Glancing at the room number, I quickly looked away, but my reaction still couldn't escape Xu Yi's eyes. She asked me if I thought there was something wrong with the house number of "444", I smiled wryly and shook my head, I have been exposed to more cases like this, and I am very sensitive to these things.

Xu Yi and I walked into the room, and Zhou Sheng was sitting on the sofa, looking like he was going to die. Jiang Jun and another criminal policeman had already started to investigate. When we came in, they had just checked the living room, and Jiang Jun told me that they had found no valuable clues in the living room, and asked me if I wanted to take another look.

I looked around, this family of three lived a very simple life, the layout of the living room was very simple, and there was no suspicious place to hide things. After a brief little more circle, we focused on Zhou Xiaoruo's room, and Zhou Sheng got up from the sofa and led us into Zhou Xiaoruo's room.

"Xiao Ruo doesn't go out of the room often, and when we come back from work, he sits in the room and studys...... After eating, he will go back to reading again......" Zhou Sheng said, his eyes red again. Zhou Xiaoruo went out with Zhou Sheng and his wife during the day, ate in the school cafeteria at noon, and would take something to cushion his stomach when he came back in the evening, and then eat another meal after Zhou Sheng's parents came back to cook.

After turning on the electric light in Zhou Xiaoruo's room, the first thing we saw was a desk, which was neatly stacked with teaching materials. Zhou Xiaoruo's room is also very simple, a bed, a desk, a wardrobe, and nothing else. The quilt was neatly folded, but there were a few pieces of clothing scattered on the bed.

"Has this room been moved?" I asked.

Zhou Sheng shook his head: "After Xiao Ruo disappeared, no one has ever entered this room, and the layout of everything here is the same as when Xiao Ruo disappeared." ”

Jiang Jun handed me the medical gloves he had prepared in advance, and after putting them on, I immediately walked to the bedside. The clothes scattered on the bed looked like pajamas, I asked Zhou Sheng when Zhou Xiaoruo wore these clothes, and he told me that Zhou Xiaoruo would change into pajamas when he went home.

I thought of something, lowered my head and looked for it, and sure enough, there was a very dirty set of clothes under the bed, which was the school uniform of Shihua Middle School.

"When should I wash my clothes?" I asked.

Everyone looked at me puzzled, they didn't know why I was asking such a question. Zhou Sheng was stunned for a while, I asked again, and finally, he told me that their lives were very regular, and although they came back late, their clothes were washed once a day. I picked up the dirty school uniform and continued to ask, "Then this school uniform was changed by Zhou Xiaoruo that day, right?" ”

Zhou Sheng nodded.

"Professor Li, what do you mean?" Jiang Jun scratched his head, he couldn't understand what I was asking.

Those who were there knew what I was thinking. Xu Yi asked for me: "Mr. Zhou, do I have to wear a school uniform to enter Shihua Middle School?" ”

Asking this, Jiang Jun finally understood a little. Under inquiry, Zhou Sheng told us that Shihua Middle School requires students to wear school uniforms every day, no matter day or night, students must wear school uniforms before entering, and the school has issued several sets of school uniforms to each student for washing.

"Does Zhou Xiaoruo like to wear school uniforms?" Xu Yi asked again.

Zhou Sheng denied: "How can any student like to wear school uniforms, when he is not in school, Xiao Ruo does not wear school uniforms." ”

With this analysis, I finally have a clue.

"Jiang Jun, arrange for some people to be investigated near Hua Middle School." I said to Jiang Jun, who was a little excited, and immediately called to inform him.

From the surveillance, we can't see whether Zhou Xiaoruo's school uniform is clean or dirty, and now that I think about it, Zhou Xiaoruo is not wearing the same school uniform when he enters the door and goes out. He was wearing the school uniform that was thrown under the bed at school that day, and he wanted to change into pajamas, but suddenly wanted to go out, so he changed into clean clothes again.

The room is so clean, Zhou Xiaoruo should not be a sloppy person, the reason why he threw his pajamas on the bed, and didn't even have time to clean up the dirty school uniforms on the ground, was because he was in a hurry to go out. If Zhou Xiaoruo, who doesn't like to wear school uniforms, changes into a clean school uniform, it is likely that his destination is Shihua Middle School, because the school cannot enter without school uniforms.

