The Yin-Yang Spiritual Fire ignited the golden bamboo, and the natal magic weapon was formed.

Compared to the silver thunder bamboo, the thunderous power contained within the gold thunder bamboo is purer and more domineering, making it an excellent divine material for refining top-tier Magic Treasure.

He took a deep breath, walked up to the two stalks of gold thunder bamboo, and followed the same procedure, using the thunder slaying saber to carefully cut them down, then stowed them away along with the two hundred-plus precious golden thunder bamboo leaves into his Storage Pouch.

Looking at his once-empty Storage Pouch now filled to the brim, a satisfied smile appeared on Lin Yuan's face.

He sat down cross-legged, flipped his palm, and a flame, swirling with black and white colors and seemingly containing Chaos, rose up in his palm.

Yin-Yang Spirit Fire!

"Go!"

Lin Yuan flicked his finger, and the Yin-Yang Spirit Fire expanded in the wind, transforming into a massive black and white furnace suspended in mid-air. With a focused expression, he cast the two incomparably precious pieces of gold thunder bamboo into the furnace.

"Hiss, hiss—!"

As soon as the gold thunder bamboo entered, it began to melt rapidly under the terrifying high temperature of the Yin-Yang Spirit Fire. The Impurities within the bamboo joints were burned into nothingness by the extremely Yang and rigid flame power, while its purest Origin essence was perfectly preserved under the extremely Yin and cold ice flame.

One Yin and one Yang, one cold and one hot—these two diametrically opposed forces, under Lin Yuan's exquisite control, reached a perfect balance, pushing the "purification" step in Artifact Refining to the extreme.

Although Murong Yue had lost her memory, the instincts of a Nascent Soul Cultivator and a Formation Master Grandmaster remained. She could not understand Lin Yuan's specific operations, but she could clearly feel the terrifying energy contained within the black and white furnace, as well as Lin Yuan's fluid and effortless Artifact Refining technique.

In her beautiful phoenix eyes, shock and admiration involuntarily emerged.

In her remaining cognition, all Artifact Refiners relied on earth fire, wielded heavy hammers, and tempered their work thousands of times before they could create an object. When had she ever seen such a method as Lin Yuan's, using his own spirit fire as a furnace to refine treasures out of thin air?

Time passed bit by bit.

Inside the furnace, the two pieces of gold thunder bamboo had completely transformed into a mass of spirit liquid the size of a human head, with golden electric arcs constantly jumping within it. This mass of spirit liquid was pure to the extreme, as if it were the Origin of thunder, emitting a heart-palpitating pressure.

Purification, complete!

Next was shaping.

Lin Yuan's gaze suddenly became sharp, and his hands began to form hand seals at a dizzying speed.

"Divide!"

He let out a low shout, and his Divine Sense, like an invisible carving knife, precisely pierced into that mass of golden spirit liquid.

Hum—!

The golden spirit liquid trembled violently, and then, in Murong Yue's horrified gaze, that mass of spirit liquid was forcibly divided into ninety-nine small liquid droplets, identical in size and indistinguishable in aura!

"This... how is this possible?!" A monstrous storm surged in Murong Yue's heart.

To precisely divide a complete mass of spirit liquid into ninety-nine parts while maintaining its spirituality—what kind of terrifying control force did this require? This was no longer something a third-grade Artifact Refiner could achieve; in the entire Eastern Region, third-grade was the limit!

"No... how do I know this?" Murong Yue was stunned, but was immediately pulled back to reality by Lin Yuan's voice.

"Condense!"

He brought his hands together, and the ninety-nine golden liquid droplets simultaneously began to stretch and deform. Under the guidance of his Divine Sense, they rapidly condensed into prototypes of Flying Sword, each only a finger's length, with an archaic shape and slender blades.

The ninety-nine sword embryos floated in the furnace, exhaling golden lightning, with chilling Sword Qi.

"Engrave!"

A brilliant light flashed in Lin Yuan's eyes. Using his fingers as a pen and his magic power as ink, he began to engrave complex and profound Formation spirit patterns onto those tiny sword embryos.

