"You'd better adjust your attitude!"

Zhou Yong's fingers heavily tapped the tabletop, making a dull "thud thud" sound.

His voice exploded in the confined interrogation room, "This is not the time for clever tricks!"

Wang Yang followed with a slap on the table, making the notebook bounce, "We know far more than you imagine!"

However, facing the police's intense pressure, Qin Yong remained irritatingly calm.

He even leisurely adjusted the hem of his clothing before finally throwing out a line, "Arrest me if you have evidence, let me go if you don't."

This seemingly simple statement carried the sting of poisoned needles, piercing the two officers with anger.

Wang Yang stood up in a fury, almost poking the other one's nose with his finger, "I'm asking for the last time, where exactly were you on May 18th?"

Just as the confrontation reached its peak, the phone in Wang Yang's pocket suddenly vibrated.

Suppressing his anger, he answered the call, his gaze suddenly becoming sharp, "Okay, understood...."

Meanwhile, in the forensic lab, a precise race against time was underway.

Jiang An, wearing double layers of rubber gloves, carefully adjusted the position of the pelvic specimen.

The grinding task that had lasted for thirty minutes made his arms tremble slightly, with beads of sweat appearing on his forehead.

"Let me do it."

Wan took over the grinding rod, the sound of metal against bone creating an unnerving noise.

He grumbled as he forcefully turned the grinder, "What era are we in, still grinding by hand?"

"Buying an electric grinder off the market could increase efficiency by ten times."

Jiang An shook his arms, "Cut me some slack."

"Determining the death time of an ossified body is already a problem in the forensic field, and the method we're trying is a first in the nation."

"A first?"

Wan's hands suddenly paused, nearly dropping the grinding rod.

"You don't mean...this method isn't clinically validated yet?"

His voice suddenly rose by eight decibels, "All this work might be useless if we can't get results..."

Jiang An quickly walked over, the rubber soles of his shoes making a soft squeaking sound on the tile floor.

He patted Wan's shoulder reassuringly, "Big risks yield big rewards."

"If our results match the suspect's confession time, this could be a groundbreaking paper."

"This is a great innovative act, and you definitely deserve credit!"

Saying this, he turned towards Zhang Yean, who was recording the events.

"Remember to take several close-ups of Wan at work."

"When this technology gets patented, the lead lab technician's name position will be none other than him."

Zhang Yean understood and blinked, smiling as the camera focused on Wan's glove-covered in bone dust.

"Of course."

"Wan's 'three-point positioning grinding method' could be textbook material, I even recorded the whole process on video."

Upon hearing that, Wan suddenly felt the grinder in his hand grow lighter.

He grinned, the pain in his arm strangely disappearing, replaced by a sense of historical mission.

"If this really works..."

As he labored over the grinding process, he mused, "In future textbooks, it might be written: 'This method references the standard grinding workflow of Mr. Wan.' The Wang Family tree might just add a page for me!"

With that thought, he added more pressure, the sound in the lab becoming more rapid.

Meanwhile, in the data analysis office, four high-performance computers were running at full speed, emitting a faint hum.

Two forensic assistants and three technicians focused intently on the screens, fingers flying over the keyboards.

They were processing an extensive data table containing weather records from the past 60 months citywide.

"Double-check the data, we can't afford any mistakes."

Despite the daunting data volume, thanks to teamwork and efficient spreadsheet systems, they'd completed two-thirds of the workload within just two hours.

Everyone's monitors flashed the same data interface, any changes instantly synchronizing across all terminals.

Two hours and 15 minutes later, the abandoned parking lot on the outskirts was enveloped in dusk.

The first investigation team's police car rolled over the bumpy concrete road, finally stopping before a mottled wall.

The rusty iron gate swayed slightly in the autumn wind, emitting an unsettling "creak" like a foreboding warning.

Scene investigation expert Li Guang pushed open the iron gate, and the metal hinges screeched.

He squinted against the stinging sunset, with hundreds of scrapped cars parked haphazardly, some piled even into small mountains.

"Mr. Wang, we need to reconfirm the target vehicle's license plate."

As Li Guang took out his phone, he found his gloves already covered in the reddish-brown rust powder from the gate.

On the other end, the sound of papers shuffling came through, followed by Wang Yang stifled, angry voice: "Sichuan G7788."

In the background were the faint sounds of rapid typing, "Pay special attention to the chassis and front, the forensic team suspects there might still be residue there..."

The call was suddenly interrupted by a piercing static noise.

Li Guang frowned at the phone, which now showed only two bars of signal, turning to the fully armed six-member team behind him.

"The target vehicle's right headlight has repair marks. The inner side of the cargo door should have collision dents."

Li Guang's voice slightly echoed in the empty parking lot.

"According to the initial forensic examination, this likely involves a well-planned hit-and-run and body dump case."

"Chen, record all biological traces on the vehicle's surface. Mr. Zhao, focus on photographing the chassis..."

"Commence the operation!"

The team members nodded silently, the sound of rubber soles scraping the ground strikingly clear in the silence.

Someone retrieved evidence bags marked with fluorescent labels, while others adjusted the focus of their UV lamps.

Six beams of flashlight pierced the twilight like searchlights.

Li Guang crouched by the target vehicle, his fingers lightly touching the cobweb-like cracks on the hood.

Suddenly, a peculiar reflection caught his attention — inside the right front wheel's mudguard, several fingernail-sized transparent shards gleamed faintly.

Meanwhile, 40 kilometers away in the forensic lab.

Jiang An finally completed the bone sample grinding task.

His lab coat was covered in tiny bone dust, with fine beads of sweat seeping from his forehead.

"Sister, the grinding here is done, please give me a slide."

He extended his hand without looking up, his voice slightly hoarse from prolonged focus.

"So soon?"

Zhang Yean raised an eyebrow in surprise, taking a clean slide from the sterilization cabinet.

"Are you sure the grinding is fine enough? Accuracy matters for testing."

Beside him, Wan rubbed his sore wrist, smiling bitterly, "Sister, you call this quick?"

"My right hand's about to go numb."

The sleeves of his lab coat were soaked with sweat.

Jiang An took the slide, carefully picking up a small amount of the bone dust sample with tweezers.

His movements were as precise as conducting microsurgery, meticulously controlling his breathing.

"Brother, once this case is solved, I'll treat everyone to dinner."

As he spoke, he dripped a specially formulated chemical reagent, creating a slight fizz when it made contact with the bone dust.

When Jiang An placed the slide under the microscope, the entire lab's atmosphere seemed to freeze.

Zhang Yean and Wan instinctively held their breath, leaning in to observe.

The microscope's cold light cast a strange blue glow on Jiang An's face, his pupils contracting and expanding with the image in the eyepiece.

"Time to witness a miracle..."

Wan whispered, his voice filled with anticipation and tension.

Zhang Yean unconsciously bit her lower lip, her fingers tightly gripping the edge of the lab table.

At this moment, Jiang An was completely absorbed, as if he'd forgotten everything around him....
