This left a particularly deep impression on everyone.

"The family compound has a special register for package receipts. We checked the date and signature and confirmed that the package was received on the day of the incident, at 7:30 pm."

At this point, Captain Liu added, "We also visited the area near the Tan family some time ago, and some comrades who live nearby reported this to us."

"On the day Secretary Tan died, he saw him and a man heading towards the river."

"It was already dark at that time, and the light was dim. He only saw the other person's blurry back."

This person worked at a nearby steel mill. Calculating the time, it would have been around 5:30.

That time was the time when the gate guards were changing shifts.

Given the distance between the Tan and Xu families, even if Deputy Minister Xu pedaled his bicycle to produce sparks, it would be difficult for him to kill someone and then rush back.

"Also, according to that person, the suspect is not very tall and is thin. This doesn't match the body type of Deputy Minister Xu."

Are you thin?

After Jiang Si understood the situation, she had a rough idea in her mind.

Seeing her relaxed expression, Fourth Uncle Huo asked, "What are you going to do next?"

According to regulations, they can only detain Xu Bingkun for a maximum of seven days. Once the seven days are up, if there is no evidence, they have to release him.

Fourth Uncle is a family member, so Jiang Si did not hide it and waited for others to follow.

She said directly: "Rules are dead, but people are alive. Now that we have confirmed that he has problems, we must not let him go."

That's the logic, but the problem is that they have no evidence.

"It's not like there's no evidence. The batch of steel bars that were shipped in today are still there."

"Didn't you personally inspect it and say there was nothing wrong with that batch of steel bars?"

"It was fine before, but I won't talk about whether it's a problem now."

"You mean..." Fourth Uncle Huo instantly understood what she meant.

"That's right." Jiang Si admitted it straightforwardly.

She already knew that he had a problem, she just did it for him, what he wanted to do but she didn't.

After all, anti-blackness requires evidence.

To deal with people like this, all you need is a list.

Of course, this is the worst-case scenario.

If possible, Jiang Si still hopes to find conclusive evidence within seven days.

However, she felt that it should be soon.

Thinking about this, Jiang Si didn't stay any longer.

After talking to her fourth uncle for a few more words, she started the next step according to her original plan.

After coming out of the Municipal Public Security Bureau, Jiang Si went directly to the courtyard where Chi Heng was.

Today is the weekend, he should be at home.

Knocked on the door.

Soon a response came from inside, "Who is it?"

It’s Uncle Da’s voice.

The door opened, and seeing Jiang Si, Uncle Da smiled, "Miss Jiang, why are you here? Please come in."

Jiang Si said, "Uncle Da, is Chi Heng home? I have something to ask him."

"Yes, yes, you've come just in time. We were just about to have lunch."

Uncle Da hurriedly invited everyone in and said to a young man in the courtyard, "Miss Jiang is here, go get some more bowls and chopsticks."

The man hesitated.

His eyes subconsciously glanced towards the main hall.
