Lord of the Ashes: From Sunken Courtyard to Fortress

Transmigrated into a foreign world, he finds himself the last scion of the fallen Ashwood family, charged with treason and sentenced to exile as a frontier lord on the desolate Blackthorn Wastes. His assets: four hundred starving refugees, fifty loyal family retainers, and nineteen days of rations. Fortunately, he awakens the [Heart of Ten Thousand Craftsmen – Architectural Master System], which reduces material and labor costs for all constructions to one-tenth of normal. Even better, this world's "building mages" can erect structures through magic. "So with one-tenth the cost, I can build a Great Wall using spells?" From rammed-earth huts and sunken cave courtyards to fortified walls, water filters, solar cookers, and triangular spearheads, while others struggle merely to survive the wasteland, he launches a full-scale infrastructure project. This is the story of an architectural designer traversing dimensions, starting from a barren wilderness, using civil engineering and construction magic to raise an impregnable bastion step by step—and of the last Ashwood, who carves his path back from exile to the capital.
