"Isn't there a need to rush? This place is very close to your police station. I do have a question to ask."

Xia Che stretched out his palm, pressed it a few times, and smiled, signaling Xiao Yihan to calm down.

"Okay... what's the problem?"

Xiao Yihan sat back down, raising her eyebrows slightly.

“This is something I just realized… Your police station’s target is basically confirmed to be Old Dog, right? But his usual method is disguise. I also know a few masters of disguise who can disguise themselves without leaving any flaws, but they have a fatal weakness… fingerprints.”

Xia Che placed his hands together on the table, looked at Xiao Yihan, and asked, "Everyone's fingerprints are different, which is the most direct and effective way to prove their identity. Did your target not leave any fingerprints at all from beginning to end?"

“No, there really isn’t. He’s just that difficult to deal with. He’s committed so many crimes, but we’ve never found any fingerprints or hair at the scene. We’ve considered using those things to identify him, but we’ve never left such a clue. How can we investigate?”

Xiao Yihan gave a wry smile; mosquitoes are just so troublesome.

Otherwise, so much time would have passed and law enforcement wouldn't have been able to do anything about him.

Although law enforcement officers hate mosquitoes to the core, they can't help but sigh...

This guy is definitely a born criminal.

"Strange... It's possible not to leave any hair, like a criminal might shave their head or trim their hair before committing a crime, but not leaving any fingerprints... How is that possible?"

Xia Che raised his palm and looked at his fingerprints.

This thing is everyone's identifier.

If you pick up anything, you'll definitely leave a mark.

Don't be fooled by those undercover agents in TV dramas who are so experienced they can wipe away their fingerprints beforehand... In reality, that's all nonsense.

No one could be that careful, nor could anyone accurately erase any fingerprints they leave behind.

A dusty table, fingerprints are easily wiped away by anyone.

But what if this table doesn't allow you to wipe off the dust?

For example, on a dust-free table, how do you determine which part you left your fingerprints on?

Do we have to wipe the entire table clean?

Mosquito is a con artist; he must deceive his target as quickly as possible, get the money, and leave swiftly.

Give him time to carefully wipe away every fingerprint...

That's impossible.

There simply isn't enough time.

Not to mention, in reality, there are many places where you are unaware that you have left fingerprints.

It's not as simple as wiping a table, where you can just wipe away fingerprints.

He committed so many crimes, yet he never left a single fingerprint...

Xia Che rubbed his temples, gaining a new understanding of how troublesome the old dog was.

"However... according to you, this target should be considered ruthless, a ruthless criminal, and he has no shortage of cases that swindle people out of their fortunes. Such a villain... how come he has never killed anyone? That's a bit strange. Did you not tell me, or... is it that he really has never killed anyone?"

Xia Che frowned; this was indeed the part that puzzled him the most.

Logically speaking, the crime committed by the other party is enough to warrant a lifetime in prison.

According to the criminal psychology that Xia Che had read, a criminal who can no longer see the future is very likely to kill his victim during the crime, so why didn't he do so?

"What, you're really looking forward to him killing someone?"

Xiao Yihan rolled her eyes at him, annoyed: "Can't you hope for something better?"

"Just out of curiosity, and as I just mentioned, they were just some minor questions."

Xia Che smiled sheepishly.

“He certainly doesn’t have any murder on his hands… or maybe he did, but it went undetected? That’s almost impossible, because we have records of all the cases he’s committed in the police station. He only cheats people out of money and doesn’t kill them. In a way, he does have some principles.”

"Never mind... never mind what I said."

Xiao Yihan rubbed her face and sighed helplessly.

All right……

It's incredibly foolish to say that a con artist who has swindled countless families out of their fortunes has any moral bottom line.

Xia Che smiled but didn't say anything, clearly realizing the problem earlier than Xiao Yihan.

"Alright, I have no more questions."

Xia Che had asked what he needed to ask, and stood up to say goodbye to Xiao Yihan.

"Keep in constant contact by phone. The other party is a common enemy of both of us. We must keep our intelligence flowing at all times. To be honest... your plan is too audacious. After all, the opponent is a well-known fraudster. Well... even if it's infamy, it's still a name."

Xiao Yihan reached out her hand, and Xia Che took it at the right moment. Their palms met, and Xiao Yihan felt the warmth from Xia Che's hand. Her delicate face unconsciously flushed slightly.

But now is not the time for romance. Although Xiao Yihan also wanted to stay by Xia Che's side because it made her feel relaxed, now was not the right time.

"Even if you say that... at least tell me Old Dog's code name in your police station, right? Although I know I'm just a civilian, this kind of behavior of keeping information from me when you clearly have it is a bit too much."

Xia Che raised an eyebrow, a hint of a smile in his eyes.

"mosquito."

Xiao Yihan hesitated for a moment, but still told Xia Che.

He's right. Now that they're on the same side, they really shouldn't keep it from Xia Che.

It's just a code name; it doesn't violate the police department's confidentiality agreement.

"You actually said that? I was just teasing you."

Xia Che said in surprise, his expression still that same cheeky look that Xiao Yihan was familiar with.

"Pah, you're kidding me..."

Xiao Yihan rolled her eyes in annoyance, then reluctantly pulled her hand out of Xia Che's palm. The rest time was up, and she couldn't delay any longer.

After all, it's the joint work of the police officers, and Xiao Yihan can't be given special treatment.

"Go ahead, I'm going back too."

Xia Che smiled and waved. After a long day, he was so tired that he felt he could fall asleep as soon as he lay down on the bed.

The plan is half complete; now it remains to be seen how long the old dog can endure it.

The public opinion will officially start to ferment tomorrow, and Old Dog will probably realize that something is wrong in the next day or two.

"The most crucial moment is yet to come..."

Xia Che let out a long sigh, watching Xiao Yihan's slender figure disappear into the distance. Then he paid the bill himself, put his hands in his pockets, and walked out of the coffee shop.

...

Night fell, and the moon and stars were few.

The lock on Xia Che's room has been changed. Although Xia Che insisted on changing it to a combination lock, the women, who all had ulterior motives, naturally wouldn't allow them to do so.
