It is said that "The Book of Mountains and Seas" was written by Xia Yu and Boyi. However, because its content is all-encompassing, the leaders of a clan and tribe can only become part of it. The responsibilities of wizards in various periods determine that they know everything about astronomy, geography, history, religion, biology, medicine, imperial lineage, major technological inventions, etc.
The wizard family records the secret skills passed down from their ancestors in books and passes them down from generation to generation. This is why some wizards have evil thoughts and become Black Teeth traitors.
The past and present lives of Xin Ning and Tang Moxi were also involved because of this ancient power... Killing one person made the world successful, but when that person was Xin Ning, everything changed.
