Covering the Sky: Starting from a Piece of Grass and Killing the Sun, Moon and Stars

Traveling through the sky, he became an ordinary spiritual grass of heaven and earth. At the beginning, he obtained the inheritance of the nine-leaf sword grass, one of the ten evil spirits in the ancient immortal era. He practiced hard in secret in the Immortal Transformation Pond, and finally became a demon emperor. This is the immortality of a demon, this is the era when a grass cuts down the sun, moon and stars. Some people say that he is the incarnation of the elixir of immortality, some say that he is the reincarnation of the great emperor, and some say that he is a peerless monster that spans the ages. In his era, even the current emperors had to avoid his edge.
