Five Eyes and Easy Numbers Book

I remember when I was a teenager, I pulled a book out of a crack in the wall while playing in my old house at home. Although it is written in classical Chinese, the story is very exciting. There are many secret techniques, principles of Taoism, formation placement and other principles. Let me understand that these are not superstitions, but ancient science. It is also mixed with the worldview of the ancients, and there is a complete system in it. I almost read the entire book at that time. Then it was nowhere to be found. Don't know where to throw it. Thinking about it now makes me regret it. Fortunately, I remember most of the stories inside. I replaced it with vernacular and some additions of my own. Pass it on to everyone. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
