Li Bin, a materials science researcher, traveled to a different world and became a poor lord in the dying territory of "Greystone Town". There are only four hundred old and weak people left in the territory, and even the tax collectors are too lazy to come.
While others were cultivating fighting spirit and reciting spells, he activated the civilization lord system - analyzing all things and unlocking lost technologies.
Slag smelts source steel, soil blast furnace defeats knights, and steam engine crushes magic tower.
This world is just an abandoned experimental site for civilization, and he holds the key to restarting civilization.
