Isekai Walking

Sora, a Japanese man summoned to another world, gained the skill of "Walking." Its effect is that "no matter how much he walks, he never gets tired." Because of his weak skill, the king expelled him from the hero's party. But when Sora started walking in the other world, he started leveling up! It turned out "Walking" also had a hidden effect of "gain 1 experience point for each step taken." As he walked, he acquired useful skills such as appraisal, alchemy, and healing magic...... one after another, he became powerful just by walking! His adventure to explore and encounter the unknown is about to begin!
