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

Chapter 160 Heavenly Fire Resurrected, Nine-Star Dou Zong!
"Know yourself and know your enemy, and you will never be defeated..."

Lu Yu stared at the simulation results on the light screen and let out a long sigh of relief. With the rich experience accumulated from numerous simulations and his precognitive understanding of the plot, he had finally defeated Mu Chen, the chosen one.

Strictly speaking, defeating Mu Chen wasn't the most difficult thing. The real challenge lay in reversing the tragic fate of the Blood God Clan.

The key to making this happen lies with Luo Li.

Therefore, I can only make things difficult for Mu Chen and force my simulated self to work harder...

"Although the process was somewhat tortuous, the result was always good..."

"The Heaven-Reaching Myriad Beast Spirit Fire, the low-grade divine artifact Blood Demon Arm, the second volume of the Great Emperor's Inner Scripture, and the cultivation method for the Supreme stage..."

“They’re all good things…”

"Of the three items, my inheritance jade slip is naturally the most valuable. But in terms of usefulness, the Heaven-Reaching Myriad Beast Spirit Fire is currently the most useful to me. But the problem is..."

"A simulation of a Celestial Supreme-level power like the Western Heaven Battle Palace is extremely rare. If we don't choose it this time, who knows when we'll get another chance to simulate it..."

A glint of light flashed in Lu Yu's eyes. With the blessing of the Earth-grade spiritual vein, his cultivation before becoming a Dou Sheng was almost without any bottlenecks.

However, after reaching the Dou Sheng stage, the cultivation speed will decrease significantly. If you want to quickly improve your cultivation level at the Dou Sheng stage, improving the quality of your spiritual veins becomes especially important.

"The Supreme Scroll of the Great Emperor's Inner Classic..."

He muttered to himself, his fingertips unconsciously tapping the table. The most wonderful thing about this technique is that it can continuously improve the quality of spiritual veins, and what's even more rare is that it can also help one's cultivation partner improve together.

Thinking of Little Fairy Doctor and Xun'er, Lu Yu couldn't help but smile, silently thinking, "I choose three."

Before he finished speaking, a warm, smooth jade slip appeared out of thin air. Lu Yu placed it between his eyebrows, and a vast amount of information immediately flooded into his mind.

The profound operating methods of the Great Emperor's Inner Classic, the key to condensing the War Emperor's Dharma Body, the astonishing power of the Million Heaven-Grasping Hands... all kinds of inheritances unfold like a scroll.

What surprised him most was that the transmission of the Supreme Scroll of the Great Emperor's Inner Classic contained some unspeakable and enchanting scenes, as well as personal insights gained during dual cultivation, as if he had experienced them firsthand.

"This simulation was truly excellent value for money..."

……

Soon after,

As Lu Yu stepped out of the meditation room, Venerable Heavenly Fire arrived like a wisp of green smoke, sensing the soul fluctuations around Lu Yu that had not yet been fully contained.

A look of surprise and doubt appeared on his aged face as he exclaimed in astonishment, "It seems that the Pavilion Master's soul realm has improved again during this seclusion?"

Lu Yu's lips curled slightly, his five fingers casually clenching inside his sleeve as he calmly asked, "Senior, are you ready?"

"Today, I can begin refining pills for you, senior, and reshape your physical body!"

Upon hearing this, Venerable Heavenly Fire's illusory figure trembled slightly, and he said excitedly, "Everything is ready! Thank you for your help, Pavilion Master! I will never forget this life-saving grace!"

"Senior, you are serious."

Lu Yu nodded slightly, and with a flick of his sleeve, hundreds of medicinal herbs poured out of his storage ring like a galaxy, floating orderly before him. These were just the auxiliary ingredients; the Bone-Growing and Blood-Melting Pill, as a peak seventh-grade pill, was far more complicated to refine than ordinary people could imagine.

He gently raised his hand, and the three jade boxes opened, revealing the three main ingredients treasured within: the Evergreen Spirit Vine, shimmering with emerald light; the Blood Essence Demon Fruit, exuding crimson mist; and the Snow Bone Ginseng, radiating a bone-chilling cold.

Lu Yu closed his eyes and concentrated, the refining technique of the Bone-Growing and Blood-Melting Pill flowing through his mind like a clear spring, every detail firmly memorized...

