The Mountain Ancestor stood suspended in the void, his originally pure and flawless full-moon immortal body now tainted by black water.

Black water clung to his immortal body from head to toe, completely enveloping it, and was still bubbling away.

A terrifying scream of pain emanated from the black water, followed by an endless surge of immortal power erupting from the Mountain Ancestor's body.

The black water covering him was forced away from his immortal body in an instant.

"Damn it, damn it, damn it... Ugh!"

At this moment, the Mountain Ancestor seemed to be a mortal who had accidentally entered an insect cave, and was suddenly covered by a sky full of terrifying insects, so his reaction was naturally similar.

Compared to insects, this black water is undoubtedly far more terrifying.

Not only was there a nauseating odor that he couldn't block out, but it was also unbearable for the Mountain Ancestor's immortal body, like an ordinary person being thrown into a cesspool.

It still retains the characteristics of a twisted monster and wants to devour and transform the mountain ancestor.

Just like when Ning Qi first fought the twisted monsters, those twisted monsters devoured the cultivators of the Mountain and Sea Realm and transformed them into even stronger beings.

The Mountain Ancestor kept leaping and shifting in the Boundary Sea, as if only by doing so could he shake off the black water splashed on him and incidentally alleviate his intense emotions.

Ning Qi quietly stared at the mountain ancestor who was jumping around.

The mountain ancestor's body shimmered with light, every strand containing terrifying immortal power.

However, he was unable to completely drive away the black water; he only managed to remove most of it.

From a distance, Shanzu Mountain now looks like a piece of pure, flawless jade, now stained with black spots of varying sizes.

Black spots appeared on the Mountain Ancestor's pure and flawless immortal body, making him look as if he had contracted some kind of strange skin disease.

Ning Qi observed carefully and found that the black spots on the mountain ancestor's body varied in color, but they were undoubtedly wriggling on its body.

Some resembled scabies, some black moles, and some skin diseases, exuding a corrupting power, constantly invading and taking root into the immortal body of the Mountain Ancestor...

This black water is the residual energy left after the twisted monster was killed by the Mountain Ancestor, and it needs to be refined with immortal fire to completely disappear.

However, the boundless evil energy secretly manipulated the immortal fire, pouring it completely onto the Mountain Ancestor's immortal body.

The Mountain Ancestor never expected his immortal fire to go out of control, and even now, he still doesn't understand how it happened.

He even thought at one point that the accident was caused by him gathering the black water together and burning too much of it.

After all, Shan Zu simply couldn't believe that Ning Qi was capable of doing this.

Since becoming an immortal, Ning Qi has not even dared to appear in front of him in his true form. How could he do such a thing?

The Mountain Ancestor continuously released the immortal power within his body, desperately trying to remove the black spots from his skin.

Ahead, he had also killed the last twisted monster, but the remaining black water was still there.

Although there seemed to be no enemies left on the scene, the boundless evil energy had not yet made its move.

I have to say, the boundless evil energy is absolutely terrifying!

Besides being immeasurable, what makes it even more terrifying is that it possesses its own will.

It can be said that apart from forcing it to attack the Mountain Ancestor, everything else was its own choice, and Ning Qi did not interfere at all.

Apart from Ning Qi, the Mountain Ancestor did not discover the existence of the Boundless Evil Qi.

The boundless evil energy was like a killer who knew best how to lie in wait; it dispersed and completely merged into the immortal light emanating from the Mountain Ancestor.

Silver light emanated from the Mountain Ancestor's body, continuously impacting the black spots on his skin.

Ning Qi sensed that boundless evil energy was also rushing towards the black spot.

And so the following scene unfolded.

I could clearly see that the mountain ancestor's divine light could knock away those terrible black spots, but the boundless evil energy was like a wicked old man deliberately causing trouble.

When it comes into contact with dark spots, it can actually cause dark spots to grow!

It looked as if the black spots had launched a fierce resistance due to the impact of the mountain ancestor, and thus the black spots on the mountain ancestor's body slowly became larger and darker.

Upon seeing this, the Mountain Ancestor nearly fainted from anger.

A surge of even stronger divine power erupted from within him, determined to completely eradicate the black spots.

In this tug-of-war situation, the sixth brother, Wuliang Xieqi, was still absorbing the immortal power of the Mountain Ancestor, leaving Ning Qi, who was watching from afar, speechless.

"Becoming an immortal doesn't seem to make one completely invincible; on the contrary, it amplifies certain weaknesses."

Ning Qi secretly thought.

It can be said that when Ning Qi first met the Mountain Ancestor who had become an immortal, he even felt a sense of suffocation.

The mountain ancestor's immortal body was so pure and flawless, and its immortal power surpassed all the power within Ning Qi's own body, reaching perfection in quality.

Ning Qidu doesn't want to fight Shan Zu for the time being.

However, after becoming an immortal, the Mountain Ancestor clearly became extremely sensitive to the entire Boundary Sea.

He loathed Jiehai, which gave Ning Qi an opportunity to attack him.

