He was not entirely at ease with Wang Yu. Fourth rank cultivation pill materials were extremely hard to come by, so he naturally had to stay close at every step and dared not leave even for a moment.

However, since Wang Yu was the one who made the request first, it was inconvenient for him to insist on entering the alchemy chamber to supervise together. If the alchemy process were disturbed, the loss would ultimately be his own.

Fortunately, it was only a few steps away, all under the surveillance of divine sense.

He believed Wang Yu would not dare play any tricks.

“Then begin.”

“Gladly.”

Seeing Heavenly Frost Demon Lord sit down at the entrance of the alchemy chamber with his back turned, Wang Yu sealed the doors tightly. Among the materials required for the Taiyin Demon Essence Pill, the hardest part to deal with was the demonic qi.

The demonic qi provided by Heavenly Frost was condensed and wrapped inside a piece of cold stone. It was clearly different in nature from the Demonic Star Meteor Crystal taken from the sect blood pool.

During the alchemy process, Wang Yu needed to prevent the demonic qi from affecting him. This could be achieved through the methods of human pill refinement.

Golden Core powder was supreme grade even among supreme grade materials for human pill techniques. Many secret pill dao methods and techniques could be cleverly accomplished by relying on Golden Core materials.

Ten full years were spent seated on the Celestial Enlightenment Dao Platform.

During this period, his cultivation barely advanced at all. It was a form of tradeoff, exchanged for his current unstoppable alchemy skills.

The pill formula was exactly the same as the Guanghan Pill he had refined before.

Now that he comprehended it again, everything went smoothly.

Two months later, Wang Yu officially opened the cauldron. When the fourth rank Ice Chi Pill Flame was reignited, the surging alternation of extreme cold and heat could even be sensed by Heavenly Frost Demon Lord outside the chamber.

He could not help murmuring softly.

“It has begun. Let this lord see what you are capable of.”

His Nascent Soul divine sense enveloped the entire alchemy chamber, including the underground area, to prevent Wang Yu from fleeing if the refinement failed.

However, he did not dare probe directly inside, for fear of interfering with the alchemy.

Half a month later.

Refining ice attribute spirit pills had become even more effortless for Wang Yu. With the enhancement of the Cold Chi Alchemy, the pill efficacy was fully activated, exceeding the original version by fifty percent.

When he peered into the cauldron to observe the interior, Wang Yu’s eyes lit up. Nine pills signified perfection. Two were high grade, seven were mid grade.

This quality was something only a fourth rank high grade alchemist could achieve. As the thought crossed his mind, Wang Yu transformed his divine sense into threads and infiltrated the cauldron, secretly sweeping away the two high grade Taiyin Demon Essence Pills.

He immediately sealed them using the Ice Coffin Sealing Art and hid them deep within his storage ring. If he were to form a Nascent Soul, he would also need high quality cultivation pills to assist him.

He had suffered plenty during the Core Formation stage due to the lack of cultivation pills. Accumulating some resources in advance would make his future cultivation path much smoother.

Such an opportunity was rare. If he did not take advantage of it, he would hardly deserve to call himself a demonic cultivator.

At the instant he swept away the high grade spirit pills, Wang Yu suddenly lifted the cauldron lid. A pillar of spiritual light shot into the sky, stirring the winds and clouds. At the same time, he secretly poured some ashes into the bottom of the furnace.

The next moment, Heavenly Frost Demon Lord burst through the door.

He stared in delight at the spirit pills floating within the pillar of light and quickly counted them.

“Seven. Hahahaha.

“The Seventh Elder’s alchemy skills are truly godlike, far better than those useless fools in the Alchemy Hall. You were only slightly short of gathering nine for perfection. Your future is boundless.”

With just a single glance, he ruled out the possibility that Wang Yu had hidden any pills. There were only seven pills formed. How could any be concealed.

He also had not forgotten that Wang Yu was only at late Core Formation.

Considering the circumstances, this result already exceeded his expectations by a wide margin.

