As a local policeman, is it appropriate for you to take over the job of a criminal policeman?

The secret room disappearance case that Li mentioned this time happened in Mao Xiaolin's room.

According to Mao Renfeng and others, Mao Xiaolin came back at about 8 o'clock last night, and has not been seen since entering the room. The old couple did not notice it. Then at around 7 o'clock this morning, they called Mao Xiaolin to get up for school, and found that the door was locked from the inside.

And no one answered no matter how they called, so they went around to the back window and looked inside, only to find that there was no one inside, so they called the police.

When Chief Li brought his men over, they couldn't find the key, so they broke into the room directly. There was no one inside.

The doors and windows were locked and the people were gone, so Chief Li immediately requested support.

"Now that the person is gone, couldn't Mao Xiaolin have just closed the window, locked the door and left? Does this count as a secret room?" Yu Haifeng said unhappily. This is just nonsense.

"No, Captain Yu, look at this." Chief Li took out his cell phone and enlarged a photo to show Yu Haifeng.

The photo was taken through the window, and it clearly showed that there was a latch on the back of Mao Xiaolin's door, which means that it could only be done if someone was inside.

Ye Lin frowned and asked, "Why do you use this kind of latch at home?"

Nowadays, most people don’t lock their bedroom doors separately. Even if they do, they are the kind that can be opened by just turning a twist. No one would install a latch on the back.

"Mao Xiaolin installed it himself. He didn't want the two old men to come in and disturb him." Li explained, "Also, he was looking at the computer when I came in last time, so he probably doesn't want anyone to come in like this again."

Yu Haifeng looked at the photo on his phone, then looked at the window in the room. It was an old-fashioned window that pushed outwards, with a straight-up and straight-down latch inside, which was now inserted into the card slot.

"So this is what the window is like?" Yu Haifeng asked.

"Yes, Captain Yu, otherwise I wouldn't have invited you here. It gives me a headache seeing this situation." Suo Li began to complain.

Ye Lin and the others now basically understood what the secret room that Li mentioned was. The door and windows were latched from the inside, so how did that person leave?

Where did everyone else go?

Not to mention Li Suo was at a loss, Yu Haifeng and the others were almost at a loss too.

"Old Zhao, take them around the house and check the cameras."

"Xiao Wang, Xiao Sun and Qi Shan, visit the nearby residents to see if there are any clues."

"Linzi, just watch here for now. Wait for the technical department to come over and see what they can find out."

Yu Haifeng had no idea for the time being, so he just did it according to the previous routine.

Ye Lin put on shoe covers and walked into Mao Xiaolin's room carefully.

The room is not big, only about ten square meters, which is more than enough for him to live in. In addition to a bed and a wardrobe, there is also a study desk and a refrigerator.

As he is in the second grade of junior high school, he should have a lot of homework and his study desk should be piled with study materials.

But in fact, there was no textbook on Mao Xiaolin's desk. He only saw some colorful magazines, the kind that were marginal. Ye Lin opened them and flipped through them, and sure enough, they were all about thieves and prostitutes, and some of the articles were very explicit.

There was a computer on the study desk, with a pair of big headphones. I don’t know why a junior high school student like him would need a computer. Ye Lin remembered that he only used a computer after he went to college.

The bed is quite simple, just a single bed. It's already October, so I changed to a thin quilt, which is now neatly folded on the bed with no signs of having been used.

As for the refrigerator, Ye Lin was a little confused as to why a refrigerator was placed in the bedroom, but he understood after opening it. It was full of drinks and milk. Looking at the drink bottles in the trash can, Ye Lin probably understood that the old couple put it there on purpose because they loved him.

After taking a general look at the environment, Ye Lin turned his attention to the doors and windows.

The door lock had been broken and its original appearance could not be seen. It looked like someone had broken in violently.

The latch inside was still fixed to the door frame. After it was knocked open, a piece of the wooden strip of the door frame was torn, but the latch was still there.

It can be basically seen that it should have been fixed very firmly at the beginning, and the latch was in the locked position.

Another thing is the window, which is really old-fashioned. Ye Lin remembers that his home used this type when he was a child, but most houses now use the new sliding windows, which look better.

Outside the window is a small courtyard, which Mao Renfeng had enclosed himself. Most of the residents on the first floor would do the same, so it is hard to say whether it is an illegal construction or not.

The yard was enclosed with no door, and inside were some sundries and a few pots of flowers and plants, but due to lack of care they had grown into weeds.

Ye Lin did not go in to take a look. Some professional matters should be left to professionals. The technical department will go through all the places here carefully and find any fingerprints and footprints. This is something that his naked eyes cannot solve.

Ye Lin walked out of the room. There were no useful clues for the time being.

Yu Haifeng was still contacting support forces. When he saw Ye Lin coming out, he quickly hung up the phone and asked, "How is it? Is there anything special?"

"It's hard to say. It does look like a secret room, but I don't know how it was done."

"Okay, no rush. Let's go to Li's place to meet first and let Lao Zhao take them to find out the situation first." Yu Haifeng patted Ye Lin.

The police station was not far from here. After entering, Chief Li quickly prepared a meeting room and prepared tea and cigarettes for the two.

"Captain Yu, please help me. I'm so fed up with this Mao Xiaolin issue." Before Yu Haifeng could say anything, Li Suo started complaining.

"Tell me, I wanted to ask you what happened in the chess and card room, but I saw you were giving me a look." Yu Haifeng said.

"There's nothing I can do. To be honest, Captain Yu, I really wish this guy would just die." Li Suo said hatefully.

Yu Haifeng's face darkened. "Lao Li, you are a policeman, what nonsense are you talking about?"

Ye Lin also looked at Li Suo in astonishment. How much did he hate Mao Xiaolin for saying such unprincipled words?

Li Suo shook his head, looked at the two men, and said, "You two, you don't know what Mao Xiaolin has done. If you knew, you would definitely think the same as I do."

Next, Chief Li talked about what Mao Xiaolin had done during this period, which really shocked the two of them.

After Chief Li forcefully locked up Mao Xiaolin for a few days last time, this guy behaved himself for a few days.

But just a few days later, this guy did something that was outrageous to both humans and gods.
