Chapter 537: The Subtle Uses of the Six Desires Demon Map, Wanderer

The missing upper part mainly contains content from the Qi Condensation to Nascent Soul stages. Logically, a complete inheritance should encompass various supporting divine abilities, secret techniques, and artifact refining diagrams.

However, the legacy of the Ancient Devil of Slaughter has two facets.

It is divided into two ancient scriptures for the Soul Transformation stage: "Soul - Rakshasa" and "Heart - Asura." Only when both are combined does it form the complete inheritance bestowed by the Ancient Devil of Slaughter. As for the part concerning Nascent Soul cultivation secret methods,

the Rakshasa scripture contains none of it.

Therefore, Wang Yu held great expectations for the *Ultimate Desire Demonic Art*. For the Nascent Soul to grow, corresponding cultivation secret methods are absolutely essential.

This was absolutely one of the first problems he needed to address.

Furthermore, Nascent Soul cultivation secret methods also have a concept of compatibility. Theoretically, if Wang Yu could find the Frozen Devil's inheritance, it would be the most suitable cultivation method for him.

However, since the Frozen Devil was sealed by an immortal in the endless ice plains, it has never broken free. Related records are extremely scarce, and its followers are few and far between.

It remains like a cold statue, eternally suppressed beneath the ice mountain.

Regarding the issue of demonic corruption from ancient devil inheritances, ever since experiencing the demonic corruption of the Ancient Devil of Life, Wang Yu believed this ability could be suppressed by his Lapis Lazuli Heart Realm.

As long as it did not exceed his tolerance limit,

cultivating more ancient devil inheritances should not pose a problem.

As time passed, Tian Yuzi led everyone to the Ancestral Hall of the Joyous Union Sect. There, he solemnly retrieved a tortoise shell fragment from beneath the sculpture of the Desire Demon Ancestor, located in the very center.

A complete cultivation method was inscribed upon it in demonic script.

What appeared to be only a few dozen characters could, in fact, be deciphered into different combinations. Each combination expressed a completely different meaning, with every character acting as a high-quality compressed information packet.

Whether one could comprehend the complete inheritance from it depended entirely on the cultivator's personal insight.

Wang Yu, satisfied, received the tortoise shell fragment from Tian Yuzi.

“In addition to the *Heavenly Demon Art*, bring out your sect's Nascent Soul cultivation methods as well, for my spirit companion and disciple to choose from.”

“This… very well!”

Tian Yuzi then retrieved several psychic jade slips from beneath the other ancestral sculptures and handed them to the eagerly awaiting Xue Yu.

Xue Yu, as if no one else was present, spoke to Dou Zhao.

“Little Zhao’er, come quickly and choose. Your future progress will depend on selecting a suitable cultivation method.”

Dou Zhao's expression turned resentful, and she rolled her eyes at the little fox.

She secretly transmitted a message.

“You intend to cultivate with Master?”

“Oh, you little girl, your words are so harsh! What ‘cultivate with’? This is the Grand Dao of Yin-Yang Harmony! Even ancient human emperors were masters of this path, what’s so difficult to speak of?!”

Though Xue Yu usually appeared dim-witted, whenever something piqued her interest, she could argue a point back to life.

Indeed, dual cultivation with Wang Yu benefited them far more. For Wang Yu, it resulted in only a negligible increase in magical power, less efficient than a single day in his "placement slot."

Overall, however, it was still slightly faster than his individual cultivation. He considered it a seasoning in his arduous cultivation life, a way to occasionally relax.

Following the guidance of instinctive desires is actually a good way to cultivate one’s state of mind and preserve health. Sleeping when tired and eating when hungry, as long as it doesn't lead to obsession or madness,

it could even nourish one's vital essence.

The journey to the Joyous Union Demonic Sect was eventful but ultimately safe. All objectives were accomplished, and after acquiring the desired inheritance, it was time to part ways once more.

Dou Zhao would be heading to the Ancient Beast Ancestral God Mountain of the Northern Demon Clan.

