In One Piece, I Can Sacrifice Anything

Reborn in the world of pirates, with the Myriad Worlds Sacrificial Altar in hand.

A broken sword can be sacrificed to obtain a Fine Blade. A swordsmanship notebook can be sacrificed to gain Shimotsuki Ryuma’s lifelong mastery of swordsmanship. So what would I get for sacrificing a tyrannosaurus?

Li Feiyu looks at the Master, who has appeared before him, and quietly takes the Dragon Talisman from him.

Only after he stands at the center of the world and sacrifices all of Mary Geoise before everyone’s eyes do people realize that everything has only just begun!

Sengoku: Li Feiyu isn’t just a world-class criminal. He’s the most dangerous person alive, above both the pirates and the Revolutionary Army.

Garp: What are those eerie shadow soldiers? Why can’t they ever be killed?

Big Mom: That terrifying bastard actually ate all of my Totto Land!

Kaido: I thought I was the only Devil Fruit User in the world who could turn into a dragon, but he can summon ten thousand dragons!

Blackbeard: That damn bastard! I’d only just eaten the Dark-Dark Fruit, and he went and created hundreds of Dark-Dark Fruit Users...

P.S. A sacrificial offering story + sword saint. Lots of artifacts appear, and I’ll do my best to identify their origins and the worlds they come from.
