My only profession!

"Continue."

No sooner had he spoken.

White Night's figure instantly appeared before the fifth palace.

This palace was completely different from the previous four; it couldn't even be called a palace.

There was no magnificent hall, no dazzling runes, only a grey light gate suspended in the starry sky.

Twisted lightning coiled around the light gate. This lightning was neither purple nor golden, but a deep grey-black, devouring even the light of stars wherever it touched.

There were no words on the lintel, only a crack running across the light gate. Visible grains of time flowed within the crack, as if the gate itself had been torn from a spatial-temporal rift.

"Is this the final challenge?"

White Night gazed at the light gate, a faint prickling sensation on his fingertips.

The blade of the Eternal Demon Blade was trembling slightly, and the golden afterimage on its side flickered erratically.

He took a deep breath and stepped into the light gate.

The surrounding scenery abruptly changed. There was no grand hall as expected, only a chaotic grey space.

There was no up, down, left, or right in this space, only endless grey-black lightning slowly flowing. Each bolt of lightning dragged a long temporal wake; some bolts had not yet hit their target, but 'past' afterimages already appeared on their trajectory, while others prematurely revealed 'future' explosion marks.

"I am the beginning of thunder, and also its end."

A voice without a source echoed in the space, like a whisper in his ear yet also resonating from the depths of his soul.

In the center of the chaotic space, a grey-black bolt of lightning slowly condensed. It had no specific form, sometimes transforming into a net woven from billions of lightning threads, sometimes coalescing into a singularity that devoured light, and sometimes taking the form of a phantom identical to White Night's figure!

Even the weapon it held was identical to the Eternal Demon Blade, except that it flowed with grey-black light all over!

"The Fifth Gate Guardian, primal thunder shadow!"

White Night gripped the hilt, sweat seeping into his palm.

This guardian had no physical body, no aura, yet it made him feel an unprecedented pressure.

The opponent seemed to be the personification of the Thunder Law itself, every move perfectly aligned with the operation of this space.

The next instant, the primal thunder shadow moved.

It didn't swing its blade, but merely raised its hand and pointed at White Night.

In a flash, three grey-black bolts of lightning shot from three different directions. Strangely, the trajectories of these lightning bolts were not straight, but twisted in a spiral, as if traversing different temporal-spatial layers!

Even more astonishingly, White Night's retina prematurely displayed an image of himself being struck by lightning three seconds later—his left shoulder pierced, his health plummeting by hundreds of millions instantly!

"Time Law?"

White Night's pupils constricted slightly. He pushed off the ground, his figure shifting three zhang sideways in the nick of time.

But the three bolts of lightning seemed to have eyes, their trajectories changing accordingly, still striking towards his new position.

With a fierce look in his eyes, White Night no longer dodged.

He flicked his wrist, and the Eternal Demon Blade abruptly drew an arc of dark gold. Within the blade's glow, fragments of the law awakened after devouring the Holy Edge Sword intertwined, precisely striking the intersection of the three lightning bolts!

"Chii—!"

Boom—!

The moment the blade's glow collided with the lightning, the heavens and earth shook violently, and a subtle space-time twisted wildly around them!

The three lightning bolts, as if encountering their nemesis, froze in mid-air. Their grey-black outer shells peeled off layer by layer, revealing the pure essence of thunder within, finally dissipating into specks of light.

But the primal thunder shadow's attack did not end.

Its figure flickered, splitting into nine identical phantoms. The grey-black demon blade in each phantom's hand glowed with different hues.

Some were entwined with temporal sand, some flowed with spatial folds, and others burned with pure annihilation flames.

The nine phantoms simultaneously swung their blades, and nine different blade glows intertwined in the air, forming a vast net that covered the entire space and descended upon White Night!

White Night took a deep breath, raising his power to its peak for the first time.

The dark purple and gold on the Eternal Demon Blade intertwined into a spiral pattern. The blade trembled slightly, as if echoing his surging battle intent!

He didn't choose to forcefully resist at first, but instead used an unusual footwork, weaving through the gaps in the net of blade glows.

Each movement was perfectly timed, avoiding the blade glows while continuously striking back with his demon blade.

Whoosh—!

Whoosh whoosh whoosh—!

These counter-attacks, though seemingly scattered, precisely struck the weak points of the nine phantoms.

When the first phantom was hit, its body instantly became transparent, as if time had been drained from it!

The second phantom disintegrated into countless spatial fragments the moment the blade glow touched it!

The annihilation flames on the third phantom were extinguished by the blade glow!

"Interesting."

The primal thunder shadow's true body let out an ambiguous exclamation of praise.

The next instant, the nine phantoms suddenly merged into one, their figure soaring to a thousand zhang tall. The grey-black demon blade in its hand also grew, and countless trajectories of stars being born and dying appeared on its blade!

It slowly raised its demon blade, and the entire chaotic space suddenly became still.

The flowing lightning solidified in mid-air, the dancing light particles hovered in place, and even White Night's breathing seemed to be stretched countless times!

"Thunder: Final Judgment."

Boom—!

The thousand-zhang demon blade struck down with the might to crush all laws!

Wherever the blade's glow passed, space exhibited patterns like shattering glass, and time began to flow backward.

Countless afterimages of civilizations destroyed by lightning flashed within the blade's glow, intending to erase White Night along with his very existence!

White Night's expression was as grim as iron. The power of this strike far surpassed all attacks he had encountered before, even subtly touching the realm of 'rules'.

He no longer held back, gripping the Eternal Demon Blade with both hands, pouring all his power and understanding of laws into it.

"Om—!"

The Eternal Demon Blade let out a dragon's roar that echoed through the chaos. The dark purple and golden patterns on the blade's surface completely lit up, intertwining into a spinning Taiji symbol.

