A perfect crime? To me, it's full of flaws!

Qi Feng opened his eyes. The world had changed.

The originally dark and dilapidated factory building was now covered with a faint glow in his eyes.

The data stream at the edge of the field of view refreshes rapidly. The gaze sweeps across the ground, walls, and abandoned machinery.

Three pale red squares slowly emerged in the corner.

Pale red, all pale red.

This color is what the system considers a non-critical clue.

Qi Feng curled his lip. Even a fly's leg is meat.

He took out latex gloves from his pocket, put them on, and walked straight to the first red box. It was the bottom of a rusty cutting machine.

Qi Feng squatted down, took out a flashlight for illumination, and carefully picked up an extremely thin black fiber with tweezers. He placed it into an evidence bag.

Xiao Liu was stunned as he followed behind.

The forensic team searched for two hours with multi-band light sources, but couldn't find a single hair. This person came in and went straight to the corner?

Qi Feng ignored her and turned to walk towards the second red box. It was a tiny scratch about ten centimeters from the ground at the corner of the wall. He took out his phone, turned on macro mode to take a picture, and used a ruler to pinpoint the location.

The third red box is located three meters away from the center of the bloodstain, on the edge of a sewer drain strainer. Qi Feng scraped off a tiny amount of barely perceptible white powder and poured it into another evidence bag.

"Advisor Qi, what are these?" Xiao Liu couldn't help but ask.

"The fibers are most likely from the raincoat the killer was wearing. The scratches are from the weapon accidentally hitting the victim. As for the powder, we'll have to send it back for testing to find out." Qi Feng stood up and clapped his hands.

He stood in the center of the factory, eyes closed. His mind raced. Gong Jianping's words, "psychopath," echoed in his head.

Profiling begins.

Female. Approximately 1.7 meters tall. Left-handed knife. Decisive movements, fatal with a single stab. Used a large amount of bleach to clean up the scene. Demonstrates exceptional mental fortitude; did not flee immediately after the murder, but instead methodically and systematically destroyed the crime scene.

Fragments of information kept colliding in my mind, trying to piece together a complete human figure. But the information left at the scene was too fragmented. The figure remained blurry. There was no core motive, no key physical evidence.

"Not enough." Qi Feng opened his eyes, his gaze icy. "Let's go to the second scene."

The second crime scene was located in an urban village.

A rented room of less than 20 square meters. The air was filled with a strange smell, a mixture of cheap air freshener and a faint stench of blood. Flies hovered over the ceiling.

Qi Feng crossed the warning line. The view opened up again.

There were no red borders inside the room; the trace evidence examination was done very thoroughly this time.

Suddenly, in the lower right corner of my vision, a huge, deep red box began flashing wildly. It wasn't inside the house, but at the end of the corridor outside the door.

Qi Feng turned and walked out of the house, quickly heading towards the area framed in red.

It was an open drainage ditch, covered with thick cement slabs. Dark green moss grew in the cracks between the slabs, emitting a foul stench.

"Advisor Qi, we've checked the outside as well," Xiao Liu followed closely. "We even checked the sewers with an endoscope, but there was nothing there. The suspect has extremely strong counter-surveillance awareness."

Qi Feng ignored him. He crouched down and gripped the edge of the stone slab with both hands. His arm muscles tensed instantly, and veins bulged.

"rise!"

The heavy cement slabs were overturned and crashed heavily to the side.

The stench of silt hit us.

Qi Feng stared at the bottom of the canal. Xiao Liu followed his gaze and instantly gasped, covering his mouth tightly.

In the murky sewage, a swollen, whitish strip of material hung from a piece of rusty wire.

An infant's umbilical cord.

"This...how is this possible?" Xiao Liu's voice trembled. "We checked three times..."

Qi Feng's eyes narrowed.

"Horizon Retrospection".

The world before my eyes instantly faded, turning into the yellowed, worn-out texture of old film.

In the video, a woman wearing a large black raincoat is squatting on the ground. Her back is to the camera. She is holding a stiff-bristled black brush and is vigorously scrubbing the blood off the ground.

The sound of the ground scraping was monotonous and grating.

The water, mixed with a dark red liquid, was pushed into the drainage ditch. The umbilical cord rolled down with the current and got caught on a wire, where it was firmly hooked by debris.

The camera angle shifts slightly. Beside the woman's feet lies a black plastic bag. The bag is bulging.

Next to the plastic bag lay a single-edged knife. The blade was stained with blood, and the handle was wrapped with black electrical tape.

The scene abruptly ended. The world returned to color.

Qi Feng rubbed his throbbing temples. Rewinding was exhausting.

"Has the child not been found?" Qi Feng turned to look at Xiao Liu. His tone left no room for argument.

Xiao Liu paused for a moment, then quickly replied, "Yes...yes. After the incident, we searched the surrounding area but didn't find the dissected infant corpses. We didn't even find any embryonic tissue."

"Come with me." Qi Feng stood up and strode outside.

At the entrance of the alley, there is a small supermarket with its sign lit up.

"This is the direction the suspect left in, right?" Qi Feng stopped in his tracks.

Xiao Liu opened his notebook: "Yes. After she left this alley, the surveillance cameras outside never captured any more images of the suspect. She completely disappeared."

Qi Feng sneered.

No one can disappear. Every step leaves a trace.

He activated his skill again.

In his field of vision, some light red prompt boxes began to appear. Some were closer to Qi Feng, while others were much farther away. These were all traces left by the suspect. The suspect had overlooked this place. He didn't know why, but she left her mark along the way. Perhaps it was because it rained that night, or perhaps it was because she was unsettled. But this gave Qi Feng an opportunity.

Qi Feng followed the instructions and walked forward.

Turn east, then west. Pass through two narrow alleys.

Ahead was a half-collapsed brick wall.

Qi Feng easily flipped over with one hand.

It landed silently.

Walk through a rubble awaiting demolition. Avoid the shards of glass and steel bars scattered everywhere.

The movements were fluid and seamless, without the slightest pause.

Xiao Liu was panting heavily as he ran behind.

She stared in shock at the incredibly fast-moving figure ahead of her.

Is this person really a civilian consultant for the provincial department?

His skills are even better than the assault team members in the brigade! And what exactly is he tracking? The air?

Ten minutes later.

Qi Feng stopped in his tracks.

Ahead was a large construction site. Around the perimeter of the site was a huge green construction waste bin.

In my field of vision, a huge, deep red square completely enveloped the entire trash can. The red light was blinding.

The footprints disappeared completely here.

"Consultant Qi... Consultant Qi." Little Liu caught up, panting, hands on his knees. "Why did you stop?"

Qi Feng ignored the surprised looks behind him. He took two steps back and then suddenly accelerated.

He pushed off the outside of the trash can with his right foot, using the momentum to lift himself into the air. He grabbed the edge with both hands and flipped himself inside.

"Oh no! Danger!" Xiao Liu exclaimed and rushed over.

The trash can was filled with broken planks, broken bricks, and discarded woven bags.

It emitted a pungent smell of formaldehyde and mold.

Qi Feng knelt on the pile of waste.

He pried off the heavy cement slabs covering the surface with his bare hands and tore off a layer of tattered dustproof netting.

Under the dustproof netting, there was a black plastic bag.

It's exactly the same as the one in the flashback footage.

The only difference was that the garbage bag was now deflated; the contents were gone, leaving only bloodstains and some skin tissue.

It seems that the suspect, upon arriving here, discovered that the bag he had used to contain the baby's body had a small tear, so he discarded it here and then took the body away with something else.

Why did she take the body away?

Qi Feng stood there, his mind racing, piecing together everything from the crime scene in his head.
