Chapter 30: Undersea Adventure

These extraordinary sailors were at least second-order, moving quite swiftly through the water.

Moreover, there were several third-order experts and the fourth-order Buster.

These ordinary first-order undead were far too slow in the ocean compared to them.

When the two sides clashed in melee,

it was clear that the second-order sailors held a distinct advantage.

Furthermore, among the sailors, some possessed martial skills that could inflict considerable damage on these undead.

As he watched the melee, Gune's gaze swept across the surrounding ocean depths.

In the deep seawater before his eyes, aside from this batch of deep-sea undead, there were no other undead creatures.

While pondering, Gune casually opened the system.

Checking the Adventure System when idle was one of Gune's daily routines.

He hadn't noticed before, but now he saw it, and his heart stirred slightly.

Then a faint smile curled at the corner of Gune's mouth.

An adventure! It had appeared.

At that moment, on the adventure page,

a very concise adventure event had emerged.

[Adventure: Altar Chains]

[Adventure Content: Deep beneath the sea, an ancient seal has shattered. Reaching that location can grant the 'Altar Chains.' Note: The chains are surrounded by a large number of undead creatures.]

"Shattered altar? Altar chains?"

Gune closed the system and looked downward.

But his Source Vision could only see about three to four hundred meters; beyond that, it was pitch black and unclear.

Nor did Gune see any undead creatures.

Then Gune re-entered a state of "observation," opened his system, and began to deliberate.

"First, the sealed altar has already shattered, so it should pose no threat. Second, the target this time is the altar chains. And..."

As he pondered, Gune clicked on the system page for details.

"The system also provides a long, complex incantation. Hmm... this incantation has a sense of deep time and age. The practice of adding meaningless 'lingering syllables' after the spells seems to have existed only in ancient history two thousand years ago!"

"This altar has some history."

"Overall, the altar itself and the chains pose no danger."

"The only danger is these marked undead!"

"'The chains are surrounded by a large number of undead creatures'?" Gune chewed over the meaning of these words.

"The system's words often need careful consideration. The number of undead is probably... really substantial."

"Of course, the exact number needs to be scouted carefully below."

"But before that, I need to have the Demon Ship leave this sea area. In case the undead swarm, I don't want them to tear the Demon Ship apart."

As he watched the battle, Gune was already planning his next moves in his mind.

This group of first-order undead creatures, under the attacks of the sailors who had corresponding lethality and were extremely fast, were all eliminated within two minutes.

Undead creatures are roughly divided into three types.

Soul-type, physical-type, and the current semi-soul type.

Physical-type include skeletons, zombies, and walking corpses, which are relatively easy to deal with.

Soul-type undead lack physical bodies, and even ordinary superhumans cannot see them. Without special means, these undead are extremely difficult to handle.

The ones before them, radiating dense black ghostly mist, were semi-soul type.

They possess some traits of physical undead and some traits of soul-type undead. Although hard to deal with, ordinary attack methods still have some effect on them.

If one has corresponding means, they become much easier to handle.

"Old Sea Chart, have Buster come to the helm. I need to discuss something with you all."

Seeing Buster return after killing the batch of first-order ocean undead, Gune said to Old Sea Chart beside him.

Old Sea Chart looked over and nodded slightly: "I'll notify him to come."

Soon, the four gathered at the bow of the Demon Ship, which was slowly advancing at a depth of about three hundred meters.

"I sense a large concentration of undead below."

Gune did not beat around the bush and spoke directly.

"Hmm?"

The others were startled at his words.

"Undead creatures love to gather in groups. When they congregate, the undead mist spreads, making each undead comfortable. It's not surprising if there's a large number below."

Old Sea Chart nodded slightly.

Gune continued.

"The undead above are all weak first-order ones, but the ones below are different—there might even be fifth- or sixth-order ones."

"You don't have effective means to deal with these undead, but I can handle them easily."

"So, you all steer the Demon Ship forward and dive. I'll go below to check the situation later."

The others nodded in agreement.

They might be able to fight mid-tier undead, but it wouldn't be easy to win.

And against high-tier undead, they would struggle greatly.

First-order undead move through water like dog paddling; second-order are slightly faster, but not by much.

Third- and fourth-order mid-tier undead are not like that.

Mid-tier undead can harness source energy to swim swiftly through seawater, much faster than the Demon Ship. Although they can't catch up to these extraordinary sailors, they can easily catch the Demon Ship.

High-tier undead possess considerable intelligence and move through water at speeds no slower than third- or fourth-order extraordinary sailors.

If entangled by high-tier undead, escape would be difficult.

Thus, facing potentially high-tier undead, they were reluctant to get involved if possible.

After giving his instructions,

Gune, alone and silent, descended slowly from beneath the Demon Ship toward the deep seabed.

As for the issue of losing sight of the Demon Ship if it sailed too far, Gune was not worried at all.

Having essentially completed the touch-molding and incubation of the Demon Ship, Gune could still sense its general direction even from a dozen nautical miles away.

When the Demon Ship left his field of vision, Gune began to accelerate his descent.

As he sank rapidly, Gune clearly felt the Secret Dragon Gills quickly adjusting the pressure between his body and the outside, allowing him to easily adapt to the deep-sea environment.

"Normally, these Secret Dragon Gills allow ordinary second- or third-order superhumans to reach depths of five thousand meters."

"But that's for ordinary extraordinary sailors. For me, my current physical defense rivals the toughness of black iron steel armor, and my body's resilience is extremely strong."

"With these Secret Dragon Gills, descending ten thousand meters should be no problem."

"And even in this deep-sea environment, I can still fight smoothly."

As he descended, nearing a depth of one thousand meters,

below him, 'deep-sea undead' floating in the seawater came into Gune's view.

There were over a dozen of them, all first-order undead.

Similar to the previous undead, these were also in a dormant state.

Gune immediately followed the Dark Principle and silently entered a state of absolute convergence.

His source energy, physical aura, and even soul aura were all wrapped by the Dark Principle.

In this state aligned with the Dark Principle, even if these deep-sea undead inadvertently saw Gune, they would not sense his soul or flesh aura; they would only think they saw a sinking piece of wood or stone.

As he continued descending,

soon, Gune saw a vast number of ocean undead floating in the deep sea.

Among these floating undead, second-order ones began to appear.

At that moment, a thought surfaced in Gune's mind.

"Does that strange altar chain really have such a strong attraction for these undead?"

"Or is the altar chain some kind of peculiar and powerful treasure?"

"But since the system recognizes it as an adventure, it can't be too bad."

When Gune reached a depth of two thousand meters, looking around, within three to four hundred meters centered on him, every ten to twenty meters, an undead floated silently in slumber.

This stretch of deep sea had become a veritable ocean of undead!
