Feng Qingge, the legitimate eldest princess of Great Yan, was banished to the cold palace for three years. Relying on a psychic crow to deliver messages, she unearths her late father's imperial edict and her late mother's relics, obtaining the phoenix-patterned jade pendant to unlock the Nine Heavens space. That jade pendant came from the extreme cold of Mobei, and beneath the ice sheet, a dead crow was also sealed—none other than Xiao Jiu. Millions of years ago, human civilization advanced into the quantum world, sealing the consciousness space into the jade pendant and implanting a scientist's consciousness into a crow. The world was destroyed, and it has been frozen in ice ever since. The crow thawed, searched for the jade pendant, and arrived at the cold palace. Relying on this jade pendant and this crow, Feng Qingge calculated her every step, publicly exposing her uncle Xiao Jingyan for poisoning the late emperor and forging the imperial edict, deposing the emperor, ascending the throne, and becoming the very first empress of Great Yan.
