The president changed his career to become a detective

Ni Ruonan panicked and said: "Not good! If the criminal is really not Lei Xuanming, then the three of them may not be the target of the arson.

Ni Ruonan took a breath and said, "Then there will be other students or victims in other dormitories."

Thinking of this, Ni Ruonan immediately picked up the phone.She wanted to tell her younger brother Ni Tengfei to tell his classmates to be careful.

But before the call was made, Leng Xuanang received a call.

Leng Xuanang immediately said to the phone: "Hello, what's the matter?"

The call was from Lei Xuanming's head teacher.

The head teacher was very nervous on the phone and said, "Mr. Leng, it's not good! It's on fire again!"

The students were all in class, but another fire broke out in the boys' dormitory, this time it was very serious, because the dormitory management had no time to put out the fire, so the flames had already burst out, and they all called the fire alarm.

Leng Xuanang immediately put down the phone, and quickly dragged Ni Ruonan to Hongqi University.

Leng Xuanang found out that the dormitory where the fire happened happened to be Lei Xuanming's dormitory.Ni Ruonan and Leng Xuanang looked at each other.

It was obvious that it was not Lei Xuanming who set the fire.

However, when Ni Ruonan said this idea, Leng Xuanang immediately grabbed Ni Ruonan's hand.

"Ruo Nan, I know you don't want to believe this result," Leng Xuanang seemed to say something bad, "but from what I see, the previous arsonist might be Lei Xuanming, and now Lei Xuanming's bedroom is on fire. Now, it might be Ni Tengfei and the three of them."

Hearing Leng Xuanang's words, Ni Ruonan was silent for a moment at first, then immediately shook off Leng Xuanang's arm, and said loudly: "What do you mean? Are you suspecting my brother of arson?"

Leng Xuanang smiled awkwardly and said nothing more.

But Ni Ruonan refused to let go, and grabbed Leng Xuanang's arm again, and said, "Tell me, do you think in your heart that the arsonist is my brother?"

"Ruo Nan—" Leng Xuanang didn't know how to explain.

Ni Ruonan was very angry, and continued: "To get revenge on Lei Xuanming, my younger brother burned down the house and the bedroom, so my younger brother also set fire to Lei Xuanming's bedroom, right?"

Leng Xuanang nodded, but soon Leng Xuanang smiled awkwardly and said: "I'm just guessing, and I have no evidence to prove that it was your brother who set the fire."

Ni Ruonan immediately pulled his face, looked at Leng Xuanang very unhappy, and said, "What are you talking about? My brother is in class. How could he sneak out and set a fire?"

At this time, all the students had already finished class and returned to the boys' dormitory.

Ni Tengfei and two friends, Wen Yan and Su Taining also returned to the entrance of the boys' dormitory.

At the door of the boys' dormitory, Ni Ruonan walked up immediately, and said to Ni Tengfei, "Tengfei, you have been in class just now, haven't you?"

The younger brother smiled a little embarrassedly, faltering his head and not speaking.

Wen Yan, who was standing next to him, smiled immediately, curled his lips, but still didn't say anything.

Su Taining laughed loudly, and said to Ni Ruonan: "Your brother is not that honest, he said he went to the bathroom halfway, and he came back after about half a class."

"Oh? What did Ni Tengfei do?" Ni Ruonan asked quickly.

Su Taining laughed and said, "This kid must be hiding in the bathroom and playing games."

After Su Taining finished speaking, he quickly ran away.

Ni Tengfei immediately chased him out, but before he had run a few steps, Ni Ruonan immediately rushed up and grabbed his arm.

Ni Ruonan was very serious, and said to his brother seriously: "Have you returned to the boys' dormitory?"

Ni Tengfei didn't understand what his sister was asking at first, but then Ni Tengfei immediately became very upset with his sister.

Ni Tengfei said: "Sister, you don't suspect that I set the fire in Lei Xuanming's bedroom?"

"Is it you?" Ni Ruonan asked.

Ni Tengfei became nervous, waved his hands vigorously, and said, "That's not me! Sister, do you doubt me? Are you still my own sister?"

When Ni Ruonan heard the phrase "my dear sister", she felt a "thump" in her heart.Indeed, Ni Ruonan is not the real sister of his younger brother Ni Tengfei.

Leng Xuanang has been standing by the side observing the every move of the three boys, it seems that they don't look like an arsonist in any way.

Although these three boys don't look very honest, they definitely won't kill people and set fire to them, right?

However, intuition and guesswork are useless.In the world of reasoning, what matters is evidence.There are a few more details.

But all the details indicated that it was impossible for these three boys to come out and set fire.

If it was Su Taining and Wen Yan who had been in class all the time, the suspicion could be ruled out, then Ni Tengfei came out alone and went to the bathroom for half a class, so the suspicion could be ruled out.

During this half of the class, suppose Ni Tengfei came to the boys' dormitory and set fire to it.

Then the entire teaching building should be monitored.And the door of the boys' dormitory is also monitored.I knew it when I passed the door of the boys' dormitory.

And it is visible from any direction to the back of the boys' dormitory.

So now just mobilize monitoring.

