Old John frowned: "It's equivalent to the rats in the entire village. Why would the rats in the entire village come here at this time?

"According to what you said, these rats cannot live in the room forever, cannot be fed, cannot eat, and cannot be hidden.

"Then it can only come from the outside during this period, and the door is closed now. The room you want to enter can only enter Ruan Xing's home through the sewer and toilet as mentioned before.

"Isn't this a little too weird? Dozens of rats seem to have made an appointment to gather here together through this abnormal road. It's too unnatural."

"No."

Zhang Lingjun shook his head and said: "It's just that the number of rats is equivalent to the number of the entire village. It doesn't necessarily need to attract all the rats in the entire village.

"In fact, rats in cities are more common than you think.

"The environments where there may be a large number of rats mentioned by Officer Gang Hei are all places within the scope of human activities. In addition, there are also some places that humans rarely set foot in and subconsciously ignore.

"For example, underground.

"Every modern industrial city has a huge and complex underground city that is completely opposite to the surface. Countless space pipes form an extremely complex system, which is deeply inserted into the underground and intertwined to maintain the metabolism of the city.

"It's like the crown and root system of a tree. The thicker the crown, the deeper the roots will take root.

"This is the basis for the city to maintain cleanliness on the surface. All the filthiness is borne by the sewer system buried underground.

"Countless domestic garbage flows in it, rotting, damp, and dark. This is a natural breeding ground for rats.

"Countless rats breed in it, let alone dozens, as many as you want.

"In fact, the mice that usually get into the room from the toilet come from this. After all, for convenience, the sewers are connected to every household.

"The origin of the rats is not the issue.

"Of course it's just the source. The strange and abnormal appearance of so many rats still cannot be explained.

"If it were a mouse, then it would be fair to say - Ruan Xing doesn't bring food home every night, and often flushes the leftovers in the toilet. It is normal for him to attract mice. There is no way to explain why there are so many mice."

Old John asked: "Do you think it is related to the noise? The two appearances of the mouse were closely accompanied by the noise, so people can't help but think of it."

Rats, noise, headache...

Zhang Lingjun shook his head with a headache, "It may be related, but I can't figure out how. I don't know, I can't figure it out."

The black policeman said: "No matter how those disgusting creatures appeared? Are they natural or man-made? What we need to know now is whether Ruan Xing's death is related to this phenomenon?"

Zhang Lingjun shook his head, "Based on the current clues, it should have nothing to do with Ruan Xing's death, or there should be no direct connection.

"Although the appearance of so many rats is indeed strange and contrary to common sense, rats are just rats, and the greatest harm they can cause to a person is to make people very sick, and at most they can spread viruses.

"This has no necessary connection with the cause of Ruan Xing's death, nor can it constitute the cause of death..."

Old John said: "In other words, it is still useless information... Sigh... Why are there so many irrelevant interferences? What happened last night?"

The three of them looked at each other, shook their heads involuntarily, and sighed, their faces full of sadness.

I don’t know why, but the more we investigate the case, the more things develop and become more complicated.

The footsteps from before disappeared without a trace, and now there was a group of sewer rats coming uninvited, and there were more and more weird things happening.

If you want to solve these mysteries, the only thing you can do now is to continue going down.

Audio 9.

Interception time 23:05, duration 1 minute.

After the audio is turned on, there is still a sharp noise, which penetrates deeply into the soul.

Zhang Lingjun felt the pain, and could feel the extreme resentment he seemed to harbor.

More ferocious than a lion, and more sinister than a poisonous snake, it seems to be a collection of all barbaric, evil, and sinful sounds.

Sometimes the black policeman next to him smiles sinisterly and turns into Old John again, suddenly becoming himself again.

It is different from before. It seems that every time I listen to this sound, I have a different feeling, but the same thing is that it can be related to myself every time, and it also makes people feel extremely uncomfortable.

It is a very strange, instinctive discomfort that seems to be born from genes and souls.

After the ear-piercing noise, there was a pitiful howl that was almost noise and contained infinite pain.

All three people could clearly hear that it was a human female cry, which was very similar to Ruan Xing's voice.

Listening to this voice, Ruan Xing seemed to be suddenly awakened by something and encountered an accident.

Zhang Lingjun quickly raised his ears and listened carefully, but Ruan Xing's voice stopped suddenly, as if what he just heard was just an illusion.

Immediately afterwards, the squeaking mouse sounded again in the room. It seemed that it was disturbed by the movements just now. It screamed more fiercely than ever before. It was excited and seemed to be in extreme pain.

Wailing, this sound covered everything and drowned everything...

I don’t know how long it took, but the rustling and falling sounds died down.

The world has returned to peace again.

After that there was no sound.

This ends the audio.

Old John hurriedly said: "The scream should represent Ruan Xing's murder. Combined with the time of death shown in the biochemical test of Ruan Xing's blood, the error at this time is not more than half an hour, which should be the time of Ruan Xing's death.

The last sound she made.

"Finally found it, hurry up and see if there are any other clues related to it..."

Zhang Lingjun did not make any move.

Because the recording is all over.

Due to unknown reasons, the entire monitoring was completely suspended at this time, and nothing was included after that.

The surveillance video changed from darkness to blurry screen, and the recording also turned into noise.

I don’t know what kind of malfunction I encountered.

"No...is this the end?"

Old John was a little incoherent: "I only monitored this for a long time... what a hot chick..."

The black policeman frowned and said: "The surveillance system just happened to malfunction at the critical moment. This is really abnormal. It doesn't look like an accident. Was it that the surveillance system was discovered and the murderer dealt with it?"

Zhang Lingjun shook his head, "I don't know, it's not important. This is already the case. What we need to consider next is how to find the murderer from these surveillance cameras? How to solve the case?"

"Finding the murderer from surveillance? Solving the case? What a joke..."
