Supernatural: Shanhai Bookstore, I Accept a Zombie as My Sister

I decided to use the skills taught by my master to observe the psychology of life, do some casual arithmetic, and act according to the circumstances. But the master gave me a bookstore. I thought that after inheriting the master's bookstore, I could be a salty fish boss and wait until death. I didn't expect that this was a bookstore that dealt with the Three Realms and Six Paths. Someone said in a poem to encourage learning: "There are thousands of bells of millet in the book, there is a house of gold in the book, there are horses in the book like clusters, there is a face like jade in the book." Why are all the monsters and ghosts and beings in the spiritual world swimming in my book? The world is divided into yin and yang. What I do is the business of yin and yang, and my bookstore is my treasure. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
