Reincarnated by Giffen

A black African man goes from hustling on the streets and trying to move up from the bottom of the food Chain to dieing when he tries to go off character and save a damsel in distress with a wardrobe malfunction and gets reincarnated in the body of a white boy in a new world with fantasy creatures he always considered too big a waste of his time to read about. How will he survive, having only his strong instincts to survive and a power that is nurtured from killing these beasts and taking their cores
