A dark scroll floated within the faint black light.
Ancient beast patterns covered the scroll's surface, waves of light radiating from it.
As the light gathered, illusory beast shadows formed around the scroll—they roared at one another, their cries ancient and mysterious.
The powerful Divine Formula known as the Four Divine Beasts Constellation Scripture had been created using the spirits of the four cardinal constellations.
This art could summon the spirits of the four cardinal constellations. When the four divine beasts gathered, they could shake heaven and earth.
Though the introduction consisted of only a few short lines, its words could not conceal its overwhelming power and domineering aura.
Futu Yun had agreed to go to the Northern Heavens Spiritual Academy precisely for this special Divine Spiritual Art.
After all, the Northern Heavens Spiritual Academy was different from the Northern Spiritual Academy.
Back then, he had merely mentioned it in passing, and the mentors of the Northern Spiritual Academy had presented him with the Forest of Death Seal.
But the Northern Heavens Spiritual Academy was not comparable to the Northern Spiritual Academy, which was content to remain in one corner.
He could obtain it through coercion or temptation, but that would inevitably create a rift with the forces behind it.
The Pagoda Ancient Clan naturally feared no one, but there was no need to act in such a manner.
In any case, it was all part of his training. The Northern Heavens Spiritual Academy must have extraordinary qualities to rank among the Five Great Academies.
Moreover, as someone who had read the original story, Futu Yun already knew all the opportunities within the Northern Heavens Spiritual Academy and even the Northern Heavens Continent.
Just like the Thunder God Lotus, the Thunder Spirit, and the Four Divine Beasts Constellation Scripture before him now.
If it were merely an ordinary Divine Spiritual Art, it naturally would not be worth Futu Yun making a special trip.
Yet the Azure Dragon, White Tiger, Vermilion Bird, and Black Tortoise were known as the spirits of the four cardinal directions.
Even among transcendent divine beasts, they stood at the very peak. Only a small number of Super Divine Beasts could rival them.
A cultivator needed to comprehend the artistic conception of the Four Spirits.
Without the aura of the Four Spirits' origins, the spirits of the four cardinal directions one condensed would possess only the form, not the essence.
For example, without the killing intent of the metal White Tiger, a White Tiger would merely be a white tiger.
In the original story, Mu Chen had successfully comprehended the artistic conception of the Four Spirits only through the Immortal Catalog.
But what if he cultivated using the true spirits of the four cardinal directions?
Given Futu Yun's status, obtaining the beast souls of the four cardinal spirits might not be easy, but acquiring a scale or claw from them was hardly difficult.
As for whether he could withstand the lingering pressure of the Four Spirits?
His face now carried an indescribable calm, as though even the collapse of heaven and earth could not shake him in the slightest.
This calm came from reason and would not waver due to any external factor—this was the heart demon state of the Supreme Heart Demon Scripture!
In ancient times, there had once been a super fiend known as the Heart Demon Thunder Emperor, who had originated from the Ancient Thunder Palace.
The Thunder God Palace, now a renowned superpower in the Great Thousand World, was the inheritance of the Ancient Thunder Palace.
And the Supreme Heart Demon Scripture was the Thunder God Palace's guardian Divine Ability.
When he had captured the Netherworld Heart Demon Thunder earlier, Futu Yun had already found a fragment of the Supreme Heart Demon Scripture.
According to the original story, its rank could probably reach only the Quasi-Great Perfection Divine Art level.
Moreover, to cultivate the heart demon state, one first needed to condense a Heart Demon Seed.
This seed had to be forged by allowing the Netherworld Heart Demon Thunder to strike the heart countless times.
Its power would seep into the heart, eventually taking shape slowly in its depths.
To many, such a cultivation method was no different from seeking death.
The heart was already the most fragile part of the human body. Even a minor injury could result in grave harm or death.
Who would dare use such tyrannical power as the Netherworld Heart Demon Thunder to attack their own heart?
The moment something went wrong and thunder erupted, the heart would likely burst apart instantly.
Even if an ordinary person obtained the Supreme Heart Demon Scripture, they might not dare cultivate it lightly.
But Futu Yun was different.
He had already refined Hu She's Netherworld Heart Demon Thunder into a beast soul.
Coupled with the fact that he possessed a mutated lightning-attributed Divine Soul, there was no need for such trouble at all.
To him, the heart demon state was more like an innate Divine Ability.