"Professor Li, you're amazing!" Hearing my analysis, Jiang Jun praised.

"Don't be happy too early, this is just inferred from common sense and Zhou Xiaoruo's living habits, and it may not be correct." As I spoke, I walked over to Zhou Xiaoruo's desk and continued to check. My words extinguished Jiang Jun's fledgling enthusiasm, but he didn't care, and followed my footsteps to search.

The desk has a drawer, and when you pull it out, there is a geometry textbook lying inside. The size of the geometry textbook is different from other books, I immediately recognized it, this book is the one Zhou Xiaoruo held in his hand when he came back, the book cover is white, but it turned gray in the surveillance screen.

I opened the book, a piece of paper fell to the ground, Xu Yi squatted down to pick it up for me, and when she looked at the white paper, her face suddenly changed. Xu Yi's expression gave me an ominous premonition, and I immediately snatched the white paper in Xu Yi's hand, and my brows were deeply locked at this look.

This painting is highly similar to the one painted by Zhu Li......

The one painted by Zhu Li has very rough lines, and we can only vaguely identify the shapes, but the one in the textbook is very realistic. It is still a pencil drawing, and the background of the painting is a dirt slope, on which a bamboo pole stands, and on this bamboo pole hangs a person.

The man was unclothed, and the bamboo pole went through his crotch and out of his mouth. According to the hairstyle and facial features, I found that the person in the painting resembles Zhou Xiaoruo, and the most bizarre thing is that the person in the painting is the same as Zhou Xiaoruo's corpse, with both eyes squinting towards his right hand.

"What's going on! What's going on! "When Zhou Sheng saw this painting, his emotions became excited again, and he reached out to grab the painting in my hand, but my reaction was very quick and I immediately dodged it.

Zhou Sheng wanted to come up and take it again, but Jiang Jun clasped his arm. Zhou Sheng wailed: "Who is it! Who harmed my child! Tear that picture up! ”

The content of the painting on the paper deeply stimulated Zhou Sheng.

"Mr. Zhou! This is very important physical evidence, if you don't want your son to die in vain, calm down! My heart also made waves, and I shouted at Zhou Sheng.

After being drunk by me, Zhou Sheng finally calmed down a little, Jiang Jun helped Zhou Sheng to sit on the edge of the bed, and I looked at the painting more carefully. I thought of a possibility, as soon as I opened the book, the painting fell down, and Zhou Xiaoruo held the book all the way, and must have found the painting as well.

Could it be that what he has been staring at is not the content of the textbook at all, but the painting?

"Li Ke, does it have anything to do with Zhu Li?" Xu Yi walked out of the shock, she asked.

"I don't know." I handed the painting to Jiang Jun, who took the bag and put it up, he was very careful, for fear that Zhou Sheng would lose control of his emotions again and destroy this important physical evidence.

My head was a mess, and there seemed to be some underlying connection between case after case, and I found that I simply couldn't figure it out.

"Li Ke, I think what Shen Nuo said is right, don't think about things too complicated." Xu Yi took my fingertips and said.

I remembered what Shen Nuo said to me in S County, those words, someone dragged her to tell me. The man told me to clear up the clues one by one, and not to always think about things. My head hurt a little, rubbing my temples, I nodded at Xu Yi, whether there was a connection or not, the top priority was to solve this skinning case first.

We checked again, and this time, we didn't find any other valuable leads.

When I left Zhou Xiaoruo's house, I glanced at the dark entrance of the building again.

Zhou Sheng was supported by the accompanying criminal police, Zhou Xiaoruo's death hit him hard, and when he saw that painting, he seemed to see the scene of Zhou Xiaoruo's tragic death again. It took a lot of effort for the criminal police to stuff Zhou Sheng into the car.

We immediately went back to the police station, and the policemen who watched the surveillance video for a day finally brought us an important news, they found that a few days before Zhou Xiaoruo's death, a man and a woman always knocked on Zhou Xiaoruo's door......
