One Piece: I Became Invincible After Inheriting Roger’s Legacy

After transmigrating into the world of One Piece and becoming a prisoner in Impel Down, Wayne endured a life worse than death. Fortunately, he had the Myriad Worlds Commission System. Completing commissions earned him all kinds of rewards. [Commission: The Pirate King's Last Wish: Help Roger look after Rouge until Ace is safely born.] Reward: 1. Roger's strength (current state); 2. Roger's Conqueror's Haki (peak) [Commission: Rampage at Mary Geoise: Protect the World Government on behalf of Golden Lion Shiki, then attack Mary Geoise.] Reward: Float-Float Fruit (awakened) After inheriting Roger's legacy and Shiki's Float-Float Fruit, Wayne discovered that he had become terrifyingly powerful. He attacked Mary Geoise and became the most evil criminal in history, as the World Government called him! But that was not all: Wayne had several secret identities. He was the founder of the Sweetheart magazine, the host of the World Beauty Pageant, and the man behind every Miss World; He was a Shichibukai, and the arms company he founded single-handedly sparked a global arms race, earning him the nickname King of Arms; He was the head of the Chaos Ladder, an organization that struck terror into the World Government. Bullet, Crocodile, and the Red Count were all his Four Horsemen of the Apocalypse; He was Kaido's business partner and a welcome guest at Big Mom's table; He was... Wayne had many titles, but in the end, people called him the King of the World!
