Hey hey hey people. I realized that there aren't a lot of ATG stories on FanFiction and decided to grace you with mine (kidding). It's my first fanfiction ever, so I'd appreciate helpful criticism. This is my take on the an ATG reincarnation story. I'll try to make it slice of life/adventure/romance. Harem = 3 and each woman will have their own story and relationship with the mc.


Synopsis: A young assassin suddenly dies and is reincarnated in the ATG world.

Giving an opportunity to start anew, will our protagonist stay alone and grow strong to the point of being feared by the heavens or will he finally find the family he always longed for.

Join the journey of Yami, where he will fall in love, conquer mythological beasts and fight against entire realms while at the same time discovering mysteries unexplored in the novel.


I don't own ATG nor the other works mentioned.

I also published this story on webnovel under the same title.

With that said and done let's get right into it.


A few miles near Floating Cloud City a young child laying on the ground in the middle of the night stirred.

Short black/grey hair flowing in the wind, golden slitted eyes looked around with a cold, calculating gaze 'Where am I?'

Despite the dark, the young child could perfectly look around and analyze his surroundings.

He was on a road in the middle of what looked like a forest. Only that the road was natural and the air was fresh.

'Where am I?' His vision started to blur, he felt weak, extremely weak. The young child tried to stand up but couldn't. His mind was muddled and he couldn't think straight so he decided that he'd at least get to safety.

He crawled his way out of the road. After a few minutes of struggle, he rested his tired body against the trunk of a tree panting heavily. He grabbed a stone nearby and held it tighter as he tried to clear his mind and think of how he got here.

He raised his hand and raised an eyebrow when he saw that it was fair and small, unlike his big and rough one due to extensive training.

"Right, I reincarnated" he murmured. He felt the ground tremor and sensed a few presences coming his way.

The boy tried to look at the incoming people. But his vision blurred once again. The only thing he saw before he passed out was four weird horse like creatures pulling a carriage


'As an orphan trained since birth to become an assassin, and being a genius on top of that, my life was hmmm … dull, meaningless.

I mean, as soon as I could remember I was taught what is the best method to kill someone. My life consisted mostly of me killing people for money after I escaped that hellhole where I was raised.

I don't have a name, they never thought it to be useful to give me one when I was young. They just called me 23. I never got myself a name ever since. Sure sometimes I used aliases like John or Frank if I needed it, but I didn't see the use of having one when I didn't have relatives or friends.

I tried being a normal person and settle down. But years of fighting and assassinations made me restless in a peaceful environment. Call it an itch that I couldn't get rid of if I didn't move around. It's not like I was craving for blood, it was more like I couldn't bear to work behind a desk for X hours a day. I tried dangerous sports, but even that didn't help.

Going back to true and trusted methods of hunting cash cows (organized criminals) made things easier for my wallet and calmed me down.

Despite all the actions I had, I didn't really enjoy my life. To me, all I did was basically survive in this world, earning money through killing. My only moment of freedom was when I watched anime or read mangas where I could basically leave this word where I have no ties.

Not that it matters anyway because I'm dead. I'm currently in a black space. I don't mind though, it's peaceful. And I've always liked the color black and dark spaces, maybe because of my occupation.

I don't remember how I died, maybe one of my clients wanted to get rid of me for whatever reason, maybe I just had a heart attack in my sleep or maybe some god threw lightning that magically targeted only me or sent a newbie truck-kun who mistook me for someone else and I'll get reincarnated with some wishes like in those fanfics that I loved to waste my time one'

Suddenly a screen pops up in front of the soul in human form, causing it to raise an eyebrow 'Huh, look at that, you think about it and low and behold~'

[If you could reincarnate in the fictional world Against The Gods, would you take that chance Y/N?]

"Yes''

'I love the prospect of having unlimited strength and lifespan. And it's a world where the strong have every right. I think that with my experience as an assassin and my intellect, I could probably finally live a life freely and enjoy myself. Sure it'd be better if I could have a wish but I don't know if the thing in front me will give me one, IF it really does send me to that world. I wouldn't mind going for a world like Shokugeki no Soma and live a peaceful life but I don't know what happens if I say NO. But a cultivation world is fine as well, I always wanted to try out those super inhuman moves I watched in anime or read about.'

[What type of profound veins would you like? (if none of the known ones interest you, you can customize one. Be as specific as possible)]

'Hmm I've been an assassin for my whole life, so I don't think another type of fighting style would fit me, plus I was a genius at it. So I need something which prioritizes concealment, something that allows me to strike from the shadows without being noticed … Shadows!'

