Three thousand years ago, the unknown sword master created the Qingyun Sword Way to suppress the Demonic Abyss, but was betrayed by his leader. He died and his sword tomb fell into silence.
Three thousand years later, he opened his eyes and became Lu Ren, the "Abandoned Vein" of Qingyun Sect Nanyuan - he woke up hungry in a leaky shabby house, was blackmailed by bullies, and even spiders despised his poverty.
The swordsmanship of the sect has been reduced to a fancy show, the sword tomb has been forgotten as a forbidden place, and the former disciples and descendants have become useless and chess pieces.
