Chapter 159 Another Simulation: The Western Heaven Battle Hall, Mu Chen's Lifelong Enemy!
Upon hearing this, Lu Yu bowed respectfully, his expression unchanged, and began to recount Yao Chen's experiences over the years.

From being betrayed by Han Feng to residing in the Bone Flame Ring, from taking Xiao Yan as his disciple to now restoring his spiritual realm cultivation, his words were sincere and logical, without any exaggeration or concealment.

Xuan Yi listened quietly, her eyes, as cold as stars, sometimes flickering, sometimes dimming. When she heard that Yao Chen had been betrayed by Han Feng, her jade-like fingers in her sleeve clenched unconsciously; when she heard that Yao Chen had taken Xiao Yan as his disciple, a barely perceptible smile appeared on her lips.

After Lu Yu finished speaking the last word, the courtyard fell silent. A morning breeze blew by, lifting a strand of black hair from her black dress. She remained silent for a long time before slowly saying, "That old man... is still so stubborn."

"Only now, in this state, do you come begging to me..."

Her tone remained cool, but it was a bit softer than before.

Suddenly, she waved her sleeve, and a crystal-clear jade box floated to Lu Yu's front: "Since you have received guidance from Yao Chen, you can be considered half a disciple of his. Consider this Blood Essence Demon Fruit a small gift for our first meeting."

He paused, then added, "As for Yao Chen's Bone-Growing and Blood-Melting Pill, you don't need to worry about it. I will refine it myself."

Lu Yu took the jade box and saw a blood-red fruit inside, the final ingredient of the Bone-Growing and Blood-Melting Pill. He was about to thank him when Xuan Yi continued:

“Feng Xian said you have reached the Spirit Realm, but I didn’t believe it at first.”

Her gaze swept over Lu Yu with lightning speed, a hint of approval flashing in her eyes. She said, "Seeing you today, it's not an exaggeration. That old guy's judgment is as sharp as ever."

"boom!"

The door to the room was suddenly pushed open, and Zi Yan walked out, rubbing her sleepy eyes: "What's all the noise so early in the morning..." Before she could finish speaking, she suddenly stared wide-eyed at Xuan Yi, "Huh? You have such a strong energy fluctuation!"

Little Fairy Doctor arrived quietly, gently took Zi Yan's hand, and bowed to Xuan Yi.

Xuan Yi's gaze sharpened: "The Ancient Dragon of the Void?"

Just then, the space rippled, and Venerable Feng appeared in a flash. Seeing Xuan Yi in the courtyard, his lips twitched, and he thought to himself: This woman runs faster than anyone else the moment she hears news of Yao Chen, truly…

"Xuan Yi, you've arrived quickly."

Venerable Feng shook his head helplessly and said, "I haven't even had a chance to take them to the inner domain yet, but you've already arrived in the outer domain..."

The man in black snorted coldly: "Why should I explain my actions to you?"

With that, she flicked her sleeve, and the light transformed into starlight that dissipated into the morning glow.

Venerable Feng shook his head with a wry smile, then looked at Lu Yu and explained, "This woman is still so impatient... But since she has agreed to help, you don't need to worry about Yao Chen's pill."

He stroked his beard and continued, "I will wait here for the time being until she has refined the elixir, and then we will set off for the Northwest together."

"The Pill Tower is the holy land of all alchemists in the world. Young friend, you have just broken through to the Spirit Realm. Why not hone your skills here and exchange ideas with the alchemists here? This will also help you improve your own skills."

Lu Yu nodded and cupped his hands in thanks, saying, "Thank you for your guidance, senior."

After Venerable Feng left, Lu Yu returned to his meditation room.

He sat cross-legged and took out the Blood Essence Demon Fruit to examine it closely. The fruit was entirely blood-red and emitted a rich aura of blood energy, clearly indicating its excellent quality.

After examining it for a moment, he put the jade box containing the Blood Essence Demon Fruit into his storage ring, then swallowed a Soul Nourishing Pill to adjust his condition to its best before starting his cultivation.

Although they had been traveling through the spatial passage during this period, they were unable to absorb the surrounding天地能量 (heaven and earth energy) to cultivate their fighting qi.

However, his cultivation of soul power has never slackened. Now that he has broken through to the second level of the Soul-Slaying Sword Scripture, it is time for him to break through to the Fire Transformation Realm of the Heavenly Fire Forging God Technique.

Lu Yu closed his eyes and concentrated, his soul power suddenly surging. The Netherworld Demonic Flame danced deep within his soul, gradually merging with the vast soul power. Between his brows, the phantom of a jet-black flaming sword flickered, radiating a chilling aura.

"Transform into fire!"

