Chapter 138 Natal Sword? Embryonic Dharma Body!
"There's actually a Supreme Pill..."

Lu Yu looked at the options presented in this simulation, stroked his chin, and a look of surprise flashed in his eyes.

It should be understood that in the vast world, in order to advance to the Supreme Realm, in addition to overcoming the three minor tribulations of the Supreme Realm and reaching the peak of the Divine Soul Tribulation, one also needs a large amount of Supreme Spiritual Liquid as support before attempting to break through to the Supreme Realm.

Such a breakthrough is naturally not guaranteed to succeed. If it fails, the Qi Sea will shatter, resulting in the loss of all cultivation and the loss of all the Supreme Spiritual Liquid accumulated through hard work.

As a result, pills that help break through to the Supreme Realm came into being. These are the Supreme Pills. Although having the Supreme Pills does not guarantee absolute success, the success rate will certainly be much higher.

However, while this kind of pill is precious, it is not necessarily rare. In the vast world, its value is roughly equivalent to a low-grade divine artifact. Most king-level forces with a fifth-grade supreme expert in charge can produce one or two of these pills.

"If I remember correctly, the champion of the Five Great Academies Spiritual Academy Tournament is a Supreme Pill. The identity I simulate most often is that of an academy student. With careful planning, the probability of getting this is quite high."

"As for the top-grade spiritual weapon, the Azure Nether Sword, it has the lowest value, so there is no need to choose it."

"As for that inheritance jade slip, the Sword Sun Undying Body, when cultivated to perfection, is comparable to the Azure Sword Profound Body..."

A glint of light flashed in Lu Yu's eyes. As far as he knew, the Azure Sword Profound Body ranked tenth among the ninety-nine supreme avatars, and in terms of power, it was second only to the five original avatars.

The value of this method of Dharma Body cultivation is immeasurable, perhaps comparable to an ancient divine technique. After all, not everyone can inherit the five original Dharma Bodies, but the Dharma Bodies ranked after the five original Dharma Bodies are not necessarily so.

"The only hidden danger is that this Dharma Body needs to devour the Immortal Source to advance. That's not a problem, though. As long as I don't say anything, who would know that my Dharma Body needs to devour the Immortal Source? Casually ambushing people in the simulation is just indiscriminate killing, isn't it?"

"Compared to the Azure Sword Profound Body, which has a distinguished lineage, and the five primordial bodies that have been hidden away for many years, this Sword Yang Imperishable Body is probably the highest-grade body I can obtain at the moment. If I can devour that eternally immortal body in the future, that would be even better..."

A thoughtful look flashed in Lu Yu's eyes, and he decided on his choice for this simulation.

The next moment, a gilded jade slip appeared in his hand.

In an instant, a massive amount of information flooded into my mind:
"The Earth-Rank Advanced Soul Cultivation Technique: Soul-Slaying Sword Scripture; the Heavenly Supreme-Rank Technique: Nine Heavens Sword Primordial Spirit Chapter; the Supreme-Rank Array: Heaven-Burning Blazing Fire Sword Array; the Method for Forging Natal Swords; the Method for Cultivating the Great Sun Undying Body; the Method for Cultivating the Sword Yang Undying Body..."

After a long while, Lu Yu slowly opened his eyes, rubbed his throbbing temples, and processed the massive amount of information filling his mind.

After a brief moment of contemplation, he took out two jade slips and recorded the Soul-Slaying Sword Scripture and the method for forging his natal sword into them.

These two techniques can not only be practiced by oneself, but also passed on to those around them.

"This Soul-Slaying Sword Scripture has come at just the right time. After my soul power reached the peak of the Mortal Realm, I was still worried about how to break through to the Spirit Realm. As an eighth-grade pill, the Bright Soul Pill cannot be refined without a Spirit Realm soul, but if I want to break through to the Spirit Realm, I must use the Bright Soul Pill as an aid..."

"If I were in the Fire Spirit Clan, obtaining these pills wouldn't be a problem. The problem is that I'm in the Dou Qi Continent. I've managed to gather all the necessary ingredients by scavenging various forces in the Scorpion Mountain Range and the Black Corner Region, but I haven't found a single one of the three main ingredients..."

