551: Chapter 504: A Good Start_2 551: Chapter 504: A Good Start_2 Jiang Yuan then took out a new set of fingerprint powder and a brush.

There are many ways to visualize fingerprints, including but not limited to various fingerprint powders, cyanoacrylate (superglue), and ninhydrin, among others.

In theory, even gold could be used to cast the fingerprints, but there was no need for Jiang Yuan to go to such lengths for fingerprints that were not confirmed to be important.

Most of the fingerprints in the room were actually duplicates.

The fingerprint technicians before had collected them, and most of those stored in the fingerprint database could be matched.

Those that couldn’t be matched were probably not in the database, and there wasn’t much point for Jiang Yuan to spend time on them.

Therefore, Jiang Yuan didn’t search in obvious places, like the surface of the desks or safes.

Fingerprints there had definitely been wiped clean time and again.

Of course, this was also because the main office area received more attention, and there were more forensic investigators there.

They didn’t need to leave the sixth floor.

Once they stepped out of the main office area, the thoroughness of the investigations significantly decreased.

Nonetheless, Jiang Yuan still checked the main office area thoroughly today.

In addition to fingerprints, he also paid attention to footprints and other traces, including those left by bullets.

By the time evening fell, Jiang Yuan finally found most of an unfamiliar fingerprint next to a water dispenser.

He easily marked 13 characteristic points and, after running it twice in the system, identified a 22-year-old young male.

Jiang Yuan marked it in the system and took a photograph with his phone, sending it to Jin, the deputy commander of the drug enforcement unit.

It was highly likely that the individual was a mid-level manager in Huang Li’s gang, perhaps a distributor or even one of their bodyguards.

Jiang Yuan didn’t need to differentiate.

Securing the building had its advantages; any fingerprint found here was very likely not innocent.

In other words, every fingerprint in this building had to be initially tagged as guilty.

Even the cleaners and the janitorial staff couldn’t possibly be unaware of what happened in the building.

Having done all this, Jiang Yuan then turned around and said, “Let’s head back for dinner, we’ll stay at the police station tonight.”

Mu Zhiyang and Lu Tongda, carrying things and exhausted, agreed immediately.

After instructing the remaining staff to be vigilant about safety, Jiang Yuan returned to a corner of the criminal police office and set up a folding bed for himself, where he nestled in to review the fingerprints and footprints from the back-end system to facilitate the continuation of the investigation the next day.

Mu Zhiyang gave Lu Tongda a folding bed and set up his own next to Jiang Yuan, then sighed and said, “Our combined net worth must be at least a whole apartment building, yet here we are sleeping on these three beds that cost just 99 each.”

“These beds are three for 99?

Got a link?” Lu Tongda’s eyes lit up, thinking that as a bachelor, if he had a folding bed at his office, one in his car, and another in his living room, wouldn’t that elevate his life to a whole new level?

Mu Zhiyang coughed twice and said, “I exaggerated a bit.

It’s buy two get one free, altogether about one hundred seventy-eight.

Get the spirit of it.”

“That’s not bad either, what’s the keyword?” Lu Tongda stretched out and started browsing online shopping sites.

He even placed an order, his splurge momentarily outshining Jiang Yuan.

…

Early in the morning.

Jiang Yuan woke up to the strong scent of sandalwood.

“This scent…

it’s kind of familiar…” After washing his face with mineral water and wiping it with tissue paper, Jiang Yuan stepped out of the office.

The door across the room was open, letting out a hint of fragrance.

Entering the room, Jiang Yuan indeed saw a familiar sight of red chicken eggs, red duck eggs, red goose eggs…

and in the middle, a green emu egg.

“Master,” Jiang Yuan called out.

Wu Jun, with his back to the door, gestured for Jiang Yuan to come closer and said, “Come here and help me take a look at this.”

Jiang Yuan strode over and saw a cleaning robot lying bare on the table in front of Wu Jun.

“What is this?”

“Bought it second-hand online, I want to take it back and give it a try.

Everyone talks about ‘sweeping monks,’ and since we believe in the Three Pure Ones, we should also take on the task of sweeping.”

Jiang Yuan hesitated and asked, “Does using a cleaning robot count as doing the chore?”

“Of course, it counts,” Wu Jun argued, “A big monk sweeps with a broom, mops with a mop; aren’t those just tools?

Now it’s a new era, and the tool has evolved into a cleaning robot.

Using a cleaning robot naturally counts as doing the chore…

and I am not doing nothing, I’ve been fixing this thing all morning.”

“Alright then…

But can we really believe in the Three Pure Ones?”

“We must believe.

It is also promoted by the higher-ups,” Wu Jun counted off on his fingers, “Clearing up police cases daily, settling cases monthly, and eradicating backlogged cases each quarter—Ningtai County is now a model of the ‘Three Clears’ in Shannan Province.”

What could Jiang Yuan say?

He could only peel a red-boiled egg for breakfast.

“Your injury isn’t serious, is it?” Wu Jun handed him a cup of clear tea and asked.

“A slight concussion maybe, bruised a few spots on my leg, and my left arm is slightly pulled.

There are a few minor strains elsewhere, nothing else; at most they’re minor injuries.” Jiang Yuan explained a bit more in detail.

Wu Jun nodded as he listened; if that was indeed the case, then the injuries weren’t serious.

“It’s good that you’ve been obedient and paid your respects when needed,” Wu Jun thought for a moment and added, “Alright, go do what you need to.

I’ll back you up here.”

“Back me up…

on what?” Jiang Yuan was a bit hesitant.

“Are you sticking around to listen?” Wu Jun countered, taking on the air of a master.

“No, no need.” Jiang Yuan hurriedly shook his head.

“As I was saying,” Wu Jun continued, taking out a peach wood sword the length of his palm and placing it softly on the table before closing his eyes slightly, “you’re working in Changyang, and despite your strong capabilities, it’s still not easy.

Just do what you have to, I’ve got your back here.”

Jiang Yuan, not daring to say more, grabbed a few eggs and left.

Back in the office, he distributed the eggs to Mu Zhiyang and Lu Tongda, tidied up a bit, and then headed straight to the crime scene in Shuidong.

Since Huang Li’s office had already been searched last time, Jiang Yuan chose the basement this time.

Upon entering, he saw several broken mechanical parts piled up at the entrance.

The battle in the basement had been quite intense; the equipment of the police and armed police could already smash most items in urban combat.

Jiang Yuan subconsciously picked up a piece of mechanical part—a bent water pipe, one end broken and the other screwed with a small component.

He couldn’t help but wonder if the connection between the component and the water pipe might bear fingerprints or DNA traces.

He immediately unscrewed the threaded structure connecting the two.

Upon shining a light on it, a faint fingerprint indeed appeared.

“Luck’s on our side!”

Mu Zhiyang, who had his fill of red-boiled eggs, immediately exclaimed.

Jiang Yuan’s eyes lit up; there was a high probability that the fingerprint was left by the installer.

In the basement of the building where Huang Li’s gang was based, the only thing requiring an installer would be the drug manufacturing machine.
