Chapter 185: The Common Flaw of Clever People

Still, this trip to the hospital wasn't entirely without gain.

At the very least, he now knew the other party had exploited the properties of "verapamil" to carry out the crime.

Back at the squad.

He opened the notebook again, looked at the names listed one after another, and his brow furrowed tighter and tighter.

There were far too many suspicious points in this case.

Although it looked like some progress had been made, they were still a long way from actually cracking it.

Now that it could be confirmed that Liu Zhengyang had been killed by someone.

Another key question could be considered.

What was the killer's motive?

Or rather, what did killing Liu Zhengyang gain for the killer?

Such an ingenious scheme could never have been conceived in a day or two, no matter how clever the other party was.

It was like a row of dominoes—every step had to be taken with extreme care, or it would set off a chain reaction.

The servants and the butler could be ruled out as suspects at this stage.

First, Liu Zhengyang's death brought them not the slightest benefit.

Second, these people didn't have that kind of intelligence either.

Anyone with the ability to set up such a scheme wouldn't be working as a servant in the Liu household.

Only two kinds of people could gain real benefit.

1. Liu Zhengyang's children.

Liu Qi and Liu Siyuan, the brother and sister, were both born to Liu Zhengyang and his first wife—true flesh and blood, and naturally the legal heirs to the estate.

In the country, cases of people brutally murdering their closest kin out of greed for a huge inheritance were not uncommon; it was nothing new.

Moreover, Liu Zhengyang had lost his wife early on, and apart from these two, there was no one else to inherit the estate.

2. Business competitors.

The business world was like a battlefield.

A business tycoon like Liu Zhengyang inevitably had many business rivalries and entanglements with others.

And eliminating a competitor was the quickest and easiest way.

"Liu Siyuan was quite resistant toward the police."

Yu Dazhang recalled the scene of his earlier conversation with Liu Siyuan.

The man didn't give him the impression of being scheming.

Whatever was on his mind, Liu Siyuan would show through his expressions and body language.

How to put it.

He was very much like that famous rich second-generation kid in the country, Comrade Xiao Wang.

On the surface he looked unruly and untamed, but in reality he just couldn't control his own thoughts and temper.

This kind of person had no depth; every emotion was written all over his face.

Could Liu Siyuan be faking it?

Hard to say.

To get the inheritance, putting on an act was perfectly normal.

Some people and matters still needed further confirmation… Yu Dazhang picked up his pen and drew a plus sign after Liu Siyuan's name.

Then he thought for a moment—there was one thing in the case file that hadn't been written down.

The method of inheritance distribution.

This belonged to the Liu family's private affairs.

If it couldn't be determined that he had been murdered, investigating the Liu family's inheritance distribution was truly unnecessary.

But things were different now—Liu Zhengyang had very likely been killed because of the inheritance.

Not enough hands… Only now did Yu Dazhang realize that a three-person investigation team was really far too inefficient once they actually got moving.

Investigating a single matter often required two people, and to investigate thoroughly took a great deal of time.

It's only been a few days and he's already become a lone commander.

Taking out the case file, Yu Dazhang flipped directly to the page recording information related to Liu Qi.

Liu Qi, female, 28 years old, from Songhai, once studied Natural Sciences at Cambridge University, returned to China in 2010, currently employed at Zhengyang Group as Senior Vice President.

A very impressive personal résumé.

When Yu Dazhang first saw it, four characters immediately surfaced in his mind: a child favored by heaven.

Compared with his elder sister, the younger brother Liu Siyuan's personal résumé was considerably simpler.

Liu Siyuan, male, 26 years old, from Songhai, junior college graduate, unemployed.

That's all.

Yu Dazhang even suspected the officer in charge of recording had been going through the motions.

Logically speaking, with the Liu family's wealth, even if they had to throw money at it, they could have piled up a decent diploma for Liu Siyuan.

Yet Liu Zhengyang stubbornly refused to do that.

In Yu Dazhang's view, this pair of siblings in the Liu family was steeped in strangeness at every turn. Even Liu Zhengyang's way of handling things felt odd.

