Jiang Huai responded, and after confirming that there were no other clues in the window, he went to Zhang Jingze to have a look.

Zhang Jingze came out of the bathroom, found nothing wrong inside, rummaged through the closet outside the door for a while, and asked: "Then...then if Liang Jiawen really asked his 'collaborator' to give the prisoner/ Forbidden, isn’t it quite possible that this person is Gao Kuiliang? After all, Liang Jiawen’s father, Liang Zhong, and Gao Kuiliang also collaborated before. In addition to the ‘B5-108’ on the door plate just now, we can actually interrogate Gao Kuiliang from this aspect Bar?"

"Not very good," Yan Cun replied, "I heard from Sister He before that if Yan Peifeng is an alert, mature and cautious old fox, then Gao Kuiliang can be regarded as an old bastard who has practiced for thousands of years. There is no definite evidence in hand to scare him away." He, on the contrary, will let him figure out the police's routine—hey hey!"

Seeing Ji Liao kneeling on the ground and turning on the flashlight to get under the bed, he hurriedly stepped forward to stop him: "You are so tall, can you get in! Don't get stuck inside and you can't get out!" He threw his things on the bed, "I'll come, I'll come, give me a light."

"Yeah," Ji Liao didn't evade much, since it wasn't easy to move around because of his body shape, he squatted aside and took a picture of the bed floor with a flashlight, "I just felt a bump here, check if it's right. Dark grid, be careful."

"Hmm, cough, cough!" Choked by the dust, Yan Cun couldn't help coughing a few times, lying on his back and carefully moved a few steps inside, "Okay..."

With the help of the light, he saw a square opening on the bottom of the bed, and a small electronic digital screen was inlaid on it. He touched it lightly with his hand: "It's a dark grid, and there is a four-digit electronic password box on it."

Ji Liao had a bad feeling: "Don't touch it, don't touch it randomly!"

Yan Cun replied "Okay", and quickly withdrew his hands, fearing that he would accidentally touch the password box, he tried his best to stick his back to the ground, and stretched out with one hand: "Ji Liao, get me the phone, I'll take a picture."

Ji Liao handed him the phone.

Jiang Huai suddenly became a little nervous, his whole body tensed up, and he called out to Zhang Jingze: "Go, find the hotel manager."

"Ah... good!" Zhang Jingze ran to the elevator in two or three steps.

The hotel manager went back to the room with Zhang Jingze, was shocked by what they said, broke out in a cold sweat, and looked under the bed for a while at the hidden compartment that had appeared out of thin air, revealing that he had no idea that there was a hidden compartment installed here.

Originally, this corner was not easy for people to find, and there was no reason for the cleaning staff to climb in to clean the bottom of the bed, and they didn’t pay too much attention to it—it’s just that this thing is really a bit evil, and I don’t know what’s hidden in the secret compartment. They didn't dare to act rashly to order something, so they had to ask Zhang Jingze to go with the hotel manager to get the record of staying in Room 108 in recent years.

The technicians at the Dongcheng branch failed to restore the hotel surveillance, and the other network investigators of the detachment are also trying hard, but there is little hope, so they still plan to contact Almighty Xiaowen, who was discharged from the hospital and recuperating at home.

All-round scout Wen Lianyi's body injury has healed more than half of the time, and there is almost a month left in the recuperation vacation. Hearing them talk about the case every day is really itchy: "My God, I finally came to work! It's earth-shattering, I'm so bored at home!"

"Yeah, I'm here to work. I'm afraid you will die after returning to the team after being discharged from the hospital. I will give you some tasks to practice your hands." Yan Cun said.

While talking about the case with Wen Lianyi, he arranged tasks for Jiang Huai and Ji Liao, and the three of them began to conduct a second round of search in the house, focusing on small corners such as the back of the bedside table and the top of the wardrobe that are difficult to find. , to see if there are other secret compartments or password papers hidden.

"Retrieve the deleted surveillance video?" Wen Lianyi thought for a while, "If other technicians in the detachment cannot restore it, it is likely that it was overwritten by other files, and it is very difficult to restore."

"Well," Yan Cun responded, "The person who deleted the record may have taken some measures to prevent the video from being restored. It is more troublesome. Try your best. It doesn't matter if you can't restore it."

"I'll try to go back to the game later," Wen Lianyi asked, "Are you on the scene now?"

"At the place where Liang Jiawen's mobile phone location last appeared, I'll go to the Dongcheng branch to look at the evidence later, and you can see if there is anything wrong with the location system," Yan Cun said, "I found a hidden compartment under the bed here. , there is a combination lock, but it is not connected to the Internet, I guess you can’t check it there, you have to look in the house for other clues.”

"That's fine," Wen Lianyi replied, "Then I'll give it a try, and I'll call you if there's a result."

After hanging up the phone, the three continued to search the house for a while.

After searching for nearly 10 minutes, they were greatly disappointed this time—except for the hidden compartment just found under the bed, nothing was wrong in the room, not to mention the password paper, and they didn’t even see a number How many.

In desperation, Yan Cun climbed back to the bottom of the bed again, and carefully tried to enter a password to enter - the password box displayed the word 'error', and there was no response after that, it seemed that it was really just an ordinary, non-dangerous password It's just a lock.

"The password box is composed of pure numbers, four digits, and there are too many permutations and combinations."

