While the undead Sanguine Vulture Spawn kept the Dust Naga occupied relentlessly, Thoren finally gained precious time to reorganize his undead army properly.

His mind moved rapidly while calculating every movement across the battlefield.

The terrifying Dust Naga Mini Floor Boss was far stronger than anything he had fought previously.

One mistake would cost him his life instantly.

Without hesitation, Thoren commanded the undead shield soldiers to march directly toward the Dust Naga while forming a defensive wall.

Behind the shield formation stood the undead Storm Tyrant, prepared to unleash devastating attacks whenever opportunities appeared.

To the left side of the battlefield, Thoren positioned the elite undead servants carefully in order to launch coordinated assaults.

Meanwhile, on the right side, the undead Royalty Stonewall advanced slowly with its gleaming black blade dragging heavily across the sanctum floor.

Sparks scattered continuously behind the blade while its hollow eye sockets burned fiercely with soul fire.

As for the undead Elite Jackal Beastman, Thoren ordered it to remain beside him as his personal protector.

"Now it is my turn," Thoren thought coldly while murderous rage burned intensely within his eyes.

Thud! Thud! Thud!

The heavy footsteps of the undead shield soldiers reverberated throughout the sanctum like drums of war echoing across a graveyard.

The Dust Naga immediately detected their approach through the vibrations spreading across the floor.

Hissss!

Instantly, the massive serpent opened its enormous maw before releasing a deadly compressed sand spear attack directly toward the advancing shield formation.

Whoosh!

The compressed sand spear tore violently through the air with horrifying force.

Boom!

The attack crashed directly into the shield formation. The entire sanctum trembled heavily while dust exploded upward throughout the battlefield.

Several undead shield soldiers were forced backward by several steps beneath the overwhelming impact.

Yet not a single one lost its footing completely.

The undead soldiers stabilized themselves almost instantly before continuing their advance once more.

Thoren's eyes narrowed sharply.

The Peak Bronze grade shields truly exceeded his expectations.

Bang! Bang! Bang!

At that exact moment, attacks from both sides of the battlefield arrived simultaneously.

The elite undead servants assaulted from the left while the undead Royalty Stonewall attacked from the right side mercilessly.

Hissss!

The Dust Naga cried out painfully while its massive body writhed violently throughout the sanctum.

Enraged, the monster unleashed a terrifying sandstorm around itself in order to sweep away the approaching undead forces.

Whoosh!

The raging sandstorm exploded outward violently like a miniature catastrophe.

The elite undead servants were blasted away instantly before crashing heavily into the sanctum walls.

Crack! Crack!

Spiderweb fractures spread rapidly across the ancient stone walls from the impact. 𝓯𝓻𝒆𝙚𝒘𝓮𝙗𝓷𝒐𝓿𝙚𝒍.𝙘𝓸𝙢

The undead servants collapsed onto the floor like shattered weapons discarded after battle.

Yet in the very next second, they rose back onto their feet mechanically before marching toward the Dust Naga once more.

Pain meant nothing to the undead.

Fear meant nothing.

Only their master's commands existed within their dead minds.

Ting! Ting! Ting!

The eerie echoes of the Choir Bell Charm spread continuously throughout the chamber.

However, compared to the earlier Dust Naga creatures, the effect upon the Mini Floor Boss was extremely limited.

The massive serpent froze momentarily before recovering almost immediately.

Seeing this, Thoren showed no surprise whatsoever.

The Choir Bell Charm remained only a Low Bronze grade item after all.

Against a terrifying Level Thirty Mini Floor Boss, its suppressive power naturally weakened greatly.

Still, Thoren possessed another advantage.

Without hesitation, he unleashed the full pressure of his awakened soul aura directly upon the Dust Naga.

Boom!

The invisible soul pressure crashed downward instantly.

The effect appeared immediate.

The Dust Naga's movements slowed noticeably while its reaction speed weakened slightly beneath the overwhelming soul pressure.

Bang! Bang! Bang!

Meanwhile, the barrage of attacks from the undead Sanguine Vulture Spawn continued relentlessly from above.

The blood colored creatures moved across the sanctum like crimson lightning while slashing repeatedly at the Dust Naga's exposed scales.

Fragments of shattered scales scattered throughout the battlefield continuously.

Dark blood splattered violently against the floor and walls.

Just then, the undead shield soldiers finally advanced close enough toward the Dust Naga.

Immediately, the undead Storm Tyrant exploded forward from behind the formation.

"Chain Combo!" Thoren commanded mentally.

Boom!

