I Have 3 Months to Live. A Prisoner Beauty Wants Me. I Used Physics to Conquer an Empire.

A STEM grad wakes up in the Great Yu Dynasty with only three months to live. No money, no food, a bully trying to steal his land, and two mysterious female prisoners dumped on him. No cheat system, no golden finger – just raw knowledge of weather, soil chemistry, saltpeter, tool-making, and metallurgy. In a world that eats the weak, he has to calculate his way to survival – and calculate his way back home. Luo Wenjie opens his eyes to find himself as a dying outcast in a border village of the Great Yu Dynasty. Ninety days left on his life clock. The grain jar is empty. His land deed is marked by a local thug. And chained beside him are two prisoners whose identities are a complete mystery – one of whom stares at him every night and says flatly: "Lie with me, and I'll keep you alive. This isn't a power-fantasy novel. No system windows pop up. No heavenly treasures fall from the sky. All he has is a limited but sharp memory of climatology, soil science, fermentation, basic metallurgy, mechanics, and human physiology. His path: survive the winter. Fight from village to county town. Rise from refugee to foot soldier, from soldier to strategist – until he stands in both court and battlefield, dissecting the rotting bones of a dying dynasty. And the most beautiful and cold-blooded prisoner among them? She holds the only clue to getting him back to his modern world – but her price is nothing less than the entire realm. In a world where men devour men, he wields knowledge like a blade. When his final day strikes, so does the truth – Go back to the world he came from, or stay in the dynasty he has reshaped with his own hands? Luo Wenjie's answer is far crueler than you think.