"call……"

When he opened his eyes again, they were clear. With a flick of his sleeve, the Azure Phoenix Cauldron crashed to the ground, and a dazzling golden flame rose up, enveloping the cauldron.

"This alchemy attempt may trigger alchemical lightning."

Lu Yu turned to Venerable Tianhuo and instructed, "Please, senior, protect us outside."

"Rest assured, Pavilion Master!" Venerable Heavenly Fire solemnly replied, and just as he was about to leave, a green shadow suddenly appeared.

Venerable Feng sensed the commotion and appeared in the courtyard. Upon seeing the scene, he was surprised: "Young friend, are you about to start refining pills?"

"Exactly."

Lu Yu responded with a smile, and with a flick of his sleeve, several medicinal herbs disappeared into the cauldron like birds returning to their nests. Under the terrifyingly high temperature of the Floating Pagoda Fire, the herbs were rapidly refined into pure medicinal powder. The entire process was smooth and efficient, completed in less than a quarter of an hour.

Venerable Feng observed intently and couldn't help but exclaim, "The medicinal powder actually contains spiritual energy... Is young friend about to break through to the eighth rank?"

"Let's give it a try."

Lu Yu spoke calmly, but his hands never stopped moving. Several hours later, when all the auxiliary materials had been refined, his gaze finally turned to the three main ingredients.

Seeing this, Venerable Feng understood and stepped aside, standing shoulder to shoulder with Little Fairy Doctor and Zi Yan, who had come upon hearing the commotion. Little Fairy Doctor's eyes were calm and serene, while Zi Yan curiously stood on tiptoe. All three of them watched this exceptionally important alchemy process with bated breath.

Lu Yu flicked his finger, and the Evergreen Vine leaped into the medicine cauldron.

"laugh--"

The withered vines trembled violently in the raging flames, their surface glowing with an emerald-like fluorescence as they stubbornly resisted.

With a slight thought, Lu Yu's golden flames suddenly transformed into a ferocious fire dragon, and the temperature soared. Half an hour later, accompanied by a faint cracking sound, the withered vine was finally refined, completely transforming into a vibrant emerald liquid.

Lu Yu waved his hand lightly, and all the medicinal powders and liquids flowed into it like rivers flowing into the sea. The first step of fusion was completed perfectly, and an hour later, a lustrous, viscous substance was slowly circulating in the flames.

For the next period of time, Lu Yu was completely immersed in alchemy. Little Fairy Doctor would silently bring him pills to nourish his soul every day, while Zi Yan obediently stayed outside the courtyard, not even bothering to eat her favorite spiritual fruit.

Until noon on the tenth day—

"boom!"

A deafening thunderclap suddenly erupted, shaking the entire Holy Pill City. Countless gazes turned to the sky, where, amidst the chaotic silver thunderclouds, blue and red colors spread rapidly like splashed ink, eventually transforming into three-colored thunderbolts that intertwined in the sky, dyeing half the sky with magnificent colors!
"Three-colored lightning! It's the birth of an eighth-grade pill!"

"Judging from the location, it's from the outer realms. Could it be that some master is refining pills in a furnace?"

The city was immediately in an uproar, and many alchemists excitedly rushed towards the direction of Thundercloud.

Inside the courtyard, Lu Yu slowly finished his practice, gently wiping the fine sweat from his forehead. A satisfied smile curved his lips: "Refining an eighth-grade pill for the first time has been more mentally taxing than I imagined..."

Before he could finish speaking, the medicine cauldron suddenly trembled violently, and a beam of blood-red light burst out of the cauldron, attempting to escape into the sky!

"Want to go?"

Lu Yu chuckled, and a golden light flew out from his sleeve, transforming into a net that firmly enveloped the blood-red light. Within the net, a dark red pill spun rapidly, its surface shimmering with iridescent light, its pupils sparkling as if they were the eyes of a living being.

Even more astonishingly, the spiritual mist surrounding the pill condensed into a miniature blood dragon, baring its teeth at everyone.

Venerable Feng clapped his hands in praise: "The elixir has taken form, and its spiritual essence has arisen! This is indeed the mark of an eighth-grade elixir. Congratulations, young friend, from this day forward you are a true eighth-grade alchemist..."

