The present-day Imperial Sanctum blurred. The gold-leafed walls and the waxy, dead Emperor dissolved into a smear of grey.
As Mo Ran's shadow loomed over him in the present, Li Wei's consciousness was violently yanked back into the dark abyss of his cellular memory.
He was no longer the eighteen-year-old Sovereign.
He was nine.
He was strapped to a vertical obsidian slab in the deepest sub-level of the Void-Pit. The air here didn't just freeze; it burned. It carried the sharp, ozone scent of raw Qi-conduits and the cloying, metallic tang of unwashed blood.
"The human nervous system is a masterpiece of inefficiency," Mo Ran's voice echoed against the damp, weeping stone walls.
Mo Ran stood before him, bathed in the sickly green light of a soul-lamp. In his hands, he held a spool of **Celestial Silk**. It wasn't cloth. It was a semi-sentient filament harvested from the cocoons of Void-Spiders that fed on the marrow of fallen cultivators.
The silk didn't just sit there; it vibrated with a faint, predatory hum that Li Wei could feel in his own teeth.
"To kill a God, your reactions must bypass the biological delay of the brain's processing," Mo Ran explained. His cold, callous fingers traced the line of Li Wei's **Ulnar Nerve** from the elbow down to the wrist. "Your flesh is a bottleneck. We must replace the copper of your humanity with the gold of the Void."
Mo Ran didn't believe in anesthetics. He believed that pain was the best "solder" for spiritual grafts. It ensured the body never forgot the price of its power.
He made the first incision at the base of Li Wei's left wrist.
The boy's **Nociceptors**—the pain-sensing neurons—fired a frantic, screeching alarm to his brain. But he couldn't even let out a gasp. Mo Ran had already placed a silver needle in his **Glossopharyngeal Nerve**, paralyzing his vocal cords.
Li Wei's mouth was open in a silent scream, his eyes bulging as he watched his own skin part.
The **Flexor Carpi Ulnaris** muscle was exposed, a raw, pulsing pink against the grey obsidian. It twitched rhythmically—a state of traumatic shock.
Mo Ran took a single strand of the Celestial Silk. With a needle thinner than a human hair, he began to 'stitch' the silk directly into the nerve bundle.
The agony was not sharp. Sharp would have been a mercy.
It was total. It felt like liquid fire being injected into his veins, turning his very blood into molten lead.
Every time the silk needle touched a nerve fiber, Li Wei's body underwent **Tetanic Contractions**. His muscles tightened so hard he felt his own tendons pulling away from the bone.
His spine arched so violently against the obsidian slab that the sound of his vertebrae grinding—*click, pop, crack*—filled the chamber.
"Focus, Li Wei," Mo Ran whispered. His face was inches from the boy's, his breath smelling of bitter herbs and death. "Do not let the pain drown you. Map the path of the silk. If your mind loses the thread, the silk will turn into a parasite and consume your marrow. You must *become* the weave."
Hours bled into days. Or perhaps it was weeks. In the darkness of the Pit, time was just another variable to be dissected and discarded.
Mo Ran moved with the tireless precision of a demon. From the wrists, he worked upward to the elbows, then to the **Brachial Plexus** in the shoulders.
Every inch of progress was marked by a new kind of torture.
When the silk reached the shoulders, Li Wei felt his sense of 'Self' beginning to fracture. To survive the intensity of the sensory overload, his brain did the only thing it could: it began to disconnect.
His **Prefrontal Cortex**—the seat of human emotion, of the boy who loved his sister—began to dim.
It was a biological defense mechanism. To endure the pain of being rewired, he had to stop being 'Li Wei'. He had to become a spectator of his own trauma.
He began to look at his own arm not as a limb, but as a series of **Levers** and **Pulley Systems**. He watched Mo Ran's work with a detached, clinical curiosity.
*Internal Log (Year 2):* The Silk has successfully integrated with the **Median Nerve**. Conductivity has increased by 400%. The sensation of 'Cold' is no longer felt as discomfort. It is now just a thermal data point—Value: 0.04 Kelvin above freezing.
"You are learning," Mo Ran observed, his voice devoid of praise, only acknowledging a successful experiment. He noticed the stillness in the boy's eyes. The frantic terror had been replaced by a cold, glassy void.
"The 'Boy' is finally dying. The 'Surgeon' is being born."
The procedure culminated at the **Atlas Vertebra**—the very top of the spine, where the body meets the brain. This was the most dangerous part. One millimeter of error, and Li Wei would become a vegetable.
Mo Ran held the final strand of Silk. This one was different. It was darker, infused with the refined essence of a thousand harvested souls.
"This is the Master-String," Mo Ran said, his eyes gleaming with a mad brilliance. "It will link your nervous system directly to the Void. It will allow you to feel the meridians of others as if they were your own. But it requires a final sacrifice."
He drove the silk into the **Foramen Magnum**, the narrow opening at the base of the skull.
Li Wei's world exploded.
It wasn't darkness. It was a blinding, white void.
Every memory of his sister's laughter... the smell of the morning soup... the warmth of a hand on his head... it was all incinerated. The Silk didn't just replace his nerves; it cauterized his soul's connection to his body.
He was now a puppet of his own design, a living loom of Celestial threads, bound to the man who had broken him.
Li Wei's consciousness snapped back to the Imperial Sanctum.
He was standing before Mo Ran. The "Master" who had spent years stitching agony into his bones.
His **Anatomical Sovereign** domain was now pulsing with a different frequency—the frequency of the Silk. He could feel the threads under his skin, humming in recognition of their creator.
Mo Ran reached out, his hand hovering near Li Wei's neck—the exact spot where the 'Master-String' was anchored.
"You remember the Silk, don't you, my boy? You know that with one thought, I can turn your own nerves into a cage that will crush your heart into pulp."
Li Wei didn't flinch. He didn't blink. His **Heart Rate** remained a steady, mechanical 55 BPM.
"I remember the pain, Master," Li Wei said. His voice was as flat and cold as the obsidian slab. "But I also remember the lesson you gave me during the third year."
He looked at Mo Ran's chest. His vision bypassed the white robes, the skin, and the muscle, focusing on the **Left Atrium**. There, that tiny, persistent arrhythmia flickered like a dying candle.
"You taught me that a surgeon must be a god. And a god does not weep for the clay."
Li Wei's fingers twitched—a movement so fast the human eye couldn't track it. A single thread of invisible Celestial Silk vibrated in the air between them.
"When you replaced my nerves with Silk... you gave me the ability to feel *your* pulse through the very air you breathe. You aren't my master anymore, Mo Ran. You're just a patient with a failing heart."
**Target Count: 3,000.**
**Celestial Silk Integration: 100%.**
**Current Objective: Survive the Master's Control.**
**[ Mo Ran tries to trigger the "Kill-Switch" in the Silk, but Li Wei has already used his Anatomical Sovereign domain to 're-route' the signal. Instead of Li Wei's heart stopping, Mo Ran feels a sharp, sudden stab in his own chest. The autopsy has begun.]**
