At the peak of Jade Mountain, within the Heavenly King's Hall.
After hearing that the Four Heavenly Kings and the ghosts she had summoned were either exterminated or had dispersed, the Mother of the Mountain, a mountain deity, suddenly turned somber and murmured softly, "When will His Majesty return from the Netherworld with the Purgatory Fire? These people will reach the peak of Jade Mountain by tomorrow—I must reveal myself to stop them!"
No sooner had the Mother of the Mountain's words fallen than her body violently shuddered, her expression revealing extreme agony—she had received a warning from the curse of Heavenly King Mountain.
When she had accepted the role of the guardian deity of Heavenly King Mountain, she had made two vows to the mountain spirit: one was to never step off Heavenly King Mountain, and the other was to never harm humans. Otherwise, she was willing to accept any punishment from the mountain spirit.
