History

Within Zhou Heng's Dantian

The Black Sword had already been floating in Zhou Heng's dantian when he began cultivating at age eight. More than a foot long, entirely pitch-black, and broken, it diverted every strand of True Essence Power Zhou Heng cultivated into his dantian for nearly ten years. 1

When the sword began trembling violently, Zhou Heng endured overwhelming pain and suppressed it through force of will. In response, it transmitted the Nine Sword Styles into his mind; their diagrams later became known as the Heaven-Soaring Nine Styles. 2 4

Afterward, the sword ceased consuming Zhou Heng's True Essence Power and began releasing immense quantities of pure free energy at midnight. This energy allowed Zhou Heng to rapidly advance through the Body Refining Realm; its output increased after he entered the Flesh Refining stage. 3 5

At the Spirit Gathering Realm, the Black Sword first manifested outside Zhou Heng's body. It formed a blood-bound connection with him, could be summoned or returned to his dantian by thought, and proved capable of cutting the Frost Cold Sword into pieces with effortless contact. 50

Fragments and Origins

The sword has repeatedly sought out fragments of itself. It ignored Zhou Heng's control to pursue a fragment held within a celestial maiden, then fused with it and grew longer. 322 It later reacted to another fragment belonging to the Blood Moon Daughter and accepted it without resistance when she took hold of the blade. 780

Residual Sword Qi at a shattered Immortal Continent gate took the form of the sword's original, complete shape. This revealed that the Black Sword's past Sword Qi had severed the continent, while the sword itself had subsequently been broken. 348

Red Moon identifies the sword as the Void lineage's sacred artifact and calls it the Void Sword. Later accounts identify it as a supreme treasure of the Bright World and a Chaos-grade weapon once wielded by the Primordial Void Sage. 781 1014 1120

Appearance

The Black Sword is a broken longsword of absolute blackness, including its hilt. Despite its damaged form, it carries an ancient and world-shaking presence. 1

• Originally described as more than a foot long. 1
• Its broken blade is pitch-black and coldly lustrous when manifested. 352
• It grew one inch after fusing with its first known recovered fragment. 322
• Its Sword Qi manifests as violent black radiance and can resemble an ink-black dragon. 784

Disposition

Though ordinarily inert, the Black Sword displays recognizable pride, attachment, hunger, anger, and joy. It responds to Zhou Heng's will under normal conditions but is not completely obedient. 189 322 556

It reacted with fury when Blood Sword Heavenly Lord's demonic sword attempted to suppress it, destroying the larger sword and killing the Heavenly Lord. 215 It also showed strong closeness toward the celestial maiden carrying its fragment, Huotian, and Red Moon. 322 556 780

Abilities & Properties

Heaven-Soaring Nine Styles

The Black Sword transmitted nine profound sword diagrams directly into Zhou Heng's mind after he subdued it. The styles require no written formula; their understanding was integrated into his body. 2 3

• The sword and the Heaven-Soaring Nine Styles are described as inseparable. 50
• The styles can draw in surrounding spiritual energy when wielded through the Black Sword. 50
• Zhou Heng could initially unleash only the first seven styles before exhausting his strength. 50
• Their sword pressure can imitate and exceed dragon might; the sword itself can suppress a divine dragon. 118

Energy Release and Life Essence Absorption

The sword initially accumulated Zhou Heng's True Essence Power for a decade, then repaid that accumulation through nightly releases of exceptionally pure free energy. 1 3

• Its midnight energy could be directly refined into True Essence Power, drastically reducing cultivation time. 3 4
• After killing martial artists or demonic beasts, it absorbs their life essence and can release it for Zhou Heng's cultivation. 59 107
• The quality of its released energy depends on the slain target's cultivation. 59
• It can absorb and release high-realm power; after Zhou Heng killed an Earth-Splitting Realm cultivator, it released the captured power without retaining it for itself. 137

Indestructible Cutting Power

The Black Sword's defining combat property is its extreme sharpness and durability. It can cleave materials and weapons that ordinary artifacts cannot damage. 50 215

• It cut through the Frost Cold Sword with light taps. 50
• Han Yiyao used it to carve through a stone chamber built from Spirit Sea Realm-grade materials. 215
• When provoked by Blood Sword Heavenly Lord's demonic sword, it unleashed its own power and shattered the weapon into numerous pieces. 215
• It pierced an immortal body whose physique was comparable to a Spirit Transformation Dharma Artifact. 489
• A strike to a vital point is typically fatal; even a graze produces severe, difficult-to-heal bleeding. 527 718
• Its destructive force ultimately depends on the wielder's strength. 215
• Against true Chaos Realm experts, it can no longer guarantee a kill through its cutting power alone. 1014

Suppression and Negation

The sword can counter or destroy powers that resist conventional cultivation methods. 36 774

• It helped Zhou Heng resist the mind-clouding influence of a blood-colored stone stele and supplied power to revive Han Yulian. 36
• It suppressed the remaining power of the stele's blood-red light, allowing Zhou Heng to refine it. 37
• It destroyed the law fragment contained within sacred medicine, allowing Zhou Heng to absorb the medicine safely. 774
• Its connection to Zhou Heng shielded his divine sense from the celestial maiden's overwhelming aura. 322

Artifact Sense and Fragment Resonance

The Black Sword can detect valuable objects and guide Zhou Heng toward them, though it reacts selectively. 5 189

• It pointed toward a hidden treasure beneath a stone in the Heaven-Leveling Mountain Range. 5
• Zhou Heng compelled it to identify Ma Buqian's correct inheritance box after sustained pressure from his will. 189
• It independently pursues fragments of itself and may disregard Zhou Heng's orders while doing so. 322
• A trace of its Sword Qi on an unknown short blade allowed Zhou Heng to infer the presence of another fragment. 750

Bloodline Enhancement and Rune Integration

The sword gradually enhances Zhou Heng's Bloodline Power, with major cultivation breakthroughs producing especially significant gains. 118 137

• It improved Zhou Heng's Purple Fire, Metalization, and Azure Dragon Bloodline over time. 137
• It instantly destroyed the resistance within the Yellow Dragon Pill, allowing Zhou Heng to absorb the cyan dragon's power without personally enduring its dragon might. 118
• Zhou Heng later fused offensive minor runes into the sword to increase its combat power. 718
• It can channel the Five Elements Rune into black-and-gold Sword Qi for attacks against vastly stronger opponents. 818

Relationships

• Zhou Heng — Current master and primary wielder. The sword enabled his cultivation, supplied the Heaven-Soaring Nine Styles, and remains stored in his dantian, but it can refuse his commands when fragments are involved. 2 50 322 556
• Huotian — The sword circles her with intense attachment; Huotian responds with visible longing when she holds it, implying a connection to its past. 556
• Red Moon — Identifies it as the Void lineage's sacred artifact. The sword accepts her handling and joyfully fuses with her fragment. 781 780
• Peerless celestial maiden — Carried the first recovered fragment. The sword halted before harming her and showed closeness and hope toward her. 322
• Blood Sword Heavenly Lord — His demonic sword's suppressive aura provoked the Black Sword into revealing its might and destroying him. 215

Trivia

• The Black Sword's former complete Sword Qi was powerful enough to split an Immortal Continent. 348
• Black Donkey covets the sword but cannot wield it normally because it lacks hands; it proposed using its mouth instead. 221
• The sword has been mistaken for an ordinary broken weapon by enemies who underestimated its ability to pierce their defenses. 489
