Siegebreaker: Architect of a Broken World [LitRPG Isekai]

Mages chant ancient spells. Alex builds reinforced concrete bunkers and steam-driven kill zones with his brutal Siegebreaker OS. An engineering student falls from a construction site and lands on a cat-kin queen in the shattered world of Valsalia — a realm of floating islands, broken gravity, and monsters that treat humans as snacks. Armed with physics, industrial know-how, and the ruthless Siegebreaker OS that turns blueprints into real fortresses, Alex brings cold logic and raw industrial force to a world ruled by chaotic magic. What to expect: Hardcore tech system:Siegebreaker OS with color‑coded protocols, achievements, and blueprint unlocks Industrial base‑building:from crude walls to automated turrets and kinetic bombardment Science vs. magic:exploiting physics loopholes instead of learning spell lists Competent, ruthless MC:solves problems with leverage, explosives, and very little mercy Kingdom‑building:resources, population growth, economy, and multi‑race alliances No harem · slow‑burn romance Progression Fantasy · LitRPG Chapters release: Monday - Wednesday - Friday Welcome to Valsalia. Let's break some gods.
