Empress Demotes Me to Mine, I Take Over the World

Assistant Grand Preceptor Pei Changyuan aids the Empress in restoring the realm, but his excessive merit leads to a imperial decree banishing him to the barren County of No Grass. Heartbroken, he decides to simply survive and develop, yet he applies modern physics and chemistry to drill wells, smelt glass, and manufacture cement in the desolate mine, transforming the wasteland into an industrial hub. As the Northern Border falls and the Empress seeks peace, he retakes the frontier in three days and captures the Northern Barbarian Wolf Lord in seven. But this time, he does not serve as anyone's blade; he aims to change the way the common people live.
