Boom!
Han Xuanji's mind reeled, feeling an endless torrent of Artifact Refining Profound Truths surging into the depths of his Sea of Consciousness.
"With heaven and earth as the furnace, the Great Dao as the firewood, and all creation as Materials..."
Han Xuanji murmured.
This Artifact Refining Legacy was the Nine Revolutions Heavenly Craft Art, all-encompassing, exhausting the mysteries of the Artifact Dao, with every word a pearl of wisdom, a Fusion of "Artifact" and "Dao."
He didn't know how much time had passed.
"Very good."
Han Xuanji slowly opened his eyes, within which Artifact Dao runes seemed to flicker like stars, eventually receding completely, returning to a state of calm.
The vast Artifact Refining knowledge in his mind quietly settled, transforming into his own foundation.
"The Immortal Materials I obtained from previous Sign-ins can finally be put to use now."
Han Xuanji's mind delved into the System space, quickly scanning through it.
He had been Signing in for many years.
For example, the treasure vaults of Sects like the Shenxuan Sect, the imperial treasuries of Great Xia and Great Ming...
When these forces were at their peak, they even had Immortals presiding over them, their ten-thousand-year foundations were unimaginable.
Among them, Immortal Artifacts were naturally rare, something one could only hope to stumble upon.
However, top-tier Heaven And Earth Treasures capable of refining Immortal Artifacts were not absent.
In fact.
Many times, for powerhouses of the Ascension Realm, the most difficult part of refining an Immortal Artifact was not collecting the Materials, but finding an Artifact Refining Immortal Grandmaster who could control such Materials.
Immortal Artifacts involved the Law of the Immortal Dao; even a so-called Artifact Refining Grandmaster, pouring their life's blood into it, could often only refine a quasi-Immortal Artifact whose power approached that of an Immortal Artifact.
Many Immortal Artifacts on the Kyushu Continent were actually forged by the same person.
This person was named "Craftsman Immortal," and it had been thousands of years since he disappeared.
For many years, no new Immortal Artifacts had been born in Kyushu.
This was inextricably linked to the departure of this "Craftsman Immortal."
"Five Elements Immortal Jade, Grand Unity Immortal Gold, Void Divine Crystal, Star Tear..."
Han Xuanji silently recited, picking out Heaven And Earth Treasures one by one from the System space.
These were all rare treasures, encountered once in ten thousand years, enough to cause Ascended Immortal powerhouses to fight over them.
Normally, using just one type of Immortal gold, supplemented by other precious Materials, would be enough to refine an Immortal Artifact.
Yet, at this moment, Han Xuanji held over a dozen kinds.
Just thinking about it made Han Xuanji's heart burn with excitement.
"Now I hold over a dozen kinds of top-tier Immortal Gold, and I am blessed with the supreme Legacy of an Artifact Refining Immortal Grandmaster, plus I can fuse some Immortal Artifacts into it as nourishment.
The Immortal Artifact that is ultimately born will definitely be extremely powerful."
Han Xuanji thought to himself.
This Artifact Refining Immortal Grandmaster's Legacy came at just the right time.
He had previously obtained these Immortal Materials but was unable to utilize them, like guarding a treasure mountain without knowing how to enter.
He was still worrying about how to use these Materials.
After all, finding an Artifact Refining Immortal Grandmaster was not easy.
Now he himself was an accomplished Artifact Refining Immortal Grandmaster, so he didn't have to worry about the other party playing tricks or cutting corners.
"As for the Artifact Refining location, this Ten Thousand Swords Pool itself is an excellent Artifact Refining treasure ground."
Han Xuanji's gaze was like lightning, sweeping across the ancient Sword Tomb before him, where Sword Qi soared to the heavens.
This entire Ten Thousand Swords Pool, which had nurtured countless precious swords and accumulated ten thousand years of Sword Intent, was also a Material in his eyes.
Perhaps... he could fuse it into his Immortal Artifact as well.
A month later.
[Congratulations to Host for successfully Signing in at Ten Thousand Swords Pool, obtaining the Heaven And Earth Treasure "Ice Soul Immortal Gold."]
"Another good Material."
Han Xuanji stood alone at the edge of the Ten Thousand Swords Pool, silently nodding.
Over the past month, the Ten Thousand Swords Pool had yielded numerous rewards from Sign-ins, all of which were Heaven And Earth Treasures rarely seen in the outside world.
