Rebirth: I Rely on Physical Chemistry to Subvert the World

An ordinary person whose edges have been smoothed away by modern society is reborn in the turbulent ancient times. Armed with seemingly ordinary junior high school physics and chemistry knowledge, he started from providing food and clothing, making salt and iron, improving farm tools, inventing sharp tools, building workshops, developing the economy, and training new troops... Step by step, he transformed the power of science into the power to change the world. He gathered refugees, recruited heroes, fought against clans, put down rebellions, and defended against foreign enemies. He used his "miraculous" "magic" to subvert the understanding of the times and quietly change the destiny of the empire. In the end, following the will of the people and the general trend, he stood at the pinnacle of power and created an unprecedented era of "scientific empire".
