In chaotic times, a peerless genius becomes a holy lord; in times of peace, a tyrant who brings disaster to the nation! Drunk, he lies on a beauty’s lap; awake, he holds the power of the world in his hands.

He possesses extraordinary martial skills, but in the real world, there is no place for them, so he can only be a shadowy assassin. Yet, upon arriving in a chaotic other world, on a battlefield of life and death, he can wield his weapons without restraint; here, to survive, can he, all alone, carve out his own domain? Can he claim for himself the most stunning beauties of all the noble families? Can he forge his own martial path and become the Supreme Spirit Emperor revered for all ages? He is a strongman, a tyrant, he is William Carter, and everything about him exists only in legend!
