Who can tell me to learn yin and yang! What should I learn first?

Learn divination to predict special monsters first. If you want to learn divination, you must first learn to watch stars. If you want to learn to watch stars, you should first find some astronomical books to read. You should know where each star is, the position of 28 stars, the zodiac signs, and how to judge the Big Dipper and the North Star. Besides, I think you look like a novice. Never use more advanced spells, or you will hurt yourself. I have answered your "Yin-Yang taboo" before, and your correct answer can be called qq306353794.

Hee hee!
