During the Dajing Dynasty, Qin Song, the treacherous prime minister, was in power. The Shen family, the former loyal general, was framed and executed. Only the orphan Shen Jinci managed to escape. She hid in the market for seven years, transforming into an accountant and secretly collecting evidence of crimes, just to avenge the Zhaoxue family.
In an accident, she met Xiao Fuyun, the seventh prince who seemed to be carefree and unruly, but actually had a lot of troubles in his chest. Xiao Fuyun saw through the sharpness and forbearance in her eyes, and the two formed a secret alliance and stepped into the turbulent court together.
Shen Jinci relies on resourcefulness step by step to gain a foothold in the court and compete head-on with Qin Song's gang members; Xiao Fuyun also resolutely gets involved in the dispute over the throne in order to protect her and the people of the world. As the investigation deepened, Shen Jinci's identity was almost exposed, and Qin Song even colluded with foreign enemies and attempted rebellion, putting both his family, country, and personal relationships in dire straits.
In the end, the two cooperated internally and externally to put down the palace rebellion, overthrow the traitor, and the Shen family's injustice was cleared up. Xiao Fuyun ascended the throne to govern the country and ushered in the prosperous Qingming era; Shen Jinci put down his hatred and stayed with him. In the chaotic world of power and conspiracy, they guarded the mountains and rivers thousands of miles together, creating a legend of family and country justice and two-way pursuit.
