503: Using myriad treasures as fuel, Dao artifacts are upgraded.

Inside the Immortal Cave, it was so quiet that one could hear a pin drop.

Shen Yuanmo sat cross-legged.

His gaze lingered briefly on the two High Grade Rank Eight Dao Artifacts: the Thunderlight War Hammer and the Purple Light Pill Furnace.

Finally, it landed on the innate thunder soul, which was pulsing with arcs of destructive electricity.

"Rank Eight High Grade, the Materials are acceptable, but the refining technique is far too crude, and the arrangement of the Dao patterns is full of errors."

Shen Yuanmo's critique was calm, but if the two Mahayana Old Ancestors of the Zixiao Holy Land heard it, they would likely crawl back from the Yellow Springs in rage.

These two Dao Artifacts were the sect-protecting treasures that their Holy Land had spent tens of thousands of years and countless resources to successfully refine; they were the trump cards they took pride in.

Yet in Shen Yuanmo's eyes, they were merely 'acceptable' and 'crude'.

This was not arrogance.

After analyzing that True Immortal Stone Tablet and glimpsing the mysteries of the immortal dao rules, his perspective had shifted.

His vision had already been elevated to an entirely new dimension.

Looking back at these mundane Rank Eight Dao Artifacts, he saw childishness and flaws everywhere.

"Very well, I shall recycle this waste; it will serve perfectly as a catalyst."

Shen Yuanmo did not hesitate.

With a thought, the chaos dao embryo within his Dantian Sea of Qi vibrated slightly.

Boom!

An invisible Domain centered on him instantly enveloped the entire Immortal Cave.

The next moment, the Chaos light sphere sealing the Zixiao Holy Land's billion-year treasury emerged in his palm.

He did not take the treasures out one by one; that would be too troublesome.

"Come out."

He spoke two words softly toward the light sphere.

The light sphere burst open!

But the expected scene of soaring treasure light and exploding Spiritual Qi did not occur.

Everything was deathly imprisoned within the Chaos Domain.

Mountains piled high with Top-Grade Spirit Stones crashed down.

Thousands of Spirit Medicines preserved in ten-thousand-year cold jade emitted a refreshing fragrance.

Hundreds of radiant Dao Artifacts and Magic Treasures darted around the Domain like startled fish, letting out bursts of mournful cries.

The High Grade Rank Eight Purple Light Pill Furnace and Thunderlight War Hammer erupted with earth-shattering power, attempting to tear through the Domain's restraints.

If this power were unleashed in the outside world, it would be enough to level a vast mountain range.

But within the Chaos Domain, everything appeared so futile.

"Melt!"

Shen Yuanmo's expression remained unchanged as he performed a hand Seal.

At the core of the Chaos Domain, the shadow of a Ten-Thousand-Foot Dharma Image emerged and opened its abyssal maw.

An irresistible devouring force swept out.

Whether it was Spirit Stones, Spirit Medicine, or those desperately struggling Rank Seven and Rank Eight Dao Artifacts, all were swept inside in one go.

"No!"

"Spare us!"

Some Dao Artifacts that had birthed Artifact Spirits even sent out terrified pleas for mercy.

They felt the arrival of their doomsday.

But Shen Yuanmo turned a deaf ear.

The fate of these objects had been sealed from the moment he obtained them.

Only the two High Grade Rank Eight Dao Artifacts were still putting up a final struggle.

Purple Qi rose from the Purple Light Pill Furnace, manifesting the phantom of a Pill Dao Deity.

The Thunderlight War Hammer crackled with lightning, transforming into a ferocious Thunder Dragon that roared as it charged toward the Dharma Image.

"Noisy."

Shen Yuanmo flicked his finger.

Two streaks of Chaos Qi shot out, accurately striking the core array patterns of the Pill Furnace and the War Hammer.

Buzz!

The might of the two sect-protecting Dao Artifacts instantly vanished; all light dimmed, their power lost, as they were swallowed by the Chaos Dharma Image.

The entire process was smooth and effortless, without a hint of mundane struggle.

If the Artifact Refining Great Grandmasters of the Central Continent saw this, their Dao Hearts would likely collapse on the spot.

Taking the billion-year accumulation of an immortal Holy Land and using it all at once as fuel to be ignited...

How madness! How extravagant!

The mouth of the Ten-Thousand-Foot Dharma Image became a high-speed rotating chaos furnace.

