The protagonist, Lin Chen Qingyun, was wronged and fell into the abyss, awakened to swallow the heaven, and settled old grudges; he traveled across the Central Plains, traveled through secret realms, and fought against the encirclement and suppression of the righteous way; he went to the wilderness, practiced hard for thousands of years, killed all the way, overcame tribulations, reached the top of the mortal world, and glimpsed the secrets of the heavens.
