Yan Shi (宴世: Golden Age) was a daughter of Immortal Emperor Mu Zhuo's descendant and pure-blooded Charming Spirit. Like her mother, she was a disciple of the Gu Chun's Four Branches.
She became the third Immortal Emperor of the Gu Chun's Four Branches and created its last Branch, the Golden Era Palace.
She chose title "Yan Shi", because under her reign, the Nine Worlds entered the golden age of peace.
Yan Shi was an unfathomable Immortal Emperor; in the minds of the Charming Spirits, her achievements were incredible. She was someone comparable to their first emperor, Immortal Emperor Gu Chun.
