While the player is in Battle Through the Heavens, the system is in The Great Ruler.

Chapter 222 Ancestral Crystal Baptism, Peak of the Ninth Revolution!
"Ancestral Symbol Crystal? There's such a thing?"

Lu Yu looked at the simulation results and a look of surprise appeared in his eyes.

As far as he knew, although the world was vast and boundless, rare items that could help one break through to the Heavenly Supreme realm were extremely rare.

After all, the Heavenly Supreme is already among the top tier of people in the Great Thousand World, and is by no means easily attainable.

Countless exceptionally talented individuals have spent their entire lives stuck at the Great Perfection of the Earthly Supreme Realm, unable to ever glimpse the threshold leading to the highest realm.

This requires not only exceptional talent and abundant resources, but also a rare and serendipitous opportunity.

As far as he knew, such an opportunity, apart from the 'Planet Embryo' which gathers the origin of the entire plane, could only be obtained through the baptism of the 'Continental Child' which takes hundreds of years to form after being nurtured by heaven and earth, and could slightly increase the success rate of breaking through to the Heavenly Supreme.

Lu Yu stroked his chin, lost in thought.

In his view, the Embryo of a Plane and the Child of the Continent are essentially the same thing. The former condenses the essence of a plane, while the latter gathers the origin of the continent.

However, the power of the continent is hidden deep within the earth, and only the supreme being can activate it. Moreover, not all continents are qualified to nurture a sufficiently vast power of the continent.

Therefore, the quota for the Son of the Continent is extremely precious even in the Great Thousand Worlds, and can only be conceived by a high-level continent controlled by the best among the Immortal Heavenly Sovereigns.

"Even if this Ancestral Symbol Crystal can't compare to the Embryo of a Plane, its value is probably no less than that of a Baptism of the Son of the Continent. Such an opportunity is not to be missed."

"As for the other options..."

Lu Yu's gaze fell on the options in the inheritance jade slip, and he silently pondered, "Based on the experience of this simulation, the cultivation methods in the inheritance jade slip are most likely to be the Eight Desolate Emperor Flame Technique, the Eight Desolate Emperor Flame Dharma Body Cultivation Method, the Great Sun Flame God View, and the Great Desolate Imprisoning Heaven Finger."

"As for cultivation techniques and Dharma bodies, I already possess the Great Floating Pagoda Technique and the Sword Sun Undying Body, so there's no need to change them. What I lack is a Heaven-Rank Soul Cultivation Technique, and as for the Great Wilderness Imprisoning Heaven Finger..."

He pondered for a moment, then shook his head: "With the support of the Fallen God Sword and the Fusion Spirit Secret Technique, the power of the Great Luo Heavenly Flame Sword is already comparable to a mid-level Heavenly Rank Battle Skill. Once I nurture the spirit of the strange fire, its power will increase even more, enough to support its use until the Battle Saint realm."

"Moreover, there's also the nascent divine power born from the Fallen God Sword..."

"There's no need to exchange for this perfect divine technique for now. As for its advanced peerless divine ability, the Eight Talisman Finger... ten years of simulation is too short, it's still too far away for me..."

"In that case, let's choose it."

With this in mind, Lu Yu made his choice.

The next moment, a dazzling golden light shone in the quiet room, and a crystal about the size of a fist quietly appeared in his palm.

At first glance, this Ancestral Symbol Crystal appears perfectly round, displaying a warm, golden hue. However, upon closer inspection, one can discover eight mysterious lights slowly flowing and endlessly intertwining within it, as if sealing away the most primordial power of heaven and earth.

However, in the blink of an eye, the dazzling eight-colored radiance receded and disappeared, and the gold on the surface gradually faded.

Finally, a seemingly simple and unadorned perfectly round crystal quietly floated in his palm.

"The Crystal of the Ancestral Symbol".

Lu Yu stared intently at the unassuming golden crystal, a strong desire rising within him instinctively. He opened his mouth and took a gentle breath.

The crystal then transformed into a warm, flowing light, descending down his throat and finally hovering steadily at the location of his heart. Warm golden rays emanated from his heart, like the gentlest spring water, silently nourishing his entire body.

A few breaths later, the golden light dissipated.

Lu Yu felt a lightness throughout his body, as if some invisible shackles had been quietly loosened. He slowly opened his eyes, a flash of golden light appearing in them, followed by a surge of immense soul power that swept through every meridian, bone, and dantian of his body.

