Chapter 137 Simulation Again, Sword Domain Green Robe, Innate Sword Seed!

Soon after,

The sun was high in the sky, and sunlight filtered through the gauze curtains, casting its rays onto the disheveled brocade quilt.

Little Fairy Doctor's eyelashes fluttered slightly as she slowly opened her eyes, meeting Lu Yu's smiling gaze. Lu Yu looked at her and softly asked, "How are you feeling?"

"It seems he's already at the peak of the Dou Huang realm..."

"So fast?"

Lu Yu wiped the sweat from her forehead, a look of surprise flashing in his eyes.

Little Fairy Doctor nodded happily, but hurriedly looked away when she saw his sweat-soaked clothes.

"Xian'er, you should get some rest."

He leaned down and kissed her forehead, explaining, "I'm going to the alchemy room. Now that my soul power has reached the peak of the mortal realm, it's a good time to try refining seventh-grade pills."

Little Fairy Doctor let out a soft hum in a daze, her long, black hair spreading out on the pillow like flowing water.

With a smile on his lips, Lu Yu carefully tucked the blanket around her, and with a flash of spiritual light at his fingertips, a level four spirit-gathering array was formed.

"I'll be back soon."

His warm palm gently stroked Little Fairy Doctor's cheek.

In a daze, Little Fairy Doctor unconsciously clutched his sleeve, her voice tinged with languor: "Hurry up..."

A warm feeling welled up in Lu Yu's heart, and he leaned down to place a kiss on her smooth forehead: "Soon."

……

In the days that followed, Lu Yu and Little Fairy Doctor seemed to have tasted the sweetness of success. In addition to their daily medicine refining, they devoted themselves to studying the methods recorded in the Great Emperor's Inner Classic.

In the blink of an eye, half a month has passed quietly.

Outside the alchemy room of the Mittel family, Jia Xingtian and others had been waiting respectfully for a long time.

As Lu Yu pushed open the door of the alchemy room and walked out, Jia Xingtian immediately stepped forward, presented a storage ring with both hands, and said sincerely, "Mr. Lu, these are three portions of ingredients for the Breakthrough Pill prepared according to your request. I hope you can lend a hand and refine one Breakthrough Pill for me."

As he spoke, he took out an exquisite brocade box: "This is a seventh-tier magical beast core from my royal collection, which I will use as payment for this alchemy."

Lu Yu took the storage ring and gently scanned it with his soul power. Inside, he saw three portions of ingredients for Breakthrough Pills neatly arranged, each radiating a lustrous sheen, clearly of good quality.

"The Breakthrough Pill is a peak sixth-grade pill, and its refining takes a considerable amount of time. Please wait outside, Elder Jia..."

"Of course, Mr. Lu, please go ahead..."

After a while,

Inside the alchemy room, Lu Yu sat cross-legged. He first opened a jade box filled with ice and took out a withered tree branch that looked like an ice sculpture. This was the "Frosty Marrow Branch," one of the main ingredients for refining the Breakthrough Pill.

With a light pinch of his two fingers, the biting cold immediately invaded his body. Lu Yu circulated the strange fire within his body, instantly dispelling the cold. Then, with a flick of his wrist, the Frost Marrow Branch fell precisely into the medicine cauldron.

"boom!"

Transparent flames rose up, and the Frost Marrow Branch, not to be outdone, released bursts of icy mist in resistance. However, under the continuous refining effect of the strange fire, it quickly began to melt.

Lu Yu skillfully added the other medicinal herbs one by one. Three hours later, the liquid had turned a vibrant array of colors. With focused attention, he added the final auxiliary ingredient.

"Congeal!"

With a soft shout, the medicinal liquid spun rapidly and gradually solidified with the help of the Azure Phoenix Cauldron.

"Chengdan!"

Lu Yu slammed his palm onto the cauldron, and a perfectly round pill burst forth. With lightning speed, he retrieved a jade box and stored the pill inside.

“Good quality.”

Lu Yu nodded in satisfaction, then took out the remaining two portions of materials and continued refining them.

……

Several hours later, Jia Xingtian outside the alchemy room was getting impatient.

Seeing that no unusual phenomena of alchemy had appeared in the alchemy room for a long time, he couldn't help but feel anxious: "There's been no movement for so long, could it be that the alchemy has failed?"

"What should I do? I've already incurred quite a few favors in order to gather these three portions of medicinal herbs..."

