City C is a relatively comfortable city. Liu Yi rented a slightly simple house outside the Fourth Ring Road and devoted himself to writing all day long. His only pastime was to enjoy the cool air on the balcony of the rental house.

"Dangdang!" A sound of unrhythm knocking broke the silence inside the house.

Liu Yi scratched his head and walked slowly to the door. The knock on the door continued. He glanced at the cat's eyes, shook his head, raised his hand to open the door and asked impatiently: "Why are you again?" In front of Liu Yi was a middle-aged man with messy hair and yellow and thin face. Although he was neatly dressed, he always felt that he was particularly awkward from where he looked.

The man dared not look directly at Liu Yi, and suddenly looked up: "Dispatch, is your house leaking? Uh, I mean, or I heard some strange sound, I... my house was blocked from the water. Where is your house?" Liu Yi saw that he was incoherent and talked nonsense.

"You come here five times a day! I said everything, why would my house leak if the water is blocked?" Liu Yi closed the door impatiently.

"It's really sick!"

Liu Yi looked at the cat's eyes curiously again. The middle-aged man outside the door seemed a little disappointed. However, he did not turn around and leave immediately. His left hand was about to lift it up and fall, while his right hand kept covering his ears, his face twisted, as if he was in great pain.

The man wandered around the door of Liu's family for more than twenty minutes before leaving.

Night is the most suitable time for writing, but every eleven o'clock, the jingle sounds and rapid footsteps will come upstairs, back and forth. A while ago, you could hear the voice of a woman. The old house was poorly sound insulation, and Liu Yi was also helpless.

Liu lit a cigarette, walked to the balcony and cursed, "I'm crazy."

This old house only has the fifth floor. Liu Yi lives on the fourth floor. There is only one family on the fifth floor. The other family was also bought by the middle-aged man. It was said that it was changed into a merged house.

The smoke from the cigarette in Liu Yi's hand floated like a wisp of walking mist, slowly drifting upstairs.

"Ah! Who? Don't, don't!"

A pungent smell mixed with waves of white smoke.

"I deserve it, I deserve it, now I see how you pretend! What? Will you keep listening to me? Stinky bitch, stop lying to me!" The middle-aged man seemed to be talking to himself in front of the mirror, and his hands were still catching something.

"Ah? Is this me? Who are you?" The middle-aged man's expression changed and he immediately changed like a human being. He stroked himself in the mirror with his right hand, and grabbed the girl next to him tightly with his left hand and rubbed his face a few times, "You are the most obedient, my little baby."

Immediately after a burst of arrogant laughter, the originally quiet toilet instantly became noisy, and even downstairs could hear it.

The dim light gradually lost its light, and the sound also disappeared.

In the early morning, the sun was shining brightly and the spring breeze squeezed in through the cracks in the window. Liu Yi, who had wanted to sleep until eleven o'clock, was woken up by the sound of footsteps.

"Is it possible to sleep if I can't let you sleep!"

Liu Yi walked out before he put on his slippers. When he opened the door, he saw that there were many policemen standing in the corridor, as well as some good neighbors. The cordon had sealed the staircase from the fourth floor to the fifth floor.

A strong smell of blood came from the upper floor.

"Xiao Liu? Why are you here?" Liu Yi looked up, rubbed his eyes, and said with a smile: "Captain Wang! Why are you?"

"Is someone reporting the case early in the morning? Why? Didn't you hear the sound of a police car?" Liu Yi's unshaven beard, scented and serious man named Wang Jianguo. He is the leader of the serious crime team in the district. He is almost forty and has not been married.

He met Liu Yi because of a campus kidnapping case. After that, Liu Yi kept helping Wang Jianguo solve some cases, and his relationship was quite good. Liu Yi also became a "special guest" of the police station.

"What's wrong?" Liu Yi asked curiously.

"Murder, the forensic doctor will come in a while." Wang Jianguo said this and walked upstairs quickly.

Neighbors kept sayings from the corridor. Occasionally, you can hear "What happened to Professor Li?" "No! Professor Li is so upright!" "I was watching him take a walk downstairs some time ago!"

"Why haven't you followed?" Wang Jianguo called Liu Yi while holding the railing.

Liu Yi was stunned for a moment, put on his shoes, and ran over.

