As she stared at the endless waves of bugs which were moving around, devouring everything in their path, Deng Huiling couldn't help but take in a deep breath.

Even though cultivators resisted, with even enemy factions uniting against the common threat as most battles between cultivators ended, this was still not enough.

If a cultivator killed a bug, a new bug would take his place.

If a cultivator killed a thousand bugs, new bugs would take their place.

If a cultivator killed a billion bugs, new bugs would take their place.

No matter how many bugs were killed, the waves of attacks seemingly never ended, allowing even the most powerful of formations to slowly but surely be whittled down to nothing.

Of course, there are, and always will be, a few exceptions.

...

As he stared at the countless waves of bugs that were approaching the Mountain Region, as well as at the defenses that were now being set up by cultivators who had heard of the disaster, Chong Ying couldn't help but shake his head.

Suddenly, Chong Ying's eyes moved to a single corner of the Mountain Region, causing a frown to appear on his face.

"Gao Chun, I didn't expect the betrayer to be you..." mumbled Chong Ying as he stared at the figure lurking behind where the defenses were beings created.

Alongside Chong Ying and Jing Bei, Gao Chun was one of the three False Immortals of the Mountain Region.

But even so, as he stared at the cultivator who he had mentored a long time ago, a look of determination appeared on Chong Ying's face.

"Gao Chun, since you have descended below the level of a human, and betrayed both Humanity and the Three Thousand Regions, let me put you out of your misery," said Chong Yin as an enormous Go board suddenly appeared in front of him.

The moment this Go board appeared, the atmosphere in the entirety of the Mountain subtly shifted.

This shift was extremely obvious to all cultivators in the Mountain Region, but whilst a surprised look appeared on the face of Jing Bei, who was currently killing a wave of bugs that was about to arrive in the Mountain Region, a completely different emotion appeared on Gao Chun's face.

Stolen content warning: this tale belongs on Royal Road. Report any occurrences elsewhere.

Even though Gao Chun was a False Immortal, and extremely powerful, after obtaining the blessing of the Endless Lord, his power grew even further, beyond anything he had even known.

But even so, at this moment, Gao Chun felt extremely powerless as he lost control of his body.

No matter how powerful Gao Chun was, he could not compare to a True Immortal in power, and even if normal True Immortals compared themselves to the might of one of the Three Thousand Regions, they would be outmatched.

Because of this, even though the formation discovered and perfected by Chong Ying was not truly perfect, and could not truly bring out the entire power of the Mountain Region, it was still more than enough.

In but an instant, Gao Chun, as well as any bug or invader that was currently inside the Mountain Region, and it's the closest surroundings, were suddenly annihilated from existence.

The moment that happened, Chong Ying suddenly spat out a mouthful of blood over the enormous Go board in front of him, causing it to undergo another enormous change.

In an instant, an enormous barrier suddenly began growing around the Mountain Region, causing the countless waves of bugs that had desired to enter the region to throw themselves against it, like they do with all formations.

But one cannot compare the power of normal formations to the power of this Immortal Formation created by Chong Ying after countless years.

No matter how many bugs threw themselves against it, or how powerful those bugs actually were, the formation surrounding the Mountain Region stood firm and unmoving under their relentless assault.

Seeing this scene, a faint smile appeared on Chong Ying's face.

As he watched the bugs throw themselves against the formation again and again, Chong Ying knew that things had gone according to plan.

"If none of those beings interfere, this formation should be able to take whatever if thrown at it for an infinite amount of time," mumbled Chong Ying as he felt powerful auras clash throughout the Three Thousand Regions.

Even though he desired to go help with the battle, old man Chong Ying knew his limits very well.

Ever since he had begun cultivating, so many years ago, Chong Ying has never fought a fair battle.

No matter what, Chong Ying would always rely on his formations to do the battling for him, which caused his personal combat prowess to be somewhat disastrous.

Even though he could easily crush Dao Saints and hold his own against normal False Immortals because of his age and sheer raw power, if he actually went up against those beings, Chong Ying would be like a lamb to the slaughter.

Because of this, Chong Ying did not think about going out of the Mountain Region for more than a second.

...

As she watched that enormous Immortal Formation rise around the Mountain Region, Deng Huiling, who was currently controlling the formations of the Origin Sword Sect, couldn't but widen her eyes.

"I see, that Chong Ying discovered and repaired a formation created by an Immortal Formation Master," mumbled Deng Huiling as she as her gaze lingered on the Mountain Region for a few more moments.

Even though the Origin Sword Sect did, in fact, have Immortal Formations, none of them had actually been created by a formation master, as none of the True Immortals of the Origin Sword Sect were actually formation masters.

Rather, each of them used brute force, their immeasurable raw power, as well as their extreme understanding of the Dao to create Immortal Formation.

As such, even though they were all called Immortal Formations, these formations couldn't be compared to the one that had enveloped the Mountain Region.

Of course, this did not mean that they did not have their own advantages.
