作品概要

In a different world, the royal family is in decline and turmoil continues. In a cold village, an infant named Ars has a memory of his previous life where he was passionate about "city-building" games, and starts building houses with his own magic to get out of poverty! He hatches a rare servant beast, cultivate the land, clear it, build Roman-style roads and castles... The heroic tale of a boy who will later be called the "living god" begins!
