Chen Wei dies beneath his collapsing skyscraper, a final monument to flawed modern ambition. He awakens as Shan Jian, a prince exiled to a drowned, dying province. But within his mind now lies the Architect’s Ledger—an interface born from the fusion of an engineer’s logic and a world’s fading magical ecology. It quantifies the land’s sickness: poisoned rivers, sleeping groves, structural decay. Armed with this second chance and a ghost’s guilt, he must rebuild. Not for glory, but for life. He will marry hard science to ancient wisdom, turning engineering into medicine for the land. His new purpose: diagnose a dying empire, and build a blueprint for its healing. This is the rebirth of the Jade Engineer.
