A science student travels through the troubled times of ancient times, without systems or plug-ins. With only the knowledge of physics and chemistry, he started as a merchant, farmed crops, forged magical weapons, and finally overthrew the tyranny of powerful ministers and established an industrial empire. Main plot: Fu Anqi, a top student in science and engineering, travels to the last years of the fictional "Great Wei Dynasty". During the Little Ice Age, famines continued and people were in dire straits. He possesses a prodigal businessman who is about to go bankrupt. Facing the pressure of creditors and the powerful, Fu Anqi used his knowledge of physics and chemistry (purifying refined salt, firing glass, and making cement) to earn his first pot of gold, and signed a "contract marriage" with the wealthy daughter Su Waner who was in decline to seek asylum. Fu Anqi knew very well that in troubled times, "people with money but no power are fat sheep", so he used the caravan as a cover to establish a well-disciplined "guard" in remote fiefdoms by improving farm tools, firing red bricks, and developing black powder. He managed the territory scientifically, took in the refugees, and resisted the suppression of Zhao Mang, the powerful official in the DPRK. From commercial monopoly to armed separatism, Li Ge worked step by step, using advanced productivity and tactical thinking beyond the times to crush the cavalry of the old era, and finally became the world leader and ushered in a new era.
