Impersonating Lord: Awakening Intelligence System

In a hierarchical medieval fantasy world, with a letter of appointment, a seal, and a ring, Segros embarked on the road of pretending to be a lord. A time traveler who was illiterate because he was born a serf in another world, faced with the pressure of being recognized by the complete aristocratic system, continued to build his own territory, establish the loyalty of the people in the territory, and build an army... Even with an intelligence system, he is still walking on thin ice. "The falsehood will be exposed one day, but it doesn't matter, until then, I will be the real lord."
