After the divine war, the three realms were devastated.
The demonic nature buried in the body of Guanyin, the protector of the Heavenly Palace, quietly lost control. The power of devouring the gods eroded day and night, leading him step by step towards the abyss of eternal destruction. Tathagata, whose life span is about to expire in the heaven, does not hesitate to embark on a dangerous journey to find one of the four legendary elements - "the water that purifies the world".
Deep in the realm of Guixu, the evil beast Jiu Ying, who has been guarding for eternity, uses the illusion as a barrier and the inner demon as a blade, forcing the two of them to face their long-buried fears and obsessions. At the same time, Jiuyou, the ancestor of all demons who has been silent for thousands of years, is quietly breaking through the seal, with the goal of destroying the water that purifies the world and conquering the demonic murderous heart, pushing the three realms into a new round of turmoil.
The demon clan is surging, the dragon clan is awakening, and Asura is in civil strife.
No one can stay out of this storm.
Can the Tathagata pull his best friend back from the abyss of demonic nature before the five powers of deity and human beings are exhausted? And can that murderous heart standing on the ruins, looking down at the common people with scarlet eyes, be able to find that snow-white gown and the pride it once represented?
