Undying War Emperor

Once a peerless genius, he was betrayed by a friend and accidentally swallowed the blood essence of an evil demon, then sealed away for a thousand years. When he unexpectedly broke free, the world had changed beyond recognition. His enemy was still alive and had become a god. How could he let him live in comfort? He raised the Blade of Time and unleashed a killing spree that turned heaven and earth upside down, determined to drag his enemy from the divine altar.
