The Dao Fetus Heart Demon Scripture—a supreme demonic scripture of Eternal Night, an unparalleled demonic cultivation technique of immeasurable power. Once fully mastered, it can condense a demonic seed, called the Heart Demon Dao Seed, which silently attaches to a target. Hidden within, it absorbs all the host's chaotic thoughts and emotions, growing stronger with each passing moment.
This parasitic process is extremely subtle; even if detected, the host would only think it was a naturally arising heart demon within themselves. The heart demon and its host exist as two sides of the same coin. Once parasitized, escape is nearly impossible. When the heart demon manifests, the host's consciousness falls into dormancy. When the host awakens, the heart demon retreats—like day and night, alternating without ever truly meeting.
It could be likened to the split personalities of a schizophrenic.
The Dao Fetus Heart Demon Scripture can generate countless demonic seeds, parasitizing millions of lives. Silently, it can convert the host into a vessel of the demon's will, ultimately refining them into an external incarnation. Even if the original cultivator perishes, the demonic seed can facilitate rebirth.
Cultivation of this scripture is extremely difficult. Without unique traits or providential opportunities, success is nearly impossible. But once mastered, one becomes nearly indestructible. Not only are the demonic seeds extensions of the cultivator, but the cultivator's will also resides within them. As long as life exists, the heart demon persists. Even if the original body falls, it can return at any time.
It is similar in principle to Ming He : as long as the blood sea does not dry, the river never dies. Killing the cultivator is as difficult as ascending to the heavens.
The Dragon-Slaying Demon Lord, or rather Dragon-Slaying Demoness, had cultivated this supreme technique. This time, she did not personally enter Great Yi's Immortal Court. With Great Yi's heavenly laws already perfected, the entire realm under observation, and the Star Network constantly monitoring, even a momentary lapse could expose her. To remain unnoticed within Great Yi's territory was nearly impossible.
Her method was simple. Before Great Yi expanded, she located a realm and secretly implanted a demonic seed into an extraordinarily beautiful woman, silently linking the demon seed with her flesh and soul. The target remained completely unaware.
Yu Tingjun was only one of many she had prepared. Casting a wide net, the Dragon-Slaying Demoness skillfully waited for the right moment to strike.
Her patience was part of her technique. To ensure her pawn could enter Great Yi safely, she even provided covert protection for all the women implanted with demonic seeds, preventing accidents. Many would have perished before Great Yi's expansion if not for her interference. Once they entered Great Yi, she remained dormant, never manipulating their lives further.
Now, the time to reap the harvest had arrived. After years of waiting, she only needed one thing from Yi Tianxing: a strand of hair, or even a drop of blood.
Obtaining hair from someone at Yi Tianxing's level was nearly impossible. Every strand was like a divine weapon. His hair had opened a life meridian, condensed into a Red Dust Hair, and even gods' weapons could not sever it. The only feasible chance was through his bedside companion, Yu Tingjun.
Seizing this opportunity, the Dragon-Slaying Demoness carefully cut a strand of hair and transmitted it through a specialized technique.
"No escape, Yi Tianxing. This time, you are finished."
Looking at the hair in her hand, a glint of coldness flashed in her eyes. She could not be sure if Yi Tianxing had sensed her move, or what consequences might befall Yu Tingjun, but it no longer mattered. Even if Yu Tingjun died, it was only the loss of a demonic seed vessel. The ultimate goal had already been achieved.
From her hand, a palm-sized straw doll suddenly appeared. The straw was no ordinary kind—it was Hundred Witherings Thousand Tribulations Grass, said to mature only after hundreds of cycles of decay and thousands of tribulations. Each strand could rival a divine weapon, used for divination, crafting treasures, or forging celestial armor. The doll was made from ninety-nine strands, lifelike and exquisite—a perfect piece of art.
"Go!"
She pointed the hair at the doll. Instantly, the strand became a stream of light, merging perfectly into the straw body without flaw.
In the next moment, the featureless doll transformed, grotesquely yet lifelike, into a miniature version of Yi Tianxing.
"Yi Tianxing, you have risen from obscurity, ruling dozens of realms and billions of citizens, allowing them to live in peace. But to slay a true dragon, my Soul-Slaying Dragon-Slaying Needle targets the real dragon. Your bounty was far too high," the Dragon-Slaying Demoness sneered at the doll.
With a wave of her hand, she placed it on the altar, which had already been prepared.
The Soul-Slaying Dragon-Slaying Needle ritual: a straw doll made from Hundred Witherings Thousand Tribulations Grass, inscribed with the enemy's name, ten lamps on the altar, sacred footwork, inscriptions, and burning rituals. Three daily offerings. Each day, a Dragon-Slaying Needle would be thrust in, destroying three souls and seven spirits.
Slaying a dragon generates immense karma. First, honor the dragon to dispel karma; then slay it.
Though the Dragon-Slaying Demoness feared not the karma, the procedure still benefitted her.
Standing at the altar as the sun rose, she solemnly bowed to the Yi Tianxing doll with complete sincerity.
As she rose, a purple needle appeared in her hand. Its appearance alone radiated grandeur and legitimacy.
But it was far more than it seemed. The needle was forged from the residual resentment of fallen true dragons, combined with Reverse Scale Stone, tribulation energy, and thousands of auxiliary materials. Tempered in the endless abyss, refined in chaos—it was perfected only then.
A full set consisted of 365 needles, versatile, ever-changing, and devastating. In Eternal Night, even a demon god at the Dao-proving stage struck by this needle would instantly turn to ash. Its true lethality was hidden beneath an unassuming exterior.
Silently, a single Dragon-Slaying Needle pierced the Yi Tianxing doll. It disappeared into the body without a trace. The ten surrounding lamps flickered not once, showing no sign of disruption.
…
Back in the Great Yi Immortal Court, Yi Tianxing, having finished grooming, sat in the Royal Garden enjoying breakfast when an ominous premonition suddenly washed over him. His entire being felt an inexplicably bad sensation, almost like a sudden impulse.
Lifting his eyes toward the void, his gaze was profound, impossible to read.
"This has already begun? The Dragon-Slaying Demon Lord finally strikes. I've been waiting for you. The opportunity has been given—let's see if your demon is higher than my Dao. Reaching into my Immortal Palace… interesting indeed," Yi Tianxing thought, a flicker of awareness crossing his mind.
He had sensed it last night. The moment the hair was cut, he already knew
