He actually didn't have any impression of this matter, but when he saw Liu Xiang's information …

His eyes lit up.

"The clerk at the front desk said someone came to ask where Liu's grave was buried with his ID card."

Xiao He was taken aback. After a moment of thought, he said:

"That's weird, isn't it? His own son actually doesn't know where he's buried."

"That's right."

At the beginning of the meeting, Xiao He began by describing the circumstances of each victim, as well as the relationship between Liu Xiang and the tomb owner, Liu Nianqi.

Then, he analyzed the evidence he had found on the scene today one by one. According to the judgement given by Forensic Medicine, as well as the reaction at the front desk, he determined that each head had been transported to the scene the night before. The exact time was still unknown, so he didn't know if there were any witnesses that night. Furthermore, the corpses below the head had not been found, so it was impossible to determine the exact time of death.

Then, Jiang Han began to express his point of view. He believed that since it was placed on Liu Changqi's grave, then this must be related to the father and son duo. As for what the relationship was, no one knew.

At this time, Xiao He added:

"I agree with Jiang Han's point of view. Captain Peng and I have already seen the case file regarding Liu Nianqi's death. Apart from the forensic autopsy report, there were no records on it. Therefore, we have decided to reinvestigate the death of Liu Nianqi. "

"Are you saying we have to restart an old case before we investigate this one?" Ning Ruonan asked.

It had been two years, she thought, and there was not enough evidence. There was only one autopsy report in the file. A case like this could only be investigated from the beginning.

"Yes." Xiao He nodded.

"Investigating what Liu Nianqi said, this person is a middle school teacher, his social relations should not be complicated, but of course, this needs further investigation and conclusion. For the time being, it can be divided into two parts: a school visit and a visit near home. "

"Jiang Han and I will visit the school. Squadron Peng and Ronan will go to Mansion 3, 404, 26 Copper Lake Road to investigate the situation at Liu's house. "

"I don't know if there are still people in his house, but you can visit his neighbors to find out more about the situation." Xiao He sighed as he looked at the information on the father and son pair on the table.

"Others, check out the suspicious vehicles and personnel from the surveillance footage on the main road around the cemetery."

After the tasks were assigned, everyone split up and moved out.

The next day, Xiao He and Jiang Han did not drive the car that was usually used for missions. Instead, they changed into casual clothes.

This made Jiang Han have a whole new level of respect for him.

"Since when did you know how to take off your thousand-year-old clothes and mess with yourself?"

Xiao He rolled his eyes and did not refute:

"Come, let's go back and see teacher."

"Looking at teacher?" Jiang Han was greatly taken aback.

"What is it?"

"Go to Mausoleum of Books's Third High School to see your teacher?"

"That's my alma mater. Is that weird?" Xiao He cast a sidelong glance at him.

Jiang Han didn't know whether to laugh or cry.

"That's true. I'm from the famous No. 3 High School. I'm the second brother next door to you, Jianxin Senior High School. I've been ceded by senior."

As he spoke, he extended his hand towards Xiao He with a coy smile.

Xiao He shook hands with him.

I just didn't see his expression.

Thus, Xiao He drove his car and brought Jiang Han to Wanning Street.

It was the most common way to go to school at that time.

Who knows where Ruonan went to high school.

Just as he was thinking, Jiang Han seemed to be able to see through his thoughts.

"Speaking of which, you definitely don't know that Ruonan is a level older than me. Their class was the only class on the same floor as the second year of high school. You can always see her in the hallway when you go to the toilet in the classroom. "

That tone was clearly used to make Xiao He feel envious, jealous, and resentful towards him. However, he did not seem to have succeeded.

The child wouldn't be jealous of anyone unless they had one. He didn't.

And so he gave a more childish response

"What's there to brag about? Captain Peng is still my senior at the police academy." "Hrmph."

The entire process of their bickering was skipped here.

Finally, Jiang Han put the question back on track.

"Since you are a student of No. 3 High School, don't you have any impression of Liu Nianqi before?"

"There really isn't one. Even its name is unfamiliar. "There are a lot of teachers in No. 3 High School, and he teaches liberal arts. If I wasn't taught by him in my first year of high school, I really wouldn't have had the chance to meet him in my entire high school."

The car finally reached the south gate of No. 3 High School.

This was a provincial high school. The new location of the school was in the suburbs, and it took up a huge amount of space. Its size was equivalent to that of a relatively ordinary university.

Although he'd already spoken to Professor Tan beforehand, he still couldn't find the third year school, let alone his office.

After making some mistakes, they finally arrived at the sixth floor of the school building. The teachers' offices were located in the middle of several classrooms.

He found his desk and breathed a sigh of relief.

Luckily Professor Tan wasn't late. He'd had so many classes today, he finally had forty minutes to meet them all.

"What about Professor Tan?"

Xiao He looked at his watch. In this era, he was the only one who wore a watch on his wrist all day …

"He should still be in class. Let's wait for him."

As he spoke, he found an empty seat near his desk and sat down.

After about fifteen minutes, Tan Lingyun finally opened the office door.

Upon seeing his teacher, Xiao He was pleasantly surprised.

"It's been so long since you've come to see me. I wonder if you could pour me some water to drink." Professor Tan was the same. He liked to joke around.

Xiao He immediately stood up and helped him receive the stack of books.

"Teacher, you sure know how to drag things out for those guys, haha."

Professor Tan was in his late fifties or early sixties, with a tinge of white on his temples. It was hard to tell whether or not he'd been smeared with chalk dust, but he still looked healthy and healthy.

"Come on, do two. Let's see if you can still do it. Have you forgotten all about the math that I taught you?" As he spoke, he flipped through the tutorial book with a smile.

Seeing this, Xiao He hurriedly declined. How could he dare to embarrass himself in front of his teacher?

Jiang Han, who was watching from the side, was also gloating.

"This is?" Teacher Tan looked at Jiang Han.

"Oh, this is my colleague. Since he had nothing to do today, he came with me."

"Oh, so that's how it is. Young man's physique is quite good."

"I saw it from the window when you were in the corridor. Up to the sixth floor. "He really is a young man."

When Jiang Han heard this, he smiled happily. This was the first time he had been praised by someone else's teacher.

Xiao He and Professor Tan exchanged a few words, then pulled out the contents of the bag.

It was a box of ginseng. Professor Tan's wife had never been well.

"Teacher, this is for mistress."

"Child, every time you come... As he spoke, he sighed.
