Morning light filtered through the workshop windows, casting golden rays across heavy iron workbenches. Dust motes danced in the warm glow, the only movement in the otherwise silent room.
Lin Tian sat cross-legged on the cold stone floor. Eyes closed. Breathing slow and measured.
The faint scent of wild orchids still clung to his obsidian robes—a lingering trace of last night. He hadn’t claimed Aunt Lin’s body. But by curing her decade-old Qi Stagnation and lifting the heavy veil of depression from her heart, he had claimed something far more valuable. Her absolute, unwavering devotion.
Suddenly, a splitting sensation erupted deep within his brain. Liquid gold crashed into his neural field like a tidal wave. Lin Tian gritted his teeth, muscles trembling violently, as the familiar mechanical voice echoed in his mind.
[Ding! Target 2 (Aunt Lin) reached 100% Obsession. Conditions met. Upgrading System to Version 2.0...]
[Upgrade Complete. Welcome to Version 2.0, Host.]
Lin Tian opened his eyes. The holographic interface before him was laced with deep crimson runes radiating primordial authority.
[Reward Unlocked: Primordial Yin-Yang Imperial Sutra.]
Ancient knowledge flooded his mind. His stellar eyes widened. The sutra was a supreme dual-cultivation technique from a forgotten era.
"When I dual cultivate with a Yin woman," he murmured, "I absorb her energy to break bottlenecks. Refined Yang flows back. She grows with me."
He smiled slowly. "Madam Shen. Aunt Lin. They won’t just be followers. They’ll be powerhouses."
Another notification appeared.
[Warning: Host at Peak Qi Gathering Level 10. System advises against Foundation Establishment breakthrough.]
Lin Tian’s brows furrowed. "Why?"
[Ancient Qi Gathering had 13 Layers. Modern cultivators break at 10 due to thin spiritual energy.]
[13th Layer requires Extreme Dark Yin Energy as coolant. Pure Yang alone will combust meridians.]
"The 13th Layer..." Lin Tian whispered, his eyes blazing.
In this world, everyone believed Level 10 was the absolute limit. If he could reach the 13th Layer, his baseline power would be so massive that ordinary Foundation Establishment cultivators would look like fragile children.
"Madam Shen has Profound Yin-Spirit Body. Pure and icy. Aunt Lin has a hidden physique but definitely not a dark type with her stable and calm persanality." He rubbed his chin thoughtfully. "Neither has Dark Yin. I need a woman who walks in shadows."
He logged that thought into his mental database. The Inner Sect Tournament was approaching, but before he could conquer the Inner Sect or hunt for a Dark Yin host, he needed to address a glaring weakness in his arsenal.
Lin Tian stood and walked to his heavy iron workbench. Resting there was his modified wrist-crossbow. It was a masterpiece of mechanical optimization. He had utilized tension mechanics and kinetic transfer theories to maximize its lethality. But as he picked it up, a cold realization washed over him.
"Physical mechanics have gotten me this far," he muttered, running his thumb over the cold metal casing. "By optimizing the structure, I turned a low-grade weapon into a peak-grade killing machine."
He placed the crossbow down.
"But there’s a ceiling. A spring can only hold so much tension. Steel can only endure so much kinetic force. If I want to fight Core Formation Matriarchs, or eventually build massive flying swords and spiritual armors... I cannot rely solely on basic mechanics."
He needed to learn the esoterics of this world. High-level Rune Engraving. Array weaving. Advanced spiritual material smelting. He needed to fuse extreme structural precision with runic magic to become a true Master Artificer.
With his goal set, Lin Tian immediately went to work. He walked to a massive bookshelf in the corner of the workshop. Thanks to Madam Shen’s absolute control over the Resource Hall, she had secretly smuggled dozens of classified, high-level manuals from the Inner Sect archives into his restricted workshop.
Titles like The Fundamental Compendium of Runic Resonance, Advanced Array Weaving for Tier-2 Artifacts, and The Flow of Spiritual Fire lay stacked before him.
Lin Tian sat at his desk, lit a spiritual candle, and opened the first manual.
Because of his Level 10 Peak cultivation and his constantly evolving physical body, his brain operated at a terrifying speed. He read ten lines at a single glance. Pages flipped rapidly, rustling paper filling the quiet room.
He absorbed modern runic engraving theory like a sponge. In the Cultivation World, runes were the language used to command the universe’s energy. By carving specific symbols onto metal and injecting them with spiritual energy, one could alter the metal’s weight, heat, sharpness, or aerodynamic drag.
