Official excuse: I've put you on patrol in Handong, and the whole province is in a panic.

Su Zhe turned to look at the operator's technical head.

"Can the call history of this SIM card be retrieved?"

A troubled expression appeared on the face of the technical lead.

"Team Leader Su, the technical standards of analog cards and digital cards are completely different. Digital cards transmit voice messages in an encoded format, which is stored in the system. Analog cards transmit analog signals directly, and the system does not retain call content. Only call records can be found."

"What's in the call log?"

"This SIM card initiated a call at some point, lasting two minutes and fourteen seconds. But the other end's number..."

The technician typed a few keys, and a line of data popped up on the screen.

The "Remote Number" field is blank.

"The signaling format of the analog card is too old, and the record of the other end number is often incomplete, or sometimes it is completely blank. This card is one of them."

"Where is the account holder's information?"

"No real-name registration. The purchase channels for these old cards that circulated in the past are untraceable."

A colleague in the next group couldn't help but mutter under his breath, "What's the difference between this and not checking at all..."

Su Zhe ignored him.

He then had technicians check the call records of all the mobile phone numbers under Ding Yizhen's name that night.

The result was equally clean—there were no abnormal incoming or outgoing calls recorded.

zero.

In other words, Ding Yizhen also used an anonymous card to receive that notification call.

Throw it away after you've hit it, leaving no trace.

Su Zhe stood in front of the screen in the operator's data center, looked at the cold, blank "blank" text, and smiled.

I have to admit, this work is truly beautiful.

The call is between two SIM cards, with both ends remaining anonymous, and the conversation content in between is not recorded.

Even if you were to flip the databases of the three major telecom operators upside down, you would only be able to find "at a certain time and minute, a call was made from a base station near the provincial party committee building"—that's all.

Who made the call, who was it called to, and what was said?

I know nothing about it.

profession.

Qi Tongwei, after all, was a former director of the Public Security Bureau, so doing this kind of thing was a good fit for his skills.

However, Su Zhe did not intend to fight to the death on this line.

He never came here with the intention of finding out the real culprit.

The purpose of this investigation is to thoroughly investigate the process of "I checked but couldn't find the information," thus silencing everyone.

The procedures were followed, and the result is an objective reality.

Nobody could pinpoint what was wrong with it.

Su Zhechong nodded to the operator's technicians.

"Thank you all. Please export the relevant data and cooperate with us to make a written record."

"Okay, okay, boss, we'll definitely cooperate!"

......

Two o'clock in the afternoon.

Su Zhe returned to the inspection team's residence and knocked on Xu Ming's office door.

Xu Ming took off his reading glasses and placed them on the table.

"How is it?"

Su Zhe went through the entire investigation process from beginning to end.

The process of eliminating five people's cell phone records, three phone cards, two digital cards, the technical blind spots of analog cards, and the communication gaps on Ding Yizhen's side.

Each step was explained clearly and logically.

Xu Ming's face grew increasingly grim after hearing this.

"You mean, all possible avenues for investigation have been blocked?"

"To be precise, it wasn't that it was completely blocked; it was that no traceable clues were left from the very beginning. Communicating with another SIM card using another SIM card is inherently almost impossible to track. Anyone who could come up with this trick must be extremely proficient in communication technology and counter-surveillance techniques."

Xu Ming remained silent for a long time.

"In other words," Xu Ming suddenly said, "this person who leaked the information is no ordinary person."

Su Zhe did not respond to that sentence.

Xu Ming walked to the window with his hands behind his back, looked at the blue sky and white clouds of Jingzhou in summer, and suddenly blurted out a sentence.

"Do you think it could be Qi Tongwei?"

Xu Ming added, his voice low but each word clear, "There were only five people at the meeting that day, and after all the back and forth... Ji Changming is a nice guy, he wouldn't take that risk; Chen Hai has no vested interests with Ding Yizhen, so his motive is insufficient; Li Dakang... he has a motive, Ding Yizhen is his man, but I don't think Li Dakang has such professional counter-surveillance awareness and ability!"

"The remaining suspects are Qi Tongwei and Gao Yuliang. Qi Tongwei is the Director of the Public Security Bureau, so this kind of thing is practically his specialty. Although Gao Yuliang is the Secretary of the Political and Legal Affairs Commission, he also has the ability and awareness, but his official reputation is very good, and his motives are questionable..."

Su Zhe: ......

sometimes.

I can't accept it.

People who can reach the provincial or ministerial level are indeed extraordinary.

The 68-year-old man, without leaving home or running errands, simply sat on the sofa drinking herbal tea, and through logical deduction, narrowed down the suspects to the correct answer.

Thinking about this...

Su Zhe was taken aback.

So that's how it is...

There's more than just Xu Ming at the ministerial level.

What about Sha Ruijin?

What about Gao Yuliang?

What about Li Dakang?

They were all from Handong, and they had far more information and knowledge than Xu Ming!

Moreover, these people are all provincial and ministerial level officials!

Did they really have no idea about Ding Yizhen's escape and leak of secrets all along?

Why was Qi Tongwei only brought to justice at the very end?

Su Zhe couldn't help but become wary.

The people of Handong, the affairs of Handong...

None of them are simple!

I must be extremely vigilant and cautious!

Su Zhe looked at Xu Ming and said softly, "Team leader... what do you mean?"

Xu Ming shook his head.

"I don't mean anything by it, my speculation is meaningless! Qi Tongwei is the director of the Provincial Public Security Bureau. Although he's only a department-level official, in such a crucial position, we can't arbitrarily investigate him, much less easily resort to investigative methods. After all, his counter-investigation capabilities and awareness are not something ordinary people possess. For now, we can only presume innocence and continue to observe. However, if any clues emerge later, we should still keep a close eye on Qi Tongwei. I believe he's not as simple as he seems!"

Su Zhe nodded.

"Okay, team leader."

Then.

Su Zhe looked at Xu Ming and smiled, "Team leader, we can't find the person who leaked the information yet, but I don't think we can just let this matter go."

Xu Ming looked at Su Zhe, signaling him to continue.

Su Zhe said, "Not being able to find the leaker doesn't mean there's no one responsible. The entire process of handling Ding Yizhen's escape was riddled with flaws. If there are flaws, someone should be held accountable."

Xu Ming thought for a moment.

"You mean the specific case-handling procedures?"

Su Zhe nodded.

"Yes... many aspects are not compliant..."

Xu Ming waved his hand.

"I won't listen to the details. This matter will be discussed at the five-person group meeting of the Handong Provincial Committee tomorrow, and we will all attend. Just share your thoughts at the meeting!"

Upon hearing this, Su Zhe was taken aback.

"Sir, should I report to you first?"

Xu Ming laughed and said, "You're a talent handpicked by Elder Sun, and also the leader of the special task force. We're not entirely subordinate to each other! What's your responsibility to lead should be your responsibility! Young people should dare to take the lead at crucial moments! Perfect, I'll learn from you then! In short, I fully support your judgment and decisions! Just go for it!"

Hearing Xu Ming's words.

Su Zhe smiled.

"Yes, sir!"

He knew what was going on.

It's likely that before Xu Ming left, Old Sun gave him some advice, telling him to mentor him...

Old Xu simply didn't want to know anything about these kinds of opportunities to get ahead.

We can never repay Old Sun's kindness!
