What will happen after the company? (Total War: Three Kingdoms)

He played for Cao Cao, declared himself emperor, subjugated all the lands, gathered almost all the generals, dressed and shod, fed and watered, all the provinces were pumped to the maximum, all the reforms were studied, everything is fine. The only thing haunts, tk. i'm a perfectionist. When I defeated the last faction and captured the province, a notification appeared (after about 5-7 moves) that I received the book of the earth, after so much time the book of heaven, and after that the book of people, restored some kind of treatise, but there was nothing and the characters of these notifications they said that only the world would help, and now there was 4 books left. No one knows, if of course the Three Kingdoms forum is still alive, how much longer do you have to wait ???
