Lu Chuan's age looks just past twenty.

Being so young and yet part of a special task force set up by the provincial office, Wang Hao, being a seasoned individual, naturally assumed that there was someone backing him.

Otherwise, Liu Guodong from Haizhou City's Crime Scene Investigation, whom he knows, didn't get in, despite both having participated in the provincial fingerprint match, tying for last place.

Of course, there were more than just them tying for last place; usually, there are about seven or eight people.

After all, not everyone can successfully match fingerprints in every match.

It requires luck and even more so, skill.

Liu Guodong from Haizhou's Criminal Investigation Team didn't join the task force, but the young detective Lu Chuan did.

What does this imply? Wang Hao naturally had his guesses.

However, it had nothing to do with him.

Especially since Lu Chuan picked up the basic task of crime scene photography, Wang Hao's perception improved greatly.

No matter how he got into the task force, if the person has the eye to see things and respects seniors, he's a good comrade.

But as he continued, Wang Hao realized something was off.

The crime scene photography Lu Chuan conducted was extremely standard, with points selected perfectly; all markings needed no guidance, and everything was in perfect order.

This was not the performance of a young crime scene investigator.

Later on, Wang Hao felt a stark contrast.

Lu Chuan had changed cameras twenty minutes ago.

Wang Hao recognized it, as Binzhou's Criminal Investigation Team's crime scene office also had one.

A fingerprint camera.

Unlike a regular camera, a fingerprint camera is designed specifically for criminal investigation departments.

There are many types of fingerprint cameras; their common features include fixed focal lengths, precise 1:1 shooting systems, and built-in illumination devices.

Fingerprint cameras are easy to operate and flexible to use, but their usage is not widespread because of their high cost, so normal cameras are mostly used for photographing fingerprints.

Wang Hao wasn't surprised that Lu Chuan could produce or use a fingerprint camera.

He was surprised by the fingerprint collection Lu Chuan was doing. If he wasn't mistaken, Lu Chuan was collecting fingerprints from a rubber glove he retrieved from the trash bin.

He had just checked; the entire operating room was very "clean."

The operating table, shadowless lamp, floor, surgical instruments, etc.

He had observed every possible place and found no valuable fingerprints.

The few there were all smudges, with no collection value.

Collecting fingerprints from rubber gloves was something Wang Hao never considered.

It's not feasible.

But Lu Chuan not only did it but also explained it to him.

Binzhou City's economic development is similar to Haizhou, if not slightly behind.

Thus, Binzhou's Criminal Investigation Team covers both crime scene and trace inspection, using one team for dual tasks.

Wang Hao also works dual roles in crime scene and trace inspection and was quite impressed by Lu Chuan, a young, newly graduated and capable junior colleague.

Lu Chuan didn't have as many thoughts as Wang Hao; this basement-converted operating room was clearly the "primary crime scene."

Although the other party cleaned the operating room after the "operation," many traces couldn't be erased simply with water.

Advanced fingerprint identification analysis gave Lu Chuan more than just capabilities in fingerprint identification alone.

For instance, in processing fingerprint images, Lu Chuan could apply this not only to fingerprints but to other evidence analysis as well.

"Brother Wang," Lu Chuan wasn't polite, with a basement over a hundred square meters, doing the crime scene investigation alone was too much for him.

Wang Hao was just right to help: "Even though the other party cleaned the operating table, instruments, and shadowless lamps, they left some smudged fingerprints, and there were remnants in the floor gaps, tile joints, sewer inlets, and other places."

"Here, I'll handle fingerprint wiping, you help me with the fluorescent light."

Wang Hao naturally took the fluorescent light from Lu Chuan, shining it on the edge of the operating table.

A blurred, mixed-up mess like a pile of excrement appeared in view.

This kind of fingerprint can't be extracted using the usual powder or magnetic powder methods.

The blurred fingerprint had overlapping and twisted patterns, severely deformed due to external forces.

Conventional extraction methods could only produce a shadowy mass, making post-analysis impossible.

Lu Chuan's method was much simpler: direct photo collection followed by image processing to perform layered extraction of the fingerprint, increasing the probability of successful identification.

Wang Hao took the fluorescent light and began cooperating with Lu Chuan.

Assisting was something Wang Hao only did when he first started working.

However, Lu Chuan's meticulous methods were remarkable; he spent a full two hours on just one operating table.

Of course, the results were gratifying.

Three smudged piles of fingerprints were collected.

In addition, some dried blood samples were collected from the wheel gaps of the operating table.

The next tasks became simpler, with Lu Chuan on the floor scraping the tile gaps one by one.

Wang Hao found a small stool, squatted beside Lu Chuan, watching him use tweezers to pick up clumps of dirty, unidentified material from the tile gaps.

Crime scene work is tedious but also fascinating.

An outwardly "clean" basement hid traces of crime and leftover evidence.

The Binhai Criminal Investigation Team's pre-trial of Chen Gang was still ongoing, while Lu Chuan and Wang Hao's work finally reached its end.

At 4:32 in the morning.

Stretching his back, which was slightly stiff, Lu Chuan grimaced.

Yet seeing a box full of evidence, a satisfied smile spread across Lu Chuan's face.

The dirty materials scraped from the floor filled seventy-two evidence bags.

There was also hair in the sewers, and some skin flakes were extracted from where the sink and basin connected.

Besides that, there were thirteen fingerprints.

"Brother Wang, I'm not very good at evidence testing and analysis; please focus on the DNA testing while I work on fingerprint identification."

Wang Hao nodded somewhat blankly, having worked in crime scene investigation for over ten years. Honestly, he seldom saw such meticulous operations as Lu Chuan's.

Scraping tile gaps, cleaning toilets, rubbing sinks—Wang Hao could do those too.

What made Wang Hao look differently at Lu Chuan were the methods Lu Chuan employed for fingerprint collection.

Many were methods he had neither seen nor heard of.

But the effect was evident; thirteen fingerprints were the strongest evidence.

"Alright, I'll handle the DNA extraction. It's just these fingerprints..."

Thirteen fingerprints were quite a number, but the quality was indescribable.

If one normal fingerprint sample equates to a five foot seven, one hundred ten-pound, curvaceous long-haired beauty,

then the fingerprints Lu Chuan collected... would compare to Yang Sen's niece.

Five feet tall, weighing two hundred pounds, with buckteeth and a bald, pockmarked face.

Really hard to swallow.

"No worries, I've got a way."

Lu Chuan was confident, advanced fingerprint identification analysis, undaunted by anything!
