207: The yin is melted and the yang is forged, and the blade blank is initially solidified.

The pure white earth core fire marrow, like a furious seraph, tightly enveloped the dark, deep nine nether cold iron that emitted a Soul-freezing Evil Qi.

"Hiss—!!!!"

Extreme heat and extreme cold, ultimate Yang and ultimate Yin, these two existences with completely opposite attributes but terrifyingly high energy levels, erupted in an unprecedented fierce conflict the moment they made contact!

It wasn't a deafening explosion, but a more heart-pounding, insane annihilation and confrontation on an energy level! The white light of the earth core fire marrow and the faint light of the nine nether cold iron intertwined and eroded each other, emitting a strange sound, as if countless tiny ice crystals were thrown into a furnace, or as if billions of vengeful spirits were screaming in raging flames! A large amount of white steam and black smoke rose, which was an anomaly produced by the extreme consumption of energy.

The black platform trembled violently, and even the entire magma lake below it churned endlessly!

Li Ao stood at the center of the storm, his expression as solemn as water. His hand seals changed like flying, and his Soul Power poured out with unprecedented intensity, like the most precise controller, firmly restraining the violent earth core fire marrow, precisely concentrating its heat and destructiveness on the nine nether cold iron, ensuring that it would melt while also preventing the Yin-cold Evil Qi from being completely incinerated by the ultimate Yang fire.

This was an extremely dangerous balance. If the heat was slightly weaker, the nine nether cold iron would not melt; if the heat was slightly stronger, the Evil Qi would be completely lost, and the nine nether cold iron would become ordinary iron.

Veins bulged on his forehead, and beads of sweat were instantly evaporated by the terrifying high temperature as soon as they seeped out. The nirvana star core rotated at an unprecedented speed within his Qi Sea, continuously providing pure Nirvana Power. This power was not used for destruction at this moment, but as a supreme "rule" power, forcibly intervening in the conflict between the Fierywhite and the faint dark, harmonizing, suppressing, and guiding the two towards an incredible—Fusion!

Gray-gold Qi flow spread out from Li Ao's body, like a third force, wrapping around the core of the fiercely conflicting energy.

Time seemed to become thick and slow at this moment.

One hour, two hours... Under Li Ao's relentless consumption of Soul Power and Nirvana Power, the fierce confrontation finally gradually subsided. The indestructible form of the nine nether cold iron, under the continuous scorching of the earth core fire marrow, began to slowly soften and deform at the edges, like solid ice encountering warm sunlight, seeping out tiny drops of dark black liquid.

These liquid drops were not evaporated by the flames, but instead, as if possessing life, flowed slowly under the guidance of the gray-gold Qi flow. The Yin-cold Evil Qi within them was perfectly preserved, and even became more pure and concentrated under the refining of the extreme high temperature!

The smelting was progressing towards success!

But Li Ao dared not relax in the slightest. He carefully controlled the process, adding auxiliary Materials used to stabilize the energy structure into the gradually melting dark black liquid according to a specific sequence and proportion.

"void crystal stone", transformed into specks of silver light, merged into it, imbuing it with an affinity for space.

"Earth Mother Qi", like a wisp of condensed yellow flowing light, seeped in, increasing its profoundness and toughness.

Various rare auxiliary Materials, one after another, transformed into pure medicinal power or energy flow, harmonizing the conflicts between the main Materials and stabilizing the structure of the Saber embryo that was about to take shape.

Another long hour passed.

Finally, all the nine nether cold iron and auxiliary Materials completely transformed into a rolling, wriggling, dark black liquid about half a person's height! This liquid no longer emitted bone-chilling cold, but contained a deep, light-devouring darkness. On the surface of the liquid, silver spatial ripples occasionally swayed, and earthy yellow profound halos circulated. At its core, there was an unwavering gray-gold, which was the Saber Intent of Nirvana Power that Li Ao had initially imprinted within it!

The first step, smelting and initial Fusion, was successful!

Li Ao let out a long breath of turbid air mixed with high-temperature white mist, the fatigue in his eyes was undeniable, but there was more of a sharp glint.

He did not stop; forging a weapon was like sailing against the current, falling back if not advancing!

Next, was the shaping!

His gaze sharpened, and he cupped his hands. The dark black liquid seemed to be grasped by an invisible large hand, slowly stretching and shaping!

This was not simple forging, but using the Soul as a hammer and will as an anvil!

"Buzz—!"

Powerful Soul Power, like billions of invisible forging hammers, furiously hammered and forged the liquid with an arcane frequency! Each "hammering" was accompanied by the injection of Li Ao's own Saber Intent, as well as the fine-tuning and optimization of the internal structure of the Materials!

The liquid, under the Soul hammer, trembled violently, emitting a clear and melodious sound like a Dragon's roar! Its form began to change rapidly, gradually elongating, with both ends becoming sharp and the middle thick. The Chickform of a long Saber began to appear!

The Saber body was straight and slightly wide, carrying an Aura of unwavering determination. At the Saber guard (handguard), Li Ao deliberately guided the Materials to form a simple yet sharp arc, like an eagle spreading its wings, ready to fly.

The entire shaping process was as fast as lightning, yet it felt as if it had undergone millions of temperings.

When the last Soul hammer strike fell—

"Clang—!"

A clear and incomparably melodious Saber hum, as if capable of severing all shackles in the world, suddenly erupted from the formed Saber embryo!

The sound penetrated the cave, and even penetrated the barrier set by Li Ao, clearly audible amidst the roar of the external volcano!

A Saber embryo, entirely black, about four feet three inches long, three fingers wide, and ancient yet sharp in form, quietly floated within the pure white earth core fire marrow!

The Saber embryo was complete!

It was no longer a mere heapof Materials, but had initially acquired the form and Soul of a "Saber"! The pitch-black Saber body seemed to absorb all light, and only at specific angles could one vaguely see the silver spatial ripples and gray-gold Nirvana Power essence flowing within it.

However, this was only the beginning. This Saber embryo still lacked the most core "bone" and "Soul"—the Fusion of the dragon emperors reverse scale and the balance of the solar essence gold.

Li Ao looked at the initially formed Saber embryo, with no hint of complacency in his eyes, only even more extreme focus. He took out the dragon emperors reverse scale, which emitted a purple-gold halo and contained vast Dragon prestige and spatial fluctuations.

Next, was the true test. The difficulty and risk of perfectly integrating a divine object of this Rank, the dragon emperors reverse scale, into the Saber embryo to make it the "spine" of the Saber, far exceeded that of smelting the nine nether cold iron!

He took a deep breath, adjusted his state to its Peak, and cast his gaze towards the Dragon scale that symbolized power and space.
