The ruins of Lanshuo Temple (兰若寺) on Black Mountain (黑山) remain the most famous earthly site associated with Heishan Laoyao. Local legend says that on certain nights, the sound of a woman's weeping can still be heard from the temple grounds—though whether this is a remnant of Nie Xiaoqian's grief or the wind through the burned tree's roots is not known. A grove of dead locust trees grows at the mountain's base, their trunks blackened and twisted; folk tradition forbids cutting them for firewood, for to burn one is to wake the old resentment. The site has never been fully reclaimed by the living, and even today, travellers give the mountain a wide berth after dusk.

The narrative of Heishan Laoyao is closely interwoven with several other notable figures and locations. The female ghost Nie Xiaoqian was his most famous servant, forced to lure victims under threat of torment. The scholar Ning Caichen became his final target and unwitting catalyst for his destruction. The Daoist exorcist Yan Chixia was the primary instrument of the Ghost King's downfall, wielding a flying sword charged with pure Yang energy. The Underworld Judge (Pan Guan) Cui Jue provided the legal authority and the celestial thunder seal for the final assault. The domain itself—the abandoned Lanshuo Temple on Black Mountain—is a classic example of a Ghost Domain (Gui Yu), a bounded territory where Yin energy has concentrated to the point of semiautonomy. The story is also a cautionary tale about the limits of the Ghost King path: even supreme power in the ghost track cannot guarantee survival when Heavenly Tribulation and divine justice combine forces.

Heishan Laoyao is a Ghost King, the highest stable rank a Gui can achieve through mass absorption of other souls without undergoing the forbidden reversal into Ghost Immortal. His existence spans at least several centuries, likely longer than any mortal dynasty in the region. At this layer, a ghost no longer resembles a single person: it is a composite entity stitched together from thousands of absorbed souls, each one a voice, a wound, a memory. The Ghost King commands legions of lesser ghost-soldiers (阴兵) and can manifest a territory where Yin energy is so dense that it partially repels the pull of the Underworld and the corrosion of the Cosmic Gale. However, the price is constant internal turmoil: every absorbed soul continues to relive its own death within the King's consciousness. Heishan Laoyao is unusually stable for a Ghost King because his core is anchored to a physical object—the heartwood of a ten-thousand-year-old locust tree—which provides a fixed identity that most pure-ghost kings lack.

The death that produced Heishan Laoyao is not a simple human passing. According to the most widely circulated tradition, he was never a living man at all. In a prior existence, he served as a Zhen Mu Shou (镇墓兽) — a stone or clay funerary beast placed in an ancient tomb to ward off evil. Over centuries of exposure to the concentrated Yin energy seeping from the buried dead, the statue itself became infected with awareness, a kind of inverse animation. When the tomb was disturbed or the statue physically broke, its animating consciousness did not dissolve. Instead, it sought a new vessel: a giant locust tree whose roots had grown through a mass grave. The tree's heartwood absorbed the Zhen Mu Shou's residual will and, with it, the bitter resentment of thousands of unquiet souls trapped among its roots. This fusion of demonic artifact, plant life, and ghostly mass produced a being with no single moment of death—only a progressive transformation into something that had never been alive in the human sense. He has no memory of a mother's face, no recollection of the warmth of skin. His first awareness was the cold weight of grave soil and the sound of roots drinking sorrow.

From the moment of his formation, Heishan Laoyao did not need to find shelter—he was his own shelter. The locust tree grew on a Yin-rich slope of Black Mountain (黑山), a place where the dragon vein of the land had been poisoned by centuries of mass burial and failed exorcisms. The tree's roots penetrated deep into a stratum of concentrated ghostly residue, providing a natural fortress against the Cosmic Gale and the sun's Yang exposure during the day. Heishan Laoyao's initial survival did not depend on consuming other wandering souls; the tree's roots fed on the trapped ghosts beneath, and their Yin energy passively sustained him. But he quickly learned that passivity was weakness. To grow stronger and to project influence beyond his mountain, he began actively hunting. His method was indirect: he summoned female spirits—most famously the beautiful ghost Nie Xiaoqian (聂小倩)—and ordered them to seduce travelling men, drawing them into his domain where he could drain their vital Yang essence. This was not mere predation; it was intelligent cultivation. Living human energy, rich with Yang and life-force, could be converted into a form of Yin that accelerated his power far more than dead ghost-stuff ever could. Each victim added a layer to his composite soul, and each added a new set of memories—fragments of lives cut short by his hunger.