With a low shout, a raging black flame instantly erupted in his mind. Countless long needles formed from flames rained down on the flaming longsword, hissing as they were forged. The longsword shrank and condensed continuously in the flames, as if undergoing a thousand hammer blows.

In a daze, countless illusions of thunder appeared before Lu Yu's eyes, only to be instantly burned to nothingness by the fire of his soul.

"Boom!"

A deafening thunderous roar resounded deep within his soul, and the flaming longsword suddenly transformed. First, it transformed into a humanoid flame, wielding the black flame longsword; then, it abruptly contracted, disappearing entirely into the sword's body.

In an instant, Lu Yu felt his soul power surge, and his cultivation, which was just beginning to enter the Spirit Realm, was instantly stabilized, directly climbing to the peak of the early stage of the Spirit Realm!

"boom!"

Lu Yu suddenly opened his eyes and exhaled, a vast, invisible thunderous sound spreading out as if it were a tangible entity, causing the protective array in the quiet room to tremble violently and ripples to appear on the light screen.

A moment later, after the aftershocks subsided, he slowly suppressed his aura.

"Soul-Slaying Sword Scripture, Heavenly Fire Forging God Technique..."

He pondered the profound mysteries of these two soul cultivation techniques, a glint of light flashing in his eyes. His hand seals shifted instantly, and a small, ethereal, jet-black sword materialized at his fingertips. The sword was no more than three inches long, yet it emanated a terrifyingly high temperature that sent chills down one's spine.

"go with!"

With a flick of his finger, a small black sword shot out. The array in the quiet room was easily pierced like paper, leaving a hole about an inch in size, with black flames slowly burning at the edge.

"Excellent!"

Lu Yu's eyes lit up with surprise, "A soul fire tempered by the Netherworld Demonic Flame naturally possesses the power of soul thunder, and when combined with the sword light of the Soul-Slaying Sword Scripture..."

He stared at the small black sword that had reformed at his fingertips. "This power is no less than that of an ordinary soul skill."

After pondering for a moment, Lu Yu stroked his chin and suddenly laughed loudly, "This technique has both the power of thunderous sound that shakes the soul and the effect of sword light that severs the soul, so how about we call it—"

"Netherworld Thunder Sound Sword!"

……

A few days later,

Lu Yu sat cross-legged in the quiet room, while Venerable Tianhuo stood guard outside. Before him, a pale blue light screen slowly unfolded.

"The one-month period has ended; it's time for another simulation."

"Now I am an eight-star Dou Zong, not far from becoming a Dou Zun. Senior Tian Huo has also recovered to the Spirit Realm and can set up a level five Spirit Gathering Array to supply Dou Zun experts with cultivation. Next, it is time to plan my breakthrough to Dou Zun."

"Ideally, I could obtain a supreme-level spiritual artifact to accelerate energy accumulation..."

As Lu Yu thought this, his mind stirred, and in an instant, the light screen in front of him began to change.

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

[Selection successful. Please choose one of the following three roles.]

[I. Immortal Fox Sect Disciple – You are an outer disciple of the Immortal Fox Sect, a supreme power on the Shang Continent. You are kept by an inner disciple and have lived a life of decadent luxury since entering the sect.] [II. Spirit Insect Clan Descendant – You are a descendant of one of the three main lineages of the Spirit Insect Clan: Feather, Scale, and Insect. Although you belong to a main lineage, your bloodline is thin, resulting in a low status within the clan.]

[Third, Disciple of the Western Heaven Battle Hall—You are a member of the Blood God Clan in the Lesser Western Heaven Realm of the Western Heaven Continent. Due to your exceptional talent, you were sent to the Western Heaven Battle Hall, one of the super powers of the Great Thousand Worlds and the ruler of the Western Heaven Continent, for cultivation from a young age.]

Please make your choice——

"The Immortal Fox Sect?"

Lu Yu stared at the first option on the screen, his brows furrowing slightly. He pondered for a moment before recalling some information about this sect: "So it's the sect that tried to seduce the Martial Ancestor after he ascended to the Great Thousand World. Just a mere Sovereign power..."

"It's fortunate that the Martial Realm Mistress, Ling Qingzhu, was magnanimous and didn't cause trouble for that Celestial Fox Lady..."

When his gaze shifted to the second option, he shook his head: "Although the insect bloodline of the Spirit Insect Clan is strong, the descendants with thin bloodlines have too low a starting point."

Then, Lu Yu's gaze fell on the last option, and a smile involuntarily appeared on his lips. He thought to himself, "This is indeed a good option."

"The Western Heaven Battle Hall, isn't this the option I simulated before?"

"It's still a Celestial Sovereign-level power, with a much deeper foundation than a Spiritual Sovereign-level power like the Spirit Insect Clan..."

