Ruin Artisan [LitRPG / Base-Building / Crafting][Book Two Complete]

In the slums of Sanctum, the "cleansing" of the sick is a divine miracle. Or so the High Lord claims. Ren Silas trusts only in gears, structure, and cold, hard physics. When the deadly Rot threatens to consume his little sister, Ren breaks every law in the city to save her. Cornered by guards and under crossbow fire, his final act of protection is to hurl her into the High Lord’s "miracle"—a machine that looks suspiciously like a grinding industrial furnace. Condemned to the Deep Wilderness for the crime of trying to save her, Ren hits the mud with 1 HP and a ruined shoulder. The High Lord intended for him to become fertilizer. Instead, the fall awakens him as a Ruin Artisan. Clutching the encrypted leather Grimoire his father left him, a single piece of inherited advice finally rings true: Don't fight the dungeon. Dismantle it. Armed with a System interface that reveals the structural blueprints of reality, Ren constructs bases, weaves conductive monster hides into reactive armor, and turns gravity and leverage against the labyrinth's predators. But he isn't alone in the dark. His newfound Tenacity has awakened a ruthless inner voice—a dark, pragmatic survival instinct that weaponizes his guilt and constantly pushes him to shed his weakness. To march back up the Spire and reclaim his sister, Ren needs more than scavenged scrap. He needs an empire. Alongside a fiercely loyal two-ton siege golem and a shattered High Arcanist entombed in living ironwood, this broken pack sets out to overthrow a tyrant. The cost of power is steep. To forge the ultimate weapons, Ren uses ancient machinery to carve out his own memories, hunger, and empathy for material. He is sacrificing his humanity piece by piece to become a stoic, calculating architect of war, relying on his allies to keep him grounded before the ghost in his head takes over entirely. High Lord Valerius thinks he sentenced a rat to death. He's about to find out he handed his enemy the blueprints to his destruction. What to Expect: Weak-to-Strong Progression: Ren starts at Level 0 with 1 HP and claws his way up through grit, strategy, and creative crafting. Physics-Based Magic: Combat is solved through structural breaks, altering mass, and exploiting environmental geometry. Deep Base Building: Upgrading a ruined generator room into a heavily fortified underground empire. Psychological and Physical Cost: A protagonist battling a dark, pragmatic inner voice, hollowing out his mind alongside a System that takes biological tolls in exchange for power. Found Family: A grim but deeply loyal party featuring a giant, child-like mechanical golem and a legendary, broken mage.
