It took more than an hour for Xu Junhao to finish the autopsy, and Jiayi stood there for more than an hour.

He, who was used to standing around the autopsy table for several hours, felt tired. He turned to look at Jiayi, and the young female police officer was still holding a notebook and taking notes.

After putting away the knife, he asked his assistant to be responsible for closing the abdomen. He took off his gloves and walked to Jiayi's side. He bumped her shoulder with his shoulder. When she looked up in confusion, he whispered:

"Let's go to my office and sit down. Take a break, drink some tea, and talk about the new gains."

"OK, sir." Jiayi nodded, took a long breath, closed the notebook, put away the pen, and followed Xu Junhao out of the autopsy room.

Another assistant who was responsible for taking notes also walked out and entered Xu Junhao's office together.

Sir Xu took off his hat and mask, and pulled off his hair tie to relax his long hair.

With his long hair loose and hanging slightly on the side of his face, Xu Junhao stretched his back before sitting behind his desk.

He picked up the tea tray and the thermos on the table, and measured the water temperature, selected the tea, and washed the tea in one go.

After pouring out the first cup of tea, he sniffed the tea leaves rinsed by the hot water, sighed with satisfaction, and then poured water again and made a shallow brew. After a few seconds, the fragrance of the tea spread all over his face, and he skillfully held the lidded bowl to pour tea for Jia Yi and his assistant.

"The ultimate goal of playing with tea is the lidded bowl. No matter what purple clay teapot or eight-piece set, it is not as comfortable and interesting to use as the lidded bowl." Xu Junhao poured tea for the two people, put down the lidded bowl, and stretched out his slender fingers that were very good at dissecting corpses, indicating that the two could taste the tea.

Jiayi picked up the small teacup and sniffed the tea. She felt that most of the depression in her chest had dissipated. She lowered her head and sipped it slowly. The fragrance of green tea filled her mouth and the hot

steam rushed into her nose. She swallowed the tea gently and felt the heat flowing through her body. Her mouth and nose were full of the tea fragrance. She felt clear-headed, relaxed and relaxed.

"How do you feel? My tea is good, right?" Xu Junhao raised his eyebrows proudly.

"It smells good. Thank you, Sir Xu." Jiayi put down the teacup and asked for another cup of hot tea. She drank three cups in a row before she relaxed her shoulders and sighed deeply.

"As long as you like it." Xu Junhao watched her whole body release from that tense and gnashing state, and then he raised the corners of his lips sincerely.

He took the notebook from his assistant, glanced at it for a few seconds, and then began typing on the computer.

A few minutes later, the printer on Jiayi's right hand side made a noise.

"This document records all the injuries on the body of the deceased Wang Xinqiu, including the fatal wound on his neck." Xu Junhao pointed to the document spit out by the printer and introduced:

"The various sizes and other information of all the injuries are also listed in it."

Jiayi stretched out her arm to pick up the three copies of the document, gave one to Xu Junhao and the forensic assistant, and then lowered her head to read it carefully.

A few minutes later, she frowned, picked up the red signature pen on Xu Junhao's desk, circled the stick diameter number calculated by Xu Junhao behind the stick wound, and circled the thin sword width data calculated based on the fatal wound below.

After staring at the two numbers for a while, she raised her head and pointed them to Xu Junhao.

"?" Xu Junhao looked at the two numbers he calculated, raised his eyebrows and looked over, asking what she meant.

"The diameter of the stick is greater than the width of the rapier, and judging from this size, this cane is thicker than an ordinary cane, and its thickness over the width of the rapier divided by one, the thickness is just right for a scabbard."

"You mean..." Xu Junhao's eyebrows pressed down and his eyes narrowed.

"Sir Xu, which do you think is longer, the stick or the rapier? Or can the existing data and information be used to infer their lengths?" Jiayi asked.

Xu Junhao shook his head. In order to calculate the length of the stick, he first had to know the murderer's exact height. Want to know the length of the rapier, there is also a missing necessary condition.

"However, they must be very long. It is very likely that the stick is longer than the rapier." Xu Junhao thought about it and nodded:

"From the large deviation in the cutting track of the wound, this rapier must be very long to make such a wide gap in one cut."

While talking, Xu Junhao opened his drawer and took out a long and thin scalpel and a short scalpel, and then took out a piece of eraser, and then used the two knives to cut the eraser respectively, and then pointed to Jiayi:

"You see, a long weapon will take longer to cut the eraser, and when people use force, the weapon will cut deeper.

"Furthermore, imagine that if these two scalpels are double-edged swords, when they cut inward, as long as the sword cuts deep enough and is completely buried in the flesh, the outward-facing blade will also leave cuts in the flesh.

"The marks left by these weapons in the flesh of the deceased can help us make judgments.

"The wooden stick is very long, and the scimitar is also very long."

