Sister, a weak girl will not be weak forever

"Miss Su, today I am going to teach you some self-defense techniques." Qin Yihan said.

"That's great, thank you sister Yihan." Su Ruowei smiled broadly.

"Practice a few moves with me first." After that, Qin Yihan showed the moves.

"Okay." Su Ruowei obeyed obediently.

"Your body is quite flexible." Qin Yihan expressed slight appreciation.

"Well, I used to like dancing. Maybe it's because I practice often." Su Ruo smiled.

"You have the basics. Now I will officially teach you some vicious moves, commonly known as killing techniques." Qin Yihan said.

"Killing technique?!" Su Ruowei shook his head quickly, "I don't want to practice this, it sounds so scary."

"Don't worry, Miss Su. This is the highest level of self-defense. Don't take action unless necessary. Once you take action, it will be a killing move." Qin Yihan said calmly.

"Can I... start practicing from the most basic one?" Su Ruowei said softly.

"No." Qin Yihan denied.

"Why, sister Yihan." Su Ruowei's voice was weak.

"Miss Su, time is tight and the task is heavy." Qin Yibing said seriously.

Hearing this, Su Ruowei almost couldn't help laughing: "Oh."

"This is the best choice for you." Qin Yihan looked at the delicate girl up and down, folded his arms and thought.

"Yeah, hehe." Su Ruowei suppressed her smile.

The cold killer in front of me looks like a stern dean, huh? !

"You have a delicate body. If you learn the Three-legged Cat Kung Fu to face the enemy, you will undoubtedly be seeking your own death." Qin Yihan's expression became meticulous.

Hearing this, Su Ruo couldn't smile anymore.

ah? Is my body really that weak?

Why do both of them feel that they are delicate and weak? !

The girl was secretly crying.

"Miss Su, are you listening to what I'm saying?" Qin Yihan looked at Su Ruowei with his head down in confusion.

"I'm here, sister Yihan." Su Ruowei raised her head and smiled, "Can I ask you a question?"

"Ask." Qin Yihan said.

"Well...how do I practice to be stronger?" Su Ruowei smiled sheepishly.

"Are you talking about strengthening your physique? Or building muscles?" Qin Yihan asked.

"To improve my physique, I don't want to build muscles." Su Ruowei shook his head.

"Okay." Qin Yihan took off his coat and prepared to teach her.

"Sister Yihan, you have a good figure." Su Ruo smiled.

"I'm all muscular." Qin Yihan said calmly.

"I feel that you have a healthy and well-proportioned beauty. I like this kind of healthy beauty." Su Ruowei praised.

Qin Yihan's complexion is wheat-colored, and he looks like he often spends time in the sun doing exercise.

"Thank you, you can practice it too." Qin Yihan said.

"Well, I just want to build some muscles, that's it. If I build a whole body of muscles, I feel weird, and my sister won't like me." Su Ruowei blushed.

"You can go to the gym, there are professional coaches who can guide you." Qin Yihan didn't know what the point of laughter was in this sentence, and couldn't help laughing.

"Hahaha, good idea, sister Yihan, you just laughed." Su Ruowei showed her eight teeth and also smiled.

It's so embarrassing. What did I say just now?

"I didn't." Qin Yihan immediately stopped smiling and turned cold for a second.

"Okay." Su Ruo smiled to herself.

I didn’t expect that killers also have a cute side!

"Miss Su, let's start practicing." Qin Yihan thought for a while and said, "Because it is a killing move, I will first introduce you to the physiological structure of the human body."

"Okay." Su Ruowei found a seat to sit down and listened quietly.

Qin Yihan carried two 1.7-meter and 1.8-meter mannequins from the room and placed them on the floor.

"It's a real human body structure model." Su Ruowei covered her face with her hands.

"Miss Su, don't be shy." Qin Yihan said, "Let's start class now. Let me explain first that I will only say what I say once and will not repeat it a second time."

"Okay, Teacher Qin, let's get started." Su Ruowei took a small notebook and planned to take notes.

"There are several very weak places in the human body that are fatal. They are the temples, the back of the head, the cervical vertebrae, the trachea, and the arteries of the limbs..." Qin Yihan pointed a long gun at the mannequin.

"Teacher, I have a question." Su Ruowei raised her hand.

"Say it." Qin Yihan's face was slightly unhappy.

"In this way, every part of the human body is fatal. The human body is inherently fragile like a reed." Su Ruowei scratched her head, "Isn't that right, Teacher Qin?"

"You are right to say that, but what I am talking about is that in actual combat, you must be the first to give the opponent a fatal blow," Qin Yihan said.

"Okay." Su Ruowei nodded.

"For the parts I just mentioned, in actual combat, you must be quick, accurate, and ruthless. Quick means that the speed of the shot or the instrument must be fast enough. Precision means that the hitting part is as accurate as possible. It is best to kill with one blow. Hard, as the name implies, must be Kill without mercy." Qin Yihan said.

"Wait a minute, teacher." Su Ruowei raised her hand again and asked.

"What's the matter?" Qin Yihan's voice was cold.

"Teacher, are these three conditions indispensable for being quick, accurate and ruthless?" Su Ruowei blinked her eyes in confusion.

"Not necessarily. It can only be said that if you have all three at the same time, it will be absolutely foolproof when you kill your opponent." Qin Yihan said.

"Oh, I understand." Su Ruo smiled and said, "Teacher, please continue."

"Miss Su, please don't interrupt me casually." Qin Yihan's tone was a little impatient.

"Okay, I'm sorry." Su Ruowei said sheepishly.

"There are two models in front of you. They are 1.7 meters tall and 1.8 meters tall. This is to help Miss Su simulate the height of the villain she encounters in life. Miss Su, come up and feel it." Qin Yihan said.

"Okay." Su Ruowei stepped forward and stood next to the model.

"How do you feel?" Qin Yihan asked.

"One is taller and the other is shorter." Su Ruo smiled.

"Which one is more threatening to you?" Qin Yihan asked again.

"The taller ones are scary to look at." Su Ruowei pointed at the model.

"Because of the different heights, different methods must be adopted in actual combat, but the core is the same, which is to master the rules of speed, accuracy and ruthlessness." Qin Yihan taught.

"Oh, thank you teacher." Su Ruowei accepted the teaching humbly.

"For example, the feeling of hugging you from behind is different when you are 1.7 meters tall and when you are 1.8 meters tall." Qin Yihan said.

"Teacher Qin, how tall are you? You feel so tall." Su Ruowei stretched out her hand to compare Qin Yihan's height.

"I'm almost 1.8 meters tall." Qin Yihan said in a cold voice.

"So tall, my sister seems to be about the same height as you." Su Ruowei didn't notice Qin Yihan's bad expression and left to chat with her.

"Miss Su, please listen to the class carefully." Qin Yihan said.

"Teacher, at 1.8 meters, I feel like I am no match for him." Su Ruowei asked again.

"Miss Su, please don't make many assumptions." Qin Yihan put the gun on the table and began to sound impatient.

"But..." Su Ruowei just wanted to speak.

"That's enough, why are you so stupid?" Qin Yihan hit the girl's head hard with his hand and returned to the bedroom.

"I'm sorry, teacher...Sister Yihan." Su Ruowei chased to her door, and was greeted by a loud slamming of the door closing.

Oops, did I make the killer sister angry?