One family had somehow produced two completely different kinds of children—and both were his own.

Finding Liu Qi's phone number, Yu Dazhang dialed it.

As the person who reported the case, Liu Qi's contact details were also recorded in the case file.

The phone rang a few times before being answered.

"Who is this?" A crisp, capable female voice came through the receiver.

"Hello, I'm from the Songhai Hongkou Branch." Yu Dazhang quickly stated his identity, then immediately shifted his tone:

"Regarding your father's sudden death a year ago, I'd like to meet you in person to understand the situation."

Upon hearing that, there was silence on the other end for two seconds, then a question:

"Is a meeting necessary? Can't we make things clear over the phone?"

This situation was something Yu Dazhang hadn't expected.

No mistakes, one sentence, one release, one content, all in one place!

Could Liu Qi have something to hide?

Otherwise, why wouldn't she dare to meet?

"I think it's better to chat in person. Besides, I've already met your younger brother, and he was very cooperative."

Yu Dazhang deliberately compared Liu Siyuan with her.

The more she didn't want to meet, the more necessary it became.

If Liu Qi still insisted on not meeting, then Yu Dazhang would list her as a primary suspect.

Unexpectedly, when Liu Qi heard he was actually comparing her to Liu Siyuan, she immediately got angry.

"Can I be compared to him? He does nothing all day, just lies at home eating, drinking, playing, and enjoying himself, with plenty of free time."

After speaking, she paused slightly, as if trying to calm her agitated emotions, but immediately continued complaining:

"Whereas I work late every day and frequently go on business trips."

"I would like to talk to you in person, but the problem is I'm not even in Songhai right now. If you can wait, then wait until I return to Songhai tomorrow and contact you."

So she wasn't in the local area... After hearing Liu Qi's words, Yu Dazhang couldn't help but feel a wave of disappointment in his heart.

He had thought he could lock onto a key suspect this time, but it turned out the person was just on a business trip and not in Songhai.

At the same time, he also heard that Liu Qi didn't have much affection for her younger brother.

The brother and sister both made no secret of their mutual disgust and hostility.

Upon sudden contact, both gave the impression of having no scheming nature.

In terms of personality, the brother and sister were quite similar.

"Then it's settled. I'll wait for your call tomorrow."

After ending the call, Yu Dazhang checked the investigation report on Liu Zhengyang's death scene from a year ago again.

He had already read this report many times.

But now with new clues, he wanted to see if there were any oversights or omissions.

Besides Liu Zhengyang, fingerprints of Liu Qi, Liu Siyuan, the butler, and two other servants had been collected in the study.

The police officers who investigated previously had also looked into this.

The butler and servants stated that the study was cleaned and wiped every day, so even if there were fingerprints, they were left that same day.

Moreover, after Liu Zhengyang's death, it was normal for the Liu siblings and the family's butler and servants to enter the study.

No suspicious points could be found in this aspect either.

"The opponent is someone who likes to set up schemes, planning three steps ahead for every move..."

Yu Dazhang muttered while his gaze roamed over the investigation report:

"Liu Zhengyang's death scene, such an important place, you would definitely leave traces favorable to yourself."

"What would a perfectionist leave in such a place?"

Moments later, his gaze fell on a line of text in the report.

Putting down the investigation report, Yu Dazhang recalled the statements made previously by the butler and servants in his mind.

After learning of Liu Zhengyang's incident, Liu Siyuan and Liu Qi entered the study one after another, followed immediately by the butler...

After that came the medical staff and the police.

That is to say, the fingerprints of those two servants were left while they were cleaning.

Combining the fact of the substitution to analyze, only three people had the opportunity to switch the drugs back.

Liu Qi, Liu Siyuan, the butler...

Thinking of this, Yu Dazhang picked up the investigation report again, his gaze falling on that line of text once more.

This time, a confident smile appeared on his face:

"As long as one is a smart person, there is a fatal weakness..."

"Cleverness is one's own undoing."
