Chapter 693: Comparing People Can Really Make One So Angry It Kills

"Do you think Zhang Jiangke is in Qingpu District?"

Captain Hua heard it; Yu Dazhang was simply waiting for this time of night.

It is now nine-thirty in the evening.

This time is also when people are about to rest.

And this sixty-one-year-old old man, Zhang Jiangke, will most likely not stay up late; at this time, he has very likely already rested.

Once people get older, their body's biological clock shifts forward; this is a normal physiological change.

In medicine, it is called circadian rhythm change, or "advanced sleep phase syndrome in the elderly."

Simply put, it means getting sleepy early and waking up early.

Many young people hold a thought: When I get old, I'll sleep in every day, sleep hard, sleep to death.

But when you actually get old, you will discover you wake up earlier than chickens every day and simply cannot fall asleep.

"Not just Qingpu District."

Yu Dazhang answered:

"Analyzing Zhang Jiangke's past patterns of booking hotel rooms, the places he is most likely to stay are Hongkou and Qingpu Districts."

"He has booking records in almost all sixteen districts of the city, except for these two."

He continued explaining:

"Once certain habits are formed, they are hard to break, so I conclude he will definitely stay in a hotel in these two districts this time."

"During the day, you finished screening the small hotels in Hongkou District; next, only Qingpu District remains."

"And this time period is the perfect moment for us to take him down in one stroke."

Yu Dazhang did not believe this old fox, Zhang Jiangke, could withstand his biological clock.

So as long as he is in Qingpu District, we will definitely find him tonight.

And the reason of cracking down on prostitution can also minimize the other party's alertness to the maximum extent.

Do you know why anti-prostitution operations are always conducted at night?

That's right, it is exactly what you think.

Because nighttime is the peak period for prostitution-related activities; this involves human nature.

"I understand."

Captain Hua replied:

"This is a coordinated operation; we will not give Zhang Jiangke time to react."

Secret investigation during the day, sudden raid at night... Captain Hua only now understood Yu Dazhang's intention.

At the same time, he could not help but feel somewhat struck.

That fat man is far away in S Province, yet he can still command the situation here in Songhai in an orderly manner, even calculating every single step.

And I am here, yet I cannot even figure out his intention.

Comparing people can really make one so angry it kills.

At this very moment, S Province.

Xicheng City Public Security Bureau.

As soon as Yu Dazhang put down the phone, Captain Xu walked in holding a document.

"The matter in Jin Ling has been clarified."

Captain Xu placed the document on the desk in front of Yu Dazhang:

"Zhang Jiangke did indeed book two rooms, but only he was registered with a real name."

Yu Dazhang frowned slightly and asked in confusion:

"Then what about the other room? Who did he book it for?"

He wanted to ask Zhang Jiangke's purpose for booking the other room.

But based on previous deductions, he had already confirmed that Zhang Jiangke came to Jin Ling to meet someone, so the other room must have been booked by Zhang Jiangke for another person.

Captain Xu stood beside Yu Dazhang, pointed to the relevant records in the document, and explained:

"He did indeed book the other room for someone else, but that person did not spend the night in the room; they should be considered a visitor coming to see him, so the hotel did not require a real-name registration for them."

After a pause, he added:

"However, the hotel's surveillance camera captured an image of that person; through the surveillance footage we intercepted, we have found that person's identity information."

This was handled reliably... As soon as Yu Dazhang heard that the person's identity information had been found, he immediately picked up the document on the desk.
