It has been a whole day since Fu Nuan called the academic affairs office to inquire about the boys who had been suspended or dropped out of school in the past two or three months.

Just when she thought that this clue would sink into the sea, she received a phone call from the academic affairs office.

"Professor Fu, we have checked the records of suspension and withdrawal procedures in the past two or three months, and there is only one case."

Fu warm a listen, the flame of hope in the heart immediately ignited.

There is only one case in which exclusion is not necessary.

"Can you find out his contact information? I want to see him. "

"I'm afraid You can't see him. The boy who was suspended from school was named Sun Xiang. Not long after his suspension, his parents went to the school to cancel his school status because He committed suicide. "

Suicide?

Fu Nuan frowned at the news.

Finally, some clues are broken? Cheng Xin didn't think it was the man who killed her.

So who would it be?

Why did he drop out of school and why did he choose to commit suicide? Is it related to breaking up with Cheng Xin?

All this seems to have no answer

"But he has a brother who is a graduate student. If you want to know something about Sun Xiang, you can ask him. "

"I see. Thank you."

After hanging up, the academic affairs office sent her the phone number and dormitory number.

Sun Xiang's brother, Sun Fei, is a graduate student in chemistry department.

Seeing this dormitory number, Fu Nuan felt familiar for no reason. He seemed to have seen or seen similar numbers.

It was not until she got to the bottom of the dormitory that she understood why she was so familiar.

Sun Fei's dormitory is in the same building as the dormitory where Lin Ke was injured by a flowerpot. More coincidentally, it is on the upper floor of the diagonal building.

Fu Nuan knocked on the door with a little doubt. After a while, he heard footsteps coming from inside, getting closer and closer.

The door opened, and a slightly delicate face appeared in front of her.

Sun Fei was at a loss when he saw her.

"Who are you looking for, please?"

Are you Sun Fei? Hello, my name is Fu Nuan. I'm a professor in the Chinese department. "

Sun Fei thought for a moment, nodded and said, "Oh It seems that I have some impression. Professor Fu, are you looking for me

"Is it convenient for you to talk now? I want to know something about your brother Sun Xiang. "

Hearing the name "Sun Xiang", Sun Fei's eyes darkened.

"Xiao Xiang has passed away. What do you want to know?"

"Let's talk somewhere else?"

Sun Fei didn't object. He went back to his room and changed his clothes. He went downstairs with Fu Nuan. They came to a water bar near the dormitory building.

"I know it may hurt you to mention your brother now, but there is something I want to confirm with you."

"I understand, you ask. As long as I know, I will not hide it. "

Sun Fei's delicate face showed a touch of sadness, quietly looking at Fu Nuan, waiting for her question.

"Do you know much about Sun Xiang? What would you tell him, for example? "

"We have a very good relationship, he will tell me anything on his mind for the first time. But One day, a month before he left school, he became sensitive and depressed. In the face of my inquiry, he also refused to say, so I didn't know what happened to him during that time. I thought it was just that the mood was not high at a certain stage, and it would be better after some time. But he didn't expect that later he chose to leave school, and finally

Sun Fei pursed his lips, and his eyes turned red.

Fu Nuan did not continue to ask, but waited in silence for a while until he recovered.

"Sorry, I'm a little excited."

Sun Fei smiles with embarrassment.

"Life can't be reborn, please stop mourning."

It can be seen that Sun Fei and his brother really have a good relationship, otherwise a seven foot man would not easily shed tears in front of others.

"Did Sun Xiang ever tell you that he talked about a girlfriend in college?"

"Yes. I hear it's a pretty girl, but I haven't seen it yet. He had said that he would bring the girl to see me, but he didn't expect that... "

"The girl died."

Fu Nuan throws out this "heavy bomb" and wants to observe Sun Fei's reaction.

"Dead?"

Sun Fei was stunned and sighed: "what's going on?"

Seeing that he didn't look like pretending, Fu Nuan continued: "you should have heard of the famous net red Cheng Xin who fell from the building not long ago? In fact, the girlfriend Sun Xiang talked about is her. "

Sun Fei changed from Zheng Chong to surprise and asked, "you mean Xiao Xiang's girlfriend, the girl who fell from the building?"

Fu Nuan nodded and said, "as far as I know, your brother used to associate with her, but later broke up for some reason. Do you think it is possible that your brother can't stand the stimulation of breaking up, so he chooses to commit suicide?""If so That makes sense

Sun Fei suddenly realized with some sadness.

"It's no wonder that he behaved strangely before he retired from school. If it's because of emotional problems, it's not hard to explain. It's just why he's so stupid... "

"You don't hate her?"

This "she" refers to Cheng Xin.

Sun Fei shook his head and said, "it's Xiao Xiang who can't think of it for a while. No one is to blame for his death. Even if I really want to blame, I should be the elder brother. I didn't realize the reason why he was abnormal, so I comforted him in time... "

In fact, Fu Nuan didn't think of a possibility before he came. Sun Fei attributed Sun Xiang's death to Cheng Xin's betrayal. In order to avenge his younger brother, he killed Cheng Xin and, in the name of "final judgment", let people believe that it was the fulfillment of the curse.

But after the conversation, her suspicion of Sun Fei was reduced a lot.

He showed that he did not know Cheng Xin was Sun Xiang's girlfriend. He didn't seem to pretend at all.

As for him and Sun Xiang, it is obvious that they have a good relationship.

"Professor Fu came to see me today. Does he still suspect that I have something to do with the case?"

Fu Nuan didn't expect that Sun Fei would suddenly ask this question, and his words stopped for a moment.

"I won't do that."

Sun Fei said with a faint smile, "Xiao Xiang is no longer here. My parents are only left with me. I'm not going to take revenge on anyone at the risk of losing another son. What's more, before you came to me, I did not even know that Cheng Xin was my brother's ex girlfriend. "

Fu Nuan nodded. Although judging by intuition, she felt that Sun Fei was not the murderer she was looking for.

But if it is neither Sun Xiang nor Sun Fei, then who will be there?

Cheng Xin's interpersonal relationship is very complicated. There are many girls who dislike her or even hate her. The intercourse between the opposite sex is even more

Fu Nuan has a headache. If Sun Fei and Sun Xiang are in the wrong direction, it will be more and more difficult to continue to investigate, because there are too many motivated people.

"Does Professor Fu have any other questions?"

Sun Fei looked at his mobile phone and said, "I have an experimental class in 20 minutes. It's almost time to go."

"You go."

Fu Nuan said with a polite smile, "it's a waste of your time. I'm sorry about Sun Xiang... "

Sun Fei left Fu Nuan a faint smile and left the water bar.

Every time they think they find clues, they are rejected one by one. Who is behind the "final trial"?

No matter who he was, Fu Nuan made up his mind to find out the man hiding in the depths!
