Golden Mage

I lived a life repaying my parents’ debt and died unjustly.
“It’s unfair that I died after living a lonely and poor life!”
But after opening my eyes in place I’ve never seen before, I became Ell. In order to protect his family in this life, Ell needs power and money.
“I’m going to become the best mage and obtain both.”
Ell will obtain everything in this life by using his management skills as a pro-gamer from his past life and his genius-level mathematics !
