Yunya is a mixed continent that includes students of all nationalities, with Chinese being the largest group. It is a completely independent continent. You can go to other continents at any time, but once you go, you can never come back without a pass, and it will erase your memory of Yunya.
In Yunya, there is only one school, called Yunya School, which is divided into kindergarten, elementary school, junior high school, high school and university. People can learn a lot of knowledge there that cannot be learned on other continents, such as magic and so on.
