Liang Zichen glanced at the ground in front of him. Because the community where Han Mo is located is too old, the floor of the corridor is still concrete. I don't know if there are any properties in this community, in short, judging from the cleanliness of the ground, there should be none. I don't know how long no one has been cleaning the open space outside the gate of Han Mo's house, but I saw a layer of clearly visible dust falling on the ground. But thanks to this layer of dust, Wang Shen and Liang Zichen discovered some small details.

Liang Zichen stared at the layer of dust on the ground and looked at it carefully for a while. Actually, that's not accurate. What Wang Shen carefully observed was the footprints carved out of the dust. There are three households on this floor, and there are only two rows of footprints. According to common sense, Han Mo's house is uninhabited, so these two rows of footprints should lead to the other two families. However, this is not the case.

Liang Zichen found that one of the footprints led to the resident on Han Mo's left. And another row of footprints led directly to Han Mo's gate. On the contrary, there were no clear footprints at the door of the household on Han Mo's right. Therefore, through the observation of this row of footprints, Liang Zichen found that someone must have entered Han Mo's house.

After Liang Zichen figured this out, he finally understood why Wang Shen was waiting here. However, suddenly an idea flashed in Liang Zichen's mind again. Wang Shen and Liang Zichen couldn't determine the time when the mysterious person entered Han Mo's house, at this time, would the mysterious person have already left the house?

Liang Zichen thought for a while, and was about to tell Wang Shen the question he thought of. However, when Liang Zichen was about to speak, he held back the words that came to his lips again. Liang Zichen carefully observed the footprints on the ground again, if there were footprints entering the house, then there would definitely be footprints walking out of the house. Liang Zichen observed carefully and found that the row of clear footprints leading to Han Mo's door were all pointing towards the door of Han Mo's house. By the way, it means that that person is still in Han Mo's house now!

Liang Zichen thought of this and fully understood why Wang Shen was squatting here, and he didn't enter Han Mo's house until now. Liang Zichen moved his body and squatted to Wang Shen's left, waiting for the target to have nowhere to escape when he threw himself into the net.

Wang Shen kept looking at his watch, and the time passed minute by minute, but the target still did not appear. Wang Shen finally couldn't hold it anymore and slowly straightened up a little. At this time, Liang Zichen originally planned to follow Wang Shen to move his body. Wang Shen understood what Liang Zichen meant, and then immediately waved his hand at Liang Zichen, signaling him to stay in his original position.

Wang Shen just took half a step and lifted his feet back. Wang Shen seemed to think of something, and then took out his mobile phone and took a photo of the footprints on the ground. After taking the photo, Wang Shen carefully moved his steps and slowly approached the gate of Han Mo's house. Wang Shen finally walked to the door of Han Mo's house. He put his ear to the door and listened for a moment.

Suddenly, Wang Shen's face changed, and there was movement in the house. Wang Shen half-squatted by the door, hesitating for a moment what to do next. Wang Shen thought for a while, saw the mobile phone in his hand, and an idea came to him. Wang Shenwei closed his eyes and recalled the phone number of Han Mo's landline at home. Thanks to Wang Shen's own extraordinary memory ability, he accurately recalled Han Mo's fixed phone number. Wang Shen picked up his mobile phone and pressed Han Mojia's phone number on the phone.

After a while, the phone was connected. Wang Shen clearly heard the telephone ringing inside the room outside the door. At this time, the small sounds that had been in the room suddenly stopped. A smile tugged at the corner of Wang Shen's mouth as he held his phone close to his ear. Wang Shen's other ear was attached to the door, quietly listening to the movement in the room.

After a while, the phone was answered. Wang Shen didn't speak, because no one on the other end of the phone spoke. Wang Shen wanted to pretend to be the gas company's person who was urging the gas bill, but after thinking about it, he gave up the idea. Now, Wang Shen is standing outside the door, and Wang Shen may reveal his whereabouts as soon as he opens his mouth. Wang Shen and the mysterious person in the room were in a stalemate for a few minutes, and then the mysterious person in the room suddenly hung up the phone.

Wang Shen frowned and continued to listen quietly to the movement in the room. The movement in the room not only did not stop because of the phone call, but became more ...... Intense? Wang Shen thought for a while, guessing that the mysterious person in the room was probably in a hurry after receiving this mysterious call. But what is the mystery man doing in a hurry? At present, Wang Shen has not been able to make a more accurate judgment.

At this time, Wang Shen turned around and glanced at Liang Zichen, and suddenly smiled at Liang Zichen. Liang Zichen saw Wang Shen's smile, and he didn't know why he had a creepy feeling, and knew that there must be nothing good. Wang Shen smiled and returned to a serious expression, and did not say anything to Liang Zichen, but picked up his mobile phone and edited a text message.

After a while, Liang Zichen's mobile phone vibrated and received this text message from Wang Shen. Liang Zichen glanced at Wang Shen suspiciously, shrugged his shoulders, and waved his hand again, indicating that he could not understand Wang Shen's behavior. Wang Shen frowned and pointed to the mobile phone in his hand. Liang Zichen saw Wang Shen's expression and silently made an oK gesture.

Liang Zichen opened the text message, and the content was like this: There are people in the house. You go to the door of the unit building and pretend that someone from the gas company calls the landline of Han Mo's house, which is the phone found in Han Lin's house. Next you should know how to do it. Landline is ......

After reading Wang Shen's text message, Liang Zichen finally understood Wang Shen's thoughts, made an oK gesture to Wang Shen again, and then walked to the door of the unit building. Liang Zichen glanced at Han Mo's fixed phone number and called it with his mobile phone.

After a while, the phone was connected again. It seems that the mysterious person in Han Mo's house is still very curious. At first, neither Liang Zichen nor the mysterious man spoke. Liang Zichen sighed in his heart and said, "Hello, I'm from the gas company." Your gas bill has been in arrears for a long time, and we need to read the meter, and every time there is no one in your house. Are you home today? I'm going to come to read the meter, and by the way, please pay the gas bill. Liang Zichen's tone was slightly angry, and in a very professional and untired debt collection tone, he said the purpose of making this call in one breath.

There was silence on the other end of the phone for a while, and then the mysterious man really spoke: "I'm really sorry, I'll pay on time." ”

Liang Zichen was startled, it was a man's voice. Judging by the voice of the voice, he is not very old. After listening to the mysterious man's words, Liang Zichen pretended to be angry and said: "Pay on time, pay on time, I haven't paid it for so long!" I'm around here, and I'll come to collect it in half an hour! Liang Zichen hung up the phone immediately after saying this viciously.
