Chapter 1

Chapter 1: Su Yang

Two figures sat on the highest point of the Eternal Retribution Cliff, one old man and the other a handsome man with otherworldly features. The old man emitted an ancient aura that caused the surrounding space to twist and turn, and the young man casually sat beside him, looking as though the heavy atmosphere did not bother him at all.

“Young man, what crimes have you committed that got yourself stuck in this gloomy place? You do not look like someone who belongs here…” The old man asked, his gaze filled with interest as he looked at the young man, who was surrounded by a noble aura that calmed the space surrounding him.​​ 

The young man showed a slight smile. “I have done many things in this life, one such as devouring the forbidden fruit created by His Majesty, the Heavenly Emperor,” he said in a calm voice.

The old man lifted his brows in surprise, and his gaze flickered with shock as he looked at the young man. Despite the vague explanation, he instantly understood what the young man was trying to say.

“You… you… you…” Unsure of what to say, the old man stuttered nonstop. To be shocked speechless, this was a first even for someone as ancient as him, not to mention his wide eyes that hadn’t been this wide for countless years.

“I’m more surprised that you are still alive after all that than what you’ve done!”

The young man only smiled at his words.

Suddenly, the old man burst out laughing: “I can already imagine the raging face of the Heavenly Emperor when he first heard the news! Ahahaha! Young man, I have taken a liking to you! What is your name?”

The ancient aura surrounding the old man had long disappeared. He looked and acted more like a kind grandpa than anything now.

“The name’s Su Yang,” he responded.

“Then Su Yang… would you like to leave this place?” The old man suddenly grinned, showing his two rows of yellow teeth.

Su Yang turned to look at the old man’s face for the first time; it was filled with wrinkles, almost like a dried-up fruit. However, despite his ghost-like face, his eyes were as clear as water, and they shone brighter than the brightest stars in this eternal night sky.

“What’s the point?” Su Yang said a moment later: “Even if I can leave this place, it will only trigger the Heavenly Emperor’s anger even further. I think I prefer sitting here until my soul rots away than having to constantly deal with the Heavenly Emperor’s wrath.”

“What if I say that you can leave and not have to worry about the Heavenly Emperor?” The old man kept the grin on his face, but deep in his gaze flickered a profound light.

“Then what? What should I do after leaving? Continue living the sinful life that I have been living for the past thousands of years? Or take revenge on those who wrongly accused me?”

“That… is up to you.”

Su Yang suddenly reached his hands towards the night sky and made a grasping motion, almost as if he wished to grab ahold of the stars shining above. “Then… if I one day decide to leave this place, I will…” He suddenly stopped talking and smiled: “Forget it. I think I’d still rather be lazy in this place until I die.”

The old man suddenly started laughing again: “You are still too young to completely hide your desire from this ancient one, Su Yang! Even if you stay here for all eternity, can you really die from old age? An immortal such as yourself? Hehehe… your wish… I shall grant it!” He suddenly stood up and waved his sleeves, and the night sky that hasn’t changed since the creation of this Eternal Retribution Cliff suddenly turned to day, bewildering every soul that dwelled there.

“You… who are you?” Su Yang stared at the grinning old man with wide eyes.

The old man said: “Just an old man with nothing better to do. Right… before I send you away, I’d like to thank you for what you did.”

“Thank me…? What do you mean by tha–”

Before Su Yang could ask the old man why he was being thanked, a bright white light suddenly engulfed the world, taking away his vision.

Immediately after getting blinded by the white light, Su Yang felt a sharp pain near his heart, like he had just been stabbed by a sword. He snapped his eyes wide open to see a handsome young man with a vicious grin on his face, standing in front of him on a wide stage, and in his grasp was a steel sword.

“Che. I narrowly missed his heart,” mumbled the handsome young man.

Su Yang looked down to see a sword penetrating his body, and he instantly became alert.


Within Su Yang’s body suddenly exploded an overwhelming aura filled with killing intent, causing the handsome young man before him and the dozens of people surrounding their stage to cough up a mouthful of blood.

And because the handsome young man was standing so close to Su Yang, he directly fell unconscious after coughing up blood.

The place instantly turned dead silent, and Su Yang pulled out the sword that was still stuck in his chest, ignoring the pain.

After taking the sword out of his chest, Su Yang took this moment to quickly search through his memories.

In his memories, he found out that he was inside the body of a young cultivator with the same name as his – Su Yang, and that he has the exact same looks as his younger self. However, the similarities stopped there and everything else was different. His cultivation base was near non-existent when compared to his old cultivation base, and he is currently a disciple in this Profound Blossom Sect – a sect that heavily focuses on dual cultivation – where two people of the opposite gender indulge in sexual practices for cultivation! It is almost as if he had traveled back in time to when he was just a young boy who had recently started cultivating!

As for how he got into this situation, the ‘Su Yang’ before him had gone to court a female disciple named Xing Xing and ended up offending her current partner, Yan Ming, the now unconscious handsome young man before him, which resulted in a deathmatch between them.

