One Piece: Fist of the World - Chapter 15: The Sword Pointed at Speda Myers

Vahn was an atypical youth. Due to a rare mutation, his blood had the potential to target and attack ailments within the human body. Touted as a universal cure, people had elevated his status above the norm and given him the classification "Panacea". In the media, he was hailed as a great hero who would usher in a new era or human wellness. However, behind the scenes things weren't so bright. Being a unique individual, Vahn spent his entire youth locked up in a lab with various scientists and research teams using his body and blood to perform endless amounts of experiments. The only solace in his suffering was the various anime and manga made available to him between experiments. He often imagined himself as the protagonist in a world of his own, finally in control of his own destiny. For years he nurtured this desire, until at the age of 14 he died when an organization had tried to kidnap him from the lab...

He died on Earth with nothing—no legacy, no power, and no second chances... or so he thought.After getting hit by a truck, a disillusioned young man awakens in the body of a boy named Zane, in a war-torn fantasy world where nations clash over power, and magic is the law of survival. Gifted a mysterious book from parents he barely knew—and now lost forever—Zane accidentally awakens the Void System, a cold, cryptic force that offers power... at a price.In a world of monsters, systems, and bloodshed, Zane doesn’t get a choice.Survive, or vanish into nothing

He returned with a vigorous presence, equipped with a Heaven-reaching Innate Ability. He could heal, tell fortunes, refine medicines, set formations, and refine talismans… “There’s nothing in this world that I can’t do!” — Shen Feng.

Lucien was chosen by the God of Gamblers to participate in the Heaven’s Gate Project. Their goal was to help save a dying world from destruction, and ensure that it wouldn’t be destroyed a second time.

Unfortunately, things didn’t go according to the God's plan. Lucien’s soul was heavily injured during the soul transfer and on the verge of collapse. Having no other alternative, the God of Gamblers was forced to take yet another gamble to preserve his chosen candidate’s soul and help him find a new vessel.

As if arranged by Fate itself, Lucien’s soul wandered into the world of Solais until it merged with the dead body of a newborn baby that was left to float down a river. With his new identity as Lux, the boy realized that even with the blessings given to him by the Gods, saving a world was not an easy matter.

In a world of Swords and Magic, where adventures run wild and free… the Legendary Saga of an abandoned Prince is about to begin!
