He stepped onto the Cultivation Platform in his Immortal Cave.
With a wave of his right hand, Zhang Yuhe sent five small, mystically Qi-infused flags flying around the Cultivation Platform.
He then took out a Formation Plate and gently placed it not far from him.
He took out a large pile of Spirit Stones and placed them around the Formation Flags and the Formation Plate.
After all of this was done.
Zhang Yuhe chanted a spell, and the Five Elements Spirit Gathering Array instantly lit up with points of light.
Endless Spiritual Qi rapidly gathered around him, quickly forming a sea of Spiritual Qi.
Zhang Yuhe sat cross-legged on the Cultivation Platform.
"Let's see if I can deduce the Nine Heavens Primordial Sword Formation."
Thinking about how he had only spent a few days previously to deduce and improve the Ren Water Lightning Absorption Array, he couldn't help but set his sights on the Nine Heavens Primordial Sword Formation.
If he could also improve this Sword Formation, that would be excellent.
The Nine Heavens Primordial Sword Formation was already powerful enough; if it could be improved further, wouldn't that be incredibly amazing?
He thought it, and he did it.
Zhang Yuhe immersed his mind in the Nine Heavens Primordial Sword Formation, and various thoughts continuously appeared in his mind.
However, he quickly opened his eyes and sighed.
"Alas, I was too naive."
After a thorough deduction.
He discovered that the Nine Heavens Primordial Sword Formation was already perfect.
If he were to improve it according to his ideas, it would not only fail to enhance the power of the Sword Formation, but would instead weaken it.
It might even cause chaos, making it impossible to even fully set up the Sword Formation.
"Let's try another one, try deducing the Great Desolate Heaven Imprisoning Finger."
Zhang Yuhe put his mind into the Great Desolate Imprisoning Finger, wanting to improve this Divine Ability.
However, after a long time, he still gave up.
This Divine Ability could also not be improved further.
After some deduction, Zhang Yuhe gained some insights.
Divine Abilities above Heaven Rank were already perfect and could no longer be deduced or improved.
If one forcefully improved them, it would either reduce the inherent power of the Divine Ability or lead to the deduction of a similar new Divine Ability.
That would no longer be an improvement, but a creation.
"It's better to just honestly Cultivate."
After a few attempts, Zhang Yuhe quickly gave up on the idea of continuing to deduce Divine Abilities.
He wasn't the only Genius.
Those who could create Heaven Rank Divine Abilities were all Super Geniuses.
Every Heaven Rank Divine Ability had already been deduced to its extreme.
It was already beyond improvement.
...
As the Primal Heaven slowly circulated, the surrounding sea of Spiritual Qi rapidly converged into his Dantian.
The Spiritual Qi sea in his Dantian churned with waves, and the purity of his magic power increased slightly.
"It still seems a bit slow."
Feeling the Spiritual Qi rapidly converging into his Dantian, Zhang Yuhe silently calculated.
Even if he Cultivated every day without interruption, it might take twenty to thirty years to Cultivate to the Void Refining Middle Stage.
One must know, this was with the acceleration effect of the Five Elements Spirit Gathering Array activated.
The second-level Five Elements Spirit Gathering Array could increase Cultivation speed by two times.
Without the Five Elements Spirit Gathering Array, it might take several decades to Breakthrough to the Void Refining Middle Stage.
"No wonder Lu Mingfang said that some Elders in the Sect had made no progress in their Cultivation for thousands of years."
Such slow Cultivation progress indeed easily led to despair.
Even with his Heaven-Defying Aptitude, the Cultivation speed was uncomfortably slow.
How much harder must it be for others?
Perhaps after several hundred years of continuous Cultivation, there might still be no progress at all.
How could one bear that?
"Alas, the Dao of Cultivation truly tests one's patience."
No need to panic, slowly.
Zhang Yuhe quickly shook off all his random thoughts and fully immersed himself in Cultivation.
...
On a deserted small island in the Tianxing Sea.
A beautiful and graceful woman walked slowly on the small island, holding a Formation Plate in her hand.
As the woman walked slowly, she rapidly chanted spells.
Behind her, several Black Shadows with monstrous Demonic Qi followed.
One of the Black Shadows seemed a bit impatient and complained with a slightly resentful tone.
"Moonlight Sect Master, are you sure you're not mistaken? Is this a spatially weak area? Can it open a fixed passage connected to the Saint Realm?"
Hearing the Demon Shadow's complaint, the woman smiled and turned her head, her smile blooming like peach blossoms, intoxicatingly beautiful.
However, the Black Shadows behind her seemed to ignore it.
In their eyes, the beautiful woman was not even as good as a plate of meat on the dining table.
The beautiful woman smiled and said, "Black Demon Lord, don't rush. Since I came here personally, I naturally have some confidence."
"Some time ago, my Incarnation passed through this area and saw intense spatial fluctuations here."
"Lord, you also know that the Yu Fan Heaven space is stable and would not fluctuate without reason."
"From this, I judge that the space here should be weaker. Perhaps a great battle occurred in a nearby world, and the aftershocks of the battle transmitted and shook the spatial barrier here."
After hearing the beautiful woman's explanation, the Black Shadow's eyes instantly lit up.
"Oh, the world adjacent to Yu Fan Heaven is only the Saint Realm. So, opening a space here means it's very likely a fixed passage."
The beautiful woman was precisely the Demon Sect Master, Zhao Mingyue.
In order to find a solution to the incomplete Divine Soul aftermath caused by her Myriad Incarnations Divine Ability.
She had tried every possible method, but still could not solve the problem.
Later, she heard that the Demon God Palace in the Demon Realm could communicate with the Upper Realm.
The Demon Gods in the Upper Realm were equivalent to True Immortals, and they would surely have a way to solve her problem.
In fact, the Dao Saint Sect could also communicate with the Upper Realm before, but she could not go to the Dao Saint Sect.
That would only be sending herself to her death.
She had been fighting with the Dao Saint Sect for so many years; both sides were already in a life-or-death situation.
Wanting the Dao Saint Sect to help was undoubtedly a pipe dream.
Zhao Mingyue was eager to open a spatial passage.
This way, she could not only allow the Demon Race to enter Yu Fan Heaven and destroy the Dao Saint Sect, settling her years of enmity, but she could also take this opportunity to enter the Demon Realm and have the Demon God Palace help her contact the Upper Realm to seek a solution to her problem.
Although she knew that doing so was like playing with fire, she had no other choice.
Stuck at Body Integration Great Perfection for nearly ten thousand years, Zhao Mingyue could no longer wait.
If she delayed any further, as her body aged, she would no longer be able to Breakthrough to the Mahayana Realm.
To open the passage between the two realms, Zhao Mingyue actively contacted the remaining Demon Race in Yu Fan Heaven.
With their cooperation, they tried various actions.
For example, setting up the Tiangang Breaking Boundary Great Formation in Mirror Void City was one such attempt.
However, these attempts later ended in failure.
The Yu Fan Heaven space was stable, and relying solely on the Tiangang Breaking Boundary Great Formation could only open a temporary passage.
Moreover, the passage was unstable and could only support Demon Race below Nascent Soul to pass through.
To allow the Mahayana Demon Race from the Demon God Palace to come, a fixed passage had to be opened.
Just like the passage the Demon Race opened a hundred thousand years ago.
Unfortunately, that passage was located in the Dao Saint Sect's back mountain and was guarded by Mahayana Cultivators.
Even though Zhao Mingyue used every means possible, she still couldn't find an opportunity to sneak in.
