One Piece: the Rise of the Dark Emperor: Blood-Stained Scepter

After traveling through time and becoming a low-level thug of the West Sea Mafia, Carl was almost sunk in the sea at the beginning. Using modern knowledge to create black powder, he blew up rival families and rose to power. Smuggling arms, selling intelligence, operating casinos... Seven black industry chains took shape in his hands. When Luffy shouted "I want to become the Pirate King" in Rogue Town, Carl was using blood-stained money to bribe the top brass of the Navy. Two years later, they reunited in Shampoo. Zoro's sword could not cut through his dark golden thread, and Sanji's kick could not destroy his underground kingdom. Until the decisive battle in Wano, he supplied Kaido and Orochi's weapons. "Straw Hat, your sunshine cannot shine into my abyss." Karl sat on the fake throne of the void and smiled, "I am the shadow king of the new world." This novel and its characters are purely fictitious.
