As a child, Gu Ping’an and her three siblings were hunted by the Empress. In a desperate escape, she accidentally fell off a cliff and was presumed dead. She was later rescued and adopted by an assassin named Xia Dachuan, who gave her a new identity—Xia Zhiyi. Years later, Xia Dachuan fell gravely ill. To save her adoptive father, Xia Zhiyi sold her most treasured jade pendant. Just as Xia Dachuan was about to reveal her true identity on his deathbed, he was interrupted. As a result, Gu Hongyun—a vengeful figure—mistakenly turned his hatred toward Xia Zhiyi. In order to clear her father’s name, Xia Zhiyi entered Wangyue Tower, where her fate took a dramatic turn. From then on, she became caught in a dangerous game of secrets and revenge.
