"Yes, it's the seat number that Xia Lan pointed to me, the number ten in the third row. Pen & Fun & Pavilion www.biquge.info" Du Hui said, pointing to the seat downstairs.

Xu Tian looked through the hole in the lifting platform, and he could just see where Du Hui was sitting.

"You can see the lift platform when you sit in the audience, right?" Xu Tian asked.

"I can see the hole, but nothing else."

"Xia Lan should have been hanging in the air for half an hour before the performance, are you sure you didn't see Xia Lan's dangling feet?"

"I don't see it."

Xu Tian glanced at the lifting platform that rose from the height, and then at the two steel wires that went from the lifting platform to the bottom of the stage.

"What's wrong? Did you find anything? Team Leader Chen asked.

"I know the cause of Xia Lan's death!" Xu Tian said with a frightened face.

"What the hell is going on?"

"Du Hui didn't see Xia Lan's feet above the stage on the audience, and Li Rinin didn't see Xia Lan when he entered the preparation room, which means that after the three teachers helped Xia Lan prepare for the performance at half past nine, Xia Lan disappeared from Du Hui and Li Rinrin's sight."

"You won't say that Xia Lan walked out of the preparation room at that time, right?"

"This is impossible, Xia Lan's body has been hoisted on the lifting platform by two steel wires, if outsiders don't help, it will be very difficult for Xia Lan to get rid of the steel wires, besides, at that time, Xia Lan is about to perform on stage, and Xia Lan herself will not be able to leave the preparation room."

"So where did Xia Lan go?"

"You can see the height of this preparation room, it's almost as tall as a two-story building, about the height of the stage downstairs. The reason why Du Hui didn't see Xia Lan's feet that should be hanging in mid-air was because Xia Lan was removed by the murderer. And the reason why Li Rin didn't see Xia Lan after entering the preparation room was because Xia Lan was hanging on the top of the preparation room at that time. ”

"What do you say? It's unlikely, right? ”

"The height of the two-story building is almost six meters, if Xia Lan was hung flat on the roof of the preparation room by the murderer, then Li Rinrin didn't see Xia Lan It is completely reasonable, if the preparation room only turns on the floor lamp, it will be more able to cover Xia Lan who is hanging flat on the roof."

"Then how the hell did Xia Lan die?"

After the three teachers prepared Xia Lan, the murderer dragged Xia Lan, who was hanging in mid-air, to the roof of the preparation room, and then strangled Xia Lan with a mobile phone charging cable, and then took off all of Xia Lan's clothes, used those clothes as ropes, and tied Xia Lan to the roof of the preparation room. The roof of the preparation room of the stage is different from the house, in order to hang the steel wire above the stage, there will be a steel frame, and Xia Lan's body will be tied to the steel frame with Xia Lan's clothes, from the head to the waist, and then to the feet, as long as you tie a few more parts, you can hang Xia Lan flat on the roof, of course, these clothes are not tied to the dead. After making these preparations, the two wire ropes that were supposed to be hooked on Xia Lan's belt were tied to Xia Lan's waist, and all the preparations were completed. As soon as Xia Lan's stage time arrived, the lifting platform ** moved to the bottom of the stage, and after the two wire ropes were straightened by the lifting platform, the clothes that were originally tied to Xia Lan's body were dragged away, and Xia Lan's body was naturally dragged down by the two wire ropes, and Xia Lan's clothes were all scattered in the preparation room, and then Xia Lan's body returned to the right position and landed on the stage with the lifting platform. ”

"But...... Why did the killer do this? Isn't it okay to just strangle Xia Lan? What's the point of letting Xia Lan's body come down? ”

"I think it should be revenge, the murderer's hatred for Xia Lan has reached the extreme, it stands to reason that as long as Xia Lan is strangled and Li Rinin is guided into the preparation room, Li Rinin can be blamed, but the murderer is not satisfied with this approach, and must let Xia Lan's body be exposed on the stage, which shows that the murderer's psychology has been completely distorted."

"Who could the murderer be?"

"I can't conclude yet, now I just deduced Xia Lan's death, and if I want to find out the murderer, I need to collect further evidence."

"Then let's quickly investigate Xia Lan's interpersonal relationships! Let's start with Xia Lan's bank account. ”

"Yes, as long as you find out where the money Xia Lan defrauded goes, you may be able to find out the murderer who killed Xia Lan."

While Team Leader Chen went to the bank to investigate, Xu Tian came to the audience downstairs, Du Hui's three rows of No. 10 made Xu Tian feel very curious, why Xia Lan pointed out this position to Du Hui, Xu Tian was a little puzzled.

Xu Tian simply sat on the third row of No. 10, and as long as he looked up, he could see the lifting platform.

"Xu Tian, haven't you left yet?" Sitong walked over and said.

Si Tong ...... You came just in time, too many things have happened in the past two days, and I didn't take time to take you to the hospital, so I just have time this afternoon, let's go to the hospital for a check-up! ”

"I don't want to trouble you too much, in fact, Siyan asked me to come to you, the old village chief sent us a lot of souvenirs, if you have time, go get some!"

"Then I'll go at night! By the way, on the night of the power outage in 504, you said you heard a loud door closing, did you hear any other sounds after that? ”

"I don't remember any other sounds, and my sister and I slept after that."

"There is another thing, that is, the screenshot of the video taken by Shao Xiaowen, when Xia Lan looked back at the door and intercepted you, can you remember the situation at that time?"

"This ...... I really don't remember. Sitong looked apologetic.

"It's okay." Xu Tian looked up at the lifting platform and said with emotion.

"What are you staring at the stage?"

"I'm wondering how the killer got out."

"What did you say?"

"I already know Xia Lan's death steps, but I haven't figured out who hung Xia Lan on the roof of the preparation room, in that half an hour, except for Li Rinrin, no one has entered the preparation room, and the place where the lifting platform is controlled is also downstairs, it stands to reason that no one should be able to enter the preparation room after half past nine to hang Xia Lan."

"I don't think it's so complicated, I've been involved in homicides, so I know that no matter how confusing the case may seem, the truth is not that complicated, and as a participant in a case, sometimes you may not think about it that much."

"Didn't think about it that much?" Sitong's words made Xu Tian seem to remember something.

"Are you alright?" Looking at Xu Tian, who was stunned, Sitong stretched out his palm and swiped twice in front of Xu Tian's eyes.

Xu Tian grabbed Sitong's hand, and at this time Xu Tian finally showed excited eyes.

"Sitong, thank you!" Xu Tian said with a smile.

"Huh? Did I do anything? Why thank me? Sitong felt a little inexplicable.

Buzzing......

Team Leader Chen sent Xia Lan's recent bank statement.
