Although the wooden door of No. 489 is very old, and even has a thick layer of dust on it, only the doorknob is shiny and black, and there is not much patina, so it is obvious that people often enter and exit here.

Han Bing also glanced at the doorknob when he heard this, and then coldly glanced at the middle-aged woman, thinking that the middle-aged woman was lying.

"Ao, although they moved away, Lao Sun planted a yard of flowers and vegetables here, and he has to come every three or five times!"

The middle-aged woman hurriedly walked out, looked at the doorknob, and said calmly.

However, Lin Yu didn't believe her at all, and directly glanced at the hundred people, and then the two of them jumped and climbed into the wall very neatly.

"Hey, hey, why do you just go into other people's houses!"

When the middle-aged woman saw Lin Yu and Bairen Tu flipping in, she suddenly became anxious, and waved her hand and shouted.

"Don't move!"

Han Bing glared at her coldly, then took out his ID from his arms and said coldly to the middle-aged woman, "We are investigating according to law!"

The middle-aged woman was slightly stunned when she saw the document in Han Bing's hand, her face changed, and she didn't dare to speak again.

After Lin Yu and Bairen Tu turned into the courtyard of No. 489, they found that the middle-aged woman was right, the courtyard was indeed full of flowers, plants and vegetables, and the whole hall looked old and dilapidated, and it really didn't look like someone had lived in it.

Without waiting for Lin Yu's orders, the hundred people slaughtered directly into the hall with an arrow step, went in to search it, and then walked out and shook his head at Lin Yu, indicating that nothing had been found.

At this time, Han Bing also turned over from the wall very neatly, saw a few dilapidated halls, and found that he could see it clearly at a glance, so he couldn't help frowning, and asked, "How is it, have you found anything?!"

Lin Yu looked around the courtyard and found that there was nothing abnormal, then shook his head, and said helplessly, "No ......"

Han Bing was a little reluctant to carefully check the courtyard and the small backyard behind the house again, and saw that there was indeed nothing abnormal, so he couldn't help but sigh a little disappointed, pointed to the next door, and said, "Let's go to No. 487 to have a look!"

Because she had seen the documents in Han Bing's hand just now, and she had also seen the skills of Han Bing, Lin Yu and others, the middle-aged woman didn't dare to say anything, and she was very cooperative with Han Bing and the small courtyard they had built in their house and behind the house to carefully inspect it.

"Sir, you...... What the hell are you looking for?!"

The middle-aged woman saw that Lin Yu and Han Bing were even rummaging under the wardrobe and rice jar, and asked with some confusion.

"Don't ask what you shouldn't!"

Han Bing said coldly with a calm face.

The middle-aged woman swallowed her saliva and didn't dare to speak again.

Seeing that there was nothing suspicious about the middle-aged woman's house, Lin Yu and Han Bing couldn't help but sigh softly, it seems that this No. 488 really doesn't exist!

After Lin Yu and Han Bing walked to the courtyard, they found that Bairen Tu had jumped onto the roof of a utility room in the courtyard, and was sweeping around with their eyes.

Lin Yu's heart moved when he saw this, yes, if he jumped on the roof, he might be able to see it more clearly.

Immediately after that, he ran up, kicked the wall and jumped onto the roof very neatly, and swept around with the Hundred People Tu.

Because they were standing high enough at this time, they could see almost the entire bungalow nearby.

However, the structure of the bungalows in this area is much more messy than they imagined, and the yards are either set up with wooden frames, supporting the sunshade nets that have not been replaced in the summer, or there are various odd-shaped aluminum alloy rain rides and other sundries on the roof, which are not clear at all, and most of the square houses are the same as No. 487 and No. 489, with an extra back wall built to make a small backyard for housing sundries, and some houses facing the street are almost built back to back, just to build a row of doors facing the street, which looks messy。

Lin Yu and Bairen Tu stood and watched for a long time and didn't see anything strange, because the structure of this house was too complicated.

At this time, someone in the next few courtyards saw Lin Yu and Bairen Tu standing on the roof, and shouted at them angrily.

