Su Qingyuan, a top cultural relic restorer, is swept into the flourishing Tang dynasty under Emperor Xuanzong by a blue light from a gilded Tang-era hairpin! Stranded on the streets of Chang’an in a T-shirt and jeans, she is treated as an oddity, but her “family secret art,” actually modern restoration techniques, leaves the whole city in awe.
Lu Jingyuan, the cool and abstinent deputy commissioner of the Jing’an Bureau, runs into this “remarkable woman” while investigating a case. She can spot forged evidence and crack mechanisms, and even the fragments of the hairpin can point her toward clues, leaving him both suspicious and astonished. When danger strikes on the street, he coldly takes her side. When rumors spread, he proves her innocence. At the brink of life and death, he takes her hand and vows, “Wherever you are, Qingyuan, I’ll be there too.”
The gilded hairpin conceals the secret behind Princess Yong’an’s death and binds the two together by fate. Political enemies brand her a “witch” and try to sacrifice her, while a vassal prince’s rebellion unleashes bloodshed across Chang’an. Alongside a close friend who is a commandery princess and a gentle female physician, she forms a team of strategists and joins Lu Jingyuan in exploring ancient tombs and exposing conspiracies.
Modern restoration techniques meet the political intrigue of the flourishing Tang dynasty, and a cold-faced deputy commissioner meets a sweet wife who has transmigrated through time. Amid flashing blades and sweet everyday moments, they must protect the peace of their country and find their way to a love that goes both ways, ultimately creating a celebrated Chang’an romance!
