I'm in Detective Conan, and I start with the Grand Theft Auto system.

So the next afternoon.

Xiaolan took out her phone from her pocket, glanced at the address, then looked up at the house number of the villa in front of her, and paused for a moment.

She knew this place all too well!

This villa is near Shin-chan!

When she was a child, she would pass by this villa countless times when she came to play at Shin-ichi's house. At that time, the house was always empty. She never thought that one day she would walk through this door because of "teaching karate".

"What a small world!" Xiaolan exclaimed as she pressed the doorbell, and the door opened quickly.

Lin Shen appeared at the door wearing a gray tracksuit, looking like he had already warmed up and prepared. He stepped aside to make way for him and said with a smile, "Come in."

Xiao Lan followed him through the entrance hall and corridor, into a huge room inside the villa—an open-plan fitness space of over 100 square meters.

The floor was covered with brand-new non-slip training flooring, and a sandbag that looked like it hadn't been used much stood in the corner. Next to it, on a shelf, were several pairs of dumbbells of different weights and yoga mats.

A row of storage cabinets was placed on the side near the floor-to-ceiling window, making the whole space spacious, bright, and well-lit.

Lin Shen pointed to a door in the corner: "The changing room is over there. You can change your clothes in there."

Xiaolan nodded and went into the changing room.

When she came out of the locker room, Lin Shen was stretching in the center of the field. Hearing footsteps, he looked up and his gaze lingered on her for a moment.

Xiaolan changed into a white karate uniform, with a black belt around her waist symbolizing her rank. She looked completely different from the girl who had been wiping tables in a coffee shop in a maid outfit just a few dozen minutes earlier.

When she wears a maid outfit, she is a gentle, lovely, and irresistibly seductive coffee shop employee.

But the moment she put on the taekwondo uniform and tied on the black belt, her entire aura changed. She became heroic and stood tall and strong!

Lin Shen felt that his enthusiasm for learning had indeed been aroused.

He clapped his hands with a smile and said, "Come on, Teacher Xiaolan. Teach me the very basics first."

Xiao Lan's ears started to burn again when he called her "Teacher Xiao Lan".

But she quickly composed herself, took a deep breath, walked up to him, and cleared her throat: "Well... let's start with the most basic punching motion."

She stood beside him and demonstrated the movements, slowing down so he could see every detail clearly: "Your hand should be like this—pushing out from your waist, not just using the strength of your arms, but using the rotation of your waist to drive your entire upper body. Look, like this—"

She demonstrated a slow and precise punching motion, "and then, at the moment of punching, you need to twist your waist, transferring the power from the soles of your feet all the way to your fist. Try it."

Lin Shen followed her movements several times, and at first he did look quite good.

Xiaolan carefully observed his posture, occasionally tapping his shoulder or wrist with her fingertip to correct any deviations in angle: "Relax your shoulders a little... Yes, don't clench your fist too tightly, only exert force at the moment of punching—"

For the first few minutes, it really looked quite professional.

But I don't know from which action it started, the atmosphere began to change.

While practicing a "punch and turn" move, Lin Shen deliberately turned a little more than half a circle, and his arm naturally wrapped around Xiao Lan's back, pulling her directly into his arms.

Then he lowered his head, leaned close to her ear, and asked in a low voice with a smile, "Is it like this? Can you help me check if my movements are correct?"

Xiaolan's body froze for a moment.

She could clearly feel his body temperature seeping through the two layers of clothing, and his breath brushed against her earlobe, carrying a warm breeze.

A current shot from the tip of my ear all the way down the back of my neck, and then quickly spread across my entire face.

Her ears turned bright red, and even her neck flushed pink.

Like a cat whose tail had been stepped on, Xiaolan abruptly broke free from his embrace, took two steps back, her face flushed with embarrassment, and her voice carried a hint of coquettishness that she herself was unaware of:

"President Lin!! You...you should concentrate on practicing!!"

Lin Shen smiled happily at her reaction.

He changed the subject: "Just practicing the moves is too boring. How about we get straight to actual combat?"

Xiaolan paused for a moment, looking at him hesitantly: "Practical application? You've only been learning for less than twenty minutes..."

Lin Shen patted his chest, looking confident: "Practice makes perfect! You'll learn as you go."

Looking at his fearless attitude, Xiaolan secretly thought that she should teach him a little lesson so that he would know what it means to "lose the foundation and the world will shake".

She nodded, took two steps back to create some distance, then slightly separated her feet, assuming a very standard karate starting stance, her gaze calm and focused as she looked at Lin Shen: "Let's go then."

Without a word, Lin Shen rushed forward and threw a punch at Xiao Lan.

His movements were completely haphazard, purely relying on speed to recklessly charge ahead.

Xiaolan easily dodged his punch by turning to the side, then seized the opportunity when he had exhausted his old strength and had not yet generated new strength, and cleanly took a step forward, punching him right in the center of his chest.

The moment her fist touched his chest, she restrained herself and pulled back her strength to make sure there was no pain.

Then Lin Shen stopped practicing martial ethics.

After taking the punch to the chest, he didn't retreat but advanced, grabbing Xiaolan's taekwondo uniform sleeve and using his waist to throw her over his shoulder.

His movements were large and his momentum was strong—but he was not skilled enough and did not have a good balance. While he knocked Xiaolan over, he also fell down because he lost his balance. The two of them fell onto the training mat one after the other.

And unfortunately, he landed right on top of Xiaolan.

The two of them were stunned at the same time.

Lin Shen looked down at Xiao Lan, who was pinned beneath him—her face was flushed, her eyes filled with a mixture of embarrassment, annoyance, and surprise, and a few strands of her hair had come loose from the rolling around and were sticking to her cheeks.

Her breathing was slightly rapid, her chest heaving, and the collar of her taekwondo uniform had loosened a little from her movements.

Lin Shen did not get up immediately.

He deliberately stopped there, looked down into her eyes, a slight smile on his lips, and said in a low voice, "You've already fallen? Show me some strength, Teacher Xiaolan."

Xiaolan was both ashamed and angry at his words.

In that instant, her eyes transformed from shame and annoyance into a genuine competitive spirit!

The temper that had won her the Kanto championship was finally ignited!

With a sudden burst of strength from her waist, Xiao Lan nimbly locked Lin Shen's arm with her legs, then used her core strength to flip and twist, cleanly and neatly throwing Lin Shen off her.

Although it wasn't particularly brutal, the movement was crisp and clean, full of power and skill.

Lin Shen completely lost his balance, rolled half a circle on the mat, and finally lay face down on the mat in a rather ungraceful posture.

He lay there, stunned, for a second or two.

Then he laughed.

This time, it was a genuine, heartfelt laugh.

Lin Shen pushed himself up from the ground, dusted himself off, and his eyes gleamed with an excited anticipation: "Good! That's more like it! Come on, don't hold back, don't worry about hurting me!"

Xiaolan stood opposite him, her face flushed slightly, her chest rising and falling gently from the exertion she had just exerted. She bit her lip lightly, the burning flame in her eyes still unextinguished.

She readjusted her starting stance, her voice laced with a stubbornness squeezed out through clenched teeth: "Fine... that's what you said!"