Unlike ordinary Li Gui (厉鬼), who become increasingly fragmented as they absorb other souls until they cannot distinguish self from other, Heishan Laoyao retained a remarkable coherence. The reason is structural: his core is not a memory-stream but a physical object—the heart of the locust tree. This core acts as a filter and anchor. When he absorbed a soul, the tree's heartwood extracted its Yin energy and its most potent obsession, then discarded the less useful personality fragments into the root mass, where they continued to suffer but no longer contaminated his conscious identity. Nevertheless, after centuries of absorption, his self was not entirely clean. The tree-heart stored the raw impressions of all his victims: a scholar's last sight of his wife's face, a merchant's terror of wolves, a soldier's final cry. These impressions did not become his memories, but they colored his perception. He saw the living world through a haze of borrowed pain and stolen beauty. He came to hate the living not because they had wronged him—he had never been alive—but because they possessed bodies capable of touch, taste, and warmth, while he could only experience those sensations through the echo of someone else's death.

By the time he entered the records of the living, Heishan Laoyao had accumulated an army of over ten thousand ghost-soldiers (阴兵), bound to him through partial absorption—they were not fully devoured, but controlled, their wills suppressed by his influence. His domain stretched across the mountain and the ruined Lanshuo Temple (兰若寺), a place that became synonymous with death for anyone foolish enough to stop there at night. He could not be killed by ordinary weapons; his true body was the tree's heartwood, hidden deep underground beneath layers of packed grave-earth and root. However, the Ghost King path offers one theoretical escape: the transformation into Ghost Immortal (Gui Xian). If a Ghost King can reverse the polarity of its Yin energy—generate a seed of pure Yang within its body—it can break free of the ghost state entirely and attain a form of deathless immortality. Heishan Laoyao attempted this ascent twice. Each time, his accumulated karma of murder was so heavy that the Heavenly Tribulation (Tian Jie) struck with intensified force. The first tribulation shattered a third of his ghost-soldiers and left him bedridden in his root-chamber for forty years. The second tore open the mountain itself, exposing his tree-heart to direct sunlight for three days. He survived only by drawing on the stored Yin of every soul he had ever absorbed, a bargain that cost him centuries of power. He never tried again.

The Underworld (You Ming Di Fu) was well aware of Heishan Laoyao's existence. His territory lay outside the normal jurisdiction of the Ten Yama Kings, but he interfered with the flow of souls—when he absorbed a living person, that soul did not go to the Underworld for judgment; it was consumed, denied its chance at reincarnation. This made him a cosmic lawbreaker of the highest order. On several occasions, teams of Gui Chai (soul escorts) led by Ox-Head and Horse-Face attempted to enter his domain to retrieve the stolen souls. They never succeeded. The Yin energy in his territory was so dense that the escorts could barely maintain their forms, and his ghost-soldiers outnumbered them. The Underworld's official position became one of strategic avoidance: as long as he remained contained to Black Mountain and did not expand his domain toward major population centers, the Celestial Decrees were not triggered. This changed when he set his sights on the scholar Ning Caichen, a mortal with an unusually pure spiritual constitution. Had he consumed Ning, Heishan Laoyao would have gained enough Yang essence to attempt a third tribulation with real hope. The scholar's resistance, aided by the Daoist swordsman Yan Chixia, turned the Underworld's passive observation into active intervention.

Heishan Laoyao's relationship with the other paths of existence is defined by predation and conflict. With the Daoist Immortal path, represented by Yan Chixia, he met his nemesis. Yan was a disciplined cultivator of the Sword Dao (剑道), a man whose flying sword carried the power of pure Yang lightning. Their first battle shattered the outer temple of Lanshuo and drove Heishan Laoyao back into his mountain refuge, heavily wounded. With the divine path (Shen Dao), the local City Gods (Cheng Huang) and Earth Gods (Tu Di) had long noted his presence but lacked the authority to confront him directly. The Underworld Judge (Pan Guan) Cui Jue eventually took the case and coordinated the final assault. With the Buddhist path (Fo Dao), there is no record of intervention; the temple at Lanshuo had long been abandoned and had lost its protective blessings. With mortals, Heishan Laoyao's method was systematic exploitation. He did not simply kill indiscriminately—to do so would attract attention from higher powers. Instead, he used his controlled spirits to lure selective victims, travellers who would not be missed quickly. The only mortal who escaped his web was Ning Caichen, whose integrity and the protection of Yan Chixia denied the Ghost King his greatest prize.

Heishan Laoyao's final state is total annihilation. After Yan Chixia and the Underworld Judge laid an inescapable formation—a net of Heaven and Earth (天罗地网) that sealed the Yin energy within the mountain—the judge used a Celestial Thunder Seal to ignite the heartwood of the locust tree from within. The thunder was pure Yang, the same force that had twice rejected his tribulation bids. This time there was no escape. The tree burned for seven days, each root a scream of released souls. When the fire died, nothing remained of Heishan Laoyao: no core, no ghost soldier, no lingering echo. His Zhen Ling (True Spirit)—if he had ever possessed one—was consumed entirely by the Yang thunder, a final negation of a being that had thrived on the stolen existence of others. He did not enter the Six Paths of Reincarnation. He did not become a hungry ghost in the margin of the world. He simply ceased. The mountain where he once ruled is now a scar of blackened stone, shunned by spirits and mortals alike.
