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

"Hold on tight." Qi Feng floored the accelerator.

The AMG G63's V8 engine roared low as the black SUV swerved into the road at an intersection, its tires screeching as it sped toward the west of the city.

Liu Yuanshan was slammed back in his chair by the inertia, his face pale: "You little brat, are you flying a fighter jet?!"

Lin Haitang clung tightly to the survey kit, gritting her teeth and remaining silent.

Three police tapes were set up outside the main gate of the amusement park in the west of the city. Several police cars were parked on the roadside with their red and blue lights flashing.

Qi Feng slammed on the brakes and brought the car to a stop. Liu Yuanshan opened the car door and, leaning against it, gagged.

"Master, you still need to work on your composure." Qi Feng handed over a bottle of mineral water.

Liu Yuanshan slapped his hand away: "Get back to work!"

A tall man with deep-set eyes strode over. He wore a wrinkled jacket and had a full stubble of bluish beard.

"Master. Haitang." Qin An's voice was hoarse, filled with deep exhaustion. He turned to look at Qi Feng, "Junior Brother is here too."

"Senior Brother, how's the situation?" Qi Feng put away his nonchalant expression.

Qin An led the three of them inside. The amusement park was overgrown with weeds, and the rusty rides looked dilapidated on the cloudy day.

"Over there on the carousel. The fourth ride," Qin An pointed ahead. "It was discovered by tourists at night, and the video was uploaded online."

"The deceased was a woman, and her identity is still being confirmed. Her characteristics are consistent with the previous three cases. There were no valuable footprints or fingerprints at the scene. We'll have to wait until the forensic team finishes their work before we can investigate the contents of the doll."

Qi Feng walked to the carousel. A huge brown bear plush toy lay slumped beside it, its back zipper open, and a forensic doctor was conducting a preliminary autopsy. A faint, fishy stench filled the air.

Qi Feng took a deep breath and focused his attention.

His perspective shifted instantly. The colors of the entire world faded, and everything was deconstructed in his eyes.

No.

There was nothing on the doll, and nothing around the corpse.

Qi Feng's gaze swept across the perimeter. Suddenly, on the edge of the carousel's canopy, on a rusty iron pillar, a red square the size of a fingernail appeared.

He walked over without making a sound.

"Don't run around and disturb the scene," Qin An warned.

"I'll just take a look." Qi Feng stopped in front of the iron pillar. The red frame was locked onto the rusty gap about 1.6 meters above the ground.

He leaned closer and squinted. A very fine black fiber was stuck in the gap.

"Senior Brother, did you bring tweezers?" Qi Feng called out.

Qin An walked over and looked in the direction Qi Feng was pointing. He frowned slightly, took out an evidence bag and tweezers from his pocket, and carefully picked out the strand of fiber.

"It's made of synthetic fibers, like the fabric of some kind of waterproof windbreaker." Qin An held up the evidence bag, glanced at Qi Feng, and asked, "How did you find out?"

"My eyesight is good, 5.2, but with so many people coming and going, I can't be sure if it was left by the murderer." Qi Feng grinned. He knew it must have been left by the murderer, otherwise the system wouldn't have given him a notification, but he couldn't say it out loud.

Liu Yuanshan walked over and glanced at the evidence bag: "It's too subtle. It's very likely that the murderer's clothes grazed the iron pillar when he disposed of the body. Qin An, send it for testing immediately."

"Yes." Qin An nodded. "The technical department is retrieving surveillance footage from a three-kilometer radius around the amusement park. Master, the re-examination of the first three scenes..."

"Let's go now," Liu Yuanshan interrupted him. "Leave some people at the amusement park to monitor the surveillance. You take us to the first three crime scenes. I want to see if this killer can really disappear."

The two cars left the amusement park one after the other.

First scene, Chengnan Coffee Shop.

Qi Feng stood by a chair outside the coffee shop, his eyes wide as he scanned the area.

Everything in sight was clean and tidy.

S City had two heavy rainstorms a few days ago, washing the area clean. Qi Feng rubbed his sore eyes, cursing inwardly.

The second location is at the end of the popular commercial street.

The crowds were immense. Even though there were warning lines in place, they had long been trampled flat by internet celebrities and tourists.

Qi Feng activated his ability and spun around for ten minutes, but found nothing except cigarette butts and milk tea cups scattered all over the ground.

"Go to the third scene." Liu Yuanshan's expression grew increasingly grim.

The back alley of a large shopping mall, the receiving area.

