"Little madman, what's wrong?" Lao Sun looked at Xiao Yi's frowning brows and said.

"Nothing? Does my grandson need my help? Xiao Yi put the letter in his underwear pocket and said.

"I want you to help me...... I'm looking for you to come in and I'll give you this letter, get out of here, and I'll cook the fish in a moment." Lao Sun said and skillfully poured oil in the pot.

Xiao Yi turned around and walked out of the kitchen, watching everyone happily discussing something, and when he got closer, it turned out to be the mess about the last time he was locked up in the archives.

"That's a good point, but the theme of today's dinner is still the case." Xiao Yi said with a smile.

"Captain, Jiang Lin went out with you today to find new clues, let's talk about it, let's discuss it together." Liu Xiaodong said.

Xiao Yi sorted out the thoughts in his mind and told all the clues and questions he found today. The crowd was lost in thought......

15 minutes have passed unconsciously, Lao Sun came over with a fish hot pot, saw that everyone was thinking and didn't make a sound, put down the hot pot, and returned to the kitchen.

Zhang Ruoyun was the first to break the silence and said: "According to the captain's reasoning, Shang Wu's death was entirely because of himself, or more precisely, because of Shang Ren's inadvertent words, which caused the murderer to know that Shang Wu had bought a nylon rope again."

Lin Xiaoxiao continued: "In other words, the murderer actually didn't want to kill Shang Wu."

"Tomorrow, Wang Jun, you and Zhao Wen will go to the place where the leaves of the banyan tree are located to inquire about the source of the hollow sample. Lin Xiaoxiao will find a way for me to find Wang Hong's social records for a week tomorrow, and hack his mobile phone directly like last time. Xiao Yi said while eating fish fillet.

"Captain, isn't it a bit illegal to always hack other people's systems to obtain information, in case it is known by Bureau Liu." Lin Xiaoxiao said hesitantly.

"If you know, say that I asked you to do this, and I will bear all the consequences." Xiao Yidao.

"Lao Zhang, tomorrow you go to the hospital to check Wang Hong's physical examination information, I remember that the city has just done a comprehensive physical examination in the past few days, it is best to make a copy back."

"No problem, but can I ask why?" Zhang Ruoyun said suspiciously.

"Because in my imagination, there is only one person with motive and time for Wang Hong, Wang Jian's son, and he is 90% likely to be the murderer of this murder." Xiao Yi said flatly.

When everyone heard this, some were puzzled, some suddenly realized, and some showed really such expressions.

Far away in the office of Qingtian Group, Wang Jian saw the report in his hand, and his brows were twisted into a Sichuan character.

Because it is recorded: "The person who robbed the report sheet and injured the employee a week ago was his son Wang Hong."

He really couldn't imagine that his son was behind all this, and also threatened some employees and management in the company, asking them to hide their whereabouts, if he hadn't forced him to ask, and there were technicians to restore the lost files from monitoring, maybe he wouldn't suspect Wang Hong until the incident was over.

For such a long time, since he can find clues to find Wang Hong, then the mad dog Xiao Yi will not find it, and he will come over with a search warrant to search for evidence tomorrow at the latest, but I don't know if Wang Hong's kid is clean or not.

He must have a good talk with Wang Hong when he goes home today, this matter is related to the rest of his life, and he can't let Xiao Yi easily bring people back to the police station no matter what.

Suddenly, Wang Jian seemed to think of something, Wang Hong would not find what he brought back from abroad last time at home, if this is really the case, everything can be explained.

The next day, Xiao Yi came to Shang Ren's house, and yesterday because it was too late, Jiang Lin did not bring Shang Ren back to the police station.

Looking at the dirty environment around him, he could know that Shangren's economic situation was not very good, and he knocked on the door. After a long time, the door was opened by an old man.

Seeing that his face was full of sadness, it seemed that it hadn't been long since he cried, Xiao Yi said: "Uncle, I'm a policeman, and I came here today to understand the situation."