Zi Yan, standing to the side, curiously reached out her little hand, wanting to touch the little dragon formed from the elixir, but was gently stopped by Little Fairy Doctor.

"It's just a fluke."

Lu Yu waved his hand and smiled, handing the pill to the eagerly watching Venerable Tianhuo. "You might succeed the first time, but you might not be so lucky the second time." He turned to the crowd and said, "Please wait a moment, everyone. I'm going to undergo a tribulation."

Before he finished speaking, black flames suddenly erupted around him, and with a light step, he soared straight into the sky!

"Young friend, wait! Dan Lei is dangerous..."

Venerable Feng's expression changed drastically. He was about to give chase when he saw that the three people present were all unmoved, which made him suspicious.

At that moment, a strange change occurred in the sky—

"Boom!"

Suddenly, the sky above changed color as a gigantic fiery hand, hundreds of feet long, tore through the clouds. The entire hand was ablaze with brilliant golden flames, and as its five fingers spread, they stirred up the surrounding energy, resembling a heaven-scorching hand that held sway over the heavens!

"Open the pulse!"

Lu Yuqing's shout was like a thunderclap from the heavens, and golden light simultaneously emanated from all 360 acupoints on his body. The giant palm responded, suddenly unleashing a terrifying suction force capable of swallowing the heavens and earth!
"Click——!!!"

The sky full of lightning was crushed into countless fragments of lightning by this giant hand!
A colossal serpent of the underworld swelled against the wind, rising with its momentum. Its head was as majestic as a mountain, and it opened its abyssal maw to devour the countless fragments of lightning. With each lightning bolt that entered the serpent's mouth, a mysterious lightning pattern appeared on its scales.

"Roar!"

The giant python let out a dragon's roar that shook the heavens, and dazzling black light shot out from its snake eyes. After devouring the last lightning tribulation, the python's body suddenly expanded to three times its original size, and the clanging sound of metal clashing between its scales rang out. The black flames wrapped around its body transformed into a tangible Xuanming battle armor!
A Dou Zun-level Different Flame!
Boom!

The Netherworld Demonic Fire transformed into a black waterfall, cascading down like a celestial river pouring into Lu Yu's body. A vast torrent of energy surged through his limbs and bones, causing them to gleam with a jade-like luster as they were washed by the energy.

The Wind Venerable in the courtyard stared in disbelief: "Strange Fire... autonomous breakthrough?"

The Little Fairy Doctor's lips curled slightly, her eyes reflecting the figure standing in mid-air, her gaze filled with wonder.

Zi Yan excitedly tugged at her sleeve and jumped up and down: "I knew Lu Yu was the best! I'm going to eat ten candied hawthorns to celebrate when he comes down!"

Above the sky, Lu Yu slowly opened his eyes, black flames swirling within them. The barrier of his Nine-Star Dou Zong realm shattered under the feedback of the strange fire energy, and a vast torrent of energy condensed around him into a deep black vortex.

He stepped through the air, creating ripples in the space beneath his feet. Residual lightning crackled around his clothes. His aura surged, finally stabilizing at the peak of the Nine-Star Dou Zong realm, just one step away from becoming a Dou Zun!
Venerable Feng suddenly took a deep breath and sighed to the two people beside him, "A nine-star Dou Zong and an eighth-grade alchemist at less than twenty years old... such talent is probably unmatched among the younger generation in Zhongzhou today!"

At this moment, Lu Yu descended from the sky, his aura already concealed, but the occasional black flames flickering in his eyes still sent chills down one's spine.

"I've kept you waiting for a long time."

Lu Yu smiled slightly and turned to Venerable Tianhuo, "Senior, it's time to reshape your physical body."

Upon hearing this, Venerable Wind stroked his beard and looked at Venerable Heavenly Fire. He had noticed this person earlier, but hadn't had a chance to ask.

At this moment, I couldn't help but ask curiously, "Who is this gentleman?"

Lu Yu's expression turned serious as he introduced, "This is Venerable Tianhuo, the one I mentioned to you before who reshaped his physical body. He is a five-star Dou Zun and a rare master of formations."

He then turned to Venerable Tianhuo and introduced him, "This is Venerable Feng of the Starfall Pavilion, a close friend of Senior Yao."

The soul of Venerable Heavenly Fire stroked his beard and smiled, "I have long heard of Venerable Wind's great name, and today I finally get to meet him."

