The air inside the cave seemed to solidify into ten-thousand-year-old profound ice, with an invisible killing intent pressing against every inch of space.

The little demons with low cultivation shivered in fear, unable to even scream, their divine souls shattered under the icy will, collapsing limply to the ground.

Thunder Demon surged with crackling electric light, forcefully creating an electric field to resist the pervasive, terrifying pressure.

It stared intently at the black-clad figure that had appeared at the cave entrance, its heart gripped tightly as if by an invisible hand.

"Xu... Xu Guang!" Thunder Demon’s voice carried a faint tremor as it finally recognized the intruder, the very human scourge who had turned the Sea of Mist upside down, sought after by the Azure Dragon Race and Dark Abyss City!

Xu Guang slowly walked into the cave, his steps unhurried, as if he were strolling into his own backyard rather than a demon’s lair.

His gaze swept over the human cultivators imprisoned in cages, their faces filled with despair, lingering momentarily on a few female cultivators whose clothes were slightly disheveled and eyes full of terror, the coldness in his eyes intensifying like a polar storm.

"I’ve heard you can make it so I have no return?" Xu Guang’s voice was calm yet carried a chilling coldness that pierced the divine soul.

Thunder Demon forced itself to remain calm, shouting with feigned confidence, "Xu Guang! Don’t be arrogant! This is my territory! Several Second Nirvana Demon Kings are searching for you; by showing yourself, you’re walking into a trap!"

It was stalling for time because its business involved people, and among the high ranks of Dark Abyss City, there were a few human cultivators—it could only conduct its business outside the city.

At this moment, it was anxiously aware of Xu Guang’s mysterious means of appearing, almost as if merging with shadows; it knew it was no match.

As long as Xu Guang was caught off guard, when reinforcements arrived, the crisis would naturally be resolved, maybe even capturing Xu Guang for great merit.

"Is that so?" Xu Guang’s lips curled into a mocking arc, "Too bad you won’t live to see that day."

Before the words finished, Xu Guang moved.

No earth-shattering momentum, only an afterimage that reached the pinnacle of speed.

Green Emperor’s Body and Black Emperor’s Body did not fully manifest but transformed into two streams of light merging into his body.

The left eye was full of vitality, harboring lethal annihilation.

The right eye was deep azure, controlling the flow of all waters.

"Lightning Prison’s Heaven Execution!" Thunder Demon screamed, knowing it couldn’t wait any longer, unleashing its long-prepared lethal move.

It thrust its hands forward, countless blue lightning as thick as a child’s arm intertwined into a destructive electric grid, that covered the entire cave with a purifying terror, bearing down on Xu Guang!

This was its innate divine technique, confident that not even a peak First Nirvana could take it head-on.

Facing this lightning prison, enough to turn an ordinary First Nirvana into char, Xu Guang merely raised his hand.

In his palm, Vital Killing gathered, surrounding a bloody sun, and he gently clenched his fist towards the sky of thunder.

"Break."

He softly uttered the word, and the bloody sun swiftly turned. All was calm, as if Thunder Demon’s all-encompassing thunder had been a mere illusion.

No explosion, no rumbling.

The violent electric grid vanished silently, as if snow under the sun, when confronted with the bloody sun enveloped by the true intent of Vital Killing.

The demonic power and rules that formed the thunder disappeared, drowned out by the Vital Killing’s essence of time.

"Impossible!" Thunder Demon’s pupils shrank, eyes filled with fear and disbelief.

Its strongest divine technique, broken with such ease?

The bloody sun didn’t lose momentum, seemingly traversing space, appearing instantly before Thunder Demon’s forehead.

The shadow of death loomed over Thunder Demon.

"No! I surrender! I have many treasures! I know Dark Abyss City’s secrets!" it howled desperately, attempting to plead for its life.

Xu Guang’s eyes remained cold, without the slightest ripple.

"The things you mentioned, I can know all the same from your death."

With a wave, a bronze long sword appeared mysteriously behind the bloody sun.

Pshh!

With a soft sound, the bronze long sword pierced Thunder Demon’s forehead.

Thunder Demon’s body stiffened, the light in its eyes quickly dimmed, and the violent electric light around it extinguished as though it lost its source.

Its divine soul, under that sword, was utterly burned by the true intent of slaughter and the Red Lotus Karmic Fire.

This Thunder Eel Demon King, who lorded over Dark Abyss City’s underworld, never understood why the gap between fellow First Nirvana entities could be so vast.

Xu Guang gestured, drawing Thunder Demon’s corpse into the grindstone formed by the Returning Storehouse Divine Technique, its pure electric demonic power ground and absorbed, replenishing his somewhat depleted qi and blood from recent campaigns.

Thunder Demon’s divine soul crumbled, its most memorable things surfacing in Xu Guang’s mind with the grinding of the bloody sun.

Without even glancing at the shivering, miraculously surviving little demons, he waved his hand and sent strands of qi force that precisely broke the chains imprisoning the human cultivators.

"Escape for your own lives."

Leaving these words, Xu Guang’s figure flickered, vanishing from the cave, leaving behind chaos and a group of human cultivators as though waking from a nightmare.

...

"Thunder Demon was also killed!"

"Right in his lair ’Lightning Pavilion’! Killed in one strike!"

"Did Xu Guang leave a message?"

"He did! The same few words— ’The killer, Xu Guang’!"

The news spread like a plague within the territory of Dark Abyss City and beyond, bringing not just shock but a bone-deep chill.

This Xu Guang was elusive, absurdly powerful, ruthlessly efficient, and frighteningly fast.

He seemed like a phantom, lurking in the shadows of the Sea of Mist, specifically hunting down the renowned First Nirvana Demon Kings and Demon Generals.
