[Jiangshi] [Multiple heroines] [Black Dragon] [Doesn't join the crew] After transmigrating into the world of One Piece, he gets the golden finger of corpse-refining arts! Gion: “What should I do? This man is simply too strong.” Sengoku: “If only he had joined the Marines back then. Sigh...” Kaido: “What is this monster? It has an indestructible body just like mine!” Garp: “I've never seen a monster this powerful. Its strength is terrifying!” Charlotte Linlin: “Wonderful, a new species! Katakuri, go find him and tell him that if he agrees to join us, I'll marry Smoothie off to him.” Dracule Mihawk: “I can already see a new era, the new era you bet on, Shanks. It seems it's destined to fail.”
