In this USB drive, besides some case details, there's also some rather sensitive content.

For instance, someone once privately approached Lin Bin, hoping he could help handle some matters, but Lin Bin refused.

Among these people, there are officials as well as businessmen.

Song Guanchao just glanced at it briefly and pulled out the USB drive.

The content inside, if you call it sensitive, it is indeed somewhat sensitive.

But it's not sensitive enough to determine the life or death of certain people.

Song Guanchao couldn't help but feel puzzled; since this is the case, what exactly does the person contacting Li Rong and sponsoring her want to find?

He shook his head, lazily deciding not to think about it.

This matter has nothing to do with him; he only cares about the undercover agent's file.

Although he hasn't found the file now, at least he knows the undercover agent does exist.

He's mostly convinced of Tan Xiang's identity.

And what she said about there being undercover agents planted by criminal organizations within the police, Song Guanchao believes that too.

However, he cannot confirm if the undercover agent is among these deputy directors.

If there really is an undercover agent hidden among the deputy directors, then Lei Group temporarily changing the transaction time is laughably foolish.

An undercover agent who is deputy director could never be an idiot.

So Song Guanchao is more inclined to think that Lei Group changing the transaction time is purely coincidental.

But Tan Xiang clearly doesn't think so.

She believes the other party's purpose is to expose the traitor.

But the current situation doesn't provide enough proof for this conclusion.

Now, they can only wait for the next transaction.

Just as Song Guanchao was thinking this, Tan Xiang's call suddenly came in.

"Chairman Tan, what's up?"

"The undercover agent is among these deputy directors!"

Tan Xiang started with this statement, immediately snapping Song Guanchao to attention.

"How did you determine that?"

"I'll send you the evidence shortly."

There is even evidence, Song Guanchao suppressed his surprise: "Alright, send it over."

After hanging up, Tan Xiang sent over a video.

The video shows a private room, besides the person secretly filming, there's only one man inside.

The person filming asks the man when Uncle Nan changed the transaction date to.

The man says, it was changed to Wednesday afternoon.

The video is very short, just this conversation.

But it's enough.

This is enough to show that Lei Group's temporary change of the transaction date was indeed to flush out the traitor.

There is indeed an undercover agent planted inside the police station!

Moreover, the undercover agent is hidden among these deputy directors!

Tan Xiang's phone call came again.

She didn't speak, seeming to wait for Song Guanchao to say something.

"Where is your informant now?"

"Ran away."

"Looks like this matter needs to be brought to light."

Song Guanchao chuckled.

With the traitor running, the situation can't be contained.

The undercover agent will soon know that the test against him has achieved its purpose.

"I'll try to quickly find out the identity of the undercover agent."

Tan Xiang agreed with a simple "hmm," and before hanging up, reminded him: "Be careful yourself."

"Got it."

After hanging up, Song Guanchao reopened his computer and quickly checked the information on all deputy directors in the Jiangzhou Public Security Bureau.

The city bureau has a total of five deputy directors, one director, one political commissar.

The political commissar is the same level as the director, but doesn't have as much actual power.

However, Wen Ru is a bit special, because before Liang Jianfeng took office, the position of city bureau director had been vacant for several months.

So strictly speaking, Wen Ru has more actual power than Liang Jianfeng.

Song Guanchao looked at the names of the five deputy directors, carefully examining their positions, seemingly trying to analyze who is more likely to be the undercover agent based on their positions.

As for Wen Ru, she was subconsciously ignored by him.

In his subconscious, Wen Ru couldn't be an undercover agent.

Ultimately, his eyes fell on one deputy director named Chen Peng.

This Director Chen is in charge of narcotics work.

His responsible work makes Song Guanchao naturally focus his suspicion on him.

However, to confirm, he'll still need to find a way to investigate.

Checking the time, he called Liang Jiajia.

Liang Jiajia hadn't been working overtime today, she was home alone.

The two arranged to meet at the mall, shopping, dining, and the sky grew dark as they drove to the hotel.

Passing an intersection, he looked around, checking the rearview mirror.

Two kilometers from the hotel, passing another intersection, he again observed the surroundings and behind.

"How's your investigation going?"

As Liang Jiajia spoke, Song Guanchao immediately said, "Don't speak yet."

She curiously looked over, seeing Song Guanchao with a solemn expression, occasionally glancing at the rearview mirror.

After a few minutes, she noticed Song Guanchao was taking a wrong turn.

Just about to remind him, she closed her mouth again.

Because Song Guanchao's face grew even more serious.

Seeing him glance at the rearview mirror from time to time, Liang Jiajia couldn't help but speculate, was someone following him?

Song Guanchao initially only noticed a car trailing him, at first he didn't pay it any mind.

After all, traffic was heavy at this time, maybe they were just on the same route.

But eventually he realized, if he drove slowly, the car behind also slowed down.

If he sped up, they followed suit, always staying within range.

He changed directions several times, they followed each time.

He was almost certain he was being tailed.

Was it that mysterious person contacting Li Rong?

Or the undercover agent hidden within the police?

As he was thinking, the car behind suddenly turned away and left.

Song Guanchao was a bit surprised, did they notice I discovered them?

He hesitated whether to follow them, but they'd already merged into traffic and disappeared.

Never mind, not worth chasing.

After all, Liang Jiajia was still in the car.

After more than ten minutes, the car stopped at the hotel.

After checking in, and entering the room, Liang Jiajia finally asks, "Someone following us just now?"

Song Guanchao nodded, sat down, and shared the investigation on Li Rong with her.

After finishing, he asked, "Do you think it was the person in contact with Li Rong following me, or the police undercover agent?"

Liang Jiajia considered, "I think it might be the person in contact with Li Rong."

Song Guanchao agreed.

But he couldn't help considering, if it were Zeng Li, what would she think?

That girl's got a sharp mind, and always brings him a different perspective in analyzing these matters.

"You're really not planning to tell my dad about the undercover situation?"

"Not yet."

"You're worried he won't let you keep investigating?"

"No," said Song Guanchao, "I'm worried he won't let me use illegal methods to investigate."

Liang Jiajia rolled her eyes, "My dad's not that rigid, I suggest you better tell him, after all, with such a big thing, he might be able to help you out."

Song Guanchao looked at her, "You're sure he can tolerate my investigative methods?"

"Of course, he's my dad, I know him better than you."

"Alright then."

Ultimately, Song Guanchao decided to tell Liang Jianfeng.

Just like she said, now that it's confirmed an undercover agent exists, it can't be kept hidden anymore.

With help from the police bureau chief, it'll definitely be easier than going at it alone.

"Come on, let's go shower!"

Song Guanchao chuckled, reaching his hand towards the hem of her skirt.
