A modern down-and-out Kochi (proficient in mathematics, physics, chemistry, astronomy and geography) accidentally traveled through time, and his soul penetrated the body of a low-level farmer during the California Gold Rush in 1848. Relying on modern knowledge to reduce dimensionality, you can quickly accumulate capital in the barbaric and chaotic gold rush era, build your own modern town (gold rush town), and become the overlord of one party; after accidentally discovering the time travel tunnel, you can use gold to cash out across time and space, return to the modern era and rise from the bottom of society, slap your predecessors and snobbish circles who dislike the poor and love the rich, gain true love, and realize the refreshing closed loop of "diaosi counterattack" in dual time and space. The overall tone is positive, taking knowledge as the core competitiveness, rejecting vulgarity, and focusing on counterattack growth and value realization.
