A celebratory toast at a hot spring banquet unexpectedly becomes the start of a journey through time! Finance mogul Lin Xiaoman, sanda champion Su Mingyue, and top anatomy student Zhao Qingqian are three close friends who encounter a strange phenomenon at a hot spring resort. When they wake up, they are dressed in finery and have married into the imperial palace, becoming the Crown Princess, a secondary consort, and a female official at the Imperial Medical Academy.
On one side are the rules of an unfamiliar dynasty’s palace; on the other, their modern memories and the keepsakes they brought with them: a Tiffany gold hairpin, a scalpel, stud earrings, and a mysterious pale-gold phoenix mark on a wrist. They must deal with the Second Prince’s “shoulder throw at the hunting grounds” and the Third Prince’s “modern-era hysteria,” while also unraveling the clues: a money-counting machine burn on a palace maid’s sleeve, a barcode-shaped birthmark behind her ear, and the secrets of time and space hidden in the Imperial Astronomical Bureau’s Treatise on the Armillary Sphere.
When calculations based on “thirty coins per dou of rice” collide with palace intrigue, sanda techniques meet a prince’s provocations, and medical knowledge faces strange ancient ailments, the three friends turn the palace upside down with their modern skills. Can they band together to survive their ill-fated phoenix destinies and uncover the truth behind the rift in time and space?
