-1530- The excessive spar

At the edge of the underground city, magic and jutsuryoku clashed violently, creating quite a commotion.

The residents immediately sensed this disturbance, and panic spread among them.

"Isn't that where those monsters live?"

"Have they finally gone berserk?"

"Damn it, I knew we couldn't trust those humanoid armored beetles!"

"Now they're showing their true colors!"

"Quick, report this to Her Holiness the Pope!"

"Hurry!"

The residents gathered in groups, hastily jumping to conclusions. They all ran toward the direction of the Aries Palace, clearly revealing their long-held animosity toward outsiders.

Emerging from the Aries Palace, River and Cris also noticed the scene and their expressions quickly changed.

"Who's fighting over there?" River was puzzled.

"Who else could it be?" Cris responded with a wry smile.

In this underground city, only two people could emit such potent magic and jutsuryoku in a contest of strength.

"Could it be Rozen and Miss Emilie?"

River quickly realized, his face turning pale.

A fight between a human and beetles in this place would be the worst possible scenario for the already anxious residents.

It wasn't surprising that as soon as the disturbance arose from the direction of the armored beetles' residence, the residents immediately assumed it was a malicious attack. This was no trivial matter.

Even without factoring in the sensitive attitudes of the residents, just considering the power of those two individuals—if they really got serious, the entire underground city could be destroyed.

Thinking about this, River could no longer stay put.

"No, we have to stop them immediately!"

Without hesitation, River activated his flying magic and rushed toward the scene.

"I'll go with you!" Cris hesitated for a moment before also activating her flying magic and following him.

...

Meanwhile, on the battlefield, Rozen had already drawn another talisman after watching the earth spikes he had summoned with his Earth Talisman get blasted apart by Emilie's jutsuryoku projectiles.

"Earth generates metal!"

Rozen threw a Metal Talisman, which merged into the shattered earth spikes.

In an instant, swords of metal materialized from the broken spikes and shot toward Emilie.

"Clang! Clang! Clang! Clang!"

Emilie swiftly retreated while slashing with her jutsu sword, deflecting the incoming metal swords.

However, Rozen was already activating his Water Talisman.

"Metal generates water!"

The Water Talisman slipped between the deflected swords, and with a flash of spiritual energy, bubbles of water formed along the blades.

"Splash!"

In moments, the metal swords were engulfed by the bubbles, forming a torrential flood that surged toward Emilie.

"What kind of technique is this!?"

Emilie was stunned, but she dared not allow the surging flood to catch her. She quickly ascended into the air to evade the waves.

But by then, Rozen had already activated another talisman.

"Water generates wood!"

The Wood Talisman glowed within the flood, absorbing all the water energy and transforming into a towering tree. As it grew, its branches extended, entwining toward Emilie.

Like a firefly dodging through a dense forest, Emilie swiftly weaved through the branches.

However, the branches multiplied and thickened, eventually ensnaring Emilie completely, binding her tightly.

Seeing this, Rozen pulled out his final talisman, a Fire Talisman.

"Wood generates fire! The five elements resonate! By this command, Order!"

He threw the Fire Talisman onto the giant tree, which immediately burst into flames.

The blazing fire quickly spread across the towering tree, reaching the branches that had trapped Emilie.

Engulfed by the flames, Emilie disappeared within the raging inferno.

Thus, the roaring fire rose high, visible to all the residents of the underground city, who stood frozen in shock.

The air was rapidly consumed by the blaze.

The temperature surged, making everyone break into a sweat as the firestorm raged on like lava from a volcano, or a fiery tsunami wreaking havoc.

For a sparring match, this had escalated far beyond reasonable limits.

Though it was only the power of the Five Elements Talismans, when the five elements resonated with one another, their power naturally amplified significantly.

If Rozen hadn't diluted a wisp of his high-grade mana into ordinary mana, then converted it into spiritual energy and finally into jutsuryoku, even an ordinary Five Elements Talisman, when combined with the highly compressed jutsuryoku, could have destroyed the entire underground city.

Even with the dilution, the remaining mana was still immense.

With a large amount of mana transformed into spiritual energy and jutsuryoku to power the talismans, the resulting power was still considerable.

Rozen stood before the raging flames, watching the sea of fire before him without a change in expression.

"Could it be that you're done, big sis?"

Rozen simply taunted.

And then...

"Boom!"

From within the sea of flames, a black wave surged forth.

It was a wave of raw power.

And there was no need to guess what that black power was.

——Collapse Force.

A power that could disintegrate all matter and principles surged through the sea of flames, scattering the fire as it advanced.

Emilie's figure emerged from the flames.

"To think that you could push me to use Collapse Force so easily. This is the first time that's ever happened," Emilie's voice was filled with reluctance, yet the overwhelming power emanating from her caused the air to tremble.

Rozen's eyes gleamed.

For the Collapse Force that had formed in front of him was far stronger than the Collapse Force he had previously seen Real Nua wield.

Not only did it surpass Real's in quantity, but its quality was far superior.

This was the true Collapse Force.

Emilie combined her magic and jutsuryoku, forming a black wave of Collapse Force. As the wave surged through the sea of flames, the fire was completely extinguished.

The next moment...

"Shing!"

Emilie shot forward like an arrow, closing the distance to Rozen in an instant.

Her eyes gleamed with a killing intent sharper than any blade.

"Clang!"

The dark jutsu sword sliced through the air, striking Rozen's raised arm with immense force, generating a powerful gust that blasted outward.

The immense Collapse Force surged through the jutsu sword.

"Jutsu Sword Battle Skill—'Explosive Flash Sword!'"

With Emilie's shout, the Collapse Force detonated.

"Boom!"

A massive explosion erupted, shaking the entire underground city.
