Hell's Resonance

In front of absolute power, everything crumbles . . . If Ethan could choose which person he'd reincarnate into, he'd choose the strongest person in his favourite book- the ever powerful protagonist, Noah. Somebody who has his powers practically handed on a plate with the help of his omniscient, overpowered system. And to his delight, Ethan gets reincarnated right where he wants. Except, he's not in the body of Noah. And he definitely doesn't have a system. In a world where monsters threaten humanity's existence, powerful humans called gatekeepers venture into gates, risking their lives to protect everybody. But the path to a gatekeeper is not an easy one. Can Ethan make it to the top? Can he hope to grow as strong as the protagonist? Can he survive in this period of turbulence, where Noah's presence shakes numerous forces, both within and outside the planet? And most importantly. Is Noah really as amazing as Ethan thinks?
