In her third year as a drifter in Hengdian, Xiao Yiru is still a low-level extra without a single line, until she finds a strange man on the set of The Romance of the Sui and Tang Dynasties.
He claims to be Yuwen Huaji, the late-Sui warlord from the history books who murdered an emperor, proclaimed himself king, and was eventually beheaded. He has been reborn on her film set.
He has no idea what air conditioning is, can't tell a toilet from an imperial throne, holds a phone like the Imperial Seal, and doesn't know how to order delivery.
But his martial skills are unmatched on set, and his political schemes can turn the world upside down... Once capable of toppling an empire, now he bows only to her.
Others laugh at her fate as a bit player. He stands in front of her.
From an oppressed nobody to an award-winning queen of the screen, he stays by her side with his sword in hand at every step of her rise.
Meanwhile, his twin brother, Yuwen Zhiji, has also crossed a thousand years, but chosen a different path. He joins the underworld, hoping to become king once more in this peaceful age.
Brothers at odds, old and new worlds colliding. In this life, he abandons his ambition to rule for a thousand years, choosing instead to stand by her as she rises to the top and becomes an empress of the screen.
