This is a birthday present for Gui Chuwan this year. Although the background is fictional, most of it is actually taken from the European religious reform in the 16th and 17th centuries. That is to say, the general background of the times and the direction of major events remain unchanged. I will mark and explain some places. Actually I write this because I am quite unfamiliar with that period of history OTL If you have any questions, please feel free to ask them, but please don't judge me too much QVQ
