When ye Fei saw the dust everywhere under his feet, he knew that no one had come up recently. But that voice never disappeared in his ear, and it seemed to be clearer than just now.

He asked Qin Guang, "have you ever checked inside? You should have been more careful at that time."

Qin Guang replied: "after all, the owner of the house, Guo Jucai, is determined according to the fact that he died in a traffic accident. Therefore, we won't do that kind of investigation on the house, and there are no footprints left on the dust on the ground. Of course, we don't need to do more."

Ye Fei thought about it. From a normal point of view, it's not a murder after all. It's not a waste of manpower to dig three feet into the house because of the complaint from the next door neighbor.

"Well, is the sound you heard your illusion?"

"I don't think so!" Ye Fei said very definitely, although he couldn't get any conclusive evidence.

Qin Guang simply stretched out his hand, pointed to the inside and said, "since we've all come, we might as well go in and have a look. It's not bad for these minutes. It's also good to let you dispel this doubt."

Even if Qin Guang didn't say so, ye Fei was really ready to look inside. Although he might not find anything suspicious, he wouldn't be at ease if he didn't confirm it with his own eyes.

They then walked inside. Ye Fei only felt that he was breathing here, and the air was full of countless dust. In addition, he didn't find anything.

But at this time, he heard the voice again, and this time it was particularly clear, which made Ye Fei completely convinced that it was not his illusion.

"Just now it came again!" Ye Fei murmured to himself.

Qin Guang was still confused. He had always been sensitive. In the past, when performing tasks, the partition wall could know how many criminals there were by virtue of the footsteps in the room.

But today, at this moment, he even suspected that he was completely deaf, because even if ye Fei reminded him several times, he still didn't hear any sound.

"If you weren't joking, I might have suddenly lost my hearing."

Ye Fei gave him a white look. "Then how can you hear me? I think this voice should not be from the normal outside world, but from another world, so you don't feel anything about it."

"Don't talk. Let me listen carefully. I think we're almost close to the answer."

Qin Guang was a little helpless. He was the leading role in the investigation of the case, but now he had to follow the instructions of the young man. This role change really made him feel a little uncomfortable.

Ye Fei no longer spoke, but walked slowly to the dark room step by step. Qin Guang tried to find the lighting switch, but found that this floor was not powered on and all lamps could not be lit.

He had to take out his mobile phone and turn on the lighting function. The room in front of him was empty without any home furnishings. For Guo Jucai, who lived alone, this floor was indeed redundant and could not be used at all.

Suddenly, ye Fei quickly walked towards the window. His expression looked a little urgent. It seemed that he had found something worthy of attention and was making further confirmation.

But for Qin Guang, this is a very painful few minutes. He has always been good at insight. He is expected to wait quietly for ye Fei to explain, but it seems that they should have gained something.

"It's strange that the sound seems to be in this room, but I can't find the source of any sound at all."

Qin Guang thought for a moment. This sentence seems to be contradictory, "how can I not understand? Since you are sure you heard that voice, how can you not find the source? All voices have a source."

Ye Fei closed his eyes and seemed to be thinking about something. He naturally understood what Qin Guang said, but it was so strange in front of him. He clearly heard that the voice was very close to them, mostly in this room, but he didn't find anything.

"No, maybe I ignored something. Let's find out if there is a compartment in this room, maybe a secret room."

Qin Guang looked at Ye Fei and said, "I hope your judgment is right."

At Ye Fei's insistence, Qin Guang cooperated with him to search together. He was confident that there was absolutely no secret space in the two floors below the house, but he was not sure about the third floor.

But no matter how clever the secret room is, in the view of the experienced Qin Guang, it is hard to escape his eyes. As long as this space does exist, it doesn't take him much time to find it.

Ye Fei only put forward such a possible hypothesis, but he was not sure whether there was a secret room. It can only be said that this is a reasonable explanation. If this explanation is not tenable, it can at least eliminate wrong judgment.

Five minutes passed quickly. Ye Fei and Qin Guang had made a detailed investigation of all the places that might hide the secret room, but they found nothing.

"It seems that your judgment is not tenable. I have been in this business for so many years. If there is a secret room, I will definitely find it."

Just when Qin Guang lost some confidence in Ye Fei, the latter was suddenly stunned.

"Don't be paranoid. I think you are too sensitive. You might as well go back and have a good rest, and then think about how to catch that woman."

However, ye Fei did not pay attention to him, but suddenly walked quickly to the window and completely opened the upper hanging window that had been closed for a long time. He moved very quickly, as if he was catching something, but Qin Guang still didn't find anything.

"The foreign houses here are so close to each other."

Ye Fei looked at the scene outside the window and turned to Qin Guang.

"Oh, you say this. Because this is an old city, old-fashioned foreign houses like this have been for some years. At that time, the layout was like this. The two families were very close to each other."

"Oh, what are you doing?"

Qin Guangzheng was talking, but he saw Ye Fei jump gently and wanted to climb out of the window. He always had such unexpected strange behavior, which made Qin Guang's reaction always unable to catch up.

Ye Fei explained, "I think the sound came here from the next door, so I'm going to have a look."

Qin Guang immediately stopped and said, "this is called breaking into private houses. It's not appropriate to do this kind of thing, and it's in front of me."

"If someone finds out, it's called breaking into a private house. What if they don't find it? Don't worry, I'm so good. I'll be imperceptible."

Ye Feichong and Qin Guang waved their hands without taking what they were doing to heart. Although Qin Guang also wanted to thoroughly find out what happened here, he had no choice but to stay where he was because of his identity as an inspector.

"Inspector Qin, just stay here. I'll go and come back soon."