"Then my guess becomes very likely." Jiayi sat up straight, leaned forward unconsciously, and raised her voice:

"I've seen that special weapon in a movie before. It's a long stick weapon that can be twisted and pulled, with a slender metal spear hidden in the middle.

"So, is it possible that the weapon used by the murderer is a cane with hidden secrets?"

"You mean there is a thin sword inserted in the cane?" Xu Junhao tilted his head slightly and pondered for a moment, then nodded and said, "It's not impossible. Many people in society will collect some rare weapons and treasures, such as placing swords and samurai swords in the most conspicuous places in the house for viewing, or hiding swords under pillows or beds... It seems reasonable that a big boss with status and position would carry a cane that is his most handy weapon."

Xu Junhao said, and suddenly laughed.

"?" Jiayi raised her eyebrows and wondered why Sir Xu suddenly laughed so brilliantly, but saw him suddenly open all his drawers and search through boxes and cabinets.

"Men probably all have a hobby of collecting handy weapons..." Xu Junhao rummaged for a long time before he found a signature pen under a notebook in the innermost drawer.

Jiayi looked at the signature pen with some confusion until he twisted the back of the signature pen twice and pulled out a half-finger-long knife. Then she understood what he meant.

"Just like this pen." Jiayi smiled.

"Yes, when I first found this pen, I wanted to sharpen it to be as sharp as a scalpel, so that I could clip it in my suit pocket and carry it with me. The police force can call me at any time, and I have to go at any time. With this pen, even if I am on a date or dinner, I can immediately have a knife to do preliminary autopsy at the crime scene." Xu Junhao shook the knife in his hand, "But later I found that it is generally better to avoid doing this kind of cutting and dissection on the spot, so it is not very useful. I just make it a small toy and throw it in the drawer."

"If it's something like this, the murderer can even carry such a weapon around in the city. There's no need to hide it deliberately. He can just carry it with him at all times." Jiayi said.

Xu Junhao nodded vigorously at Jiayi, thinking that her idea was great. He immediately started typing on the computer again, and entered her speculation into the report for reference.

A few minutes later, Jiayi took the report and let out a long breath.

Great, according to the data listed by Sir Xu, the murder weapon she saw was also stated. Although this murder weapon is still just a speculation, as long as there is this report, she can naturally ask all agents to pay attention to such a cane -

a cane that is thicker than an ordinary cane, has a mechanism inside, and can pull out a slingshot.

I wonder if Uncle Ye is smart enough to guess that the police can analyze so much information based on the wounds of the deceased, and even uncover the secret of his cane.

It's just a beating with a stick and a cutting with a stiletto. Maybe it's nothing special in Uncle Ye's eyes?

Don't people who are not forensic professionals think that the scars are no different from ordinary beatings with a stick and ordinary sharp cutting?

But the forensic doctor will magnify all the information on the corpse. What's more, Uncle Ye doesn't know that there is a person in the police force who witnessed the whole process of his crime.

She saw with her own eyes that he didn't use an ordinary stick, not even an ordinary wooden cane. She saw with her own eyes his whipping movements, and saw him pull out the stiletto and use this special weapon to kill people.

How could someone who saw it all with her own eyes ignore the marks left by the murderer on the victim's body as ordinary information?

She saw them all and wrote them down one by one in her notebook with marks that she could easily identify.

Jiayi turned herself into a slow-motion magnifying lens, infinitely slowing down the murderer's movements and infinitely magnifying everything about the murderer.

Holding several new reports that Xu Junhao had sent her in her hands, Jiayi still sat steadily in the guest chair in his office.

When Jiayi sorted the documents, she specially put one of them on the top. After reading the document again, she pointed it to Xu Junhao.

"Sir Xu, look at this diagram of bruises on the shoulder and neck of a corpse." Jiayi was pointing to the stick figure drawn by the forensic assistant.

"Huh?" Xu Junhao leaned over to look at the picture and raised his eyebrows in confusion.

"The wound on the right shoulder and neck of the deceased is very complete, and longer than the wound on the left shoulder." Jiayi poked her fingers on the left and right neck of the diagram.

She was guiding Xu Junhao, sending the information she saw and discovered in the flow image into Xu Junhao's mind.

"Yes, does this have a special meaning?" Xu Junhao frowned, still a little confused.

"Look at the difference in angles between the wound on the right shoulder and neck

of the deceased and the wound on the left shoulder and neck." Jiayi's voice was soft and persuasive. "Well... the wound on the right shoulder and neck is vertical, and the wound on the left shoulder and neck... has an angle tilted toward the inside of the front of the deceased..." Xu Junhao observed and slowly summarized.

A few minutes later, he suddenly raised his head, looked from the document to Jiayi, and said with surprise:

"Jiayi!"

"Yes, Sir Xu." Jiayi smiled softly at the way he stared at her.

Great, Sir Xu finally understood.
