Full health is the kill threshold, no matter if you're a god or a demon!

As they passed through a narrow passage, a small hole in the rock wall on the left suddenly burst open, and a dark purple tentacle as thick as a bucket and covered with suckers shot out like lightning, heading straight for Sola!

"Watch out!" Liu Nian reacted extremely quickly, sweeping his spear horizontally.

clang--!

The tentacles collided with the spear, producing a metallic clang.

The tentacles were far tougher than expected. Liu Nian's attack only cracked a few holes in their surface, causing them to spurt out dark green liquid, but it failed to sever them.

Even more bizarrely, the injured tentacle quickly retracted into the hole, and almost at the same time, more than a dozen holes in different directions on the right side of the rock wall, above, and underfoot burst open, and more than a dozen identical tentacles swarmed out!

"So many?!" Sora exclaimed in shock, brandishing her trident and barely managing to block an attack from a tentacle.

"No matter how many, just cut them down." Liu Nian's eyes turned cold.

He held nothing back, unleashing his [Vast Mind]! Dark red energy enveloped his entire body, and the swing of his spear created terrifying vortexes.

-4521 million!

-4487 million!

-4503 million!

The spears thrust out like a storm, requiring no aiming at any weak points, no skill needed, it was all about numbers!

One by one, the tentacles were severed, ink gushing from the cuts, spreading into murky clumps in the clear water.

But new tentacles keep emerging from other holes.

In just one minute, Liu Nian had severed more than a dozen tentacles, but the number of tentacles attacking showed no signs of decreasing.

This scene is just like the one in "Deep Rising".

"These tentacles can definitely regenerate! We can't waste time here." Liu Nian frowned and ordered the Echo Crab, "Clear the way!"

The Echo Crab raised its massive pincers, aiming them at the passage ahead—

[Sonic Cannon]!

Om-! ! !

A visible ring-shaped sound wave burst from the jaws, instantly displacing the seawater in front and creating a brief vacuum channel.

The holes in the rock walls on both sides of the passage collapsed under the impact of the sound waves, and several tentacles that had just emerged were instantly turned into minced meat.

"Go!" Liu Nian grabbed Sola and rushed along the channel opened by the sound waves.

Three minutes later, they reached the deepest part of the nest—a huge spherical cave.

In the center of the cave, a group of indescribable creatures floated.

Its main body resembles a squid magnified a thousand times, with a dark purple body and its skin surface covered with constantly wriggling tumors and eyes.

However, its head was abnormally deformed, with three huge mouths covered with sharp teeth, and several thin, tongue-like appendages protruding from each mouth.

[Level 99 Boiling King BOSS (Legendary)]

In a small niche above the cave behind it, a curled-up silver figure can be vaguely seen—it is the mermaid princess Serana.

She seemed to be bound by some invisible force, unable to move, and could only anxiously look down.

Tentacles and the Little Mermaid...

"Tsk tsk," Liu Nian sighed, then gripped his spear tightly, ready to fight.

But the King of Boiling's reaction was unexpected.

Its three enormous mouths emitted sharp hisses simultaneously, then it suddenly turned and ran away.

The mollusk's body melted away and seeped into a huge hole at the bottom of the cave at an astonishing speed. Clearly, it had prepared an escape route long ago.

"Trying to escape? Behemoth!" Liu Nian urgently contacted the Behemoth guarding outside via telepathy. "The target escaped from the bottom of the lair. Intercept it! Capture it alive if possible!"

The floating city prison is still quite empty; it would be perfect to capture it and have it keep company with Gruba Flamebeard, the Abyss Dwarf Lord of Molten Hammer Keep.

Although both the Colossus and the Boiling Lord belong to the legendary level, there is another important aspect of combat power in water that is different from that on land: size!

To put it simply, underwater creatures also have to follow the rule of big fish eating small fish.

Although the Lord of Boiling is not small in size, it still poses no threat to the Colossus.

"Woo~" the Big Mac responded.

"Let's save them first," Liu Nian said, turning to the alcove.

Sora swam toward Serana, but just as he was about to touch the edge of the niche, he suddenly saw Serana shaking her head frantically, making warning gestures with her hands, and her lips moving rapidly—she was speaking, but the water was too soundproof for Liu Nian to hear.

But Sora, being an amphibian, heard it.

His expression changed drastically, and he turned around abruptly, shouting at Liu Nian, "Back off! There are still some here—"

He hadn't finished speaking.

The entire cave seemed to move slightly.

The once clear seawater suddenly became viscous and heavy, enveloping the two like glue.

The rock walls, the ground, the ceiling—all surfaces began to seep out a translucent, bluish substance. This substance spread rapidly, connected, and eventually covered the entire cave, turning it into a sealed space.

Liu Nian finally understood where that feeling of being spied on came from.

From the very beginning, they were inside the body of a larger organism!

And at that moment, the creature finally revealed its fangs.

Dozens of distorted faces made of water appeared on the surrounding "walls." The faces opened their mouths and emitted silent shrieks, while countless pale blue, translucent tentacles shot out from all directions, wrapping around the two.

Liu Nian immediately received an attack alert:

[Level 99 Demon King Jellyfish BOSS (Mythical)]

The moment the tentacles wrapped around his body, Liu Nian felt a strange suction force coming from him, and his health points began to decrease at a fixed rate of 1% per second. Although it was not much, it was continuous.

What's more troublesome is that the body is trapped.

It wasn't that he was completely immobilized, but rather that the surrounding seawater had turned into an extremely thick gel, holding him firmly in place, making every movement incredibly difficult! Even breathing felt much more suffocating!

"Echo Crab, sonic attack!" Liu Nian ordered.

The Echo Crab's giant pincers vibrated, unleashing a ring-shaped sonic wave.

But when the sound waves hit the surrounding dark blue "walls," they were like mud oxen sinking into the sea, not even causing a ripple—this glue had an extremely strong ability to absorb and disperse sound waves.

Liu Nian tried to swing the spear, but the resistance was absurdly high, and every inch of movement required tremendous effort. He finally managed to pierce one of the tentacles, but the spear tip seemed to pierce through flowing water, exiting directly from the other side, while the tentacles remained completely unharmed.

【immunity】

The attacks all displayed immunity!

"Physical attacks are ineffective," Liu Nian frowned. "Sora, try water magic!"

Sora gritted her teeth and chanted, the trident in her hand glowing blue—[High-Pressure Water Gun].

The thick jets of water crashed against the wall, only to be absorbed silently.

Sora and Liu Nian then tried various methods, and Liu Nian even used a deliberate punch, but all of them were ineffective attacks!

How is that possible?

This thing is only mythical, yet it's so difficult to deal with?

"It's useless!" Sora exclaimed. "This stuff is just water! It's completely immune to damage!"

water……

Liu Nian suddenly thought of something.
