During the period when the Three Mountains were unity through marriage, the Three Mountains grew stronger together, their influence almost overshadowing the Two Palaces.
Unexpectedly, this future hope of Jun Mountain, the cherished son of the Three Mountains, perished shortly after his wedding at the hands of Dong Xiaoyan, a daughter of the Palace Master of Heavenly Sword Cloud Palace!
Upon confirming the news, the Three Mountains collectively erupted in fury, vowing to avenge their loss by wiping out Dong Xiaoyan!
The Three Mountains joined forces to surround Dong Xiaoyan, killing her two protectors and leaving her on the verge of death. Had they not decided to capture Dong Xiaoyan alive and execute her at Miao Jianhan's grave, she might have already been dead.
However, the tide changed with Dong Xiaoyan's battle pet, Ice Phoenix. Seeing its master in danger, it self-destructed in a last-ditch effort, giving Dong Xiaoyan a glimmer of hope.
