Upon hearing these words, the people from the Nine Yin Demon Sect, whose bodies had been trembling uncontrollably, suddenly stopped trembling as if they had been frozen in place.

The fear that had filled their faces gradually disappeared, replaced by an expression of relief, as if this person was their lifeline.

Just then, a tall, black-clad old man with black markings on his face suddenly appeared above Yuan Zhexian like a ghost.

Upon seeing the old man, the members of the Nine Yin Demon Sect bowed and clasped their hands, shouting in unison, "Greetings, Ancestor Li Xin!"

Ancestor Li Xin stared at Yuan Zhexian with a gloomy expression, his eyes filled with endless hatred. He stared intently at Yuan Zhexian and said through gritted teeth, "You bastards, how dare you kill my junior brother!"

"Today, I will make you pay the price! I will turn all of you into my nourishment, then extract your souls and temper them with the Nine Yin Fire for endless years, making you suffer endless torment!"

After saying that, a sword-shaped magic weapon radiating black demonic energy suddenly appeared in the hand of Ancestor Li Xin. His aura also exploded instantly, and a terrifying energy belonging to the third level of Earth Immortal swept over like a raging storm.

He placed the sword-shaped magic weapon in front of him, his hands constantly forming hand seals, and he loudly chanted, "Abyss of Yin Demons!"

As the words of the ancestor Li Xin fell, a chilling black demonic energy, like a ferocious beast, roared and churned, rapidly coalescing into a massive black demonic energy tornado.

This demonic tornado, like the end of the world, swept straight toward Yuan Zhexian with endless darkness and destructive power.

Yuan Zhexian remained unmoved, his figure appearing so small amidst the terrifying tornado of demonic energy.

In the blink of an eye, the demonic tornado enveloped Yuan Zhexian at an astonishing speed.

In an instant, heaven and earth trembled, as if the entire world was about to be torn apart by this powerful force.

Immediately afterwards, as if drawn by a mysterious force, Yuan Zhexian plunged straight into the ground, leaving behind only a bottomless, enormous hole, as if it were the entrance to hell.

Upon witnessing this scene, Sheng Qingzhou and the others turned deathly pale. They stared in terror at the bottomless pit and cried out in unison, "Great Ancestor!" Their voices were filled with despair and fear.

Upon seeing this, the ancestor Li Xin was first taken aback, then burst into a wild laugh: "Hahahaha! No one has ever survived being afflicted by my Yin Demon Abyss. From now on, you will be plunged into endless depravity, hahaha!"

However, before his laughter had even subsided, Yuan Zhexian's figure, like a ghost, slowly floated out of the bottomless, enormous cave.

Ancestor Li Xin's laughter abruptly stopped. He stared wide-eyed at Yuan Zhexian in disbelief, muttering, "How...how is this possible? How could you still be alive?"

Yuan Zhexian's lips curled up slightly, revealing a disdainful sneer. He mocked, "Ignorant ants!"

After saying this, Yuan Zhexian closed his eyes tightly, paused for a moment, and then suddenly opened them.

In an instant, his eyes shone with a dazzling double pupil, like stars, radiating a light that made one's heart tremble.

Immediately afterward, Yuan Zhexian parted his lips slightly and whispered, "Light of Destruction!"

These four words seem to contain boundless power, like a thunderbolt, awe-inspiring and terrifying.

As he finished speaking, Yuan Zhexian's eyes suddenly flashed with a dazzling purple light, like the dawn before sunrise, piercing the darkness and illuminating the entire space.

Immediately afterwards, the purple light shot out like lightning, forming a purple beam that rushed straight toward the ancestor Li Xin with lightning speed.

Upon sensing the terrifying power of this destructive light, Elder Li Xin's expression changed drastically, and he exclaimed in astonishment, "What kind of eyes are these? How can they possess such power?"

His voice was filled with disbelief and fear, clearly overwhelmed by Yuan Zhexian's sudden and powerful strength.

However, despite being shocked, Li Xin's actions did not stop.

He quickly mobilized his ultimate power, and all the true essence in his body gathered in his hands like surging waves.

His hands moved with lightning speed, forming hand seals, each one containing endless mystery and power.

"This is the vengeful spirit I've refined from the countless people I've slaughtered on planets! Die!"

"A vengeful spirit!"

Ancestor Li Xin roared, and as his words fell, a blood-red magic array, like the gates of hell, suddenly appeared in his hand.

This magic array emanated endless resentment, as if it were the roars and cries of countless wronged souls.

Immediately afterwards, countless vengeful spirits pounced on the beam of destructive light like hungry wolves.

They bared their fangs and claws, their faces contorted in a ferocious grimace, filled with endless resentment and murderous intent, as they collided violently with the light of destruction!

At the very moment the two collided, the light of destruction pierced through countless spirits with overwhelming force.

Finally, the arrow struck straight at the ancestor Li Xin.

Ancestor Li Xin stared wide-eyed, his face filled with disbelief. He watched helplessly as his body slowly turned into nothingness under the erosion of the light of destruction.

Fear surged through him like a tidal wave. He opened his mouth, but found he could no longer make a sound. He could only watch helplessly as his body gradually dissipated into the world, eventually turning to ashes.

Those members of the Nine Yin Demon Sect who were lucky enough to survive witnessed this scene and were terrified. They were completely overwhelmed by this terrifying power and immediately wanted to flee this horrible place.

However, how could Yuan Zhexian let them escape so easily?

Yuan Zhexian let out a cold snort, and an extremely terrifying pressure swept over like a tidal wave, instantly enveloping everyone in the Nine Yin Demon Sect.

This oppressive force was like Mount Tai pressing down, making it impossible for the Nine Yin Demon Sect experts to move or even breathe.

Just then, Yuan Zhexian suddenly turned around, his gaze sharp as torches, staring intently at Sheng Qingzhou, and shouted sternly, "Kill! Leave no one alive!"

His voice, like thunder, echoed through the space, making everyone's eardrums buzz.

Upon hearing Yuan Zhexian's order, Sheng Qingzhou's shock subsided somewhat, and he quickly cupped his hands in response, "Yes, Your Majesty!"

Immediately afterwards, nearly a hundred experts from the Tianyan Sword Sect pounced on the Nine Yin Demon Sect experts who were unable to move due to the oppressive aura of Yuan Zhexian.

These powerful experts from the Heavenly Evolution Sword Sect were incredibly strong, and dealing with the Nine Yin Demon Sect experts who were being suppressed and had no chance to fight back was a piece of cake for them.

The longswords in their hands gleamed with a cold light, and every swing of the sword was accompanied by a splash of blood. The powerful members of the Nine Yin Demon Sect were powerless to fight back in this terrifying massacre and could only be slaughtered at their mercy.

In less than half a day, all the powerful members of the once invincible Nine Yin Demon Sect perished without exception.
