Strongest Bandit System

Starting with a mountain stronghold and two people (a military advisor and a groom), he aims to build the strongest bandit gang. He is transported to a chaotic world, inheriting a mountain stronghold on the verge of collapse. In this world of slaughter, will he choose to rob money, food, and women to live as a carefree bandit king, or will he spill his blood, clash with heroes, and strive for a name that will resound through the ages, asking: Can kings and ministers claim to be superior by birth?