“What in Heaven’s name is happening?! How did I get here? What happened to the Eternal Retribution Cliff?!” Su Yang suddenly recalled how the old man in the Eternal Retribution Cliff had said that he will help him leave the place.

“Did he send me back in time… No… I don’t recall ever becoming a disciple of this Profound Blossom Sect… Then…”

In the midst of Su Yang’s thoughts, a loud shout suddenly broke the silence. “Everybody halt your movements!”

A middle-aged man jumped onto the stage and looked at Su Yang and the unconscious Yan Ming with a frown. “Who authorized the two of you to have a deathmatch today? Scram before I call for the disciplinary squad!”

“Yes, Elder Sun!” The disciples around the stage hurriedly scrambled away, leaving only Su Yang and Yan Ming on the stage.

Su Yang decided to leave this place first and ponder later. Before he jumped off the stage, the middle-aged man called Elder Sun looked at him and said: “What’s your name?”

“Su Yang,” he replied in a calm tone.

Elder Sun nodded and no longer looked at him and directly went to pick up the unconscious Yan Ming to take him away.

After leaving the stage, Su Yang searched through his memories and began walking towards his living quarters.

Read My Review of Stealing Spree

Note: Netori warning—-  the netori part of the novel isn’t that prominent. We just know he had stolen some girls. The main focus of the story is his development and the girls around him. Please do note that this is my opinion based on the first 100 chapters I read.

Chapter 1

Chapter 1: New School, New Target


I could be what you called an ordinary student. Or on anime terms, the Classmate A. I have neither the attention nor popularity. But despite that, I’m not one of those weak people that was always a target for the bullies. If I can explain it clearly, I am part of the peanut gallery. 

Here in the classroom, there are those main characters such as the Class Couple, the Top 1, the Class President, the Class Idol, the Class Hunk and so on and so forth. Every day will be filled with events surrounding them. I may or may not be implicated by it but I don’t mind. I never really had a desire to stand out. It’s fine to be the Classmate A. Being Classmate A helped me a lot to avoid unnecessary troubles. 

But despite being the Classmate A, I have a secret desire that no one knew. Since I was a kid, I have this indescribable urge to steal. Well not to steal things, but to steal someone from another. Not that I keep someone I stole for long though, much less is it known by the person I stole from so before that happens I usually give them back once I grew bored. 

If I remember correctly, it started back in the 5th grade. I saw the Class Hunk of that year confess to someone. The girl isn’t even that beautiful and I still haven’t grown in that department yet, still hairless. But still, I felt an annoying itch inside me to go and steal the girl from him. He might have been the most handsome in class but that did not faze me. It only took me a week to get the girl to fall for me and right after that, I stole her first kiss. And err she also stole my first kiss back then but that’s not the point. Anyway, I did all of that without him knowing and without them breaking up during it. 

Then days passed and the kisses levelled up to more. But since there’s a lack of sex education at that time, we never get passed kissing and touching. I sucked her tongue regularly though. Especially during mornings, I often pull her out of anyone’s sight. The excitement of that grew into me but well, I soon grew bored and let her go. But even though I stopped seeking opportunities to get her, it was she who started longing for me. Not that I mind. We continued that relationship until we graduated, without anyone knowing but us. And during that time, I didn’t stop at one. I also got the most popular girl in school and the smartest girl. Thinking about it now really filled me in nostalgia. 

When I entered Middle School, I continued doing the same thing, stealing someone’s girl, and finally popped my cherry during my 2nd year. It was with a popular upperclassman. It took me a month to get her because her boyfriend had a tight leash on her. I took my chances when he’s not around her. I even tried to ingratiate myself under him to get closer. It worked out anyway so it was worth it. 

Continuing the life of Classmate A, only the girls I got knew the true me. I stopped going to average beauties, but well, since extremely beautiful girls were scarce and harder to steal. More importantly, most beautiful and cute girls don’t have a boyfriend or they were keeping it a secret. I never set my eyes on single girls, I only enjoy the thought of stealing someone’s girl. The excitement I get from it surpasses falling in love with someone. I spent my middle school enjoying lots of girls and most of them were virgins which is a delight. 

Maybe I’m just scared to fall in love and have someone do the same thing I did to me. I can’t let someone do that to me. That’s why I keep being the ordinary classmate. Now that I’m in high school, it’s time to start again. 

I looked around the classroom. The class hadn’t started yet but most of the students are already inside. 

Groups were already starting to form and those who stand out with their roles, I’ve already noted. 

For example, there’s that girl with braids and glasses who sat at the middle of the front row. From what I heard, her name should be Kanzaki Mio. A Class President type. 

Her height is about average but one thing that stands out is her chest, it’s big. If I can guess it’s a D cup. Most boys in class were already ogling her since earlier. 

