Naruto System in One Piece - Chapter 379: The Luffy Pirates (1)

In a future timeline, the earth was visited by a species known as the Slarkovs.
Having lost their home planet and in search of a new one, earth was the next habitable planet for them.

Humans and Slarkovs made a deal with each other in return for the Slarkovs living on earth.
The Slarkovs traded their technology and knowledge for a new home.
They were similar to humans except for some of them who had slight differences so fitting into the society wasn't a problem.
Over the years Slarkovs and humans began to mate with one another and reproduce offsprings.
This in turn created a new species known as the mixed-blood.
Centuries later mixedbloods could tap into their bloodline and perform unimaginable feats.

Gustav born into an age where bloodline determines everything, struggles to fit with a useless bloodline.
His bloodline only grants him the ability to change his hair color, destroying his hopes and dreams for a great future.
His fate is turned around when an unexpected situation leads to him finding a system that grants him the power to unlock and upgrade bloodlines by completing quests but he's baffled by two quests with a five-year deadline. Success will grant him unimaginable rewards...
But only one thing awaits him if he fails... Death!

Follow Gustav on his interesting journey filled with unprecedented adventures, danger and death, maybe?

Octavius, misled by friends, embarks on a quest to clear his father's name, ultimately facing a tragic end with his sister.Their journey results in devastating loss, leaving him powerless and yearning for revenge against those who harmed his family. Spirits offer him a chance to reincarnate, but he refuses, saying;“What’s the point of a new life if I keep running from my problems”The entities are taken aback by his unwavering decision, having never encountered a spirit who refuses to escape their troubled past. They warn him about the evil being that now resides in his old body, but that only motivates him. He believed In the saying - to defeat a monster, you have to be twice as monstrous.Embracing his fate as The Phantom's Gambit, they traverse the shadowy path of retribution, their identities blur, secrets unravel, and the line between savior and monster fades.This is a tale of darkness and redemption, where justice is a blade, and revenge is the only way forward.

This is a story of the flesh pushing everything.

In the Great Ye Dynasty, darkness descends, full of evil spirits and ghosts, killing invisible.

In the face of demons and evils, ordinary people can only shiver, curl up in the corner, and wait for their lives to come to an end.

Jiang Dao came through, carrying a martial arts modification system, and any martial arts can be modified infinitely as long as he glances at it.

The mad magic stick method, the eagle claw iron cloth shirt, the poisonous sand palm, the violent ape magic… are all revised to the realm of a thousand years later.

Facing the evil spirits, Jiang Dao had a burly body, muscles all over his body, and his eyes were like electricity.

“Evil spirits? Who said martial arts can’t kill evil spirits?”

- Description from novelbuddy

Fuck me.I was just trying to pull my favorite character from a gacha game — Trafalgar du Morgain. The legendary swordsman. The cursed heir. The tragic side story no one cared to fix.Discarded by his clan. Humiliated by his siblings. Dead by suicide before the main plot even began.Guess who woke up in his body?Yeah. Me.Now I’m stuck in a game world that had zero lore, zero guidance, and zero chance of survival — except for the broken-ass Talent I somehow unlocked.I’ll kill, steal, lie, betray—whatever it takes.If survival means blood on my hands, then so be it.I didn’t choose this world, but I’m not going to let it chew me up and spit me out.I’ll climb over corpses if I have to. I’ll become the villain, the monster, the nightmare they never saw coming.Because in this world, there’s only one rule that matters: survive or die.And I’m not dying again.~~~More tags: no Yuri, no NTR, transmigration, rarebloodline, no dense mc, dragons, dragon girl, dog girl, vampire, succubus, mana cultivation, cursed heir, academy setting, secret identity, hidden talent, demons, death and rebirth, political intrigue, ancient bloodline, dark fantasy, family conflict.
