Nether World

Biodata

Nature and Properties

• The Nether World exists in a different dimension from the Star Sea and does not rely on the Nine Provinces' Heavenly Fetal Earth Membrane. It may appear to overlap the Star Sea while remaining fundamentally separate from it. 367
• It is a true, vast world rather than a conventional secret realm. Yin Eyes and larger Yin-Nether Eyes connect it to the world of the living; the latter are described as “Ghost Gate Passes.” 385
• Yellow Springs Road leads from these gateways into the Nether World. Yin-Nether Eyes are widespread across the Star Sea rather than unique to the Nine Provinces. 385
• Entering physically exposes a living being to eventual consumption by Yin energy; entering as a soul normally causes cultivation to erode away until the intruder becomes food for necro-spirits. 385
• Yin energy suppresses the Heaven-Man Unity of Yang World Venerables while strengthening Ghost Venerables, making combat within yin-saturated territory heavily favorable to undead beings. 391
• Yin and yang are difficult to communicate across. Satellites can temporarily establish a network in the Nether World, but its Yin energy and Blood Moon corrode such devices within three to five days. 583

Environment

The Nether World's sky is eternally ink-black beneath a blood-red moon whose haze stains the landscape in dark red. Its terrain is dominated by black Nether Soil, gray clouds, bleak mountains, twisted vegetation, ghostfire, and wandering specters. 388

• Blood Moon — Illuminates the realm and creates an environment exceptionally favorable to practitioners of Nether World arts. 388 580
• Nether Soil — Black earth covering much of the first layer and used in structures such as Fengdu Ghost Capital. 388 622
• Yellow Springs Road — The route reached after crossing a Yin-Nether Eye; its waters are deadly. 385 388
• Forest of White Bones — A twisted bone forest visible in the first layer. 583 588
• Ghostfire — Oily green flames in which human faces can manifest with eerie laughter. 388
• Black Springs — Openings between layers of the Nether World that release purer Yin energy. 514

Layers and Regions

Inhabitants and Power Structure

Necro-spirits can be naturally born from the Nether World without reproduction. Many discard complex emotion and retain only primal urges to kill, devour, and grow stronger. 389

Major Factions

• Nether Soul Hall — A top sect of the Nether Death Domain headquartered in Nether Soul City. Its Black Death Platform secret realm refines low-level spirits into pure Yin energy. 390
• Dead Man Sect — One of the Nether Death Domain's major sects and a holder of Upper Ghost-level power. 391
• Styx Valley — Another major sect with an Upper Ghost and Ghost Venerable-level members. 391 398
• Bright Venerables — Ancient beings who promote the Underworld Manual and advanced Nether World methods to cultivate dependents and revive Nether World power. 579
• Yin Soldiers — Ancient military forces from the third layer, led in one major confrontation by Yuan Hong. 588

Relationship with the Yang World

In ancient times, the Nether Realm invaded the Nine Provinces and was driven back only after major sects and Grotto-Heaven Blessed Lands united. 367

When the Nether Realm opened again, black threads released from its gate drained the life force of living beings across the Capital. The Five Directions Grotto-Heaven Reverse Operation Array prevented an immediate full-scale invasion by redirecting its portals toward grotto-heavens and blessed lands, where Yin energy corrupted spiritual essence. 228 231

The Nether World's later strategy expanded beyond direct invasion. Ghost Immortal Queen Mother of the West and other forces spread cultivation methods among living beings, seeking to turn Yang World cultivators into Nether World immortals and bring them under Nether World control. 557 565

• World of the Living / Yang World — Its fundamental opposite; Nether creatures crave the blood, flesh, and souls of Yang World beings. 583
• Heavenly Court — Maintains frontier defenses and launched a punitive expedition into the Nether World under the protection of the Zhou Heaven Star Array. 586 587
• Nine Provinces — One of the worlds endangered by nearby Yin-Nether Eyes; its closest corresponding gateway is only one of four in its domain. 408
• Li Beichen — Entered the Nether World to investigate and restrain its threat, infiltrated its factions through his Yama Dharma Body, and later led Yang World forces through its layers. 386 390 588

• Nether Death Domain chaos — The World-Saving Necro-Scripture spreads across the domain, causing spirits to hunt one another for Necro-Spirit Essence and destabilizing the three major sects. 397 400
