At the security office of the office building.
After Xu Mo and his team revealed their police identity and communicated with the security guards, they began reviewing the surveillance footage with the guards' assistance.
First, they checked the elevator surveillance and found that the man in the suit had gone to the 22nd floor.
They then examined the hallway cameras on the 22nd floor, where they saw the suited man enter an office with a "Jufeng Investment" sign at the entrance.
"Jufeng Investment... this must be their headquarters, right?" one officer looked at his three companions.
"I'd say that's almost certain. This place is definitely a front - looks like an investment company but it's actually for money laundering! Should we go up and arrest them now?"
"Arrest them? There's only four of us, and we don't know how many of them there are. If they outnumber us, rushing in would be like throwing dumplings to a dog - useless and we'd alert them. It'd be much harder to catch them later."
"You're right. I'll call for backup now, and we'll keep watch here," the officer said, taking out his phone to call Li Yunfei and the others.
Xu Mo didn't participate in the officers' discussion.
He turned to the security guard: "Uncle, may I use this computer?"
"Of course, go ahead, feel free!" the guard nodded without hesitation.
He was happy to help the police, especially for something as simple as using a computer.
"Thanks."
After expressing his gratitude, Xu Mo began working on the computer, planning to do some quick hacking to investigate Jufeng Investment.
The three local officers watched Xu Mo at work.
Though they weren't sure what he was doing, seeing his fluid movements and hearing his rapid keystrokes, they immediately gained respect for him.
They exchanged glances, remembering Xu Mo's other identity - a hacker!
As police officers, they were familiar with common money laundering methods.
Money could be laundered through movie production, small livestreaming platform donations, online gambling sites, or high-priced art auctions.
More complex methods involved breaking large sums of dirty money into smaller amounts and distributing them across numerous overseas accounts, where a single sum might be transferred hundreds of times or more, making its origin difficult to trace before being transferred back to specific cards.
The most sophisticated and hard-to-detect money laundering techniques were rare.
Most criminals involved in money laundering didn't possess exceptional skills - if they did, they probably wouldn't have chosen a life of crime. Therefore, truly ingenious money laundering schemes were uncommon, with most methods being relatively simple and leaving traceable evidence.
After a few minutes, Xu Mo successfully hacked into their office computers.
They were actively laundering money by splitting it into smaller amounts and routing it through overseas accounts before transferring it back.
Since this method required substantial manpower for splitting amounts and making transfers, they had to recruit many employees to handle these tasks. Xu Mo, having hacked in, could see all their operations clearly.
"Confirmed - even if this isn't their main headquarters, Jufeng Investment is definitely one of their primary money laundering operations. It's a front - the investment company is just a cover. The employees upstairs are laundering money by breaking down illegal funds into smaller amounts and routing them through overseas accounts before bringing them back," Xu Mo concluded after his investigation.
"Oh, and there are about 70-80 employees up there. I suggest calling for more backup before making any moves."
"70-80 people? We definitely need more backup..." the officer muttered before calling headquarters to report the situation.
Given the large number of people involved, they needed enough officers to ensure a successful operation without complications. This would be a joint operation between different district police forces to arrest the members of the money laundering organization.
...
Half an hour later.
Police cars from all directions filled the area around the office building, and officers had completely surrounded the building.
Curious passersby were shocked.
"What the hell is going on? Why are there so many police?"
"Is there a murderer in the building?"
"What? There's a serial killer case in there?"
"What's happening up ahead? Why are so many people gathering?"
"You don't know? There are terrorists in there!"
"Damn, there's a terrorist with bombs in there! He's going to take down a whole floor of people!"
"What? A terrorist is going to blow up the office building?"
"..."
As more people gathered to watch, the rumors grew increasingly outlandish... all sorts of theories circulated.
The officers who arrived first organized their deployment.
Some officers remained downstairs to prevent any criminals from escaping in the chaos, while others entered the building to carry out the arrests.
22nd floor.
Jufeng Investment.
Bang! The office door was kicked open.
A group of officers rushed in: "Nobody move! Hands up and squat down with your hands behind your heads!"
Seeing the uniformed officers enter, the employees immediately realized something was wrong, and a chorus of expletives erupted throughout the office.
The office instantly descended into chaos.
Even with officers guarding the door, some people still tried to run.
Of course, they couldn't escape - the police had come prepared with the intention of catching everyone at once.
With the coordinated efforts of numerous officers, the chaos was quickly contained. Most of the money laundering gang members were arrested, while the rest obediently squatted in the corners with their hands behind their heads.
"Officer, you've got the wrong person - I'm just a repairman! I'm here to fix the air conditioning!"
"I'm a repairman too, I'm here to fix the plumbing!"
"Me too, I'm here to fix the computers!"
"..."
Several tried to cleverly claim their innocence, but the officers had heard such excuses countless times and simply responded: "You can explain at the police station."
Through the coordinated efforts of the many officers, all 70-80 employees involved in the money laundering operation were apprehended and escorted downstairs in groups.
