Chapter 229 Abundant Harvest, Inheritance of a Heavenly Grade Spirit Array Master!
"Tsk tsk..."

"It has to be the Martial Ancestor. If it were my brother Yan, he'd probably hesitate a bit..."

Lu Yu clicked his tongue in amazement, then turned his gaze to the three options.

Although the White Dragon Spirit Pearl is good, the remnant of the White Dragon Supreme within it is actually not very useful. The remnant is not a remnant soul after all; it is merely a shadow formed from a mixture of obsession and spiritual power, and there is almost no possibility of resurrection.

In Lu Yu's view, this state was probably similar to that of the Pure Lotus Demon Saint in the Pure Lotus Demon Flame Fragment in his hand, and the Heavenly Emperor in the ancient Heavenly Palace who sacrificed himself to suppress the demon.

These ancient powerful beings have endured countless years, and their original souls have long since dissipated, remaining only through a lingering obsession.

To revive them is as difficult as reviving a single thought from the river of time.

Even the Flame Emperor, who had already reached the Saint-grade Alchemy Grandmaster level, was helpless. Perhaps only the legendary transcendence of the Saint-grade realm offers a sliver of hope.

As for the inheritance of the White Dragon Supreme, Lu Yu believed it was nothing more than the Dragon Ascension Technique, which he had already mastered, so there was no need to choose it again.

As for the Nine-Turn Ice-Clearing Pill, the main ingredient is already in hand, and the auxiliary materials are collected with the help of the Pill Tower, so it is entirely possible to refine it on one's own. It is not worth wasting this opportunity.

It is already obvious how to choose.

Lu Yu made his choice immediately after a moment's thought.

The next moment, purple light flowed in his palm, and an ancient purple jade slip quietly appeared. He immersed his mind in it and was immediately drawn to the vast array of spiritual array inheritance within:

"Level 1 Spirit Array: Flame Spirit Array; Level 2 Spirit Array: Lightning-Attracting Array; Level 3 Spirit Arrays: Flowing Fire Binding Spirit Array, Mystic Ice Mirror Array, Wooden Dragon Entangling Silk Array; Level 4 Spirit Arrays: Rock-Suppressing Mountain Array, Hundred Swords Slaying the Sky Array; Level 5 Spirit Array: Thousand Illusions Sword Qi Array; Level 5 Combined Spirit Array: Departing Fire Sword Qi Array."

Lu Yu's gaze swept past these basic spirit arrays, finally settling on the five supreme-level spirit array inheritances:

The "Ten Thousand Fires Burning Heaven Sword Formation" represents a person of high moral character.
High-grade Earth-level "Great Annihilation Thunder Sound Sword Formation";
The intermediate-grade Earth-level "Nine-Turn Mystic Turtle Sea-Suppressing Array" and "Zhou Tian Star-Locking Spirit Array";
And finally, the "Nine Heavens Thunder Emperor Sword Formation" gifted by Qing Yanjing.

To Lu Yu's surprise, this was actually a powerful spirit array of the high-grade Heaven level. If it were to be used at full power, its strength would be comparable to that of a peak Ninth Grade Supreme expert!
What surprised Lu Yu even more was that the jade slip also contained a matching soul cultivation technique—the Thunder Emperor's Book.

He carefully scanned the soul technique called Thunder Emperor's Book with his spiritual power. After a moment, his eyes narrowed slightly, and he stroked his chin, saying, "Thunder Emperor... a ninth-grade supreme being, a high-level Heaven-grade spirit array master. This is a soul technique that can be cultivated to the Great Perfection of the Heaven Realm..."

"In terms of grade, it should be considered a high-level Heaven-rank soul cultivation technique..."

Lu Yu muttered to himself, then pondered for a moment before deciding to switch to cultivating this technique.

At his level, Earth-rank cultivation techniques are no longer very useful, and there's no need to waste time cultivating three soul cultivation techniques simultaneously.

He sat cross-legged, carefully reviewed the key points of the technique, and after confirming that there were no errors, he immediately formed hand seals and began to cultivate this soul technique created by a ninth-grade supreme expert.

As he circulated his cultivation technique, a purple lightning pattern gradually lit up between his eyebrows, and strange phenomena appeared in his mind—wisps of fine purple lightning shuttled like dragons, constantly refining and purifying the originally formless soul power.

