Agent of the Underworld

In this world, a sword immortal atop the northern snow mountains proves the Dao with his blade; demons lurking in the shadows wait for their chance to strike; countless monsters lie hidden in the desolate lands, withdrawn from the world; and the Spirit Sage Academy, whose students are found across the land, safeguards the books everyone yearns for. Then there is the old Taoist on Flowercloud Mountain, who loves meat so much that no one in the world dares claim to be his equal. He comes from the underworld, reforges his divine nature, commands the ghostly path, builds Youdu, battles the heavenly gods, and furiously throws open Heaven's Gate. With a single step, he ascends to immortality.
