"Yes, it's that someone was killed in the previous banquet restaurant, and the murderer escaped from the sewer, and then came out of this opening, so I ask if you see it!" Li Chaonan explained, looking at the old lady with eager eyes.

"I didn't see people, the night before yesterday I had a bad stomach and I came out of the toilet to hear the manhole cover, I thought someone was stealing the manhole cover, so I put it in the crack of the door to take a look, and it almost scared me to death!" The old lady was terrified as soon as she remembered what had happened that night.

"What do you see?" The three of them took a step forward in unison, staring at the old lady with blank eyes, and the frightened old lady took a step back.

"Ouch, let the three of you scare me, if it weren't for the fact that I thought I would have seen the three things from that night again in broad daylight!" The old lady patted her chest and gave the three of them a strange look.

"I'm sorry aunt, we're so excited!" Li Chaonan hurriedly apologized to the old lady. It's really urgent, can't you just say the key? Why do you like to sell when you talk!

"It's okay, I was scared away when I was lying on my stomach at the crack in the door, what do you think I saw?" The old lady pretended to look at the three of them.

"What?" The three of them craned their necks and looked at the old lady, obviously dying, but they had to cooperate with the old lady to satisfy each other's vanity.

"Mom, the three brains are flying in the air, and they are still talking, so scared that I crawled back to the house, I told this old man, and he also said that I was dazzled by sleep!" "Smack", the old lady slapped her hand and stared at the thief, so she didn't forget to complain about her old man.

"And then?" Liu Yang couldn't help it, if he didn't ask again, he might go somewhere.

"Then I went back to the house, I was scared to death, how dare I look at it again!" The old lady looked at Liu Yang with strange eyes, could it be that this is a fool, right? I'm so scared, I'm not going home, where can I go? Still asked later? If I look at it any further, there will be no follow-up.

"No, I asked you and you didn't come out to see it again!" Liu Yang asked anxiously.

"You're sick kid, aren't you? I'm crazy, I'll come out and have another look? The old lady glared at Liu Yang unceremoniously. If they are really sick, and they are not lightly ill, these three people can't be patients who escaped from a mental hospital, right? Thinking of this, the old lady took another step back and put her hand directly on the doorknob.

Zhang Qiqi and Li Chaonan have the black line in their heads, even if they are in a hurry, they can't ask such two questions, right?

"Thank you, auntie, if you have any more news, please feel free to contact us!" After Zhang started speaking, he wanted to give himself a mouthful, isn't this cursing the old lady to see the "ghost" again.

"A bunch of neurotics!" Sure enough, the old lady couldn't stand it anymore, so she scolded and closed the door. "Old man, why don't we call the police, these three people look like they are neurotics running out of a mental hospital!"

Li Chaonan was a little speechless when he listened to the voice in the courtyard, what happened today? Isn't the IQ tortured by the case enough? But I didn't speak, so why should I be included!

"We're here in Beiyuan Lane, come and pick us up!" Zhang started depressed and didn't want to speak, so he took out his mobile phone and called his colleagues.

"Hey, this dead girl actually hung up on me, I'm really angry!" Cai Xuemei hung up the phone and complained.

"Auntie, don't be angry, there have been two cases that are more difficult recently, so everyone is busy solving the case!" Chang Ping defended Li Chaonan, it was better if he didn't come back, it would save him trouble.

"And when will we talk about this?" Cai Xuemei stared at Chang Ping.

"I don't know about this, she's not on time when she's busy, it's almost night!" Chang Ping smiled and shook his head.

"Hey, what is this little guy going to do? Why don't you let me hug it! Li Aoyun scratched at the stupid in confusion. Clumsy looked at Chang Ping and snorted, looking very anxious.

"It's going to go to the toilet, just put it on the ground!" Chang Ping said with a smile.

"How can it be done, it's not a pee!" Li Aoyun grabbed the stupid and didn't let go.

"No, just put it down, and it will go to the toilet on its own!" Chang Ping shook his head and explained.

"It goes to the toilet on its own?" Li Aoyun glanced at Chang Ping in surprise and put his stupidity on the ground. Clumsy turned around and ran into the bathroom.

"Hey, it's really gone!" Li Aoyun felt incredible, got up and followed. When I walked to the door of the toilet, I saw that my two hind legs were stepping on both sides of the toilet and were convenient, and I heard someone at the door turn his head to look at it, and when the convenience was over, he stretched out his front paws and pressed the flush switch. With a bang, there was a flushing sound in the toilet, and Clumsy jumped down from the toilet and ran past Li Aoyun. He jumped onto the bed and lay down next to Chang Ping.

Li Aoyun's mouth was so open that he could stuff a duck egg. Is this a dog? And such a smart dog? "How did it get there?"

"It's been so convenient since I was a child, I'm used to it!" Chang Ping stroked Clumsy's head dotingly, and Clumsy narrowed his eyes with enjoyment.

"How do you train?" Li Aoyun sat in his chair and kept staring at Ben.

"Didn't I say that the dog went to the toilet, and you made a fuss?" Cai Xuemei cleaned up the things on the table.

"Fuss? Have you ever seen a dog squatting on the toilet to pee? Have you ever seen a dog know how to flush after going to the toilet? Li Aoyun was despised by his daughter-in-law and was very reluctant, and said what he saw with his eyes in his eyes.