After examining it carefully several times, a look of surprise and admiration flashed in his eyes.

"There's... absolutely no change?"

His physical strength remained unchanged, his total battle qi did not increase, and his soul realm remained stable at the early stage of the Heavenly Realm. However, the lightness of "loosening shackles" was real and tangible, as if some obstacles in his path had been silently smoothed away.

"What a peculiar Ancestral Symbol Crystal! Truly extraordinary!"

He composed himself, no longer dwelling on the benefits that couldn't be quantified at the moment. Right now, there were more important things to do.

Lu Yu flipped his hand, and two warm, smooth jade bottles appeared in his palm. The moment the stoppers were removed, a refreshing and delightful fragrance filled the entire quiet room.

In the jade bottle in his left hand was a pill the size of a longan, blood red in color, with nine mysterious pill patterns surrounding its surface—the Nine-Bearded Blood Ginseng Pill. Its medicinal properties were domineering, designed to temper the body and strengthen the bones and muscles.

In the jade bottle in his right hand was a perfectly round pill that emitted a soft white light—the Heavenly Spirit Pill. Its medicinal properties were mild and mellow, capable of strengthening one's fighting spirit and nourishing one's meridians. Even if one failed to break through, there would be no danger to one's life.

"Now that my battle qi and physical cultivation are both at the peak of the Dou Zun level, it's time for me to take these two pills."

A fiery glint flashed in Lu Yu's eyes. According to the Three Tribulations of the Supreme Beings in the Great Thousand Worlds, he had already overcome the Tribulation of the Divine Soul, and was still missing the Tribulation of the Physical Body and the Tribulation of Spiritual Power.

Although the battle qi system he cultivates now is slightly different from the spiritual power of the Great Thousand World, the essence of these two major challenges is the same—both are the ultimate tempering of the level of life.

He pondered for a moment, then picked up the nine-bearded blood ginseng pill, about the size of a longan and surrounded by nine red patterns, and swallowed it in one gulp.

The moment the pill entered his stomach, it transformed into a scorching torrent that swept through his limbs and bones. This domineering medicinal power was like thousands of invisible hammers, relentlessly pounding every inch of his flesh, bones, and meridians.

"hiss……"

Lu Yu gasped sharply, his knuckles turning white from the force. A wave of intense pain washed over him, his face contorting instantly, and fine beads of sweat appeared on his forehead.

“I was careless… This medicine is so potent…” He gritted his teeth, forcing out broken words, “I hope that girl Ziyan… won’t blame me…”

At this moment, he felt as if he were in a fiery furnace, his blood and qi boiling uncontrollably, every inch of his skin being torn apart and rebuilt. His bones creaked under the strain, and his meridians widened and reshaped under the impact of the medicine.

But amidst this extreme pain, he could clearly feel his body undergoing a transformation. His blood and qi surged like an angry dragon, his muscles and bones glowed with a jade-like luster, and his already formidable physique was increasing in strength at an astonishing rate.

After three days and three nights, the tearing, burning pain finally subsided.

Lu Yu slowly exhaled a breath of stale air, which was tinged with a faint blood-red hue. He stretched his limbs, and a series of crisp bone-crackling sounds immediately rang out from his body.

At this moment, he felt as light as a feather, yet every movement contained overwhelming power. Upon closer inspection, he saw that his meridians were as wide as rivers, his bones as clear as jade, and the circulation of his qi and blood faintly produced the sounds of wind and thunder.

The physical body is difficult to transcend, but it has been overcome!

"Right now, I should be able to kill several Transcendent Dou Zun with one hand without any problem, but I don't know exactly what level I'm at..."

Lu Yu felt the surging power within his body and muttered to himself. He didn't rush to take the Heavenly Spirit Pill, but instead took out the Nine Yuan Returning to Truth Jade Slip given to him by Elder Tongxuan and immersed his mind in it.

The profound mystery of the Nine Elements Returning to Truth Technique lies in "condensation" and "transformation," requiring the use of soul power as a guide to repeatedly refine and compress battle qi. Each compression is like forging fine steel, removing impurities and enhancing its essence.

He devoted himself to studying it for several days until he fully understood the method of compressing battle qi and was sure that everything was in order before he picked up the Heavenly Spirit Pill again.

"This time, we must succeed!"

