One Piece: Supreme Check-In System - Chapter 65: Oaths of Steel, Bonds of Blood

Reincarnation.A concept everyone is all too familiar with, at least once in our lives, we've all thought of being able to just let go of all our regrets and the things holding us back and just start over.This deal is made even sweeter when paired with being allowed to keep your current memories and knowledge of the future.William was one such boy who had been given this once-in-a-lifetime opportunity.Like any other modern-day person, the first thing he did after learning about his reincarnation was check if he possessed any memory that was similar to his new world.Sadly, in the end, he was left disappointed and was forced to go into his new life completely blind and unaware of all the malicious entities, world-ending threats, and divine schemes going on in the shadow.But then again, who needs knowledge of the future when you are the child of mana itself?

Even after knowing what came next....I still accepted.A deal with the devil herself.A devil, in the form of a goddess.I accepted a life that I knew wouldn't end well, a life that was worse off than the very curel one I already lived.But I still choose to do it.I chose to become the villain.

A long time ago, the decayed main god space collapsed and disintegrated, and the wreckage was scattered in parallel universes, giving birth to a new space…

Countless ‘story worlds’ under control have also fallen into the void, regained freedom, runaway out of control, elevated to reality, and turned into reality.

At the same time, these “worlds” are polluted and corroded by the void, giving birth to greater fear and filth…

…

The space of birth feeds on the world.

They compete with each other, their tentacles penetrate through dimensions, invade different time and space, search for the legacy of the main god, drive the apostles to be minions, greedily tearing, seizing, devouring, and reclaiming one world after another, so that they can return to greatness.

…

The innocent eating melon and white waves with the legacy of the Lord God accidentally got involved in the parallel universe “Paradise of Fire” during a cross-border call.

After forcibly binding the demi-human blood, he became an excellent tool man who can repeatedly die, starting the legendary ‘dimension invasion career’.