His movements were fast to the extreme. Runes containing the ultimate truths of Heaven and Earth flowed from his fingertips, precisely branded onto the sword embryos.

Spirit Gathering Formation, Sharp Metal Formation, Armor Piercing Formation, Lightning Attraction Formation...

One high-level Formation after another was, in an incredible way, miniaturized by him and perfectly integrated into the small sword bodies.

Murong Yue was completely numb.

Engraving Formations for ninety-nine Flying Sword simultaneously, this... this must be something that can only be done when a First-Grade Formation Master and a First-Grade Artifact Refiner exist at the same time!

This thought exploded in her mind like a thunderclap.

She stared blankly at the man sitting cross-legged with a focused expression, and in her heart, besides admiration, a sense of unprecedented awe arose.

However, she could not help but feel secretly delighted.

Such a powerful, such a perfect man was her brother, the person closest to her.

For a moment, girlish sentiments intertwined with a sense of awe, causing her entire being to fall into a complex yet sweet state of emotion.

"Merge!"

With Lin Yuan's final soft shout, the spirit patterns on the ninety-nine gold thunder bamboo flying swords suddenly lit up, emitting a clear and melodious sword hum.

Hum—!

The black and white furnace dissipated, and ninety-nine small swords, entirely crimson gold and wreathed in fine electric arcs, circled and danced around Lin Yuan like a school of joyful fish. Each Flying Sword emitted the powerful fluctuations of a supreme grade Magical Artifact, and the sharp Sword Qi even sliced ripples into the surrounding air.

It's done!

Lin Yuan slowly opened his eyes, looking at this group of new "partners," a satisfied smile appearing on his face.

The "Grand Void Sword Art" he Cultivated had two powerful techniques. The Six Harmony Swords he used before, although supreme grade Magical Artifacts, were too few in number to unleash the full power of the sword art to its extreme.

But now, with these ninety-nine gold thunder bamboo flying swords that shared the same root and Origin and were connected in heart and mind, his strength would welcome a qualitative leap!

The Golden Core chapter of the "Grand Void Sword Art" recorded that when the number of Flying Sword reached ninety-nine—the number of returning to one—one could set up the true "Grand Void Sword Formation." Once this Formation was deployed, the ninety-nine Flying Sword would transform into Formation bases, drawing upon Heaven and Earth Spiritual Qi to form their own Sword Domain. Those who entered the Formation would be shredded by endless Sword Qi, and once trapped, they could never easily escape.

With his current Early Golden Core Stage Cultivation, relying on this Formation, killing a Nascent Soul Cultivator while crossing levels was no longer a pipe dream!

Besides the sword Formation, the move "Heavenly Waterfall Sword Rain" had also received an epic-level enhancement.

Previously, when six swords were unleashed together, they could manifest a hundred Sword Qi phantoms, which was already quite powerful.

But now, with ninety-nine swords unleashed together, what kind of earth-shattering scene could they manifest?

Lin Yuan felt heroic and ambitious in his heart, with an urge to vent it all out.

He stood up tall, his gaze sweeping toward a bare stone mountain in the distance, and the corners of his mouth curled into an arc.

"Just right, I'll use you to test my saber... no, to test my sword."

With a thought, the ninety-nine gold thunder bamboo flying swords instantly converged, hovering in front of him.

"Go!"

Lin Yuan pressed his fingers together like a sword and pointed forward.

Swish—!

The ninety-nine gold thunder bamboo flying swords transformed into ninety-nine streaks of golden light, instantly cutting through the sky and appearing above that stone mountain.

"Heavenly Waterfall Sword Rain!"

Accompanying Lin Yuan's low shout, an astonishing scene occurred.

The ninety-nine gold thunder bamboo flying swords vibrated at high speed in the air, and the Formation spirit patterns on the sword bodies lit up simultaneously. They stirred the rich thunder-attribute Spiritual Qi in this Heaven and Earth, and using themselves as the matrix, manifested thousands upon thousands of identical golden Sword Qi phantoms!

In an instant, the entire sky was dyed a brilliant gold.