With his name protecting her, the old Azure Dragon Demon Venerable would not trouble her. As for why he still sought new Nascent Soul cultivation secret methods despite having acquired the *Heavenly Demon Art*,

it was purely a matter of compatibility. The more such cultivation methods Wang Yu possessed, the greater his theoretical foundation. At the opportune moment, he could then create a Nascent Soul cultivation method perfectly suited to himself.

Thus, similar to how he amassed Dharma Manifestation divine abilities in the past,

he never felt he had too many such top-tier cultivation secret methods. Concurrently, Wang Yu gifted Dou Zhao a batch of resources from his Sea Heart Ring that he no longer needed.

He also gave her a recently refined Longevity Blood Infant Pill.

This item was sufficient to be a breakthrough elixir, assisting her in forming her Nascent Soul. Elixirs refined via the Human Elixir Dao could achieve almost any desired effect. The sole prerequisite was strict adherence to raw material specifications.

In this regard, Wang Yu could only offer limited assistance.

Whether she could thrive depended entirely on her own capabilities.

And so, master and disciple parted ways once more.

One month later,

Southern Chiyuan, at the heart of the Underworld Mountain Sect's domain – the Chaotic Ancient South Sea Islands – officially welcomed the arrival of Wang Yu.

He had gathered numerous secrets about the Netherworld Secret Realm from various channels. Rumor had it that this secret realm was likely an inheritance left by an ancient overlord sect of the Demonic Dao from the early ancient times.

This sect, known as the Demonic Heart Sect, collapsed during its second generation. Its first sect leader was a Soul Transformation cultivator who achieved his breakthrough as a rogue practitioner, but later perished silently due to unknown reasons.

The lineage was passed down only to the second generation before being annihilated by hostile forces.

A great pity.

The Profound Yuan Demonic Embryo Secret Method was a unique technique created by this Demonic Heart Venerable. He was likely an inspiring individual whose innate talent was limited.

The Netherworld Secret Realm belonged to the Underworld Mountain Sect. In earlier years, the Nine Evils Sword Monarch secretly infiltrated it under a hidden identity. After extracting the greatest benefits, he destroyed the secret realm's inheritance mechanism before departing.

This ultimately led to the creation of today’s Netherworld Ruins.

Plum Rain Island in the South Sea was Luo Clan territory. Its former master was the Ancient Beast True Monarch Wang Yu had encountered in the Heavenly Palace Secret Realm. After the family’s pillar fell, only two or three early-stage Nascent Soul cultivators remained to guard the Luo Clan’s maritime domain.

To this day, they found it increasingly difficult to sustain themselves, and the scope of their influence had significantly shrunk.

On Plum Rain Island, the former secret realm entrance had become extremely unstable due to the Heaven-Earth Collapse disaster. The entire Netherworld Secret Realm had "burst" forth from its alternate dimension.

The ruins now almost entirely filled the eastern part of the island.

As Wang Yu had no intention of engaging with the local powers, he entered this area directly. During his journey over the past month, he had also been diligently studying the tenets of the *Ultimate Desire Demonic Art*.

Not much of its content interested him.

One was the Nascent Soul cultivation secret method, the "Mortal Desire Fire Burning God Method." Its core tenet involved collecting all desires from the mortal realm, condensing them into a "fire seed," and then forging one's Nascent Soul through this fire to achieve enhancement.

Simultaneously, it involved comprehending the natural laws of the Path of Human Desire.

The deeper one's comprehension, the more effective the desire fire would be in forging the spirit, and the quicker one would recover. Without other cultivation methods, this technique was best suited for cultivation in the mortal world.

Of course, Wang Yu also had a clever workaround.

Directly absorbing the malevolent thoughts of outer heavenly demons and using their malicious desires to ignite the fire of desire to temper his Nascent Soul. While this method greatly enhanced efficiency, the Nascent Soul could easily be damaged by overly intense desire fire.

