The Yang family has devoted themselves to the Ming Dynasty and been loyal to the Ming Dynasty for many years, but the head of the Yang family committed treason and regicide at the triumphal banquet of the eldest daughter of the Yang family, Li Qiuyi, and was eventually stabbed to death.
But Li Qiuyi didn't know what happened that day. She also didn't believe that her mother could commit treason. In order to investigate the truth and avenge her mother, Li Qiuyi continued to work for Mingcheng.
Later, she was secretly assigned by King Mingjo to go to the once-defeated country of Bei Mi to inquire about the whereabouts of the demon god in folk rumors.
To this end, she visited the Beimi Kingdom as an envoy and met Princess Yizhu. From the Beimi people, she learned a secret that was difficult for her to accept.
