Li Wei, a dual PhD in chemistry and physics, transmigrates into the body of a poor scholar. Facing hostile outsiders, a decaying court, and backward technology, he may be physically weak, but his mind is full of world-shaking knowledge.

He only wanted to make money quietly and live in peace, but is forced into the conflicts engulfing the realm. From an obscure commoner to an imperial strategist, every step he takes sends tremors through the old world, bringing it closer to collapse.
