Three Religions and Nine Streams

I exist, but it seems that I have never appeared. The world is like a blank sheet of paper in my eyes, but I pass by without leaving any trace. I don't know who I am, but I have quietly watched the changes of generations. I don't understand the meaning of my existence, and I don't know if I can be considered a god in the eyes of the world. It seems like I was once a human being, but I don't remember it. Ultimately all I could do was write down everything I saw. The moment I had this idea, there were countless lives born in this world, and I chose the one who was most like me, and that was him. This novel and its characters are purely fictitious.
