"Serene Sword Observation." This cultivation method, imparted to An Jing by a mysterious voice, is a form of contemplation.
This contemplation allows An Jing to visualize a rusted sword within his mind, brushing it with his thoughts, subduing it with his heart, and polishing it with his resolve. Ultimately, one can cultivate a serene, translucent sword heart, capable of taming the "heart-monkey" and bridling the "thought-horse," thereby attaining freedom.
It is also a method for spiritual cultivation, capable of strengthening one’s mental intent and suppressing the psychological influence brought about by the "Emperor of Heaven Spirit-Piercing One Qi-Nurturing Method."
