The Crime Squad immediately split up.

Tang Tao drove to the old town of Nanhua City, and found the old yard of Zhou Banshan through the cooperation of the local police station, which is a standard Jiangnan courtyard house, and the house is also a tile house in the last century, with two stone lions standing at the door, the door has been dilapidated, the wall is overgrown with vines, and some unknown wild grasses and wild flowers are blooming.

Xiao Wang, a police officer at the police station, introduced that Zhou Banshan stopped accepting apprentices many years ago, and has been living alone, and when he is nearly eighty years old, he will bask in the sun in the yard when he is free, and rarely go out, and local volunteers will come to see him every ten days.

Tang Tao stepped forward and knocked on the door.

There was no response in the yard.

"Is Mr. Zhou here?" Tang Tao knocked again and raised his voice.

There was still dead silence in the room.

Tang Tao tentatively pushed the door, and the door cracked open, revealing the deadbolt inside, through which you could see that the doors in the courtyard were closed.

It seems to be still resting.

"Old man, someone has come to see you, open the door, I'm Xiao Wang." Xiao Wang also shouted a few times.

But there was still no movement in the house, and Tang Tao had an ominous premonition.

"I'll go in and have a look."

Sophie took two steps back and sprinted, kicked her right foot against the wall, jumped off the wall, and soon opened the deadbolt.

The ground of the courtyard is paved with bluestone slabs, and some things used by practitioners are placed against the wall, such as stone locks, stone hammers, weapon racks, and two wooden stakes. The small courtyard was quiet, and the silence was a little weird.

The three men went separately and knocked on the doors of the three wings.

The door of the main hall was hidden, Tang Tao pushed the door and walked in, a smell of incense and candles came to his face, a portrait was enshrined in the main hall, judging from the text on the side, this person was the ancestor of the Zhou family, and the electronic incense candle on the desk still emitted a faint red light.

There was also an old booklet behind the incense candle, Tang Tao took out the booklet, the booklet recorded the list of disciples recruited by Zhou Banshan, all of which were handwritten with a brush.

He has recruited a total of more than a dozen disciples in his life, and each disciple has a name and a provenance.

Wu Jiahao is called Zifang, this is Zhang Liang's name, Zhou Youbo is called Zijing, this is the name of Lu Su, a famous man of the Three Kingdoms, and Zhao Xiaolei is called Ziqi, which is the name of Zhongzi in Boya and Ziji.

The name on the last page of the booklet was torn off for some reason, judging from the traces, it should have been some years, and there should be some disciples recorded in it.

On the side of the main hall is a side room, where there are several shelves, the bookshelves are full of classics such as the Four Books and Five Classics, as well as many Buddhist scriptures, and there is a calligraphy on the back wall of the side room, on which there is only a cursive "repentance" word.

There is a desk in the middle, and it looks like this is a study.

There is a poem engraved on the desk.

The capital was moved to Wuxiang, Taiyuan became the central government, the national wine Lao Baifen, the state banquet corn soup, the national anthem Shanxi Bang, and the Chinese Wutai dialect.

"Tang Tao!"

Sophie's voice came from the next room.

Tang Tao hurriedly ran in, and saw a white-haired old man on the ground in the room, curled up on the ground, holding a dagger in his hand, and there were several obvious knife wounds in his abdomen, one of which opened a big hole, and the internal organs gushed out, and the blood under his body had already coagulated, and the whole person had fallen in a pool of blood, which had begun to rot, and the air was filled with a choking rancid smell, and it seemed that he had been dead for several days.

"That's right, he's considered Zhou Banshan." Xiao Wang recognized the deceased.

Zhou Banshan actually died, Tang Tao glanced around, the doors and windows were intact, and there was no trace of a fight in the house.

Is this suicide? But if a person wants to commit suicide, why stab himself so much?

On the same day, Han Li and Professor Lei rushed to Nanhua City, and the on-site investigation was carried out immediately.

There was a rain in Nanhua yesterday, and the police did not extract valuable footprints in the yard, but the police still extracted a few clear footprints in the bedroom.

