Ren Nan, a female CEO in the modern business world, died unexpectedly. Her soul traveled to the Southern and Northern Dynasties and possessed Feng Xin'er, the princess of Beiyan whose country was ruined and her family was ruined. On the verge of death, she was rescued by Li Weiyang, a concubine of the Northern Wei Dynasty's Shangshu Mansion, but the latter died trying to protect her. Ren Nan, who was burdened with a double blood feud, had to take on the identity of "Li Weiyang" and sneak into the capital of the Northern Wei Dynasty surrounded by enemies.
She carries a deadly secret - once her true identity is exposed, she will surely die. In the Shangshu Mansion, the surveillance and bullying of the aunt Chi Yunrou (the sister of the villain general Chi Yunnan) are everywhere. Using modern business thinking, she established her own power in the cracks and secretly investigated the truth behind Yunnan's conspiracy to frame Beiyan and seize the mineral veins.
Dilemmas come with love. She was attracted to Tuoba Jun, the king of Gaoyang in the Northern Wei Dynasty, whose pseudonym was "Mr. An", but she didn't know that he was actually the time-traveled body of An Shubo, her rival in the modern business world. The relationship conflict is acute: he is the prince of a hostile country, and she is an avenger who wants to overthrow the foundation of his dynasty. Lies and misunderstandings continue to breed in the power struggle, and the countdown threat to Yunnan is approaching step by step - a conspiracy and palace coup to purge the Northern Yan remnants is brewing.
In the final showdown, she teamed up with Tuoba Jun and other forces to bring down Yunnan and rectify Beiyan's name. After the bitter victory, the two time-travelers put aside their past grievances and jointly created a new pattern integrating ancient and modern times with wisdom beyond the times. She grew from a subjugated princess to a legend who influenced an era.
