On the day of the blood and bone sacrifice, Ji Xuanchen was stripped of his bones by his master to refine his blood. His immortal book was erased and he became a lonely soul in the netherworld. A hundred years later, he returned with the Bones of Defiance and the Nine Heavens Divine Blood, pointing directly at the heaven. Su Jin, the sword-wielder who had personally performed the ceremony, secretly used forbidden techniques to revive his remaining soul; while Xuan Yuanzi, the supreme leader of the Immortal Court, was using all living beings as fuel to ignite the fire of eternal calamity. When Lord White Bone revealed the ancient truth, Yun Wujiu's betrayal quietly took shape, and Qing Yan's memory was about to awaken - the Nine Heavens Immortal Book was not given by heaven, but forged in blood. This time, what they want is not to regain the immortal throne, but to burn all the laws of heaven.
