By the way, there are two books in the bookstore located in Fontaine's court. One is called the time traveler (someone from Fontaine was able to travel to the past and the future) and the other is a book with the history of Kaenhria, from there you can get good ideas
I will be honest;I straight up forgot that Isaac went to Liyue and meet a few characters there like Xiao and Hu Tao.It was such a one-time thing and happened so long ago and didn’t really matter to the story or plot of this fanfic that I just forgot about it.
