Reborn in another world as a poor farmer, a boy named Ars uses memories of his past life to improve his family’s fortunes. The kingdom is troubled by a declining royal family and ongoing unrest, while Ars begins tending the land in a remote village. Fond of city-building games in his former life, Ars applies his knowledge and magic to improve crops and build houses. When he learns to make bricks, he sells them to a peddler and receives a rare egg belonging to a tamed beast. This is the beginning of the story of the boy who will one day be called a “Living God” and found a nation.
