Taking "causal reincarnation" as the underlying logic, a fateful confrontation system spanning nine reincarnations is constructed. The protagonist retains some memory fragments in each reincarnation. Through nine reincarnations, he gradually reveals the truth about the chess game of heaven and earth, and finally completes the subversion and reconstruction of the rules of heaven in the ninth life.
The protagonist Yun Jiuyou experiences the nine realms of heaven:
1. Mortal Realm (Human World): The realm of mortals and the sect of cultivating immortals coexist
2. Netherworld (Yellow Spring): the mysterious force that controls reincarnation
3. Xuantian Realm (Immortal Realm): The Holy Land of Immortal Cultivation ruled by the Righteous Alliance
4. Demonic Abyss Realm: The Exiled Demonic Ancestral Land
5. Demon God Realm: The last refuge of the ancient demon clan
6. World of Weapons and Spirits: an independent world formed by the channeling of magic weapons
7. Fu Dao Realm: a special dimension that uses talismans to construct rules
8. The Realm of Inner Demons: The dark realm where the inner demons of monks are embodied.
9. Heavenly Realm (Place of Ending): The supreme existence that controls the laws of the heavens
In the end, the monks need to go through the "five declines of heaven and man" to break through the realm (the process of physical body decay/spirit tearing/Tao heart collapse/luck severance/karma backlash)
