The Peerless Demon Emperor

They call him a demon, yet his sword dominates the heavens and his power shakes the universe, transcending even the immortals! They brand him a Buddha, yet he slaughters wherever he goes, mountains of corpses piled up and rivers of blood streaming, more demonic than demon itself! Cleansing his body with blood and tempering his bones with fire, in the cycle of life and death, he becomes a great demonic lord! The young Lin Feng rises above his hardships, unexpectedly acquiring the Demonic Seed, thus becoming the only Demonic Patriarch in this universe!