All matter and all Laws were forcibly decomposed, shattered, and reorganized within, turning into energy essence and Great Dao runes.

A brilliant galaxy slowly took shape within the furnace.

Shen Yuanmo reached out, and the great evolution immortal slaying sword and chaos myriad dao armor automatically flew out from his body, hovering before him.

He first looked at the great evolution immortal slaying sword.

High Grade Rank Seven—it was already at the limit of the mortal world.

But for the current Shen Yuanmo, this was far from enough.

"Insight into Origin, activate!"

"Perfect Deduction, activate!!"

Shen Yuanmo closed his eyes, his Divine Thought performing deductions at extreme speed.

The Chaos Myriad Dao Returning Origin Scripture, the properties of countless Divine Golds and Immortal Irons, and even the fragments of immortal dao rules he had just analyzed...

All were used as Materials at this moment, integrated into the new blueprint for the great evolution immortal slaying sword.

What he wanted to refine was not a simple Rank Eight Dao Artifact.

But a supreme weapon of slaughter that could carry his own Great Dao, possess infinite growth potential, and even slay immortals!

After an unknown amount of time, Shen Yuanmo suddenly opened his eyes.

"Now!"

He pointed his finger, and the innate thunder soul turned into a streak of light, actively plunging into the chaos furnace.

Next, he shouted softly at the great evolution immortal slaying sword.

"Dissolve!"

Buzz—!

This Natal Dao Sword that had followed him for so long actually decomposed inch by inch in the air, turning into the most basic Chaos metal liquid.

Then, the billion-treasure essence from the furnace—that brilliant galaxy—along with the Origin power of the innate thunder soul, gathered and poured into it.

Sizzle, sizzle, sizzle!

A piercing sound echoed throughout the Immortal Cave.

A new Sword Core, under the tempering of the Chaos fire, began to reconsolidate.

This time, the sword body was no longer just a single black crack.

Instead, fine, spiderweb-like purple Thunder Patterns emerged.

Each Thunder Pattern contained an extreme aura of destruction, as if they were the manifestation of Heavenly Tribulation.

And the deep crack in the center of the blade became more realistic and darker.

It was as if it truly connected to a Land of Return to Ruins, capable of devouring all things.

A terrifying sword might, far exceeding what came before, began to brew in the Immortal Cave.

The Void Realm could not bear the weight, emitting fine cracking sounds.

"Congeal!"

Shen Yuanmo shouted again.

The Sword Core instantly took shape, and all the pressure and anomalies were completely retracted.

A brand-new longsword floated quietly before him.

It looked even more ancient and restrained than before, without even a hint of sharpness leaking out.

But Shen Yuanmo knew that this great evolution immortal slaying sword had undergone a qualitative change.

"Low Grade Rank Eight Dao Artifact; it is barely enough for now."

He nodded in satisfaction, then turned his gaze to the chaos myriad dao armor nearby.

He followed the same process.

The remaining material essence in the chaos furnace boiled once again.

The chaos myriad dao armor was decomposed and then reforged.

In this reforging, Shen Yuanmo integrated more of his understanding of the Chaos Great Dao, as well as the fragments of immortal dao rules analyzed from the True Immortal Stone Tablet.

The form of the armor did not change much, still maintaining its body-fitting, dark-colored appearance.

However, at every joint and every connection of the armor plates, Chaos-colored Dao patterns as fine as dust were engraved.

"Low Grade Rank Eight; it is finished."

Shen Yuanmo beckoned with his hand.

The great evolution immortal slaying sword entered his Qi Sea to be nurtured by the chaos dao embryo.

The chaos myriad dao armor turned into a streak of light, covering his body before fading from view.

The entire process was silent and did not trigger any Artifact Tribulation.

Just as Daoist Xinghe had said, his Natal Dao Sword had long since perfectly fused with his own aura and Great Dao.

The Heavenly Dao could not sense it.

Or rather, in the eyes of the Heavenly Dao, these Magic Treasures were simply parts of Shen Yuanmo's body.

"Very good."

Shen Yuanmo stood up, feeling the surging power within him and the brand-new changes brought by the rank-up of the two Dao Artifacts.

He was confident that if he faced that True Immortal phantom again, he would not even need to use Dao Slash.

Relying solely on the strength of his Physical Body and Magic Treasures, he could blow it apart with a single punch.
