Punish the Wicked, Reclaim My Throne - Episode 1

Thrown into an ancient army as cannon fodder, a top-tier assassin awakens among Northguard recruits while villagers beg officers to spare a young man. An arrogant corporal seizes control, demands obedience, forces kneeling and humiliations (a color test, shoe-licking) and threatens the men with the front. When one recruit resists, the corporal moves to punish him; the assassin intervenes and kills the corporal with lethal skill. The camp erupts as "Kill-to-Grow System activated" announces a level-up and stat gains for the Host, leaving the camp unsettled and eyes turning toward him.