This place is perpetually dark, and the air is thick with the smell of damp cardboard boxes and sewers. Several loaders push their carts back and forth, leaving messy tire tracks and footprints on the ground.

"The doll was right there in that corner," Qin An said, pointing to a pile of discarded cardboard boxes. "That's a blind spot for the security cameras. The mall staff thought it was left behind by a store after receiving a shipment, and only called the police when they smelled something strange."

Liu Yuanshan crouched down and carefully examined the ground. Qin An assisted him from the side.

Lin Haitang took notes with a tablet.

Qi Feng put his hands in his pockets and slowly walked out of the alley.

"Xiao Qi, don't go too far," Lin Haitang called out.

"I'm looking for inspiration," Qi Feng said without turning his head.

He walked to the alley entrance, where several large trash cans were piled up. It was a small garbage station set up by the shopping mall for its merchants.

Qi Feng habitually activated his ability.

My vision snapped open.

A huge red box appeared out of nowhere, completely enclosing an object behind the trash can.

Qi Feng strode over and kicked aside several broken cardboard boxes blocking his way.

A supermarket shopping cart was visible. The wheels were rusty, the basket was deformed, and it was covered in dust and grime.

The red frame highlights this handcart.

"Master! Eldest Brother!" Qi Feng turned around and shouted.

Liu Yuanshan and Qin An walked over quickly.

"What's wrong?" Qin An asked.

"This shopping cart is interesting," Qi Feng said, pointing to it. "The mall's receiving area has special hydraulic carts and flatbed carts. Who would use this kind of small supermarket cart here?"

Qin An squatted down, put on gloves, and carefully inspected the handcart.

"The wheels have fresh wear marks, and there are several indentations on the bottom of the basket." Qin An looked up. "It was recently used and carried heavy loads."

Liu Yuanshan narrowed his eyes: "A large doll plus a female corpse weighs over a hundred pounds. It would be very difficult for the murderer to move it alone; he would need tools."

"This car cannot prove that it was used by the murderer," Lin Haitang questioned.

"So we need to find evidence." Qi Feng didn't stop; he looked out from the alley entrance.

The alleyway connects to the entrance to the shopping mall's underground parking lot. There is a gentle slope and a few steps at the entrance.

Qi Feng lifted his leg and walked towards the steps.

The red frame flashed again in my field of vision.

This time, the red frame was very small, only the size of a coin, and landed precisely on the cement ground at the edge of the steps.

Qi Feng walked to the steps and squatted down.

There was a tiny, dark brown patch in the crack of the cement floor.

"Senior Brother, did you bring the luminol reagent?" Qi Feng turned around.

Qin An immediately ran over with his survey kit. He took out a spray bottle and sprayed the edge of the steps.

A few seconds later, the dark brown patch began to glow faintly with a blue light.

Bloodstain reaction.

The scene fell silent instantly.

Liu Yuanshan strode down the steps, staring at the blue light with eyes as sharp as knives.

"The body was inside a doll, zipped up. The killer transported it by handcart." Qi Feng stood up, dusted off his hands, and said calmly, "When the handcart reached the steps, it encountered an obstacle, causing a violent jolt. The blood inside the doll was squeezed out, seeping through the zipper and dripping onto the steps."

Qin An immediately chimed in, "The murderer brought the body up from the parking lot! He had a car, and he parked it in the underground parking lot!"

Lin Haitang quickly operated the tablet: "The mall's underground parking lot has a complete surveillance system. We just need to check the time of the incident, the vehicles entering and leaving the parking lot, and the people carrying these shopping carts..."

"The range has been greatly reduced." Liu Yuanshan breathed a sigh of relief, and his gaze towards Qi Feng changed.

This kid usually seems unreliable, but once he gets to the scene, his eyes are incredibly sharp.

"Qin An, collect the bloodstains and do DNA testing to confirm if it's the third victim, Li Li," Liu Yuanshan ordered. "Haitang, contact the Municipal Public Security Bureau's Image Investigation Division and retrieve all surveillance footage from the mall's underground parking lot for the 24 hours before and after the incident. Focus on suspicious vehicles and people carrying shopping carts."

"Yes!" the two answered in unison.

Qi Feng stood there, still puzzled. The other three corpses were either in a popular internet celebrity street or an amusement park, places with high foot traffic. How come this one was at the warehouse entrance of a shopping mall?

Could it be that the psychological test that identifies me as the murderer is wrong?

Master Liu Yuanshan noticed Qi Feng's confusion.

"Have questions? Can't figure it out?"

"Um."

"Then keep investigating and find out everything you have in mind!"