Venerable Wind hurriedly returned the greeting: "So it's Senior Heavenly Fire, my apologies for my rudeness!"

Lu Yu interrupted their mutual flattery: "Let's get down to business first. Senior Tianhuo, please come with me to the quiet room."

"Good, good, good, important matters come first!" Venerable Tianhuo nodded repeatedly, his voice filled with barely suppressed excitement.

After the two entered the quiet room, Lu Yu gently placed the corpse of the Earth Demon Old Ghost on the stone platform and said solemnly, "Senior Tianhuo, the refining is about to begin. Are you ready?"

Venerable Heavenly Fire took a deep breath, his soul trembling slightly, and said in a deep voice, "I have waited for this day for hundreds of years, and I have long been fully prepared!"

Lu Yu flipped his hand and took out a jade bottle, from which purple blood slowly flowed. The astonishing energy fluctuations caused the space to tremble—it was the essence blood of the seventh-tier peak Purple Crystal Winged Lion King.

"go with!"

Lu Yu flicked his finger, and the purple essence blood was splashed all over the corpse. The moment the blood touched the body, it made a hissing sound, and the skin began to rot rapidly.

Venerable Heavenly Fire couldn't help but exclaim in amazement: "What domineering essence blood energy!"

Lu Yu gently raised his hand, and the corpse floated up. With a wave of his sleeve, golden flames surged forth, completely enveloping the skeleton. As the temperature rose, a strange scene unfolded: the purple blood slowly seeped into the corpse's interior, and the originally pale skin and muscles gradually regained their vitality.

After a long while, a dark purple skeleton floated in the air. At this moment, the purple color on the skeleton had penetrated deep into the bone marrow, emitting a faint fluorescence, just like an exquisite work of art.

"Young friend, is this done?" Venerable Heavenly Fire's eyes gleamed, his voice filled with anticipation.

Lu Yu smiled mysteriously and waved his hand, saying, "Senior, please wait. I have prepared a surprise for you."

He flipped his hand and took out a jade box. Inside the box lay a piece of crystal-clear hand bone, which looked like a work of art and exuded a faint aura of power.

"This is... the hand bone of a Battle Saint?!"

Venerable Tianhuo's expression changed drastically, and his voice rose eight octaves: "Where did you obtain such a treasure, young friend?"

Lu Yu smiled calmly: "I obtained it by chance, and it's just what you need for me, senior."

He then precisely severed the skeleton's right hand and reattached the Supreme Hand Bone. Although the sizes were slightly different, the two quickly fit together perfectly under the exquisite tempering of the Floating Fire.

Venerable Heavenly Fire was so excited that his soul trembled: "A Saint's hand bone... what an opportunity..."

Lu Yu smiled calmly and urged the Floating Pagoda Fire to continue forging. Soon after, the skeleton suddenly trembled, and the joint of the right hand was stained with a faint purple halo. Under the forging of the strange fire, it was completely fused.

"Senior Tianhuo!" Lu Yu shouted solemnly.

Venerable Heavenly Fire immediately took out the Bone-Melting Blood Pill and swallowed it, his voice resolute: "I am ready!"

Having said that, his figure instantly transformed into a stream of light and disappeared into the bones.

"Oh!"

The moment the soul entered the body, the bones trembled violently. Light gradually gathered in the empty eye sockets, and terrifying energy emanated from within the bones. Under the miraculous effects of the Bone-Growing and Blood-Melting Pill, flesh and blood began to grow miraculously on the surface of the bones.

"Senior, hang in there! The pain of this reconstruction is no small matter!"

Watching the rapidly writhing flesh and blood, Lu Yu let out a low shout, and golden flames suddenly surged forth. The newly formed flesh and blood were constantly burned and regenerated in the flames, and the muffled groans of the Heavenly Fire Venerable echoed in the quiet room.

After ten hours of tempering, Lu Yu's hand seals slowly changed, and the golden flames around his body gradually subsided.

The body lying quietly on the stone platform has taken shape, its skin shimmering with a warm, jade-like luster, and faint, mysterious energy fluctuations emanating from it.

"Next, we just need to wait for the senior to complete the final fusion with this body."

Lu Yu wiped the sweat from his forehead, his voice tinged with fatigue but unable to hide his joy.