The Ten Thousand Swords Pool at this moment was vastly different from when he first arrived.
Countless divine weapons and sharp blades in the pool had melted, and beneath the water's surface, myriad sword shadows could vaguely be seen rising and falling, swimming about. The chilling Sword Qi was bound by an invisible force, emitting a low hum, the entire pool resembling a Heavenly and Earthly furnace.
"The better the Materials incorporated into an Immortal Artifact, the higher the quality and potential of the Immortal Artifact will be."
"And to refine one's own destined Immortal Artifact, it's best to fuse one's own Immortal Dao Law... This way, the Immortal Artifact can be better utilized and grow."
Han Xuanji's eyes gleamed as he gazed at the churning pool water, murmuring to himself.
He hadn't just waited idly for this month.
The first step of preparation was already complete; using the Ten Thousand Swords Pool's accumulated ten thousand years of swords as fuel, he had thoroughly ignited this Heavenly and Earthly furnace!
The dozen or so rare Immortal Golds had already been cast into the depths of the pool water by him using specific incantations, and under the combined calcination of the Sword Qi at the bottom of the pool and the true fire from the earth's core, they had begun a slow and profound Fusion.
It also included many Immortal Artifacts and Magical Artifacts he had previously Signed in for.
Artifact Refining, begin!
Han Xuanji took a deep breath, his body surging with Immortal light, his robes fluttering without wind.
His hands moved like dancing butterflies, forming extremely intricate Artifact Refining Immortal Seals. Each seal he cast resonated with the Laws of Heaven and Earth.
"Heaven and Earth as the furnace, the Great Dao as the fire..."
Han Xuanji chanted, the ancient Artifact Refining Immortal incantations transforming into tangible golden runes, circling him like stars, then raining down into the Ten Thousand Swords Pool.
Rumble!
As the Immortal incantations descended, the entire Ten Thousand Swords Pool completely boiled over.
The viscous, mercury-like pool water spun wildly, forming a massive whirlpool.
At the center of the whirlpool, a scorching white divine fire from the earth's veins shot skyward, transforming into a platinum fire pillar connecting heaven and earth.
Within the fire pillar, a dozen or so Immortal Golds could vaguely be seen colliding and fusing, erupting in multicolored light, sometimes like Dragons and tigers battling, sometimes like stars shifting.
The ten thousand years of Sword Intent floating in the Ten Thousand Swords Pool seemed to be summoned, emitting deafening sword cries, transforming into streaks of light, rushing one after another into the platinum fire pillar, becoming nourishment for the birth of the Immortal Sword.
By the pool, the temperature was high enough to melt everything, and space itself was slightly distorted.
Han Xuanji stood before this world-destroying spectacle, yet remained as unmoving as a reef.
His expression was utterly focused, fine beads of sweat seeping from his forehead.
His mind was completely immersed in the Artifact Refining, guiding the violent flames and Sword Intent to fuse, sorting out the collision of various Laws, and imprinting his own comprehended Immortal Dao Law, thread by thread, into the Artifact embryo forming at the core of the furnace.
This was a complex and extremely important process.
And this process lasted for a full seven days and seven nights!
Until the light of the fire pillar finally converged, forming a light mass about a zhang in diameter, suspended above the whirlpool.
On the surface of the light mass, countless tiny sword-shaped Dao patterns flickered and flowed, emitting a sharp aura that made heaven and earth tremble.
The Sword Embryo, formed!
Han Xuanji's eyes burst with unprecedented brilliance, his hand seals suddenly changed, and he let out a clear shout:
"All Laws return to their origin, sword be formed!"
He pointed his fingers like a sword, his fingertips condensing his purest essence blood, and he pointed it at the light mass in mid-air.
Inside the light mass, the Sword Embryo began to take shape, and the Dao patterns on the sword body interconnected.
As the last Dao pattern was carved, the sword's main body finally erupted with brilliant light, like a great sun.
The sword body was entirely pure white, radiating a silvery luster, permeated with wisps of supreme Sword Dao Laws.
"It's finally done."
Han Xuanji's eyes lit up.
As soon as this sword was formed, it recognized him as its master.
At the same time.
As if sensing the imminent birth of the Immortal Sword.
The originally clear sky, stretching for thousands of miles, suddenly saw a dark cloud rolling in, covering the sky, and faint rumbling of thunder could be heard.
