Rong Yu felt the woman in front of him tremble, and tightened his grip on her. He held Fu Nuan's shoulders and turned her towards him, his eyes filled with worry as he stared intently at her face.

"Are you all right?"

Fu Nuan slowed down for a few seconds and then avoided the man's gaze. He slowly shook his head and noticed the label that had just been opened.

Rong Yu followed her gaze and saw that other than the name of the recipient, no other information was left behind.

"It must be that the teacher on duty at the administration office only saw my name and sent the courier directly to the office."

"Then ask him again and see if he knows who sent this."

Rong Yu had already realized the seriousness of the situation, and the expression on his face grew heavier.

"Yes."

Fu Nuan nodded, he picked up the landline phone and called the duty station.

"On duty teacher, I am Fu Nuan. I want to ask, do you know who delivered the courier to me?"

The teacher on duty hesitated for two seconds, then replied:

"Ugh …" It was a man wearing a mask and a black hoodie. "What's wrong?"

Fu Nuan: "Oh, I'm fine, I just don't know who sent it, so I came to ask, and I thank you."

After saying that, she slowly hung up the phone. However, she suddenly thought of something in her mind, and raised her eyes to meet Rong Yu's dark gaze.

"This is extremely similar to Yao Shujia's experience, it definitely isn't some sort of coincidence. Could it be that that person knew that I was investigating this matter, so he used this intentionally … to intimidate me? "

With that, Fu Nuan looked at the box that reeked of blood once again. His eyes no longer held any fear, instead, it was filled with determination.

"Who else knows about this?"

Fu Nuan shook his head, "Only Yao Shujia and I. However … I just got the surveillance tape from the Administration Department, and they found out about it so quickly? "

Hearing that, Rong Yu's expression became somewhat complicated. After a short moment of silence, he said in a deep voice, "Call your students out for an interview, maybe you guys have missed some clues."

In the evening, after the evening self-study time had ended, Yao Shujia walked into the school's cafe and saw the person waiting for her.

"Teacher Fu Nuan."

"Sit down."

Seeing Yao Shujia walking over with his backpack, Fu Nuan looked at Rong Yu who was sitting beside him, and introduced him to the students: "This is the department's Director Rong, I've already told him about you, and he helped us investigate this matter, but there are some details that we still need you to recall."

After Fu Nuan finished speaking, he glanced at the man beside him and handed the remaining questions to him.

"Good day, Director Rong."

Hearing Fu Nuan's introduction, Yao Shujia nodded his head in greeting towards the Prof. Rong, but then subconsciously looked at Fu Nuan again, his gaze sweeping back and forth between the two.

Rong Yu slightly nodded, and after a light cough, a clear and cold voice resounded:

"Think about it, have you ever had any contact with animals before? Or have you seen something about animals? "

Rong Yu had some guesses about this matter, in his opinion, using a dead animal to threaten people was really forced, there must be some connection.

After hearing the question, Yao Shujia frowned as he thought of something and slowly spoke:

"I worked as a volunteer for a period of time in the animal shelter outside the school. But in other words, going once a month to take care of those roaming animals can be considered an extracurricular activity. "

"Did anything happen there?"

Yao Shujia frowned, after thinking about it, there was nothing strange, but -

"I remember once seeing some boys passing by outside the shop. One of the boys was poking a small dog that had just been taken in at the door with a branch, and he almost blinded it. "

Hearing that, Rong Yu's expression became even more solemn, and asked with a low voice: "Almost?"

Yao Shujia nodded, "I went out to stop them later, so the dog was not injured. But that boy with the tree branch has gloomy eyes, and his gaze towards others is a little scary. "

Rong Yu did not ask anymore, and Fu Nuan understood the meaning behind his words.

Could it be that the person was targeting her not because she had a grudge with Yao Shujia, but because … For all who care about animals.

Fu Nuan also had a guess in her heart, if that boy was the culprit behind this incident, then she had reason to suspect that man.

As she thought about it, she blurted out, "Savage tendencies?"

Today, this kind of psychological topic was quite common on campus, and the higher education departments repeatedly reminded teachers to pay attention to it. Fu Nuan had read books on this subject before, so he was a little knowledgeable about it.

Rong Yu nodded slightly. Fu Nuan's way of thinking coincided with his. He glanced at the girl seated opposite him and asked again: "Do you still remember the boy's appearance?"
