Otaku Travels to the Three Kingdoms

My name is Yang Dan, an engineering otaku born in the 1980s. I traveled to the late Eastern Han Dynasty. Before I was excited for three seconds, I discovered that my host was an ordinary farmer, at the bottom of society! According to the basic routine of time-travel novels, as the male protagonist, I must first make money, then make steel, then develop hot weapons, and finally wipe out the world. But how to make money? Making soap, sugar, glass... I don't know how; steelmaking, gunpowder... Hey, all the knowledge has been returned to the teacher. Lying flat in troubled times, one would either starve to death or be beaten to death. It was a rare time to travel through time, which was a bit of a loss. But how to deal with the start of Tianbeng? Fortunately, I am a fan of the Three Kingdoms. I have read Romance of the Three Kingdoms and played the Three Kingdoms game. Diao Chan, Xiao Qiao, Zhen Luo... Thinking about it makes me excited (slobbering) Well, maybe I can get by if I work hard, but how and how can I get along? Everything starts from the word "Gou".
