Rule Horror: I Use Simulations to Conquer the Eerie Forbidden Zone

In the era of Blue Star’s cataclysm, eerie forbidden zones descended across the globe like a plague. Mountains, forests, towns, and old houses transformed into deadly dungeons governed by lethal rules. Everyone who turned eighteen was forcibly drafted and sent into the forbidden zones to survive. Failure meant total annihilation. Only those who cleared a zone could gain cultivation, resistance to the supernatural, and resources for survival. Strength became the only law. The forbidden zones had a strict hierarchy, from white to rainbow rank, with the danger multiplying at every level. Rumor had it that these zones were not natural disasters, but remnants of the rules left behind by a war in an ancient era. Their depths sealed away a terrifying source, and a new cycle of eras was already drawing near beneath the surface.
