I Transmigrated to Another World, and My Cheat Is the Myriad Worlds Potion System

Lu Chen was struck by an unbelievable stroke of luck and sent to another world. When he woke up, he found himself in a cramped ship's cabin. No matter how loudly he shouted, no one answered. Then he discovered he had acquired a golden finger called the Myriad Worlds Potion System.

Ding! Host detected in the One Piece world. Newcomer activity gift pack: one Sailor Path potion, one super soldier serum, two doses of Remy's aid, and five lower-grade life potions.

After escaping the cabin, he discovered he was in the world of One Piece.

The potions could actually let him transmigrate through time and space, and so Lu Chen's travels across the myriad worlds began.