His eyes narrowed, and he swallowed the Heavenly Spirit Pill. Unlike the domineering Nine-Bearded Blood Ginseng Pill, the Heavenly Spirit Pill transformed into a gentle yet powerful stream of pure energy, surging into his meridians like the tide of a spring river, and merging with his own battle qi.

In an instant, the purple-gold battle qi within his body suddenly expanded, its flow speed increased dramatically, and his entire body seemed to transform into a furnace, filled with pure energy.

"hiss……"

Lu Yu immediately cleared his mind of distractions and focused all his energy on circulating the Nine Elements Return to Truth Technique. His powerful soul force meticulously controlled the entire situation, guiding the purple-gold battle qi that permeated his body, initiating the first compression. "First Transformation, Condensation!"

Guided by immense soul power, the battle qi filling the meridians was restrained by an invisible force, slowly collapsing inward. This process was accompanied by a tremendous drain on mental energy. In the instant it was completed, the brilliance of the purple-gold battle qi seemed to have subsided slightly, but the energy ripples it created were even more powerful.

"Second Transformation, Condensation!"

The compression continued, and the purple-gold battle aura became even deeper and more solid, with that noble purple color becoming more prominent, like refined gold that had been repeatedly forged.

"Third turn!"

……

When he completed the fifth compression and successfully stepped into the fifth-level Dou Zun realm, the purple-gold Dou Qi flowing around him had become extremely condensed, like purple-gold mercury circulating endlessly within his body, emitting a heart-palpitating fluctuation.

However, just as Lu Yu was trying to guide the remaining medicinal power to break through to the sixth stage, he felt that he was running out of strength—the medicinal power of this Heavenly Spirit Pill had been exhausted.

"As expected, one Heavenly Spirit Pill can only help me reach the fifth level."

Lu Yu opened his eyes, a flash of purple-gold light appearing briefly in them, showing no surprise at the outcome.

After all, he cultivated the Great Floating Pagoda Technique, and the quality of the purple-gold battle qi he condensed far exceeded that of ordinary battle qi. Because of this, the energy required to complete the ninth revolution of Dou Zun naturally increased, far beyond what ordinary Dou Zun could achieve.

Although the Heavenly Elixir was a pill used in the Great Thousand Worlds to break through the "Difficulty of Spiritual Power," and its spiritual power was indeed higher than that of battle qi, it was still only a peak eighth-grade pill. For someone with such a solid foundation as him, the medicinal power was ultimately insufficient.

"It's alright, just follow the steps."

"Let's make another one for the next simulation."

Lu Yu remained calm and did not become anxious. He stabilized his fifth-level Dou Zun cultivation while continuing his practice, patiently waiting for the next simulation opportunity.

Time flies, and a month has passed in the blink of an eye.

When another round of simulation ended and the second Heavenly Spirit Pill appeared in his hand as he wished, a glint flashed in Lu Yu's eyes.

"This time, it will surely be a complete success!"

Without hesitation, he swallowed the pill, and the familiar, warm energy surged through his body once more. Already adept at it, he immediately activated the Nine Elements Return to Truth Technique, guiding this newfound power to attempt an attack towards the sixth stage.

With solid foundation and precise control, the breakthrough was swift and unstoppable.

Sixth transformation, successful!
Seventh transformation, complete!
Eighth transformation, complete!
When he reached the final ninth transformation, the surging purple-gold battle qi within his body had been compressed to its limit, flowing through his blood like billions of miniature purple-gold stars, radiating a magnificent divine power.

"Nine Elements Return to Truth, Condense!"

With a deep, muffled thud, the Eighth Rank Battle Qi compressed once more. An aura far more powerful and vast than before surged from his body, causing the space in the quiet room to tremble violently, and invisible ripples spread outwards.

The Nine Revolutions Dou Zun has finally achieved perfection at this moment!
Lu Yu stood up, feeling the surging purple-gold battle qi within his body, like a vast starry sea, and an unprecedented sense of power welled up within him. He casually clenched his fist, and the space in his palm emitted a humming sound as if it could shatter at any moment.

Now, he is only one step away from the realm of half-saint.

If he were to encounter that Bone Nether Saint again, even in his prime, Lu Yu was confident he could kill him on the spot!

"Now I am truly at the peak of the Dou Zun realm..."

Lu Yu chuckled softly, pushed open the stone door of the quiet room, and stepped out.

A graceful maid who had been waiting outside immediately stepped forward and said respectfully, "Congratulations on your completion of seclusion, esteemed guest. Elder Zhuli has ordered that you come to the main hall for a chat after your completion of seclusion."