"What? Was it the toilet it flushed itself? Cai Xuemei looked at Ben Ben in surprise.

"So what do you think?" Li Aoyun glanced at Cai Xuemei.

"I thought you rushed it!" Cai Xuemei looked stupid in disbelief.

"It's, it's not just this, it's a lot, it saved my life twice and helped catch the bandits twice!" Chang Ping said proudly.

"What? And something like this, tell me about it! Li Aoyun immediately became interested, and Cai Xuemei also sat on the chair.

"That time was to solve the case of a big drug lord, the big drug lord hired a large number of killers to kill us in order to cut off the clues, and I just got home that day..."

"Uncle, where can I go up to the roof?" Zhang started a few people to the Wenyuan community, and Liu Yang stopped an uncle and asked.

"From the west side of the building, there is a ladder over there, but you have to be safe!" The old man stretched out his fingers.

"Okay, thank you, uncle!" Liu Yang nodded in thanks, and walked over with Zhang Qiqi and Li Chaonan. The three of them walked to the west side of the building, and sure enough, they saw a ladder made of steel inlaid in cement, leading to the roof.

"I'll come first this time!" Li Chaonan said and grabbed the ladder and climbed up.

"Be careful!" Zhang Qiqi admonished.

"yes, got it!" Li Chaonan had already climbed a third of the way back to the words.

"I'm up too!" Liu Yang also went up the ladder as he spoke, and Zhang started to follow behind without saying a word.

Li Chaonan climbed to the top of the mountain and looked at his feet, and a layer of linoleum was laid on the entire roof. With a sigh in his heart, he walked straight forward, took two steps and stopped. The linoleum is black and somewhat sticky in the sun

(This chapter is not finished, please turn the page)

, so walking on it will be a little sticky to the feet, and not only that, but the soil on the soles of the shoes is also sticky off, and you can probably see the shape of the footprints. With this discovery, Li Chaonan came to his senses again, and hurriedly walked forward, until he reached the roof of the victim's unit and began to look carefully.

"Did you find anything?" Liu Yang, who was following behind, asked.

"Looking!" Li Chaonan said without raising his head. How can there be no footprints? By the way, they are all wearing foot covers, and they will definitely not leave a trace. So he strode to the edge of the building, and this time he finally made a discovery, because the building was relatively old, and the cement had weathered a little under the long-term wind and sun, and a new trench appeared on the edge of the building.

"Did you find anything?" Zhang Qiqi walked to Li Chaonan's side.

"This should be a trace of a lanyard and a safety rope!" Li Chaonan pointed to the trench and said. The width of the groove is about 18mm-20mm, the diameter of the standard vertical safety rope is 16mm-18mm, and the ordinary safety rope is made of nylon, etc.; High-strength safety rope, made of Dyneema, Dupont wire, high-strength wire; Special safety ropes, such as fire safety ropes, are made of inner 4.3mm steel wire ropes, and the outer fiber skin is braided; The marine corrosion-resistant safety rope materials are Dynema, Past, and polymer polyethylene; The material of the high-temperature rope safety rope is Kevlar, which is capable of long-term normal operation in the range of -196°C to 204°C. The shrinkage is 0 at 150 °C, and it does not decompose or melt at a high temperature of 560 °C; Heat shrinkable sleeve safety rope, the inner core is synthetic fiber rope, and the outer skin is heat shrinkable sleeve, which is wear-resistant and waterproof. If the cement is ground out of such a deep groove, then there must be fine fibers left inside. Thinking of this, he immediately put on gloves and gently scraped off the sand in the trench with tweezers and put it into a bag.

"Since you're going down from here, the residents below will definitely find something, go down and ask!" Zhang turned around and walked back.

"Team Zhang, there's still a discovery here!" Liu Yang made a discovery at the root of the lightning rod on the roof of the building, and found strangulation marks on the rusty iron pillar.

"Collect this rust and go back to the test!" Zhang Qiqi walked up to him and looked at the rust that fell on the ground and said.

"Okay!" Liu Yang put on gloves and put the rust into the bag, and the three of them searched the roof again and went downstairs without finding any other clues.

"Bang bang bang", a knock sounded in the hallway.

"Who?" An old lady wearing reading glasses pushed open the door and looked at the three of them standing in the doorway.

"Auntie, didn't you have an accident downstairs, we are the police looking for you to find out some information!" Li Chaonan said to the old lady with a smile.

"Oh, what's the matter? Just ask! The old lady looked at it for a moment, and the three of them pushed down their reading glasses.

"Auntie, did you see a head float past your window last night?" Liu Yang took a step forward and asked.

"What? The head? Floating in front of the window? Young man, you've watched too many ghost movies, haven't you? The old lady looked at Liu Yang with strange eyes. If I see it, can I still stand here and talk to you? I'm scared to death!

"No, Auntie, did you mean did you see a headless head floating out of your window?" Zhang Qiqi was a little anxious and quickly took over.

"Are you sick?" The old lady was stunned for a moment and suddenly asked.

"Auntie, we are not sick, I just asked you if you have seen people passing by in front of your window!" Liu Yang explained with a wry smile.

"My house is on the sixth floor, how can anyone pass by? It's really sick! "Bang", the old lady stepped back and closed the door......