If not for the fact that the orders with the Alchemy Hall grandmasters were scheduled a hundred years in advance, and the remaining ones were all fourth rank low grade alchemists with terrifyingly high failure rates, he would not have turned to Wang Yu.

Now, it seemed this decision was not only correct but worthy of celebration.

Wang Yu feigned exhaustion and said.

“I have lived up to your trust.”

“You have done very well. In the future, you may interact more with the four clans under my command. If you encounter any difficulties, feel free to bring them up. As the Seventh Elder of the Elders Council, you should have some people at your disposal.”

Wang Yu declined politely.

“That will not be necessary. If the Demon Lord requires pill refinement, you may call on me at any time. I consider myself a member of Cold Blood Peak, and there are many matters in which I must rely on the Demon Lord.”

“That is reasonable.”

This time, Heavenly Frost Demon Lord did not grow angry. People with talent and usefulness who could bring benefits were often granted a much higher tolerance.

As long as Wang Yu did not refuse alchemy requests, his neutral position was firmly secured.

“This is a scroll of ten thousand year snow silkworm silk. It is still slightly insufficient for refining a magic robe. I also have several pieces of fourth rank Bone Demon bone armor. If you want them, I will give them to you together today.”

“Then I will gratefully accept.”

After taking everything, Wang Yu knew this bone armor was not truly a fourth rank artifact material, but rather a derivative spirit item. Still, for a Core Formation cultivator, it was an extremely rare treasure.

It could be refined into a Yellow Springs Earth Resentment Puppet to enhance the strength of its body.

“Oh right, may I borrow this pill cauldron for one more use. Such an excellent item makes my hands itch once I start using it.”

“Very well. I will have someone come collect it in three months.”

“Many thanks, Demon Lord.”

“No problem.”

With seven newly acquired cultivation spirit pills suitable for his use, Heavenly Frost Demon Lord also wanted to return and enter seclusion. This batch alone was enough for him to remain in seclusion for thirty to fifty years.

After emerging, his cultivation would surely increase greatly.

Thus he did not wish to waste time on trivial matters. After exchanging a few polite words, with everything implying future cooperation, he finalized the intention and only then left at ease.

Wang Yu then made another trip to Father Yu’s cave abode.

He brought along the ten thousand year Snow Silkworm Silk, as well as one million spirit stones. The cost of repairing the Robe Three Feet Snow would certainly have to be paid out of his own pocket.

He deliberately had the Blood Eyed Demonic Flood Dragon handle the matter, to prevent the items from being embezzled. Based on his experience, such precautions were necessary.

He did not know what the situation was like at Taihu.

But in Crimson Kite, if one revealed wealth exceeding one’s own cultivation realm and then sought help from others, it was no different from delivering oneself as a fat lamb. Back when he refined the Ghost-Weeping Flute, he encountered a Core Formation artifact refiner named Lei Shu.

He used words to intimidate the other party, and only then avoided further trouble.

After Three Feet Snow was repaired, it would at least reach mid fourth rank. Its enhancement for Yin Ice attribute cultivators would reach the maximum. If Wang Yu handled it personally, he absolutely would not be able to keep it safe.

By the time he returned to his own cave mansion, the first light of dawn was already faintly visible.

He immediately activated the formations and continued secluded pill refinement.

This time, it was the Nascent Soul Advancement Pill.

The main ingredient Nine Curves Spirit Ginseng, along with the supporting auxiliary spirit medicines, had been obtained years ago when he participated in the Tianbao City auction and killed the young master of the Yin Yang Sect to seize his treasures.

That had already been many years ago.

The Nascent Soul Advancement Pill formula had also been fully comprehended at accelerated speed on the Celestial Enlightenment Dao Platform. Refining it earlier meant that when it was needed, there would be no delay. With his Heavenly grade spiritual root aptitude, even a single Nascent Soul Advancement Pill would be effective.

There was no need to pursue high grade Core Formation spirit items like during the Core Formation stage. Perhaps this could be considered a form of growth.

However, if better options were available, there was no reason to settle for inferior ones.

Without the special Ice path spirit pill bonus from the Cold Chi Alchemy Art, Wang Yu was returned to his original state. This round of pill refinement was rather ordinary.

