Elysia: World where everyone has a unique system

The story takes place in the perspective of Killian Zeke in the world of Elysia where he trains to be a system officer in Neolith Academy. Elysia is world where monsters and dungeons in a modern fantasy setting. Every child once they turn 13-14, unlocks a system unique in relation to everybody else. Killian Zeke has seemingly acquired a weak system called the "Knowledge system". Even though Killian Zeke has a weak system, he strives to get stronger while unknowingly learning about the secrets of the world of Elysia. *Note* This is the first time I've ever written a story and I haven't really thought about the story in depth (I'm kind of winging it). This is more of a passion project, and I can't ensure quality. ):