The twisted monsters that came from the depths of the Boundary Sea forced the Mountain Ancestor to abandon the search for Ning Qi and the others and eliminate them as soon as possible.

As for the final move by the boundless evil energy, it instantly triggered the Mountain Ancestor's reaction, causing him to jump up and down in the Boundary Sea.

For some reason, seeing this scene made Ning Qi feel more and more that becoming an immortal might not be a good thing.

At least, Ning Shanzu's path to immortality through traditional cultivation methods seems ill-suited to the current situation.

This made Ning Qi determined that he must continue to pursue his own path to immortality as a Realm Lord, rather than the path of becoming an immortal as a Mountain Ancestor.

"Let's do it!"

Ning Qi gave another order to the boundless evil energy.

Boundless evil energy clung to the surface of the Mountain Ancestor's immortal body, moving about unwillingly.

Ning Qi sensed that it was like a layer of energy veil, gradually spreading out and enveloping the immortal body of the Mountain Ancestor.

Even at such close range, it was still able to remain undetected by the Mountain Ancestor, which made Ning Qi even more wary of it.

This thing was kept so secret even from a mountain ancestor as powerful as it is; thankfully, it wasn't this powerful when Ning Qi first encountered it.

Despite the radiant immortal light emanating from the mountain ancestor, it was still unable to completely dispel the black spots from its immortal body.

A fierce glint flashed in his immortal eyes, his internal organs glowed, and he actually spat out a Five Elements Immortal Talisman.

"Five Elements Primordial Immortal Thunder Talisman!"

The five elements flowed on the talisman, giving rise to an incomparably dazzling bolt of lightning.

Sizzle!

The talisman flashed and struck the black spots on the mountain ancestor's body.

It's like a custom-made electric knife, not harming the pure immortal body of the Mountain Ancestor in the slightest, but specifically targeting the parts with black spots.

In an instant, wherever the lightning passed, all the black spots were swept off like dried scabs, and then completely shattered by the lightning.

In just a short while, the Mountain Ancestor's immortal body was covered with pits and corrosion holes.

Fortunately, he was extremely decisive, even at the cost of his own immortal energy, to eliminate it. Otherwise, the black spot would likely have corroded his immortal body even more severely.

The dark spots disappeared, and the Mountain Ancestor Immortal regained his radiance, illuminating the boundary sea.

He breathed a sigh of relief and looked around.

"Ning Qi, let's see what other tricks you have up your sleeve now!"

Strands of celestial light began to repair the pits on the surface of the Mountain Ancestor's body, and continued to spread, forcing back the energy of the surrounding sea.

The Mountain Ancestor's eyes swept across the area, but he did not find any trace of Ning Qi.

He was not impatient about this.

Ning Qi hid to the side, using every means to shield his aura fluctuations.

Suddenly, he saw the mountain ancestor's heartbeat.

The mountain-shaped seal, symbolizing the lineage of immortals from Mount Buzhou, was twisting and subtly transforming into a heavenly eye.

Within the Heavenly Eye, triangular runes rotated, gradually forming a divine pupil.

Looking at that celestial eye, Ning Qi couldn't help but feel a sense of unease.

He dared not gamble on whether he could remain undetected by that eye, and Ning Qi even had a fleeting thought of teleporting back to the True Martial Spirit Realm.

After the Mountain Ancestor became an immortal, the power that previously separated immortals and mortals and blocked time and space disappeared in the Boundary Sea.

Therefore, Ning Qi knew that he could instantly teleport back to the True Martial Spirit Realm.

Even the Holy Ancestor and the Sea Ancestor, whom he exiled to the Blackwater District of the Boundary Sea, have returned to the True Martial Spirit Realm using the nameplates he gave them.

However, when Ning Qi looked at the mountain ancestor in front of him, he felt his blood boiling.

He didn't want to run away, and besides, could he really escape by running away?

Ning Qi released another boundless evil energy from his fingertips, and the various powers within his body gradually merged into one.

True Martial Realm Power, Mountain and Sea Realm Power, Vast and Righteous Realm Power, various powers cultivated through reincarnation, and the energy of the Realm Sea...

Of course, Ning Qi dared not let this boundless evil energy enter his body.

With the example of the Sword Ancestor before him, who had been plagued by evil energy for ten thousand years, Ning Qi would not take the risk.

The evil energy spread out and enveloped him.

The mountain ancestor's inner eye began to pulsate, scanning along the boundary sea.

Just as he was about to fire at Ning Qi's location, the boundless evil energy that was infused with immortal light on the Mountain Ancestor's body finally made its move!

The evil energy immediately absorbed all the divine light emanating from the Mountain Ancestor's body. It looked as if the Mountain Ancestor, like a bright light bulb, had suddenly gone out without warning.

"What happened?"

The Mountain Ancestor's attention was focused on the Boundary Sea, but the immortal light on his body suddenly disappeared, which greatly alarmed him!

All the energy from the boundary sea that had been driven away surged towards him like a tide.

In the next instant, boundless evil energy actually burrowed into the immortal body through the pores and seven orifices of the mountain ancestor.

In an instant, the Mountain Ancestor collapsed into the Boundary Sea.

