Western Fantasy: from Exile on the Frontier to Unified Continent

[Western fantasy lord + farming + multiple female protagonists + conquest + strategy] The sacred summons once in a century was originally a summoning artifact, but due to an accident, it changed into a living person and summoned a young man from Blue Star who didn't know the heights of the world. He cannot bring power to the kingdom like a normal summoned holy object, and the words he speaks are too shocking and have no respect for the holy Lord. He was ostracized by almost everyone and was classified as an alien, even an accomplice of the demon clan. He had no choice but to leave the royal capital voluntarily and go to the chaotic war zone to find another way to make a living. Many years later, when the king, the pope and the devil looked at the blood-red flag in front of the gallows, they would definitely think of the afternoon when the young man took the initiative to apply to go to the place of exile on the frontier.
