"We seem to have...suddenly figured out the murderer's motive for the murder." Qingguo added naggingly. Leng Chuan nodded silently in agreement.

Lu Qingfan glanced at Ran Piao with unknown meaning, "First check the place where the crime occurred, and Yun Zuo will do the autopsy."

Don't blame Mr. Cai Ran for hesitating just now. This matter involves the marriage of many nobles. If Prince Cheng is really secretly assisting the marriage of aristocratic families and reaping benefits from it, then Prince Cheng may not be innocent when it comes to the death of Yundie and Yan Jun.

He was secretly annoyed that he had ignored this matter and now another person died.

Yun Xi also thought of this, and looked at the middle-aged man lying on the ground with a complicated expression: he had handsome features, and his wide-open mouth and bloodshot eyes gave him a very ferocious death look.

She took a brief look at the wound on Prince Cheng's neck and sighed: "The murderer strangled Prince Cheng around an hour ago. The murder weapon was the same as when Yan Jun died..."

The little finger as white as green onion pointed to the new gauze on the ground: "That's it."

If she hadn't known that Gao Changdong had been exiled in the prison on a certain day, Yun Xi would have almost thought that he was out to avenge Miss Tan again.

The exact same modus operandi, the exact same tools, and a very obvious sense of revenge cannot help but make people think a lot.

"Go and interrogate Princess Yuanyue, Yu Zhi, and all parties involved in the previous case about their movements an hour ago, and report back as soon as possible."

Lu Qingfan ordered sternly, and Leng Hai and Leng Chuan immediately followed the order and left.

Ran Piao's expression changed drastically: "I asked specifically before I came here, Mr. Gao... Gao Changdong is indeed still in the prison of the Ministry of Punishment."

"It's not him," Yun Xi said softly.

Wearing transparent sheepskin gloves, Hao Wan turned over the deceased's clothes, looked at the mouth and nose, and carefully touched the neck bone. Yun Xi said loudly: "The murderer is a master."

Yun Xi tilted her head thoughtfully, "My martial arts skills should be similar to those of adults, and strangling Prince Cheng is just a joke."

Lu Qingfan: "...Thank you for the compliment."

Prince Cheng and Yan Jun seem to have similar death signs, but they are completely different.

Gao Changdong and Yan Jun were in a confrontation. Gao Changdong was at a disadvantage. He used all his strength to strangle Yan Jun, who was tall and strong after eating "Heart-Eroding Magic Orchid".

Yan Jun's facial features were congested, and the injuries to his neck bones appeared gradually during the murder.

The Chengjun Prince in front of him was just the opposite: he had no power to fight back against the murderer, and his neck bones were broken in an instant, and his ferocious facial features retained the shock of his life.

In the short half hour before they arrived, symptoms of suffocation such as bloodshot eyes gradually became clear.

"Yan Jun's neck bone was fractured in a progressive compression manner, with many bone fragments. King Chengjun died instantly, and the fracture of the neck bone was quite neat, with very few bone fragments. This proves that Gao Changdong was not the murderer of King Chengjun."

The more Yun Xi spoke, the more solemn her expression became. She didn't even need a caesarean section to do an autopsy before she knew it was over.

"What?" Lu Qingfan asked in surprise when he saw Yun Xi standing up.

"I can't provide many clues. Even the autopsy is just a routine matter." Yun Xi felt a sense of powerlessness for the first time: "The murderer's technique was clean and neat. He killed people without any unnecessary movements. Even the murder weapon..."

She picked up the murder weapon gauze with her gloves: "It was also cut with internal strength."

Because she is not good at internal energy, Yun Xi has almost no way to start.

Lu Qingfan nodded when he heard this: "Forget it, let's do something."

Yun Xi nodded. She told the worst possibility, and then she and Qingguo moved Prince Cheng's body to the next room for a caesarean section for autopsy.

Here, Lu Qingfan continued to observe the side room, while listening to the words of Ran Piao and Qiong Fang, the steward of the Villa.

The death of his master and the loss of lives of the guests in Qiongfang Villa are of different weight to these servants.

"...His Royal Highness the County Prince has previously ordered that it be renovated without any changes. Now the decoration is the same as before. I really can't see anything different."

"Where are the people? Has anyone suspicious been here? Did you see anyone that His Highness met?" Ran Piao asked.

The person in charge just said that he had not seen it yet.

Lu Qingfan looked around the room and his face became increasingly ugly.