"Devouring Darkness Profound Veins: Gives me control over the shadows and darkness energy. I can also devour others with my shadow and absorb their profound energy. My profound veins will automatically compress that profound energy and refine it to be at its most purified form for my cultivation."

"Also I want to be able to revive dead people or beasts as shadow soldiers who will never die as long as I have enough profound energy and who will grow stronger the more shadow they absorb"

'I never liked how cultivators spend most of their time in close cultivation when they could simply enjoy that beautiful world. I want to enjoy my second life if all of this is real so might as well be as strong as possible. Sure, at some point I will get to a point where no matter how much I devour I wouldn't grow in strength and I will have difficulties reaching the higher realms but I'll think about it then. Everything is possible in that world after all.'

[You shall only be able to revive beasts as shadow soldiers, do you accept Y/N?]

"Yes, *phew*…" The soul sighed in relief 'I thought that this was too much at first but who'd have thought that it would just nerf me a bit'

[Choose a system]

I don't want a system which will basically control my life when I have finally the opportunity to be free, so I'm not going for something I read before. I'll just customize one.

"I want a system which gives me access to all cultivation techniques of the ATG universe. I also want to be able to create better cultivation arts by merging existing ones."

[Choose 1 power]

'Nice, I guess it passed. Hmm, as for a power ... I'm already pretty strong, and the different cultivation techniques in my system will be more than enough for me to get strong really fast'

"The ability to make what I imagine come true"

[Granted, but this power is deemed too powerful and thus will be weakened]

'I don't mind, I never intended to use it for fights in the first place but for my comfort. The ability to create anything will be extremely useful for my comfort in a world with a medieval setting. I don't know how they go to the toilet there and I hope I never have to. I'll also be able to recreate manga and anime there with my eidetic memory.

[Describe your new appearance (you can still keep your current appearance)]

"Make me look handsome, with black/grey short hair and golden eyes with vertical slits. Let my final height be 190cm and have a pretty decent dick size. If I ever have sex, I don't want to ruin the girl I have sex with with those arm length dicks in the fanfictions I read."

[In what circumstances would you like to reincarnate?]

'I don't want to have a biological family since my enemies could go after them, and to be honest, even if I'm mentally 24 I'm afraid of having a family isn't up to my expectations.

I want to have the time to train and refine my skills so I should reincarnate at around 7.

I need to reincarnate in a safe place where I can grow peacefully. So no God Realm where a fly can sneeze and kill me. It also should be around the timeline as it's safer for me that way. If I'm strong enough before canon then I can just not give a shit.

I also want to interact with Xia Qingyue. I really pity her fate, blinded by the desire to meet her mother to the extent of neglecting her own family just because her mother's departure caused her a mental blow and at a young age (A/N: 4 years old)'

"I want to be saved by Xia Hongyi 1 year after his wife disappears and brought back to the Xia manor as a 7 year old (2 years older than Qingyue)."

[What will be your name in your new life?]

….

'I guess since it's a new life I could at least choose a name for myself. Let's go with this then, I really like this character in Black Clover, plus it's related to my profound veins so I guess it's a fitting name'

"Yami"


On the road to Floating Cloud City, a carriage can be seen surrounded by a dozen bodyguards all on alert ready to protect the person inside.

Xia Hongyi, leader of the most prosperous clan in Floating Cloud City was on his way back from a business transaction in Cyan Forest Town.

In reality he didn't have to go himself considering the distance of 200 km from his home and the minimum importance of the deal. But ever since his wife, Dongxue, recovered her memory one year ago and left to the "The Realm of the Gods" according to her parting words, he couldn't stay at home anymore since everything there reminded him of her.

After finding her injured and saving her from the snow 7 years ago, she woke up extremely weak and with no memories of her past self. He tried to personally help her recover, but despite all the medicines bought and doctors who visited they couldn't find the reason for her illness. They spent the next 2 years together and eventually fell in love with each other and had 2 children, Xia Qingyue the eldest and Xia Yuanba. But 3 years after Yuanba's birth she recovered her memories and power. She then hurriedly left saying that her aura probably attracted her enemies and she would cause a calamity to everyone close to her.

Since then, he hardly stayed at home and decided to busy himself with work to not think about her.

He knows that his eldest daughter wants to reunite with her mother and so does he, but even he doesn't know of this place called the "Realm of the Gods" despite all his research.

