"And our goal is to find the murderer.

"The problem is that the murder scene and surveillance have not found any traces pointing to the presence of the murderer.

"But killing will definitely leave traces.

"So what we have to do is to find out the possible clues left by the murderer that may have been ignored from the information we have learned so far.

"First we need to find out the murderer's movement trajectory and how he committed the crime.

"How did the murderer enter the room?

"How to enter the room without being discovered?

"How to kill people next?

"How to leave in the end?

"And the strange sounds coming from Ruan Xing's room, the abnormal gathering of mice, the sound of footsteps stopping at the door, and the room full of people learning numbers. What are these fragmentary clues about?

"Then get effective information about the murderer from it."

Zhang Lingjun asked: "So how did the murderer enter the room in the first place?"

The black policeman said: "Our previous guess was that it was after the last scream, but now based on these clues, there is no time after the scream, only before the sound.

"The most likely time before the sound occurs is while sleeping, but because of your behavior on the way home, Ruan Xing last night was prepared for the possibility of someone attacking at night. Compared to

In the past, the door to her house was closed very firmly today and locked several times.

"It is impossible for the murderer to secretly open the door and sneak in after sleeping.

"Before turning off the lights, the entire gate was under surveillance, and we didn't notice it.

"That is to say, there was no sign of anyone entering Ruan Xing's room from outside last night.

"No one entered from the outside, but something happened inside the house. People inside died. There are only two possibilities. One is that the house is haunted, and the other is that there is someone hiding in the house.

"Comed in earlier.

"Aside from Ruan Xing, there is actually another person hidden in that room, the murderer."

Zhang Lingjun nodded, "In such a small rental house, you can see everything at a glance, and the layout is also simple. There are only two places where you can hide, one is in the cabinet..."

"Well... this can be ruled out. Ruan Xing took the clothes from the cabinet while taking a shower. If he hid them in the cabinet, he would definitely be discovered."

The black policeman continued: "Other than that, the only thing left is under the bed."

"Under the bed..."

Old John frowned when he heard this: "It's possible to hide in this place, but I remember that after Ruan Xing returned home, except for eating and bathing, he basically lay on the bed and played with his mobile phone. It can be said that there is only a wooden board between him and the murderer.

There is no real discovery at all?

"You must know that Ruan Xing is not the kind of person with dull senses. She is also gifted in perception, otherwise she would not have discovered your tracking early."

Zhang Lingjun said: "Maybe it's because Ruan Xing didn't concentrate on this aspect, and the murderer took advantage of this."

"What do you mean?"

Zhang Lingjun explained: "Although our human perception system is like a super radar, it is sensing the surrounding external environment all the time.

"But not all the information perceived will be analyzed by consciousness. The brain's ability to process information is limited. In order not to overwhelm itself, it will automatically filter some information.

"To turn the perceived information into consciousness requires attention - you may have also experienced that sometimes you are very sensitive to certain sounds and can detect very subtle sounds, and sometimes you are very slow to certain sounds, just like

It's like being deaf.

"As long as the murderer is careful at the beginning so that Ruan Xing doesn't notice anything is wrong, he will not be discovered by her even if he hides around her without making any obvious movements."

Old John thought for a while and said doubtfully: "But people are not corpses. How can there be no obvious movement? They always have to move their bodies and breathe. They are so close. It is impossible to hear these sounds.

, it is very likely to attract attention."

Zhang Lingjun shook his head: "The formation of attention essentially has nothing to do with sound. Attention is related to the environment or people's memory.

"If people want to focus on a certain sound, they need to remember to make it special, and then their consciousness will adjust it. For some information that is too ordinary, they will subconsciously ignore it.

"After a busy day, a person returns to memory and is associated with safety and rest. It represents a spiritual harbor and a home where the spirit can relax.

"The door lock represents isolation between the inside and outside, and represents safety without any abnormalities.

"After entering the door, if nothing unexpected happens, I will just follow my past habits and planned steps, and perform rituals that seem to be inevitable, and I will avoid concentration.

"Naturally, even if you hear some small movements, you will subconsciously ignore them... um..."

As Zhang Lingjun said this, he couldn't help but think about himself, and the strange feeling he had after Ruan Xing fell asleep when he was listening to the recording before - the feeling Ruan Xing gave people after he fell asleep.

The feeling suddenly seemed to disappear. The person did not disappear, but the feeling disappeared. I suddenly figured out what was going on.

Then he didn't care about the two people who were waiting for him to respond after he finished speaking.

Zhang Lingjun quickly tapped the keyboard, turned on the monitor again, and started playing again.

When Ruan Xing just returned home, as the figure appeared on the video, the chaotic sounds fell into his ears and turned into a clearly visible message that a person was returning home normally.

But apart from that, the strange thing is that a very faint breathing sound can also be heard.

It's not the kind of violent breathing, it's just a person's normal breathing.

Under normal circumstances, Zhang Lingjun cannot hear Ruan Xing's natural breathing in the recording, because such a small sound cannot be recorded unless she is very close to the microphone, but now she is clearly still at the door.

Drag the progress bar to reach the limit when Ruan Xing actually falls asleep, and feel that the world in the recording begins to become different.

Zhang Lingjun concentrated his attention and listened carefully. No matter whether it was before or after the moment of falling asleep, the sound of breathing did not change at all.

His face couldn't help but reveal that it was indeed the case, and he dragged the progress bar to the end.

Just listening to the last recording, Ruan Xing seemed to have suffered an accident. When he woke up screaming, and after he completely lost his mobility, his weird breathing also did not end.

An extra breath!

This is why it feels like Ruan Xing suddenly disappeared after sleeping, but yet feels that he still exists.

There was still a person hiding in the room at that time, the murderer secretly hiding under the bed.

As for why there is no attention?

Zhang Lingjun was thinking.

It should also be because of memory, but it is not because, as mentioned before, Ruan Xing was disturbed by family-related memories, his consciousness affected his attention, and his perception was weak, so he did not notice the murderer hiding around him.
