At the foot of the Kunlun Ruins, Han Yitao was nailed to the Immortal Punishment Pillar. His spiritual roots were all shattered and his Dantian was completely destroyed. He was slandered as a "devil fetus" by the Lingxiao Immortal Sect because he had "chaos energy". When he was about to die, the remnant soul of Pangu that was sleeping in his body awakened, his broken Dantian turned into the "Hongmeng Chaos Dantian", and his incomplete spiritual roots transformed into the "Open Heaven Spiritual Roots". From then on, the good-for-nothing young man stepped through the sky and pointed his sword at the divine world - he held the "Chaos Opening Sky Sword" and drew the Nine Heavens Divine Thunder; he took the "Ancient Monkey" to understand the mystery and accompanied the "Dragon Girl" Peng Sha;
He gradually discovers that his own bloodline hides the ultimate secret of Pangu's founding of the world, and the life experience of his beloved Peng Sha is actually closely related to the conspiracy of "the destruction of the ancient gods in the divine world". When the Lingxiao Immortal Sect's pursuit, the Fallen Angel's scheme, and the catastrophes of the three realms followed one after another, Han Yitao used his mortal body to fight against the divine realm, vowing to break the shackles of the divine realm, restart the order of the three realms, uncover the "mystery of the fall of the gods" that had been sealed for millions of years, and finally become the "Chaos Emperor" to protect his loved ones and the common people.
