(I impulsively started writing this book before I had a good outline. The front part was crooked, which made it difficult to write later. I originally locked the text, but every time I opened the code word software and saw this book, I couldn't bear to see it, so I posted it anyway. I'm really sorry for the readers who are following me (T^T))
Highlight——
The cover was made by an appointment with an art teacher. It was only a cover, not a character drawing.
Intention: Master and disciple are in harmony, everything will be prosperous