It was crucial to remember that the Nascent Soul was a cultivator's very foundation.

Once severely injured, one's cultivation could regress, or, at worst, one could perish instantly. One of the drawbacks of demonic cultivation methods was their extreme danger. Of course… if one safely navigated the perils, the rewards far, far surpassed those offered by orthodox paths!

Currently,

Wang Yu was studying a precious elixir capable of restoring the Nascent Soul. He planned to combine it with this method for daily cultivation and had not yet begun his first session.

In fact, the 'placement slot' could circumvent such dangers.

After all, the 'Wang Yu' within the placement slot would bear the cost, allowing him to simply enjoy the results. However, the placement slots were severely limited.

Out of eight slots, four were occupied by foundational cultivation methods.

He also needed to continue advancing his Dharma Intent and Soul Transformation divine abilities. Especially the latter, as he had been stuck at a bottleneck for some years due to realm limitations. His recent breakthroughs presented an excellent opportunity to achieve successive breakthroughs in these areas.

Those meant for perfection should be perfected; those meant for mastery should be mastered!

It would only take a few years and wouldn't cause significant delay. Once his divine abilities reached their peak, it wouldn't be too late to place the Nascent Soul cultivation method there. For now, Wang Yu's primary goal was to enhance his combat strength.

Moreover, many other methods awaited his iterative advancement!

Some of the artifact refinement methods for spiritual treasures within the *Ultimate Desire Demonic Art* were also quite interesting. Wang Yu was particularly interested in a fifth-tier spiritual treasure named the "Six Desires Heavenly Demon Map."

It required only three main refining materials:

Northern Abyss Silkworm Silk, Tears of Seven Emotions and Six Desires, and Ten Thousand Devil Hide!

Northern Abyss Silkworm Silk was a fifth-tier spiritual material produced by the Northern Abyss Divine Silkworm. This material had long been extinct, but some was still preserved in the treasure vault of the Refined Heaven Demonic Sect.

Beyond that, it might only be sealed within certain ancient and powerful ruins.

Tears of Seven Emotions and Six Desires were tear-shaped treasures condensed from intensely concentrated seven emotions and six desires. The Joyous Union Demonic Sect was indeed prolific in producing this item, but its grade rarely met the required standard.

It was estimated that even if fifth-tier desire tears existed, their quantity would be exceedingly rare. However, it was a tangible item that could be sought after.

Ten Thousand Devil Hide, on the other hand, was even more unique.

It referred to the skin of living beings, specifically those devoured by the malevolent thoughts of outer heavenly demons. To be designated as 'Ten Thousand Devil Hide,' it required a complete skin of a Soul Transformation cultivator as the primary component.

The remaining parts would be filled with the hides of fourth-tier beings. This aligned perfectly with Wang Yu's expertise, and the 'Six Desires Heavenly Demon Map' successfully refined from these materials possessed extremely powerful cursing abilities.

Named – the Heavenly Demon Soul Seizure Curse!

It could summon true outer heavenly demons to seize control of a target's body and mind. In Wang Yu's opinion, this ability was not particularly remarkable. What was truly astounding was its precise ability to lure heavenly demons.

It would summon exactly one, no more, no less!

Not only could it aid in overcoming the 'Divine Transformation Tribulation,'

but it could also summon a true heavenly demon for Wang Yu to experiment with an idea he had many years ago: whether devouring a heavenly demon with his Demonic Embryo Physique could allow this constitution to further evolve!

After all, the original principle of the Profound Yuan Demonic Embryo was based on imitating the heavenly demon's soul seizure ability. This was why it initially had bloodline restrictions. After advancing to the Innate Demonic Embryo Physique, the secret method was further refined.

Wang Yu was like a miniature heavenly demon fledgling,

possessing various traits similar to their abilities: myriad transformations of heavenly demons, demonic seeds of malevolence, and the power to corrupt minds!

Thus, the idea of devouring a mature heavenly demon naturally arose.