The white-haired uncle hesitated for a long time but opened the door and invited Xiao Yi to enter the door. The environment inside the door is very different from the outside, although the furniture is very shabby but it is cleaned everywhere, Xiao Yi looked at the family photo on the wall and said: "Uncle, is Shangren born to Shang Wu?" Why is there no his mother in the photo? ”

"Alas, Shang Ren was picked up from the garbage heap by Xiao Wu, and he was happy for a long time at that time, thinking that this was the hope that God had given him to pity him." The old man said hoarsely.

"Sang-in is at home today...... I'd like to ask him a little bit more about it. Xiao Yi said.

The old man went to a room and opened the door and called out the people inside, Xiao Yi saw Shang Ren for the first time, the other party was very strong, and his height was more than 1.6 meters, but the red circles under his eyes proved that he had just cried for a long time.

"You talk first, I'll make you some hot tea......" The old man finished and walked straight to the kitchen.

"Shangren, I want to know something about Wang Hong, starting with you buying a nylon rope." Xiao Yi went straight to the point.

Shang Ren looked at Xiao Yi a little puzzled, not expecting Xiao Yi to ask him this question.

"A month ago, because the class needed nylon rope to arrange some things, Gonghong told me that there were some things sold in the store outside the school gate, and then I took the class fee to buy them.

At that time, I thought of one thing, "Wang Hong is the son of Wang Jian of Qingtian Group, so he must know that there is a shutdown at his construction site." Looking at the nylon rope in my hand, I asked the store owner if he had a good quality nylon rope, so he took out a nylon 66 one. Shang Ren said.

"Later, you bought a little more, went back to school and asked Wang Hong about the construction site, I want your father to go to the construction site to pick up some waste materials to sell, right, and Wang Hong also told you more than one construction site, but Shang Ren chose the sky blue construction site." Xiao Yi answered.

Shang Ren looked at Xiao Yi in surprise, unable to believe how Xiao Yi knew these things.

"Wang Hong has something abnormal in the past month, or what abnormal words he has." Xiao Yi asked.

"I remember a month ago he asked me if I believed in myths, and I was puzzled but answered yes. He was a little emotional, and I thought it was something else that I didn't pay attention to......

By the way, I've recently noticed that he's more concerned about an old fountain pen and plays with it almost every day. Shang Ren thought for a moment and said.

"What kind of fountain pen? Did he write something with that pen? Xiao Yi said in his heart.

"The English name above has disappeared, looking at the style should not be domestic, the style is a bit old, it looks like a foreign product in the eighties and nineties. As for writing, I haven't really seen him write it, but he cherishes the pen. Shang Ren said.

It seems that the thing that Wang Jian brought from abroad was the fountain pen, but for some reason it came into Wang Hong's hands. Could it be ...... Xiao Yi had a bad thought in his heart.

"Did you tell him about nylon rope the other day?" Xiao Yi asked.

"Well, at that time, I casually told Wang Hong about the nylon rope my dad used when he went to the construction site, and he himself asked me where I bought it a week ago, and I told him.

He came to the school gate himself to buy a little more, but since he came back from the construction site, something was wrong, and he seemed a little suspicious. Shang Ren said.

"You casually said that you killed your father, even though he was not your biological father." Xiao Yi was silent for a long time and said.

"What do you mean by that?" Shang Ren's tone was a little unkind.

"Why do you think your father was able to enter the construction site so easily...... Why was he suspicious when he came back, haven't you thought about any of this? Xiao Yi said.

"Didn't Wang Hong say hello in advance......" Shang Ren said uncertainly.

"It's too simple, he told you a lot about the situation of the construction site, and it is impossible to say hello to every construction site...... It just so happens that your father was the first person to find the deceased at the Sky Blue construction site, haven't you figured it out yet? Xiao Yi continued.

"No...... No...... It is impossible for him to see the murderer killing, and if he does, the murderer will not let him go, unless ......" Shangren suddenly thought of something, his face full of disbelief.

"That's right, that's it, the murderer knows your father, to be precise, he knows you, so he didn't kill Shang Wu at that time, and he also needs a person to report the crime to guide the police into the trap he set, unfortunately, your casual words caused him to step into the trap first. In order to prevent him from attracting the attention of the police, he had to be killed. Xiao Yi said with a smile on the corner of his mouth.