Liu Yi crossed the cordon and walked into the strange house on the fifth floor with Wang Jianguo. He suddenly shuddered. Although he had never been to this room, he was so familiar.

In addition to the smell of blood, there are other smells mixed in the house. There are some paintings hanging on the wall, and the two rooms on the left and right are open. The room on the right seems to be the victim's painting studio, and the study on the left is.

"Captain Wang, do you smell it?" Liu Yi kept inciting with his hands, trying to gather the rare smell in front of his nose.

Wang Jianguo obviously didn't smell it, and kept watching around to see if there were any clues.

"Master, the identity of the deceased has been verified!" At this time, a strong young man with flat head, thick eyebrows and big eyes came out of the house.

"Tell me! Xiao Xu!"

Xu Wei, after graduating from the police academy, was assigned to the police station under Wang Jianguo and followed Wang Jianguo. The two of them usually called each other masters and apprentices. They used to be brothers and brothers with Liu Yi, but Liu Yi helped solve the case several times, stealing the limelight and began to be a little jealous of his detective mind.

Xu Wei glanced at Liu Yi, "Why is he here?"

"Speak quickly, stop talking nonsense!"

"The deceased Li Wenzhong, male, 52 years old, lives alone, is a professor at the nearby art university here, and has no criminal record. Some of the scenes..."

After hearing this, Liu Yi told Wang Jianguo about Li Wenzhong's frequent knocking on his door during this period.

Wang Jianguo dragged his chin and said, "It seems really strange! Xiao Xu, why didn't you continue?"

"Master, you should take a look at the dead first!" Xu Wei seemed a little timid when he said this. Wang Jianguo and Liu Yi walked slowly towards the toilet.

The scene in front of him instantly shocked the two of them. Li Wenzhong was naked, cut from his chest to his belly, and sutured, his lower body was cut off and threw it into the bathtub. Blood on the ground filled the entire bathroom floor.

Li Wenzhong's internal organs were dug out and put them on the ground, and placed neatly beside him, but his stomach was indeed bulging. He stared at the door of the toilet, his mouth wide open, as if he was frightened.

The word "damn" is written in blood on the toilet mirror.

Liu Yi walked up, squatted down, looked at Li Wenzhong's body from head to toe, and then carefully observed the internal organs placed on the ground.

"On the surface, the victim did not fight with the murderer, and the two of them might know each other. The fatal injury in the chest directly penetrated the heart. The murderer was quite patient. After taking out the internal organs of the deceased, he sewed his stomach up again. There was a filling in his stomach. What should the murderer put in it. The blood flowing out of the internal organs did not completely solidify, and the death time should be between three in the morning and five in the morning." These are all from the surface.

"Xiao Xu, have you found the tool for committing the crime?" Wang Jianguo turned around and asked.

"There is no master, I have been searched for the scene, no!"

"The murderer brought the crime tool to the door, just like working at home, and he would definitely not stay here! Judging from the word "mirror", it is a vendetta." Liu Yi stood up.

"You are his neighbor, and you didn't hear any sound last night?" Xu Wei seemed to doubt the authenticity of Liu Yi's narrative.

"I'm really sleeping very hard." Liu Yi suddenly turned around and looked at the location of the toilet handbasin, just facing the location of the toilet downstairs.

"Leakage? The sewer is blocked? Could it be?"

"What's wrong with Xiao Liu?" Wang Jianguo saw Liu Yi turn on the faucet, but the water did not flow down quickly but gradually filled the entire handbasin.

The water pipe was a plastic hose, and Liu Yi easily took it off, and a foul smell hit him. Several of the detectives on the spot were vomiting continuously. The smell of blood covered the smell of the sewer.

"Is this?" Wang Jianguo asked.

Liu Yi endured the stench. In order not to destroy the scene, he walked to a corner of the toilet and shook it a few times. He saw some minced meat and many maggots fell inside.

"Corps?" Liu Yi put down the water pipe, squatted on the ground, retching for a few times, and then fell into deep thought.

"Liu Yi, you are talking! So many people are waiting for you here!" Xu Wei was still anxious.

"Xiao Xu, OK! Go and check if there are any useful clues in the deceased's house." Although Xu Wei was a little unhappy and Liu Yi snatched the limelight, his master spoke and had to glar at Liu Yi and leave the bathroom.

"Xiao Liu, have you discovered anything?"

