Lanming Continent, this is a magical world.
There are three types of people in this world: magicians, ordinary people, and fallen demons. If you discover your magic talent at the age of 15, you are a magician; if you become a magician and have improper thoughts and go astray, you are a demon; if you are ordinary and have not awakened magic at the age of 15, you are an ordinary person.
(Maybe it's a bit like Douluo Continent and Hogwarts.)
Intention: Don't look down on every weak person around you.
