The time traveler Chen Hao found himself in a different world where cards were supreme. At the beginning, there was only one of the trashiest "Slime" cards. He used the knowledge from his previous life (game experience, common sense of physics and chemistry, etc.) To perform "saucy operations" and developed unique decks and tactics. He rose from the bottom to explore the truth behind the drastic changes in the world and fight against the powerful card empire and the mysterious "Card Destroyer".
