I just want to make a clarification about this novel. As you can understand this novel is a kind of isekai/reincarnated story but it will not be the classic story with the overpowered main character who destroys everything in their path.

In the beginning I wanted to make the main character overpowered but then I changed my mind and decided to make a more realistic progress to their power.

Also in volume 2, the things will completely change, of course I'm not gonna spoil anything but please continue reading this.