The back of the uniform was rubbed all over with dust, Yan Cun's obsession with cleanliness was a bit unbearable, so he asked Ji Liao to come over and pat the dust for him.

"Found nothing?" he asked. "Is there any other way? Do you really want to try them all?"

"No, I have taken apart the back of the toilet tank and found nothing," Jiang Huai also nodded, "Why don't you ask someone to take it apart directly? How long will it take to try one by one?"

"Hmm..." Yan Cun sighed, "Where's Ji Liao? Ji Liao didn't find anything either?"

"Not in the house," Ji Liao said, "but there must be a password paper."

"?" Yan Cun asked, "How do you say it?"

Ji Liao walked towards the window sill: "The positioning system of Liang Jiawen's mobile phone happened to be broken at this place. The car just happened to be parked downstairs, and then the mobile phone was thrown back into the drawer of his house. If you don't want others to know his whereabouts, That would be a little too careless.”

"..." Yan Cun realized, "So that person wants to lure us here?"

"It should be," Ji Liao nodded, "If all they did was to lure us here, to let us discover this secret compartment, and to let us find what's inside, then they wouldn't even need a password. Don’t give it to us, let us try one by one—”

Yan Cun was stunned for two seconds, then suddenly remembered a certain word in Ji Liao's words, and followed Ji Liao with small steps: "No inside the house, meaning outside?"

"If it were me, I couldn't let the cleaning staff clear the code, and I had to make sure that the tenants wouldn't find it easily, and I'd make sure that the police wouldn't find it so easy..."

"Outdoor air conditioner!"

"Yes." Ji Liao opened the window and looked in the direction of the air conditioner directly below - there seemed to be something fixed in the small gap near the wall.

It's a little far away, and I can't reach it with my hands, and the fifth floor is indeed a bit high, so Yan Cun said: "Jiang Huai, go back to the car and get a rescue rope."

Jiang Huai responded "OK" and went downstairs in two or three steps, but after a few minutes, he was out of breath and returned to the fifth floor with the rescue rope.

After fixing the rescue rope, Yan Cun grasped the rope with both hands and carefully crossed the window, and moved down a little distance—the small thin iron box was fixed on the inside of the air conditioner external unit by wire. not easily found.

"Wait a minute," Yan Cun said, "I'm a little nervous, give me something stuck underneath, I'm afraid my hands will shake and I won't hold it firmly and it will fall."

Ji Liao responded and handed him a small wooden board.

After clamping the small wooden board right under the iron box, Yan Cun found that there seemed to be a small box fixed under the external unit of the air conditioner. After that, he asked Jianghuai to lower the rescue rope.

"There's a wooden box underneath."

The rescue rope was placed under the external unit of the air conditioner. He squinted his eyes and studied how the wooden box was fixed: "It's quite big, about the size of a tissue box, and it seems to be attracted by a magnet. Pretty strong."

"Can you break it off?" Ji Liao looked around the back room, "There are no tools."

"It's okay, let me try." Yan Cun breathed out.

Afraid of throwing the wooden box out with force, he blocked half of his body under the wooden box, grasping the rescue rope with one hand, and carefully dismantled the wooden box with the other hand.

"What is this for? Solving puzzles?" Back in the room, put the things together on the table, Jiang Huai put away the rescue rope, "A dark compartment, wooden box, and iron box? Are you free?"

Yan Cun first went to the bathroom to wash his hands, returned to the room and began to study the two small boxes, and focused on the big wooden box. When he was underneath it just now, he could see what it was: "A homemade marble maze."

"??" Jiang Huai didn't understand at once, "What... what marbles? What maze?"

"The one that moves the ball through the maze," Yan Cun asked, "Is the marble you just found still there?"

There is a groove hole for marbles on the side of the wooden box. There are no marbles. There are more than a dozen trap holes in the maze. One of the small holes is marked with the word "exit" by an arrow. There is a long coin slot at the bottom of the wooden box. .

"Ah... yes, it's in my pocket."

Jiang Huai handed the marble over, seeing that he was moving quickly and trying to stuff the marble into the groove, he hurried forward to stop him: "Wait, what is this? It can't be a bomb, can it? It won't reach the exit and blow up directly." right?"

"Ah?" Yan Cun blinked, weighed the wooden box, "No way? It's quite light."

"How do you play this? How stupid? Do you know how to play this?" Jiang Huai was a little nervous, "This is a one-life pass, right? If you enter the wrong port, there will be no marbles!"

"Yes." Ji Liao said.

"Yes," Yan Cun nodded, "I used to play this game when I was young, and I've played anything harder than this one. It should be fine. Don't be nervous."

Ji Liao froze for a moment, glanced at him for some unknown reason, and quickly looked away.

"...Why do you all know it??" Jiang Huai breathed out, "Okay, play carefully...how about you practice your hands first?"

Before he finished speaking, Yan Cun decisively stuffed the marble into the entrance of the maze, quickly dodged left and right, and perfectly avoided all the trap holes. In less than ten seconds, the marble successfully reached the target exit.

There was a "click" sound from the wooden box, and a small key popped out from the coin opening at the bottom.

Yan Cun took out the key and laughed, before he had time to say: "It's not necessary, I'm just such a skill that can show off, so I don't want to show it off to you."
