Ding!

The long-unheard, familiar buzzing sound made Yang Sen and Old Bai, who had just entered the room, pause slightly.

Seeing Lu Chuan in front of the computer, Yang Sen asked in surprise, "Lu, are you comparing fingerprints?"

The fingerprint matching system only makes this special buzzing sound when a complete match is found and successful.

Old Bai casually took a cigarette from the pack of Zhonghua on the table, handed one to Yang Sen, lit one for himself, and walked over to hand one to Lu Chuan: "Didn't you and Old Liu go out for visits this morning?"

The four of them went out together, it didn't seem right.

Taking the cigarette, Lu Chuan held it with both hands, put it in his mouth, and leaned towards Old Bai's lighter: "We did, came back early."

"Since there's nothing going on, I handled the fingerprint matches accumulated this week."

This week?

Yang Sen and Old Bai exchanged a glance, knowing full well about this week's fingerprint matches.

A total of twelve sets, which should have been matched this week.

But the matter of Song Kun's murder delayed it.

Initially, they planned to work overtime over the weekend to get it done.

Unexpectedly, Lu Chuan acted first.

Actually, the usual workload is much larger than this week; typically, it involves fifty sets of fingerprints a week.

The lesser amount this week was also due to the attention taken away by the Song Kun case.

Many cases were temporarily shelved by the police stations and the Criminal Investigation Teams across districts and counties.

"So how did it go? How many sets were successfully matched?"

Yang Sen initially wanted to ask if any fingerprints were successfully matched.

Because that's generally how Crime Scene Investigation work goes, successful matches are rare, and most have issues.

But remembering the buzzing sound they heard upon entering the room, they definitely had at least one successful match.

"Luck was alright, the fingerprints sent over this time were pretty clear; out of twelve sets, nine were successfully matched."

"Nine sets?"

Yang Sen exclaimed in surprise, and Old Bai stopped smoking, looking at Lu Chuan in shock.

"Yes, nine sets is slightly fewer, but the remaining three sets of fingerprints probably don't have target data in the database."

Lu Chuan seemed to misunderstand, explaining why it was nine sets instead of all successful: "I've already put them into the database, so once we collect the fingerprints later, we should be able to match them."

Ahem.

Yang Sen coughed twice: "That's not what I meant, for nine sets… the success rate is very high."

Old Bai nodded heavily, agreeing with Yang Sen: "Very good, in the past, matching ten out of fifty sets in a week was considered good results."

The success rate of fingerprint matching isn't as high as imagined.

Yang Sen and Old Bai aren't slacking off all day; their technical abilities are average.

Under normal working hours, they can process at most seventy or eighty sets of fingerprints a week.

When encountering tricky cases, forty or fifty sets is a full workload.

Successfully matching ten sets is a normal achievement.

Achieving twenty would be an impressive result.

This applies to the Haizhou Criminal Investigation Team and similarly to others.

The teams in Tianzhou and the provincial capital are slightly stronger, but not outrageously so.

Lu Chuan being able to match nine out of twelve sets signifies he is at an expert level.

"Did you two come back too?"

Liu Guodong entered right after them, raising the report in his hand: "How's your investigation going, any findings?"

Seeing Liu Guodong enter, Yang Sen turned around, taking another cigarette from the pack to hand to Liu Guodong: "No suspicions, the two people we checked are Gao Sheng's colleagues, they've been on his electric bike."

Old Bai also walked over, pointing to Lu Chuan in front of the computer: "Lu just finished matching all twelve sets of fingerprints this week, with nine successful."

Hmm?

Liu Guodong paused slightly when they returned from the Qingsong Medical Examination Center, it was noon.

Looking at the time, only three or four hours have passed.

Did they finish a week's work in just one afternoon?

And nine sets were successful?

Lu Chuan stood up, looking at the file folder in Liu Guodong's hand: "Master, did the economic investigation team find anything?"

Putting aside his surprise, fingerprints can wait, the focus is on the case, Liu Guodong's expression changed, handing the folder to Lu Chuan.

"This Wang Manli... does seem to have some suspicious points."

Opening the folder, there was a stack of bank transaction statements.

The economic investigation team is indeed professional, containing all statements from Wang Manli's four bank accounts.

"This Wang Manli's income… is unusually high."

Pulling out one of the transaction statements, Liu Guodong pointed to an income record at the bottom: "Lu, you said you saw Wang Manli at the Haizhou International Hotel last night, check the time of this transaction."

Lu Chuan took the statement, slightly surprised.

Transaction time: 20:02, transaction amount: 100,000 yuan.

Holy crap.

Lu Chuan was a bit shocked.

What on earth, costing ten thousand per time?

Liu Guodong apparently noticed Lu Chuan's shock: "And there's more, this is Wang Manli's annual income statement."

"She worked at Qingsong Medical Examination Center for three years, earning roughly seventy thousand a year in salary and bonuses."

"However, her other income amounts to about a million per year."

A million?

Hearing this income, Yang Sen and Old Bai came over: "Is this woman a fairy?"

"Indeed, earning a million a year… a bit exaggerated, right?"

Lu Chuan frowned, while Wang Manli was indeed quite attractive, but ten grand per occasion, a million per year…

"Master, are all these transactions from different people?"

Liu Guodong nodded: "Mostly from different companies, the largest transaction being thirty thousand and the smallest five thousand."

Company transactions?

And the largest amount being thirty thousand?

In that case, it's unlikely Wang Manli is involved in prostitution.

Yang Sen and Old Bai clearly understood Liu Guodong's point: "Is this woman possibly involved in illegal activities?"

Liu Guodong nodded: "It's not certain yet, but her income source definitely seems problematic at present."

"The economic investigation team is already looking into the situation of all accounts that transferred money to Wang Manli, results should be available tomorrow morning."

"Should we report to Captain Qin?"

Since Wang Manli is suspicious, could it be related to Gao Sheng's disappearance?

Liu Guodong shook his head, denying Lu Chuan's suggestion: "Based on current leads, there's no clear connection between Gao Sheng's disappearance and Wang Manli."

This point is sufficiently supported by today's investigation.

"Perhaps Wang Manli is only involved in some economic issues, so we should continue investigating."

"It's been a week since Song Kun's murder, let's refrain from reporting this minor issue for now."
