During the later years of the Kangxi Emperor's rule, his many sons were vying for the throne. The fourth prince, aided by Lusi, Nian Gengyao, and Han Chong, while the fourteenth prince had the support of martial arts master Zeng Jing. The competition between the two became intense. Lusi developed a romantic relationship with the fourth prince while Zeng Jing also had feelings for her, making their situation more complicated. Later, the fourth prince killed Kangxi and altered the imperial edict, successfully usurping the throne and naming himself Emperor Yongzheng. From then on, Yongzheng ruthlessly eliminated dissidents and even betrayed those who helped him, causing Lusi to regret her involvement. Ultimately, the fourteenth prince plotted to assassinate Yongzheng with the help of Zeng Jing and Lusi, igniting a fierce battle.
