In the end, everyone decided that a few elders would lead the way, while the other young disciples followed behind.

This arrangement was primarily because the elders were knowledgeable and powerful and could minimize danger.

Soon, everyone passed through the opened Crystal Gate and walked inside.

Upon entering, they were once again amazed, as it resembled a true Immortal Palace, with every object glowing brilliantly, like a real Dragon Palace.

The group walked through a long corridor, with walls engraved with powerful Sea Beasts.

Though merely stone carvings, everyone could still feel a Primordial Aura emanating from them.

Cautiously, they reached the end of the long corridor and then stopped.

Because ahead lay a genuine complex of buildings.

Various pavilions, towers, and squares were arranged intricately, like a real city, except it was an undersea city.

However, the only strange thing was, despite it being like an ordinary city, there were no signs of life.

It felt as if it were a dead city!

The group arrived at the true undersea city, gazing at everything around, deeply shocked.

At this moment, Dugu Aotian spoke in a deep voice, "Elder Song, I seem to sense a faint Spiritual Power fluctuation."

Upon hearing this, the elders also furrowed their brows, for Dugu Aotian was arguably the strongest among the younger generation, and if he mentioned a fluctuation, it couldn't be wrong.

Soon, under Dugu Aotian's prompt, everyone quickly sensed it as well.

Elder Song nodded slightly, "Indeed, there is a Spiritual Power fluctuation."

Lin Xuan also sensed a moment and then slightly raised his brows, because he not only sensed the Spiritual Power fluctuation but also felt another kind of fluctuation.

This wasn't to blame others for not feeling it, as among them, Lin Xuan likely possessed the strongest Soul Power.

Even the Dark Red Divine Dragon appeared puzzled, evidently having sensed something unusual too.

"Boy, be careful; I feel something odd here."

Upon hearing this, Lin Xuan nodded slightly and became secretly vigilant.

Afterward, the group set out again, aiming for the source of the Spiritual Power fluctuation ahead.

Based on their conjecture, these fluctuations likely originated from a Treasure.

Soon, Lin Xuan and the others moved out again, with the elder opening the way and the young disciples following behind, but compared to the previous corridor, everyone's speed increased noticeably.

However, just as they passed through a pavilion, countless blue bubbles suddenly emerged around them, with the surrounding sea water boiling like it was boiling, violently trembling.

"Not good, retreat quickly."

From the front, Elder Song suddenly shouted urgently.

With that voice, countless black shadows darted from all directions like black lightning, quickly striking at the group.

Fortunately, Lin Xuan and the others weren't ordinary people, and they reacted swiftly, retreating to the rear.

Clang! Clang! Clang!

Metallic sounds came from the front as those black shadows pierced into the ground, producing a metal-like sound.

Then, the group discovered that those lightning-like shadows were actually Long Spears.

Each spear was over a yard long, entirely You Lan, intricately engraved, with a swift stream of light dancing over it, clearly exuding a fierce aura.

Seeing these blue Long Spears, everyone's expression turned gloomy, as their aura suggested that these spears could indeed pose a threat to them.

Lin Xuan's brows furrowed because, during his earlier sensing, he felt a similar aura; it seemed that this vague energy fluctuation was the unknown threat before them.

Sure enough, the next moment, countless figures charged from all sides.

They wielded bright blue Long Spears, their aura fierce; it didn't take much to deduce the earlier ambush was their doing.

However, upon seeing these figures, everyone was stunned; they weren't human.

They had human bodies but shrimp heads, with scales covering their arms, appearing extremely bizarre.

"Damn, could these be Shrimp Soldiers?"

A few disciples' eyes widened, their tongues almost bitten off.

Elder Song quickly cautioned, "Be careful; these creatures are strong."

Even before his warning finished, the Shrimp Soldiers launched a fierce attack.

Each of them emitted blue Demon Energy, wielding cold Long Spears, rapidly advancing.

These Shrimp Soldiers were likely from the Demon Clan, living in the sea for years, exceptionally familiar with the environment, exceedingly agile.

The academy disciples were different, after all. They were fighting underwater, where even the sea water wasn't ordinary, imbued with a terrifying Primordial Aura.

In this way, their combat effectiveness was weaker than on land.

Thus, upon engagement, some disciples were sent flying.

Fortunately, there were many elders in the group, who decisively displayed powerful combat strength, holding their ground against the Shrimp Soldiers.

Yet, old hands were limited, and soon a disciple failed to dodge in time, pierced through by a blue Long Spear, pinned to the ground.

Blood surged, dyeing the sea red.

The battle was fierce, but fleeting; after swiftly dispatching a few disciples, those Shrimp Soldiers quickly retreated, hiding within the distant architecture.

Witnessing this scene, everyone's expressions turned grim.

They had just entered the Crystal Palace and were already ambushed, with even lives lost; it was indeed not a favorable omen.

"Everyone, be cautious; this place is more dangerous than expected."

Elder Song sighed; he had entered the Sky Secret Realm twice, thus understanding life and death deeply.

One should know, the Sky Secret Realm was not a benevolent place; death was frequent there, the deaths in this battle were considered highly fortunate.

However, clearly, this was merely the first wave of attacks; who knew if those hidden Shrimp Soldiers would strike again?

Lin Xuan's expression was also solemn; although the battle was brief, he killed several Shrimp Soldiers, yet couldn't turn the tide.

Fortunately, they had a significant number on their side, if truly desperate, they could surely defeat the opponent.

Then, under Elder Song's leadership, the group set out again.

But soon, they encountered Shrimp Soldiers once more.

This time, the number of Shrimp Soldiers exceeded before, matching approximately the number of Immortal Martial Academy disciples.

Moreover, astonishingly, not only were they armed with blue cold Long Spears, some even wore sea blue armor.

Like a formidable army, exuding a sharp killing aura.

A group of Shrimp Soldiers surrounded Lin Xuan and the others, blue Long Spears in hand, pointing directly at them.
