Pirates from the King of the Desert to the King of the World

What will the world look like when Crocodile obtains the memory of the time traveler and the royal system? Crocodile can gain a creature's power by gaining its loyalty. Devil Fruit, three-color Haki, physical power, and special abilities will all become his powers. Starting from the desert kingdom of Alabasta, there is the Sky Island located 10,000 meters high in the sky, the Fishman Island located 10,000 meters under the sea, the uninhabited Nine Snake Island, and the Wano Country in the new world. "Surrounded by countless creatures, I, Crocodile, will eventually ascend to the throne of the King of the World!" (Dark Flow) (Struggle for Hegemony) (Cold-Blooded) (Multiple Female Protagonists)
