Otherworld Territory Builder

Modern youth Jiang Ye transmigrates to a cruel otherworld full of monsters. He starts his survival in a monster-infested valley, choosing the high-risk talent "Architect's Dream" for double material/building yields. He collects resources, crafts weapons, trades, builds shelter, and fends off mutated monsters at night. As his residence upgrades, he takes in orphan girl Molly, sets up defenses, and grows into the lord of a territory who fights monsters and expands living space.
