Ch. 1801The Fourth Sword, Dugu Qingxiao's Nirvana Power
Dugu Qingxiao fought the Sword Fiend with his Black-and-White Endgame Sword Domain, but the Sword Fiend shattered the domain and destroyed his body and Primordial Spirit. Xu Taiping feared that his Second Senior Brother would have to use Nirvana Power after all.
- Zhao Qian warned Xu Taiping that Dugu Qingxiao had used Nirvana Power before the battle and that Xu had to stop him after his third use.
- Fairy Lingyue identified Dugu Qingxiao's sword art as the cursed Avīci Sword, which could drag its cultivators into the Yellow Springs and the Hungry Ghost Path.
- The Sword Fiend overwhelmed Dugu Qingxiao, who used his Primordial Spirit to wield his sword and repel one strike.
- Dugu Qingxiao formed his Black-and-White Endgame Sword Domain, turning both fighters' powers into stones on a Go board and challenging the Sword Fiend to play.
- The Sword Fiend summoned enormous flaming Sword Shadows that shattered Dugu Qingxiao's domain and cut off his head, causing his True Body and Primordial Spirit to explode.
