History

Ancient Supremacy

During the Immortal King era, the Profound Yellow Great World was protected by the Primordial Chaos Daoist and the World Tree. The tree was a natural counter to the Divine Race: invading Divine Kings could be refined into Divine Ability Fruits, while Divine Emperors became Longevity Fruits. These fruits strengthened the world's defenders and helped secure its foremost position among the Three Thousand Great Worlds 427 462 463.

The World Tree connected the Immortal Realm above with the Profound Yellow Great World below, drawing upon both immortal vital energy and the world's earth energy. The Divine Race's Progenitor Holy King severed it despite the severe injury this cost him. Its destruction, followed by the disappearance of the Immortal Kings, ended the world's protected golden age 427 459 463.

Ancient Divine Race Calamity

A subsequent Divine Race invasion nearly annihilated the Immortal, Demon, and Monster paths. The Heaven Sovereign, Earth Sovereign, and Human Sovereign led the resistance, supported by the Nine Ancient Venerables and immortals descending from the Immortal Realm 427.

The defenders repelled the invasion, but the world was nearly shattered. All three Sovereigns died, and Pan Wu Immortal Venerable fell against seven Divine Emperors. Part of his surviving legacy became the Heavenly Martial Treasury, an inheritance later associated with Hua Tiandu 427.

Other traditions also disappeared. The Xuanming Sect was destroyed during the calamity; a mortally wounded survivor carried its supreme treasure into a hidden realm, where a remnant of his spiritual sense persisted 565.

Decline and Renewed Danger

The world's surviving factions compete for dispersed resources rather than operating under a unified authority. Compared with the Tianyuan Great World's dominant sect, this fragmentation limits the support available to individual powers. Realm King experts are also far less commonly encountered than in the Hongtai Great World 471 571.

Its ancient treasures nevertheless attract outsiders, including the Qingqiu fox tribe and Wuji Star Palace. Meanwhile, the world's Source has become restless, and rapidly advancing Sons of Destiny have begun to emerge ahead of another great tribulation 530 534 562.

Geography and Cosmology

Overall Structure

• Shape and scale: An immense, oval, egg-like world, far larger than any individual star, with countless folded and layered spaces inside it 448.
• Outer surroundings: Enveloped by infinite nebulae, each containing tens of billions of stars, living beings, and hidden void realms 448.
• Atmosphere: Surrounded by layers of gale-force atmosphere, including the Nine Heavens Gale Force layer separating it from outer space 514.
• Oceans: An ordinary cultivator can require years to cross a single ocean. Ancient experts once moved dozens of stars into the sea without filling even a corner 529.
• Sun and moon cycles: Hundreds of suns illuminate different regions. Thousands of suns and moons occupy a vast external space-time and emerge in regular day-and-night cycles through natural creation rather than human mana 537 583.
• Underground spaces: Numerous dimensions extend beneath the surface toward the legendary Nine Netherworld, where ancient dead and Ghost Gods born from the world's Source Power reside 565.

Factions and Society

Political Structure

The principal factions are grouped into Ten Immortal Sects, Seven Demonic Veins, and Five Demon Sects, alongside innumerable smaller sects and rogue cultivators. Underground demon-human forces also occupy extensive territories under three great Demon Emperors 433 471.

Cultivation and Commerce

• Unequal access to inheritance: Most rogue cultivators possess only minor divine abilities. Some who reach the Mana Realm remain trapped there for life because they lack subsequent teachings 421.
• Population cultivation: Taiyi Sect distributes White Sun Rice in the Great Xuan Empire, contributing to its citizens' high physical cultivation levels 440.
• Major merchant guilds: Heavenly Dao Pavilion, Six Paths Alliance, and Nine Tripod Pavilion issue pill-storage VIP crystal cards that also signify status 440.
• Talent rankings: The Immortality Candidate List measures prominent cultivators below the Longevity Realm. Fan Qingying formerly held first place before Lin Yu suppressed her 482.
• Competition for training resources: The Five Elements Land's inexhaustible spirit monsters make it a coveted cultivation resource. Chiyuan Demon Venerable argues that controlling it could enable a sect to become the world's strongest 446.

Source Power and Sacred Connections

World Tree

The World Tree, also called Jianmu, links the Immortal Realm's vital energy with the Profound Yellow Great World's earth energy. It is also the singular power capable of restraining the Earth Sovereign's Book 459.

• Refines Divine Race beings into fruits that advance cultivation 462.
• Historically supplied these fruits to defenders fighting the Divine Race 463.
• Survives through fragments that Lin Yu revives into a growing sapling 459 564.

• The projection is not invulnerable: Lin Yu destroys it with Profound Yellow lightning and captures Su Xiuyi's shattered clone 552.

Great Xuanhuang Technique

Lin Yu comprehends the Great Xuanhuang Technique while observing the world's form from outer space. Ranked among the foremost Three Thousand Great Daos, it concerns the foundations established after primordial chaos divided into heaven and earth 514.

• Makes its practitioner a favored child of the world's destiny 514.
• Grows stronger as the Profound Yellow Great World becomes more prosperous 514.
