Going to the studio in minibuses before dawn, and dying in front of the camera is a common occurrence - Shen Du is the most inconspicuous extra in Hengdian, and can't even get a single line. Until Master Jiang Bo made a phone call late at night, a camphor box that unlocked by itself dragged him into a world that he never knew he carried in his blood: the nine-faced godhead of the ancient Nuo sacrifice, lost to the world, and guarded by the secret organization "Liyuan Division" for generations. There are no natural disasters in peaceful years, but "epidemic" quietly breeds through "drama" - roles are played repeatedly, emotions are exaggerated repeatedly, and "drama ghosts" will be born in the gap between actors and roles. Shen Du awakened the latest, but holds the most powerful "powerful position". The "Chi You" mask that was stolen from the Liyuan Division headquarters thirty years ago and whose whereabouts are unknown is now entangled with his life and blood. Popularity, association, life experience, civil strife, awakening, war... A boundary battle between consumed "characters" and "people", a three-thousand-year curtain call of obsession and redemption, has begun.