He soon arrived at the Northern Heavens Spiritual Academy's Level Six Spirit Gathering Array.
It was not as if there were no better places to cultivate.
Not to mention that the Pagoda Ancient Clan had a Saint-Grade Spiritual Array Grandmaster.
The Northern Heavens Spiritual Academy also possessed a Level Eight Spirit Gathering Array.
But for the current Futu Yun, the Level Six Spirit Gathering Array was already sufficient.
Thin mist surged within the array, but it was no ordinary fog. It had condensed from the spiritual energy between heaven and earth.
Normally, this pale spiritual mist formed only when spiritual energy reached a certain concentration, and it was highly beneficial for cultivation.
Plains, mountain streams, and rivers filled the array, making it seem like an isolated paradise.
Quite a few areas had already been occupied by figures.
Although cultivating here consumed a great deal of Spiritual Value, the dense spiritual energy still drew countless students in.
Once they had accumulated enough Spiritual Value, they would flock here to cultivate.
Futu Yun quickly found a suitable spot.
Two enormous peaks met and collided, forming a clear, deep lake whose bottom could not be seen at a glance.
Dense spiritual mist drifted across the lake's surface. Even violent winds could not disperse it.
He stood upon the lake and swept his gaze around—students should have been cultivating secretly around the lake.
Lightning suddenly covered the entire lake, blasting the water into surging waves.
Several students cultivating in the lake were shocked dizzy by the electricity and surfaced.
Though some wore dissatisfied expressions.
When they saw the elders of the Northern Heavens Spiritual Academy repeatedly signaling for silence, those who had been disturbed could only accept their bad luck.
Especially when they saw the lake gradually solidify beneath the lightning, turning into an island, they shrank back and did not dare say another word.
Though they did not know Futu Yun's cultivation level, this ability to alter the terrain was enough to make them wary.
But this was the Northern Heavens Spiritual Academy, so there should not be any danger. Low murmurs thus rose from the surroundings.
Many watched with great interest—cultivation was dull to begin with, and this was a rather nice diversion.
Meanwhile, Futu Yun continued driving the lightning, steadily expanding the island that had appeared from nowhere atop the lake.
When he had absorbed the Netherworld Heart Demon Thunder beneath the Thunder Demon Abyss, he had also devoured quite a bit of Earth Demon Thunder born at the abyss's bottom.
Though he had not broken through to the middle phase of the Divine Soul Stage, it had further tempered his mutated lightning-attributed Divine Soul.
This lightning was extremely special. Though it was lightning power, it could resonate with the earth.
Once activated, it could easily shatter the ground and unleash devastation akin to an earthquake.
Among the five elements, lightning belonged to wood. Water nourished wood, and water could also nourish lightning.
Thus, Futu Yun absorbed the lake water and transformed it into land, creating the island before them.
Just then, a savage dragon roar suddenly resounded through heaven and earth.
Countless shocked gazes followed the sound, only to see a gigantic dragon coiling through the sky amid boundless azure light.
The entire dragon was jade-green. Tiger patterns spread across its azure scales, and instead of a dragon's head, it possessed a ferocious tiger head.
The instant the strange giant dragon appeared, an astonishing fluctuation swept outward.
"That is..." Countless eyes focused. "The Primordial Tiger Jiao ranked fiftieth on the Myriad Beast Record's Earth Ranking?"
Azure light filled the sky.
The astonishing pressure made even the air oppressive.
Countless stunned gazes looked at the azure giant dragon in the heavens, their hearts churning violently.
That was a ferocious existence ranked fiftieth on the Earth Ranking.
Yet the Northern Heavens Spiritual Academy elders watching in secret wore strange expressions.
Most Divine Soul Stage cultivators who could obtain the essence soul of a Primordial Tiger Jiao had powerful backgrounds. It was nearly impossible to acquire one through a chance encounter alone.
But with Futu Yun's status, why would he settle for a mere Earth Ranking spirit beast?
Even if he chose from the Earth Ranking, it should have been a Heaven-Tier Spirit Beast.
Sure enough, the Primordial Tiger Jiao soon ignited itself, as if it were being sacrificed.
It transformed into a snow-white giant tiger that raised its head and roared at the sky.
Endless killing intent swept over the land and sky.
For a time, many onlookers turned ice-cold all over, their spiritual energy intimidated into ceasing its circulation.
