Modern forensic examiner Lin Shuyue blows up her lab, then opens her eyes to find she has transmigrated into the body of a disgraced concubine banished to the Cold Palace! The System says this ancient world's timeline has gone wildly off course, and she must become a "corrector of time and space" to set it right. To make matters worse, three illegal transmigrators have also turned up. A corpse in the Cold Palace has modern nanogears hidden inside it, the data on a prince's chip matches her lab explosion case, and even Consort Shu's hairpin has been altered into a surveillance camera. How is this ancient world even more high-tech than the modern one?
She uses her forensic instincts to detect strychnine in poisoned soup, fights a humanoid robot that can crush a person's throat in the Hall of Mourning, and finds a bronze box in a dry well that matches the jade bangle on her wrist. Most astonishing of all, when the embroidery on a prince's swaddling clothes is pieced together with the carvings on the Cold Palace's stones, they form the star chart of a modern observatory! At midnight, the palace undergoes a "change of eras": ruins from a former dynasty and modern scenes overlap, and even her late mentor wanders around the star-gazing platform in ancient official robes...
The System glitches every now and then for 0.3 seconds, and she catches glimpses of herself in a lab coat in the mirror. While trying to stay alive in the inner palace until the Winter Solstice ceremony, Lin Shuyue unpacks the triple mystery of the star chart, jade pendant, and chip. Just as she's about to expose Consort Shu's secret identity, the System suddenly reports an error, hinting at a higher-dimensional "puppet master." This transmigration is more mind-bending than an autopsy! Watch as the forensic heroine follows the ripples of midnight through the cracks between past and present, examines corpses, solves crimes, exposes the transmigrators' conspiracy, and uncovers the secret of her mentor's thousand-year journey through time. It's an ancient-world version of "Werewolf in a Time Warp," and it's thrilling!
