[Card-based powers + play the pig to eat the tiger + slow burn in the early chapters] Chu Yuanxin joins an agency, and his very first assignment is to divide up the Old Chu family inheritance on behalf of his father. In the end, he receives a mysterious deck of playing cards, setting him on the path to becoming a powerhouse.
A word from the author:
[Card-based powers] means that supernatural abilities are mainly expressed through cards, which are also used in combat. The pacing is slow at first to avoid a sudden breakdown in the power scaling later on, and to show the process of growth.
[Play the pig to eat the tiger] describes the protagonist's hidden personality. This comes mainly into play starting in the second installment, which leans toward wish fulfillment.
[Slow burn] means that the first installment moves very slowly. In the overall structure, it serves as a prologue or prequel. Readers who dislike a slow pace can start with the second installment.
