Chapter 29: Spontaneous Passion Crime

This wasn’t something Yu Dazhang should have said, but coming from his mouth, everyone felt it was only natural.

At this moment, everyone—including Lu Zhongxin—looked at Yu Dazhang with serious expressions.

“Master, you continue interrogating the suspect; that part remains unchanged.”

Then he glanced at the others and continued:

“I need four more people, two teams of two, to investigate the suspect’s and victim’s social relationships.”

Yu Dazhang didn’t assign them directly because he wasn’t familiar with these team members.

Even in his past life, he’d only nodded to them in passing; most he didn’t even know by name.

After all, they weren’t from the same squad and had never worked together, so their interactions were minimal.

“I’ll go—I drive steady and fast.”

“Count me in—surveillance and tracking are my strengths.”

“I’ve worked in household registration—I can access records more easily.”

“...”

Quickly, four people stepped forward and naturally formed two teams.

Yu Dazhang nodded in satisfaction.

These people were even more eager than he was—perfectly handy to use.

Just before leaving, one team member looked at Yu Dazhang and said:

“Let me be clear—I’m not questioning you, I just want to know: the suspect is already in custody, so why investigate both sides’ social relationships?”

The other three also turned to Yu Dazhang; clearly, this was their shared doubt.

Especially the two assigned to investigate Kong Lingjie—they practically had “confused” written on their faces.

His household register lists only him—he has no relatives or friends in Songhai. What’s left to investigate?

Would you dare ask that if you were in charge?... Yu Dazhang smiled and asked back:

“Can you be certain Kong Lingjie is the one who killed Zhang Yan?”

“This...” The man was speechless. After a pause, he could only speak honestly:

“I can’t be certain.”

When he first joined the special task force, he was certain—but now, he wasn’t.

This case had already pushed this fatty to new heights.

Even the primary crime scene had been dismissed—no one could predict what would happen next.

“Then let’s assume,” Yu Dazhang continued. “Assume tomorrow’s interrogation reveals Kong Lingjie isn’t the killer. What does that mean?”

The team member’s head buzzed from the question.

It means you’re turning this case into an unsolved mystery.

It means we’re all in trouble.

What else could it mean? You’re just asking nonsense.

He dared only think these words inside his head—right now, this fatty was effectively their team leader, and no one dared challenge him openly.

What if he quit? They’d all be left utterly lost.

He’s a newcomer—he doesn’t care, doesn’t bear responsibility—but we can’t afford that.

So he could only shake his head, admitting he had no answer.

Yu Dazhang dropped his smile and spoke with solemn seriousness:

“It means this case is not a spontaneous passion crime.”

As soon as the professional term was spoken, everyone instantly grasped the key point.

If Kong Lingjie isn’t the killer, then he’s taking the blame for someone else.

Here’s the crucial question: spontaneous passion crimes don’t require someone to take the blame.

Does that sound confusing?

Doesn’t matter—first, let’s define what a spontaneous passion crime is.

Simply put: sudden, uncontrollable emotional outburst.

Put simply, it means emotions suddenly surge to an uncontrollable level.

Two strangers brush shoulders on the street.

Two strangers brushing past each other on the street accidentally bump shoulders.

“Can you speak human?”

“F*** you, you...”

“Who the hell are you talking to?!”

Draw knife~

Stab stab stab stab stab~

One man collapses in a pool of blood... Bao Gai Jia Yuan.

If the perpetrator deliberately sought someone to take the blame, wouldn’t that be like covering one’s ears while stealing a bell?

You had no prior connection to the victim—yet you send police a person tied to you.

Are you afraid they won’t find you?

Anyone with half a brain wouldn’t do that.

So, if someone actively finds a substitute, the killer and victim likely share an inseparable bond.

And such a bond easily suggests certain possibilities.

Like: enemy, creditor, lover...

That’s why Yu Dazhang sent them to investigate Zhang Yan’s social relationships.

What kind of mind does he have...? The team was stunned again by Yu Dazhang’s logic.

Please... collect... 6...9...books...!

Anticipating the case’s direction and acting immediately—is this really a newcomer?

“Uh, I have another question,” one of the investigators assigned to Kong Lingjie asked.

“The suspect’s social ties are already clear—is there still need for deeper digging?”

“Of course,” Yu Dazhang nodded firmly. “If he’s taking the blame for someone else, what kind of bond would make him do it? Remember, the sentence could easily be death.”

Exactly—that’s another critical point.

First, eliminate the possibility of money-driven substitution.

His household register lists only him—he has no one to give the money to even if he got it.

Spending it on himself is even less likely.

Imagine this dialogue...

“Ten million. Take the blame for someone.”

“Sure! I’m in. What crime? How many years?”

“Intentional homicide. Executed next April.”

Who in their right mind would take that job?

So if Kong Lingjie isn’t the killer, his connection to the real perpetrator must be extraordinary.

The team member nodded thoughtfully:

“Then where should we look? All visible relationships have already been checked.”

He wasn’t setting a trap—he genuinely had no idea.

Everything that should be checked had been checked; even if they wanted to dig into forbidden areas, they needed direction.

“Time,” Yu Dazhang reminded them.

“Expand the time frame. Recent social ties are clear—now investigate his past.”

“Ten years ago, twenty years ago. The suspect is forty-three. Even if he entered society at twenty, that’s twenty-three years of social history.”

“I don’t believe he had no acquaintances over all those years.”

Yu Dazhang had made it crystal clear—even Qian Cheng from the tech division understood.

The team member’s face flushed—he was a veteran detective, yet today a newcomer had to remind him this plainly.

It was almost like being taught step by step.

It wasn’t that he was stupid or inexperienced—it was just that this case was too complex.

Complex cases like this require a leader with exceptional intelligence.

Solving crimes is all about brains!

“I’ll get on it right away,” he said, grabbing the other man and rushing out the door.

He couldn’t bear to stay in the room any longer.

“We’re going too,” said the other team.

Before leaving, fearing Yu Dazhang might give them another reminder, one added:

“Don’t worry—we won’t miss a single person connected to Zhang Yan.”

After they left, Lu Zhongxin and another team member went to the interrogation room.

By regulation, at least two investigators must be present during suspect questioning.

After they left, Lu Zhongxin and another team member went to the interrogation room.

When interrogating suspects, investigators must not be fewer than two, as clearly stipulated by regulation.

Finally, only Yu Dazhang and Qian Cheng remained in the meeting room.

“Do I have a mission too?” Qian Cheng asked Yu Dazhang.

“Your mission is equally grueling,” Yu Dazhang said solemnly:

“Go to the Technical Division. If I’m not mistaken, yesterday’s extract is crucial evidence.”

Qian Cheng immediately remembered the black granule extracted from the rental apartment yesterday.

“Could it be…” Qian Cheng’s eyes widened in shock:

“You’ve figured out what it is?”
