This book is also known as Cold Palace Sign-In: The Abandoned Consort Starts with Tiangong Kaiwu.
Lin Wei, a modern office worker, transmigrates after dying suddenly into the lowliest abandoned consort in the cold palace of the Great Yan dynasty. Starving and freezing, she binds herself to the “Keep a Low Profile and Don’t Get Reckless” System. She only hopes to scrape by, but the System’s rewards grow increasingly outrageous: from hybrid rice to blueprints for flintlock guns, from the Industrial Revolution to making the nation strong through science and technology. She farms and makes medicine while secretly building her own power, quietly changing the world from a corner of the cold palace. And the emperor who once looked down on her, Yan Zhaoyu, will eventually discover that the woman he personally cast aside is no good-for-nothing, but the one key to his dynasty’s rise.