"This is not as good as practicing the Zanpakuto Scripture that I just acquired..."

Suddenly, Lu Yu paused, a thoughtful look flashing in his eyes, and muttered to himself, "Heavenly Fire Forging God and Soul-Slaying Sword Scripture are both soul cultivation techniques, one with fire attribute and the other without attribute. Can they be cultivated together?"

"The Great Floating Pagoda Technique and the Burning Technique cannot be practiced simultaneously because the meridians in the body are intricate and complex, and there are conflicts in the flow of energy in some areas, making it difficult to practice them together..."

"The Great Emperor's Inner Classic is a rather unique cultivation method. It mainly cultivates Yin and Yang energies and has a strong inclusiveness, which is why I am able to practice it as well..."

"But soul cultivation techniques—the soul is formless and intangible, and there are no meridians—can one cultivate different techniques simultaneously?"

Lu Yu stroked his chin, a glint of light flashing in his eyes. The more he thought about it, the more feasible it seemed.

Although there are almost no soul cultivation techniques on the Dou Qi Continent, and it is difficult to find special cases of cultivating two soul cultivation techniques simultaneously, with his current skills as a seventh-grade alchemist, it would not be a big deal to give it a try, at most he would lose some soul power.

If you're really worried about the risks, you can always let your simulated self try it out next time. It's the simulated me that dies, not the real me.

What does this have to do with me?
"It's decided. Next time, I'll let the simulated version of myself try it out. If it succeeds, by cultivating two soul techniques simultaneously, the quality of my soul power will definitely far surpass that of others at the same level. At that time, I can use the Soul-Slaying Sword Scripture to break through to the Spirit Realm, and then use the soul from the Spirit Realm to cultivate the Fire Transformation step. Even without the aid of the Bright Soul Pill, I have a very high chance of succeeding..."

A hint of excitement flashed in Lu Yu's eyes as he spoke with great interest.

After all, the reason why the transformation into fire is so dangerous is that mortal souls have difficulty controlling themselves and will spontaneously combust if they are not careful. However, using a spiritual soul to break through into fire is comparable to an eighth-grade alchemist refining a seventh-grade peak pill. It is not only easy, but also a matter of no difficulty.

"Let's take another look. The method for forging this natal sword is one of the prerequisite techniques for the Azure Sword Profound Body. It must be quite extraordinary..."

Lu Yu put away the two jade slips, leaving only the jade slip containing the method for forging his natal sword, and began to study it carefully once again.

After a moment, he put down the jade slip, a thoughtful look flashing in his eyes, and muttered to himself, "So the method for forging this natal sword is actually the method for forging the Azure Profound Sword, the prerequisite for cultivating the Azure Sword Profound Body."

He pondered deeply and sorted out the key points: "This method is divided into three refinements: First, refine the sword embryo: select a spiritual object of heaven and earth that is compatible with one's own cultivation method, melt it into a prototype of the sword embryo, and then use essence blood to sharpen it and forge a unique spiritual sword.

Second Refinement of Qi and Blood: Integrate the body's Qi and blood with the sword to generate unique blood Qi, laying the foundation for subsequent Spirit Refinement;
The third refinement of spiritual essence: Harvesting the light of one's spirit into the sword's soul, ultimately uniting life and essence to create the Azure Profound Sword Embryo.

"Afterwards, the sword will need to be continuously tempered with rare fire, mysterious lightning, and other spiritual materials of heaven and earth to maintain its sharpness and continuously improve its grade."

Lu Yu stroked his chin thoughtfully: "It is called a sword embryo, but it is more like a nascent form of a Dharma body. It can be used before the Supreme Realm. After breaking through to the Supreme Realm, if one does not wish to specialize in the Azure Profound Sword, one can reforge the Azure Profound Sword and switch to cultivating other Supreme Dharma bodies... This design is quite comprehensive."

"Looking at it this way, the Azure Profound Sword seems to have a similar function to my Floating Pagoda, except that it focuses more on killing. I could cultivate it and, after reaching the Supreme level, switch to cultivating the Sword Yang Undying Body or other Dharma bodies..."