Upon closer inspection, one could see that the flickering lightning was slowly altering the form of his soul's essence. The originally erratic soul fire, forged by the power of lightning, gradually condensed into shimmering, purple threads.

These silk threads intertwine, vaguely forming a seated phantom, identical to Lu Yu's true form.

"boom--"

A thunderclap, perceptible only to the soul, echoed deep within Lu Yu's mind. His aura surged dramatically, and his soul realm advanced once more in a short period.

He slowly opened his eyes, lightning flashing in his pupils: "Peak of the early stage of the Heavenly Realm... After switching to cultivating the Thunder Emperor's Book, the quality of my soul power has indeed reached a new level."

Just then, a gentle yet clear voice came from outside the quiet room:
"Sect Master Lu, President Xuan Kongzi requests your presence."

Lu Yu concealed his aura, slowly stood up, and replied, "Thank you for leading the way."

……

Not long after, at the top of the Pill Tower, in a simple and elegant hall, the three Pill Tower giants, Xuan Kongzi, Tian Leizi, and Xuan Yi, were already waiting.

Upon seeing Lu Yu arrive, Xuan Kongzi was the first to stand up and greet him.

“Pavilion Master Lu,” Xuan Kongzi said solemnly, “we have already discussed your previous proposal in the Grand Elder Council of the Little Pill Tower. Now that the Ancestor’s whereabouts are unknown, all major affairs of the Pill Tower are decided by a vote of the ten members of the Grand Elder Council.”

He paused slightly, then continued, "After a vote, the three of us and the other three elders all voted in favor, for a total of six votes. Therefore, the Pill Tower agrees to your request in principle and promises that if the Soul Palace attacks, it will do its best to ask the Ancestor to intervene on behalf of the Spirit Treasure Pavilion."

"In principle?" Lu Yu raised an eyebrow upon hearing this, keenly catching the reservation in the words.

Xuan Kongzi sighed softly and explained, "Please forgive us, Pavilion Master Lu. It's just that our Ancestor travels around all year round, and his whereabouts are unpredictable. We really don't have a sure chance of contacting him in time."

Tian Leizi promptly took out a warm, smooth jade talisman and handed it over: "This is a specially made communication jade talisman. Once we receive news of the Ancestor, we will contact you immediately and do our utmost to make this happen."

Xuan Yi then added, "Even if the Ancestor fails to return in time, the Pill Tower will never stand idly by. At that time, our Pill Tower will personally rush to the aid of the Spirit Treasure Pavilion to fight against the powerful enemy."

With that, she flicked her sleeve, and several jade boxes appeared neatly on the table. She said softly, "These are the medicinal herbs you need, Xiao Lu. Please check if this is enough."

Lu Yu glanced at the jade box, pondered for a moment, and then nodded slightly. Although he hadn't received a clear promise from the Pill Tower Ancestor, with the Little Pill Tower's guarantee and these precious medicinal herbs, the deal was still worthwhile.

He reached out and took the jade talisman, and at the same time, with a flick of his sleeve, he collected all the medicinal herbs.

Upon seeing this, the three of them breathed a sigh of relief.

……

Not long after, in a quiet courtyard in the inner region of Saint Dan City.

Lu Yu held his breath and focused his mind, the Azure Phoenix Cauldron hovering steadily in front of him. He flicked his finger, and a cluster of deep black flames leaped into the cauldron, causing the temperature of the entire courtyard to rise sharply.

Dozens of precious medicinal herbs were added one by one under the precise control of his Heavenly Realm Soul Power, and quickly transformed into crystal-clear medicinal liquid or condensed into pure medicinal powder in the flames.

With his current Heavenly Realm soul power, plus the assistance of Dou Sheng-level flames, refining an eighth-grade pill, even at the peak of the eighth grade, would not take much time.

Xiao Yan stood quietly to the side, his gaze intense. He had watched as Lu Yu used his soul power to simultaneously control fifty-six different medicinal herbs, extracting their essence in an instant. Such skill was simply divine.

Three days later,

As the final hand seal was formed, the sky above the courtyard suddenly changed, with nine-colored lightning churning and condensing in the clouds, radiating a terrifying pressure from heaven and earth.

"Nine-Colored Pill Lightning! It's a peak-grade eighth-rank pill!"

