Due to this reason, she decides to live a quiet life in the mountains as an immortal witch in a 17-year-old body, after being reincarnated. His main source of resources comes from defeating the slimes that abound in the area to obtain magic stones, which he sells to the Guild in town. In addition to that, he often creates medicinal herbs. All of the above earns her the name “Witch of the Mountains,” and she lives to this day receiving respect and trust from people.