"Brother Wang, you need to go back and check these corpses, and they should not be the victim!"

Wang Jianguo nodded.

"Who reported the case?" Liu Yi continued to ask.

"It was Li Wenzhong himself, and the time for the report was six o'clock this morning. It seemed that the murderer called the police on Li Wenzhong's phone. The sound on the phone was not like that of a person in his fifties."

"The person who reported the case is the murderer. The murderer called Li Wenzhong's mobile phone. You should not be able to find the murderer. The murderer stayed here for a while before calling the police. In addition to dealing with the body, he might be looking for something or enjoying the scene in front of him to satisfy some desire in his heart."

When Liu Yi entered the toilet, he also carefully observed the toilet structure and the items inside.

"This toilet has been renovated, and it should be considered a big deal for such an old building. Judging from the toiletries in the toilet, the deceased should be a very particular person!"

“Very particular?”

"Yes! It should be said that he is good at taking care of himself! He often socializes." Liu Yi pointed to the skin care products and perfume behind him, and then walked to the deceased and continued: "But these skin care products still did not cover up his aging. By the way! There are also these things." Liu Yi pointed to the two little girls' underwear and continued: "The victim is in love.                                                                               

"From the direction of the blood and the footprints on the blood, it can be seen that the victim may have been injected with drugs by the murderer when he came out of the toilet. The victim's pupils were enlarged and the whites of his eyes were covered with blood. It should be because he was overly tired on weekdays and was frightened again at the time of the incident." Wang Jianguo and others followed Liu Yi's hand and looked at every place he said.

Liu lit a cigarette, took a deep breath, waved his hand and said, "You guys do it yourself! I have to go back and write!"

"Wait! Frightened? Didn't this guy live alone? Who can scare him? Could it be the murderer?" Wang Jianguo looked around for something while observing the corpse.

"Brother Wang, it may be the murderer or himself. The victim is likely to have mental illness!" Liu Yi said, pointing to the mirror on the toilet basin.

"Scared yourself?" Wang Jianguo was a little suspicious.

"Yes, when will you scare yourself? Or you see your internal organs being dug out, the victim may have her stomach cut when she was half awake." The detectives present were stunned.

Liu Yi continued: "From the scene, the murderer was quite calm. Judging from the neatness of the knife edge and the cutting of the internal organs, he should have some anatomical knowledge, but it is by no means professional, and may be self-taught. The murderer acted cautiously and agilely, which is not the first time he committed a crime."

"Let's go back to the police station first! This case is a bit strange, let Xu Wei handle the rest!"

"What? I still want me to get involved? I don't have much time!"

"Come on! It happened under your nose. Do you have to figure it out clearly? There is another thing, your good brother Liu Xing is missing, right?"

"Missing? He was indeed not contacted for several days."

"Someone reported the case!" Wang Jianguo then lit a cigarette.

"Who? Are there any clues?" Liu Yi asked with concern.

"It was his girlfriend who reported the case, and there was no clue yet." Liu Yi was in a state of confusion, and his younger brother disappeared at this time.

After several people returned to the police station, Liu Yi hurriedly asked: "Xiao Jia reported the case? Have you interrogated her?"

"The interrogation was immediately, but there were no favorable clues." Wang Jianguo seemed quite helpless.

Liu Yi sat down slowly, lowered his head, and remembered the scene of growing up with Liu Xing in the orphanage. At that time, the two of them had a miserable life. In the orphanage, they were not only bullied by older children, but sometimes they were scolded by teachers.

"Xiao Liu! I know that you have deep brotherhood, and I will do my best to help you."

"When Liu Xing went out to have dinner with me a while ago, he said he would go out to sketch with a professor named Li, and it should be him."

"It seems that the two of them should be very familiar with each other. I have sent someone to the school to investigate. You are also from this school, why don't you know this teacher?"

"I don't know you, maybe I transferred to our school after graduation!" Students with questions like Liu Yi often don't stay in school, so how can they get along well with the teacher?

Wang Jianguo usually looks sloppy, but when he acts, he is very efficient.

Liu Yi repeatedly asked himself questions in his heart, why did the murderer spend this trouble to kill someone? If the murderer knows the victim, what is their relationship?"

At this time, a detective ran in from outside and said in a panic: "Team leader, team leader, it's not good, come and have a look."
