Background

The Holy Demon Embryo is a special lifeform created by Heaven-Abandoning Emperor, the “God of Destruction and Rebirth” from the Pili world. It awakens in Chen Wu immediately after his transmigration. 3

Its constitution transforms Chen Wu's weak body into one capable of instinctively devouring primordial energy from heaven and earth. This allows him to bypass the usual dependence on exhausting vitality, blood, and medicinal resources when condensing true essence. 4 5

Chen Wu deliberately conceals the physique. After Gu Yuyue observes his ability to absorb spiritual energy directly, he allows her to identify it as the publicly known Heavenly Spirit Sacred Body rather than reveal the Holy Demon Embryo's true nature. 22 28

Manifestations

The Holy Demon Embryo has no separate fixed appearance as a physique, but it can manifest Chen Wu's second body, Zhu Wu.

• Zhu Wu — a red-haired body identical in appearance to Chen Wu; he identifies himself theatrically as “Silver Sovereign Zhu Wu.” 3 6
• Three souls — equivalent to three Primordial Spirits; they may eventually manifest as avatars. 3
• Linked consciousness — Chen Wu and Zhu Wu can understand each other's intentions without speaking. 7

Abilities & Skills

Twin Bodies

The Holy Demon Embryo grants its bearer two bodies that can act separately or together.

• Both bodies can fight simultaneously, increasing combat power and survivability. 3
• The bearer may change the main combat body during battle. 3
• Injuries can be transferred to the other body, allowing the uninjured body to continue fighting. 3
• Cultivation and strength can be transmitted between the two bodies regardless of distance. 3 17
• After Chen Wu detonates his main body's fifth-turn source seed, he draws on Zhu Wu's cultivation rather than losing his fighting ability entirely. 17

Three Souls

The physique's three souls provide exceptional perception, analysis, and spiritual potential.

• They are equivalent to three Primordial Spirits and can eventually manifest as avatars. 3
• They enhance soul perception, enabling Chen Wu to sense primordial energy and deduce cultivation methods with ease. 4
• They conduct uninterrupted simulated deduction of martial arts, alchemy, and other technical skills. 9
• They warn Chen Wu of cultivation danger, including when his body cannot yet bear a seventh-transformation breakthrough. 37
• Their empowered divine soul allows Chen Wu to successfully form the Dao-Demon Battle Diagram on his first attempt. 37

Self-Recovery

The Holy Demon Embryo is described as a nearly perfect immortal body with extreme regenerative ability.

• Its bearer cannot commit suicide. 3
• So long as a single breath remains, injuries can be healed completely in a very short time. 3 10
• It continuously absorbs qi to nourish Chen Wu's body, including while he sleeps. 5
• Zhu Wu's broken hand bones rapidly heal during his fight against River-Crossing Flood Dragon. 31
• This recovery, combined with Zhu Wu's repeated returns to battle, earns him the underground-arena title “Undying Vermilion Emperor.” 34 49

Dual Qi Flow

An innate martial art derived from Reverse-Returning Demon Origin.

• Absorbs the qi of heaven and earth, providing an effectively inexhaustible supply of true qi. 3
• Allows two moves to be used simultaneously. 3
• Provides resistance against attacks. 3
• Automatically circulates without Chen Wu's control, nourishing his body and accelerating cultivation. 3 5
• Enables the massive qi vortex used for Chen Wu's eighth-transformation breakthrough. 40

True-Absorbing Divine Formula

An innate martial art derived from Reverse-Returning Demon Origin.

• Converts energy contained in an opponent's attacks into Chen Wu's own true essence. 3
• Can absorb or release converted energy. 3
• Circulates autonomously alongside Dual Qi Flow to draw in heaven-and-earth qi. 3 5
• Assists in rapidly condensing and refining Chen Wu's Origin Seed. 18 19

Reverse-Returning Demon Origin

The supreme source art from which Dual Qi Flow and True-Absorbing Divine Formula originate.

• Reflects incoming true qi, protecting the user while harming the attacker. 3
• Replenishes inner essence from heaven-and-earth qi. 3
• Allows two moves to be unleashed at once. 3
• Chen Wu believes he may be able to recreate it after reaching the First Rank or higher. 4

Talent Enhancement

The Holy Demon Embryo enhances Chen Wu across martial cultivation and the Hundred Arts.

• Chen Wu learns the Trace-Hiding Step in less than a morning with the three souls' assistance. 8
• It supports concurrent cultivation in essence, qi, and spirit rather than forcing a single-path specialization. 7 10
• Chen Wu's sparring and the three souls' deductions lead to the creation of the physique-exclusive Sky-Piercing Strike. 19
• Sky-Piercing Strike can wield heaven-and-earth qi directly and combine freely with other moves. 19

Relationships

• Chen Wu — bearer and primary host; the Holy Demon Embryo awakens upon his transmigration and becomes the foundation of his cultivation path. 3 4
• Zhu Wu — Chen Wu's red-haired secondary body; shares a linked mind and can receive Chen Wu's strength and cultivation across any distance. 6 7 17
• Heaven-Abandoning Emperor — creator of the Holy Demon Embryo and originator of Reverse-Returning Demon Origin. 3
• Gu Yuyue — Chen Wu's adoptive older sister; believes his energy absorption stems from the Heavenly Spirit Sacred Body, which serves as cover for the Holy Demon Embryo. 28
• Undying Vermilion Emperor — title earned by Zhu Wu because his recovery and endurance make him appear impossible to defeat permanently. 34 49

Story Role / Major Arcs

Awakening and Foundation Building

The Holy Demon Embryo turns Chen Wu from a frail student who had barely sensed qi into a rapidly advancing cultivator. Its automatic energy absorption allows him to condense true essence and reach the fourth level of Essence Tempering in less than a day. 3 5

Dual-Body Training

Chen Wu manifests Zhu Wu at Zhiyuan Martial Arts School, assigning the secondary body to practice Eight Extremes Fist while he trains Primordial Palm. Their sparring accelerates both techniques to major mastery and later perfection. 6 7 19

Concealment and Reforging

After Chen Wu detonates his source seed to stop a Myriad Evils Cultist, the Holy Demon Embryo prevents his cultivation from being permanently ruined by supplying Zhu Wu's power. Chen Wu subsequently rebuilds a vastly stronger Origin Seed using the Profound Origin Art. 17 18 19

The Undying Vermilion Emperor

Zhu Wu uses the physique's inexhaustible qi, body-switching potential, and rapid recovery to survive brutal underground bouts. His repeated victories and apparent inability to remain injured create the legend of the Undying Vermilion Emperor. 31 34 49

Trivia

• The Holy Demon Embryo's two bodies and three souls make it especially suited to Chen Wu's decision to cultivate essence, qi, and spirit together. 7
• Chen Wu considers the Heavenly Spirit Sacred Body an ideal public explanation for only one fraction of the Holy Demon Embryo's abilities. 28
• Underground fighters speculate that the Undying Vermilion Emperor is either a shared identity, a lifespan-burning secret-art user, or a ferocious beast disguised as a human. 34