"This person was wearing a pair of Converse board shoes, about 1.7 meters tall, with a thin build, and his left foot was a little outward, he entered through the doorway, sat down at the table, and then walked in front of the victim, circled the table and left the bedroom."

After Sophie finished speaking, Li Xiao completed the 3D composition, and a complete route appeared in front of everyone.

"How did the suspect leave? When I entered, the door was bolted from the inside, could it be that he bolted the door and climbed over the fence to leave? ”

Tang Tao's idea was quickly verified, and the police found a clear footprint on the wall in the northwest corner of the gate, and some curly morning glories on the wall can also prove that someone has stepped on the wall, and there is a stone road outside the wall, which just leads to the road outside.

Kicked over the wall with one foot, it can be seen that this person's body is quite vigorous, and everyone almost thought of one person at the same time, that is, the murderer of Wu Jiahao!

Zhou Banshan is Wu Jiahao's master, so it is entirely possible that the murderer is the same person. Upon inspection, the valuables were all there, except for a long sword hanging on the wall.

The initial autopsy report came out quickly.

Zhou Banshan died four days ago, but the cause of death was suicide by caesarean section.

This result was much more than everyone expected.

"How can suicide have so many wounds? Why did he stab himself so much? Xiao Wang didn't understand.

"Have you ever heard of Trychetron? Tang Tao, please explain. ”

Tang Tao nodded and said: "Trial cutting refers to the suicide when he commits suicide because of psychological factors, so he uses a sharp weapon to carry out tentative stabbing on his body, so there will be one or several wounds of different sizes on the corpse, this kind of wound is mostly seen in the chest, abdomen and neck, if he is determined to commit suicide, then the wound will be deeper than one another, until he kills himself." ”

"And how do you explain the lateral wound in his abdomen? How do I feel...... It feels weird, like a Japanese samurai committing suicide. Xiao Wang was still a little confused.

"Maybe this is to make my death faster, the detailed autopsy will not be able to give an answer until I finish the autopsy, take the body away."

Han Li turned around and left, and the assistant Xiao Duo immediately asked people to put the body in a bag and carry it out of the yard.

A lot of people gathered at the gate of the courtyard, and the old director of the former police station also came, and he and Zhou Banshan were good friends and had a very good relationship.

From the mouth of the old director, everyone learned that Zhou Banshan's ancestral home is Shanxi, he later moved to Nanhua City after changing his household registration, several apprentices were also recruited in Shanxi, after coming to Nanhua, he only accepted one disciple, this person is called Huang Shengping, Zhou Banshan named him Wu Nian, Henan Pingxiang, this person is not tall, taciturn and rarely speaks, five years ago when the master and apprentice were traveling in Nantai Mountain, Huang Shengping fell off the cliff and fell into the Qinglong River.

At that time, the police dispatched a large number of police forces to search and did not find Huang Shengping, and later characterized him as missing, because he did not have an ID card, the police have not been able to determine his true identity until now, and it is also because of this incident Zhou Banshan was hit hard, after which he announced his retirement in frustration.

Huang Shengping has disappeared for many years, and his information has long been cancelled, and this person is dead in the legal sense.

What is strange is that this Huang Shengping's height and body type are almost the same as the murderer inferred by Sophie.

How could a dead man appear in Zhou Banshan's house? Didn't he die at all?

Sophie and the others followed the old director to Nantai Mountain, while Tang Tao stayed at the scene of the crime and carefully flipped through Zhou Banshan's collection.

The place where Huang Shengping fell off the cliff was located under a big tree on the highest observation deck of Nantai Mountain, this place was hundreds of meters away from the river, and it was Wu Jiahao and Zhao Xiaolei who had been killed who called the police, and the two reported that Huang Shengping had an accident when he crossed the chain to take pictures, and the police picked up Huang Shengping's mobile phone on the edge of the cliff at that time, so it was judged that Huang Shengping should have fallen off the cliff from that place.
