At the beginning of the Hongmeng, a book of omens was sent down. Mortals can learn from it, and they can observe the spiritual methods of heaven and earth, and control the methods of natural forces. They also issued an order to seal the monsters, looking for the monsters in the world to become immortals, filling the vacancy of earthly immortals. When they encounter good things, they will be sealed, and when they encounter evil, they will be cast down...
Purpose: Seek what is right and what is wrong, distinguish right from wrong, and have many worries when walking the path.
