Wasted Spiritual Root to Embark on Demonic Cultivation

Chapter 230

All conditions, all prerequisites—before the Idle Slot, they were nothing but trivial requirements.

Back then, the reason he liked to practice incomplete techniques and study extremely difficult secret arts was not out of preference. Easy techniques were not necessarily weak, but difficult ones were always strong enough, unique enough.

With the help of the Idle Slot, he had taken a shortcut on his cultivation path.

[Idle Slot 6: Yellow Springs Great Hand Seal (Third-Rank Divine Ability)]

“Yellow Springs Great Hand Seal (0/100): 12 practices per day, perfection in a hundred years.”

“One feedback per hour…”

Wang Yu looked at the note of a hundred years and was unsurprised. He was only at the Foundation Establishment stage, and the Idle Slot made its judgment based on him as the model.

This meant that, as he was now, it would take a hundred years of sleepless cultivation to achieve perfection in this divine ability. Yet, this was not unchangeable.

As he grew stronger, the Idle Slot, which used him as its template—would also become stronger. When he condensed his Core Formation, the requirements for these third-rank divine abilities would decrease considerably.

For example, when he placed a first-rank lower-grade spell into the slot, it might take only a dozen days to reach perfection. That was the benefit of higher realms.
The more techniques he learned, the greater his acquired comprehension became. This was a kind of enlightenment formed through experience, insight, and effort—a towering understanding.

Aside from lacking the instinct of sudden inspiration and the difference of innate comprehension, there was actually not much disparity.

He remembered that every time a spell, technique, secret art or even a strange art or bone art reached perfection, runes would sink into his Qi Sea within his Dantian.

That might be some proof of his increasing comprehension.

Whether there were more benefits, he had not yet realized or perhaps, not yet sensed them.

At the moment, Wang Yu quietly cultivated, waiting for an hour to pass. The first wave of feedback finally arrived.

The Yellow Springs Energy returned by the Idle Slot was clearly refined. Although the quantity was small, it gave Wang Yu a sense of resonance with his essence.

Cold, gloomy… like a Yin Nether Demonic Flood Dragon. No, even stronger than that. The Yellow Springs Power felt like a freezing force capable of sealing everything, containing an extremely high-level Yin attribute.

It perfectly matched his current cultivation path: Yin and Ice.

He even felt that the cultivation method of the Yellow Springs Great Hand Seal might be more suitable for him.

The power that flowed back from the Yellow Springs occupied a portion of the lake of his True Essence, staining his originally blue-black True Essence into a murky yellow.

Although only a part, he clearly felt the quality of his True Essence had improved.

Before long, Wang Yu withdrew from his comprehension and murmured, “Cultivating the Yellow Springs Great Hand Seal actually purifies True Essence…”

Unconsciously, he looked at his hands.

The murky yellow portion of his Yin True Essence automatically flowed into his hands, tempering his muscles, bones, and meridians. It greatly expanded the capacity of his hand meridians and left behind runes symbolizing the Yellow Springs on the inner walls.

This was the process of cultivating the Yellow Springs Great Hand Seal.

When his hands were completely covered in the Yellow Springs runes, it would mean the divine ability had reached minor completion. When it sank completely into his muscles and bones, it would be at major completion.

However, within his Qi Sea, the murky yellow True Essence that had been consumed did not recover. The True Essence regenerated by his cultivation method was still the original cold Yin Essence.

He roughly understood the essence of this divine ability.

“It really feels suitable as a life-bound divine ability… but let me observe a bit longer.”

The Yellow Springs Great Hand Seal possessed the properties of Yellow Springs Water, capable of washing away all things. Simply put, it had a powerful spell-breaking effect.

A single slap could scatter an opponent’s spell or divine ability back into its most primitive spiritual energy. Against a magic treasure, it could sever or suppress the user’s connection with it.

At higher mastery, it could even wash down the rank of an enemy’s treasure.

It enjoyed great fame in the Crimson Kite Demonic Domain and Taihu Domain—for good reason. Those who had experienced it all agreed it was infuriating; this thing could bankrupt you.

Only those with profound inheritances could resist it.

Including the Lesser Asura Killing Fist, this was the second divine ability Wang Yu had mastered.

Neither came from the Blood Reversal Sect’s inheritance, which was rather surprising.

Once he cultivated these two divine abilities to the minor completion realm, they could replace his Mysterious Yin Hand and Ice Wheel Technique, becoming his new formidable trump cards.

In the cultivation world, once a trump card was revealed, one had best quickly rise a whole level afterward—because intelligence was a crucial factor.

After finishing his comprehension, Wang Yu told no one. He went to the second level of the cultivation chamber to study the Killing Intent Stone Slate.

As days passed, Han Jia frequently sent people to deliver the materials he ordered.

As a result, this cultivation chamber expanded once again.

Following the Killing Intent Chamber and Insect Room, he added a Corpse Refining Chamber as the third section.

Since he wanted to do it, he would do it perfectly. Wang Yu constructed two Blood Pools according to the highest standards of the Lunar Yin Fiend Corpse Refining Art—one pure Yin and one pure Yang—laid out according to the Taiji dual-element pattern.

They were specifically for nurturing Demonic Corpses and Thunder Corpses. Together with the Lunar Yin Fiend Corpse, possessing all three rare types of zombies, even True Disciples from Heavenly Corpse Peak would drool at the sight.

The construction of the Blood Pools also subtly followed the principles of Feng Shui Strange Arts.

Do not be fooled by its ordinary name—it contained profound mysteries.

