Chapter 90: Another Simulation - The Great Xia Dynasty, Nine Princes Struggle for the Throne!

"The first spiritual vein has been completed. I wonder if it is possible to create a second one?"

Lu Yu concealed his aura, pondered for a moment, and thought to himself.

If he remembers correctly, Mu Chen has two spiritual veins.

One of his mother's eight divine veins, and one of his own nine divine veins.

Strictly speaking, a person should be able to possess multiple spiritual veins.

"How about giving it a try?"

As soon as Lu Yu had a thought, the Floating Pagoda trembled, and a ball of dark black flame appeared.

It is the Netherworld Demon Flame!
"We can't lose either way, so there's no harm in giving it a try..."

"However, different types of fire are always mutually repelling, so I wonder about the relationships between these different types of fire veins..."

"Unfortunately, all I obtained from the simulation was the cultivation method, but no related records. I wonder if doing this is feasible..."

Lu Yu frowned slightly. Although he hesitated, he couldn't resist the temptation when he thought about the huge benefits that an additional spiritual vein would bring.

Immediately, a resolute glint flashed in his eyes. He took a deep breath and carefully manipulated the Netherworld Heart Demon Fire to circulate through his meridians.

The dark flame moved through his body like a living thing, and wherever it passed, his meridians glowed with a strange black-gold light.

"Huh? There's no rejection reaction?"

Lu Yu was surprised to find that the Netherworld Heart Demon Fire Spirit Vein he was creating not only coexisted peacefully with the previous Floating Pagoda Fire Spirit Vein, but also formed a strange balance in his dantian.

Just as he was secretly delighted, a sudden change occurred!
Two completely different flame forces suddenly clashed violently, instantly unleashing a raging inferno within his meridians. Lu Yu groaned, a trickle of blood spilling from the corner of his mouth, as black and gold flames erupted from every pore of his body.

"Not good..."

He trembled violently, and the newly formed Floating Pagoda Spirit Vein was torn apart by pain. His body instinctively rejected the Netherworld Heart Demon Fire Spirit Vein.

"It seems this road is blocked..."

Lu Yu had no choice but to force the Netherworld Demonic Flame out of his body, wipe the blood from his lips, and his face turned slightly pale.

"Since different types of different fire veins cannot coexist, what about fire veins of the same origin?"

Suddenly, a flash of inspiration struck him, and a ball of shimmering golden flame slowly appeared in his palm—it was the Floating Pagoda Flame.

However, the Floating Pagoda Fire was noticeably dimmer at this moment, clearly indicating that the condensation of the meridians had consumed a significant amount of its energy.

"Let's give it another try..."

Lu Yu stared at the shimmering golden flames dancing in his palm, a resolute glint in his eyes. He took a deep breath and slowly channeled the Floating Pagoda Fire into his body.

This time, he deliberately slowed down the speed of spiritual vein formation, allowing the power of fire to flow through the meridians like a trickle.

At first, everything seemed to be going smoothly. The newly formed second Floating Pagoda Spiritual Vein echoed the original spiritual vein, forming a double-star-encircling-the-moon pattern at the dantian. Lu Yu could even feel that the speed of the battle qi circulation within his body had more than doubled.

"As expected, fires of the same origin but different characteristics have a stronger affinity..."

However, just when he thought success was imminent, a heart-wrenching pain suddenly erupted from his limbs and bones!
"puff!"

Lu Yu trembled violently, feeling as if his meridians were being taut like bowstrings, bursting inch by inch. Hot blood surged wildly in his veins, and his internal organs felt as if they were being crushed by a heavy burden.

The once docile power of fire now became incredibly violent, surging and raging through his meridians, causing his flesh and bones to groan in unbearable strain, as if they were about to fall apart at any moment.

"cough……"

Lu Yu coughed up a mouthful of blood, collapsing to the ground like a puppet with its strings cut. He clearly felt that his body had reached its limit.

"It seems... I underestimated things..."

He wiped the blood from the corner of his mouth with a bitter smile and struggled to sit up. The two spiritual meridians within his body were still releasing immense energy, each flow bringing excruciating pain.

Left with no other choice, he had to endure the excruciating pain and slowly extract the newly formed spiritual veins.

As the second spiritual vein dissipated, Lu Yu's expression finally eased somewhat. However, this attempt not only weakened the Floating Pagoda Fire further, but also caused him considerable injuries.

"Perhaps... this is the price of greed..."

Looking at the dim and lifeless Floating Pagoda Flame in his palm, Lu Yu fell into deep thought once again.

He clearly realized that the path of cultivation must ultimately be followed step by step, and some boundaries cannot be broken by courage alone.

"wrong……"

"There was no fundamental repulsion between the different fire veins of the same origin..."

"The reason for my failure just now was that my body couldn't handle it!"

"Mu Chen possesses two meridians, so why hasn't this happened to him?"

Lu Yu frowned, carefully recalling fragments of his memories of Mu Chen.

Immediately, a glint flashed in his eyes, and he revealed a look of sudden realization:

"That's right! The nine divine meridians in Mu Chen's body were sealed by his mother Qing Yanjing with great supernatural powers until he reached the Heavenly Supreme Realm. At that time, his physical strength was sufficient to bear the power of the two meridians."

