I am Detective Wu Nan

Mohai City, Pudong Guanjiang Garden Community.

July 13th.

Nine o'clock in the evening.

A shrill scream cut through the long night, and the whole community was awakened.

Twenty minutes later.

Five or six police cars rushed and stopped downstairs. The city's criminal police captain Zhao Chenglong led more than a dozen public security officers to rush upstairs and came directly to the door of Room 602. The door had been knocked open, and the hostess of the house was lying in a pool of blood.

The deceased was stabbed several times, with the fatal wound in the neck, and blood was flowing all over the floor.

This is a homicide!

There were a large number of onlookers at the door, all of whom were neighbors of the deceased. After questioning, Zhao Chenglong learned that the deceased, Zhang Xia, was 42 years old this year. She had been divorced from her ex-husband for many years and had been living alone. She had a 20-year-old daughter who was in college.

……

Room 601, in a small, dirty and messy bedroom.

Wu Nan, who was only nine years old, was typing calmly on the keyboard, wearing headphones and playing music loudly! As a former criminal genius and a time traveler, Wu Nan swore before he lost consciousness after being struck by lightning in his previous life that he would be a good person in his next life!

But he couldn't control himself!

Only ten days after he traveled through time, his old problem came back!

Click! Click!

The sound of keys opening the door came from the front door, and the door was pushed open violently. The heroic policewoman walked quickly, her eyes swept across the living room, and then she quickly came to the door of the small bedroom and pushed it open vigorously.

Wu Xinyan saw her brother typing calmly on the computer, and she was relieved at first, and then she was furious!

This stinky boy is too careless!

After falling into the water and being rescued ten days ago, he looked confused and calm!

After that, he seemed to have become a different person!

There was no surprise at all. Wu Xinyan suspected that her brother had water in his brain!

"Play, play, play. You only know how to play games. There is such a big thing happening outside, and you are still playing games.……"Wu Xinyan stepped forward and took off Wu Nan's headphones. At this moment, Wu Nan hit the lock screen key on the keyboard, and the computer screen was locked. A password was required to unlock it.

"Hey? Sister, why are you back? Aren't you working overtime today?"Wu Nan turned his head to look at his sister, then tilted his head to look outside,"What's the noise outside?"

"Didn't you hear the screams?"Wu Xinyan frowned and asked. She had just questioned the neighbors upstairs and downstairs, but they all heard it.

""I heard it." Wu Nan said calmly,"And then?"

Wu Xinyan was choked. She heard that Wu Nan was still playing games calmly without any curiosity. He must be crazy!

"There was a murder next door, the victim was Aunt Zhang……"Wu Xinyan said, looking unhappy. She didn't expect that the murder would happen right next door to her house!

The deceased was her neighbor!

Although Wu Xinyan and her brother had only moved here for half a year, and the relationship between the neighbors was average, they were still acquaintances after all. They would greet each other when they met in the corridor!

Unexpectedly, the person was gone just like that!

"Aunt Zhang, oh……"Wu Nan is still very calm

"Oh, you big head!" Wu Xinyan raised her hand and patted Wu Nan's head,"Have you grown up? Aunt Zhang had an accident.……"Wu Xinyan couldn't continue

"well……"Wu Nan sighed.

He didn't know how to react. It was just a death, and he was just an acquaintance. It wasn't that he was cold, but he had been through too much and had long since become indifferent.

""Xiao Wu, what are you doing?" A voice called out from outside the gate.

"Captain Zhao, here I come!……"Wu Xinyan turned around and replied, and then gave Wu Nan a series of instructions,"Xiao Nan, remember to lock the door and don't walk around. I won't be back all night. Be careful of bad guys. If someone knocks on the door, don't open it no matter who it is."……"

""Yes, yes, I understand, sister, stop nagging." Wu Nan held his eyes and said

"Also, play less games, are you going to hurt your eyes? You can see 400 degrees at such a young age.……"Wu Xinyan was scolding him when she suddenly seemed to understand something. She looked at the locked computer screen and then looked at Wu Nan with suspicion,"Xiao Nan, what were you playing just now?"