Ning Qi was about to make a move, but stopped immediately upon seeing the Mountain Ancestor.

Why is my immortal power beyond my control? What is stealing my immortal power?

At this moment, the Mountain Ancestor could only release a layer of humanoid immortal light, and could no longer release the full moon-like halo.

He felt as if something else was robbing him of control over the power within him.

"Did you do this again, Ning Qi?"

The mountain ancestor was filled with boundless hatred; where was the sacred image of a transcendent immortal?

He directly linked his own changes to Ning Qi.

Ning Qi silently sensed the boundless evil energy, and he was still able to maintain a connection with the boundless evil energy that had invaded the Mountain Ancestor's body.

It could be said that he was experiencing the attack of the Mountain Ancestor by the boundless evil energy from a third-person perspective.

The boundless evil energy entered the Mountain Ancestor's body and instantly occupied various acupoints, especially the three key areas: the forehead, heart, and dantian.

Immediately upon entering, it began to seize the immortal power within the Mountain Ancestor's body, vying for control of him.

Even from a third-party perspective, Ning Qi was taken aback by the sheer ferocity of the evil aura.

It's likely that when the Sword Ancestor was poisoned by this evil energy, he also went through this process at the beginning, only that both were very weak back then.

The evil energy ran rampant, like the most terrifying predator in the Boundary Sea, and took the immortal body of the Mountain Ancestor as its prey.

While absorbing the power of the Mountain Ancestor, seizing control, and causing damage within the Mountain Ancestor's body, the effects were quite remarkable.

The mountain ancestor's immortal body flickered between light and shadow, barely managing to maintain its immortal radiance and resist the invading energy of the boundary sea.

Ning Qi narrowed his eyes slightly.

"Even now, he is still resisting the energy of the Boundary Sea. Is his immortal body so resistant to the energy of the Boundary Sea that he is unwilling to stay in the Boundary Sea?"

Ning Qi quietly approached the Mountain Ancestor.

Since making his first statement, Shan Zu has been completely absorbed by the changes within his body.

The situation within his body terrified him, but gradually, he also managed to deduce what was going on from the inheritance within his mind.

"Damn it, this is boundless evil energy! Ning Qi, you'll die a horrible death for using something like this against me!"

The mountain ancestor was practically cursing.

He became an immortal overnight and considered himself invincible, but as soon as he emerged from seclusion, he encountered such a series of setbacks.

He felt like the most aggrieved immortal in history!

But unfortunately, he had no solution.

Because this is the world we live in now.

The world is barely resisting the invasion of the Boundary Sea, and there are very few immortals in the entire Spirit Realm.

Even the collapse of Mount Buzhou in the past was related to changes in the boundary sea.

The energy of the Boundary Sea is not only eroding all the worlds within it, but also the Immortal Realm!

In the past, once cultivators achieved immortality, they could shatter the void and fly directly to the immortal realm.

However, after the appearance of the Boundary Sea, the fairyland shattered and split into several pieces.

Even though someone like Shan Zu, who has become an immortal, has been recognized by the immortal sect and registered in the immortal register, he still has to cross the Boundary Sea and go to those realms before he can truly leave the Boundary Sea and enter the immortal realm.

Therefore, these immortals regard the energy of the Boundary Sea and the twisted monsters within it as the most filthy things in the world.

But the boundless evil energy in the heart of the Mountain Ancestor was even more terrifying than the former two.

According to what he passed down and the messages from the immortal sect when he became an immortal, the boundless evil energy may be the root cause of the changes in the Boundary Sea!

They once mentioned that the boundless evil energy was extremely wicked!

As the Mountain Ancestor sensed the condition within his body, he felt that only the legendary boundless evil energy could have tormented a mere immortal like him to this extent.

The only thing he could be thankful for was that the amount of the boundless evil energy was very small.

After seeing through everything, the Mountain Ancestor suddenly clasped his hands together.

"There's no other way. Only by staying alive can one become an immortal. Staying alive is the most important thing!"

Upon seeing his posture, Ning Qi stopped warily.

The Mountain Ancestor suddenly shouted, "The remnants of the mountains embrace the sea!"

Rumble!

A tremendous roar erupted from within the Mountain Ancestor's body, and at that moment, the Mountain Ancestor's immortal body seemed to become semi-transparent.

A mountain shadow reappeared from the Mountain Ancestor's body, slowly enlarging until it completely enveloped his immortal body.

The illusory image of the remaining mountain, resembling an eternal and indestructible divine mountain, stands in the boundary sea, sealing the immortal body of the mountain ancestor.

The mountain-shaped mark on the forehead of the Mountain Ancestor was restored and kept flashing, as if echoing the released mountain shadow.

"The remains of Mount Buzhou?"

Ning Qi frowned slightly, wondering why the Mountain Ancestor had summoned the remnants of Mount Buzhou that he had previously devoured.

The reappearance of the dark mountain shadows brought Ning Qi a distinctly different feeling.

Its entire body was as black as ink, yet it exuded an aura of unparalleled holiness and an unapproachable majesty. (End of Chapter)