Finally understanding why Yun Xi was so sure before even doing an autopsy, there was probably no gain: he didn't find any useful traces in this room.

The previous murder scene demonstrated almost all the entanglements between Yan Jun and Tan Yundie. Lu Qingfan and Yun Xi also gradually deduced the possibility of the case based on these clues.

Now, the paint at the crime scene is still fresh, the decorations are all new, and the carpets have been replaced. However, the murderer did not leave even a single footprint except for a corpse and a piece of gauze, the murder weapon, which was severed from the inside.

"It shouldn't be." Lu Qingfan firmly believes that wherever people go, they must leave traces.

Not giving up, he took Ran Piao and searched the house again.

Still nothing.

An hour and a half later, Yun Xi's master and servant came out of the house with a depressed face, and looked at Lu Qingfan, who was sitting in the pavilion with an ugly face, and realized that both of them had hit a wall.

The murderer not only knows how to hide, he is also an expert in killing people.

"Prince Cheng made Xiao Long Bao and Tofu Pudding at Liu Ji Baozi Shop near the Prince's Mansion this morning." Yun Xi sat down on the stone bench, and Ran Piao politely handed her a cup of tea.

Yun Xi thanked her and drank, then continued: "In the afternoon, His Royal Highness came to the Villa to check on the renovation progress. There was a little bit of paint on the corners of his sleeves and the tips of his fingers."

If Prince Chengjun had confronted the murderer before his death, the murderer's clothes might have been stained with a little paint.

But this clue is like looking for a needle in a haystack, and it is extremely difficult to find.

"After about half a cup of tea, the housekeeper entered the room and found the body of His Highness the County Prince."

Currently, Yun Xi only has these few clues.

Lu Qingfan had a stern look on his face, "The criminal is very skilled in martial arts and has no trace of his actions. Does it sound familiar to you?"

"Sir, you mean..." Yun Xi's eyes widened in surprise: "Merchant ship?"

Back then, several guests disappeared for no reason on the merchant ship. Isn't it just like the case of Prince Cheng, where the murderer was invisible and left no trace.

Acting intuitively, Yun Xi's clear and gentle face of Huajian Ying once again appeared in her mind.

So suspicious...

"Sir, what kind of merchant ship is Yun Wu Zuo?" Ran Piao asked.

Qingguo talked about the previous case of the merchant ship in a few words.

"Then it's not related to Qiongfang Villa, but the murderer killed him at will. In order to avoid exposing his identity, he deliberately imitated Gao Changdong's method of killing?" After Ran Piao finished speaking, he was the first to deny it: "That's not right."

The motive points to such an obvious murder, how could it be done randomly?

For a moment, everyone in the pavilion fell silent.

"That's quite simple. Who will benefit the most from Prince Cheng's death will be the most suspicious."

Lu Qingfan stood up and asked Ran Piao to notify the county prince's palace to bury the body.

Yun Xi refused to give up and wanted to visit the place where the crime occurred. Lu Qingfan agreed.

Lu Qingfan and Ran Piao went their separate ways and left the carriage with Yun Xi's master and servant.

Lu Qingfan had carefully inspected everything around the place where the crime occurred. Qingguo didn't know what else to look at, so he could only look around corner by corner. If he found something, he would ask Yun Xi if it was of any use.

Yun Xi held a magnifying lens in her hand and walked around the place where Prince Cheng's body was found.

Soon, she found a few hairs under the table, between the gaps in the carpet, and near a very inconspicuous furniture hinge.

Yun Xi put her hair in the sun and recognized the hair of Housekeeper Bieyuan, Prince Cheng, Lord Ran and Lu Qingfan.

There is only one strand of hair, strange and familiar at the same time.

Yun Xi stroked her hair bit by bit under the sunlight, and she always felt that familiar feeling lingering in her mind, and she just missed it.

"The ancients used their hair to show their love. Miss, you are using your hair to distinguish criminals from your own. It's really interesting." Qingguo was lying on the ground looking aimlessly while teasing his lady.

Yun Xi's mind buzzed, and she suddenly said: "I remembered it!"

Qingguo was startled, "What?"

"Flower House."

Yun Xi twisted the important hair evidence and said in a deep voice: "The boss of Hua Lou Yi Rong's hair has this texture and color!"

This person has been to the place where the crime occurred. He may be the murderer of Prince Cheng!

[Author's digression]: Hualou boss:???

Yun Xi: I caught it, your hair.