"It's been so many years since the Nine-Colored Thunder God has appeared in the world!"

An uproar erupted in Saint Dan City, with countless shocked gazes directed towards the courtyard.

"Congeal!"

With a clear shout, Lu Yu caused the cauldron to shine brightly, and a stream of icy blue light shot into the sky. He raised his hand and grasped, and the Nine-Turn Ice Purity Pill landed steadily in his palm.

The moment the pill was in hand, nine-colored lightning bolts crashed down from the sky!

Nine bolts of lightning, each a different color, intertwined to form a web of destruction, enveloping the entire courtyard. The blinding light made it nearly impossible for onlookers in the distance to open their eyes.

Faced with this earth-shattering tribulation, Lu Yu simply flicked his sleeve and calmly called out, "Xiao You."

A faint light shot out in response, transforming into an inconspicuous black vortex in the air. The vortex, though seemingly small, resembled an invisible giant maw.

The raging nine-colored lightning was absorbed into it like rivers flowing into the sea, without even a ripple.

"What...what kind of method is this?!" "The Nine-Colored Pill Lightning...it was just taken away like that?"

"That's the Nine-Colored Pill Lightning that even peak Dou Zun experts have to avoid!"

"Could it be that this Pavilion Master Lu has already reached the Saint Realm?"

The entire Holy Pill City was in an uproar. Countless alchemists took to the air, trying to see what was happening in the courtyard, but they were blocked by an invisible spiritual array and could not see the truth.

Inside the courtyard, Lu Yu remained oblivious to the commotion in the city. He carefully examined the Nine-Turn Ice Purification Pill in his hand, and only after confirming its perfect quality did he put it into the jade bottle.

Xiao Yan stood aside, having witnessed everything that had just happened. Suppressing his shock, he stepped forward and asked respectfully, "Brother Lu, what was that just now...?"

"It's just a little trick."

Lu Yu brushed it off lightly, then turned to Xiao Yan, "You brat, instead of studying alchemy under Senior Yao Lao, what brings you here?"

A little trick?

Upon hearing this, Xiao Yan couldn't help but give a wry smile. He looked inward at the three trembling strange flames within his body. If his perception was correct, the faint light just now was clearly formed from an extremely powerful strange flame.

Such power is probably beyond even the master's Bone Spirit Cold Fire.

The group of alchemists watching from outside the courtyard must have sensed the chilling aura of the strange fire, which is why they were so restless.

After all, even if one knows they have no chance with a strange fire of this level, being able to witness it firsthand is a rare opportunity for any alchemist.

"Brother Lu, I've come here because I have a favor to ask of you?"

Upon hearing this, Xiao Yan's expression turned serious, and he immediately spoke.

"Oh? What could it be that you need?"

Upon hearing this, Lu Yu chuckled and said, "Didn't you just break through to the Dou Zong realm? Even your alchemy skills have reached the eighth rank. You're quite the big shot right now..."

Xiao Yan touched his nose somewhat embarrassedly and said, "Brother Lu, I would like to ask if you know where I can find a treasure to repair the origin of the soul? My teacher's soul was severely damaged back then. Although he has now recovered to the peak of the Spirit Realm, he has never been able to recover to the Heaven Realm."

Lu Yu put away the Nine-Turn Ice-Cleansing Pill, sat on the futon, and stroked his chin thoughtfully, "A treasure for restoring soul power? It seems that the amount of Heavenly Soul Nourishing Liquid I used before was still too small, not enough for Senior Yao to recover..."

Back when he was still in Wutan City, he studied alchemy under the old master for a period of time. In return, he gave the old master a spiritual item that could be used to repair the soul and resist the burning of the divine soul fire.

That is the Heavenly Soul Nourishing Elixir, one of the spiritual items used by powerful figures in the Great Thousand Worlds to break through the Divine Soul Difficulty.

Treasures that can restore the origin of the soul are extremely precious. This Heavenly Soul Nourishing Liquid is already top-tier below supreme spiritual objects, and it is the highest-level soul treasure I obtained in the early stages of the simulation.

At the time, he speculated that after taking the medicine, the old man would at least recover to the Spirit Realm. Now it seems that he underestimated him; the peak of the Spirit Realm.

Lu Yu pondered for a moment, then said, "Brother Yan, I have a few ideas. As far as I know, there are two kinds of rare items in this world that have the miraculous effect of repairing the origin of the soul."

