Police station.

How much do you remember about what happened at the scene?

Xiao He sat in the chair and recalled seriously: "There was a lot of smoke at the time, and there was a lot of blood and black ash on the ground... Cheng Hongwen fell to the ground, and I could hardly see anything else. I gestured to the brothers who were rescuing people, and then I carried him out."

Although the fire in the hotel room was extinguished in time, the fire and the sprayed water destroyed many traces and even made a mess of the scene. As a result, the situation at the scene after the murder was known only to Xiao He and Cheng Bei, who broke in.

At that time, the air was thick with smoke and the temperature was high. If he hadn't been wrapped in a fire blanket, Xiao He might have been burned.

The situation at the scene was a complete mess, let alone anything that could be noticed...

Wait, that's not right.

He may have noticed it, but it's hidden in his subconscious, and he can't recall it now.

Xiao He thought of something.

——Memory Retrograde Capsules!

[Memory Recall Capsule Details: A memorable first crime scene, remembered no matter how much time has passed—it can even help you recall the details of the crime, allowing you to craft more perfect lies and testimonies.]

Xiao He had drawn out several of these items before, but they had never been of any use and had been forgotten by him.

He had previously analyzed that this thing actually enhances memory, allowing people to recall certain details in their memory that might have been overlooked in a short period of time.

But these things are basically useless; in fact, they're becoming increasingly rare. Xiao He is reluctant to use his points to draw such useless items, so he's hoarding them all for his ultimate rat attribute burst.

This time it will come in handy.

However, the capsule was originally intended to allow Xiao He to revisit his own crime scenes and escape legal punishment. Now, Xiao He wants to use it to revisit other people's crime scenes and try to find some important clues to catch the murderer.

Ahem, although its usefulness seems to have shifted slightly, but... as long as it works!

Xiao He decisively used a memory reversal capsule and then closed his eyes.

At that moment, he felt as if he had returned to the scene of the fire.

Bloody footprints on the ground, black ash on the walls, a person lying on the floor, flames burning on the sofa...

Xiao He raised his head and his gaze fell on the curtains opposite him.

Behind the curtains, the windowpane was slightly ajar, and a faint bloody footprint remained in that spot. However, it was quickly covered by the flames from the burning curtains, and the black charred remains of the burned curtains quietly concealed the traces of its existence.

Xiao He squatted down again, his gaze falling on the burning sofa, examining it carefully.

Although the thick smoke from the fire obscured most of his vision, the smoke in his memory did not irritate his eyes. So, upon closer inspection, Xiao He discovered that the main thing burning on the sofa was a laptop.

Unfortunately, what he is seeing now is basically what the police can investigate.

For example, footprints on the window.

The fact that the hotel room door was sealed with a wet towel indicates that the murderer did not leave through the main entrance. Therefore, the only possible way out of the entire hotel was through the window—not that the murderer jumped directly out of the window, but rather climbed over the edge of the window to the next room.

The scene was chaotic. People from several surrounding rooms came out to check the situation and quickly moved away from their rooms. The murderer only needed to change his/her clothes or simply put on a bathrobe after the people in the next room left, making the appearance of a hotel guest, so that he/she could walk out of the room openly and leave the scene.

The police only need to compare and verify the surveillance footage and hotel check-in information one by one to be able to identify the target murderer.

The source of the fire is even easier to investigate. The fire department can provide a certificate of responsibility, clearly reporting the source and cause of the fire, without even needing the police to investigate.

What other help can he offer?

Xiao He circled around several times, looking at every nook and cranny, but found nothing new.

Xiao He was somewhat disappointed.

It seems he didn't see any useful clues at the time.

Xiao He was about to exit his memory palace when his gaze suddenly sharpened and fell on Cheng Hongwen on the ground.
