The competition time was on the morning of the second day, and after seeing the competition venue, Mr. Lu Zhiwei took the students back to the hotel.

When she opened the door, she glanced at the door number next to her and knew that Jin Lei lived next to her, but she had to be vigilant and checked the environment of the hotel again.

The organizing committee arranged for the contestants from all over the world to live in the same hotel.

Yunxi's room is on the third floor near the first staircase, and everyone takes the elevator up and down the stairs on weekdays, and the elevator entrance is only separated from the staircase safety passage by one aisle.

Back in the room, Yun Xi was keenly aware that someone had entered her room, and she put her disposable slippers on the carpet between the bed and the TV cabinet before going out, and the direction and position of the shoes were aligned with the center of the carpet pattern, and now the shoes were moved.

Before going out, she hung a Do Not Disturb sign at the door, and the hotel had been cleaned before check-in, and she placed her shoes just a subconscious vigilant habit, but she didn't expect someone to really enter her room.

Putting down her bag, she took off her shoes and began to carefully walk around the room.

After some inspection, even under the table under the bed, and even in the TV, she had opened and looked through it, and there was nothing else in the room.

She couldn't help but breathe a sigh of relief, her tense nerves finally relaxed slightly, and she lazily lay down on the quilt, and as soon as she lay down, the back of her hand seemed to be pierced by a fine sandstone, and she sat up suddenly.

On the white sheets, she carefully touched them back and forth, and there was a lot of white sand and gravel powder in her palms.

Yun Xi suddenly raised her head to look at the cigarette detector above her head, in order to prove her conjecture, she moved the table and chair and stood up, took the screwdriver of the multi-purpose Swiss Army knife she brought over, and unscrewed the screws on the cigarette detector one by one.

Sure enough, the wires in the smoke detector have been cut!

Without much thought, she screwed the screws back, and quietly pushed open the floor-to-ceiling window and walked to the edge of the balcony.

She took the toothbrush she took out of the bathroom, wrapped the written note and threw it to the balcony of Jin Lei's room, and when she heard the sound, Jin Lei quickly walked to the balcony.

"What's wrong?" Jin Lei glanced at the toothbrush on the balcony, picked up the toothbrush and the note and looked at it, and his dark eyes suddenly sank.

"Come over and talk about it!"

Yun Xi nodded, supported the railing with both hands, and turned over and quickly jumped onto Jin Lei's balcony with his sewer pipe.

"Why don't you go through the front door?!"

Jin Lei looked at her and finally stood on her balcony, and breathed a sigh of relief, this is the third floor, if you accidentally fall down, you will not die and be disabled!

"The other party broke the smoke detector in my room, and if they come prepared, I guess the surveillance in the hallway is also under their control."

"Smoke detector ......" Jin Lei narrowed his eyes slightly, and a cold cold light swept through his eyes, "Destroy the smoke detector, don't you want to set fire to your room?" I'm afraid it's not that simple, right? Have you looked for it, have you found anything else? ”

"No, I've searched everywhere I can, and I finally found out that they used the smoke detector."

"There's another place you haven't looked for."

"Where?"

"Inside the toilet flusher!"

"I ...... I really haven't looked for it!! ”

"Let's go and see! I'm curious what the hell they're doing in your room! ”
