Three Kingdoms Dragon

Zhang Yu, a young man in the early 21st century, accidentally traveled to the late Eastern Han Dynasty because he continued to surf the Internet during the holidays. In this world, the world is in turmoil, the people are in dire straits, people are starving and dying everywhere, the Yellow Turban Uprising broke out, and the princes are fighting. Let's see how the young man survives in this troubled world and makes his way. Oops, the steam engine can't be invented, can't I invent a bicycle for transportation? Can't I invent the gun? I can use nitrate, disulfide, and charcoal to make gunpowder... Mr. Kong Ming, I want to learn from you. This novel and its characters are purely fictitious.
