This idea of mine came from a thread I read and I wanted to share this with you guys since I might not write this off. 

First off, we start with an MC whose known to be the strongest in his clan and always solves his problems with brute force. He gets hired to defeat a strong foe one day and almost died due to someone betraying him. That is until he discovers a mysterious egg that he found and bonded to him. 

This egg is a Educational System that helps the MC get smarter, becomes less of a dense guy and acts mature to which he slowly let go of solving things with brute force and starts to solve things through mathematical analysis and science. He also started creating magic, working on forging magical weapons and even joins in on a political battle and becomes a king who not only started managing a country but also uses less of his muscles and more of cunning and schemes.
