Lin Ruo, a modern top sales champion, unexpectedly travels back to ancient times and is sold by her own grandmother to be buried in a ghost marriage right from the start. She fakes her death in a coffin and escapes, taking her family away from their terrible relatives. Using her modern business acumen, she makes sugar, produces military rations, and opens shops, gradually turning a small sugar shop into a commercial empire in the Great Qian dynasty. Along the way, she tears apart a scumbag, humiliates local bullies, turns the tables on business spies, and unexpectedly gets caught up in a struggle for royal power. Prince Jing, Xiao Jingzhan, who is secretly traveling incognito, is originally just her customer, but eventually becomes her strongest backer and pursuer.
