🚨 She became the doomed Cold Palace maid—then built a toilet, brewed penicillin, and turned exile into a kingdom. But the heroine she saved flipped…

Ji Wanxing was just a modern STEM woman dropped into a novel as the disposable maid. When she tries to stop Consort Yun from making a dangerous palace move, she gets blamed, dragged into the Cold Palace, and mocked by Consort Lan. Ruins? Check. No food? Check. A cold-faced guard commander who saves her on the road? Unexpected check.

Then the whole dynasty underestimates her. She turns the Cold Palace into hardcore survival heaven: physics-powered plumbing, herbal penicillin, donkey-hide glue, secret markets, foreign trade—every “impossible” idea becomes a flex. And Pei Xizhao, the icy guard commander, becomes her shield, her business partner, and the man ready to defy every palace rule for her. Consort Yun watches the “cannon fodder” win hearts and wealth, turns green with jealousy, and makes a deal with a power-hungry eunuch.

But the real nightmare starts when the palace coup erupts, flames close in on their paradise, and Wanxing wakes up wounded right as Pei Xizhao kneels with a proposal. Can their Cold Palace dream survive the final betrayal—or is the original heroine about to steal the ending? 👇 Watch to find out.