This conjecture—whether it could make the Demonic Embryo Physique further transform—was the true reason Wang Yu came to the Netherworld Ruins. He didn't necessarily need tangible gains.

As long as he could gain insights from the Demonic Heart Venerable's creation of the technique, or derive the subsequent progression path for this secret method, it would suffice.

His plans were interconnected.

Every action of Wang Yu was purposeful.

Returning to the present.

In the desolate ruins, Wang Yu descended his escape light onto a collapsed vermillion pillar. Overlooking his surroundings, his formidable divine sense transformed into dense, invisible tendrils.

With himself at the center, he conducted a meticulous, 'carpet' search of every detail of the area. So precise was his scan that he could clearly discern the grain of every piece of wood.

The situation in the Chaotic Ancient Sea differed from that on land.

Many renowned powerful cultivators here originated as rogue practitioners, subsequently establishing their own factions. The vast, boundless ocean allowed them to hide in its depths, even if they offended someone.

Unlike on land, where cultivation outside spirit cities was difficult, cultivators here were even more audacious than demonic cultivators. Especially the lone wolves who had lost their entire families.

They were all "barefoot, fearing no shoes."

As long as one mastered escape techniques, one could carve out a place for oneself in this maritime cultivation world.

Of course,

overall, the quality of cultivators in the Chaotic Ancient Sea was generally inferior to those in the Chiyuan and Taihu regions. Even the sheer number of cultivators was far less.

Constantly threatened by the sea beast race, it was not an ideal place for sect development. However, it was quite suitable for individual cultivation.

Through his divine sense, Wang Yu quickly located several suspicious areas. He also uncovered an unexpected situation.

Several cultivators, with short hair and clad in simple robes,

were solemnly searching for something within the ruins. This style was known as 'Wanderers,' and they were regarded as a mysterious group that, after the decline of Buddhism, still pursued similar spiritual beliefs.

Almost all of them originated from the Ancient Sect of Heavenly Sea. This was also why this sect was considered the successor to Buddhism. Not only their cultivation methods but even their overall style resembled historical Buddhist records.

However, over time, it had evolved to form a culture unique to the Ice Hell Realm.

Coincidentally,

after Wang Yu finished exploring the Netherworld Ruins, he planned to formally visit the Ancient Sect of Heavenly Sea. He wished to perfect his body refining path; being unable to advance was more unbearable than death itself for someone who was constantly progressing.

The more time wasted, the more life squandered.

Therefore, his primary objective for this journey was to perfect his body refining techniques. Noticing the Wanderers from the Ancient Sect of Heavenly Sea present, Wang Yu chose not to reveal himself or make contact.

Instead, he proceeded to examine the anomaly he had just discovered.

This location was a collapsed underground space north of the ruins. It was almost entirely buried by rubble and dust. Wang Yu, using an exquisitely refined method of demonic energy control,

forcibly expanded the space and cleared the ruins with black ice. Immediately, numerous fractured array patterns came into view. Wang Yu’s gaze went straight to the very center.

A broken stone tablet remained there.

The inscription was already illegible, but faint patterns persisted. As his demonic energy solidified to retrace the lines and make them clear again, through fragmented records,

he could confirm that this was where Nine Evils had obtained the Demonic Embryo Secret Method. This method was the core inheritance of the Demonic Heart Sect, but there was no record whatsoever of the Demonic Heart Venerable himself.

Seeing this, Wang Yu wasn't disappointed.

He then moved to explore the second suspicious location. He examined one place after another, experiencing repeated disappointments, until he reached the final suspicious spot.

Coincidentally, several Wanderers from the Ancient Sect of Heavenly Sea

were also lingering there, their objective seemingly some item within the ruins. Wang Yu pondered for a moment upon seeing this, then took the initiative to speak.

“My young friends, are you searching for something in particular?”

Calling others 'young friends' for the first time, Wang Yu had clearly completed his transformation from an insignificant figure to a powerful grandee. He adapted to his new identity with incredible speed.
