Hitomi, who finally made a discovery, had a joy on his face that he hadn't seen for many days.

...... of Beiyang University

Si Nan, who was sitting on the chair and closed his eyes to recuperate, suddenly opened his eyes.

I seem to have grasped some important clue in my head.

She sat up quickly and pulled out a map that circled all the places where the bodies were dumped.

In the end, it was found that no matter how far away the body was dumped, all the places around it were Beiyang University.

What is the special significance of this?

What is Li Yuan implying about?

Why did he go farther away, but in the end he wanted to return to the vicinity of Beiyang University to throw his body?

Is he reminding this person?

Or rather, who is it threatening?

"Ning Xi."

While she was thinking, Si Nan was pulled back to her thoughts by this call, and she turned her head to look over.

It was the policewoman in the reception hall who sent her a letter last time.

"Is there something wrong?" Si Nan asked.

The policewoman placed an envelope on her desk as she did last time:

"Someone has sent you another letter."

Looking at the blank space on the envelope, the policewoman murmured with some confusion:

"Since it's a letter, why don't you even write the address, and you don't even put a postage stamp, and it was the same last time."

Xiao Qi next to him quickly realized that something was wrong, and hurriedly asked:

"What does the messenger look like?"

The policewoman touched her chin and thought for a moment, then replied:

"Wearing the postman's clothes, with a mouth, and coughing twice from time to time, it should be a cold."

Si Nan got up from his seat and asked:

"How long has the messenger been gone?"

Hesitantly looked at Si Nan and Xiaoqi, and the policewoman also realized that something was wrong, and said:

"It took less than ten minutes to walk."

The moment he got the reply, Si Nan looked at Xiao Qi:

"Xiaoqi, go chase people."

"Okay!"

Putting on his coat, Xiao Qi gathered other police officers to chase people while running.

Si Nan picked up the envelope from the table and opened it directly.

There were no letters and no photographs.

Rather, it's a very small USB stick.

Plugging the USB flash drive into his computer, Si Nan found that there was only one video file inside.

And the content of the video is the video she uploaded to the Internet seven years ago to record the rape of Liao Qi.

After watching the video several times, she finally realized that something was wrong in the video.

In the last two minutes of the video, Liao Yin's eyes were looking in the wrong direction.

From that angle, it was as if she had discovered the photographer.

But he didn't choose to call for help.

This is...... Why?

Is there a loss of hope, or is it a protection ......

Protection?

She was stunned when this idea came out of Si Nan's mind.

At the scene, in addition to the five boys who violated Liao Yin, only Yao Siqi was left hiding in the corner and secretly taking videos.

What would have happened if Liao Yin had asked Yao Siqi for help at that time?

Thinking in the worst direction, it is possible that Yao Siqi will not be able to escape that night.

Could it be that Liao Yin thought of this at that time and didn't ask Yao Siqi for help, right?

Xiao Slag heard the guess in Si Nan's heart.

Although I don't think it's very likely, it's possible.

So Liao Yin, this girl is too kind, right......

While experiencing such a thing as being violated, he can still think about others.

The little scum couldn't figure it out.

But in the end, it was concluded that humans are really complex creatures.

Si Nan suddenly realized the message that Li Yuan wanted to convey to her.

The last person he had to solve was Yao Siqi.

"Little scum, where is Yao Siqi now?"

After checking the relevant information, Xiaojie replied:

[After graduating from university, Yao Siqi stayed at Beiyang University as a teacher. 】
