Tens of thousands of human skeletons were piled up in the valley and the corpse qi was already completely absorbed.
A white-robed young man stood in the middle of the large piles of skeletons. When he made a stomp on the ground, a thousand zhang* black mountain emerged out of nowhere.
Standing on the peak of the mountain, the young man's eyes sparkled with a mysterious light. He directly performed an archaic and abstruse formation seal. At first, the motion of his fingers were jerky but as he continued to practice, he grew more accustomed to it and the formation he created became more mellow and full.
With the cultivation towards the hand seals of the demonic techniques, the formation seals were not difficult for the young man to cultivate. After some practice, his fingertips moved up and down smoothly like a shadow.
