The true Sea in the Mountain had finally appeared!

However, while the seawater seemed clear and transparent, it was actually a nightmarish killing weapon. The slightest contact would reduce one's flesh to pulp.

Any great void immortal treasure level armor would be eaten away.

Just as Wu Yu was at wits' end, suddenly the Sea in the Mountain changed again!

He had just gotten his footing as he appeared above the glowing rectangle.

Suddenly-

The rectangular glowing object might well be a portal of which he had never seen the likes of before. There was a terrible aura coming from within.

Wu Yu could currently feel the horrific aura within.

Sensing impending danger, and the prospect that something huge was about to appear below, he flew up into the sky, at the same time using Fulgurating Shadows, dodging the threat which might soon appear!

"What is this!"

After fleeing the danger zone, the seawaters below continued to froth and churn, creating powerful waves that reached the sky.

Amidst the terrifying currents, the awakened monster had already appeared before Wu Yu's eyes.

It was a pure black whale, covered with sickly white spots. Its red eyes were like two blood-red moons, gleaming in a malevolent way that hid its true thoughts!

"Demon immortal? No."

It was rare to see such a huge beast in the sky palaces.

Ordinarily, immortal beasts such as mystical dragons and phoenixes were bursting with immortal qi, and only had a slightly stronger bestial aura compared to immortals.

However, demon immortals were completely different. The overpowering demonic aura could completely swamp one's immortal qi. The difference between demon immortals and immortal beasts was larger than the difference between immortal beasts and immortals.

Although immortal beasts were also a type of demon immortal.

The difference between ghostly immortals and immortals was like the difference between demon immortals and immortal beasts.

Wu Yu had never seen a true demon immortal for a long time, besides Jiu Ying.

From the start, the whale had emanated a robust demonic aura that had filled the entire Ancient Demon Realm.

Perhaps everyone throughout Ancient Demon Realm would have felt this uncomfortable and violent demonic aura.

However, he soon realized that this "demon immortal" was not alive. Although it seemed to have a crushing aura, but it was not a living thing.

"It must be a corpse puppet! Ghostly immortals often create such corpse puppets. They use the corpses of demon immortals, and retain a portion of the demon immortal's former strength. However, it has no sentience, and can only be used as a war machine for specialized missions." Ye Xixi hurriedly offered.

Corpse puppets, Wu Yu had seen before. They were similar to puppets and mechanical beasts - revolving around some special immortal design. Corpse puppets used strong bodies, and the remnants of immortal, ghostly, or demonic spirits sealed in through a special way, while puppets used specialized precious treasures.

Because corpse puppets were the corpses of powerful beings, if power decay was not too serious, they might actually be even stronger.

"Ordinarily, corpse puppets would see their corpses age and rigidify. But this black whale seems fresh, as if it had just died yesterday. No wonder we thought it was a demon immortal at first." Full Moon of Nanshan observed.

Wu Yu had also noted how fresh the death seemed.

He said suspiciously: "It has been here for so long - it can't be a freshly dead demon immortal. There must have been some special method used to preserve the corpse's freshness, and therefore its optimal fighting power."

Just how fresh was this corpse?

Wu Yu's Heaven Devouring Titanic Beast could only devour fresh corpses for it to be effective, and this black whale was so fresh that it would probably be devourable.

However, this demon immortal had definitely been dead for tens of thousands of years.

Therefore, this was a difficult puzzle for them to solve.

However, there wasn't much time for them to solve it either, because the black whale corpse puppet had already homed in on them. As the guardian here, the black whale's job was clearly to deal with intruders like Wu Yu!

"Watch out!"

In the next instant, the black whale had attacked.

It was not only terrifying as of itself, but could also call upon the Mountain in the Sea!

Tidal waves surged around its body, while it remained completely unaffected.

The spraying waters would cause many troubles for Wu Yu and the others.

Luckily, they did not lose their orientation, and could still retreat.

Without another word, he first fled. Currently, he still did not know what the black whale was capable of!

Besides, he guessed that the Mountain in the Sea's position was fixed. Without these waters, perhaps the black whale would be easier to deal with.

Time to see if it would follow him out.

Splash!

As expected, the black whale surged out of the waters, giving chase as Wu Yu fled.

It bellowed, a terrifying sound that shook the entire Ancient Demon Realm.

