A Reincarnated Glassmaker Builds a Base That Exists in Two Realities at Once! | Manhwa Recap

In the ordinary world, his settlement is poor and defenseless, but every mirror opens a passage to a dark parallel world filled with rare resources. The Dual Craft system allows him to construct buildings simultaneously in two dimensions and combine their properties. A full-grown mirror warrior, an alchemist, a scout, and a light mage become his allies and members of his harem. By controlling both versions of the territory, the hero builds an empire that cannot be completely destroyed.
