I am Detective Wu Nan

"It's him! It could be him!" Wu Nan tapped the transcript twice, quickly stood up, ran to the door of the master bedroom, raised his hand and banged on the door,"Sister, come out, sister……"

Wu Xinyan had just fallen asleep when she was woken up again. Her head was buzzing with pain.

""Stupid kid, what are you doing? Is it time yet?" Wu Xinyan said angrily,"Shut up!"

"Sister, come out, I have something to tell you.……"

Bang, bang, bang!

Inside the house, Wu Xinyan turned over and held her head with a pillow.

Wu Nan gave up!

Wu Xinyan was too tired to come out, and even if she was asked to come out now, her brain was like a paste, and she probably wouldn't remember the reasoning process.

"My poor sister.……"Wu Nan sighed, turned around and looked at the scattered documents on the coffee table, but did not pick them up. Instead, he changed his mind and walked quickly towards his bedroom.

He came to the computer, sat down, and searched the water supply bureau network system.

Crack!

Wu Nan quickly typed on the keyboard, because the water supply bureau system really did not involve any privacy secrets. As long as Wu Nan did not modify the water use data, it should not be considered a crime, right?

Wu Nan successfully cracked the water supply bureau system.

Then he looked at his sin value, which did not increase, and he was fine!

"Guanjiang Garden……Unit 1……501……502……701……702……"Wu Nan checked and smiled. He checked the water usage of the four households upstairs and downstairs on July 13, the day of the crime. The results showed that Room 501 used a huge amount of water on that day...

Room 501, the resident downstairs from Wu Nan, was named"Wang Shengli"!

And this person was also Wu Nan's biggest suspect before!

……

Seven o'clock at night.

Boom, boom, boom!

"Sister, it's seven o'clock, get up!" Wu Nan knocked on the door and said

"Um... stop making noise... wake up……"Wu Xinyan's dazed response came from the bedroom.

Not long after.

Wu Xinyan walked out of the bedroom, rubbing her face. She was still wearing the clothes she wore when she came back. The clothes were full of wrinkles and her hair was messy. She was really a haggard beauty. The whole person looked terrible!

She didn't get enough sleep at all!

Wu Nan took the electric kettle to the wall, intending to boil water for instant noodles. Wu Xinyan walked to the sofa and sat down. She opened the briefcase, and her face changed immediately. She looked up and said,"Xiao Nan, did you touch my things?" Wu Nan deliberately let her find out, otherwise, Wu Nan could have tidied it up so that Wu Xinyan would not notice.

"Yes, sister, I read the file of Aunt Zhang's case a few days ago.……"Wu Nangang almost put the kettle down, turned around and said

"Who told you to move? You naughty kid, you messed it up! Why are you so disobedient!"Wu Xinyan was very annoyed. She had to write a report, but now the file was messed up. It would take her a long time to sort it out.

"Sister, I just want to help you!" Wu Nan laughed,"Calm down!"

"Help me? I'll be thankful if you don't cause me trouble!" Wu Xinyan's face was not good. As she spoke, her eyes turned red. It was not because she was emotional, but because she was under too much pressure.

The leaders of the municipal party committee personally supervised this case!

You know, Mohai City is a municipality directly under the central government! If the case cannot be solved within the deadline, I don't know how many people in the bureau will be punished!

""Sister, sister, don't cry!" Wu Nan immediately trotted to the sofa and held Wu Xinyan's hand.

Wu Xinyan shook her hand unappreciatively, sniffed and said,"Go away, don't make trouble for me!" As she said that, she took out the scattered documents from the bag, pursed her lips and sorted them out, tears falling!

She hadn't slept for two or three days to sort them out. She was so sleepy that she only slept for a few hours. She wanted to sort them out again, but the naughty children at home messed them up!

"Sister, don't cry, don't cry, I'm telling you, I know who the murderer is!"Wu Nan leaned closer to Wu Xinyan and said seriously

"Hmm?" Wu Xinyan turned her head to look at Wu Nan, sniffed hard, coughed, and asked in a clearer voice,"You know? What did you find? Xiaonan, I'm telling you, you can't say such things casually. Did you see something that day?"