"Lead the way." Lu Yu nodded slightly.

Not long after, inside the main hall of Dragon Island.

Lu Yu stepped inside, led by a maid. Elder Zhu Li, who was seated in the main seat, immediately rose to greet him. However, after taking only a few steps, he stopped abruptly, his face instantly filled with intense surprise.

"Young friend, your cultivation level is..."

Elder Zhu Li could not hide his shock. "If I remember correctly, you were at the peak of the Dou Zun level before you went into seclusion. How could you have completed the Nine Revolutions Accumulation and reached the Perfection Realm in such a short time? Such speed is truly amazing."

Zi Yan, standing to the side, also blinked her beautiful eyes curiously as she looked over.

Upon hearing this, Lu Yu smiled calmly and said, "Elder, you have keen insight. This successful breakthrough was actually achieved with the help of a pill called 'Heavenly Spirit Pill,' which greatly shortened the process of accumulating and compressing battle qi."

"Heavenly Spirit Pill?"

Elder Zhu Li frowned slightly, feeling that the name of the pill sounded familiar. Then, a glint flashed in his eyes, and he said thoughtfully, "Could it be... that this pill is related to the 'Heavenly Spirit Mushroom' that you entrusted me to search for on Dragon Island before?"

"Exactly."

Lu Yu nodded in confirmation, "That Lingzhi is an indispensable main ingredient for refining the Heavenly Spirit Pill. I was fortunate enough to obtain one by chance, which enabled me to successfully refine this pill and quickly complete the Nine Revolutions Accumulation."

Upon hearing this, Elder Zhuli suddenly understood, and his eyes filled with even greater amazement. He stroked his beard and sighed, "So that's how it is! Not only is my young friend blessed with great fortune to find such a rare and precious medicinal herb in this vast continent, but he also possesses such profound medicinal formulas and alchemy skills. I admire him greatly."

Zi Yan listened from the side, her bright eyes sparkling, and a hint of pride and smugness also appeared in her eyes.

"Elder, you flatter me. May I ask what brings you here today?"

Lu Yu smiled slightly and steered the conversation back to the main topic.

Elder Zhuli nodded with a smile, and with a flick of his sleeve, an exquisite jade slip and a storage ring appeared out of thin air and slowly flew to Lu Yu's front.

"While you were in seclusion, I had someone compile the list of the first batch of pills needed by Dragon Island, which is contained in this jade slip. As for this storage ring, it contains the various medicinal materials needed to refine these pills. Dragon Island has accumulated these materials over the years, so you don't need to worry about the medicinal materials."

He paused, then continued, "Most of the medicinal herbs are fairly common, but a few of the main ingredients are indeed rare. If you find it difficult to refine, we can discuss it further."

Upon hearing this, Lu Yu took the jade slip and storage ring, quickly scanned their contents with his soul power, and then smiled calmly, replying, "Elder, rest assured, there are no difficulties. Next month, Lingbao Pavilion will be able to deliver this batch of pills in full."

"Great! I want to go with you!"

Upon hearing this, Zi Yan, who was standing nearby, immediately rushed over excitedly, looking at Lu Yu expectantly, afraid of being left behind.

Lu Yu turned to look at her, and only then did he carefully sense the powerful aura emanating from Zi Yan. She was already a Seven-Star Dou Zun!
Clearly, during his seclusion, this girl did not slack off at all, and with the power of the Nine-Bearded Blood Ginseng Pill, her cultivation also advanced by leaps and bounds.

Before he could speak, Elder Zhuli stroked his beard and smiled, "Young friend, rest assured and let her go. During your seclusion, the spatial passage between Donglong Island and Lingbao Pavilion has been completed. If the Ancient Dragon of Taixu leads the way, it will only take a few days to travel between the two places, which is very convenient."

“This girl has been cooped up on the island for so long, it’s time for her to go out and get some fresh air.”

Upon hearing that the spatial passage had been completed, a hint of surprise and joy flashed in Lu Yu's eyes. This would indeed make things much more convenient.

He looked at Zi Yan, whose eyes were full of expectation, and finally nodded with a smile: "In that case, let's go together."

"Great!"

Upon hearing this, Zi Yan's face lit up with a smile, and she affectionately took Lu Yu's arm and gently shook it: "Lu Yu, I knew you were the best!"
