Buda Hiroaki said coldly, "I understand you're eager to investigate the case, but your actions are somewhat contrary to common sense."

After saying this, Hiroaki Buta ignored the two people's reactions and walked towards the teaching building again.

"Professor, please wait a moment!"

Tang Ze walked up to the other person and asked politely, "Excuse me, what did you do last night during that precious time that is indispensable to middle-aged men?

I remember yesterday was Thursday, and you unexpectedly came home quite early."

Hearing Tang Ze's words, Bu Tian Hongming frowned and looked at Tang Ze and said: "I know that you two are actually suspicious of me..."

"No, no, how could that be..."

Hearing the other party's blunt words, Takagi quickly waved his hands to deny it, but was interrupted by Hiroaki Buta: "No need to be polite, don't forget that I'm a psychologist."

"Yes, we do doubt you, Professor."

Hearing what Hota Hiroaki said, Tang Ze smiled calmly and said, "After all, according to our current investigation, only Professor Hota and Miss Iimori are close friends."

"But she drank the poison herself, knowing clearly that it was highly toxic. What do you think this is if not suicide?" After saying this, Hiroaki Buta walked straight towards the teaching building in front, obviously not wanting to talk about this topic anymore.

Obviously, coupled with the unauthorized visit to the other party's home last night and the investigation of the other party's actions in the morning, the two sides have completely torn their relationship apart.

This also made Tang Ze no longer have any scruples. He followed closely behind Buda Hiroaki and said with a smile as if inviting him to an afternoon tea party: "I think if the professor goes back to the Metropolitan Police Department with us, I think we should be able to solve some problems.

"I refuse. I don't have time to drink tea with you." Buda Hiroaki said coldly, "Detective Karasawa, let's end the reasoning game here.

If you really suspect that I am the murderer, then please show me the evidence. Didn’t you also say in lecture that there is no “perfect crime”? There must be a flaw in some link.

Then please find the flaw and show it to me!

If we find it, I will go with you, whether it’s the Metropolitan Police Department or somewhere else.”

After saying this, Hiroaki Buta ignored the two of them and left quickly.

But this time, Karasawa and Takagi did not catch up.

What he said just now was very rude, and it also meant that the "face" maintained between the two parties was completely torn apart.

If I continue to pester him now, I would be in the wrong.

Of course, Tang Ze was not too worried about the two sides "falling out".

Before, we were still in the process of investigation and trial, so naturally we had to maintain a good relationship, but now

There is no need for that anymore.

The confrontation between the two sides was entirely verbal and psychological.

At the beginning, Tang Ze had the upper hand and tested the other party's suspicion.

But as Tang Ze continued to test him, the other party saw that he could no longer hide the truth and chose not to "break up" directly.

In the previous conversation, after the other party knew that the two people suspected him, he had no intention of continuing to conceal it. He told the two people very directly that he would talk about it after they found evidence.

This attitude is no different from admitting that he is the murderer, but it is troublesome to still do so.

He knew that he was under criminal suspicion, but he still said so arrogantly. He is either stupid or confident that he will not be caught.

And it is obvious that Hiroaki Hota is not a fool. He can say such words, so he must have made full preparations to deal with the search.

And this is indeed the case. When Tang Ze and his friends returned to the room for the second time to get Saki Iimori's notebook, they checked the room again, but still did not find anything suspicious.

This is also the source of the other party's confidence. He is confident that nothing he does will leave any evidence.

This is a tough opponent, and he is even sure that his methods can commit the perfect crime.

"What should we do now?"

Takagi looked at Hiroaki Hota walking away with a worried look on his face. "We've already identified the suspect, but we can't produce a single piece of evidence. We don't even know how he poisoned Saki Iimori..."

"I met a tough opponent..."

Tang Ze frowned and returned to the car with Takagi. The two sat quietly in the car and began to think.

The most crucial point now is how Hiroaki Buta managed to poison without any external invasion?

But the bottle of poison on the bedside table was marked "highly poisonous". How could Hiroaki Buta make Saki Iimori take the poison willingly?

Tang Ze felt vaguely that he seemed to have overlooked something, which was the key to unlocking this technique...

Without further hesitation, Tang Ze took out a [Wake-up Cigarette] and lit it.

When the smoke entered his lungs and was exhaled, Tang Ze's brain, which was already running at high speed, began to speed up again.

Memories began to emerge in his mind one by one. Every conversation between the two parties after they met was like a movie, playing back in Tang Ze's memory palace.

The scene soon switched to the part where he and Officer Takagi went to the classroom to listen to Hiroaki Buta's lecture.

"This observational learning is the 'physical perception method'..."

"Children will imitate adults' pretentious words..."

When these two sentences seemed useless and the lecture content flashed through Tang Ze's mind, he suddenly realized something.

"I see...it's an imitation..."

Tang Ze murmured softly on top of the car.