Therefore, he can only shake his head thinking of the still depressing Xia Qingyue at home, probably in her mother's room again ... alone.

"Clan leader, we found this child outside. What do you want us to do with him?"

Xia Hongyi's train of thought was interrupted when the captain of the guards suddenly entered his carriage with an unconscious child, maybe 2 years older than his daughter, with a cute face and grey/black short hair.

"Let him rest in the carriage. Speed up the pace immediately and order someone to go at full speed to inform Doctor Situ from the Xiao clan, he needs to see a doctor and see if he is fine!"

Xia Hongyi quickly ordered as he carried the boy personally and covered him in a blanket that suddenly appeared in his hands.

"Yes sir!" the guard responded back before going out of the carriage, not all surprised by the fact that one of the most influential men in Floating Cloud City would care about an unknown boy in this cruel world. After all Xia Hongyi was known for his kindness.

Xia Hongyi looked at the unconscious boy deep in thought before eventually sighing when thinking back to his family that is currently breaking into pieces


Yami woke up in an ancient Chinese styled room. Looking around in confusion, it took him quite a while for realization to hit him.

He tried to feel some kind of energy, like every main character did in the fanfictions he read, by closing his eyes and trying to 'sense' the profound energy in the air. To his surprise and great joy he could!

'So it really wasn't a dream~'

He then tried to absorb the profound energy in the air and lead it towards his profound veins which he could feel above his navel but as soon as the energy came in contact with his profound veins it left his body.

'Hmm I guess that's the price to pay for having the devouring profound vein, I can only devour others' cultivation to increase mine. Not like I'm complaining, I never intended to sit around all day cultivating, that's way too boring. Though it might be troublesome in the latter stages of cultivation when stronger cultivators get rarer, but I will just think about something then. But for now ...' He thought as he looked at the door

A few seconds later, the door opened and a middle aged man came in. surprised that the young boy had already woken up. Now that he's awake Xia Hongyi noticed that his eyes were golden with black slits in the middle making him look like a beast.

Despite his surprise, he still regained his composure and spoke gently trying to not to scare the young boy

"Hello child. My name is Xia Hongyi, I was on my way back to Floating Cloud City when my guard found you collapsed on the roadside. Do you remember anything"

Yami pretended to be ignorant and spoke calmly

"I .. all I remember is my name … Yami. Have you found anything else beside me that could point out where I come from?"

Xia Hongyi was surprised at first that the child indeed didn't remember anything. 'Just like her' he thought, saddened that a child couldn't remember his past. .

But he was amazed at how he was taking it so calmly when most of the children would start panicking and crying

"No we didn't find anything. Maybe your memories will come back to you in the next few days. You can stay in our house until then"

Yami stayed silent for a second before thanking him genuinely since even though it probably wasn't much to the clan head, it was the first time someone cared for his well being

"I'll have to accept your offer then. Thank you very much and I'll definitely repay you if I can in the future"

Xia Hongyi just smiled and proceed to leave before saying

"Oh right, I have a daughter and a son, they are both younger than you but not by much. If you find yourself having nothing to do, you can go play around with them"

After Xia Hongyi left, Yami used his system and fused all the cultivation techniques related to concealment, shadows and darkness available to create the "Devouring Darkness Profound Art" which will allow him to have better control over shadows and easily master a new ability every time he breaks through a great realm:

Elementary Profound Realm: Devour enemy's profound energy and can revive beasts as shadow soldiers

Nascent Profound Realm: Manipulate the shadows in any sharp shape (Spikes, scythes, blades)

True Profound Realm: Hide in the shadows and become invisible and intangible

Spirit Profound Realm: Can move while in the shadows

Earth Profound Realm: Can mark someone's shadow and can teleport to it (works only on living beings)

Sky Profound Realm: Can use power of Darkness to coat user's body, doubling his physical power. Can also control the darkness profound energy in different forms like wings to fly faster, or an arm to increase range of attacks.

Emperor Profound Realm: Surrounds the user with a black spherical domain that immobilizes every enemy at a lower cultivation rank and slows down enemy at same or higher rank. Only the user is allowed to fly in this domain

Tyrant Profound Realm: Can take control of someone's body as long as their cultivation isn't 2 realms above user's

Sovereign Profound Realm: ? Needs a powerful darkness treasure to activate

Even though he expected this, Yami couldn't help but be dumbfounded. He knew that even with his genius talent and intellect it would've taken him months to learn how to control his darkness energy to recreate these abilities, especially things like hiding in the shadow or reviving beasts, since it was his first experience with cultivation after all. But thanks to this profound cultivation art he only has to kill to grow strong.