The undead Storm Tyrant's massive undead muscles bulged violently while dark energy surged throughout its gigantic body.

Its already towering height appeared even larger beneath the enhancement.

The air surrounding the undead creature distorted unnaturally beneath the overwhelming force gathering around its hammer.

Then it leaped directly into the air.

Its colossal hammer descended downward mercilessly toward the Dust Naga's head.

Boom!

The hammer strike landed directly upon the serpent's skull with horrifying force.

The Dust Naga's gigantic body tumbled violently backward across the sanctum floor.

Hissss!

A soul rending scream erupted from the creature's maw instantly.

Before the Dust Naga could recover from the devastating impact, attacks rained down from every direction simultaneously.

Clang!

Slash!

Boom!

Its hardened scales shattered apart continuously beneath the coordinated assault.

Then suddenly, the undead Royalty Stonewall stepped forward with terrifying speed.

Slash!

Its gleaming black blade sliced directly through the Dust Naga's damaged scales before carving deeply into its flesh.

Dark blood erupted outward violently like a broken dam.

Howllll!

Another agonized scream escaped from the Dust Naga immediately.

The battlefield descended further into bloody chaos.

Then something terrifying happened unexpectedly.

The Dust Naga's massive body suddenly began dissolving apart into flowing sand.

Within moments, the gigantic serpent transformed into an enormous living sand dune occupying the center of the sanctum.

Seeing this strange transformation, Thoren sneered coldly instead of panicking.

"Continue attacking!" he ordered immediately.

Bang! Bang! Bang!

The undead forces continued assaulting the living sand dune without hesitation.

The undead Storm Tyrant smashed downward repeatedly with its hammer while blades and spears pierced continuously into the shifting sand mass.

Less than three seconds later, a miserable hiss echoed painfully from within the sand dune.

Immediately afterward, the Dust Naga's body began reforming rapidly back into its original serpent shape.

The moment it fully reformed, the Dust Naga descended into complete madness.

Hissssss!

The gigantic serpent rampaged violently throughout the sanctum while moving erratically in every direction.

Bang! Bang! Bang!

One undead servant after another was struck directly by its massive body and tail.

Several undead servants were launched violently across the battlefield before smashing heavily into the sanctum walls.

The Dust Naga's gigantic tail swept across the battlefield brutally before crashing directly into the undead shield soldiers.

Boom!

All ten undead shield soldiers were blasted backward simultaneously before tumbling heavily across the floor.

Yet despite the devastating impact, the undead shield soldiers immediately rose back onto their feet once more.

Without hesitation, they resumed marching toward the Dust Naga with their heavy shields raised firmly ahead of them.

Above the battlefield, the undead Sanguine Vulture Spawn continued their relentless assault without pause.

Their speed remained terrifyingly fast.

Blood red streaks flashed repeatedly throughout the sanctum while their feather blades carved deep wounds into the Dust Naga's neck continuously.

By this point, nearly all the scales protecting the Dust Naga's neck had already shattered completely beneath their attacks.

Without the undead Sanguine Vulture Spawn constantly harassing the monster from above, the entire battle would have turned disastrous long ago.

Suddenly, the Dust Naga twisted its gigantic head toward Thoren once more.

Murderous killing intent exploded from its glowing eyes instantly.

Its maw opened widely while compressed sand energy gathered rapidly within its throat.

The creature clearly intended to eliminate Thoren personally.

However, before the sand spear attack could reach him, the undead shield soldiers intercepted the attack immediately.

Boom!

The shields trembled violently while sparks and dust exploded outward from the collision.

At the same moment, countless attacks descended upon the Dust Naga simultaneously.

Slash!

Hammer strikes.

Blade strikes.

Axe strikes.

Spear thrusts.

Every type of attack rained mercilessly upon the Dust Naga from every possible angle.

The sanctum transformed completely into a macabre battlefield overflowing with blood and destruction.

Dark blood splattered endlessly throughout the chamber.

Shattered flesh scattered everywhere like torn scraps of meat.

The Dust Naga's movements gradually slowed more and more beneath the relentless assault.

Its massive body now carried countless wounds.

Its scales had mostly shattered apart completely.

Its blood covered nearly the entire sanctum floor.

Seeing this, Thoren believed victory was finally approaching.

However, just as he thought the battle had nearly ended, a terrifying change suddenly occurred beneath his feet.

The ground softened instantly.

Then the floor collapsed violently inward.

A gigantic sinkhole opened directly beneath him and the sense of danger exploded throughout his mind immediately.
