In the vast and mysterious world of prehistoric times, the witches and liches clash endlessly, devastating the world. Human leader Li Mu rises to prominence through his unique genetic cultivation system, forming an alliance with the witches to jointly confront the crisis. Human technology, with its two-dimensional foil sealing sages, stands out. Conscience-bound, Hou Tu, determined to relieve the suffering of all beings, resolutely transforms into a reincarnation. However, blessed by the merits of the Great Dao, she is reborn and transcends to the realm of sage. Later, Hou Tu establishes the Underworld within the depths of the Sea of Blood, constructing facilities such as the Six Paths of Reincarnation and the Eighteen Levels of Hell. The witches and humans work together to fill the Underworld. Li Mu, for aiding Hou Tu's reincarnation, earns the merits of the Great Dao and the authority of the Emperor of Fengdu, becoming the incarnation of his cellular will and ruling the Underworld. Reacting to this, the various factions begin a fierce battle for supremacy over the Underworld and prehistoric times...

Yang Hao traveled to the legendary prehistoric world and became the first human created by Nuwa. From the start, he awakened his divine powers and incredible understanding!

[You observed the entire process of Nuwa's creation, gained insights into the various great Daos, and created the Heaven-Covering Secret Realm cultivation method!]

[You witnessed Nuwa's enlightenment and assimilated the sage's Dao rhyme, comprehending the Immortal King-level cultivation method—the Creation Immortal Scripture!]

[You encountered a heavenly tribulation. Baptized by the thunder of the tribulation, you grasped some of the true meaning of the Great Dao of Thunder and suddenly realized the magical power of the Thunder Emperor!]

...

[You discovered flaws in the Heaven-Covering Secret Realm method, gained a glimpse into the endless starry sky, and created the Devouring Method!]

[Believing that learning from others' experience can polish jade, you comprehended the Immortal Dao and created the method of eternal life!]

...

Countless years later, Daoist Ancestor Hongjun, observing the three thousand great Dao laws swirling around Yang Hao, was bewildered: "No, each of the three thousand great Daos can lead to enlightenment. I was just saying it. Why are you serious?"

After traveling through the ancient times, Li Yun became a soldier of the demon clan with no background, no backing, no followers, and no inheritance.

It happened to be the wedding of Emperor Jun, and because of the crow bloodline, he was involved in a game and awakened a god-level fate-changing system. It started by intercepting Emperor Jun's wedding night and changing the fate of the emperor's concubine Chang Xi!

[Ding! Successfully changed Chang Xi's fate, and received the Complete Law of Fire as a reward!]

[Ding! Successfully changed the fate of the Golden Crow's birth and was rewarded with Chaos Fire!]

[Ding! Successfully changed Tongtian's fate and reward...]

[Ding! Reward for successfully changing Yuanshi's fate...]

[Ding! Reward for successfully changing my fate...]

As Li Yun continued to change the fate of the characters in the prehistoric world, obtained continuous rewards, and became stronger himself, the entire prehistoric world also underwent earth-shaking changes.