"And I am currently only at the Dou Wang realm. Even though the Floating Pagoda Spirit Vein is far inferior to the Nine Divine Veins, the domineering power it contains is far beyond what my current physique can withstand..."

"Perhaps when my cultivation advances further and my physical body becomes strong enough, I will be able to support more spiritual veins. But right now... it's obviously not possible."

"It seems all that effort was wasted..."

Lu Yu shook his head with a wry smile, then consoled himself, "But it's not entirely without gain. At least it verified this conjecture, which will be of great benefit to my future cultivation. I should have let the simulated version of myself try it first..."

At this point, he couldn't help but sigh again. After all, rare and precious things like strange fire are extremely rare, and even in simulations, they aren't always encountered. If he were to wait for his simulated self to verify this conjecture, who knows how long it would take.

Moreover, different types of different fire veins may have different characteristics. Although the Floating Pagoda Fire vein can coexist, other different fire veins of the same origin may not be able to.

The world is full of wonders. The most reliable way to understand the mysteries on the path of cultivation is through personal experience.

"Speaking of which, my simulation time is up for this month. I wonder what identity I'll get this time..."

Thinking of this, Lu Yu had a thought, and a light blue light screen slowly opened in front of him.

[Simulation count has been refreshed. Current simulation count: 1. Start simulation now?]

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

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

[First, the illegitimate son of the Hundred Spirits King—You are of noble birth, the ninety-ninth son of the Hundred Spirits King, the ruler of the Hundred Spirits Continent and a supreme earthly expert. Although your talent for cultivation is poor and you have no hope of becoming the Hundred Spirits King, you still enjoy countless cultivation resources.]

[Second, the son-in-law of the Luo Shen Clan—You are a natural-born vessel for the Luo Shen Clan, adopted by them at a young age. You grew up with Empress Luo Li of the Luo Shen Clan, and after reaching adulthood, you married into the clan, becoming the enviable son-in-law of the Luo Shen Clan.]

[Third, the Ninth Prince of the Great Xia Dynasty—You are born into the Great Xia Dynasty, a top-tier power in the Eastern Region of the Tianluo Continent, and are the ninth son of the current Xia Emperor. In the struggle for the position of Crown Prince, you and your brothers outwardly appear to be brothers, but secretly…]

Please make your choice——

Lu Yu stared at the three options before him, his eyes flashing with thoughtful light.

"The Hundred Spirits Continent, the Luo Shen Clan, the Great Xia Dynasty..."

He muttered to himself, carefully weighing the pros and cons of each option.

"Although the Hundred Spirits Continent is backed by the Heavenly Sovereign, if I were to enter as an illegitimate son, I'm afraid I wouldn't even be able to see the Hundred Spirits King, let alone an ancestor of the Heavenly Sovereign level..."

"As for the Luo Shen Clan..."

Lu Yu shook his head, thinking to himself, "The resources of the Lesser Western Heaven Realm in the Western Heaven Continent are too scarce. Currently, the Luo Shen Clan only has Luo Tian Shen, a High Earth Sovereign, left. Moreover, due to the Blood God Clan's machinations, their strength has plummeted to the Lower Earth Sovereign level..."

"This option is also not ideal..."

His gaze finally settled on the last option.

The Great Xia Dynasty—a top power in the eastern region of the Tianluo Continent!

Its ruler, Emperor Xia, is a supreme being of the highest level, and his fame spreads throughout the entire Tianluo Continent. His eldest son, Xia Yu, is a prodigy who ranks among the top five young powerhouses on the Tianluo Continent, and his fourth son, Xia Hong, is ranked twentieth.

These outstanding talents all demonstrate the profound heritage, abundant resources, and superior training system of the Great Xia Dynasty.

"That's it!"

A glint flashed in Lu Yu's eyes, and he made a decisive choice.

[Selection successful, identity loading...]

[Simulation begins——]

[In your first year, at the age of six, you awakened a level-elemental spiritual vein and were sent to the Prince's Pavilion for cultivation along with several other princes. Your instructor was a founding elder of the Great Xia Dynasty and a peerless powerhouse of the lower-level Earthly Sovereign...]

[In the second year, thanks to your precocious intelligence as a transmigrator and your existing knowledge from the real world, you repeatedly demonstrated extraordinary talent in your cultivation. This naturally attracted the attention of the other princes...]

The eldest prince, Xia Yu, often greets you with a warm smile, while the fourth prince, Xia Hong, grows increasingly sinister in his eyes. Only the eighth prince remains innocent and carefree, always secretly slipping you various exquisite pastries...

[You silently kept all of this in mind, remaining vigilant. You must know that the Great Xia Dynasty has a unique ancestral system: princes are considered adults upon reaching the age of twelve, at which point they will be assigned to various vassal states to guard their respective territories.]

[After the three-year training period, only the princes who return alive to the capital will be truly recognized as heirs by the Xia Emperor and qualified to compete for the position of Crown Prince. This ironclad rule is the fundamental reason why the Great Xia Dynasty has produced so many powerful figures throughout its history.]