Four pills were formed. Three were mid grade, and one was high grade.

Four realm breakthrough spirit pills caused Wang Yu some slight surprise.

This differed from what he had previously understood, but since they were not supreme grade spirit pills, he only thought about it briefly and then let it pass as a minor matter.

At most, it was merely the upper echelon deceiving and sealing information from the lower levels. The information Wang Yu now possessed conflicting with what he knew in his weaker days was actually quite normal.

He had already broken through this layer of informational blockade. Thinking too much about it was pointless.

With so many Nascent Soul Advancement Pills, he needed to consider how to use them to maximize benefits. For now, he would keep them.

Because he deliberately concealed the pill formation phenomena this time, it did not attract any major attention. The usage time of the supreme grade pill cauldron still had one month remaining.

He needed to seize the time to refine the Heavenly Demons into pills.

Inside the alchemy chamber.

Regarding how to process the five formless Heavenly Demons, he already had a preliminary idea. The ancient method of Demon Refining Art would play the most crucial role.

Its principle was to use a living demon beast, apply secret techniques directly to its demon core, and create a reverse devouring force that swallowed the demon beast’s blood, flesh, bones, demonic power, and everything it possessed.

All of it would be absorbed into the demon core, forming a lump of flesh.

At that point, fierce fire would be used to refine it, removing impurities, ultimately producing a blood flesh spirit pill that provided enormous nourishment when consumed. The bloodiness of the Demon Refining Art revealed ancient characteristics everywhere.

That was primitive and savage blood soaked slaughter.

What Wang Yu valued was its property of devouring everything. If a Heavenly Demon were placed inside a demon beast, could it also be absorbed into the demon core through the Demon Refining Art?

Once this step succeeded,

it would force the Heavenly Demon to transform from formless to tangible. In that case, there would only be more methods available for refinement. When it reached the stage of tempering and extraction, that would be Wang Yu’s domain to fully display his abilities.

The Demon Refining Art had not been verified and could not confirm whether it could restrain Heavenly Demons, beings from beyond this world.

However, sealing secret techniques had been verified.

What he needed to do now was to find a way to combine the Ice Coffin Sealing Secret Technique with the Demon Refining Art. At this step, Wang Yu chose to use formations as assistance.

His use of blank formation flags was second nature.

By engraving the sealing secret technique onto them, they could be extended into the alchemy process at critical moments. This was not a true formation, but rather a delayed activation technique.

The difficulty was not high.

After all the preparations were complete, Wang Yu spent spirit stones to have more than twenty Foundation Establishment demonic beasts captured alive at the border of Night Jewel Prefecture, in the northern section of the Severed Boundary Mountain Range, and delivered to him.

The bodies of demonic beasts were merely vessels, so the requirements for cultivation level were not high.

If he were to use third rank demonic beasts, he truly could not afford it. They had to be alive, and once a demonic beast reached the third rank, it was entirely different, with its strength surging dramatically.

Unless he personally went out to capture them. Unfortunately, at his current stage he could not leave the sect, so he could only spend spirit stones to purchase them.

Half a month later.

Inside the sealed alchemy chamber, the shrill cries of demonic beasts rose and fell without end. The thick, rancid stench was almost suffocating. After Wang Yu put on the Earth Net Ghost Mask, he felt much more at ease. 𝙛𝒓𝓮𝙚𝔀𝒆𝒃𝓷𝒐𝓿𝙚𝓵.𝙘𝒐𝒎

Before refining the Heavenly Demons, he still needed to run several experiments with the Demon Refining Art.

Although this was his first attempt, Wang Yu’s techniques were incomparably smooth. Blue black mana turned into fine threads, probing into the body of a black crow demonic beast from all directions.

The instant they touched the demon core, dense demon refining incantations rapidly formed. In the blink of an eye, it was as if a black hole appeared inside the black crow demonic beast, causing it to collapse inward.

In an extremely bizarre posture, it was compressed into a flesh ball the size of half a palm. Throughout the entire process, not a single drop of blood or a single feather fell.