"No, I came to this conclusion after analysis!" Wu Nanlian said,"In this file, you overlooked a very important issue!"

"what is the problem?"

"It is impossible for residents on the first floor to hear screams from the room on the sixth floor!"

"What kind of question is this? How can it be impossible? Xiaonan, please stop analyzing it here. I'm very tired. Please don't give me……"

"Sister, listen to me.……"

Half an hour later.

Woohoo!

A police car arrived downstairs of Unit 1 of Guanjiang Garden. Criminal police captain Zhao Chenglong, deputy captain Sun Meng and four others got out of the car and ran upstairs quickly. Just a dozen minutes ago, Zhao Chenglong received a call from criminal police Wu Xinyan in the team, saying that he had found a major clue and needed to report it.

Because it was not clear on the phone, Zhao Chenglong and his men hurried over.

The four ran all the way upstairs and knocked on the door of 601.

It was Wu Xinyan who opened the door.

"Captain, you are here.……"Wu Xinyan invited people into the house. She washed her face, but she still looked very haggard.

"Xiao Wu, didn't you sleep? You look so bad.……"Zhao Chenglong said

""I slept for a while." Wu Xinyan said, rubbing her face again.

The others turned their heads to look at the environment in the house. It was really dirty and messy. It was impossible to expect nine-year-old Wu Nan to clean the room, and Wu Xinyan had no time to take care of the house.

"It's not easy for Xiao Wu to take care of his brother alone!"Zhao Chenglong sighed.

"What's going on? Tell me now!" Deputy Captain Sun Meng said

"Ah... that's it...……"Wu Xinyan considered it,"Just now my brother said that on the day of the crime, if the scream of the victim came from the sixth floor, the residents on the first floor could not have heard it. But according to the records of the residents on the first floor, they heard it very clearly.……"

"Didn't we discuss this in this morning's meeting?" Zhao Chenglong said,"Whether it can be heard or not is uncertain. A woman's scream is about 70 decibels.……"

"Xiao Wu, what's wrong with you? Everyone is so busy, and your brother said something casually, and he called us all over! Comrade Wu Xinyan, are you stupid?"Sun Meng scolded

"No, Captain Sun, what else is that if the sound was not made by Zhang Xia?……"Wu Xinyan seemed to be unable to speak because she was in a very bad condition and felt dizzy!

""Okay, okay, what are you doing?" Sun Meng said impatiently.

"Hey!"Wu Nan, who was sitting on the sofa eating instant noodles, couldn't help but look up,"Hey, so-and-so, what are you doing? Why are you scolding my sister so harshly? Can't you talk nicely?……"

"Xiaonan!"Wu Xinyan called out immediately

"Comrade Xiao Wu, can you take care of your brother? This is not a game of house!" Sun Meng said louder.

"Okay, okay, Lao Sun! I know you are anxious, don't be so angry!"Zhao Chenggong made a smooth talk and looked at Wu Xinyan again,"Xiao Wu, please continue……"

"Then... since that's the case, let's assume that the scream didn't come from Zhang Xia, so……"

Wu Nan couldn't listen any more!

Wu Xinyan was not in a good condition to report.

"Slurp……"Wu Nan took another bite of instant noodles, wiped his mouth and stood up and said,"Sister, let me tell you!"

""Okay, Xiaonan, you tell me!" Wu Xinyan said immediately. She was shocked by Wu Nan's reasoning before, and she was convinced!

"What are you doing?! What on earth are you doing?!! Wu Xinyan! Why did you let your brother get involved in a murder case?! Huh? What on earth do you want to do?!"Sun Meng exploded directly, and he smashed the briefcase in his hand against the cabinet beside him with great force. I don't know if it was because he was used to slamming the table.

There happened to be a broken vase on the cabinet.

The vase shook a few times!

Bang!

It fell to the ground and shattered!