"Just play some web games."Wu Nan said

"Why is the screen locked when playing web games? Are you afraid that I might see it?"

"It's just a habit. Sister, don't ask me. Aren't you busy? Why don't you go out? It's time to urge you again."

"Xiaonan, you……"Wu Xinyan's eyes became more suspicious, and she squinted at her brother, her face becoming worse. Out of professional habit and the insight of a criminal police officer, she knew that her brother must have done something bad!

Wu Nan finally got nervous. If his sister knew that he was writing a Trojan horse program, according to his sister's temper, she would definitely take him to the criminal police team for ideological education, right?

"Are you watching porn?" Wu Xinyan finally said her guess.

""Huh?" Wu Nan's expression froze.

Shit!

Misunderstanding!

That's not it!

"You naughty kid! You are so young, but you don’t learn well! No wonder you don’t pay attention to what’s happening outside! You are really focused!"Wu Xinyan slapped Wu Nan on the back of his head again and wrote it down.

"Xiao Wu, come here quickly……"There was another shout from outside the door

""Captain is here!" Wu Xinyan quickly turned around and responded, and then said to Wu Nan:"I'll deal with you when I come back!"

After Wu Xinyan finished speaking, she ran out quickly.

Wu Nan's face was still frozen!

Bang!

The sound of the door closing heavily came.

"No, sister, listen to me, I didn't watch any porn, I, I... I'm only nine years old...……"Wu Nan chased him to the living room and stopped, with a look of being screwed!

Now the yellow mud fell into the crotch, it was shit if not shit!

The browser history proved to be useless because it could be deleted!

……

In the corridor on the sixth floor.

The cordon has been set up, and the criminal police are conducting on-site investigations and collecting evidence. There is one thing to be thankful for, that is, although the door was kicked open by the neighbor who heard the scream, the scene was not damaged. The body can be seen standing at the door, so no one dares to go in.

Wu Xinyan came out, put on white gloves, and entered Room 602.

Criminal police captain Zhao Chenglong stood at the door and directed the scene.

Creak!

The door of Room 602 opened again. Wu Nan walked out, looked around, and then stood outside the cordon to look inside. The body had not been covered with a white cloth because the on-site forensic doctor was conducting an initial autopsy to determine the detailed time of death of the deceased.

Blood was all over the floor.

Standing outside the cordon outside the door, you can see that Wu Nan is looking at him calmly.

""Xiao Nan, why did you come out? Go back!" A young man with a flat head said to Wu Nan, and stretched out his hand to block Wu Nan's eyes.

The man was wearing a security uniform and his name was Yue Gang. He was one of the security guards at the post downstairs. He was just one of the many people who came to watch the excitement outside the cordon.

Although the criminal police on the scene repeatedly warned not to watch, it was completely useless. They could only keep the onlookers away. The purpose of the cordon was just like that.

"It's okay!" Wu Nan slapped Yue Gang's hand away.

Thump, thump!

A criminal police officer trotted up from downstairs, and the others made way. The criminal police officer ran to the captain Zhao Chenglong and said quickly in a low voice:"Captain, we checked the surveillance downstairs. In the past hour, no one has left the building through the downstairs gate."

"Captain." Another voice came from inside the house,"The window has not been moved, there are no signs of climbing, and there is a guardrail outside the window."

"Secret room murder"

"Isn't it? I've heard of this kind of thing, but I've never seen it."

Security guard Yue Gang whispered to Uncle Wang downstairs.

"How can this be considered a murder in a closed room?" Wu Nan couldn't help but speak, adjusting his glasses,"It was just an acquaintance who committed the crime, and the murderer is now in this building."

"It is very likely that the crime was committed by an acquaintance. Investigate Zhang Xia's neighborhood relations."Just as Wu Nan finished speaking, Captain Zhao Chenglong said this to his deputy captain Sun Meng.

Then he raised his head and looked at Wu Nan.

"Whose naughty child is this? Why don't you take him away quickly?" Zhao Chenglong yelled.
