Joe in medieval fantasy world

Plot: Joel nickname Joe is a not so handsome and not so bad guy but has a boring life. One night while reading LN's on his smartphone, a message appeared stating "Do you want to elevate your life?" Sender: True God He then was teleported to Infanadah, a harsh world of magic and conflicts, where anything you can think of can lead to death. By gaining knowledge from two worlds, he tries to develop his survival and magical skills or any other methods as he tries to live here and make his life enjoyable. Why did True God choose him? Why is he sent there? Does he have a mission? He is not your typical pitiful bullied or betrayed MC. He is just bored. This is my first time writing a novel so please don't be harsh on your reviews. Tags might change in the future.