"only……"

Lu Yu frowned slightly, pondering, "Where should I look for a spiritual object that matches my own attributes?"

Suddenly, as if struck by a revelation, he slapped his forehead: "How could I have forgotten about it!"

As he spoke, a piece of metal, entirely black and covered with crimson patterns, appeared in his palm—it was the Fallen Heart Flame companion he had obtained in the Canaan Academy library, the Fallen God Black Iron!

"but……"

Lu Yu pondered for a moment, thinking to himself, "This alone is not enough to forge a perfect sword embryo. In order to create a better natal sword, it would be better to find an eighth-order fire attribute material as the main material, and then use this Fallen God Profound Iron as a base material to fuse in. After all, it is a companion material of a different fire, which should greatly improve the compatibility."

Having made up his mind, he temporarily put aside the refining process and got up to leave the seclusion.

……

Not long after, Lu Yu finished his seclusion. As soon as he stepped out of the meditation room, he saw Venerable Tianhuo wave his sleeve, and the surrounding spiritual seals flickered. The spiritual array that enveloped him instantly dissipated, turning into specks of light and scattering away.

"Senior Tianhuo, how have you been recovering lately?" Lu Yu asked with a smile.

The illusory figure of Venerable Heavenly Fire swayed slightly, his voice tinged with relief: "Thanks to the soul pills provided by the Pavilion Master, I am now close to the Spirit Realm. Combined with the spirit array bestowed upon me by the Pavilion Master, I can even fight against a Dou Zong expert. However..."

Lu Yu smiled knowingly and asked, "Senior, are you worried about your physical body?"

Upon hearing this, Venerable Tianhuo was taken aback. His illusory figure trembled violently, and a glint of light flashed in his eyes. He subconsciously asked, "Does the Pavilion Master have a solution?"

Lu Yu nodded and said, "There is indeed a solution."

Upon hearing this, Venerable Heavenly Fire could not hide his excitement, "Is what you say true, Pavilion Master!"

Lu Yu smiled without saying a word. With a flick of his finger, a jade slip appeared.

The Heavenly Fire Venerable's soul power swept across the area, and the contents recorded within were immediately revealed: the formula for the Bone-Growing and Blood-Melting Pill, the essence blood of a seventh-tier magical beast, the remains of a Dou Zong powerhouse, and three extraordinary flames...

After a moment, Venerable Heavenly Fire's voice trembled slightly, tinged with excitement, as he said, "These materials aren't too rare..."

"As for the three great strange flames, the Pavilion Master's Floating Pagoda Flame, Miss Xian'er's Netherworld Poison Flame, and my Fallen Heart Flame, the three great strange flames are now complete."

Upon hearing this, Lu Yu nodded: "That's right. The most difficult part of this method of rebuilding the physical body, the strange fire, has been solved. The essence blood of demonic beasts and the remains of Dou Zong are not hard to find. However, this Life Bone Fusion Blood Pill is a peak seventh-grade pill. It is a legendary pill that can revive anyone who has a breath left. Its value is comparable to an ordinary eighth-grade pill."

"The medicinal materials required for this pill are numerous and complex, and it is probably difficult for the Black Corner Region to gather them all. It may be necessary to go to the Pill Tower in the Central State to collect them."

He paused, then said with a hint of apology, "Besides, I've only recently entered the seventh rank, and I still need some time to hone my skills in refining this pill. But rest assured, senior, once I've finished dealing with my current matters, I will do my utmost to rebuild your physical body."

Upon hearing this, Venerable Heavenly Fire let out a hearty laugh: "Hahaha, I've waited all these years, what's a little while longer?"

Seeing the magnanimous appearance of Venerable Heavenly Fire, Lu Yu couldn't help but smile.

This method of rebuilding the physical body was recorded in the seventh-grade alchemist inheritance that Yao Lao had given him. However, whether by coincidence or design, before he could truly reach the seventh grade, Yao Lao had already pretended to fall into a deep sleep, so that he could not disturb him rashly.

