Chapter 192: Beating the Grass to Startle the Snake

There are many types of laboratories, all kinds, including chemistry, physics, biology, and so on.

He must first determine exactly which type it is.

"A biomedical laboratory."

Liu Miao said this, took out his phone, scrolled through it, found a photo, and then held the phone screen up to Yu Dazhang:

"Look, this is the laboratory. It is a national key laboratory, affiliated with Jin Ling University."

Not in Songhai? Yu Dazhang looked closely at the photo on the phone screen; indeed, the words "Jin Ling University" were visible.

Jin Ling is three hundred kilometers from Songhai; this distance is not far for someone like Liu Qi who flies frequently.

Even by car, it could be reached in just over three hours.

Liu Qi had donated only once, and it was to a laboratory related to medicine.

Could such a coincidence exist?

Most importantly, the time of the donation occurred exactly nine days before Liu Zhengyang's death.

So much could be done in these nine days.

If it were a laboratory of another type, Yu Dazhang would not be so suspicious.

Such an important clue certainly cannot be overlooked.

"You must go on a business trip." Yu Dazhang pointed at Liu Miao's phone screen:

"Go to Jin Ling University and investigate whether Liu Qi had any business dealings with this laboratory."

"Or rather..."

"Whether Liu Qi made some kind of transaction with this laboratory in private."

If this clue is verified, it will be a huge surprise.

Since taking over this case, all Yu Dazhang has been doing is finding clues, reasoning, investigating...

And the ultimate goal of doing all this is to find evidence.

Without finding actual evidence, no amount of reasoning is useful.

Liu Miao was already following the Liu Qi line; hearing Yu Dazhang's order, he immediately understood the meaning behind his words.

"I will set off immediately."

He was also a decisive person; after speaking, he stood up to prepare to leave, but just before going out the door, he turned back and asked hesitantly:

"Should we investigate secretly, or reveal our identity?"

"No need to make it so complicated." Yu Dazhang smiled:

"Just investigate directly in the capacity of police; if conditions allow, try to make as much of a stir as possible."

After hearing this, Liu Miao paused for a moment, then thought of something and smiled as well:

"You are deliberately trying to startle the snake by beating the grass."

Quite sharp... Yu Dazhang smiled and nodded.

Speaking with a smart person is easy; no need to laboriously explain. With just a slight hint, the other person understands your meaning.

After Liu Miao left, Yu Dazhang opened his small notebook and marked a plus sign next to Liu Qi's name with a pen.

The scope is gradually narrowing... he calculated in his mind.

If previously the suspects were locked in among Liu Qi, Liu Siyuan, and the butler,

then now only two people remain.

The siblings Liu Qi and Liu Siyuan!

The butler, as a pawn, can already be ruled out.

At present, Liu Qi is the most suspicious.

The last words left by Liu Zhengyang before his death all came solely from Liu Qi's mouth; they were entirely her one-sided account.

Furthermore, the subsequent matters regarding the distribution of the estate were handled entirely by her.

Although on the surface, this distribution of the estate seems to have no improper aspects.

In fact, Liu Qi even suffered some losses in it.

But precisely her unusually generous behavior is what arouses suspicion.

And that one donation act of hers was clearly purposeful.

The reason the investigating officers previously did not find this lead.

First, Liu Qi had no motive for murder.

Moreover, she was the one who reported the case; if she had not called the police, this case would not have been filed at all.

Second, the previous officers did not discover the fact of the drug substitution. Only by confirming that the medication Liu Zhengyang took had been swapped or replaced by someone would suspicion arise regarding Liu Qi's donation to a drug laboratory.

Otherwise, at best, it could only be considered an ordinary social donation activity.

It is still a bit of a stretch... Yu Dazhang thought and thought, realizing he was still at the very beginning stage of the case.

Assuming Liu Qi is indeed the murderer, what is her motive for killing?

First, revenge killing is ruled out.

He was her biological father; blood is thicker than water. Even if there were conflicts between the two, it would not reach the point of wanting to put him to death.

Moreover, the previous officers investigated and found that the relationship between father and daughter had always been very good.

Seeking wealth can also be ruled out.

The distribution of the estate was handled by her; everything has legal validity.

If she wanted to seek wealth, Liu Siyuan would not be able to compete with her.

What confuses Yu Dazhang the most is why Liu Qi voluntarily reported the case?

If she is the murderer, what benefit does doing so bring her?

Still the same saying: people act with a purpose.

No mistake, one sentence, one release, one content, all in one read!

Precisely because of this, the officers who handled the case earlier did not suspect her.

"It seems getting answers from you is impossible."

Yu Dazhang muttered, fixed his gaze on the notebook, and after some thought, drew a horizontal line beneath the name Liu Siyuan.

"Only you can help me find the truth."

Taking out his phone, he paused to think for a moment, then called Liu Siyuan.

The call was answered quickly.

"Why is it you again?"

Liu Siyuan's voice sounded somewhat impatient, carrying a hint of disbelief.

It seemed Yu Dazhang should not have contacted him again.

"It's me, it's me, hehe."

Yu Dazhang's attitude was very good; his tone was even a bit obsequious, as if he were asking the other party for a favor:

"The case has made new progress, so I must trouble you to cooperate with the investigation once more."

"Progress?" Liu Siyuan's tone changed immediately; he asked in surprise:

"Was my father really killed by someone?"

Hearing this, Yu Dazhang frowned.

Liu Siyuan's reaction was too slow.

They had the same parents; how could he differ so much from Liu Qi?

Your father has been dead for over a year, yet you never suspected anything.

"We cannot confirm it completely yet," Yu Dazhang explained patiently:

"So we need to learn some details from you. You know, when handling cases, we cannot speak too definitively."

The meaning in his words was already very plain.

Your father was indeed killed, but we cannot say it directly.

If Liu Siyuan could not hear such an obvious implication, then his intelligence truly had a problem.

"Fine, come to my house again."

Liu Siyuan agreed readily this time, without any delay, and immediately added:

"But it must be in the afternoon; I have to go to the airport to pick someone up in a while."

Hearing that he would personally go to pick someone up, Yu Dazhang secretly rejoiced, yet spoke in a neutral tone:

"Fine, I'll wait for your call this afternoon."

He could already guess who Liu Siyuan was going to pick up.

Zeng Lisi.

The woman who made Liu Siyuan give up the entire forest.

Now only she could make Liu Siyuan go pick her up personally.

This is knowing oneself and knowing the enemy.

Without Ma Jian's prior investigation into Liu Siyuan's social connections, Yu Dazhang would not have reached this conclusion.

This time it was truly a fortunate coincidence.

Just the right opportunity to meet this woman.
