I traveled through time and space as a villain and became her heart-stealer.

"what?"

Katerina blinked and seemed a little angry.

Gu Qinghan's attitude of giving up is really too arrogant.

"However, I do remember that other people of the opposite sex secretly came to my house the night before last."

At this time, Gu Qinghan happened to answer.

Catalina's eyes lit up and she quickly took out her notebook.

"Who?"

"A beautiful girl with a tall stature, good looks, and heroic spirit."

"Well, please continue..." Catalina bit the pen cap with her little mouth and took notes hard.

"She has great talent and is a top-notch graduate of the Magic Academy."

"When she came to my house, she not only enjoyed delicious and expensive food, but also got drunk..."

Catalina's cheeks turned red at a speed visible to the naked eye.

If you use a thermometer to check, it is very likely that the glass tube has exploded due to the high temperature.

"Okay, okay, stop talking."

Katerina put away her notebook, raised one palm, and sighed with her other hand on her forehead.

The answer from the man in front of her made her feel a little ashamed.

"Please pretend that what happened last night never happened, okay?"

"Oh? Why?" Gu Qinghan smiled playfully.

Catalina whimpered first, then looked away and gritted her teeth:

"As a prosecutor, drinking to the point of losing consciousness during an inspection... is an unheard of joke!"

"I don't want to embarrass myself in front of my colleagues, please."

Gu Qinghan couldn't help but chuckle. He didn't expect this guy to be so straightforward.

Very likable personality.

"What are you laughing at? Is it funny?" Catalina's face turned red and she seemed a little angry.

"Nothing, I was just enjoying the beautiful scenery and couldn't help but be fascinated by it."

Catalina stood there in a daze for a moment, not knowing how to answer.

Then, she turned her eyes and said with a stern expression:

"By the way, you didn't do anything excessive to me when I was drunk that night, did you?"

"How could that be? I don't even remember how you left..." Gu Qinghan waved his hands repeatedly.

"that's fine."

Catalina patted her chest lightly, seeming to be relieved.

Gu Qinghan couldn't help laughing and said slowly:

"Miss, I don't really care whether you get drunk in my house."

"But I can't guarantee that others won't care, such as those tipsters who like gossip."

As he spoke, the smile on Gu Qinghan's face gradually faded, replaced by a calm expression.

Catalina was stunned for a moment, then her eyes turned cold.

"Tell me, what do you want from me?"

She understood the meaning of Gu Qinghan's words in an instant.

Gu Qinghan smiled slightly. It was indeed worry-free to communicate with smart people.

"I want to ask you a question."

"How do you pry open the mouths of criminals who refuse to speak?"

Gu Qinghan smiled calmly, with a barely perceptible light flashing in his eyes.

Chapter 36 (Update!) Katarina's Answer

Catalina frowned when she heard this.

"What do you ask for this?"

The white-haired girl immediately realized the unusualness in Gu Qinghan's words.

This kind of professional knowledge of interrogating prisoners is of no use to ordinary people.

The man in front of me is actually interested in this kind of thing.

It is inevitable that there are some ulterior motives.

"Nothing, I'm just interested in detective novels and want to see if there is any conflict between what is written in the novel and reality."

Gu Qinghan secretly complained that he was really cautious, then stood up and explained with a smile.

"..."

Catalina rolled her eyes at Gu Qinghan and ignored the childish words.

"Forget it. I don't think you would do anything excessive."

Catalina snorted and said slowly:

"In fact, the methods we can use are very simple and can be roughly divided into two categories."

As she spoke, Catalina slowly extended her finger and said in a serious tone:

"First, lure them with benefits."

"If the criminal wants something, then use the benefits to induce her to speak."

"This method is usually effective when used against those who are driven by desire and actively commit crimes."

After a pause, Catalina stretched out her second finger and continued:

"Second, show them the punishment."

"If there is a punishment that the criminal is afraid of, then kill the chicken to scare the monkey and break down her psychological defenses."

"This trick is usually effective when used against people with weak spots."

Gu Qinghan nodded slightly, as if thinking about something.

The suggestions provided by Catalina were actually basically the same as what Gu Qinghan had imagined.

However, relying solely on this kind of thing is not enough to understand the reasons for Lianna's psychological changes.

He needed other clues.

For example, the speed of the attack.

"Of these two methods, which is generally faster?"

After a brief contemplation, Gu Qinghan asked the second question.

Considering Lianna's current hypnotic state, he doesn't have much time left to conquer the girl.

Up to seven days.

The next time Catalina came to check, there was a good chance that Lianna would have fallen completely.

Catalina was startled when she heard this, and then looked hesitant.

"What's wrong?" Gu Qinghan frowned, having a bad feeling.

"If the criminal intends to conceal it, it will generally take a considerable amount of time."

Catalina bit her lip, hesitated for a moment and then said:

"If we calculate it in months, it's a common occurrence."

Gu Qinghan's expression became visibly gloomy.

"You look very anxious." Catalina said with a smile.

"Does my idea seem so obvious?" He blinked in surprise.

Catalina was stunned for a few seconds, then burst out laughing.

"What do you think~"

Gu Qinghan stayed where he was, looking at the top student who was laughing so hard that her body was shaking, and sighed helplessly.

It seems that he is still far behind the professionals.

"Well, after all, this requires breaking down the criminal's psychology step by step, which usually takes a lot of time."

"Breaking down the psychological defenses is a test of endurance. In a sense, it's even a contest to see who will collapse first."

"But there is a way to significantly reduce the time it takes."

As if seeing through Gu Qinghan's anxiety, Catalina beside him raised the corners of her lips, outlining a meaningful arc.

Gu Qinghan's eyes lit up.

"Speaking!"

Catalina nodded with satisfaction, then cleared her throat and said:

"If you can research the other person's information and understand her personality, you may be able to combine the above two things."

Gu Qinghan frowned in confusion.

"Combined?"

"Yes."

Catalina pointed her finger and continued:

"What she hates most and what she wants most are two sides of the same coin."

"If you find this thing, you can reach the other person's heart the fastest."

"And this is the opponent's weak spot."

Gu Qinghan looked at Catalina's expression, as if thinking about something.

Two sides of the same coin.

Thinking back to Lianna's personality changes last night, Gu Qinghan couldn't help but fall into deep thought.

It will take some time to find this thing.

"last question."

Gu Qinghan took a deep breath, stood in front of Catalina with a smile, and looked at the girl in front of him with soft eyes.

"You haven't asked me why I'm asking these questions. Aren't you afraid that I might do something bad?"

Catalina was stunned at first, then she couldn't help but burst out laughing.

"I've never seen a guy who wants to do something bad with such a sad face."

Gu Qinghan stood there, not knowing what to say for a moment.

"In this world, good things are always hard to do. I think solving this painful problem that has caused you so much pain must have some extraordinary significance."

Catalina giggled, then waved her hand, leaving a figure behind.

Looking at the direction she turned and left, Gu Qinghan couldn't recover for a long time.

After a long time, he showed a tired smile.

"Perhaps, she is the one who sees it most clearly."

After seeing Katarina off, Gu Qinghan began to recall the conversation just now.
