The winged youth's expression turned grim, a bone-chilling cold light suddenly shooting from his eyes, and an intensely mournful killing intent slowly permeated from his grey wings.

Gently beating his grey wings, this winged youth did not hurry, slowly approaching Shi Yan.

Halfway there, sharp blades of wind suddenly materialized, each one glittering brilliantly and dazzlingly, containing an astonishing power of the wind.

"Human brat, I will make your life a living hell! Those who offend Han Long will never get a peaceful death." The winged youth flapped his wings, and streams of wind-blades howled out, appearing as piercing streaks of crystalline light in the void, vanishing in a flash.

Behind him, the other two winged youths also wore cold, sinister expressions, flanking the main winged youth.

All three winged youths possessed cultivation at the Diwei Realm. The leader, Han Long, had a slightly superior cultivation, perhaps at the Second Heaven of the Diwei Realm. His physique was robust, imbued with explosive power, as if he would launch forth like a javelin with the slightest movement.

"Good, you've come!"

Under the assault of the wind-blades, Shi Yan smiled faintly, showing no surprise, and even let out a loud shout before leisurely shifting his body.

Swift as lightning, under the killing strikes of the wind-blades, Shi Yan swiftly darted away, effortlessly evading the sharp swords condensed from the power of the wind.

"Is that all you've got?" Shi Yan hadn't even activated Berserk Mode, borrowing not a shred of Negative Energy. "If this is all you can manage, then you're in deep trouble this time."

"Han Long!" Yi Cui Bi's delicate face changed slightly, her beautiful eyes filled with astonishment. "You are Han Long, the youngest son of the Grey Wing Clan Chief?"

"Human brat, you will undoubtedly die." The winged youth ignored Yi Cui Bi, slowly drawing a breath as if to quell the anger in his heart. "I will capture you alive and take you back to our Grey Wing Clan to taste the pleasure of being violated by a **ape."

The two winged youths beside him chuckled upon hearing this, their faces bearing knowing, strange expressions.

"You have rather peculiar tastes. Do you often engage in that sort of activity with **apes?" Shi Yan adopted an expression of utter disbelief, then suddenly understood, clapping his hands and laughing heartily. "Ah, right, you bird-people are also hybrids, so doing that with **apes is quite suitable. It’s I who was making a fuss over nothing."

"Bang!" A muffled sound of air exploding suddenly erupted from behind the Grey Wing youth named Han Long; the speed of his grey wings beating accelerated sharply.

Like an arrow loosed from a bow, Han Long lunged toward Shi Yan, his expression sinister, his eyes filled with venomous malice.

Gale-force winds howled, and two peculiar secret treasures resembling silver talons swayed menacingly in his hands, emitting a dazzling silver light filled with intense sharpness, seemingly capable of destroying anything.

Simultaneously, the Grey Wing youth's muscles bulged, dense vital energy surged rapidly throughout his body, ferocious and overwhelming.

At this moment, Han Long was thoroughly enraged, determined to strike a blow that would see Shi Yan killed on the spot.

Shi Yan narrowed his eyes slightly.

Faint wisps of ash-grey smoke quietly drifted out from his pores, carrying with them emotions of despair, brutality, and bloodlust, gathering behind him.

A strange aura of wickedness, coldness, and resentment suddenly intensified. The ash-grey smoke quickly coalesced into clusters, condensing into the phantom image of a ferocious and terrifying demon.

The Materialization of Negative Energy.

This was a unique offensive technique Shi Yan had developed himself, utilizing the lingering Negative Energy swirling within his body to condense a demonic phantom existing between illusion and reality. Because this demonic phantom was saturated with so much Negative Energy, it was, in a sense, granted a form of life.

Once formed, the demonic phantom not only carried astonishing Negative Power but could also assault the opponent with various negative emotions, causing their consciousness to falter, making them easily permeated by the Negative Clarity and instantly losing their resistance.

"What is that thing!"

As the demonic phantom emerged, the three Grey Wing youths gasped in unison.

Yi Cui Bi's delicate face shifted slightly, and she quietly retreated a distance, creating space between herself and the phantom.

The Yin Charm Clan possessed special souls, and Yi Cui Bi had profound attainments in soul cultivation. The moment the demonic phantom appeared, she sensed its extreme strangeness—within a body composed purely of some special evil energy, there were layers of emotional fluctuations.

Such a peculiar entity seemed to possess an evil life, filled with a craving for bloody slaughter.

"Break!" Shi Yan roared, raising both hands in a void gesture. The Life and Death Seal materialized amidst a dazzling glow and was abruptly thrust out.

Han Long’s strange secret treasures, the silver talons, blasted out streams of extremely fierce silver light, like silver ribbons lashing out toward Shi Yan's body.

But at the instant the Life and Death Seal erupted, all the silver light converging on Shi Yan shattered instantly, dissolving into flecks of silver that vanished immediately.

The Life and Death Seal, tearing through resistance like dry rot, first pulverized the silver threads into dust, then surged onward, aiming directly for Han Long’s chest.

Han Long’s expression changed dramatically. His rapidly moving body halted abruptly in mid-air. The violent vital energy within his body suddenly surged; his wings flapped rapidly, and the howling gales intersected, actually forming a visible vortex of wind.

