Yan Yunshu, the eldest princess of Dayan, fell into a lake on the night of palace changes and traveled through thousands of years. She woke up in the bizarre Shanghai Bund in 2026. The neon lights are dazzling and the iron beasts are roaring. The once prosperous people have become strangers on the streets. Their identities are a mystery, and they are hunted by mysterious forces across time and space. She unexpectedly meets Lin Che, a student in the Department of Archeology - the Tang Dynasty murals he studied have exactly the same appearance as hers. When the secret of the bronze tripod, the intervention of the Space-Time Administration, and the truth about the chaebol experiment emerged one after another, Yan Yunshu discovered that his time travel was not an accident, but a key part of a thousand-year conspiracy. With red makeup reflecting the neon lights, can she keep her true heart in the confusion of the prosperous age and rewrite the fate of two eras?
