When night fell, the whole sky turned black, and the entrance to the school, which was supposed to be lively, was empty at this time, and there was a ray of moonlight in the sky glowing red, like devil's glasses.

The style here is cold, even though it is summer, it makes people feel cold all over.

"Boss, why is it so cold here! It's so quiet, and the wind is scary. ”

"It's not the sound of the wind, it's Song Qian's soul confiding in us again, the red moon in the sky is her eyes, it's approaching us step by step, I can hear its footsteps, one step... Two steps, getting closer. Chen Dawei said slowly

"Team Chen, you know that Fang Yuan is cowardly and you still scare her." Zhou Qi said

"Boss, no, you see there's a light over there." Ma Jianchao said

Outside the fence at the entrance of the school, there are densely hung lights, there are red and green lights, and the flames are flickering and beating.

"Let's go, go over and have a look."

Chen Dawei looked at Fang Yuan and Zhou Qi standing still, he urged: "Why don't you leave, why are you standing?" ”

"Boss, someone patted my feet," Fang Yuan said

"Get out of the way, I see who's pretending to be a ghost, why is there no one?" Nobita said with an arrow step

Chen Dawei vaguely heard a person's cry for help, and his voice was hoarse, "Help... Help me"...

"Run, there's someone behind you."

Fang Yuan and Zhou Qi ran a few steps forward, and a sewer mouth was exposed, and the voice just now came from here.

Nobita went up and flucked the grass and saw a wooden stick moving up and down.

Nobita grabbed the wooden stick and pulled the person inside, this person Chen Dawei they had seen.

"Uncle, why are you, you scared me to death." Fang Yuan Road

"Water... water..."

A few of them hurriedly carried the doorman to the guard's room.

The doorman took a few sips of water and said slowly, "Thank you, if it weren't for you, I would have to spend the night in the sewers." ”

"Uncle, why are you there?"

"It's also my back, and I can fall into it if I light a lamp, I don't know which rabbit took the sewer manhole cover and ran away." Uncle Doorman said

Chen Dawei chuckled in his heart, and then asked, "Has the manhole cover been missing?" ”

"The manhole cover was still there some time ago."

"About a few days ago?"

"A week or so."

The time of a week or so coincided with the time of Song Qian's disappearance, it was not such a coincidence, Chen Dawei thought to himself.

"Uncle, why are there so many lights on the school wall?" Chen Dawei said

The doorman said: "The students in the school of lights hung it spontaneously, it is a custom to light an ever-bright lamp next to the coffin of the deceased, which is said to be used to guide the soul of the dead, what illuminates the way to the underworld and does not let the soul get lost. ”

"What age is this, and there are still people who are so superstitious, not to mention that there is no need to order so much." Fang Yuan Road

"Girl, don't talk nonsense, the deceased will be unhappy, this is all caused by the teachers and students in the school, and everyone is also kind." The doorman glanced at Fang Yuan and said.

Chen Dawei said: "I've also heard of the ever-bright lantern, shouldn't it be white?" ”

"Who said it wasn't, it's all colorful, has Song Qian's body been found? I heard that the murderer was Mr. Zhang, which is also terrifying. Uncle Doorman said

Chen Dawei shook his head, he had a guess in his heart, and his eyes suddenly swept to the wooden stick in the hand of the doorman, and there seemed to be blood stains on the wooden stick.

"Uncle, show me the stick in your hand?" Chen Dawei put on his gloves and took the stick.

Sure enough, there were blood stains on the sticks, and the blood stains had been handled, and they couldn't be seen if they didn't pay attention.

"Uncle, where are you going to go to the sewer?" Chen Dawei was skeptical

The doorman said: "This is not the lamp that people usually light on the top of their heads and at the end of their feet after death, but Song Qian doesn't even have a corpse, and everyone kindly hangs the lamp, I can't let the lamp go out." I used to light the lamp and who knew it would fall. ”

"Uncle, this stick may be a piece of evidence, we have to take it away, and I also ask you not to leave the city recently." Chen Dawei said

"Captain Chen, what do you mean, are you suspicious of me?" Uncle Doorman said

"Don't get excited, because this stick has your fingerprints on it, and you can suspect anyone until the case is solved." Chen Dawei said

"Go, go... Hurry up, just your way of handling the case, suspect this and suspect that, no wonder it's been a few days, and I can't even find a body, hurry up, I still have to rest. The doorman said angrily

Chen Dawei asked Zhou Qi and Fang Yuan to take the stick back to the police station for identification, focusing on extracting fingerprints and comparing them with Zhang Yuncong's fingerprints, he and Ma Jianchao tossed in the sewer all night and found nothing.

The results of the blood identification came out, the stick became a murder weapon, the blood stains on the stick were indeed Song Qian's, two fingerprints were extracted from the stick, one was the doorman's, and what was unexpected was that the other fingerprint was not Zhang Yuncong, and the case was at an impasse again.

"Boss, can Zhang Yuncong's suspicion be basically ruled out." Ma Jianchao said

"Not necessarily, it can only be said that the suspicion is small." Chen Dawei said

"If the murderer is really not him, he will be too wronged, you see that he is now scolded as a dog on the Internet, and some people say that they will kill him to eliminate harm for the people." Ma Jianchao said

"How did all this news get out?"

"Boss, these are all online self-media generations, there is such a big case, and the attention is so high, the news can't be blocked." Ma Jianchao said.

"Let's go, go to Zhang Yuncong's house, I still have something to ask him." Chen Dawei said

There were many reporters at the entrance of Zhang Yuncong's community, and the doorman at the door stopped them, and a policeman came over.

"Team Chen, you're here."

"How is Zhang Yuncong's family?"

"He's been sleeping in the house since he came back, and he hasn't gotten up until this point." The police said.

I don't know why, Chen Dawei has a bad premonition, maybe it is intuition, it is more than nine o'clock.

Chen Dawei knocked on the door for a long time, but there was no movement inside, and he slammed the door open. As soon as he entered, he was dumbfounded, and he saw Zhang Yuncong lying on the floor of the living room. Clothes and pants were casually thrown on the couch, and there were leftover half-dishes and two empty liquor bottles on the table.

Suddenly, he smelled a strange smell, the smell of gas.

"Gas! Dangerous! ”

Chen Dawei blocked Ma Jianchao and several other policemen who wanted to enter the door, covered his mouth and nose with his clothes, and immediately opened the window on the balcony.

There was a pot on the old-fashioned gas stove in the kitchen, and the fire was turned on but turned on. Chen Dawei held his breath and turned off the main gas switch, and opened the kitchen window again.

When he came to the living room, Zhang Yuncong, who was lying on the floor, had turned blue, there was no life, and the person was already dead.

"Captain Chen, are people still saved? Do you want to call 120? A policeman asked

Chen Dawei said, "Forget it, the corpses are already frozen, call Zhou Qi over, and notify Zhang Yuncong's family." ”

"Boss, Zhang Yuncong's daughter-in-law is remanded in the detention center, I'll go through the formalities immediately." Ma Jianchao was afraid, and he kept standing at the door

Chen Dawei nodded and motioned for Ma Jianchao to go, and then said to the police around him: "Block the scene, and no unrelated personnel are allowed to enter or leave." ”
