In the ancient Mysterious Vein Continent, the commercial system centered on Mysterious Vein resources (mysterious stones, mysterious grasses, and earth veins) was trapped in the contradiction between the monopoly of the old nobles and the rise of new merchants. The protagonist Lin Zhao, as a handyman disciple of the Xuanmai Sect, is determined to expose the truth through business war because his parents were framed and killed by the old nobles. He started by resolving a minor conflict among the sect's handymen, and used his clever strategies to get involved in the fight for Xuanmai resources and the layout of the caravan. He resolved misunderstandings with the eccentric childhood sweetheart Su Xiaotang, and successively dealt with rivals, charlatans, domestic servants, traitors, greedy landlords and other villains. In the wave of the reform era, he promoted the liberalization of Xuanmai trade, integrated all forces, expanded territories, and eventually became the world's merchant master, realizing justice and ideals.
