(? Heroine + Genius)
Grandpa said that the sword to slay demons should be sharp enough, and the palm to suppress the underworld should be heavy enough - but he did not say that those half-human, half-underworld "monsters" were once heroes who guarded the world.
Xiaowu, a young man from a border town, clutched the broken gun left behind by his grandfather on a night when the underworld demon was chewing on the door panel. He thought that cultivating immortality was for revenge, but after stepping into the Great Wall of Jueming, he discovered:
The so-called underworld demons are monks who have gone crazy; the so-called taboos are the method of "controlling the underworld with the underworld" that the sages exchanged their lives for; and behind the seal that isolates the eight wastelands, Xing Tian's roar is shaking the world.
When the five arts of immortality encounter the strangeness of the underworld, when the boundaries between justice and alienation are blurred——
"What I am cultivating is not immortality, nor the underworld, but the way to protect these nine states from falling!"
