Seal

The myriad laws of heaven and earth were unfathomable, and Divine Formulas were merely one kind among them.

As for so-called Divine Arts, they were even more profound and mysterious.

Heaven and earth contained all manner of miraculous powers.

Once unleashed, they could erupt with utterly terrifying might. Such techniques were known as Divine Arts.

Even Sovereign Stage experts regarded Divine Arts with great importance.

However, Divine Arts had stringent cultivation requirements, and their formulas were exceedingly rare.

Yet Futu Yun happened to possess one—and it was one he had created himself.

With his status, let alone Divine Arts, even Divine Abilities were nothing beyond his reach.

But this Divine Art had been forged with the Forest of Death Seal as its framework, Black Divine Lightning as its flesh and blood, and the Immortal Bird Bloodline as its soul.

It had been condensed through the Nine Revolutions to Sainthood: the Undying Thunder Seal!

Nine was said to be the ultimate number, but the "Nine Revolutions to Sainthood" here involved far more than merely nine revolutions.

It had been forged layer upon layer from Black Divine Lightning and overlaid with Forest of Death Seals. Even Mandala had no idea how many layers it contained.

The remaining Black Divine Lightning had once been far from sufficient to support a Divine Art.

That was why Futu Yun had gone to the Northern Heavens Spiritual Academy, absorbing the Black Divine Lightning within the Thunder Realm.

He had even needed to absorb Thunder Spirits to strengthen the Undying Thunder Seal.

As for the Thunder God Pill that could help a Ninth-grade Sovereign break through to the Earthly Sovereign realm?

He did not think much of it at all.

It was not as though he could not obtain pills capable of helping someone break through to the Earthly Sovereign realm.

For instance, the Supreme-Breaking Pill was specifically used to shatter the shackles between a Ninth-grade Sovereign and a Lower Earth Supreme.

That thing was far safer than the Thunder God Pill.

The Thunder God Pill's medicinal effect was simply brute force overcoming all.

It was one thing for a divine beast like the Northern Sea Dragon Kun to consume it, but humans absolutely could not withstand it.

Black Divine Lightning was relatively gentler. Now that he had the Undying Thunder Seal,

even without Mandala, he could mobilize this ownerless Black Divine Lightning.

As more and more Forest of Death Seals were layered upon it, the Undying Thunder Seal advanced from a Minor Divine Ability all the way to a Grand Divine Art.

It then reached the Quasi-Great Perfection Divine Art level before finally breaking through into a Perfect Divine Art!

When it advanced into a Grand Divine Art, his cultivation entered the middle phase of the Spirit Wheel Stage.

When it reached the Quasi-Great Perfection Divine Art level, his cultivation rose to the late phase of the Spirit Wheel Stage.

And the instant it broke through into a Perfect Divine Art, he had already reached the peak of the Spirit Wheel Stage, just one step away from the Divine Soul Stage!

In the original story, Mu Chen had broken through with the help of a Divine Soul Yin-Yang Ganoderma.

It was an extremely rare heavenly treasure.

Not only was it greatly beneficial to Divine Soul Stage experts, it could also allow someone in the late Spirit Wheel Stage to directly enter the Divine Soul Stage.

But in Futu Yun's eyes, such a method was far too crude.

A Divine Soul forged through the Divine Soul Yin-Yang Ganoderma was merely an ordinary Divine Soul.

What Futu Yun sought was a special Divine Soul, much like a special physique!

Still, Mu Chen could not be blamed for that.

Although he possessed the bloodline of the Pagoda Ancient Clan,

his mother had left behind only an incomplete Great Pagoda Art before she departed, without even the slightest cultivation resource.

Even if Mu Chen knew the method to cultivate a special Divine Soul, he could only look on helplessly.

But Futu Yun was entirely different.

Countless black thunder pillars, each thousands of feet tall, shot into the sky from the sea of lightning.

They then gathered above the lightning sea, ultimately transforming into a black Thunder Spirit without any fixed form.

Thunder liquid poured from its body like streams of lightning.

Two exceptionally dark bolts of lightning emerged, like eyes condensed from black holes, staring fixedly at Futu Yun.

