Chapter 727: How Many More Days Can You Hold Out?

If there are hidden cameras in the room, even when invisible to the naked eye, turning on the phone’s video will reveal flashing red dots.

Not all cameras can be detected this way, but the vast majority cannot escape this method.

Yu Dazhang did not want to make a mistake at this stage.

He inspected the room not because he suspected the hotel had tampered with it—actually, many hidden cameras were placed by guests themselves.

Some people even specialized in this, deliberately filming indecent content to sell to websites for profit.

Two officers were stationed inside the room, and Yu Dazhang and Hua Dui left.

“I booked two additional rooms right next door.”

Hua Dui pulled out two key cards:

“One double room and one triple room—we can use them as our rest area.”

He really knows how to get things done… Yu Dazhang nodded in satisfaction.

Zhang Jiangke could sleep peacefully, but the officers guarding him could not relax for a moment—they had to take turns on duty.

To prevent the guards from becoming overly fatigued, at least three shifts were required.

After a brief discussion, they assigned one shift of officers to guard during the day.

After ten p.m., however, due to the human circadian rhythm causing drowsiness, shift changes needed to be more frequent.

Shifts rotated every two hours to ensure the guards remained fully alert.

Over the next several days, a nationwide operation was launched to apprehend human traffickers.

Often, arresting one person would lead to a whole chain of arrests.

Especially this time—Yu Dazhang’s team had captured seasoned traffickers, and their networks alone kept national criminal investigators busy.

Even Songhai wasn’t idle; Lu Zhongxin even called Yu Dazhang to ask when he’d return to the unit.

Clearly, the First Detachment had also joined the operation.

Yu Dazhang naturally could not return—he still had more important tasks to accomplish.

For these past few days, they had been on rotating shifts, and Yu Dazhang himself had remained steadfast in the hotel, never leaving.

But he wasn’t just waiting idly.

During this time, through continuous interrogation of Zhang Jiangke, he obtained many critical pieces of information.

Almost every day, seasoned traffickers came under police surveillance.

Know that Zhang Jiangke was no ordinary trafficker.

The lowest rung he dealt with were second-tier traffickers like Zhang Qian.

The low-level thugs who personally carried out kidnappings weren’t even worth his attention.

The fifth day of their stay at the hotel.

Members of the special task force were gradually growing restless.

Even Xu Dui and Hua Dui were no exception—both had begun sighing frequently.

“If we keep arresting like this, Gu Dingwen won’t dare show his face.”

In the adjacent room, Xu Dui complained to Yu Dazhang:

“Waiting like this isn’t viable—we might end up with the suspect already fleeing abroad.”

His concern wasn’t unfounded; after all, Gu Dingwen had met Zhang Jiangke in Mianbei, meaning he had connections there.

Escaping to Mianbei wasn’t difficult.

With the right contacts and enough money, specialists would help him cross the border illegally.

One major reason why telecom fraud in Mianbei is so rampant is that illegal crossing is relatively easy.

“Do you have another plan?” Yu Dazhang asked in return.