In the center of the symbol, a point of chaotic light slowly lit up. That was the new origin born from the fusion of two completely different law powers after devouring the Holy Edge Sword.

"Break."

White Night let out a low shout, swinging his blade upwards with both hands.

The dark golden blade glow and the grey-black blade glow collided in the center of the space. There was no energy explosion, only two completely different laws fiercely confronting each other.

Time and space continuously twisted, shattered, and regenerated at the collision point, and countless thunder origins emitted painful shrieks under the tearing of the laws.

White Night's arm trembled slightly, his tiger's mouth numb from the shock. This was the first time he had felt such a strong recoil since starting the challenge.

But the battle intent in his eyes grew even fiercer. He suddenly applied more force to his wrist, and a devouring suction burst forth from the dark golden blade glow, slowly beginning to swallow the primal thunder shadow's grey-black blade glow.

The primal thunder shadow's thousand-zhang tall body wavered for the first time, and the stellar trajectories on its blade began to become chaotic.

It seemed somewhat surprised, yet also somewhat understanding.

The grey-black blade glow suddenly disintegrated, transforming into countless tiny bolts of lightning that surged towards White Night like a tide.

These tiny lightning bolts no longer attacked, but instead spun rapidly around him, as if probing his essence.

White Night did not stop them, merely gripping his demon blade, vigilantly watching the primal thunder shadow's true body.

In the chaotic space, one person and one shadow confronted each other... a few breaths later.

The tiny lightning bolts still spun around White Night, as if scrutinizing the challenger's qualifications.

The grey-black on the primal thunder shadow's thousand-zhang body gradually faded, revealing the purple-gold dual-colored lightning flowing within, faintly resonating with the Eternal Demon Blade in White Night's hand.

"The clash of laws, the contest of essence... you have surpassed the boundary of 'Source'."

The primal thunder shadow's voice became clear, carrying a hint of human-like relief. "But the Way of Thunder ultimately requires one to personally sever the past."

Before its voice faded, it suddenly disintegrated into billions of purple-gold lightning bolts. These lightning bolts did not attack; instead, they transformed into a surging river, rushing towards White Night.

Countless fragments of Thunder Law floated in the long river: nascent thunderclaps, destructive thunderous storms, temporal thunder patterns, spatial thunder marks. Each fragment contained ultimate power and insight.

White Night's eyes sharpened. This was the final test: to accept the River of Thunder, either to merge with it or be torn apart by it.

He did not hesitate, opening his hands and holding the Eternal Demon Blade horizontally in front of him, allowing the purple-gold River of Thunder to wash over him.

Excruciating pain instantly swept through his entire body, as if countless small knives were cutting his soul and flesh. But he gritted his teeth, operating all his power to guide the River of Thunder into his body.

The Eternal Demon Blade now burst forth with dazzling light, its blade transforming into a massive vortex that swallowed and refined those violent Thunder Law fragments one by one, then fed them back to White Night.

After an unknown period, when the last purple-gold lightning bolt integrated into his body, White Night's aura surged dramatically. Dark purple and golden lightning intertwined around him, and as his eyes opened and closed, tiny lightning arcs even danced in his pupils.

He slowly gripped the Eternal Demon Blade, feeling as if he had established some mysterious connection with this chaotic space, and with all thunder between heaven and earth.

"So that's how it is." White Night murmured softly, then swung his blade at the void.

There was no world-shattering phenomenon. The primal thunder shadow's final essence calmly dissipated in the blade's glow, transforming into a purple-gold dual-colored rune that slowly merged into White Night's glabella.

This notification was not confined to the trial space; instead, it suddenly appeared in golden characters before the eyes of all professionals in all civilizations across the entire universe!

Holy Light Civilization, Sacred Hall.

Lu Jing, who had been meditating with his eyes closed, suddenly opened them, his golden pupils filled with shock: "Uniqueness? Thunder Sovereign? This is impossible! No one has ever passed the fifth stage of the Eternal Divine Tower!"

The elders around him also rose, their faces filled with disbelief: "Lord Lu Jing, who exactly is this White Night? To break the Divine Tower's ten-thousand-year record!"

"…"

...Holy Pearl Civilization, a floating island.

Fu Zhen, the strongest professional of this era, looked at the golden notification, and the teacup in his hand shattered with a 'crack': "There really is a Unique Grade above the Source Grade... Blue Star Civilization? A civilization I've never heard of, yet it can produce such a monster!"

...Watchtower Civilization, a steel fortress.

Qin Ye slammed his fist onto the alloy table, which instantly dented: "Thunder Sovereign... controlling all Thunder Laws? Such a privilege is infinitely close to the realm of 'True Gods'!"

"Investigate immediately! Find out all information about the Blue Star Civilization!"

...Blazing Illusion Civilization, Volcano Temple.

Lin Leer stared at the words "White Night" on the notification, her eyes complex: "Thunder Sovereign... a Unique Hidden Class. This growth rate is simply terrifying!"

Xiao Yan, who had just been revived by special means, saw the notification, and his face instantly turned ashen: "Even Lord Xiao Jin couldn't pass the fifth stage of the Eternal Divine Tower... how could a professional from a new civilization possibly do it...?"

Top professionals from other civilizations also exploded in discussion.

Some civilization magnates smashed their cherished treasures on the spot, some urgently convened high-level meetings, and others dispatched their most elite intelligence units to try and gather information on the Blue Star Civilization... For the first time, the eyes of the entire universe were so focused on an obscure civilization!

At the center of it all, White Night stood in the chaotic space, feeling the surging thunder power within him, a faint smile gracing his lips.

Fourth Class Advancement, complete!