With this in mind, Lu Yu quickly made his choice.

[Selection successful! Identity loading...]

[Simulation begins——]

[In the first year, thanks to your outstanding talent for cultivation, and with the Blood God Clan Chief bribing Elder Winter of the Western Heaven Battle Hall with a large sum of money, you successfully obtained the qualification to enter the Battle Hall for cultivation.]

[Due to your precognitive advantage, in this life you began by cultivating the Nine Heavens Sword Primordial Spirit Chapter as your primary cultivation technique. Considering that the Sword Domain is located in the far east of the Great Thousand World, while the Western Heaven Battle Hall is in the far west, you are not worried that this technique will be recognized by the people of the Western Heaven Battle Hall.]

[In the second year, relying on your rich cultivation experience, you broke through to the Divine Soul Realm. After careful consideration, you decided to join the Spirit Consort Palace, one of the Four Palaces...]

[This year, you didn't sit idly by. From the very beginning, you displayed astonishing talent in alchemy, mastering the basics in just a few months and becoming a fourth-level alchemist within a year. Coupled with your background as a member of the Blood God Clan, you quickly became a highly sought-after prodigy in the Spirit Consort Palace.]

In the third year, for the purpose of refining pills, you asked the Blood God Clan for a Heavenly Spirit Flame. The Blood God Clan had no suspicions. An elder of the Blood God Clan personally took action, slaughtering tens of thousands of spirit beasts, using their essence and souls to condense a Myriad Beast Spirit Flame for you...

[Afterwards, you refined the Myriad Beast Spirit Fire, broke through to the Heavenly Realm, created a Level 4 Earth Vein, and your alchemy skills naturally advanced to Level 5, attracting the attention of the higher-ups of the Spirit Consort Palace.]

[In the same year, Consort Ling personally summoned you, intending to take you as her personal disciple...]

Without hesitation, you performed the three kneelings and nine kowtows ceremony, formally becoming a disciple of Ling Feizi. From that moment on, the Western Heaven War Emperor became your grandmaster, and you became a renowned third-generation cultivator throughout the entire Western Heaven Continent.

The news reached the Blood God Clan, causing a great stir. The Clan Chief broke through his seclusion and personally went to the Western Heaven Battle Hall to welcome you back to the clan, where he bestowed upon you the title of Holy Son of the Blood God Clan…

In the fourth year, with the full support of the Blood God Clan, you successfully overcame the three minor tribulations of the Supreme Realm, reaching the peak of the Divine Soul Tribulation. During this time, you secretly discovered information about Mu Chen, confirming that he was still studying at the Northern Cang Spiritual Academy.

[So you immediately ordered the recall of Xue Tianhe from the Blood God Academy, while you disguised yourself and prepared to participate in the upcoming Spirit Academy Tournament as Xue Tianhe...]

[In the third month, the Spirit Academy Tournament was held as scheduled, and your team swept through the competition. Using the clan's specially crafted Spirit-Seeking Compass, you quickly located the trail of the Luo Shen clan's bloodline.]

In the fourth month, you discovered traces of the Luo Shen Clan's bloodline. As expected, Luo Li was traveling with Mu Chen. You immediately led a group of Blood God Clan prodigies to surround and trap them...

[Facing Mu Chen, you showed no mercy and unleashed your full power. The Five-Round Blazing Fire Array sealed off the surrounding space, and you even went so far as to self-destruct the low-grade divine artifact, the Blood Demon Arm, severely injuring Mu Chen with a single blow...]

[Afterwards, under Mu Chen's bloodshot gaze, you forcibly abducted Luo Li! At this moment, you had already planned everything: Qing Yanjing's spiritual avatar had been exhausted, Jiu You was still asleep, and Mu Chen was at his weakest moment...]

[You seized the opportunity to plant a Supreme-level Blood Demon Poison in Mu Chen, completely severing his possibility of cultivation advancement. Just then, an unexpected event occurred—Jiuyou sensed Mu Chen's danger and awakened prematurely, intending to kill you. At the critical moment, the spiritual power avatar of Ling Feizi manifested within you, instantly killing Jiuyou with a single palm strike…]

In the instant of her fall, Jiuyou gazed deeply at Mu Chen, sacrificing her own annihilation to forcefully sever the bloodline link with him through a backlash...

Luo Li was taken from him, Jiu You perished, and Mu Chen descended into utter madness. But you know, this is far from enough...

Only by completely shattering Mu Chen's Dao heart can we secure a glimmer of hope for you and the Blood God Clan!

[Subsequently, urged by Ling Feizi, you left the Ruins Continent, thus ending the competition.]

