One Piece: God of Space - Chapter 23 Invitation

Within the Huang Realm, a world where the era of divinities has ended and the era of immortals is nearing its waning years, exists the Buzhou Immortal Sect. And within the Buzhou Immortal Sect on Jade Peak was a disciple of the sect, Xi Tianyi. He was of noble birth, the only child of the Sword Empress who reigned invincible.

But the truth was that Xi Tianyi, was originally an ordinary mortal from Earth who suddenly woke up one day as in another world filled with immortals and demons. Under heavy pressure, knowing that his life is at stake to whoever is strongest, Xi Tianyi quietly cultivates in hopes of one day fearing no one and discovering the circumstances of his transmigration. But…

«You bastard, you stole my fiance!» Said a former genius who had lost all his cultivation.

«Bastard, pay with your life for the death of my entire clan!» Said a cultivator with blood leaking from his hatred filled eyes.

«What the hell?! I’ve been cooped up cultivating quietly so why are you guys suddenly finding trouble with me?! Besides, I’m only ten!» Cried out Tianyi in disbelief.

«Fine, if you want to make me your cannon fodder, I’ll step on your corpses for my ascension!»

“What those edited and conceptualized main characters call ultimate and full power is but a grain of sand under the steps of my weakest subordinates.” Quote from Patrick.

Patrick, a regular arrogant kid with extremely attractive looks and a high IQ, lived in the alternate version of Earth. But in this alternate Earth, there were awakened humans who possessed abilities beyond the scope of human knowledge. Yet, despite living in an awakened world, Patrick didn't awaken any ability.

But just when he was annoyed with his unawakened life, he acquired an unknown entity called a system. With that, it opened a gateway of infinite possibilities that caused the existence of the story “GOD OF ALL SYSTEMS.”
