63: Magic Pattern Array

Underground Mo City, Central Dome Plaza.

The dome, dozens of meters high, was covered by a living network woven by Green Vine Demons, with countless underground fluorite stones dotting it like stars, casting a cold and constant faint light.

The plaza ground was made of dark black rock, flattened by Ironclad Earthworms and solidified by Worker Bee mucus. It was as smooth as a mirror, reflecting the sparse “starlight” above, making it appear even more vast and solemn.

On the tiered stone platforms surrounding the plaza, newly relocated Rank units performed their duties: Worker Bees transported supplies, while the Vajra Battalion drilled in the distant training grounds, their low shouts and the clang of metal faintly audible.

Within the purification zone, the World-Cleansing Lotus’s sub-plants emitted a soft white-gold aura, slightly dispelling the underground chill and oppression.

However, at this moment, all Rank beings, regardless of their Rank, instinctively stopped their movements, casting gazes of awe towards the plaza’s center.

Moyuan floated three feet above the ground in the Void Realm.

His aura was condensed, and his newly formed Thunder God Arm hung naturally.

The entire arm displayed a dark, deep purple color, as if it had endured ten thousand years of thunder. Yet, beneath the skin, faint gray Chaos light and dark gold thunder patterns subtly flowed, and the tips of his five fingers held an invisible sharpness that seemed capable of easily tearing space.

Just the subtle aura naturally emanating from him caused the air around the plaza to subtly distort, with tiny, subservient dark purplish-gold electric arcs flickering.

Before him, three items floated.

To the left was a violently churning mass of dark purplish-gold thunder plasma, constantly emitting low rumbles of thunder, as if a liquid sun roared within! This was the Origin thunder essence extracted from the torn thunder crystal core and initially refined by the Thunder God Arm. Its contained energy was enough to instantly vaporize a small hill!

To the right was a wisp of dark gray Chaos Qi current, as viscous as ink, constantly shifting form, and exuding an aura that seemed to devour all things! Originating from the crack in the magic bottle, it was the Chaos power that constituted the world’s Origin. Though thin, it possessed the strange characteristics of harmonizing, eroding, and reshaping everything.

In the center was a single World-Cleansing Lotus seed, only the size of a fist, entirely warm and smooth, displaying a pure ivory-white color, with intricate golden Sanskrit script naturally formed on its surface.

It emitted a faint aura of tranquility, appearing out of place yet crucially important amidst the surrounding violence and Chaos.

“Formation… Nine Heavens Thunder Hell…” Moyuan’s deep voice echoed through the vast plaza, each syllable causing a slight resonance in the surrounding Thunder Spiritual Power.

He slowly raised his deep purple Thunder God Arm.

There was no preparation, no incantation.

He suddenly spread his five fingers and, from a distance, clawed at the violent dark purplish-gold thunder plasma to his left!

“Ohm—!!!”

The thunder plasma, as if receiving an absolute command, let out a joyful yet painful roar, transforming into an extremely condensed purplish-gold torrent that fiercely poured into the Thunder God Arm!

Zzzzzzzzz—!!!

Terrifying energy instantly filled the entire arm!

The dark gold thunder patterns and Chaos gray light beneath the arm’s skin surged wildly at an unprecedented speed!

The arm’s muscles bulged, its bones emitted tiny groans of protest, and the deep purple skin instantly became transparent, as if one could see the thunder energy boiling within like a furnace!

Intense pain struck, yet it only made the Chaos gray light in Moyuan’s eyes intensify!

He then extended his right hand, forming a sword-finger, and with the deep purple, destructive arc-leaping fingertip, he fiercely pointed at the dark black rock wall at the edge of the plaza, which was ten meters high, smooth as a mirror, and reinforced with Spirit Stones!

“Engrave!”

The moment his fingertip touched the rock wall!

Boom—!!!

A condensed dark purplish-gold thunder light, its edges flickering with intricate Chaos gray light, erupted from his fingertip like a high-power plasma cutter, fiercely piercing into the rock wall, which was harder than steel!

Chirp, chirp, chirp—!!!

An ear-splitting sound of high-frequency cutting and energy scorching instantly exploded!

Rock powder mixed with molten crystallized material sprayed in all directions like fireworks!

The rock wall was easily etched away, but what remained was not a simple groove, but rather deep, foot-long, smooth-edged, flowing liquid-metal-like dark purplish-gold rune traces!

These runes were not Formation patterns from any known school in the world!

They were twisted, ferocious, filled with the most primitive thunderous tyranny and desire for destruction, yet at their core, they contained a hint of Chaos disorder and harmony!

Each stroke caused the Thunder Spiritual Power in the surrounding space to converge wildly, emitting a low rumble of thunder!

Moyuan’s arm was as steady as a machine, his fingertip moving rapidly across the rock wall, leaving behind lines of profound, complex, and interconnected thunder runes.

The Thunder God Arm acted as an inexhaustible energy source, efficiently converting the absorbed thunder plasma into a destructive beam for engraving the Formation.

But at the same time, the violent thunder energy was fiercely backlashing against his arm and mind!

Just then!

“Melt!” Moyuan roared.

The wisp of dark gray Chaos Qi current to his right, which had been stirring restlessly, instantly injected into his Thunder God Arm like a shark smelling blood!

A miracle occurred!

The moment the Chaos Qi current integrated, the violently conflicting thunder energy within the Thunder God Arm, which had been on the verge of exploding, was instantly imbued with a strange “resilience” and “adaptability,” becoming slightly “tamed”!

Though still incomparably domineering, it no longer clashed chaotically but flowed more smoothly and precisely according to Moyuan’s will, pouring into his fingertip!

The flickering Chaos gray light at the edges of the engraved thunder patterns became even more pronounced.

