Rong Yin's case came to an end, and Fu Nuan's attention returned to the case.
There are people who are skeptical, but there is no evidence to point to, is it the investigation direction is wrong, or a certain link has gone wrong, so that she has overlooked something
Before she knew it, she fell into deep thought again, and she muttered: "Curse the post, the flowerpot hurt Lin Ke, Cheng Xin who fell inexplicably, the otaku who thought she was cheated by Cheng Xin for money, Cheng Xin's ex-boyfriend, the ex-boyfriend's brother... "
There must be some connection between these people and the event, but what is it
People who have hatred with Cheng Xin, hate enough to kill her, among the currently known characters, the boy who thinks Cheng Xin cheated him for money, as well as Sun Xiang's brother, are all suspected.
It's just that there is no evidence at present, and Chen Dong did not hesitate to admit that he really hates Cheng Xin. If he is really a murderer, his psychological quality would be better and he knows how to bravado.
As for Sun Fei, what he said almost leaked, and even Fu Nuan felt that if he doubted him, a good brother who had lost his younger brother, he couldn't bear it.
"What is wrong..."
Rong Yu flicked her head lightly, recalling her mind of swimming.
"Professor Rong, my brain capacity is almost running out. You can help me think about what is going wrong?"
"Ok."
Rong Yu let out a nasal sound, but did not continue to speak.
Fu Nuan looked at him strangely and found that he was staring at her with meaningful eyes.
Generally speaking, such Professor Rong...
"Husband~ You are so smart, can you help me? Give some hints..."
Rong Yumei picked up slightly, and gestured her to pass.
She walked up to him and sat in his arms obediently.
He gently curled her hair with his fingers, and slowly said, "What do you care about most now?"
Fu Nuan thought for a while and replied, "The rooftop. How did the murderer avoid the sight of the security guard on duty and take the person onto the rooftop before throwing it down?"
"Sounds impossible, does it?"
Fu Nuan nodded. This is what she can't figure out the most.
"If the security is telling the truth, it is impossible. But if he lied..."
"You mean..."
Fu Nuan suddenly realized after such a call.
Perhaps the image of the uncle security guard was too honest and honest, and she never thought that he might be telling the truth.
Of course, it is not that he conspired with the murderer or shielded the murderer, but if he lied, he was not always there during the duty, and he was afraid of taking responsibility when he died, so he chose to conceal it. This possibility is not unavailable.
"Such a simple truth, why didn't I think of it!"
Fu Nuan rubbed her head with a little annoyance. People said that she was silly for three years, she almost doubled. Why did she still feel that her IQ was not enough
"simple?"
Rong Yu raised his eyebrows, and asked in a deep voice.
"No... I said something wrong! It's not easy at all, my husband is the best!"
Fu Nuan hurriedly tried to remedy it before Professor Rong became angry.
"Well, worship me as much as possible."
With such suspicions, Fu Nuan decided to talk to the uncle security guard the next day to see if he could ask anything.
…
The next day.
Fu Nuan arrived early at the teaching building where Cheng Xin fell. The security guard who was supposed to be on duty at the corridor leading to the rooftop was not there.
It stands to reason that he should have already arrived at this point.
Fu Nuan remembered that it was about this time when Cheng Xin fell down the building that day.
And at this time today, the security guard is not on the job, is it a coincidence, or it is his habit, every day.
And someone happened to grasp this, and while he was away, he dragged Cheng Xin to the rooftop after making Cheng Xin dizzy
If it is the same as she guessed, then this person must have premeditated, perhaps he knew the security guard, or he had been observing his actions for more than a few weeks.
Fu Nuan sat in the security guard's position and waited for people to come back. This wait was almost half an hour.
…
"Master, are you back?"
Fu Nuan saw the figure not far away, it was the security guard who took her to the rooftop that day.
Seeing Fu Nuan, an unnatural expression appeared on his face.
"You... Why are you here again? Didn't you see the rooftop the last time?"
Fu Nuan smiled and said, "I didn't come to see the rooftop, I came to see you."
When the security guard heard this, his face changed drastically. Could it be that his secret has been discovered
"Look for me? What do you want me for? I just went to the toilet and my stomach hurts."
"I've been here almost half an hour ago. Diarrhea, more than half an hour? How are your legs?"
Fu Nuan stared at the security guard's legs suspiciously. He was so guilty that he almost couldn't help telling everything.
"You work early to get up and go to bed late. I can understand you being lazy. But your superiors should not be as reasonable as I am. Just tell me if you will leave the duty position for more than half an hour at this time every day, I swear I won't tell your leader."
The security guard looked at her embarrassedly, wondering whether to believe what she said.
"If you leave your post without authorization once and leave your post several times without authorization, your processing results will not be much different, so if it is true, it doesn't matter if you admit it. On the contrary, what you said may be a great deal to the detection of Cheng Xin's case. s help."
"I… "
The uncle security hesitated again and again, and finally gritted his teeth and admitted.
"Ten minutes before that girl fell. I ran to be lazy as usual, but how did I know that something like this would happen? I was afraid that I would be found to be responsible, so I could only hide it, and return to my post when I was in chaos... I didn't mean it... Oh!"
After finally telling the truth, the uncle security also felt much better.
After listening to this, Fu Nuan frowned solemnly.
In this way, the previous guess is more likely.
"Does anyone know your habit?"
The uncle security guard thought for a while, moved his mouth but kept his mouth shut, and swallowed his words back.
"If you think of anything, please tell me. Otherwise, you may be counted as a cover-up murderer."
Fu Nuan continued to try to persuade and pry out the secret in his mouth.
"Hey... there is such a young man, he knows that I will go back to hide my laziness at this time every day. About a month ago, when I returned to my post and saw him sitting in my seat, I was shocked. He said he liked it. Be quiet, go up to the rooftop to get some air, and reading on it will make you more involved. I was worried that he would denounce me, so I agreed. Later I found out that this guy was pretty good, he would give me cover, and sometimes he would bring me Some food..."
Having said this, he stopped abruptly, and asked Fu Nuan in surprise, "You are not suspecting him? No... Impossible, the young man is gentle, he looks very sunny, and he can't kill."
Fu Nuan pursed his lips. He didn't look like a murderer, and he might not be a murderer. After all, murderers wouldn't write those big words on his face.
"what is his name?"
The uncle security shook his head and said, "I don't know..."
Under Fu Nuan's questioning gaze, he persisted.
"I really don't know, I didn't ask his name..."
"Uncle, I will give you..."
The sound stopped abruptly.
Fu Nuan heard the sound and turned to look at that person, she just met not long ago...
