My Days and Nights with the Lord of Mysteries

(One day I suddenly came across a promotional video for the Mystery game from a certain video software. I recalled reading the Lord of Mysteries novels a few years ago, and I always wanted to write something. This story is based on the world view of the Lord of Mysteries, and does not involve a certain circle. It is also an impulsive work, and I am not sure where I will write it.) Ps: I have read a lot of novels over the years and have been contaminated by a lot of strange knowledge. If there is a familiar plot that everyone sees, it is purely a coincidence that I am walking on the path pioneered by my predecessors.
