Isekai no Binbou Nouka ni Tensei Shita node, Renga wo Tsukutte Shiro wo Tateru koto ni shimashita

In a chaotic world where royal power has collapsed, a small child plays with dirt in a remote, frozen village. His name is Ars. Gifted with extraordinary earth magic, Ars can freely alter soil and terrain-so he puts his ability to work improving farmland and restoring barren fields. What no one knows is that he carries memories from a past life obsessed with city-building games. As he grows older, Ars sets his sights on escaping poverty. Using his own original magic, he begins constructing houses from scratch. He hatches rare magical beasts, clears the dense forest surrounding the village, and revolutionizes trade by building Roman-style roads. Massive defensive walls rise to protect against monsters, and a once-starving farming settlement slowly transforms into a thriving city. But rapid progress attracts unwanted attention. Nobles who see his development as a threat move to crush his ambitions-and Ars is forced into conflict with the powers of the world. Starting with nothing but his magic and ingenuity, a single boy reshapes the land and sets out on an unstoppable path toward unifying the realm. The epic tale of a nation’s founding begins with one child and a handful of dirt. (Source: Hanashi Media)
