1. Introduction: The Peak of Human Path

The Sovereign Immortal Fetus Gu is a Rank 9 consumable Human Path Gu. Its primary function is to transform a soul into the Sovereign Immortal Body, a vessel that bypasses the fundamental laws of the Gu World.

The “Heaven-Defying” Foundation

In a world where the Heavenly Dao enforces balance through conflicting Dao marks, this Gu allows for a “Sovereign” existence capable of cultivating all paths simultaneously.

Breaking Fate

By creating a body with “no parents and no origin” from the natural world, it transforms the user into a Complete Otherworldly Demon, making them entirely independent from the dictates of Fate Gu.

2. Origin: The Hundred-Thousand-Year Plan

This Gu was the obsession of Spectral Soul Demon Venerable, who spent 100,000 years within the Door of Life and Death researching the Legends of Ren Zu.

The Architect’s Vision

Spectral Soul realized that the Ten Extreme Physiques were fragments of the original human ancestor, Ren Zu. By recombining them, he theorized that a “perfect” human body could be recreated.

Shadow Sect’s Sacrifice

To fuel this single refinement, Spectral Soul exhausted the entire foundation of Shadow Sect and the Zombie Alliance, sacrificing countless Rank 8 materials, souls, and resources accumulated over millennia.

3. Refinement: The Ten Extreme Lifeless Formation

The refinement took place during the Battle of Yi Tian Mountain within the Ten Extreme Immortal Zombie Lifeless Formation.

The Materials

The core ingredients were the ten Extreme Physiques in their Immortal Zombie forms, including:

• Great Strength True Martial Physique
• Northern Dark Ice Soul Physique
• Other Extreme Physiques

The Process

These bodies were melted down to provide the unique Dao marks necessary for a non-conflicting structure. The final step required a Desolate Soul to inhabit the fetus and complete the life-birthing process.

4. Core Mechanic: Non-Conflicting Dao Marks

The defining “cheat” of the Sovereign Immortal Body is the perfect harmony between Dao marks.

100%–110%+ Efficiency

For ordinary immortals, possessing large quantities of one Dao path weakens opposing paths. For example, 10,000 Fire Path Dao marks would suppress Water Path methods.

However, Fang Yuan experiences no suppression whatsoever. Instead, his Dao marks amplify his abilities by 110% or more because there is no internal friction.

Killer Move Sequencing

He can activate complex multi-path killer moves instantly and seamlessly. A Strength Path move can empower a Sword Path strike while Time Path methods accelerate the attack, all without backlash.

5. The Sovereign Immortal Aperture: The Nine-Five Layout

The internal world created by the Sovereign Immortal Fetus Gu is the Nine-Five Sovereign Immortal Aperture, modeled after the world structure of the Immemorial Antiquity Era before seven of the original nine heavens were destroyed.

The aperture consists of:

• Five mini-regions on the ground layer
• Nine distinct heavens stacked above them

6. The Mini-Five Regions (Ground Layer)

Each mini-region reproduces the ecology and Dao mark environment of its corresponding region in the Gu World, allowing simultaneous cultivation of resources from every path and region.

7. The Mini-Nine Heavens (Sky Layers)

Above the five regions are nine colored layers of heaven. Unlike the ground layer, these heavens generally lack soil and are instead composed of atmospheric mists, floating ecosystems, and flying resources.

Mini Blue Heaven

Contains major star-related resources such as the Star Fragment Plain and Meteorite Pits.

Mini Red Heaven

Initially empty and frequently used as a battlefield or as storage for Year Beast communities.

Mini Green Heaven

The primary storage region for Dream Realms and Dream Path physiques.

Mini Purple Heaven

Home to enormous eagle nests, including the Upper Extreme Heavenly Eagle.

Mini Black Heaven

A dark, soul-rich environment filled with Walking Meat Trees and high-rank soul beasts.

Mini White Heaven

Managed by the Qi Sea Grotto-Heaven spirit and contains Cloud Cover Continent.

Other Heavens

Yellow, Orange, and Azure Heavens are primarily dedicated to specialized resource points such as Pill Azure Incense and Light Shine Fungus.

8. Scale and Expansion

At birth, the Sovereign Immortal Aperture possessed a total area of approximately 335,000 km², distributed as roughly 33,500 km² per layer.

However, the aperture is dynamic rather than fixed.

Through continuous aperture annexation, its total size eventually exceeded 33,500,000 km² — roughly one-quarter of Earth’s total land area.

This expansion is necessary not only for resource production, but also to satisfy the aperture’s hunger for additional Dao marks in order to maintain structural stability.

9. Extreme Time Flow

The aperture contains a gigantic Tributary of the River of Time, producing an extreme temporal ratio:

• 1 day outside = 60 days inside

This allows Fang Yuan to generate 16 beads of immortal essence every day, giving him one of the greatest economic advantages in the world.

10. Annexing Mechanics: Predatory Cultivation

Aperture Absorption

Fang Yuan can annex Blessed Lands and Grotto-Heavens of higher ranks without losing Dao marks, territory, or resources.

This completely bypasses the slow and restrictive progression of traditional cultivation.

Autonomous Management

He uses Land Spirits and Heavenly Spirits to govern annexed regions as semi-autonomous zones within the aperture itself.

One of the most important examples is the Lang Ya Land Spirit.

11. Regional Walls and Aura Adaptation

The Sovereign Body was designed to act as the “owner” of the entire world rather than belonging to a single region.

Ignoring Regional Walls

It can pass through Regional Walls without suppression or interference from chaotic regional Qi.

Aura Camouflage

The body automatically adapts its regional aura.

For example, when Fang Yuan enters Southern Border, his aura perfectly matches that of a native Southern Border Gu Immortal, rendering regional detection methods ineffective.

12. The Fatal Flaws: The Heaven Path Death Trap

Despite its overwhelming power, the Rank 9 Sovereign Immortal Fetus Gu remains incomplete and unstable.

The Hunger

The body behaves similarly to a Gu worm that requires feeding.

It must regularly annex Immortal Apertures of equal rank to stabilize itself. Without nourishment, the Sovereign Immortal Aperture will eventually collapse.

Lack of Dao Mark Defense

Because Dao marks do not conflict internally, they also fail to provide passive resistance against external attacks.

As a result, even lower-ranked attacks can become lethal if Fang Yuan lacks a dedicated defensive killer move.

Resource Bankruptcy

The aperture’s immense scale requires a terrifying quantity of resources to sustain its ecosystems, forcing Fang Yuan into constant expansion, warfare, and resource acquisition.

13. The Rank 10 Dream: Perfect Sovereign Gu

Spectral Soul’s ultimate ambition was not Rank 9, but Rank 10.

The Hunger Fix

A true Rank 10 Sovereign Body would likely no longer require aperture consumption because it would become a genuinely “Complete Human” rather than a hybrid existence.

Controllable Dao Conflict

Some theories suggest that Rank 10 would allow manual control over Dao mark interactions:

• Non-conflicting state for offense and cultivation
• Conflicting state for defense and resistance

This would eliminate the greatest weakness of the current Sovereign Body.

14. Strategic Importance: Foundation of the Great Love

The Sovereign Immortal Body is the foundation behind Fang Yuan’s rise into a being capable of resisting multiple Venerables simultaneously.

Its advantages include:

• Multi-path cultivation without suppression
• Massive immortal essence production
• Infinite resource expansion through annexation
• Freedom from Regional Walls and Fate
• Unmatched adaptability in combat

It transformed the title of “Otherworldly Demon” from a fearful label into a reality of absolute and nearly unchallengeable power.
