In the first episode of the 94th TV series Romance of the Three Kingdoms, where did Liu Bei say it at Zhang Fei's house? It doesn't seem to be in the novel.
No, it's a TV script with lines. "At that time, I didn't know who the world in the domain was." Such a sentence is absolutely impossible for Liu Bei to say in the original Romance of the Three Kingdoms, because the original focuses on the positive image of Liu Bei's "loyalty" to the Han royal family, and he would never say such a rebellious thing.