The formless black Thunder Spirit seemed to let out an enraged roar as black lightning ran wild, blanketing an area several thousand feet wide.

Yet at a single glance from Mandala, it immediately wilted.

It even had no choice but to take the initiative to merge into the Undying Thunder Seal in Futu Yun's palm.

He then took out a black lotus roughly ten feet in size, its form flowing endlessly as though it were liquid.

This Thunder God Lotus was a rare heavenly treasure. Like the Thunder God Pill, it had only an extremely small chance of being born amid lightning.

Having read the original story, Futu Yun knew that this sea of lightning would nurture both a Thunder God Pill and a Thunder God Lotus.

The Thunder God Pill went to the Northern Sea Dragon Kun, while he gladly claimed the Thunder God Lotus.

As he activated the Undying Thunder Seal with all his strength, the power from the Thunder Spirit was continuously refined.

In the end, it flowed without cease into his sea of qi alongside the Thunder God Lotus's energy, pouring into the spiritual energy light wheel.

A peculiar sensation suddenly rose within Futu Yun's heart, as though ripples had spread across a tranquil deep pool.

At that moment, the spiritual energy light wheel stopped turning, and ripples of spiritual energy undulated across its surface.

Immediately afterward, Futu Yun sensed spiritual energy beginning to surge forth, ultimately gathering above the spiritual energy light wheel.

When the light faded, a tiny figure of light could be seen sitting cross-legged atop the spiritual energy light wheel.

Its features vaguely resembled Futu Yun's, yet they were too indistinct to be seen clearly.

The instant that tiny figure of light took shape, a wondrous feeling flooded Futu Yun's heart.

With a shift of his mind, his vision abruptly changed—he had actually become the tiny figure of light seated upon the spiritual energy light wheel.

This was the most fundamental difference between the Divine Soul Stage and the Spirit Wheel Stage:

Once one condensed this Divine Soul, one had truly stepped into the Divine Soul Stage.

After humans entered the Divine Soul Stage, they gained the ability to refine the essence souls of spiritual beasts.

Moreover, once one stepped into the Divine Soul Stage, the tiny Divine Soul could automatically circulate cultivation arts and spiritual formulas, allowing autonomous cultivation.

Combined with the cultivation of the main body, the efficiency would be multiplied, greatly benefiting the growth of one's cultivation.

However, at that very moment, he suddenly sensed a hum coming from within his body.

After pausing in slight surprise and carefully sensing it, he discovered that a piece of information had abruptly surfaced in his mind.

Within the Great Thousand World, Divine Arts surpassing the Perfect Divine Art level were known as Divine Ability Arts.

Such Divine Abilities could not only move Sovereign Stage experts, but even Earthly Sovereign-level beings would covet them.

Every Divine Ability possessed world-destroying might. Their level far surpassed Divine Arts, hence the name "Divine Ability."

Having absorbed the Thunder Spirit, the Undying Thunder Seal had now successfully entered the realm of Divine Abilities.

Although it was only the embryonic form of a Minor Divine Ability, it had ultimately become a Divine Ability.

And it was a Divine Ability created by Futu Yun himself, one that could grow alongside him!

However, if he wished to raise the Undying Thunder Seal another level, he would need to seek lightning power stronger than Black Divine Lightning.

After all, the Thunder Spirit itself had been condensed from Black Divine Lightning. No matter how much more Black Divine Lightning he acquired now, it would be of no use.

"Lightning stronger than Black Divine Lightning?" Futu Yun's expression changed slightly.

Black Divine Lightning alone was already enough to cause countless spiritual beasts attempting to reach the Sovereign Stage to perish.

Then what kind of terrifying existence would lightning stronger than Black Divine Lightning be?

It seemed he did not need to think about that for the time being.

But aside from that, he had gained another unexpected harvest:

His true Divine Ability was not the "Undying Thunder Seal," but the most fundamental "Seal"!

The so-called Undying Thunder Seal was merely a branch derived from the Divine Ability, Seal.

Simply put, he could refine all kinds of energy into Seals.

Each Seal required a type of energy as its core seed.

And the grade of that seed's energy directly determined the upper limit of the Seal ultimately cultivated.

Most importantly, while the level of Seal had an upper limit, its quantity had no limit!
