How did MC get so strong? He had a few weeks of training with the knight, and a swordsmanship skill. Description of level 1 and level 2 of the skill sounded like beginner bonuses. Story hasn't explained what MCs other stats are, if they're way higher than an ordinary person. Only that he seemed to perform unexpectedly in a spar against his knight, but it wasn't clear whether his knight was fighting seriously or only putting enough effort to fight a child. Maybe having a skill is super powerful, even at level 2. Oh well
