Looking at Fang Jinyu's incredible expression, he must think that he and Long Moxun are very familiar with each other. However, this is not the case. The two of them really dislike each other.

"Um."

Fang Jinyu nodded and said, "You are right, we should speed up." Fang Jinyu breathed a sigh of relief. After listening to Luo Xuening's explanation, he looked visibly relieved and more energetic to handle the case.

Luo Xue Ning ignored Fang Jinyu's smug expression. She frowned and looked towards the broken railing. Suddenly, her eyes lit up and she found another key point.

"Dalbergia, this is Dalbergia, right?"

Luo Xuening opened her eyes wide, her round pupils showing a bit of the innocence of a young girl, and the happy expression on her face proved that she had found the key point. "Yes, this is yellow sandalwood, what's the difference?"

"Dalbergia wood, also known as yellow pear wood, is hard, has very fine pores, and contains a lot of resin. We can use this wood to analyze the basic situation of the murderer."

Fang Jinyu nodded. Rosewood looks good and is relatively sturdy. In Nanshao, most places use yellow pear wood to make furniture. He also noticed at the time that the railing was made of rosewood, but he did not think much about it. On the contrary, Luo Xuening found the key point through this small discovery. This made Fang Jinyu admire her, but also embarrassed himself.

However, Fang Jinyu did not show it on his face. He asked Xiang Luoxuening: "What did you find?"

"The murderer had to monitor the situation outside the tavern and cut the wood without making any noise within a quarter of an hour. This is enough to show that the murderer is good at using a knife.

He has thick ropes on his hands, a strong body, great strength, good martial arts, and strong night vision. Moreover, he knows everything about the restaurant. The murderer should be hidden among the restaurant staff, or perhaps a frequent guest. We can check the records of guests who dined in the Tianzihao room before the murder. "

"A little more."

Luo Xue Ning seemed to have seen through a piece of rosewood and opened the door to discovering the murderer: "The knife used by the murderer was brand new. Moreover, there will be glue on the rosewood. The knife used by the murderer to saw the wood must have some glue on it. Moreover, from the time the murderer prepared to commit the crime to the time the murder occurred, the murderer did not have the time to destroy the knife. We can check from the knife."

"Yes, I'll send someone to check. I'll look for records of knives being sharpened in iron shops in the capital these days. Maybe we can find some clues."

Although this was the first time the two of them had worked together, their level of compatibility was really comparable to that of people who had worked together for many years. This made Luo Xuening extremely excited. She had found the anti-drug solution again, just like the excitement she had felt when she was working on a case with her colleagues at the police station.

Soon, Fang Jinyu's men brought over a record, which was a detailed record of the people who came to the iron shop to cast knives in the past month.

Fang Jinyu looked through the record but didn't find anything special in it. Suddenly, his eyes fell on a name. He felt inexplicably that the name was extremely familiar.

Wang Ming, this is... Why did he seem to have heard of this person somewhere? But when he thought about it carefully, he couldn't remember clearly. Looking at the address Wang Ming left, Fang Jinyu also frowned. This was obviously a fake address. There was no such thing as Wulitun in Beijing. Could this be more perfunctory?

Because, casting knives is not something that can be completed in one go, especially when some customers have high requirements. Usually, customers will leave an address and come back to pick up the knives after they are made, or maybe the iron shop will simply deliver them to them. So, although leaving a fake address is a bit unexpected, it is not incomprehensible. After all, it is understandable that some people are more cautious.

However, Fang Jinyu still had to be more cautious. He was now supervising a murder case and could not be careless at all.

"Come here, check this man named Wang Ming and find out his address." Fang Jinyu had just finished giving the order when suddenly, a subordinate came to report: "Sir, a knife was found in the basement of the restaurant."

Upon hearing this, Fang Jinyu and Luo Xuening both frowned. They were just planning to start the investigation from the knife aspect, and then they found the knife.

"Take me there."

Fang Jinyu stood up, and Luo Xuening immediately raised her head from the pile of documents, stood up, followed Fang Jinyu out.

"Is this the knife?"

Luo Xuening looked at the knife in Fang Jinyu's hand that she had just dug out of the soil and asked, "Yes, there are traces of resin on it. It's just as you said."

"This knife was found by a few servants. It was buried under this tree. When the servants were cleaning the leaves, they accidentally swept out a bit of the knife handle. When they dug it out, they found it was a long knife."

"This guy is really weird. This kind of knife is obviously more suitable for fighting."

Fang Jinyu took the knife in his hand and played with it for a while, then said with regret, "Obviously, this is indeed a good knife, but it is being used in the wrong place."

"Perhaps, the murderer is used to using such knives, so the identity of the murderer..."

“It’s a soldier.”

Fang Jinyu and Luo Xuening said in unison, and their tacit understanding made Jing frown and make a "tsk" sound, expressing his disdain.

Fang Jinyu didn't care. He knew that the guard sent by Prince Jing was hostile to him, but what could he do? He was Prince Jing's man. What could he do to him? Of course, he ignored him.

"Master Fang, based on the evidence we have, I would like to make a profile of the murderer. This will make it easier for you to find the murderer."

Luo Xue Ning looked relaxed at this time. The more information they had, the more beneficial it would be for the progress of the case. This time, Luo Xue Ning could be sure to describe the appearance of the murderer.

"What's the prosody?"

Fang Jinyu frowned and looked at Luo Xuening in confusion.

"Well, criminal profiling is a commonly used investigative technique. It identifies criminals based on the analysis of crimes and criminal methods. Criminal profiling is only a kind of prediction, not an accuracy. However, based on this profiling, you can identify the suspect more quickly."

"Xue'er, how did you learn these...advanced knowledge? If you don't have rich experience, it would be impossible to write these profiles, right?"

Fang Jinyu was really curious about the criminal profile that Luo Xue Ning mentioned, but Luo Xue Ning just smiled mysteriously.

"I have read some files and used them to infer the murderer and his actions. I wonder if professionalism can be considered as experience?"

Luo Xuening's words were half true and half false. It was true that she had read many files on ghosts, but her experience could not be learned only from the files. However, those were not important. What was important was to find the murderer.

Fang Jinyu couldn't believe that Luo Xuening's strong analytical ability was actually learned from the files. He smiled helplessly and said.

"Then I'll have to ask Xue'er to do a profile for me."

The repeated calling of "Xue'er" made Jing very dissatisfied. He glared at Fang Jinyu and said coldly.

"Master Fang, Miss Ou is only here to help you investigate the case on behalf of the prince. Isn't it a bit too intimate to address her like this?"

Don't wonder Jing Ci was unhappy, even Luo Xuening felt that she and Fang Jinyu were not that familiar with each other.

Fang Jinyu still smiled calmly: "Comparatively speaking, I am only more intimate with Xue'er, and you..."

Fang Jinyu did not say the following words in front of everyone, but Jing and Luo Xuening both knew it very well. And you just had close contact with the corpse.