These gray lights acted like the most precise buffer layers and energy conduits, ensuring the thunder patterns’ ultimate destructive power while also granting them unimaginable stability and room for variation, allowing them to perfectly integrate with the Spirit Stones embedded in the rock wall, and even… devour the Spirit Stones’ power to nourish themselves!

However, pure destruction and Chaos could not form a lasting protective Grand Formation; it would eventually lead to self-destruction.

“Suppress!” Moyuan’s final gaze fell upon the World-Cleansing Lotus seed!

The lotus seed transformed into a soft ivory-white glow, merging into the Thunder God Arm.

A warm, sacred, Soul-calming power flowed through his arm, greatly alleviating the tearing pain and mental shock brought by the thunder and Chaos, making Moyuan’s will clearer and more focused.

More importantly, this power, as he engraved with his fingertip, subtly seeped, thread by thread, into the deepest core of those newly born, violent thunder patterns!

At the very core of those originally purely ferocious, destructive dark purplish-gold thunder patterns, a subtle, almost imperceptible, warm ivory-white luster quietly appeared!

It was like implanting a Soul-stabilizing divine needle deep within the heart of a raging Thunder Dragon!

This caused the entire rune, in addition to its ultimate destructiveness, to develop a strange “constant” and “purifying” characteristic, sufficient to resist the erosion of long years and external evil forces, maintaining the Grand Formation’s Foundation from decay!

With thunder plasma as ink!

With Chaos as catalyst!

With the lotus heart as suppressor!

With the Thunder God Arm as brush!

Moyuan’s figure flashed rapidly before the enormous plaza rock wall, his deep purple fingertip trailing dazzling dark purplish-gold and gray streams of light!

Wherever he passed, complex, ferocious, ancient, and powerful thunderous demonic runes spread, grew, and intertwined at an astonishing speed, gradually covering the entire massive rock wall, and then extending towards the adjacent rock walls, the dome, and even the ground!

Rumbling sounds! Cutting sounds! Thunderous roars! These formed the only symphony of this underground world!

Innumerable profound runes interconnected, forming an incredibly vast, complex, precise, and formidable three-dimensional network!

This network not only existed on the surface but, under the action of the Thunder God Arm and Chaos power, was deeply imprinted into the depths of the rock, merging with the earth veins, the embedded Spirit Stones, and even the entire structure of Underground Mo City!

This process lasted for a full day!

When the last finishing touch, a massive main rune resembling a vertical thunderous eye, was completed, Moyuan’s figure suddenly froze, suspended in the center of the plaza, his deep purple Thunder God Arm slowly lowering, the electric arcs flickering at his fingertips gradually fading.

The entire Underground Mo City fell into absolute silence.

All Rank beings held their breath, feeling an invisible, suffocating pressure slowly awakening.

Moyuan took a deep breath, his deep purple Thunder God Arm rising again, his five fingers spread, slowly pressing towards the most complex, converging all rune Veins—the core of the Formation eye—in the center of the plaza beneath his feet!

“Nine Heavens Thunder Hell… Activate!”

As his cold voice fell.

In his palm, dark purplish-gold and gray light burst forth!

Rumble rumble rumble—!!!!

The entire Underground Mo City violently shook!

The next moment!

All the thunderous demonic runes covering all directions were instantly lit up!

An incomparable, blinding dark purplish-gold and gray thunder light soared into the sky, instantly filling the Central Dome Plaza, and then, along countless passages, along the rock walls, along the ground and the dome, it spread wildly to every corner of the entire Underground Mo City!

Countless thick, dark purplish-gold lightning bolts, flickering with Chaos gray light, like awakened Thunder Dragons, surged and roared wildly between countless rune traces!

Forming an enormous, completely sealed thunderous cage!

Within the cage, destructive thunder energy churned and surged like a tangible tsunami!

The air was ionized, crackling loudly, and space itself subtly distorted under the terrifying energy!

An extremely terrifying pressure descended! As if the Nine Heavens Thunder God had cast down a judgment prison!

The Vajra Battalion warriors on the training ground grunted, directly forced to their knees by this pressure, their demonic gold armor violently trembling and wailing!

The Worker Bee swarm fell from the sky like dumplings, trembling in fear!

Even the Stone-skinned Turtle let out a low, respectful roar, the demonic patterns on its shell flickering erratically!

Wang Linger’s face was pale. Before this divine Formation, she felt as tiny as dust, her spiritual power completely solidified, unable to muster any thought of resistance!

Moyuan floated in the center of the thunder prison, bathed in the violent thunder light, yet he was as comfortable as a fish in water.

His deep purple Thunder God Arm slightly lifted, feeling the terrifying power from the Grand Formation, which he could command as easily as his own arm.

The Nine Heavens Thunder Hell Formation! Completed!

The Formation’s light gradually converged, no longer dazzling, but the countless surging dark purplish-gold and gray Thunder Dragons did not disappear. Instead, they receded into the rock wall runes, like millions of lurking thunderous Vicious Beasts, ready to unleash a world-destroying strike at any moment!

An invisible, destructive barrier, powerful enough to make Cultivators below the Nascent Soul Rank tremble in fear and their Divine Souls collapse, had completely enveloped the entire Underground Mo City!

Absolute defense! Unbreakable by those below the Nascent Soul Rank!

Moyuan’s cold gaze swept over this underground Dynasty, which he had personally imprinted with the mark of destruction.

“From now on… Mo City… will be impregnable.”

“Intruders… their Divine Souls will be annihilated!”

His voice, like a thunderous decree, was branded deep into the Soul of every trembling Rank being.

Underground Mo City, finally, in the endless thunder, completed its ultimate armament.