It was a technique for observing the world’s spiritual veins, and very few cultivators truly understood it.

It was closely related to formations.

Formation Masters were divided into three paths: Heaven, Earth, and Human. Just as alchemy had its division between water and fire refinement, the Heavenly Formation Master commanded the timing of the heavens, understood the constellations, could shift stars and constellations, and draw upon the power of the celestial bodies.

The Earth Formation Master commanded the earth veins, pursued myriad spirits, could move mountains and fill seas, and draw upon the power of rivers, mountains, and oceans.

The Human Formation Master was the most ordinary type. The formation flags and disks used in modern times, those simple models, were all founded by them, and their potential for advancement was enormous.

These three paths were not ranked in order, nor were they exclusive. One could simultaneously cultivate as a “Heaven, Earth, and Human Formation Master.”

The art of geomancy was the ultimate skill created by Earth Formation Masters and could be applied to almost anything.

The formation Wang Yu arranged, the Yin-Yang Corpse Refining Formation, was merely a rote imitation. He understood neither its principles nor its structure or logic.

Its effect was rather ordinary, merely increasing the speed of corpse refinement.

Although Wang Yu was interested in formations, his fascination with geomancy was even greater. For a cultivator, this craft provided unparalleled auxiliary benefits.

If not for the limited number of Idle Slots available, he might have studied it as well, perhaps gaining an opportunity in the future.

Wang Yu remembered that Gu Zhengshun’s mentor, “Master Di Yinzi,” possessed the inheritance of an Earth Formation Master. He surely mastered an entire system of geomancy techniques, and even the various Heaven-and-Earth arrays recorded within would be an invaluable fortune.

It took Wang Yu nearly half a year to fully arrange the corpse refinements.

Both the Lunar Yin Fiend Corpse and the Corpse-Nurturing Coffin were placed here for recovery. The Fiend Corpse was already close to advancing to the middle stage of the third rank, but Wang Yu dared not let it proceed.

If it backfired, it would spell disaster.

After he nearly exhausted his supply of Purple Thunder Molten Gold Liquid and accumulated over 1,400 drops of essence blood in his Dragon Spine, a new body-refining treasure was prepared.

At the cost of 980,000 spirit stones, Han Jia personally delivered a third-rank spiritual material, the Myriad Spirit Venom Marrow. It was the size of a basketball and weighed nearly five tons.

This item was extremely lethal, a metal-type toxin that could activate the flesh. In simple terms, it enhanced vitality, resilience, and immunity.

It could greatly strengthen the body’s recovery ability, granting immunity to diseases and ordinary poisons, but one had to endure the erosion of the Myriad Spirit Venom Marrow.

It was practically tailor-made for Wang Yu. With his Immaculate Jade Toad, if he truly could not withstand the poison, he could let it take a single breath of the toxin and surely survive.

This also happened to satisfy the toad’s need for toxins.

Two uses from one item, maximizing its value.

Thus, Wang Yu slightly shifted his focus. He nearly abandoned his time spent on alchemy and spell techniques, relying solely on his Idle Slots for improvement.

The time devoted to cultivation and body refinement increased even further.

In the cultivation chamber, Wang Yu sat cross-legged before the Myriad Spirit Venom Marrow. Using his palm as a blade, he sliced off a fingernail-sized piece and held it in his hand.

The Immaculate Jade Toad lay on his leg, watching intently. Its eyes fixed on Wang Yu’s hand as it quickly turned black. The terrifying toxin spread rapidly through his meridians.

For the toad’s convenience, Wang Yu was nearly nude, covered only by a white cloth. As black veins spread across his entire body, he began to tremble visibly. His blood and the toxin boiled together, and drops of purple-black blood seeped from his pores.

As the blood slid down his skin, it left behind trails of toxic marks.

The Immaculate Jade Toad immediately opened its mouth and sucked. It eagerly absorbed the poisonous blood, its jade-white body darkening for an instant before returning to normal.

It followed the growth cycle of an insect completely. Each time its size increased, it had to cocoon itself, liquefying its body and metamorphosing anew.

This was perhaps why it was regarded as a miraculous insect.

The toxin invasion lasted for half a month. When Wang Yu was on the brink of collapse, the Immaculate Jade Toad bit his wrist, swallowing all the remaining toxin. The small jade toad instantly turned black and then cocooned itself as Wang Yu regained consciousness.

Relief flooded his heart.

“Fortunately, my estimation was right. This was exactly the toad’s limit. This piece of Myriad Spirit Venom Marrow should be enough for the Immaculate Jade Toad to shed its juvenile form and reach maturity.”

Freed from the poison’s influence, Wang Yu’s body recovered swiftly. It was as though he had been reforged, with all his physical indicators soaring.

The number of essence blood drops within his Dragon Spine skyrocketed to over 2,500, increasing by more than 1,100 in one go. The result was terrifyingly effective.

“This first session went remarkably well. Once the body fully recovers, I should only be able to perform this once a year. Next time, the dosage must be larger—perhaps a fist-sized piece.”

Muttering to himself, Wang Yu made several mental calculations.

He estimated that the remaining Myriad Spirit Venom Marrow could be used three or four more times before depletion. The improvements it brought were truly astonishing and would save him a great deal of time.

The expenditure of nearly one million spirit stones was worth it, enough to raise his blood essence count to around seven to eight thousand drops—just one step away from the peak of the second rank.

Meanwhile, Han Jia’s commission continued. He still needed a Core Formation spiritual material specialized for body refinement, which he intended to trade for another superior-grade one.

Truly perfect.
