As a local policeman, is it appropriate for you to take over the job of a criminal policeman?

On the table, a 20-centimeter dagger caught Ye Lin's attention. He took out his gloves and picked it up gently.

Seeing Ye Lin pick up the dagger, Meng Xianmin's face suddenly became ugly, and he quickly explained: "I was just playing around, just cutting some fruit or something, I didn't do anything bad."

This is an imitation military dagger with a sharp blade. Influenced by the heroic movies of the Eagle Sauce, many people in Daxia have a special liking for this kind of military dagger, as if they will become superheroes if they get the dagger.

Ye Lin gestured lightly. With the sharpness of this dagger, it was enough to kill Zhang Liqin with one blow on the throat.

He put it to his nose and smelled it. It smelled of fruit and some unknown food, but no smell of blood.

Over there, Chief Li was already standing behind Meng Xianmin vigilantly. As long as Ye Lin noticed anything, he would immediately hold him down.

But the result still disappointed him. Ye Lin shook his head, "There is no smell of blood."

Meng Xianmin's expression relaxed, he took a deep breath, and said with a smile: "Comrade police, I really didn't do anything bad. I just bought one because I liked it."

"We will check whether it was done or not when we get back. You don't need to say so much." Chief Li interrupted him harshly. He originally thought that he could call it a day after catching the murderer, but he didn't expect that it was all in vain and he had to continue investigating.

Ye Lin looked around the house carefully and found nothing suspicious. He guessed that Meng Xianmin had felt guilty before because of this dagger.

Before leaving, Chief Li once again instructed him to take the gas cylinders and batteries out, otherwise he would have no way to escape if something happened.

After investigating Meng Xianmin, Ye Lin also said goodbye to Chief Li and went to the bureau. He didn't have any clues on his side, so he decided to see if there were any clues on the other side.

It was almost time to get off work before Sun Jinghua and Qi Shan came back. Judging from the expressions on their faces, they seemed to have found out something.

"Any findings?" Ye Lin asked.

"A little bit, but I don't know if it's useful." Xiao Sun said with a hint of fatigue.

"Then let's sit down and talk together."

Sun Jinghua found a seat, took out his little notebook and started talking.

"Captain Ye, we have sorted out the facts and found that there were 11 people in total who had disputes with the deceased Zhang Liqin, including 6 deliverymen, 3 couriers and 2 cleaners."

"First, there were two cleaners, both women in their 6s. They usually finish their work in the morning and leave in the afternoon. On the night of June 12, both of them stayed at home. There are family members who testified that there was no time for the crime. From the conversation, it seems that these two women don't seem like people who would dare to kill."

"Then there were three couriers. They were all at the delivery point counting the goods at night and had no time to kill anyone."

"We checked the delivery records of six delivery drivers on June 6 and found that they were all delivering food and did not have the time to commit the crime."

The more Ye Lin listened, the gloomier his expression became. Damn, you didn’t even have the time to commit the crime, and you’re telling me you have any clues.

Sun Jinghua also noticed that Ye Lin was a little impatient, and hurriedly said, "But when we asked them if they knew Meng Xianmin, they said they knew him, and that Meng Xianmin had once gone to Zhang Liqin's door with a knife and took photos."

Ye Lin's expression changed. There really was something wrong with this kid Meng Xianmin.

"Where are the photos?"

Sun Jinghua opened his phone and opened a photo. It was a selfie. Meng Xianmin was wearing the uniform of a certain regiment, with his helmet off. He was holding a dagger in his hand and standing in the corridor. Behind him was Zhang Liqin's door. He made a throat-cutting gesture with the corners of his mouth raised with pride, as if he had avenged himself.

Ye Lin recognized it at a glance. This dagger was exactly the same as the one he found in Meng Xianmin's house today.

“What day was this taken?”

"It was posted to their deliverymen's WeChat group at 6:12 pm on June 9. It should have been a selfie taken on the same day."

Ye Lin narrowed his eyes slightly. On the day of the crime, this guy actually went to Zhang Liqin's house with a dagger.

He looked at the photo carefully. Meng Xianmin in the photo was completely different from the timid look he had during the day. He had a bold look on his face and was grinning happily. It seemed as if he had let himself go.

But the blade of the dagger in his hand was very clean, without any trace of blood.

Ye Lin tapped his fingers lightly on the table. He was thinking about a question. If Meng Xianmin had killed him, then there would be no need to take a selfie to show off.

"Captain Ye, I know the murderer would never do this. But look at the chat records." Qi Shan took out her mobile phone, which contained several photos of the WeChat group chat records.

"Old Meng is so powerful."

"Old Meng is going to get rid of harm for the people."

"Knock on the door, don't stand outside. See if this woman will be so fierce again."

"Come on, start the live broadcast and show us."

A group of people left messages and flooded the screen under Meng Xianmin's photo, all of them were the kind who just wanted to watch the fun and make trouble.

Meng Xianmin was chatting proudly with others in the group at the beginning, but later his tone changed a bit.

"You're just talking nonsense, do you dare to knock on the door?"

"That's right, knock on the door, come on, and give our delivery guy some face."

"This dagger can't be made of plastic, are you trying to make fun of me?"

"With a gentle wave, the world becomes quiet. Do you dare? If you don't dare, I will do it."

No one knew what the people in the group were thinking, but they actually started to instigate Meng Xianmin.

Meng Xianmin couldn't stand it anymore and replied in the group:

"I don't dare? Even ghosts are afraid of me when I get angry."

His words immediately excited everyone in the group, and words like "Come on." "Let's do it." "Let's get started." filled the screen.

But later on, Meng Xianmin remained silent, so everyone stopped discussing the topic and started complaining about other weird customers.

No one knows what Meng Xianmin did later.

"Captain Ye, you see, I think Meng Xianmin was probably provoked by someone and couldn't help himself, so he took action." Sun Jinghua looked at Ye Lin with expectant eyes, hoping that Ye Lin would agree that what he said was right.

Ye Lin frowned. This Meng Xianmin was indeed beyond his expectations. He didn't mention this matter during the day.

Judging from the photos he posed for, this person must have a performative personality and hopes to gain people's recognition.

In this situation, it is indeed possible that someone committed murder in the heat of the moment.

Instigated by the people in the group, he knocked on the door and killed the man with a knife. Then, he was frightened by the scene in front of him and closed the door in panic without going in. This is consistent with the current case.

The only thing wrong was the knife. Ye Lin didn't smell any blood. With his nose enhanced by the system, he would definitely be able to smell blood if there was one, unless there was a second knife.
