These five major families each occupied a vast territory, and each had a Demon Venerable powerhouse presiding over them.

Among them, the Giant Demon Clan’s overall strength was the most formidable, while the Bone Demon Clan was the weakest of the five families.

Fang Hong’s current location was precisely the territory of the Bone Demon Clan, specifically a small city within the "Black Domain," one of the Bone Demon Clan’s three major regions.

The middle-aged man in black he had just killed was the City Lord of this small city.

The Bone Demon Clan’s territory was clearly divided into three major regions: the Heaven Region, the Eternal Region, and the Black Domain.

Each region had a Demon Venerable Old Ancestor with profound magic power presiding over it, managing all affairs within that region.

Each region was further divided into over a hundred provinces, each controlled by a powerful Immortal Emperor level expert.

Divided layer by layer, the grade was strict and order was well-maintained.

After learning of these circumstances, Fang Hong couldn’t help but sigh inwardly.

The strength of the Heavenly Demon Realm truly lived up to its reputation; even the Bone Demon Clan, the weakest of the five families, possessed so many Immortal Emperor level powerhouses.

The depth of the foundations of the other, even stronger families could only be imagined.

However, the more Immortal Emperor level powerhouses there were, the happier Fang Hong felt.

To him, these Immortal Emperor level Ancient Demons were the best materials for refining high-grade dao pills, perfectly meeting his needs for accumulating resources.

As for how strong the Demon Venerable Old Ancestor presiding over the Black Domain was, the slain City Lord’s grade was too low to know.

To find out the specific cultivation level of this Demon Venerable Old Ancestor, he would likely have to capture an Immortal Emperor level Ancient Demon to obtain accurate intelligence.

Subsequently, Fang Hong once again activated the power of the void ring. With a thought, his figure vanished into thin air from within the hall, heading toward his next destination.

In an instant, Fang Hong’s figure appeared in the sky above another city.

The scale of this city was over a hundred times larger than the small city from before.

The city was surrounded by towering black walls that reached into the clouds.

Mysterious demon runes flickered on the city walls, emitting a powerful protective aura.

This was the location of the Provincial Governor’s Mansion of a certain province in the Bone Demon Clan, and it was also the core city of the entire province, gathering most of the province’s powerhouses.

Fang Hong quietly swept the city with his Divine Sense, and in just an instant, he accurately located the place where the Provincial Governor was in secluded meditation.

Deep within an Immortal Cave inside a mountain peak at the center of the city,

this Provincial Governor was an old man wearing a purple robe, with white hair and beard, looking incredibly aged.

However, he was surrounded by extremely thick demonic qi, and his cultivation had reached the Immortal Emperor Late Stage, with strength far exceeding that of the previous small City Lord.

At this moment, the purple-robed old man was sitting cross-legged on a stone bed deep within the Immortal Cave.

He was fully immersed in his secluded Cultivation, completely unaware that Fang Hong was probing him with Divine Sense.

Following his usual procedure, Fang Hong once again activated the power of the void ring.

With the enhancement of the void ring, he directly ignored the layers of protective formations outside the Immortal Cave and appeared silently inside the purple-robed old man’s cave!

The sudden spatial fluctuation caused the purple-robed old man, who was immersed in cultivation, to instantly detect an anomaly.

He snapped his eyes open, and two sharp demonic lights shot out from his gaze.

When he saw a burly Black Bear suddenly appear in his cave out of thin air, he couldn’t help but be startled, his face filled with shock and vigilance.

The purple-robed old man was, after all, an Immortal Emperor powerhouse who had experienced countless battles; after the brief shock, he reacted immediately.

Without redundant words, the demonic power within his body erupted instantly, like a surging black torrent, filling the entire cave.

At the same time, he flipped his right hand, and a black dagger flashing with a cold, eerie light appeared in his palm.

His figure blurred as he lunged toward Fang Hong at high speed!

The purple-robed old man’s speed was astonishingly fast, leaving a blurry afterimage in the air, and his entire demonic power was concentrated on the dagger.

But unfortunately, just as the dagger was about to pierce Fang Hong’s chest, it stopped dead in mid-air, unable to advance even a fraction of an inch!

The purple-robed old man’s expression changed, and he exerted all his effort to urge the demonic qi in his body, trying to continue the thrust.

However, he found that there seemed to be an invisible and intangible wall of bronze and iron in front of him; no matter how much force he applied, he couldn’t budge it in the slightest.

What horrified him even more was that he suddenly discovered his body was firmly frozen by a mysterious force.

None of his limbs could move, and even the circulation of demonic qi in his body became sluggish.

He could only maintain the posture of lunging with his blade, suspended in mid-air, his face full of terror.

"You... who are you?"

"I am a Demon Emperor Elder of the Bone Demon Clan! You dare to move against me? Are you not afraid of inviting the sky-toppling wrath of my race’s Old Ancestor?"

The purple-robed old man turned pale with fright and threatened Fang Hong in the Ancient Demon language.

Fang Hong remained expressionless, completely ignoring his threat. He simply reached out, pressed his hand onto the purple-robed old man’s head, and directly performed a Soul Searching Technique.

"Ah. Aaaaah."

A shrill, miserable scream exploded within the Immortal Cave.

The purple-robed old man’s eyes rolled back, his pupils dilated, and his body twitched violently and uncontrollably.

After a while, Fang Hong slowly withdrew his palm, and the purple-robed old man collapsed to the ground like a pile of mud, his aura completely gone.

A smile appeared at the corner of Fang Hong’s mouth; through the purple-robed old man’s memories, he had finally figured out the core situation of the Bone Demon Clan.

The Demon Venerable Old Ancestor of the Black Domain was named "Gu Hei," and his cultivation was only at the Heavenly Venerate Early Stage.

To him, this was simply fantastic news.

With his current strength, dealing with a Heavenly Venerate Early Stage Demon Venerable was completely within his capability.

"A Heavenly Venerate level dao pill." Fang Hong murmured softly, a flash of eagerness in his eyes.

He immediately made up his mind to head to the Black Domain at once, find Gu Hei, kill him, and throw him into the Demon Gourd to be refined into a Heavenly Venerate level dao pill.

The efficacy of a Heavenly Venerate level dao pill was more than a grade higher than that of an Immortal Emperor level dao pill, and the pure energy it contained was unimaginable!

The Bone Demon Clan had a total of three Old Ancestors. Besides Gu Hei of the Black Domain, the other two were named "Gu Tian" and "Gu Heng," presiding over the Heaven Region and Eternal Region respectively.

Among the three Old Ancestors, Gu Hei’s strength was the weakest, being only at the Heavenly Venerate Early Stage.

Gu Heng was next, with a cultivation reaching the Heavenly Venerate Middle Stage.

And Gu Tian’s cultivation was the highest, having already reached the Heavenly Venerate Late Stage.

Fang Hong calculated inwardly; with his current strength, dealing with Gu Hei was more than enough.

But facing Gu Heng and Gu Tian, he did not yet have absolute certainty of killing them.

Rather than risking facing several powerful enemies at once, it was better to first deal with the weakest, Gu Hei.

Once he advanced to the Heavenly Venerate realm in the future, it wouldn’t be too late to come back and deal with the other two Old Ancestors.

Wasting no time, Fang Hong once again activated the void ring and vanished from the cave, heading toward the Black Domain headquarters.
