Mok Hwi‑yeong, a great merchant of the Central Plains, is killed in a demonic cult’s attack. The next thing he knows, he has regressed thirty years into the past, back to his childhood days training as an outer-sect disciple of the Wudang sect. Before him appears a mysterious bamboo slip, a “shop” that lets him buy martial talent with money. With a merchant’s brain and a pay‑to‑win system that sells everything from heavenly insight to a Martial King’s physique, the returned Mok Hwi‑yeong begins shaking the entire jianghu from within Wudang.