Leng Xuanang immediately told Ni Tengfei's head teacher, and asked Ni Tengfei's head teacher to help mobilize the monitoring.

Sure enough, after looking around the teaching building in the surveillance, Ni Tengfei didn't leave the teaching building during the whole class.Looks like he really went to the bathroom.

After mobilizing the surveillance in the teaching building and looking again, Ni Tengfei really went to the bathroom, and really stayed in the bathroom for half a class.

It seems that Ni Tengfei really went to play with his mobile phone.

So who set the fire?If it wasn't the three of them, who would it be?
Could it be that the three of them secretly called someone outside to set the fire?This possibility is also possible.

Thinking of this, Leng Xuanang immediately asked the three of them, and found out their phone numbers, whether there were any call records.But no one has.

Leng Xuanang was thinking, maybe after they made a phone call, they deleted the communication records.The phone can delete the call history, but the platform cannot delete it.

platform that can recover this data.

Leng Xuanang immediately made a few phone calls, and after about 10 minutes, he immediately received a WeChat message.

Leng Xuanang clicked on it and saw that WeChat was nothing else, but that he asked someone to check the call records of the three of them, who they had called and sent WeChat messages to he.

Leng Xuanang took a look, and the three of them had indeed never communicated with any suspicious person.They also didn't send out some messy WeChat messages.

It seems that the suspicion of the three of them can be ruled out.

But besides using communication, can other methods be used to tell others to set fire?This situation is also unavoidable.

So the three of them were excluded just now, and now they are in doubt again.

When Leng Xuanang was staring at the phone in a daze, Ni Ruonan immediately said to him: "What's wrong with you? Is there any problem?"

Leng Xuanang smiled wryly, shook his head, and did not speak.

Leng Xuanang didn't know what to say, what if he continued to doubt the three of them?Will Ni Ruonan be very angry?Does it feel like he doesn't trust her brother?

So Leng Xuanang simply didn't speak.

Looking at Leng Xuanang's expression, Ni Ruonan was not a fool, he could tell at a glance that there was a problem.

Ni Ruonan immediately looked at Leng Xuanang suspiciously and said, "What does your expression mean? You are still doubting my brother, right?"

Leng Xuanang shook his head vigorously and said: "I'm not suspicious, there's really no way to completely clear your brother of suspicion."

"You think my younger brother set the fire?" Ni Ruonan was very upset.

Leng Xuanang lowered his voice and said, "I think there may be two people who set the fire this time."

"Which two?" Ni Ruonan said with personal emotions.

Leng Xuanang's voice became a little trembling, and he said: "The person in your brother's bedroom set the fire, it might be Lei Xuanming, and the person in Lei Xuanming's bedroom set the fire, it's probably your brother."

Leng Xuanang was also asked too much, so he told the truth.He can say whatever is on his mind.

Ni Ruonan was very upset when he heard this, and immediately stared at Leng Xuanang and said loudly: "I don't know how your brain grows?"

Leng Xuanang didn't understand, looked at Ni Ruonan, and remained silent, mainly because he didn't dare to speak too much.

Ni Ruonan still stared at him and said, "How could my brother murder and set fire? What do you think my brother looks like murdering and setting fire?"

Leng Xuanang looked at Ni Ruonan with a very professional look, and said, "I'm not suspicious of your brother with personal feelings? I just think that your brother can't get rid of the suspicion."

"You mean to doubt my brother! Is it because my brother is fooling around?" Ni Ruonan was inexplicably angry.

Leng Xuanang quickly explained: "I'm very calm now, and I don't have any personal feelings when looking at this matter, and I'm analyzing the case."

After Ni Ruonan heard this, she still couldn't accept Leng Xuanang's words.

Ni Ruonan just felt that Leng Xuanang was suspicious of his younger brother's fire.

The two actually quarreled.

When the two of them were quarreling, suddenly, Ni Tengfei's head teacher ran over immediately.

The class teacher came in front of the two of them, and looked at them with a look of concealment.

Then the homeroom teacher lowered his voice and said to the two of them: "Mr. Leng, according to your order, we checked the surveillance cameras near the school. Sure enough, a stranger has entered the school these few days."

After hearing this, Leng Xuanang immediately walked over excitedly, looked at the class teacher seriously and said, "Really? What about this person?"

The head teacher immediately took a mobile phone and showed it to Leng Xuanang.

Leng Xuanang clicked on the monitoring screen and watched it seriously.

This person was wearing a set of black clothes, a hat, and a mask, and his face could not be seen at all.Even if you can see it, you don't know who it is.

Leng Xuanang looked and looked, but didn't recognize this person.

I only see a person on the surveillance screen, and I don’t know which direction the person is coming from. How can I judge where this person is?

To find such a person nearby is almost like looking for a needle in a haystack.

Ni Ruonan snatched the phone, glared at Leng Xuanang, and then began to look at the surveillance screen.

Ni Ruonan looked carefully and found that this person came from the side of the city center.

The side towards the city center is actually the leisure area outside.This side is the opposite.

In other words, this person can be ruled out as the person on the side of the leisure area.

Of course, the leisure area includes many restaurants, many Internet cafes, and some hotels and the like.

How did the murderer get out?
