Rebirth 2014: I, the King of Criminal Investigation

Chapter 478 Seriously? Even a gentleman is wary.

"You had someone break into my house?!" Liu Hai shouted.

His forehead veins bulged, and he glared angrily at Yu Dazhang.

"Don't get excited."

Yu Dazhang reassured him:

"I wouldn't go so far as to search your house. I just want to tell you that it's too late for you to destroy the evidence now."

He indeed did not allow anyone to search Liu Hai's room.

Out of habit as a police officer, he would not conduct a forced search of a suspect's residence without sufficient evidence.

Are you sure you don't want to drink it?

Yu Dazhang raised his wine glass again:
"If I were you, I'd drink as much as I can now. After today, it might not be so easy for you to drink again."

While he may seem to be urging Liu Hai to drink, every word he says is actually a ploy to get Liu Hai to confess.

After a brief silence, Liu Hai also picked up his wine glass.

He took a deep breath, then tilted his head back and downed the beer in his glass in one gulp.

Yu Dazhang didn't drink it. Instead, he put down his glass, picked up the bottle, and filled his glass again.

Throughout the entire process, his gaze remained fixed on Liu Hai, as if observing his reaction.

None of the three people in the room spoke again.

A moment later, Liu Hai picked up his wine glass again and drank it all in one gulp.

Before Da Zhang could even pour him a drink, Chen Yang had already filled his glass.

They both knew that Liu Hai was going through an internal struggle at that moment.

After another moment of silence, Liu Hai downed the drink in his glass in one gulp.

After downing three beers, his face flushed, but his eyes became much clearer.

"Are you so sure I have the evidence you mentioned in my house?" Liu Hai suddenly asked.

Yu Dazhang shook his head:
"As I said, I don't know much about passwords, so I can't be sure."

If he could really be sure, he wouldn't have come to this dinner.

Some things need to be clarified in person.

"One more question."

Liu Hai glanced at Chen Yang, then turned to look at Yu Dazhang:

"He was clearly more suspicious than me, so why did you end up suspecting me?"

His eyes revealed resentment, doubt, and a hint of bitterness.

"Do you remember the last time we drank together?"

Yu Dazhang looked at him intently:
"When Chen Yang talked about Professor Ying's gossip, you defended her righteously."

“If it’s just casual chatting, there’s no problem with you doing that.”

"But that time you drank quite a bit of both baijiu and beer. Even while drunk, you still tried your best to stay sober and act like a gentleman."

Yu Dazhang continued, his tone laced with sarcasm:

"To be a person like you is just too fake."

"You think you've done everything perfectly, without leaving any room for error, but in my eyes, every move you make and every word you say is full of flaws and loopholes."

He actually exaggerated.

He didn't realize it when he was drinking, but discovered it later when he recalled the incident.

But it doesn't matter, no one will notice these details if we say them now.

Upon hearing these words, Liu Hai's expression turned strange, as if to say: "No way, even a gentleman is wary."

Chen Yang, standing to the side, also wore an expression of disbelief.

The last time they drank together, he argued with Liu Hai until they were both red in the face. At the time, he didn't think there was anything wrong with it, but now that he thinks about it, it was definitely not normal.

Even after drinking so much, Liu Hai actually became more and more serious.

In short, it's unscientific.

"Until this afternoon, I only had doubts about you."

Seeing that Liu Hai's eyes were fixed and his expression somewhat blank, Yu Dazhang pressed his advantage and said:
"But when the gun went off, everyone else's faces showed only bewilderment and panic, while you were the only one trying to remain calm, but the fear in your eyes was impossible to hide."

If he only looked at Liu Hai, he might not have been able to make a decision.

But when compared to those around them, the difference becomes too obvious.

Having said that, Yu Dazhang stopped beating around the bush and got straight to the point:

"Now that we've already identified you, whether we have evidence or not is no longer important. Do you think you can fool the National Security Bureau?" "Believe me, they have plenty of ways to make you tell the truth."

"Even those specially trained agents couldn't make it, so you're even less likely to succeed."

He paused briefly, seemingly giving Liu Hai some time to consider his words, before continuing:

"Besides, you've already been exposed."

"If I'm not mistaken, the codebook in your room is a storybook."

"This is both concealed and allows for an infinite number of unique characters, because each character has multiple different codes."

Yu Dazhang had heard that the encryption method of Chinese codebooks was the most complex.

The two parties secretly agreed to transmit a book by translating the Chinese characters into numbers according to page number, line number, and word number.

Because many of the same words appear in a storybook.

Therefore, there is no pattern to it at all.

For example, the word "I".

It will definitely appear multiple times in any storybook.

Therefore, the same character can be encoded differently each time.

"You, how did you know?"

At this moment, Liu Hai was completely dumbfounded, looking at Yu Dazhang as if he were a monster:

"You even know what I'm thinking."

Is it really necessary to make such a fuss? Yu Dazhang believes that this deduction is not difficult at all.

As the saying goes: cleverness can backfire.

If Liu Hai had written Chinese characters directly on the note, he really wouldn't have had a chance to find out.

Just find any printer, print the message you want to send out on paper, and even if it's discovered, no one will know who did it.

But Liu Hai insisted on playing a trick, creating a digital cipher.

He may have thought this would increase the security of information transmission, but in reality, it became his biggest mistake.

Because of this, the codebook in his room became the most direct evidence.

That's why people say that being too smart isn't good; you can easily make things worse by being too clever for your own good.

"Stop struggling."

Yu Dazhang advised:
“I respect you as a scholar, which is why I’m trying to save you some face. You should know very well what the consequences would be if I handed you over to the National Security Bureau directly.”

He wasn't really trying to scare Liu Hai.

All you need to do is find the codebook in Liu Hai's room and match it with the ciphertext on the note.

At that time, he will be greeted with a "warm welcome" from Beijing Guoan.

Why not just do it this way?
Because Yu Dazhang has his own methods for handling cases.

Handing it over directly to the National Security Bureau would be a shortcut for him, but there are no shortcuts in handling cases.

This time, Liu Hai thought for a full ten minutes.

Yu Dazhang wasn't in a hurry; he knew Liu Hai would figure it out.

"Am I going to die?"

Liu Hai suddenly looked up and asked this question.

"I don't know either," Yu Dazhang said honestly.
"This should fall under the category of espionage. I haven't dealt with this before, so it's hard for me to make a judgment."

Seeing Liu Hai staring blankly at him, Yu Dazhang added:

"However, based on my experience as a police officer, no matter what the crime is, the final verdict must be determined based on the specific circumstances."

"If someone performs meritorious service, their sentence can definitely be reduced."

He was still trying to persuade Liu Hai to confess and receive leniency.

At times like these, a person's mind is often confused, and the addition of alcohol can further dull their thinking.

In Yu Dazhang's view, this was a good opportunity to take advantage of the situation.

"We've known each other for a while now, so you still have a chance to back out here. But if Guoan takes over..."

Before he could finish speaking, Liu Hai interrupted him:

"I have a condition."

“Go ahead,” Yu Dazhang immediately agreed.

"As long as it's not excessive, I will do my best to satisfy you."