Just then, with a creak, the door to the alchemy room slowly opened.

"Old Jia, I have successfully completed my mission."

Lu Yu handed a jade box to Jia Xingtian. Inside the box lay a round, jade-like pill, the Breakthrough Pill that someone had been dreaming of.

"Thank you so much, sir. Your kindness and virtue will be forever unforgettable for the entire Gama royal family!"

Jia Xingtian's hands trembled slightly as he solemnly accepted the jade box, his eyes gleaming with excitement. After repeatedly expressing his gratitude, he took his leave.

After Jia Xingtian left, a graceful white figure arrived. Little Fairy Doctor gently took Lu Yu's arm, her beautiful eyes filled with tenderness, and said softly, "You've worked hard."

Lu Yu chuckled, took out an equally exquisite jade box, and said, "This is for you."

"Both pills have been successfully refined?" Little Fairy Doctor took the jade box with delight.

"There are three."

Lu Yu lightly tapped the tip of her nose with his fingertip and said with a smile, "Leave the last one for Lingbao Pavilion."

"As for Wuya, after he changed his cultivation method and refined his natal Gu, he has reached the half-step Dou Zong level. He will probably be able to break through on his own soon."

"This Breakthrough Pill is no longer needed."

Little Fairy Doctor nodded thoughtfully, then said softly, "I also need to go into seclusion to break through to the Dou Zong realm."

She suddenly tiptoed and gave Lu Yu a light peck on the lips, "When I come out of seclusion... I'll treat you properly."

"Oh? How will you reward me?" Lu Yu asked with a smile in his eyes.

Little Fairy Doctor blushed and whispered a few words in his ear.

"Really?" Lu Yu's eyes lit up.

"You!" Little Fairy Doctor glared at him in embarrassment and anger, then turned and walked away quickly, leaving only a lingering fragrance behind.

Watching the beautiful figure disappear, Lu Yu turned and entered the meditation room. After sitting cross-legged, he tapped his ring lightly and transmitted his thoughts: "Senior Tianhuo, thank you for protecting me outside. This alchemy has been quite taxing, and I need to recuperate for a while."

"rest assured."

The voice of Venerable Heavenly Fire rang out, and he transformed into a white shadow, darting out of the room. He waved his hand, setting up an invisible array to guard the outer chamber. Lu Yu flicked his sleeve, creating three more layers of barriers around himself. After confirming everything was foolproof, he thought to himself:
"Simulation, start!"

[Ding! Extracting a simulated identity for the host—]

[Successfully selected. Please choose one of the following three simulated identities.]

[First, a descendant of the Wood Spirit Clan—You are a descendant of a branch of the ancient Wood Spirit Clan. Living in the Great Thousand World, thanks to the long-standing friendly relations between the Wood Spirit Clan and the Pill God Clan, even though you are from a branch clan, you enjoy a comfortable life and exceptionally favorable conditions for cultivation.]

[Second, Northern Sea Dragon Cub—You are a Northern Sea Dragon Cub wandering the Hundred Spirits Continent. You possess the natural qualities of a divine beast, and upon adulthood, you may even have the potential to glimpse the Earthly Sovereign Realm. However, you are currently just a little creature at the Divine Soul Realm.]

[Third, Sword Domain Disciple—You are an outer disciple of the Sword Domain, a Saint-grade Heavenly Supreme level power in the Great Thousand World. You possess a Heavenly-grade spiritual vein and the potential to become a swordsman. You have been accepted as a disciple by Flying Stream Sword Lord, the seventh disciple of the Azure-Robed Sword Saint.]

Please make your choice——

"Great, great, after simulating for so long, I finally got some gold again..."

Lu Yu's eyes lit up when he saw the options presented in the simulation.

The second option goes without saying; I've already simulated it once. It guarantees a treasure at the Dou Wang level and at the highest level, essence blood at the Half-Emperor level—a sure-fire way to make a profit.

"However, compared to the other two, this one is a bit lacking..."

His gaze lingered on the first option: "Descendants of the Wood Spirit Clan...and on good terms with the Pill God Clan?"

Lu Yu couldn't help but click his tongue in amazement. The Pill God Clan was one of the three great alchemy holy lands, on par with the Endless Fire Domain and the Ancient Myriad Grasslands!

"Although he's just a member of a branch family, he probably can't even get close to the Dan Shen Clan..."

