Sacrifice Mage Novel

Summoned and ritually sacrificed, Ross Moreland's wish for excitement is granted in the most unexpected way. Sent back to life by a rejected sun god, he now possesses a star-like mana core that surges with immense power. This volatile mana cannot be expended quickly enough with conventional spells, risking a fatal detonation. However, Ross discovers he can "sacrifice" this mana for incredible rewards. To control his burgeoning power, Ross must infiltrate the very cult that attempted to end him. Persuading them of his value as a cultist with a unique mana core proves surprisingly simple. His real challenge lies in mastering his abilities while navigating a world filled with treacherous nobles, fanatical vampires, and a sunless city that preys on the weak. Fortunately for Ross, it's his turn to wield the power of Sacrifice. This story promises an isekai adventure with elements of training, magic exploration, slice-of-life moments, dungeon delving, and eventual cult-building, presented in daily chapters for the first month, followed by a five-day weekly schedule.
