A single King Golden Gu could repel an ordinary Golden Core cultivator. When four or five King Golden Gu swarmed together, even a high-tier Golden Core cultivator would have to pull back somewhat. Yet, that petite and exquisite mysterious woman merely extended her slender hand and effortlessly captured the invulnerable and eerily agile King Golden Gu. This sight shocked Elder Demon Huyan speechless, and in his fury, he roared incoherently, "Shameless brat! You agreed to a one-on-one fight, what's the meaning of bringing out some woman?"

Lei Dong couldn't be bothered to waste words with him. He pushed the Netherworld Grand Technique to its absolute limit. Centered on him, within a mile's radius, the black ghostly energy was chillingly sharp, not only forming a dense black fog but also weaving into wisps and swirling vortices. The tide-like mass of vengeful spirits, as if injected with stimulants, shrieked at the top of their lungs, using their sharp claws and fangs to battle the swarm of Bone-Devouring Flying Ants.

The Bone-Devouring Flying Ants were also an extremely troublesome type of minute demonic insect in the Nether Realm, prone to hunting and migrating in swarms. Once they reached a certain scale, nothing living or breathing was left in their wake; not a single blade of grass survived. If their numbers reached one hundred thousand or several hundred thousand, even a Ghost King would flee in disarray. Unfortunately, Elder Demon Huyan's swarm of Bone-Devouring Flying Ants amounted to no more than ten or twenty thousand at most, making their imposing display somewhat lacking. Moreover, these flying ants were quite effective against large bodies of flesh and blood, but against an equal number of tangible yet formless vengeful spirits, their power was inevitably greatly diminished, being thoroughly countered.

The vengeful spirits, having absorbed the pure Netherworld Ghost Qi, danced and roamed everywhere, tearing apart and devouring the Bone-Devouring Flying Ants. Meanwhile, Xiao You and A Chou darted back and forth within the toxic miasma cloud. In less than ten breaths, they had captured all the sharp King Golden Gu.

"Old Ugly Man, this young lady and A Chou are this Young Master's ghost servants, so naturally, we are like extensions of his very body." Xiao You, however, was extremely displeased by Elder Demon Huyan's insult toward Lei Dong. She scoffed repeatedly, "Are you saying it's permissible for you to use King Golden Gu for sneak attacks, but forbidden for my Young Master to summon his ghost servants?"

Everyone then realized that the masked young girl and the green-faced, tusked Ghost General were both Lei Dong's ghost servants. As understanding dawned, they were immediately stunned into place. Could it be that the petite and exquisite woman originated from a Supreme Spirit Ghost? And had been carefully nurtured for a long time? Otherwise, she could never possess such spiritual intelligence. Tu Lei's eyes also lit up. In the entire Sky Ghost City, only Tu Lei and the Sky Ghost King originated from Supreme Spirit Ghosts. It was known that even in the Nether Realm, teeming with Dark Ghosts, the number of Supreme Spirit Ghosts was exceedingly small. A sense of kinship often arose between them.

What a pity, what a pity, this Supreme Spirit Ghost girl had already been blood-sacrificed and refined into a ghost servant. Otherwise, given time, she would have become another Ghost King in the Nether Realm.

After deducing this fact, everyone's perception of Lei Dong shifted considerably. That was a Supreme Spirit Ghost, a being with immense potential to advance to a Ghost King. And this Lei Dong seemed quite young, still having the chance to reach the Nascent Soul stage. At that time, relying on this one Supreme Spirit Ghost, he would possess a significant advantage over cultivators of the same rank.

As for whether Xiao You was a Heavenly Spirit Ghost, that was something none of the present company even dared to contemplate. To them, a Supreme Spirit Ghost was already exceedingly rare and precious. A Heavenly Spirit Ghost was something legendary, appearing only once every thousand years on average in the Nether Realm.

Elder Demon Huyan immediately fell silent. Everyone knew that a cultivator's ghost servants were tantamount to their own strength.

However, at the same time, the spreading scarlet toxic miasma cloud began to exert its power. Xiao You and A Chou, being powerful, were momentarily unafraid of the miasma's corrosive effects. But the individual strength of the vengeful spirits was poor; they couldn't withstand it for more than a few breaths before crying out and turning to ash.

"Hmph~"

Xiao You, being a Heavenly Spirit Ghost, was fundamentally far superior in rank to those vengeful spirits, yet they shared the same origin. Seeing the vengeful spirits suffer such heavy casualties, she felt a pang of sadness and heartache. Immediately, she let out a sharp cry, the surrounding space twisted faintly, and then she materialized directly behind Elder Demon Huyan's back. Her fair, slender hand instantly transformed into sharp claws, thrusting toward his heart.

"Spatial Arts?"

Most people present couldn't help but exclaim upon witnessing this. Lei Dong's previous spatial teleportation had clearly relied on the extraordinary wings on his back. But for a ghost servant to deploy spatial arts was terrifyingly unusual. Indeed, almost all Spirit Ghosts, upon awakening sentience and advancing to Ghost Soldiers, would inherently integrate some innate magical techniques from the laws of heaven and earth. But the innate techniques most Spirit Ghosts grasped leaned towards the Profound Yin system of the Netherworld, and they were all very basic, low-level spells.

Only a very few Spirit Ghosts of high rank and good talent could grasp and awaken more complex techniques. This was one reason why higher-ranked Spirit Ghosts were more valuable. However, techniques involving spatial teleportation were laws of heaven and earth on a very high level; even beings who reached the Nascent Soul stage could only grasp the surface level of spatial arts, using them simply.

