"Since there are only three chances, I absolutely cannot be careless!" Liu Chen deeply understood the importance of this refinement; every step had to be handled with caution.
From the four blades and swords at the entrance, he obtained two Blade Light Gu and two Sword Shadow Gu. Liu Chen carefully put away these precious gu materials, checking them repeatedly to ensure there were no issues before confidently walking to the giant bronze cauldron.
He took a deep breath, steadied his mind, and began preparing for the refinement. First, he activated a Dan Fire Gu, and instantly, a crimson fireball formed in his hand. Liu Chen slowly moved the fireball beneath the bronze cauldron, letting it burn continuously to provide ample heat for the refinement.
Next, Liu Chen unhesitatingly threw ten thousand primeval stones into the cauldron. These primeval stones rapidly melted under the high temperature of the Dan Fire, turning into a pool of white liquid. Liu Chen focused intently on the melting of the primeval stones, ensuring that every single one completely melted.
Once all the primeval stones had melted, Liu Chen immediately added the previously acquired shadow skin and a ball of radiance into the cauldron.
The shadow skin quickly dissolved in the liquid, fusing with the primeval stones, while the radiance shone like a brilliant pearl in the liquid.
Subsequently, Liu Chen threw a sword jade and a blade crystal into the cauldron. The moment these two Materials entered the cauldron, they seemed to be drawn by a mysterious force, rapidly fusing with the other Materials.
As various Materials continued to fuse, the scene inside the cauldron became increasingly wondrous. Liu Chen's own Golden True Essence continuously poured into it, intertwining with the various Materials, forming a picture of light and shadow interweaving like a Tai Chi diagram.
At this critical moment, Liu Chen seized the opportunity and quickly threw two Third Rank Blade Gu into the cauldron. The moment these two Gu worms entered the cauldron, they seemed to ignite, instantly bursting into flames. The Dan Fire burned fiercely, and Liu Chen maintained precise control over the Dan Fire at all times, not daring to relax in the slightest.
After all the gu materials had perfectly fused, Liu Chen unhesitatingly threw the Blade Light Gu and Sword Shadow Gu into it. At that instant, he immediately exerted his full strength to activate the Dan Fire Gu, and the Dan Fire surged violently like a volcanic eruption.
At the same time, the two Gu worms absorbed the two powerful energies contained within the bronze cauldron at an astonishing speed. As time passed, the light became even more dazzling, and the shadow grew darker and deeper. The two were distinctly separated yet gradually merged into one through their interaction.
"Now!" Liu Chen's eyes were sharp, fixed on the bronze cauldron; he knew the opportunity was fleeting.
At this critical juncture, he made a decisive move, quickly extinguishing the Dan Fire Gu's flame, then unhesitatingly activated the Third Rank Ice Crystal Gu.
In an instant, an extreme cold Qi gushed out, instantly freezing the bronze cauldron.
The violent alternation of ice and fire, a double-heavenly ordeal, instantly froze and tempered the light and shadow Gu cocoon. However, in what seemed like a perfect Fusion process, an unexpected incident suddenly occurred.
The cold Qi within the ice crystal unexpectedly began to dissipate uncontrollably, and at an extremely fast rate. This cold Qi swept like a cold current, mercilessly engulfing the Gu worm that was about to be successfully refined, freezing it to death in the blink of an eye.
"Not good!" Liu Chen's heart tightened. Seeing his efforts about to be ruined, he did not panic.
He quickly formed a series of complex hand seals, decisively interrupting the Gu refinement process to reduce the backlash from the failed refinement.
"Again!" Liu Chen's eyes were firm, and he shouted without hesitation. He quickly composed himself, fully dedicating himself to preparing for the second Gu refinement.
Liu Chen did not feel discouraged by this refinement failure.
After all, Gu refinement is an extremely complex and unpredictable art, and failure is commonplace. In fact, successfully refining a Gu worm on the first try is relatively rare.
However, Liu Chen was no ordinary Gu Master. He possessed Lao Mo's five hundred years of accumulated experience, which gave him an understanding and insight into Gu refinement far beyond ordinary people. Although Lao Mo specialized in the Blood Refinement method.
Unfortunately, when refining this Sword Path Gu worm, the Blood Refinement method was not applicable. Therefore, Liu Chen could only rely on ordinary Gu refinement methods to attempt it.
He first melted the solid ice on the bronze cauldron, then once again took out the Dan Fire Gu, preparing to continue the refinement using the same technique as before.
With the lessons learned from the previous experience, Liu Chen's operations this time appeared more skilled and confident. His movements were fluid and unhesitating.
Before long, Liu Chen successfully completed the preliminary steps of Gu refinement, reaching the most crucial final stage. At this point, the Blade Light Gu and Sword Shadow Gu had successfully fused together, forming a preliminary Gu worm prototype.
Liu Chen took a deep breath and unhesitatingly activated the Ice Crystal Gu. In an instant, a biting cold Qi surged out from the Ice Crystal Gu like a turbulent wave, instantly enveloping the entire bronze cauldron.
Under the influence of this powerful cold Qi, the Gu worm began to undergo drastic changes. The tempering of the ice crystals caused the various parts of the Gu worm to gradually fuse together, and the original flaws and imperfections gradually disappeared under the sharpening of the cold Qi.
As time passed, the Fusion of the Gu worm became more and more perfect, eventually completely merging into one, becoming a complete Gu worm.
Following the direction of the transparent ice crystal, a dazzling white light and a pitch-black shadow suddenly bloomed. The light was as bright as day, and the shadow was as deep as night. In this intense light, a Gu worm shot out like a meteor.
The appearance of this Gu worm was very unique; it resembled a pair of black and white bracelets intertwined, landing in Liu Chen's palm.
Liu Chen effortlessly refined this Gu worm. The black and white bracelets respectively entered his left and right wrists, leaving an imprint of a blade and a sword. This imprint, like a tattoo, was deeply etched into his skin, emitting a faint glow.
Liu Chen's heart stirred, and he immediately poured True Essence into both of his hands.
In an instant, his hands seemed to be endowed with life, manifesting a light blade and a shadow sword. This pair of blade and sword were both ethereal and real, as if they existed in another dimension, yet Liu Chen could easily control them.
As True Essence was continuously poured in, the length of this pair of blade and sword also began to extend and retract at will, as if they were controlled by Liu Chen's will. Liu Chen, holding the blade and sword, came before the qing gang stone wall. He took a deep breath, crossed his hands, and with Blade Light Sword Shadow interweaving, he fiercely struck the Green Steel Stone Wall.
With a crisp "swish" sound, the qing gang stone was directly pierced through, faintly revealing the light from inside. Seeing this, Liu Chen was overjoyed; he had not expected this Gu worm to possess such powerful might.
