A modern bankrupt manager who was driven crazy by KPI accidentally transformed into a down-and-out nobleman of the Tang Dynasty. He wanted to use modern knowledge to get rich in a low-key manner, but he was nicknamed the "bankrupt man" because he destroyed half of the luxury stores in Chang'an City. This even made the "No. 1 Merchant Woman in Chang'an" hate and be curious about him, and thus began a love story in the prosperous Tang Dynasty.
