There are five elements and five spirits in the world, which take over the creation of the heaven and earth, and counteract the yin and yang of the Tao, which can lead mortals to the path of immortality.
Lin Han had false spiritual roots and lacked fire in his five elements. He had no chance of immortality until the fire spirit monster appeared and used himself as fuel to ignite his incomplete fire spiritual roots.
The road to immortality is long, and he kills all the demons and monsters; in the eternal loneliness, he kills all the heavens and the world.
If the immortals block the way, they will slaughter all the gods and Buddhas in the sky; if the demons block the way, they will kill all the eight evil spirits.
