The Invincible Domain of the Primordial World

Hu Shu transmigrates to the Primordial World at its highest level and becomes one of the first humans created by Nuwa. In his moment of desperation, he activates the Invincible Domain System. At first, the domain covers a three-thousand-li radius around Shouyang Mountain, the human race's homeland, and within it he is invincible.

The Lich Cataclysm erupts, putting the human race in mortal danger. The Chan School and other factions secretly obstruct humanity's development to protect their own interests, hoping to make humans sacrificial pawns in the cataclysm. Relying on his invincible domain, Hu Shu struggles to help humanity survive both the Witch-Slaying Sword calamity and the Lich Cataclysm. However, their conflicting positions make enemies of him among several factions.

During the era of the Three Sovereigns and Five Emperors, Hu Shu takes Fuxi, the Human Sovereign, as his disciple and helps him become a Sage of the Human Way. Hu Shu briefly merges with the Human Way himself, attaining power on par with the Heavenly, Earthly, and Human Ways. But in the process, he runs into numerous obstacles by threatening the interests of certain factions, and his own strength still proves inadequate against powerful opponents. After fulfilling his duties as Human Sovereign, he retreats behind the scenes.

During the Investiture of the Gods Cataclysm, Hu Shu places his invincible domain in Chaoge, extending it as far as the Four Rivers Pass. He takes Di Xin, Yang Jian, and Nezha as disciples and joins forces with Tongtian, the leader of the Jie School, to oppose the Chan School. The Sages try to use their superior power to interfere in the cataclysm, and Hu Shu and Tongtian do everything they can to stop them. In the process, Hu Shu must contend with the Chan School's open and covert schemes while managing complicated relationships with all sides. One misstep could cost him everything. He ultimately helps Di Xin survive the Investiture of the Gods Cataclysm, but leaves himself in an even more difficult position.

During the Journey to the West Cataclysm, Hu Shu sabotages Venerable Jianglong's tribulation and takes Yanzhi as his disciple. He also takes Wu Zetian as his disciple, helps her ascend to the throne as Human Sovereign and become a Sage of the Human Way, and unifies humanity.

As the Buddha-Demon Cataclysm approaches, factions everywhere are stirring, hoping to weaken
