The destruction of the Heavenly Deity Mountain caused a huge commotion in the Supreme Ancient Immortal Realms. No one expected that the letter sent by the Ziwei Divine Court would actually bring about such a terrifying ending.
In the Mystic Region, the three hegemonic powers which were the Ziwei Divine Court, Great Devil Divine Palace and Heavenly Deity Mountain have all existed for countless years, balancing each other out. Although the strength of the Heavenly Deity Mountain was slightly weaker, they were still a hegemonic power and had some foundations. None of the three powers dared to truly invoke a destructive war against each other. After all, from the perspectives of everyone, even if the Ziwei Divine Court could win against the Heavenly Deity Mountain, they wouldn't be able to avoid losing heavenly deities and would surely suffer casualties.
