Three thousand years ago, Xu Yuan came and aliens invaded. Humanity rebuilt civilization on the ruins and built everything on cards.
Su Ye, an otaku who died suddenly, traveled to the card world after being seduced by the underworld, and became a student in the elite class of the card-making department of Cangqiong Academy. The original owner was ridiculed as a "parallel import genius" - he was top-notch in repairing cards, but he couldn't produce an original card.
But Su Ye came with the underworld card and proficiency system! Not only can he make Pokémon cards such as Pikachu and Eevee, he also created a revolutionary evolution card system that allows low-level cards to evolve into high-level combat power and even fight across levels!
But this is just the beginning...
When everyone thought he was a parallel importer, Su Ye used original cards to slap everyone in the face.
