In Fang Yuan's hands, he held the Heavenly Jealousy Immortal Gu.
Under the continuous infusion of Eighth Transformation White Lychee Immortal Essence, the Heavenly Jealousy Immortal Gu radiated a faint, crystal-like brilliance.
The Immortal Gu itself resembled a crystal flea, fist-sized, curled up in a ball.
Suddenly, the crystal radiance on the Heavenly Jealousy Immortal Gu's body exploded, shattering into countless tiny crystalline sparks, dazzlingly brilliant!
"Success!" Fang Yuan's heart stirred slightly. In that brief instant, this Seventh Transformation Heavenly Jealousy Immortal Gu had been completely refined by him.
The crystal flea, previously curled into a ball, now fully unfurled its body, lying with perfect suppleness in Fang Yuan's palm.
"I'm probably the first person in all of history to completely refine the Heavenly Jealousy Immortal Gu."
In this moment, Fang Yuan had made history!
But in the next instant, the joy in his heart settled back down.
Making history was something he had done many times before.
"Lately, I've been making repeated moves to help my subordinate Gu Immortals undergo tribulation and ascend. Although each tribulation yields relatively few Heavenly Dao marks, they accumulate over time."
"These accumulated Heavenly Dao marks finally allowed me to completely refine the Heavenly Jealousy Immortal Gu, breaking through the previous limit."
"My earlier speculation was indeed correct!"
The facts before him had proven it: as long as one's Freedom Heavenly Marks reached a sufficient level, it was possible to refine a Heavenly Dao Immortal Gu.
Throughout history, there had been countless Gu cultivators, among whom the elite were like stars filling the sky, the ten Venerables shining like ten blazing suns. But none of these figures had truly cultivated the Heavenly Dao.
Wuji Demonic Venerable and Letu Immortal Venerable had both grasped the Freedom Heavenly Marks Killer Move, but as far as Fang Yuan knew, neither had delved deeply into the Heavenly Dao.
The former specialized in Rule Dao, the latter in Earth Dao. Perhaps Wuji Demonic Venerable had developed the Freedom Heavenly Marks Killer Move and considered switching to the Heavenly Dao, but by then he had already become a Demonic Venerable of Rule Dao and could never turn back.
From this, one could once again see the advantage of the Supreme Immortal Aperture Gu.
Mastery of all paths!
An entirely new, uncharted road now revealed itself before Fang Yuan.
The Heavenly Dao!
The Freedom Heavenly Marks Killer Move was the crucial key to unlocking Heavenly Dao cultivation.
The vast prospects and terrifying advantages of this cultivation path—even an ordinary person could grasp a hint of them!
"The Heavenly Dao encompasses all things, balances all things. Every living being, immortal or mortal, high or low, falls within the Heavenly Dao's embrace. All manner of Immortal Gu, Heaven and Earth Secret Realms, are likewise kept in check by the Heavenly Dao. The Heavenly Dao governs tribulations, controls Lifespan Gu. A Venerable may dominate an entire great era, but compared to the Heavenly Dao, they are merely a single blazing torch."
"If I were to walk this path..."
Fang Yuan couldn't help but drift into reverie.
Setting everything else aside, just the two factors of Lifespan Gu and Fate Gu alone made him feel a faint thrill of excitement.
Every generation of Venerables had been plagued by Lifespan Gu, and the Heavenly Court had never truly gained direct control over Fate Gu. Even Star Constellation Immortal Venerable had been powerless, ultimately forced to merge herself with the Dao to interfere with Heavenly Will and distort the effects of Fate Gu.
"Among all the paths, the Heavenly Dao's threshold for beginning cultivation is undoubtedly the highest. One must first master the Freedom Heavenly Marks Killer Move."
"I've only just set foot on the path of the Heavenly Dao, and I still need to travel a very long distance before I can touch upon the profound mysteries of Lifespan Gu and Fate Gu!"
"The battle at Mad Demon Cave is approaching, and at the very least, I won't make it in time before then."
Although he had officially embarked on the path of Heavenly Dao cultivation, and its prospects were undeniably bright and vast, Fang Yuan did not intend to devote himself to it fully.
The situation simply didn't allow it.
"At most, I'll invest one more time at the key point of the Heavenly Jealousy Immortal Gu."
The Luck Boiling Pot had given Fang Yuan tremendous convenience, letting him know that the Heavenly Jealousy Immortal Gu might be the key to the battle at Mad Demon Cave.
The path of Heavenly Dao cultivation would be long, and Fang Yuan had only just begun. But the Heavenly Jealousy Immortal Gu could be developed as a priority.
"Even though I've now completely refined the Heavenly Jealousy Immortal Gu, it's still only at the Seventh Transformation. Even if I developed a Killer Move that could perform at the Eighth Transformation level, when I face a Venerable in battle, the Seventh Transformation level would still be somewhat lacking."
"I need to upgrade the Heavenly Jealousy Immortal Gu to the Eighth Transformation!"
Fang Yuan had the Four Origin Fanghui Blood Refinement Pool in his possession, but this time there was a slight complication.
In terms of Heavenly Dao immortal materials, Fang Yuan still had a stockpile. Investing in many other Heavenly Dao Immortal Gu might pose difficulties, but focusing solely on the Heavenly Jealousy Immortal Gu was still feasible.
However, Fang Yuan's Heavenly Dao realm was rather ordinary—he hadn't even reached the Master level. Although his Refinement Dao realm was at the Quasi-Supreme level, developing an Eighth Transformation immortal Gu recipe for the Heavenly Jealousy Immortal Gu was still very difficult.
It wasn't that success was impossible, but the time and effort required were simply too great.
A preliminary estimate suggested at least two to three years of calculation time.
For Fang Yuan, this was clearly unacceptable.
"It seems I'll need to learn from Wu Yong and cultivate some Gu Immortal seeds, helping them undergo tribulation." Fang Yuan quickly found his solution.
When a Fifth Transformation Gu Master ascended through tribulation, the Heavenly Dao mark gains were extremely meager—Fang Yuan wouldn't even look at them. But the moment a Gu Master underwent tribulation, there was always a peerless opportunity to emulate Nature.
During this opportunity, when a Gu Master questioned Heaven and Earth, virtually every question could receive an answer.
Since Heaven and Earth could naturally produce the Heavenly Jealousy Immortal Gu, they must necessarily possess the recipe for it.
Fang Yuan didn't need much—just one correct Heavenly Jealousy Immortal Gu recipe, and he could rely on his Refinement Dao expertise to continuously improve and adapt it to his own needs.
Moreover, Fang Yuan could be clever about the way he questioned Heaven and Earth.