Seeing this, Lin Yu and Bairen Tu didn't stay any longer, and hurriedly jumped down.

"Did you find anything?!"

Han Bing asked urgently.

Lin Yu didn't speak, he shook his head with a somewhat lost expression, obviously very disappointed.

Han Bing suddenly sighed a little helplessly, and said in a low voice, "I said a long time ago, even if I came here, it would be a trip for nothing...... Could it be ...... As Zhang Youxi said, this address is really a spam text message?!"

Lin Yu squinted his eyes, thought about Zhang Youxi's previous reaction, and always felt that that calmness was deliberately pretended by Zhang Youxi, shook his head and said, "I don't think it's like it!"

"Well, let's go back and talk about it!"

Han Bing sighed helplessly, seeing that he hadn't found anything, and he didn't plan to spend any more here, he turned around and walked out.

Lin Yu and Bairen Tu also immediately followed, and after getting into the car, Han Bing started the car and rushed to the city.

"Wait!"

Not long after the car drove out, Lin Yu, who had been frowning and contemplating, suddenly shouted at Han Bing, as if he had thought of something.

"Squeak!"

Han Bing hurriedly braked and glanced back at Lin Yu with some confusion.

"Brother Niu, do you remember, when we jumped on the roof, we saw that the small backyards behind the houses of seven or eight residents in a row of No. 487 and 489 were all covered with blue rain rides, so we couldn't see the situation in the backyard clearly, right?!"

Lin Yu turned his head and said to Brother Niu.

"yes, but didn't we go into the backyard from their kitchen, they all like to have an extra space at the back of the house as a small backyard!"

Bairen Tu frowned and said, in fact, it is a small backyard, but the width is no more than one meter, and the length is also extremely short, which is specially used to hold sundries.

"Yes, everybody has it, but don't you think it...... Does the backyard of 487 seem to be narrower than the backyard of 489? But when we look at it from the rooftop, their backyard seems to be as wide!"

Lin Yu said in a deep voice, when he looked at it from the roof, he always felt that the backyard of No. 487 was one and a half to two meters wide, but in fact, when he and Bairen Tu went to investigate, it was only one meter wide.

Bairen Tu frowned, pondered for a moment, raised his head and said to Lin Yu, "Sir, do you think there's something greasy in there?!"

Lin Yu nodded and said, "I don't know, but to be on the safe side, it's better to take a detour to the back!"

Han Bing didn't say a word when he heard this, he turned around directly and drove towards the position of the back wall of No. 487 and No. 489 just now, but because the aisle was very small, the car couldn't drive in, so Han Bing directly parked the car at the intersection, and then the three of them got out of the car and walked in.

After walking to the courtyard wall behind 487, Han Bing glanced left and right, and saw that the back walls of the house were almost the same neat, so he said, "The walls are all the same, you can't see anything wrong from the outside!"

Lin Yu's face was solemn and he didn't speak, he glanced at the courtyard wall that was more than two meters high, touched the wall with his hand, and carefully checked the wall, and saw that it was a courtyard wall made of standard red brick cement, and there were absolutely no organs and secret doors.

He looked up at the aluminum alloy rain ride that stretched out of the back wall more than ten centimeters above, and said to Bairen Tu, "Brother Niu, do you bring a knife, find a way to pry the rain ride open, look down, and see if it is the backyard of the eldest sister's house just now!"

"Good!"

Bairen Tu nodded immediately, then took out a dagger, inserted it into the brick crack, and then jumped hard, stepped on the dagger, climbed the wall with his hand, and took out a dagger from his waist again, when he was about to pry open the rain ride, he put his hand on the rain ride, and found that the rain ride was actually active!

His eyes lit up, and he hurriedly dragged the rain ride in his hand, and found that the rain ride of about one square meter was really not one with other rain rides, and there seemed to be some live buckle connected!

He hurriedly tried to move the activity, and then pushed it up hard, and with a lift, he pulled the rain down the activity.

Bairen Tu glanced inside, his always expressionless face also changed slightly, and he turned around and said to Lin Yu in a low voice, "Sir, there is really a problem!"