[In the third year, you outwardly practiced the Xia Emperor's Manual of the Great Xia Dynasty, but secretly cultivated the Great Emperor's Inner Scripture. Your cultivation advanced by leaps and bounds, quickly standing out among the princes. At the age of eight, you broke through to the Divine Soul Realm, shocking the court and the public.]

[The Xia Emperor personally summoned you and bestowed upon you the "Nine-Turn Mystic Spirit Pill"—a pill capable of healing any injury below the level of a Supreme Being. The First Prince, Xia Yu, began frequently inviting you to spar, while the Fourth Prince, Xia Hong, secretly sent people to monitor you. However, your subsequent behavior was utterly astonishing…]

After breaking through to the Divine Soul Realm, you suddenly began to neglect your cultivation, taking in numerous maids and expanding your harem. You even abused your princely status to indulge in debauchery. Although court officials had their complaints, none dared to speak frankly against you.

In the fourth year, while the other princes successively broke through to the Divine Soul Realm, you continued to indulge in wine and women, collecting beauties...

In the fifth year, the eldest prince, Xia Yu, outshone all others at the royal hunting ceremony, slaying a ferocious beast comparable to the Three Realms at the tender age of twenty. The Xia Emperor was overjoyed and rewarded him with a lotus root of Azure Jade. All the princes vied to curry favor with him, but you remained unmoved...

In the sixth year, among the nine princes, only the eldest prince, who possessed a Heaven-level spiritual vein, broke through to the Transformation Realm, and the eighth prince broke through to the Fusion Realm. The other princes paled in comparison to these two...

Your mother sent someone to reprimand you, but you remained unmoved, continuing your pleasure-seeking and collecting beauties...

[In the seventh year, having reached the age of twelve, you were assigned to your respective posts. Before leaving, you were qualified to go to the Great Xia Dynasty's library to choose a cultivation technique. The princes vied to choose various powerful offensive divine techniques, but you alone chose a secret technique called the Heavenly Sun Divine Technique...]

[In the eighth year, you were dispatched to the Youyue Dynasty, a vassal state of the Great Xia Dynasty, as an inspector. You wielded the Prince's Sword bestowed upon you by the Xia Emperor, granting you the power to execute first and report later—a privilege granted by imperial authority...]

While the other princes were diligently practicing, you were also "cultivating diligently"—after mastering the Heavenly Yang Divine Technique to its highest level, you combined it with the profound mysteries of the Great Emperor's Inner Classic, engaging in dual cultivation with the many women with special physiques that you had carefully collected over the past five years.

[This includes one Celestial Vein, three Earthly Vein, twenty Human Vein, and four women with special constitutions. Under this fusion of Yin and Yang, your aptitude has broken through its limitations, leaping to the Celestial level...]

[In the ninth year, you used your authority to plunder all kinds of rare and precious materials from the Youyue Dynasty, and with the help of a level six celestial vein, your cultivation advanced by leaps and bounds...]

In just one year, he broke through the three realms of Fusion, Transformation, and Heaven-Reaching, reaching a level of physical prowess that shook the court and the public...

In the tenth year, Emperor Xia summoned all the princes back to court to report on their duties. By this time, you had broken through to the second level of the Divine Soul Realm, second only to the eldest prince, Xia Yu, and overshadowing the other princes, making you the most prominent figure of the time…

On the return journey, assassins from all sides swarmed in. Below the Supreme Realm, Spirit Array Masters laid down killing formations, Spirit Insect Masters commanded poisonous creatures, and Puppet Masters controlled battle puppets...

However, you thwarted all these assassination attempts. Even more remarkably, thanks to the secret cultivation techniques you used with your many Daoist partners, you were able to return to the capital unscathed...

Meanwhile, the eldest prince, Xia Yu, and the seriously injured fourth prince, Xia Hong, also arrived in the capital one after another...

The remaining six princes all perished in their respective fiefdoms...

At dawn the following day, Emperor Xia summoned his three sons to Xuanwu Gate to discuss the position of Crown Prince...

[At the Xuanwu Gate, you and Xia Yu clashed instantly, sparking an epic battle. After hundreds of rounds, you finally unleashed the Emperor's Seal Technique at its peak, combined with a secret meridian-opening method, unleashing terrifying power comparable to a great divine technique. This severely injured Xia Yu, and you took his Mustard Seed Bracelet…]

[Then, to Xia Hong's astonishment, you stepped into the Heavenly King's Hall first...]

The following day, Emperor Xia officially issued an edict, appointing you as Crown Prince...

[A method for cultivating the Dharma Body of the Emperor, preceding the Dharma Body of the Great Heavenly King, a replica of the sacred artifact Mountain and River Seal, and a complete cultivation manual of the Xia Emperor's Technique...]

After some thought, you decided to transfer all your winnings into the mustard seed bracelet...

[This simulation ends——]

You can choose one of the following three items.

【1. Mountain and River Seal (Low-Tier Sacred Relic)】

Second, the Nine-Turn Profound Spirit Pill (Supreme-Grade Divine Pill)

【Third, Azure Jade Lotus Root (Supreme-grade Spiritual Object)】