The roar made seas and mountains tremble, and the whole world seemed to be gripped in a ferocious storm.

The huge whale continued to chase Wu Yu!

As though the whole of the Ancient Demon Realm was its territory.

Wu Yu did not hesitate, but continued to flee. Soon, the giant whale had left the Mountain in the Sea, and had not brought much seawater with it. Seemed like it was not that special. After all, a corpse puppet was a corpse puppet. It was indeed a killing machine, but without its creator supervising, it was not that smart.

As they left the Mountain in the Sea behind, Wu Yu was no longer that afraid of the giant whale now. He had also clashed with the giant whale a few times. Although Wu Yu had been beaten back, but he could find a way through!

Besides, he had helpers.

Although Full Moon of Nanshan and Ye Xixi were not as strong as he was, but they each had their own Mystiques which were formidable in their own right.

For example, Gone from the Skies and Black Sand Demonic Shadow.

At least, protecting themselves should not be a problem. Besides, the two had already taken their Nine Cycles of Imperial Immortal Body and Hell Incarnation Avatar to fairly advanced levels!

Swish swish!

As Wu Yu paused for a moment, Full Moon of Nanshan and Ye Xixi both flew out of the Floating Dreams Pagoda.

Wu Yu alone was not that confident. He would have to rely on their support. Although their three legacies came from similar sources, but they very seldom joined forces like this.

Wu Yu took up most of the giant whale's attention. At this time, he used Lawful Embodiment of Heaven and Earth to turn into a giant, and then the Immortal Ape Transformation, sprouting golden monkey fur. With the Thunder Flame Immortal Emperor's Celestial Pillar in hand, he was almost exactly like the Great Sage, Heaven's Equal.

This huge golden ape arrested most of the black whale's attention.

As for the wily Full Moon of Nanshan, he had already hidden himself with Gone from the Skies from the get go. However, he would definitely appear at the critical moment to harass the opponent and lend Wu Yu a hand.

"Finish him!"

The three joined hands.

Wu Yu rushed forth. He had not used Immortal Ape Transformation for a long time, and had forgotten the feral power it gave him.

The feeling came back to him now.

And in his hand was the great void immortal treasure, Thunder Flame Immortal Emperor's Celestial Pillar!

He roared in response, and the world again shook. At least in terms of aura, he was the giant whale's equal!

Rush!

The Thunder Flame Immortal Emperor's Celestial Pillar crackled with golden flame and lightning. The golden light flooded the area, illuminating everything for thousands of li. At the center of this expansive nimbus was the Thunder Flame Immortal Emperor's Celestial Pillar. Wu Yu appeared before the giant whale, bringing his staff down with a million jin of strength, crashing down on the giant whale's head!

Rumble!

But in the same instant, the giant whale opened its mouth, and black pearls began to pour out. They formed a mass as hard as metal, and came cascading towards Wu Yu!

Wu Yu sensed danger!

Even with the Thunder Flame Immortal Emperor's Celestial Pillar targeting his opponent, he would very easily be overwhelmed by this black mass!

But at this time, the benefits of having Ye Xixi and Full Moon of Nanshan support him showed itself. The terrain suddenly shifted, the mountains themselves rearranging into a solid black wall that sheltered Wu Yu. Not only was the giant whale smashed by Wu Yu's staff, it was also harangued by Ye Xixi's Mystique!

Although the black sand wall very quickly crumbled, but Wu Yu was already clear.

With three, they could keep up the offense.

Just as Wu Yu hid himself away, tendrils burst out of the soil around the black whale. They were alive, and tickled the clouds themselves, spurting forth in clusters of millions, a dense wriggling mass of knife-like tentacles that lashed and tangled the black whale.

Pa pa pa!

Huge trees beat the giant whale severely!

Smack!

The black whale gave a furious bellow, and shrugged violently, smashing all of the trees. Yet it did not run, but instead turned to face Wu Yu and the others. It opened its mouth again, and it was not the flood from before, but a vortex. It was trying to suck up and swallow Wu Yu and the others!

After all this time, it was the first time that Wu Yu was on the receiving end of the devouring.

Full Moon of Nanshan and Ye Xixi obviously could not deal with this. Even if he hid, he could not avoid this devouring. The two were in danger!

Wu Yu had to save them quickly!

Without hesitation, he used Submerged Cloud Seal!

In combination with the Violent Art, he reached a new peak of power!
