The Eldest Senior Brother is a Mortal, Yet Extremely Powerful

Our Eldest Senior Brother is incredibly strong. He has slain the Jade Emperor, taught Sun Wukong a lesson, and once flew into a rage for the sake of his beloved, wiping out a hundred thousand celestial soldiers in a single night. His three-foot sword's edge once made all the gods and demons tremble in fear.But who would have thought that such a mighty Eldest Senior Brother was merely a mortal who had never cultivated immortality?
