Transported to a world governed by game mechanics—complete with stats, monsters, and skills—Jan discovers he's fundamentally unprepared. A devoted bookworm who'd never touched a controller, he compounds his disadvantage by bypassing the tutorial entirely. His only escape route: scaling a treacherous tower of a hundred lethal floors. Death carries genuine weight here, the world's mysteries remain largely unexplored by previous adventurers, and Jan must decide whether he'll succumb to impossible odds or become the unconventional hero this reality desperately needs.