Over the next few days, Lu Yu and Venerable Tianhuo waited for Xian'er to break through while discussing the Dao of Spirit Arrays. One was a former Dou Zun powerhouse, and the other was a highly talented seventh-grade alchemist. Through their exchanges, they both benefited greatly.

The sky was clear and the air was crisp on this day.

Suddenly, in a secluded courtyard, the energy of heaven and earth converged wildly, forming a visible energy vortex. Little Fairy Doctor sat cross-legged in the center of a level four spirit-gathering array, her battle aura surging like a tide, her clothes fluttering without wind.

Lu Yu and Venerable Tianhuo sensed the fluctuation at the same time and smiled at each other.

"It seems Xian'er is about to break through." A look of relief flashed in Lu Yu's eyes.

Venerable Tianhuo stroked his beard and sighed, "An eighteen-year-old Dou Zong expert, although not as good as the Pavilion Master, is still a top-notch prodigy in the Central Plains. It is truly enviable that the Pavilion Master has such a wife."

Upon hearing this, a hint of tenderness flashed in Lu Yu's eyes as he gazed at the graceful figure surrounded by an energy vortex in the distance. There, Little Fairy Doctor's black hair fluttered in the wind, her battle aura surging and solidifying under the enhancement of the Spirit Gathering Array.

The illusory figure of Venerable Heavenly Fire swayed slightly, his tone tinged with emotion as he said, "When I traveled through the Central Continent, I saw many so-called prodigies. But those who reached the Dou Zong realm at the age of eighteen were all heirs nurtured by various powerful forces."

He paused, then added meaningfully, "What's even more remarkable is that this girl is kind-hearted and has a sincere heart for the Pavilion Master. In all my years of life, I've seen too many couples who are bound together by interests, but those who are so compatible and in love like you two are truly rare."

Lu Yu's gaze softened as he recalled the moments he had shared with Little Fairy Doctor over the years. From their first encounter in Qingshan Town to her current status as a powerful Dou Zong expert, this stubborn girl had indeed always maintained her pure heart.

Just as the two were talking, the energy vortex in the courtyard suddenly contracted violently, all of it surging into Little Fairy Doctor's body. She slowly opened her eyes, a glint of light flashing across them, her aura already stabilized at the Dou Zong realm.

"Success."

A relieved smile appeared on Lu Yu's face. Just as he was about to step forward, he saw Little Fairy Doctor suddenly turn her head to look in their direction, a gentle curve appearing on her lips.

Seeing this, Venerable Heavenly Fire wisely transformed into a streak of light and returned to his storage ring, leaving behind only a teasing remark: "Young people, this old man will not disturb you any longer..."

"Brother Lu..."

Little Fairy Doctor's pretty face flushed slightly, her eyes sparkling with a hint of shyness. Having just broken through to the Dou Zong realm, her aura was not yet fully contained, making her skin appear even more like snow in the sunlight, radiant and captivating.

Just as Lu Yu was about to step forward, his brow twitched slightly, and he turned to look towards the courtyard gate. He saw Xiao Yan walking quickly towards him, a hint of hesitation on his face.

"Brother Lu."

Xiao Yan clasped his hands in a salute, then said solemnly, "I want to go back to Wutan City to see my father and clansmen first."

Lu Yu nodded upon hearing this, took out a glowing conch shell from his storage ring, and said, "Take this sound transmission conch shell and contact me anytime if you need anything."

He paused, then smiled and said, "Give my regards to Uncle Xiao."

Xiao Yan took the conch shell, grinned, and said, "I'll definitely take it with me! I'll be going now."

After saying that, he waved his hand casually and turned to leave.

Watching Xiao Yan's departing figure, Little Fairy Doctor said softly, "Little Brother Xiao Yan does seem to miss home."

Lu Yu naturally put his arm around her slender waist and chuckled, "This guy has always been loyal and sentimental."

Then, his tone softened, and he said with concern, "You need to recuperate after breaking through, I'll stay with you..."

Little Fairy Doctor glanced at him helplessly, knowing exactly how he was going to keep her company, and said coquettishly, "You big pervert!"