Kanzaki was sitting seriously there while looking around, checking the faces of her classmates. If ever she has someone, it will really be a challenge for me to steal her. 

Not that I didn’t have experience with her type. Just that, there’s still a slight difference in attitude between a high schooler and a middle schooler so I will have to put in more effort if I become set on stealing her if she has a boyfriend. 

Along with the ringing of the school bell, the door of the classroom opened. 

Entering it should be our Class Advisor for this year. 

Step. Step. Step. 

After the sounds of the teacher’s footsteps ended, all our attention was already on her. 

Upon seeing her, our teacher turned out to be another beauty. A candy for the boys’ eyes and that included me. 

However, her beauty was not the only thing I’ve noticed. 

On her right ring finger, there’s the thing you can only see to someone married. A wedding ring. 

I couldn’t help but smile looking at it. I never tried stealing a teacher back in middle school since there’s no one as beautiful as her there plus my taste hasn’t expanded to teachers yet. 

From how you she looks, she’s probably a newly graduated teacher and our class must be her first advisory class. 


After putting down the books she held on her table, the chattering died down and the whole class fell silent. 

She then leaned on her table and took a glance at each of us. After a moment, she turned around and wrote something on the board. Her name. 

“Miyazaki Shiori. I’m your advisor for the year. Bear with me, alright? This is my first advisory class so I hope you take care of me and I’ll do the same thing to you for the rest of the school year.” Miss Miyazaki started her introduction. 

So my guess is right, huh? 

“So, for a start. You can ask me anything.” 

Upon hearing that. A lot of boys raised their hands and there were some girls who did, they were also curious about this teacher. 

This is a common occurrence every start of the year and each time I only need to watch since what I wanted to know will be asked by someone anyway. 

Ms. Miyazaki looked down at the paper on her table. That was the copy of the list of our names and our sitting arrangements. 

“Okay. You first Yamada.” 

“Teacher, how old are you?” asked Yamada, who was then followed by a laugh by those around him. 

Ms Miyazaki was taken aback at his question but she immediately recovered from it. 

“You do know it’s rude to ask for a girl’s age. Don’t you Yamada?” 

More laughter followed when they saw the teacher’s response. 

After that, more silly questions followed. As if they’re trying to make it fair, there were serious and joke questions asked to her. Unlike the first question, Miss Miyazaki never lost composure again and she answered them all of it calmly. 

I see. Looks like she had a good education as a teacher. But is that all? 

After a rollcall of our names, the Class President was chosen and who was chosen didn’t come to me as a surprise, it was Kanzaki. 


The first period ended that way and instead of starting the 2nd period, it was skipped and we got an hour of break. This was a way to let us be acquainted with each other. The time from before class wasn’t enough after all. 

Since everyone is a new face for me. There were a few who came and talked to me. As the Classmate A, I never turned anyone down and made friends with them. We even exchanged numbers and I was added to a group chat which consisted of everyone in the class. 

Time passed and the first day of the class ended like that. 

I’m just an observer to everyone and since I got acquainted with them, those near my seat often talked to me which I responded to get a fairly good first impression. I don’t need to stand out anyway, as long as I look normal then that’s enough. 

Some of the boy’s group invited me to go home but I rejected, saying I wanted to stay for a little longer. 

It’s not that I have something to do, I just wanted to explore the school. Since this is a new school for me, I need to explore it to find places I might need in the future. Like a hidden spot which I can use when I find a target. I also need to familiarize myself with each and every room like the infirmary, the rooftop, the Principal’s Office and the library. Who knows, I might need to use them as well. 

Walking around the school after class hours gave me some sort of peace as well. I always did this even back then. I could see those who purposefully stayed back, those sports-oriented students and so on and so forth. 

The school was quite big so I guessed it would take me an hour to fully explore it. 

However, when I arrived at the 3rd years’ floor, a surprising scene appeared before me. 

In one of the classrooms, I found a very interesting sight. And yeah. It involves my secret desire. 

“N-no, someone might see us here.” 

A girl’s voice rang in my ears. It came from an upperclassman inside the room. Though it’s soft, I can hear it clearly because of the silent corridor. 

I peek at the door to see inside. There are two people in there. The girl who I heard and another one. I don’t need to guess who it is, he must be her boyfriend. To think that they have the nerve and the courage to do it on the first day of the school year. I’m seriously amazed that I even wanted to give them a clap. 

Both of them almost had all their clothes on the ground. Te girl sitting above a desk. Her skirt was pulled up and her undergarment was pulled down to her legs. 

Because her top uniform was unbuttoned, her twin peaks were in full view and due to the sunlight coming in from outside the window, they were glistening beautifully. 

I immediately pulled up my phone and took photos of that scene. Also I made sure to get both of their faces clearly. 

The guy was currently working on his belt to pull out what’s hidden behind his pants. 

But, of course. Who am I? Seeing this sight invoked my secret desire. 

On the first day of school year, I found my first target.
