The Only Thing I Can Upgrade Is Strength
A young man with Muscular Dystrophy finds himself transported to a fantasy world. This world has levels, which allow people to improve themselves beyond the norm. Given such chance to improve himself, he immediately thinks of his biggest weakness. Through a careless choice of wording he ends up with the ability to only increase his Strength stat. Since his base is so pathetic, merely a tenth of normal, he ends up with merely passable Strength. How will he overcome his problems to survive in a world that he knows nothing about… including where the nearest city is?