He rubbed his chin, thinking to himself, "If I can get my hands on one or two pills produced by the Pill God Clan, this simulation will be a huge win!"

When he saw the last option, Lu Yu's breathing became rapid:
"A disciple of the Sword Domain?! The grand-disciple of the Azure-Robed Sword Saint?!"

He almost shouted out loud, "A grand-disciple of a late-stage Saint-rank Heavenly Supreme! Do we even need to choose?"

"Simulator, turn it on, you bastard!"

Lu Yu made his choice without hesitation and eagerly started the simulation.

[Selection successful, identity loading...]

[Simulation begins——]

[In your first year, you turned six. Born with a Heavenly-grade spiritual vein and the physique of a sword seed, you caused an anomaly during your test at the Outer Domain's Spiritual Vein Hall. A dazzling sword light shot into the sky, startling the entire Outer Domain. More than a dozen elders from the Inner Domain rushed to the scene, arguing fiercely over who would accept you as their disciple…]

Just as the argument reached its climax, a streak of azure sword light ripped through the sky. The Flying Stream Sword Lord arrived on his sword, its cry echoing through the heavens: "This boy is destined for me. Will you all yield him?"

The elders present fell silent, trembling with fear. You looked up at the seventh disciple of the sword saint in blue robes and bowed without hesitation...

[Then, Sword Master Feiliu will lead you into the inner domain. The moment you step into this sacred land of sword cultivators, you will truly understand the weight of the title "Sword Saint."]

[It turns out that Flying Stream Sword Lord was the seventh disciple of the Azure Robe Sword Saint. When the Sword Saint took in seven disciples, each was exceptionally talented—his eldest disciple once fought alone in the outer realms, even as his sword fell, he still managed to slay three Demon Emperors; his third disciple challenged the Heavenly Venerable Tribulation with his sword, and although he failed, he inscribed his sword intent in the Sword Stele Forest, ensuring its eternal immortality.]

Of the seven disciples, three have already reached the Celestial Supreme Realm, while only one, limited by his talent, remains at the Spiritual Supreme Realm.

As for Feiliu Sword Master, as the Sword Saint's last direct disciple, he is currently still at the Quasi-Heavenly Supreme realm due to his short period of cultivation.

"One lineage passed down to seven sons, one family producing three immortals!"

These ten words, though brief, have been passed down through the Sword Domain for a thousand years, becoming a legend known to all. The Azure-Robed Sword Saint's discerning eye in choosing disciples has earned him the admiration of countless cultivators in the Sword Domain.

[Your master, Flying Stream Sword Lord, has cultivated for a century and has reached the threshold of tribulation. To ensure the preservation of his lineage, the Sword Saint has decreed that one must first take on a disciple before entering seclusion to break through to a higher realm. His recent journey to the outer realms is precisely to accept a disciple.]

[Since your character and conduct are still unknown, I will temporarily accept you as a disciple under a nominal title. After passing on the "Nine Heavens Sword Primordial Spirit Chapter" to you, Flying Stream Sword Lord stated frankly: If you fail to satisfy him when he emerges from seclusion, you will remain a disciple under a nominal title forever.]

[In the second year, at the age of seven, you began studying the "Nine Heavens Sword Primordial Spirit Chapter" under the guidance of Sword Master Feiliu. You had barely begun to grasp the basics of this cultivation method, personally compiled by him, when you were sent to the outer realms—just like Sword Master Feiliu had been years before, to start as a lowly menial disciple.]

[And your master then began a long period of secluded cultivation...]

All disciples of the Sword Domain are treated equally; this is an ironclad rule established by the Sword Saint.

[In the third year, you cultivated sword energy. According to the Nine Heavens Sword Primordial Spirit Chapter, using your own sword energy as your divine soul, you broke through to the Divine Soul Realm and officially became a disciple of the Outer Domain. You gained the qualification to go to the Outer Domain Library to select divine techniques.]

Among the vast collection of books in the outer realm library, you ultimately chose the top-grade divine technique specifically designed to slay the soul—the "Soul-Slaying Sword Scripture"...

[In the fourth year, thanks to your accumulated level four peak alchemy skills, you obtained a vast amount of cultivation resources. After breaking through to the Transformation Realm, you participated in the annual Outer Domain Competition.]