Yami let out a small smile filled with conviction 'This time, I'm going to live my life freely. I don't know why most main characters in fanfictions decide to rule the world. I'm just going to let Yun Che or someone else do that. I don't need Asgard, I don't need the Blue Wind Empire, I just want to relax in this new life. I don't have a goal as of now per se. But I'm still young, I'll think about it in the future'

Yami let out a yawn and decided to sleep. Even though he wasn't tired physically but the mental exhaustion was too much for a 7 year old body.


The next morning, Yami woke up feeling a weight on his chest. He then heard a childish voice: "Wow elder sister look it's real! He really has super cool eyes"

Looking at the young boy on Yami said with a strained smile since he was kind of suffocating with the young child sitting on his chest "Hey, you must be Xia Yuanba"

"Yuanba don't sit on top of him, you're bothering our guest"

A second voice interrupted the little guy who was about to answer,

Yuanba looked at Yami and smiled sheepishly before getting off

"Sorry about that big brother, it's just that father told me when I woke up that he brought home a big brother with cool colorful hair and golden eyes like that of a dragon so I wanted to meet you".

Yami smiled gently at the young innocent boy and petted him "Don't worry about it, I don't mind"

He then looked at the young girl standing a few meters from his bed. Crystal blue eyes, long shiny black hair, thin lips and a beautiful face that would put most models back on Earth to shame despite her young age 'I never had any interest in girls before but even gay people would be attracted to her when she grows up if she's already this cute at this age!'

"And you must be Xia Qingyue, nice to meet you, I don't know how long I'll be here but I hope we can be friends." He said gently after recovering from his short daze

Xia Qingyue looked at him silently for a long time and seemed to struggle before she turned around and left.

'Hmm? Did I do something wrong?' He thought and looked at Yuanba questionably.

"Big sister has been really sad ever since mom left us, she usually doesn't leave mom's room but she was also curious about you. Don't worry, maybe one day we'll be able to play together!" Yuanba said sadly

Yami stayed silent for a while before trying to change the subject

"Hey Yuanba do you want to play around the city? I don't remember anything so I'd like to discover many different places"

The little boy immediately started to jump around in happiness before he left the room shouting "I'll tell father immediately !"

'He probably was bored staying always cooped up at home with his sister in depression and his father always missing.

If I remember correctly, he often went out outside and got bullied because of his timid nature and his big body. He's still a kid so the Tyrant Profound Veins didn't affect his body yet. I could probably influence him to change his temperament a bit in the future. After all, in the novel Yun Che would look after him every time and always defended him, never letting Yuanba solve his own problems and mature, always being ignorant, that's why it took so long for him to awaken his Tyrant Profound veins' Yami chuckled before he stood up from his bed and got ready for his first day in a new world and hopefully, his new life.

Additional scene that I could add:

He laid on his bed and looked at the ceiling deep in thought.

He had reincarnated, meaning a clean slate, an opportunity to start over from the start. Live a childhood. He noticed that his body's age altered his personality somewhat and he could act like a kid naturally which he quite enjoyed since he always desired a childhood. He closed his eyes

'Even if I want to get stronger, I still want to enjoy my life. And if I worry too much then I'll never stop getting stronger considering that there is always someone stronger out there. I don't even know if there aren't Divine level beasts or people out there, after all, the story only covered one part of the planet. I'll try to enjoy my childhood here for now'

Yami opened his eyes and smiled as he felt happy, happy that he could start over, happy that he could enjoy what he always longed for. He stood up and got ready for his first day of his new life.


NEXT CHAPTER: (2) Freedom


A/N: Important info for the rest of the story

The main character will be strong, OP, borderline Godlike, but that's just when compared to other cultivators in canon. He will often fight against stronger enemies during his adventures. But he will still flex on others a lot.

This will be a small harem (3) and I will take my time with each of them to delve deeper in their character and their relationship with the main character, Yami. Xia Qingyue may or may be not included depending on how the story goes.

While the main character might be present for some events of canon, he will be mostly focused on his own adventures.

I will use elements of japanese like "onii-chan" or "ara, ara" or will refer to some mangas, and anime sometimes. The characters won't just use them like that out of nowhere. Yami will introduce them to it (using his imagination magic to create mangas, the entertainment in that world is practically non-existent so he will create mangas). If you don't like it, then don't read or just ignore those moments

With that said, enjoy
