In a world where humans are often the prey, Hyeon-U Kim emerges from a 12-year imprisonment in a tower overflowing with regenerating monsters. Having survived against all odds, he's more powerful than just about any human or monster on Earth. Free at last, Hyeon-U is driven to uncover the truth behind his incarceration, a quest that will undoubtedly involve slaughtering hordes of these monstrous creatures – and, unintentionally, saving the world from their destructive grasp. Bangguseok Gimssi and Juyeong Hwang's dark fantasy adventure, Tower of Regeneration (2020), masterfully balances humor and high-stakes action, propelling Hyeon-U toward his destiny. As he navigates this treacherous new world, he'll confront the most formidable foes and unravel the mysteries of his past. This completed series is an unmissable read for fans of supernatural comedy and epic fantasy.
