I Am an NPC from Romance of the Three Kingdoms

The three brothers in Taoyuan are sworn brothers. Why does Guan Yu, the oldest, worship Liu Bei as his eldest brother? What methods did Liu Bei use? Zhang Fei is tall and tall. Not only is he good at martial arts, but he is also good at calligraphy and is proficient in art and painting. He is versatile in both civil and military affairs. He is a popular male protagonist in online novels at the moment. Why did he become a dark and fierce rough man in the Romance of the Three Kingdoms? Mr. Luo Guanzhong recruited real characters from the Three Kingdoms and asked me, as an NPC, to direct them to complete the story process according to the content of the Romance of the Three Kingdoms without making any mistakes. If I make too many mistakes, I'll be in vain. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
