Since the creator never gave it a name, Fang Yuan tentatively called it: the Rebirth Method of Living and Death Immortal Orifices.
The value of this method was absolutely immeasurable!
Once it spread, it would undoubtedly shake the entire cultivation world and reshape the balance of power across the land. Countless Immortal Gu Masters—whether reclusive hermits or Eighth Transformation powerhouses—would immediately devote themselves to studying it and begin practicing it.
Once the majority of Immortal Gu Masters truly mastered it, the number of Immortal Gu Masters across the five regions would surge dramatically, ushering in an unprecedented golden age.
Because the Life and Death Immortal Orifice contained the profound essence of life and death, it could reduce the power of heavenly tribulations and earthly calamities. And the reduction amounted to a full fifty percent!
What did that mean?
Immortal Gu Masters had always faced two great obstacles in their cultivation.
One was lifespan. The other was calamity.
Higher cultivation did not extend one's lifespan—Immortal Gu Masters could only seek other methods, employing every means at their disposal to prolong their time of survival.
But that was beside the point.
The real focus was on calamity.
At regular intervals, every Immortal Gu Master had to endure tribulations. Heavenly tribulations and earthly calamities hung like executioner's blades above their heads.
In peacetime, the vast majority of Immortal Gu Masters perished due to calamity. Countless historical records and real-life examples served as constant reminders of how terrifying and lethal this threat truly was!
Calamity was not only difficult to predict, but its power was not constant—it gradually intensified with each cycle.
To survive tribulation, an Immortal Gu Master had to drive themselves to cultivate harder and constantly grow stronger.
But cultivation was no empty talk—it demanded real, tangible resources. Such as immortal materials, Immortal Gu, Immortal Path killer moves, and Immortal Gu houses.
The immortal aperture was the best place to cultivate immortal materials.
Because the environment inside was unique. It contained abundant Dao marks and could grow materials suited to the Immortal Gu Master's specific needs based on their individual conditions. Moreover, time inside the immortal aperture flowed much faster than in the five regions, meaning immortal materials matured more frequently and could be harvested more often.
There was one more advantage to cultivating resources inside the immortal aperture. It was more convenient for transport and far safer.
Keeping resources outside was far too dangerous.
Not only could they easily be seized or plundered, but when facing powerful individuals like the Burning Heaven Demon Girl, if they couldn't take them, they could simply destroy them.
However, every single heavenly tribulation and earthly calamity dealt enormous negative damage to the immortal aperture.
Merely surviving the calamity was already difficult enough. Trying to preserve the immortal aperture at the same time was nearly impossible.
The cultivation resources stored within the immortal aperture would often suffer devastating losses.
For an Immortal Gu Master to continue cultivating, they would need to accumulate resources all over again—and in the worst cases, they practically had to start from scratch.
This created a vicious cycle.
Accumulate resources, cultivate, grow stronger, endure tribulation… then re-accumulate resources, cultivate again, grow slowly stronger, endure an even more powerful tribulation…
The calamity grew heavier and heavier, but the need to re-accumulate resources severely hampered the speed of an Immortal Gu Master's growth. Many found their strength stagnating or barely improving. How could they possibly cope with ever more fearsome tribulations?
This was why, throughout the ages, countless Immortal Gu Masters had been defeated by heavenly tribulations and earthly calamities. Their bodies perished and their Dao was extinguished.
The Fox Immortal was a prime example.
She had survived the first four calamities, but during the fifth, she encountered the Enchanting Blue Lightning and was killed. Her lingering obsession gave birth to a land spirit, leaving behind the Fox Immortal's Blessed Land, which ultimately fell into Fang Yuan's hands.
Of course, there was one approach: transferring cultivation resources out of the aperture beforehand.
That was what Fang Yuan had done previously.
But in truth, very few Immortal Gu Masters actually did this.
They were no fools. So why not?
The reason was that tribulations were targeted. For example, suppose a Wood Path Immortal Gu Master moved all of his Wood Path resources out before tribulation—only to attract a Fire Path calamity instead.
After surviving the tribulation, the immortal aperture suffered enormous changes, gaining numerous Fire Path Dao marks. The terrain and temperature shifted drastically.
When the Wood Path Immortal Gu Master tried to move his original cultivation resources back in, many of them could no longer adapt to the new aperture environment and simply could not be cultivated at all.
Conversely, if the Wood Path resources were left inside the blessed land and a Wood Path calamity was attracted instead, then after the tribulation the aperture would gain more Wood Path Dao marks. Although the resource losses would be heavy, the aperture environment would actually become more favorable.
Countless cases—both successes and failures—along with the accumulated wisdom of predecessors all pointed to one conclusion: keeping resources inside to endure tribulation was wiser and more beneficial to an Immortal Gu Master's cultivation than moving them out beforehand.
Fang Yuan had moved his resources out previously, but what he attracted was a Blood Path calamity, which did nothing to benefit the cultivation of his original resources.
However, the Fox Immortal's Blessed Land had not been well-suited to his path, so the gap had not been significant.
After that, Tai Bai Yun Sheng—despite knowing the resource losses would be enormous—still chose to leave his resources in his immortal aperture during tribulation. That was because the blessed land he used for tribulation was his root immortal aperture.
Only by understanding all of the above could one truly grasp the terrifying value of the Life and Death Immortal Orifice!
Immortal Gu Masters may stand at the apex, but with calamity looming overhead, they had to cultivate ceaselessly. At every stage they needed to make dramatic leaps in progress—greater leaps each time than the last—just to keep surviving.
But with the Life and Death Immortal Orifice, everything changed.
The power of calamity was directly reduced by fifty percent!
With the calamity's power slashed, losses to cultivation resources dropped sharply. The Dao mark gains remained unchanged. All of this was enough to transform an Immortal Gu Master's cultivation into a virtuous cycle.
Accumulate resources, cultivate, grow stronger, endure tribulation… then on that existing foundation, accumulate resources faster, cultivate more rapidly, grow in strength at a dizzying pace, endure a slightly stronger tribulation…
With only a living aperture, the calamity's power kept escalating, and the Immortal Gu Master barely held on. The higher their cultivation, the harder each step became.
With only a dead aperture, the aperture kept collapsing, resources could never be re-accumulated, and there was no hope of progress. It was a fate worse than death.
But with the Life and Death Immortal Orifice, a virtuous cycle was established. The Immortal Gu Master's strength would snowball, growing larger and larger with each turn, and surviving tribulation would become more and more certain!
Without question, this was an achievement that transcended eras!
It could transform the world of Immortal Gu Masters, reshape the entire world, and rewrite the future history of Gu Masters.
It might seem like a small rebirth technique, but it possessed exactly this kind of magical power!
More precisely, it was no longer a simple rebirth method—it was a cultivation method.
Building upon its original foundation and further refined, it was undoubtedly superior to the traditional cultivation methods that had been passed down through countless ages!
This kind of breakthrough could be likened, in terms of Earth's history of development, to the invention of the steam engine, the harnessing of electricity, or the creation of the computer!
Traditional Gu Master cultivation methods had been handed down since the era of the Human Ancestor, virtually unchanged for all of recorded history.
The emergence of the Rebirth Method of Living and Death Immortal Orifices was like Einstein proposing the general theory of relativity on Earth—overturning Newton's first law!
For other Immortal Gu Masters, this might be difficult to accept at first. They might even dismiss it as a pipe dream or heresy!
After all, Immortal Zombies were lowly in status, yet this method venerated the dead immortal aperture.
But Fang Yuan's fundamental soul came from Earth. His thinking was open-minded, and traditional cultivation methods had never taken root as an unshakable authority in his mind.
