Plague of Death

From a life plagued by death, Kim is suddenly thrust into a world different from Earth where mythological creatures such as vampires linger around. Coupled with humans who could be an incarnate of satan or other famed devil figures, Kim will have to carve out his own path of power to survive in such an evil world. But would life even be a foreseeable future for him? With a game-like system assisting him on his journey, what heights of power will he be able to reach in this world where his principles would be forced to change, resulting in his humanity being thrown out the window? --- Note: This is VERY fast-paced. There will be fights very constantly, obviously, I will give chapters for relationship development and bla bla, but besides that, it'll be very fast-paced.