"The problem with modern refiners is their lack of absolute precision," Lin Tian said, closing a thick manual after twenty minutes of speed-reading. "They carve runes by hand using spiritual energy, but their hands shake. Their energy fluctuates. They make runes large to prevent short-circuiting. A standard flying sword can only hold about fifty to sixty runes before it runs out of surface area."
His lips curled into a confident smile.
"Precision is exactly my specialty. If I apply the concept of microscopic integration—layering patterns infinitesimally small like complex data circuits—I can bypass this limitation. Why carve one large rune when I can engrave a localized network of microscopic runes?"
He grabbed a blank piece of cold-iron no larger than a coin and clamped it securely into a vice on his workbench. He picked up a highly sensitive, diamond-tipped engraving stylus.
Closing his eyes, Lin Tian took a deep breath, channeling the newly acquired Primordial Yin-Yang Imperial Sutra. His golden Yang Qi flowed from his Dantian, down his shoulder, through his arm, and centralized into the stylus’s tip.
Unlike other cultivators whose spiritual energy leaked and fluctuated, Lin Tian’s extreme focus allowed him to compress his Qi into a microscopic, razor-sharp point.
He opened his eyes. Completely devoid of distraction. Sharp. Terrifyingly calm.
Scratch... scratch... scratch...
The stylus moved over the small coin-sized cold-iron. To the naked eye, it looked as if Lin Tian wasn’t doing anything at all. His finger movements were so infinitesimally small they were practically invisible. But under a magnifying lens, a miracle was taking place.
Instead of carving one large ’Wind-Piercing Rune’, he was carving a localized network of microscopic runes. He was packing hundreds of spiritual commands into a space where normally only one could fit.
Sweat beaded on his forehead. The mental processing power required for this extreme micro-engraving was astronomical. Every stroke had to be measured perfectly. If his spiritual energy spiked by even a fraction of a percent, the intricate channels would cross, and the entire iron piece would explode into lethal shrapnel.
One hour passed. Two hours.
Lin Tian sat as still as a statue, his breathing completely halted, relying entirely on internal Qi circulation to oxygenate his body. The only thing moving in the room was the microscopic tip of the stylus.
He merged raw physical control with spiritual energy. He wasn’t just carving; he was using the stylus’s microscopic vibrations to forge and compress the iron’s internal structure, ensuring the metal could handle the dense spiritual load.
Finally, after three grueling hours, Lin Tian forcefully pulled the stylus away.
Haaa...
He exhaled a long, heavy breath of white steam. His muscles, locked in absolute tension, relaxed. A wave of profound exhaustion washed over his mind.
But as he looked down at the coin-sized piece of cold-iron, exhaustion was entirely replaced by overwhelming triumph.
He picked up a small magnifying crystal and examined his work. On a piece of metal no larger than a thumb, Lin Tian had flawlessly engraved exactly three hundred and twenty microscopic runes. They were arranged in a mesmerizing, geometric, deeply integrated pattern.
He channeled a tiny drop of golden Yang Qi into the metal coin.
Hummmmm!
Instantly, the small piece hummed to life. All three hundred and twenty microscopic runes lit up simultaneously in a dazzling blue light. Because the runes were packed so densely and logically, there was zero spiritual energy leakage. The coin began to hover, spinning rapidly, generating a miniature, highly-compressed tornado of wind energy above his palm.
"Incredible," Lin Tian whispered, eyes reflecting the brilliant blue light. "A standard Tier-1 Wind Array uses fifty runes and lifts about ten pounds. This micro-array uses three hundred runes in the exact same surface area. Output multiplied by at least ten. It could effortlessly lift a boulder."
He clenched his fist. The hovering coin dropped safely into his palm.
He had cracked the barrier of traditional runic engraving. He was no longer relying solely on physical mechanisms. He had unlocked the ability to create Peak-Grade magical equipment, maximizing spiritual energy potential through sheer, unparalleled precision.
"With this level of micro-engraving, I can forge spiritual weapons that will shatter the standard defenses of Foundation Establishment experts," Lin Tian sneered, gaze shifting toward the high windows, looking in the direction of the Inner Sect peaks.
He spent the rest of the day and night in total isolation, ruthlessly practicing his new engraving techniques, studying spiritual fire flow, and understanding the fundamental laws of energy conversion within Cultivation. He was rapidly evolving from a clever scavenger into a genuine, terrifying Master Artificer.
The System had upgraded. His knowledge had deepened. His foundation was solidifying into something monstrous.
As dawn broke over Crimson Nimbus Sect, Lin Tian stood, wiping soot and sweat from his chest. His muscles trembled with exhaustion, but his eyes burned with cold determination.
The Inner Sect Promotion Tournament was rapidly approaching. And the Sovereign was ready to show the arrogant geniuses of this world what true, calculated power looked like.