[With your mastery of the Emperor's Seal Technique, the Five-Wheel Fire Technique, and other unique skills, you won victory after victory, ultimately claiming first place in the Three Heavens Realm's preliminary competition. The disciples from other realms who were watching the battle discussed among themselves, believing that you were merely relying on unorthodox methods and could not be considered a true sword cultivator.]

[Faced with these criticisms, you simply smiled calmly, accepted the top-grade spiritual weapon "Azure Nether Sword" as a reward from the competition, and then drifted away.]

In the fifth year, you first broke through the Spiritual Power barrier, and then, with the help of the *Soul-Slaying Sword Scripture*, leaped to the Divine Soul barrier. Afterwards, you devoted yourself to improving the *Five Wheels of Fire Technique*, perfectly fusing it with the Burning Heaven Glazed Body, creating a unique "Body-to-Array" method—using blood and qi as the linchpin and sword qi as the array foundation, perfectly combining the physical body, spiritual power, and spiritual array to create the supreme-level sword array—the Burning Heaven Fire Sword Array. Simultaneously, relying on the abundant blood and qi of your innate sword seed, you forged a supreme spiritual body. Afterwards, you participated in that year's Outer Realm Grand Competition; with just one sword and one punch, all your opponents crumbled…

This time, no one will dare to question your abilities.

The Supreme Pill, a reward from the grand competition, will help you break through to the Supreme Realm in one fell swoop!

[That year, you were only eleven years old, and officially became a disciple of the Sword Domain's inner domain.]

[In the sixth year, your master, Flying Stream Sword Lord, successfully passed five Heavenly Venerable Tribulations and broke through to the Heavenly Supreme realm. Upon hearing of your achievements, he was greatly pleased and not only imparted to you the entire contents of the "Nine Heavens Sword Primordial Spirit Chapter," but also shared with you the complete method of forging your "Natal Sword"...]

This method was created by the Azure-Robed Sword Saint. It utilizes rare and precious objects from heaven and earth, using his own essence and blood as a catalyst and his divine soul as a furnace to forge a natal sword that is intertwined with his own life. This is the sword-forging method created by the Azure-Robed Sword Saint, and it is also one of the prerequisite techniques for cultivating the Supreme Dharma Body of the Great Thousand Worlds, the Azure Sword Profound Body.

In the seventh year, you did not rush to cultivate your natal sword technique. After careful consideration, you bid farewell to your master and decided to travel to the Southern Region of the Tianluo Continent for training. Before your departure, the Flying Stream Sword Lord gave you a life-saving sword talisman, instructing you: "In all things, simply follow your heart."

In the eighth year, you discovered something amiss within the territory of the Holy Demon Palace. Just as you were secretly investigating, the elders of the Holy Demon Palace suddenly launched a manhunt for you. You fought and retreated, maneuvering with your sword formation, but you could never shake off your pursuers…

[In the ninth year, when you were in dire straits, you resolutely shattered the sword talisman. In an instant, the spiritual power of the Flying Stream Sword Lord manifested across the heavens and earth, and with a single, chilling sword strike, annihilated all the pursuing elders of the Holy Demon Palace...]

Once the dust has settled, you will present the irrefutable evidence you have gathered of the Holy Demon Palace's collusion with the extraterrestrial evil forces before your master...

[In the tenth year, in recognition of your significant discovery that prevented the Nine Corpse Demon Emperor from reviving, Flying Stream Sword Lord granted your request and invited the Ancestral Master, Green Robe Sword Saint, to intervene and perfectly fuse the Great Sun Undying Body with the Sword Domain's natal sword technique, creating the unprecedented "Sword Sun Undying Body."]

This Dharma Body not only retains the unparalleled sharpness of the sword cultivator lineage, but also incorporates the supreme characteristic of immortality and indestructibility. After observing it, Flying Stream Sword Lord exclaimed in amazement: The potential of this Dharma Body has surpassed the Great Sun Undying Body, and is directly approaching its advanced Dharma Body, the 'Immortal Golden Body.' If it can be cultivated to perfection, it may very well rival the Azure Sword Profound Body!

However, this method has a fatal flaw—it requires devouring the essence of immortality to advance. This means that the cultivator will inevitably become an enemy of all immortal inheritors…

[Afterwards, you will record this gain into the inheritance jade slip...]

[This simulation ends——]

You can choose one of the following three items.

【1. Azure Nether Sword (Top-Grade Spiritual Weapon)】

Second, the Supreme Pill (a supreme-grade divine pill)

[3. Your inheritance jade slip]
