The soul of modern financial elite Chen Huai traveled back to the Qianlong period and became a down-and-out salt merchant on the verge of bankruptcy in Yangzhou City. Facing the deadlock of corruption in the salt administration, collusion between corrupt officials, and the presence of salt lords, he relied on his advanced business methods and his ability to see into people's hearts, starting from an empty IOU to leverage the salt industry. Joining forces with Su Wantang, the orphan of the salt merchant, Chen Huaian investigates hidden accounts, fights against the Cao Gang, breaks the salt and leads to the black market, and gradually forces the corrupt official Zhao Bingzhong into a desperate situation. But behind the salt tax, the game between the court factions and the imperial power was involved. When the Forbidden City also set its sights on Yangzhou, he had to make a choice between becoming rich and invincible, or dying and annihilating his family.
