Lord of the Underworld: A Hundred Ghosts March Across the Heavens

In a world where everyone can change their class, betrayal strikes from the most unexpected place. Stripped of his elite SS-class occupation in broad daylight by his own father and handed over to his half-brother, he refuses to accept such a fate. Armed with a cheat-like system, he awakens the supreme celestial class: the Ghost Monarch. By harvesting grievances, he evolves terrifying spectral entities, summoning everything from wandering spirits and underworld soldiers to ancient mythic hydras and the primordial source of all impurities. When dungeon raids begin, his domain of ghosts rolls over all obstacles. During the national martial arts exams, his spectral army stands alone against the nation's finest. And when alien races and abyss demons dare to invade, the true Lord of the Underworld steps forward to claim dominion.
