The Demon of the Three Kingdoms Becomes Uncle Liu Huang

I accidentally traveled to the Three Kingdoms, what? I have become Liu Bei, Uncle Liu? What to do if you don't have weapons? I have the strongest reality store, fine gold level artifacts, buy whatever you want! What should I do if I don't have enough to eat? I have the strongest reality store, specializing in Maotai, Manchu and Han banquets, buy whatever you want! What? There are no firecrackers in the Three Kingdoms? It's okay, I have a research and development department, and the fire blunderbuss turns into a demon blunderbuss! What? Is Hulao Pass easy to defend but difficult to attack? It's okay, I have a research and development department, Yao Yunfan rises into the sky!