"Which two?" Xiao Yan hurriedly asked.

"Soul Infant Fruit and Spirit Dragon Heavenly Mushroom".

Lu Yu slowly said, "If you obtain either one, you can help Senior Yao recover to the Heavenly Realm. Unfortunately, these two rare items are even rarer than the Strange Fire, and are something you can only hope to encounter but not seek out."

Upon hearing this, Xiao Yan immediately became anxious: "Then what should we do?"

Lu Yu remained calm. He didn't know the whereabouts of the Spirit Dragon Heavenly Herb, but he knew perfectly well where the Soul Infant Fruit was. However, this matter couldn't be discussed openly, since there was no such thing as predicting the future on the Dou Qi Continent.

"In that case..."

Xiao Yan looked slightly disappointed. "I'll just send more people to search."

"Actually, there is another way, Brother Yan."

"any solution?"

"Let's go to the Soul Palace."

Lu Yu's lips curled slightly as he continued, "Soul essence is scarce in other places, but the Soul Palace never lacks it..."

He tapped the table lightly with his fingertips, his gaze deep: "As far as I know, the Soul Palace's branch halls contain a considerable amount of purified soul essence. Instead of searching aimlessly, we might as well just take what's readily available."

Xiao Yan was taken aback at first, then his eyes blazed with fervor. This bold suggestion truly stirred his heart.

"This isn't right, Brother Lu..."

"Your Lingbao Pavilion has just encountered the Soul Palace..."

"So it is precisely for revenge."

"But I've heard that the Lord of the Soul Palace is a true Dou Sheng powerhouse, and five of the nine Heavenly Venerables of the Soul Palace have already fallen at your hands. Shouldn't we be a little more cautious...?"

"If we provoke them any further now, the Lord of the Soul Palace might personally come out of seclusion to deal with us..."

“That makes sense. In that case, let’s search for the Soul Infant Fruit and the Spirit Dragon Heavenly Herb first…”

Upon hearing this, Lu Yu immediately nodded.

If I remember correctly, the Soul Infant Fruit is located in the Creation Saint's Ruins in the Beast Domain's Skeleton Mountains, in the same place as the Dragon and Phoenix Origin Fruit.

Among the Heavenly Grade Alchemist inheritance he inherited, there happened to be a prescription called "Dragon and Phoenix Supreme Pill," which required the essence and blood of true dragons and phoenixes as the main ingredient.

Although the quality of the essence blood from the lower plane is slightly inferior, it is enough to perfectly activate the medicinal effects of the Dragon-Phoenix Origin Fruit. If it can be refined into the Dragon-Phoenix Supreme Pill and given to Zi Yan, it will surely help her achieve perfect evolution.

At that time, with the evolved Zi Yan restraining the Soul Palace Master, she and Yan Di could act freely.

As long as I acquire enough soul essence, I have a good chance of breaking through to the middle or even late stages of the Heavenly Realm.

With the addition of the Heavenly Grade Spirit Array inheritance he just obtained, his overall combat power will surely increase rapidly in a short period of time.

Seeing that Brother Lu agreed, Xiao Yan breathed a sigh of relief. He was really afraid that Brother Lu would rush into the Soul Palace and start a massacre without regard for anything else.

It wasn't that he was worried about Brother Lu's strength, but rather that he was worried about the Soul Hall's methods. The Soul Hall's foundation was unfathomable, and there was no need to escalate the conflict further and provoke even stronger members of the Soul Hall to attack.

"It's good that Brother Lu thinks that way."

Xiao Yan's expression softened slightly, and he said seriously, "Then I'll head back to the Starfall Pavilion to gather information?"

Lu Yu nodded slightly and said with a smile, "Go ahead. Remember to keep an eye out for news about ancient ruins. Treasures like the Soul Infant Fruit and the Spirit Dragon Heavenly Mushroom, which are extremely rare, usually appear in those places."

He flicked his finger, and a communication jade talisman floated towards Xiao Yan: "Notify me immediately if there is any news."

After Xiao Yan's figure disappeared outside the courtyard, Lu Yu turned and looked towards the direction of the Beast Domain.

He muttered to himself, "Speaking of which, that seems to be the territory of the Nine Netherworld Python clan, right?"
