Some of the language issues in this book are explained here.

All the author's ideas of a thousand years ago are from the source or some observations, so it is difficult to cover everything, the author really does not have the ability to figure out how the primitive tribes spoke, and I can't be sure of how the ancient Chinese people talked, so I can only slightly control the text in order to try to express the background of the characters, and the context of the conversation.

In fact, if I could figure out everything, and then write the ancients who spoke in Yayan, and used the language of primitive tribes, I believe that no one would read what I wrote. Well, I guess I can switch to ancient history research, or I can also make a cameo appearance as a diplomatic translator or something~

I said a few more words, please forgive me for the verbosity.