There was not even any resistance. It simply succeeded.

Wang Yu’s eyelids twitched. He felt that this Demon Refining Art was truly sinister. This was only the third rank alchemy path chapter, and it was obvious that much of its content had not been fully supplemented.

Not to mention the even more incomplete and powerful artifact path chapter, talisman path chapter, formation path chapter. No matter how one looked at it, it was ominous.

A mere second rank demon refining flesh pill emerged from within the embrace of the Ice Chi Pill Flame in less than half an hour. All the blood flesh and scattered feathers had already disappeared.

The entire pill was covered in black feather patterns. The pill fragrance leaned more toward the smell of a pot of cooked meat, yet it was an extraordinarily enticing aroma. Just a whiff made one’s mouth water.

Wang Yu attempted to swallow it and refine it.

Only then did he discover what was truly extraordinary about flesh pills refined through the demon refining art. What it refined was the very foundation of the demonic beast.

It could be called bloodline, it could be called origin, or even, to a certain extent, its true form.

After swallowing and refining the pill, he felt his body become slightly lighter.

Although the change was very faint, it undeniably existed.

“It should be because the gap in cultivation is too large. A flesh pill refined from only a second rank demonic beast has too little effect on me. I need to try more.”

This time, he selected a demonic beast with a relatively good bloodline as the test subject.

Again, after half an hour.

He swallowed and refined the pill.

This time, Wang Yu was even more pleasantly surprised.

“Scaled Demon Art, Rain Shot Technique. This is an Demon Race bone art?”

In theory, demon race treasure bones could only be condensed by those with powerful bloodlines, to be passed down for bloodline descendants to learn.

The scaled demon Wang Yu used for his experiment was decent, but it had not reached the minimum requirement to produce treasure bones. Back then, the Hidden Dragon Treasure Bone he obtained was extremely special.

The Rain Shot Technique was merely a second rank low grade technique, utterly trash.

Yet he had actually glimpsed its inheritance from the demon refining flesh pill.

The significance of this was far greater than a temporary enhancement of the physical body. Wang Yu believed that if he refined even more powerful demonic races, his physical body should be able to gain even greater benefits.

Demon Refining Art. Terrifying beyond measure.

It might even become the greatest opportunity in his hands. Its potential still awaited further exploration, and there was no need to rush.

The urgent matter at hand was still dealing with the Heavenly Demon.

He ran several more experiments, and combined sealing formation flags with the Demon Refining Art. After confirming there were no issues,

Wang Yu’s black hand finally reached toward the main target.

He took out the empty ice coffin. It appeared to contain nothing at all, but through the Mysterious Origin Demonic Embryo, he could sense what was inside.

That impatient urge to devour became the basis by which Wang Yu judged whether the Heavenly Demon had broken free of its seal.

He reached out and drew over a demonic beast, shrank the ice coffin and placed it inside its body, then cast the Demon Refining Art once more. Midway through the transformation of the demon core, with a thought, he shattered the seal on the ice coffin.

The eyes of this tiger demon instantly turned pitch black.

Dense demonic intent turned into black fog, as if demonic claws were about to reach toward Wang Yu, but they were sucked into the collapsing demon core. The sealing formation flags radiated intense spiritual light.

Incantations spread out, completely locking down the newly formed flesh pill.

Pale white flames rose up.

Using the Blood Pill Art method, Wang Yu used blood as a catalyst to separate the portion belonging to the tiger demon from the flesh pill, quickly forming a blood pill beside it.

Within the hollow spherical cage formed by the sealing incantations,

A mass of pitch black blood flesh was undergoing transformation. The corners of Wang Yu’s mouth lifted as he suddenly increased the power of the Ice Chi Pill Flame. Invisibly, it was as if shrill screams echoed beside his ears.

It was fire refined for a full ten days.

A Heavenly Demon Pill, black gray throughout, was finally produced. Because of the special refining method, there was only a single pill, yet it made Wang Yu extremely pleased.

After testing the pill, he swallowed it and refined it.

The Mysterious Origin Demonic Embryo instantly trembled.

“This is…”
