我在异界修魔法

Xiao En, who was working on a virtual world learning machine, died in an accident, and got isekai-ed to a magical world with the learning machine (AI) that was a slut in the inside but has a pure elder sister appearance. The time in the virtual world learning machine’s space is ten times slower, and with this endless time, it can surely create the greatest new generation of outstanding masters!
