Bound by a cultivation pact with the cold-faced peak master, the Ten Thousand Swords Formation shatters the traitorous evil cultivators. Dan Peak Master Su Yan feigns fragility to fake a fall and trap Sword Peak Master Xie Wuyang, forcing him to do chores at Dan Peak. Everyone thinks he is a delicate alchemist, but he is actually the young peak master who fell off a cliff and disappeared three hundred years ago, having once feigned allegiance to the Myriad Souls Ravine to secretly ruin half of its foundation. Elder Zhou colludes with evil cultivators to frame Dan Peak. The two forge a cultivation pact to investigate, their identities are exposed, and misunderstandings erupt. Finally, they join forces to destroy the banner, eliminate the evils, and clear out the traitors, resolving three hundred years of grievances and staying side by side.
