In the Nine-Story Sealed Demon Cave, I Am the Only One Who Dominates

After a hundred years of spiritual energy resurgence, the human race on the surface has been involved in martial arts, and the alien seals in the underground are dormant and encroaching on the world. The young man at the bottom, who has the ancient blood of the human race and is dubbed the born waste blood, awakens the demon-devouring martial arts line, practices martial arts, destroys alien races, breaks down family barriers, and takes charge of the human realm. From an ant waste, he reaches the top of the world's martial arts.
