The final stage!

Rumble--!

Thunder flashed in the pitch-black space.

White Night's figure landed in front of the fourth palace.

This palace, named the "Venerable Thunder Palace," was completely different from the previous three.

There were no ferocious thunder sculptures; the palace body was pieced together from billions of rhombic thunder crystal shards. Under the refraction of the thunderous light, it shimmered with a seven-colored halo, seemingly dazzling but exuding a sacred pressure that made one's heart palpitate.

Before even stepping through the palace gate, White Night sensed subtle law fluctuations permeating the air. These fluctuations interlocked and operated like precise gears, forming an invisible net of laws.

The next moment.

The palace gate slid open silently, revealing not a massive physical guardian, but a ball of chaotic thunder light suspended in the center of the hall.

Within the thunder light, the trajectories of stars sometimes appeared, and the patterns of exploding thunder sometimes flashed. Countless tiny thunder runes could vaguely be seen forming and dissipating within it, as if nurturing a microscopic thunder universe!

"I am the guardian of the Venerable Thunder Palace, the Core of Thunder Source, in charge of the fragments of the Thunder Law."

An ancient and majestic voice emanated from the chaotic thunder light.

Before the voice faded, the crystal walls of the entire great hall suddenly lit up. Countless law runes surged from the walls, condensing into nineCircular light track (Circular optical track) in mid-air.

Tens of thousands of thunder runes floated on the light tracks. As the light tracks rotated, the runes arranged and combined as if alive, evolving into nine distinctly different thunder forms: some transformed into fine thunder like soft silk wrapping around a finger, some condensed into indestructible thunder crystals, some turned into thunder vortices that devoured everything, and others became thunder shadows that shuttled through space!

"Law: Myriad Thunders Return to Origin."

The Core of Thunder Source lightly uttered. The nine light tracks simultaneously accelerated their rotation, and ten thousand thunder runes suddenly erupted, transforming into nine thunderous torrents of various forms, surging towards White Night with different trajectories, different speeds, and different attributes.

The fine thunder was like silk, specifically breaking through defensive gaps.

The thunder crystals were like spears, carrying unparalleled penetrative power.

The thunder vortex was like a prison, attempting to drag White Night in and crush him.

The thunder shadows were like specters, flickering erratically in space, specifically ambushing from behind!

Even more bizarrely, these thunderous torrents could merge with each other, sometimes transforming into a thunderous storm covering the entire area, sometimes condensing into a thunder needle for a single-point breakthrough. The complexity of the attacks far exceeded the sum of the guardians from the first three stages!

"It truly lives up to its reputation as a 'Source'-level stage, only cleared by three people!"

White Night's eyes narrowed slightly, and he gently stroked the hilt of his Eternal Demon Blade.

Although this guardian had no physical form, it could directly control fragments of the Thunder Law. Its inherent strength far exceeded the scope of ordinary combat power!

But he wasn't flustered in the slightest.

Swish--!

In an instant, as he flicked his wrist, the dark purple blade drew a subtle arc.

This strike did not use violent force, yet the blade's glow moved like a living thing, weaving through the gaps of the nine thunderous torrents. Wherever it passed, those seemingly indestructible thunderous torrents melted like ice and snow meeting the sun.

"Law: Thunder Realm Cage."

Rumble--!

The Core of Thunder Source, sensing its attack was broken, saw the chaotic thunder light suddenly expand threefold. The nine light tracks instantly contracted, trapping White Night in the center.

The runes on the light tracks burned frantically, forming a golden cage composed of law power. The cage bars were covered with reversely rotating thunder patterns; any object touching the cage would be decomposed into its most primitive energy by the law power!

At the same time, a pillar of thunder light containing the attribute of "annihilation" descended from the top of the cage. Wherever the light pillar passed, space rippled and folded!

White Night's lips curved slightly. The Eternal Demon Blade suddenly burst forth with dazzling dark golden light.

The golden afterimages on both sides of the blade became clearer than ever, and even the flowing law patterns on the afterimages could be seen.

He did not directly resist the cage but swung a second strike at an inconceivable angle.

The blade's glow did not attack a physical entity but precisely struck the law nodes between the cage bars.

"Crack."

A faint cracking sound was heard. The seemingly indestructible law cage developed cracks from within, and the reversely rotating thunder patterns instantly became chaotic.

Taking advantage of the cage's loosening, White Night's figure phased through like a ghost, simultaneously backhanding a strike towards the annihilation light pillar above his head.

The moment the blade's glow collided with the light pillar, there was no earth-shattering explosion. Instead, like a drop of water merging into the sea, the dark purple blade's glow directly cut into the core of the light pillar, severing the law chains that formed the pillar.

"Law: Thunder Dao Reincarnation."

Seeing his two attacks easily dismantled by White Night, the Core of Thunder Source got serious.

With an earth-shattering clap of thunder, the chaotic thunder light suddenly contracted into a single point, then violently exploded, transforming into billions of miniature thunder threads!

These thunder threads drifted throughout the great hall like dandelion seeds. Upon landing, they actually took root and sprouted, growing into strange plants made of thunder!

Some bore fruits containing thunderous storms, some bloomed flowers that could release thunder arrows, and some vines would actively entangle nearby targets!

In just a few breaths, the entire great hall had transformed into a vibrant yet deadly thunder forest!

Even more terrifying, "reincarnation" was constantly playing out in this forest:

Thunder flowers withered and became thunder seeds, thunder seeds sprouted and grew into thunder trees, thunder trees bore fruit and then exploded into thunder threads. With each cycle, the power of the thunder would increase, and the law fluctuations would become more intense!

White Night stood in the center of the forest, feeling the constantly strengthening thunder power around him, his eyes still calm.

He took a deep breath, and the Eternal Demon Blade drew a smooth trajectory in his hand. The blade's glow no longer pursued speed and penetrative power but transformed into a spreading dark purple ripple.

Wherever the ripple passed, the growing thunder plants withered rapidly as if encountering their nemesis. The thunder threads undergoing reincarnation were forcibly interrupted, and even the law fluctuations in the air momentarily stagnated!

"Impossible!"

The chaotic thunder light condensed again, and an incredulous voice came from within.

It could clearly perceive that White Night's blade's glow contained an incredibly terrifying power, a power so strong that it could directly interfere with the operation of laws!

Just as the Core of Thunder Source attempted to mobilize deeper laws, White Night moved.

This time, he didn't use complex techniques, but merely infused power into the Eternal Demon Blade, swinging a plain, unremarkable strike towards the chaotic thunder light.

The moment the blade's glow tore through the air, time around it seemed to stretch. The nine light tracks, the thunder forest, and the afterimages of the law cage flashed around the blade's glow, ultimately all anomalies compressed into a single point, piercing into the core of the chaotic thunder light along with the blade's glow!

"Puff--!"

There was no earth-shattering explosion. The chaotic thunder light slowly dissipated like a popped bubble!

At the same time, the operating law runes lost their support, transforming into countless light specks that floated down, like a brilliant fireworks display.

The moment the light specks landed, the crystal walls of the entire Venerable Thunder Palace lost their luster, revealing the simple stone inner walls.

The Game System prompt popped up:
