just mentioned. For size 39 feet, wearing size 43 shoes, the shoes are obviously bigger. Although the shoe prints on the ground are size 43, the shoe prints generated by gravity on the soles of the feet will have a slight and heavy weight."

"That is to say, the shoe prints on the shoes are clear in the middle and the side is light, which is the footprints left by small feet and large shoes. Therefore, the murderer is actually only 1.65 meters tall and weighs about 120 kilograms." Xu Yuntian explained.

Liu Chengfeng squatted down and looked at the shoe prints carefully. As expected, it was like Xu Yuntian's analysis. He grabbed his scalp and nodded in shame and said, "Your analysis is correct. I ignored the problem of this shoe print."

"Oh! We have indeed made a mistake in checking the murderer's direction. We actually positioned a man of 1.8 meters!" Mo Wenxuan frowned.

"Liu Chengfeng, do you get any information from the wound on the deceased's neck?" Xu Yuntian looked at Liu Chengfeng.

"The deceased's neck wound was neat, and the trachea and aorta were cut off with one knife, which shows that the knife was sharp. The murderer was a veteran and thought he might have worked as a doctor, butcher and other profession..." Liu Chengfeng said.

Xu Yuntian nodded and said, "The problems you mentioned are very common problems. Most people can see that you still haven't seen the hidden problems in the knife edge."

Liu Chengfeng showed a hint of surprise and said, "What! There is still a hidden problem in the knife edge. What is the problem?"

"Have you looked at the blade carefully? Although the blade is very uniform, the force has been applied to the muscles and has undergone subtle changes. Look here!" Xu Yuntian pointed at the blade of the deceased's neck and said.

Liu Chengfeng approached and looked closely. He found that the blade edge was a bit deviated and said inexplicably: "The blade edge was a bit deviated. This is a change in the muscles of the knife, which is very normal!"

"If you think the knife edge is normal, then you are wrong! The knife edge is very thin, like a line, which means that the murderer's knife is very thin. If it is offset on the muscle, it means that the murderer's hand is not holding the knife firmly."

"What is the reason for not being able to hold it firmly? That is, the murderer lacks one finger, and it should be that the middle finger is broken." Xu Yuntian analyzed.

Liu Chengfeng frowned and said, "The murderer broke his middle finger, isn't this possible?"

"It's absolutely impossible, and I infer that the murderer broke his middle finger for about half a year, so it's not difficult to find the murderer. Just go to the hospital to search for the man who broke his middle finger within half a year, and the age of fifty years old..." Xu Yuntiandao.

Mo Wenxuan showed joy and said, "Oh! I will send someone to the hospital to investigate the person who cut his middle finger."

Mo Wenxuan immediately took out his cell phone and called, sent someone to the hospital to investigate the man whose middle finger had broken within half a year. Then he said to Xu Yuntian: "Yuntian, you have helped me so much, I'll treat you to a midnight snack."

Xu Yuntian nodded and said, "Okay, I'm really a little hungry."

He followed Qin Youcai and You Aimi along the way, traveling around for more than 60 kilometers, consuming a lot of energy, and felt a little hungry.

Mo Wenxuan took Xu Yuntian to a steak on the street. Mo Wenxuan ordered skewers and beer. Xu Yuntian and Mo Wenxuan ate skewers and beer on the street.

The two of them talked and chatted, talking about this perverted murder case. The pervert made four murders and killed six people. The youngest was only eight years old.

The methods were extremely cruel. In addition to ruining the dead, they also cut off the things on the dead. The worst deceased was killed more than fifty times, and many parts of the body were cut off.

The eight-year-old girl was even more miserable. Not only was she ruined, but her ears were cut off and parts of her body were cut off. It was a terrible sight.

After listening to Mo Wenxuan's story, Xu Yuntian said with anger: "After this scum catches him, he can't be killed so cheaply. He must torture this scum!"

"I want to torture this scum, but we have discipline and cannot abuse this scum." Mo Wenxuan shook her head and said.

"I have a way to abuse this scum, and you won't violate discipline." Xu Yuntian looked at Mo Wenxuan and said with a smile.

"Oh! What's the solution?" Mo Wenxuan said with interest.

"After finding the address of the scumbag, we will catch people together. After we catch him, I will tamper with him, making him worse than death..." Xu Yuntian said.

Mo Wenxuan nodded and said, "Okay, your method is good."

As soon as she finished speaking, a voice came from the walkie-talkie: "Mo Wenxuan, I found the person who broke the middle finger. His name is Zeng Xinhuai, who is 1.65 meters tall and weighs 125..."

"Oh! Zeng Xinhuai is the murderer, let's catch people right away!" Mo Wenxuan stood up hurriedly.

Mo Wenxuan was driving a motorcycle, Xu Yuntian sat behind her, and Xu Yuntian held her waist.

Mo Wenxuan's cheeks were slightly red. She took Xu Yuntian toward Zeng Xinhuai's home. About ten minutes later, the motorcycle stopped at the entrance of Nanhe Community.

"Zeng Xinhuai's family lives on the 18th floor and Room 7th in this community. He should be at home now. The lights are on in the room and he has not yet gone to bed." Mo Wenxuan pointed at Xu Yuntiandao.

"You guys just stay at the door and I'll catch people." Xu Yuntian said to Mo Wenxuan.

"If you take action against this scum, I will use your actions. It's enough for my people to go." Mo Wenxuan said disdainfully.

"Mo Wenxuan, don't be careless. This guy should be a warrior. Maybe he has reached Huajin. You may not be able to catch him." Xu Yuntian frowned.

"Is this scum so powerful?" Mo Wenxuan said in disbelief.

"Believe me, judging from his killing methods, this guy is definitely a warrior." Xu Yuntian analyzed.