Typically, only entities reaching the Spirit Transformation stage formally mastered and skillfully employed teleportation techniques. Just like Lei Dong's Asura Wings, which were derived from the wings of an Asura King possessing Spirit Transformation level power. And the reason the Asura King could utilize spatial teleportation was also due to those wings.

Because of this, although the quality of Lei Dong's Asura Wings was only at the Spiritual Artifact level, they uniquely possessed spatial teleportation capabilities. This made the Asura Wings a heaven-defying treasure for low-level cultivators, an excellent artifact for fighting above one's rank and for escaping and preserving life.

But for a ghost servant originating from a Spirit Ghost, even at the Supreme Spirit Ghost level, to grasp the innate technique of spatial teleportation while only at the high-tier Ghost General level was exceedingly rare. At least, Tu Lei, a high-tier Supreme Ghost General, currently knew nothing about spatial teleportation, not having mastered even the basics.

At this juncture, everyone could only sigh at how lucky the Supreme Spirit Ghost named Xiao You truly was. To have stumbled upon the good fortune of mastering spatial arts so early. Such occurrences were not unprecedented in history, just few. But simultaneously, they felt even more jealous, or reverent, toward Lei Dong. No matter how incredibly powerful Xiao You was, she was ultimately this man's servant. The more powerful she became, the stronger Lei Dong’s strength implied.

As for Bei Ye, she had originally believed that Dongfang Fu and Ding Wanyan were the most formidable existences among cultivators of her peer group she had ever seen. She never expected that Lei Dong, only at the early Golden Core stage, would be even more astonishing and exaggerated. Her beautiful eyes gazed at Lei Dong from afar, filled with continuous, sparkling admiration; no one knew what she was contemplating.

However, Elder Demon Huyan managing to carve out such a renowned name meant he was by no means ordinary. His expression instantly sobered, and he transformed into a hazy green smoke, barely dodging Xiao You's fatal sneak attack. But he forgot about the Supreme Ghost General A Chou. Although he was taciturn and not as dazzling as Xiao You, a Supreme Ghost General still could not be underestimated. Under the Bloodthirst Art, his entire body flushed red. He suddenly charged head-on against Elder Demon Huyan.

Poor Elder Demon Huyan only managed to summon a sinister bone shield, but under A Chou's fierce slash, it shattered and cracked, directly damaging Elder Demon Huyan's soul. This forced him to spit out a mouthful of blood. Without a second thought, he urged his green escape light, intending to flee, while simultaneously throwing out two long-cherished Yin Fiend Heavenly Thunders. Having mingled in the Nether Realm for many years, Elder Demon Huyan, when faced with the choice between his life and his pride, cared nothing for face.

Boom, boom~

The formidable completed Yin Fiend Heavenly Thunders forced Xiao You and A Chou to defend with all their might, while he used the opportunity to flee towards the red clouds churning in the sky at extreme speed.

"Trying to run?" Lei Dong sneered twice. This Elder Demon Huyan's strength was decent, and his greed for life made him the perfect candidate for control via Gu beasts. How could Lei Dong let him escape so easily? The Asura Wings on his back lifted high, and with a powerful flap, he instantly teleported to intercept, blocking the old demon’s escape route ahead of time.

"Roar~"

A gigantic fierce tiger, already five or six zhang long, manifested majestically. It roared once and spat out a sphere of light toward the green light.

"Damn it." Elder Demon Huyan's face turned green. Unable to dodge in time, he spat blood to prop up a green light shield. Under the violent collision with the light sphere, he couldn't withstand the impact and was sent tumbling backward in retreat.

After defending against the explosion of the Yin Fiend Heavenly Thunders, Xiao You, though unharmed, was utterly disheveled. Her beloved green dress was tattered and torn. This naturally enraged Xiao You, who pursued him closely. Mimicking Lei Dong, she began savagely beating the cornered foe. While striking, she cursed, "You ugly old man! How dare you throw Heavenly Thunders at this young lady! Don't you know this Emerald Silk Skirt was meticulously chosen by my Young Master?"

Although Xiao You was petite and exquisite in stature, her strength, originating from a Heavenly Spirit Ghost, should not be underestimated. Even in a pure contest of strength, A Chou, who preferred close combat, was slightly inferior to her. With every punch and kick, she beat Elder Demon Huyan until his bones cracked, making him spew mouthfuls of blood. He didn't dare fight back for fear that she would beat him to death, instead throwing away all pretense and miserably begging, "Little Ancestor, I was wrong! I shouldn't have thrown the Heavenly Thunders at you. Please, be magnanimous and spare me this once!"

Xiao You and Lei Dong shared a single mind; she naturally knew her Young Master's needs. Just beat him until he submitted, beat him until he was terrified, but do not take his life. She also knew that despite Elder Demon Huyan's shabby appearance, he was still a high-tier Golden Core figure with formidable vitality. She kept punching and kicking, thoroughly enjoying the process, excitedly saying, "Young Master is absolutely right, beating people with fists is truly satisfying."

Lei Dong, from the other side, had a darkened expression and sucked in a sharp breath. His ghost servant Xiao You usually appeared so gentle and docile. Who knew that deep inside she harbored such a dark, violent side? Lei Dong began to sympathize with the already inhuman Elder Demon Huyan.