Meanwhile, you arranged for a Blood God Clan elder to disguise himself as the Ring Elder to approach Mu Chen and secretly guide his cultivation path...

[In the fifth year, you successfully broke through to the Supreme Realm. Consort Ling summoned you to the inner palace and imparted to you the first two volumes of the Great Emperor's Inner Scripture—the Foundation Establishment Scroll and the Supreme Scroll. To your astonishment, unlike the Foundation Establishment Scroll which improves aptitude, the cultivation method recorded in the Supreme Scroll can actually enhance the quality of one's own spiritual veins through dual cultivation…]

After much deliberation, you used the survival of the Luo Shen clan as leverage to force Luo Li to marry you. On their wedding night, you used a secret technique to conceive a child with her, showering her with care and affection every day, treating her with genuine affection...

As time went on, Luo Li eventually softened. You even collaborated with the Blood God Clan Chief in a charade—the Chief threatened to massacre the Luo God Clan, while you "vehemently dissuaded" him, ultimately saving the Luo God Clan. Luo Li was extremely grateful for this…

In the sixth year, under the guidance of the "ring-wielding old man," Mu Chen gradually fell into the demonic path. He discovered that his surroundings were full of deceit and treachery, and ultimately chose to abandon the Great Floating Pagoda Technique and instead cultivate the Blood God Clan's secret technique, the Blood Demon Devouring Heaven Art...

Meanwhile, you are working diligently, shuttling between the Spirit Consort Palace and the Blood God Clan, serving your master well while also comforting Luo Li, who is pregnant again...

In the seventh year, Mu Chen, at the cost of exhausting his potential, achieved the Seventh Rank Supreme in a single year. His entire body was enveloped in bloodthirsty aura, and his eyes were bloodshot as he lay in ambush outside the Blood God Clan...

[You knew the time was right, so you deliberately went out to train. When Mu Chen's fatal blow came, Luo Li stepped forward and shielded you behind her: "Stop! He...he's been very good to me and the child..."]

[Mu Chen was struck dumb. Looking at the infant in Luo Li's arms, who resembled him so closely, and then thinking of the unharmed Luo Shen Clan, he finally realized that it had all been nothing but self-deception. He gave a bitter laugh and disappeared into the vast night without looking back...]

[In the eighth year, Mu Chen, having lost his fighting spirit, completely disappeared, and your heart finally settled. The crisis of the Blood God Clan's extinction was temporarily averted, and in this ten-year simulation, you can finally live peacefully to the end...]

In the ninth year, for reasons unknown, the Luo Shen Clan's patriarch, Luo Tian Shen, unexpectedly perished. The Earthly Sovereign Elders of various factions within the clan fought fiercely for power, leading to the disintegration of the Luo Shen Clan. Luo Li was devastated by this, and you stayed by her side day and night, comforting her. Furthermore, as the son-in-law of the Luo Shen Clan, you secretly supported the faction close to you…

Under your strategic planning, this force quickly swept away other factions and reunified the Luo Shen Clan. With the situation settled, you voluntarily stepped back from the limelight, recommending Luo Li to become the new clan leader…

[At this point, Luo Li's heart was completely won over. The two of you have cultivated the Great Emperor's Inner Scripture together, and have finally mastered the Supreme Scroll...]

[Subsequently, your spiritual veins advanced to the Heavenly level, and your cultivation broke through to the Seventh Rank Supreme. A Seventh Rank Supreme at less than twenty years old is extremely rare, even within the entire Western Heaven Battle Palace. The Western Heaven Battle Emperor personally summoned you and bestowed upon you the cultivation method for the Battle Emperor's Dharma Body…]

Though you felt helpless, you could only accept it respectfully. Afterwards, when Consort Ling learned that you and Luo Li had mastered the Supreme Scroll of the Great Emperor's Inner Scripture, she immediately summoned you back to her palace and, under the pretext of "checking your cultivation," severely exploited you...

[In the tenth year, you successfully broke through to the Ninth Rank Supreme, achieving the Great Perfection of the War Emperor's Dharma Body. The Western Heaven War Emperor officially appointed you as a candidate for the War Palace Holy Son and bestowed upon you a great divine power—the Million Heaven-Sweeping Hand!]

[Subsequently, you will record the Supreme Scroll of the Great Emperor's Inner Classic, the Supreme-level Alchemy Inheritance, the Method of Cultivating the War Emperor's Dharma Body, and the Million Heaven-Grasping Hands into the inheritance jade slip.]

[This simulation ends——]

You can choose one of the following three items.

【I. Myriad Beast Spirit Fire (Heavenly Level)】

Second, Blood Demon Arm (Low-grade Divine Artifact)

[3. Your inheritance jade slip]
