The shackles of heaven were broken, and the three realms were at peace for the first time. However, the embers of the prison cage were not yet cold, and they turned into chaotic clouds of calamity. As soon as the eternal demon god Sun Wukong broke free from the prison of heaven, he saw the remnant soul of the ancient evil demon "Chaos Ancestral Witch" emerging from the calamity cloud - it claimed that Wukong's act of breaking the shackles was actually the release of chaos, and now it would restart the era as a sacrifice to the Three Realms. What's even more dangerous is that the blood of the demon god in Wukong's body goes berserk due to the broken heavenly path. Sometimes he destroys the demon ape, and sometimes he wakes up and asks in pain: "Am I the savior or the source of calamity?"
Bajie carries the secret of the pure altar, Sha Monk holds a weak water hyacinth, and the white dragon horse appears as a swordsman in the sea. The former Buddhist monks gather together again to explore the sea of blood in the underworld and guard the Flower and Fruit Mountain. During the fierce battle, Wukong recalled the memory of the Sky-Building Stone Spirit in his previous life: He was originally a combination of chaos and order, and his destiny to balance the two worlds was hidden in his bones.
On the top of Buzhou Mountain, the Chaos Ancestral Witch used the Chaos Bell to control the three realms. Wukong melted the Sea God Needle, the Sky-Mending Stone, and the blood of the demon god to transform into the eternal demon god to fight. The ending is revealed: the so-called "Heavenly Way" is actually a testing ground for selecting a new order, and he is the chosen "variable". After defeating the evil demon, Wukong used his body as an anchor to seal chaos and reenter the reincarnation, leaving only an oath: "If the Three Realms are catastrophic again, come to the underworld to find me - I will always be the monkey who dares to pierce the sky."
Thousands of years later, the old monkey selling peach in Chang'an City had a rusty stick attached to his waist, and there were eternal galaxies hidden in his eyes. The embers are not yet exhausted, but the story of Qi Tian Demon God has just begun.