The fierce strike of the Life and Death Seal, its momentum undiminished, plunged directly into the vortex. Then, muffled explosions sounded one after another. The vortex was ripped apart in the detonations, unable to sustain itself, and vanished instantly.

"Kill him!" Han Long's eyes, like a viper's, were fixed on Shi Yan. The moment the vortex dissipated, he rapidly retreated.

The other two winged youths charged towards Shi Yan, one from the left and one from the right. Han Long retreated to avoid the residual shockwave of the Life and Death Seal, then flew back toward Shi Yan, his killing intent extremely sharp.

"Shi Yan, he is the son of the Grey Wing Clan Chief, you... you..." Yi Cui Bi couldn't help but cry out, seemingly trying to stop Shi Yan from continuing his assault.

"Go!" Shi Yan didn't spare Yi Cui Bi a second glance. He pointed a finger at Han Long, and the massive demonic phantom hovering behind him suddenly floated out like a ghost, extending its sharp claws and baring its fangs to tear at Han Long.

"Bang!" Blooms of crimson flames suddenly burst forth from his palms, the flames winding around his fingers, writhing like earthworms.

"Let's burn off your bird feathers first." Shi Yan waved his hand casually. Streams of flame flew from his palm, enveloping the two approaching winged youths.

"He is the son of the Friendly Wing Clan Chief. Shi Yan, you won't gain anything from this. Forget it, let's leave now."

Yi Cui Bi urged anxiously.

"Bitch, you won't live either!" Under the demonic phantom, Han Long was still rampant, sneering wickedly. "Those who offend Han Long will suffer a fate worse than death!"

"Bird-people are just bird-people; their intelligence is limited."

Shi Yan shook his head, his gaze gradually turning cold. With a shift of his mind, the demonic phantom lunged at Han Long, and the surging Negative Energy instantly spread out, enveloping Han Long’s body directly.

"Hiss! Hiss! Hiss!"

Amidst agonizing screams, the two Grey Wing youths touched by the Heavenly Fire flames had the grey wings on their backs erupt in towering flames. They shrieked wildly, and the strength within them gradually receded.

"If they are all dead, there will be no future trouble."

The surging flames, like rolling clouds, suddenly billowed toward the three Grey Wing youths. Amidst Yi Cui Bi's horrified cries, the three winged youths were rapidly engulfed by the Heavenly Fire.

That demonic phantom had silently returned and was gradually vanishing beside Shi Yan.

The Heavenly Fire burned fiercely. The three Grey Wing youths stopped screaming amidst the flames. In just a few seconds, their bodies were incinerated to ashes and scattered by the wind.

Not even their essence remained.

Shi Yan was momentarily stunned. He closed his eyes, sensed the aftermath, and then shook his head with regret, thinking that he should use Heavenly Fire less in combat in the future, otherwise, he would gain nothing.

The ashes dissipated, and the three Grey Wing youths vanished from sight.

Yi Cui Bi’s clear, captivating beautiful eyes were filled with terror. She stared blankly at the ashes swirling in the air, suddenly feeling a chill wash over her.

"Howl! Howl!"

From the Yin Beast Mountain ahead, numerous Yin Beasts suddenly roared the moment the Heavenly Fire appeared.

Many Yin Beasts that had charged down from the mountain trembled at the roars and hurriedly flew back, retreating from the foot of the mountain and hiding within the Yin Beast Mountain once more.

Higher-level Yin Beasts sensed the aura of destruction from the Heavenly Fire. Through their roars, they called their subordinates and descendants to evade Shi Yan’s incineration.

Soon, all the Yin Beasts that had emerged from the Yin Beast Mountain retreated.

Midway up the Yin Beast Mountain, several massive demonic beasts with distant auras gazed toward Shi Yan with strange eyes, showing expressions of deep dread.

Evidently, even these Yin Beasts knew fear and understood the terrifying might of the Heavenly Fire.

"You... you killed Han Long. You actually killed Han Long."

Yi Cui Bi murmured in disbelief, her expression complex and her astonishment unresolved. "Han Long is the son of the Grey Wing Clan Chief. The Grey Wing Clan is one of the three branches of the Wing Clan, and their Chief is notoriously warlike and fiercely protective of his own. If he learns Han Long is dead, he will surely go mad."

"All three are dead, so the message won't leak out," Shi Yan smiled. "That guy wanted to kill me; naturally, I couldn't just wait to be slaughtered. Killing him was clean and swift. Hmm... I suspect that while I am here, the Yin Beasts of this mountain probably won't venture out for a while. Why don't we take cover first, and when the beasts come down from the mountain, we can resume our hunt?"

"I hope so."

Yi Cui Bi sounded uncertain. "The Wing Clan is very weak in soul cultivation. Perhaps he can discern Han Long’s death, but he might not know who killed him. Let's hope... let's hope he doesn't discover the true cause of Han Long's death, otherwise, not only will you suffer, but even our entire clan will face his wrath."

"Whoosh! Whoosh!"

The sound of beating wings suddenly came from behind the distant Yin Beast Mountain. This time, the sound of wings slicing through the air was very dense, meaning more winged people were likely arriving from behind the mountain.

"Quick, let's go!"

Yi Cui Bi’s face changed. She grabbed Shi Yan and pulled him away, speeding toward the direction of the giant stone ancient city.
