At the bottom of the Obliteration River, past memories flow like water, quietly traversing the riverbed...
The starry sky was that of the Northern Heaven Immortal World, and the location was the main sect star of the Black Demon Sect - the Yin Yang Star.
One day, above the Yin Yang Star, a spatial rift suddenly tore open, and a bloodied, ragged black-robed elder fell from the sky, crashing right into the Demon River beneath the Black Demon Mountain of the Yin Yang Star.
The disheveled elder who fell from the sky was none other than Wu Laoba, who had been treasure hunting in secret places. However, due to various mishaps, he was severely injured, and his mana was sealed. After falling into the Demon River, he couldn't even hold his breath, nearly drowning.
At that moment, a fierce-looking youth in black was meditating on the riverbank. Just as Wu Laoba was about to drown, it was this black-clad youth who fished him out of the river.
