Immortal Supreme: Sovereign of the Grand Dao-Chapter 316: Dao Devouring Martial Spirit Breakthroughs to God Grade!

Chapter 316: Dao Devouring Martial Spirit Breakthroughs to God Grade!

The moment the True Chaos Essence made contact, the Devouring Spirit began to change.

The black vortex trembled. Its rotation accelerated. The darkness within it grew deeper, more profound, as if it was becoming a gateway to true nothingness rather than just an empty void.

Arthur watched intently as the spirit began to ascend.

Peak Heaven Grade Tier 10... breaking through...

A flash of silver light.

**Tier 1 Immortal Grade.**

But the transformation didn’t stop. The True Chaos Essence continued to infuse into the spirit, forcing it to evolve at an unprecedented rate.

Tier 2... Tier 3... Tier 4...

The process accelerated. Within his soul space, Arthur could feel the strain. Forcing such a rapid evolution was dangerous, but the True Chaos Essence provided a perfect foundation—it was, after all, the origin of all things.

Tier 5... Tier 6... Tier 7...

The vortex was no longer just black. Hints of color began to appear within its depths—the same multicolored shimmer as the Chaos Dragon’s scales.

Tier 8... Tier 9... Tier 10...

**Peak Immortal Grade.**

But Arthur didn’t stop. He pushed further, feeding more True Chaos Essence into the transformation.

The spirit broke through again.

**Tier 1 Divine Grade.**

The vortex now pulsed with power that made Arthur’s soul tremble. This was a level of power that mortal realms should never witness. A Divine Grade martial spirit in a lower realm was an impossibility—yet here it was, manifesting within Arthur’s very being.

The process became slower now. The higher the grade, the more True Chaos Essence was required, and even the Chaos Dragon could only extract so much from the void at Arthur’s current cultivation level.

Tier 2... Tier 3...

Each advancement took longer than the last. Arthur poured all his focus into maintaining the delicate balance, ensuring the spirit didn’t destabilize from the rapid evolution.

Tier 4... Tier 5...

Hours passed in his soul space, though only minutes passed in the outside world.

Tier 6... Tier 7...

The strain was becoming immense. Arthur’s soul power was being depleted rapidly just maintaining the process. But he refused to stop. He could feel that the spirit was close to another breakthrough.

Tier 8... Tier 9...

Almost there. 𝚏𝕣𝐞𝗲𝐰𝕖𝐛𝐧𝕠𝕧𝚎𝚕.𝐜𝚘𝗺

With one final push, Arthur channeled the last reserves of True Chaos Essence the Chaos Dragon had extracted.

Tier 10.

**Peak Divine Grade.**

The Devouring Martial Spirit had reached a level that put it among the supreme powers of the multiverse. But still, Arthur felt it could go further.

"One more," Arthur gritted his teeth. "Break through to God Grade."

He commanded the Chaos Dragon to channel every last bit of True Chaos Essence it had accumulated.

The dragon complied. A massive surge of primordial energy flooded into the vortex.

The Devouring Spirit trembled violently. For a moment, Arthur feared it might shatter from the strain.

But then—

*BOOM*

A soundless explosion rocked his soul space.

The vortex compressed, condensed, transformed. The multicolored shimmer intensified until the spirit was no longer purely black but contained within it the essence of all colors, all elements, all existence.

**Tier 1 God Grade.**

Arthur gasped, his soul power completely depleted, it was like he overdraft what his current cultivation could handle even his core soul power seemed endless.

But nevertheless, satisfaction filled him.

"Success."

The Devouring Spirit had reached God Grade—a level that only a handful of beings across the entire multiverse possessed.

But Arthur knew this was just the beginning. Eventually, with enough time and True Chaos Essence, he could push it even further. Maybe even to Supreme Grade like the Chaos Dragon itself.

However, that would take time. Years, perhaps decades. The amount of True Chaos Essence required increased exponentially with each grade, and the Chaos Dragon could only extract so much, especially while Arthur’s cultivation was still limited.

"This will have to do for now," Arthur decided. "As my cultivation increases, the Chaos Dragon’s extraction rate will improve. Eventually, I’ll upgrade all my spirits to Supreme Grade. But for now, having one God Grade spirit and one Supreme Grade spirit is already beyond absurd."

He dismissed the spirits back into his soul and took a moment to recover his depleted soul power.

"Now, over to the main course of my seclusion today."

After resting and replenishing his energy, Arthur turned his attention to the most immediate concern—completing his foundation.

According to the Nine Heavens Universal Scripture, he needed to forge an 81-star foundation across nine levels, with each level containing nine stars arranged in a specific formation.

Every genius in the multiverse struggled to forge a nine-star foundation. Those who managed it were considered once-in-a-millennium talents.

Upper realm geniuses could sometimes forge a perfect nine-star foundation with all nine stars of equal quality and perfect arrangement.

But Arthur’s technique demanded perfection across **nine sets** of nine stars each.

He checked his current progress and nodded with satisfaction.

"Seventy-two stars. Eight complete sets. I only need to forge one more complete set to finish the ninth level."

Once he completed all 81 stars, his foundation would be complete. At that point, breaking through to the Martial Emperor Realm would be trivial—he could do it with a single thought.

But he wouldn’t break through yet. Not until the time was right.

The secret realm would be the perfect opportunity to showcase his strength while still maintaining the appearance of being in the Half-Step Martial Emperor Realm. If he broke through too early, it would attract too much attention.

Morever he doesn’t want to risk not being able to entered due to his breakthrough.

Arthur stood up, his decision made.

"Aixen," he called out.

The artifact spirit appeared instantly. "Yes, Master?"

"I’m entering the time chamber. I’ll forge the final nine stars and consolidate my foundation completely. With the 100:1 time dilation, I should have plenty of time."

"As you command, Master. The time chamber is prepared and waiting."

Arthur took one last look around the meditation chamber, then walked toward the deepest part of the palace.

The time chamber was located in the very heart of the Nine Heavens Palace. It was a space that existed outside normal reality, where time flowed according to the palace’s will rather than the natural laws of the universe.

As Arthur entered, he felt the shift immediately. The air was different here—thicker, heavier with potential. Every second in this place carried weight.
