Story
"Understanding" is "Stronger" than a Sword! There is no magic without any weapons! But! This is the story of a man who wishes to live safely! "So, I've come to a different world." That man stood alone in a mountain full of plants and creatures that he never knew nor saw before. He goes down the mountain by avoiding encounters with a big slime (and bandits), and is caught as a suspicious person in the castle he reaches.
