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

Chapter 142 Everything is ready, let's march into Demon Flame Valley!

"Excellent, excellent! This simulation has been very fruitful. Choosing the Luo Shen Clan has indeed yielded significant benefits..."

Lu Yu's eyes lit up as he looked at the three options in the simulation.

Immediately after a moment's thought, he thought to himself, "I'll pass on the low-grade divine artifact. The Heavenly Water Sword is a water-attribute divine artifact just from its name, which doesn't match my attribute. There's no need to choose it."

"As for the inheritance jade slip, there are five divine techniques inherited, one of the high-level Earth-rank Taixu Yin Yang Sword Manual, which, when cultivated to perfection, is comparable to a divine technique and is estimated to be a fighting skill of the same rank as the Emperor Seal Technique, which can also be considered a Heaven-rank fighting skill. There is also the Ten Thousand Poison Palm, which is equivalent to six Heaven-rank fighting skills and one high-level Earth-rank fighting skill."

"It's valuable, but it certainly can't compare to the Phoenix Nirvana Pill gifted by Emperor Yan..."

Lu Yu pondered in his heart that the Heavenly Phoenix Nirvana Pill could reshape one's foundation when breaking through to the Ninth Grade Supreme, greatly increasing the probability of breaking through to the Earthly Supreme. However, he was not quite sure how much this increase was.

However, he knew that in the vast world, if a Ninth-Rank Supreme wanted to break through to the Earthly Supreme, he needed to shatter the Supreme Sea, crystallize the liquid Supreme Spiritual Power, and completely integrate it into his physical body, transforming it from a unique entity into something omnipresent, making every piece of flesh equivalent to a Supreme Sea.

This process was extremely dangerous, and nearly half of the ninth-rank supreme beings perished because they could not withstand the erosion of the crystallized spiritual power.

The second is the spiritual tribulation baptism, which requires tempering the supreme Dharma body into a celestial Dharma form. Most of the remaining half of those attempting this trial perish at this stage.

The crystallization of spiritual energy and the manifestation of the Dharma of Heaven and Earth are the two major hallmarks of the Earthly Sovereign. The former grants the cultivator a near-immortal physical body, which can be reconstructed through crystalline spiritual energy even if the body is completely destroyed, although it takes a considerable amount of time; the latter allows the cultivator to mobilize the great power of heaven and earth, possessing boundless might.

"In this vast world, there are actually quite a few pills that can help a Ninth-Rank Supreme break through to the Earthly Supreme realm. The most common one is the Supreme Breakthrough Pill, which can help a Supreme expert crystallize liquid spiritual energy. However, after the transformation, it's hard to say whether they can withstand the erosion of the crystalline spiritual energy..."

"This Heavenly Phoenix Nirvana Pill contains the power of Nirvana. It might be able to reshape my physical body and save my life when I break through to the Earthly Sovereign realm. That's why it's called greatly increasing the probability of success. Once I pass the stage of spiritual energy crystallization, it's like having one foot in the door of the Earthly Sovereign realm. It's a priceless treasure!"

Lu Yu's eyes flashed with a sharp light, and his heart burned with excitement. He clearly remembered that both Xiao Yan from the lower plane and Mu Chen from the Great Thousand World had undergone a process of physical reshaping when breaking through to the Dou Di and Earth Supreme realms, so that they could withstand the impact of higher-level energy.

In other words, by choosing this Heavenly Phoenix Nirvana Pill, he had essentially obtained half a ticket to becoming a Dou Di.

"I'll choose this one. I can choose another divine technique later. This Supreme-grade Divine Pill, personally gifted by Emperor Yan, is probably the most top-tier Supreme Divine Pill. Its value is far greater than that of the Breakthrough Pill. It's extremely rare and hard to come by..."

Once he made up his mind, he chose the first option without hesitation.

In an instant, an ancient wooden box appeared in the void. The box was dark red all over, and a burning flame pattern was engraved on its surface. Upon closer inspection, the flame was actually transformed from a pill furnace, and above the furnace, a figure could be vaguely seen standing proudly.

The figure stood with his hands behind his back, his black hair flying, a heavy black ruler slung across his back. Though only a silhouette, he exuded an aura of majesty that commanded the heavens and earth to submit. He stood there quietly atop the alchemy furnace, as if the entire world lay at his feet.

"This is……"

Lu Yu's pupils contracted slightly; even with his composure, he couldn't help but be awestruck by this figure. That aura that surpassed heaven and earth could only be possessed by the strongest beings standing at the pinnacle of the Great Thousand Worlds.

"Heh, isn't this the future Yan-di?"

Lu Yu suddenly chuckled and shook his head, saying, "This kid is quite vain; he actually had his image engraved as the emblem of the Endless Fire Domain."

He reached out and gently stroked the flame patterns on the jade box, and suddenly felt a familiar energy fluctuation at his fingertips.

"The Serpent's Sealing Spell?"

Lu Yu raised an eyebrow, then understood: "It seems that I was cautious in the simulation, knowing to add a layer of seal to such a precious pill."

He tried to probe the strength of the seal and found it to be exceptionally powerful. Considering that he was also a supreme expert in his simulation, he realized that this seal would probably require the strength of a Dou Sheng to break.

"Alright."

Lu Yu nodded thoughtfully, took out a separate storage ring, put the wooden box inside, and thought to himself, "This thing is too high-level. I don't need it now anyway. I can open it after I break through to the Dou Sheng realm. If I lose it and some guy finds it, the Dou Qi Continent will probably change drastically."

"Adding another layer of Dou Sheng seal, Dou Sheng are rare in the Dou Qi Continent, they have their own prestige, and they probably wouldn't deliberately pick up a low-quality storage ring on the ground, so this is indeed safer."

Thinking of this, Lu Yu nodded, quite satisfied with how he acted in the simulation.

As expected of me, so cautious!
……

Soon after,

The stone door to the meditation room slowly opened, and Lu Yu stepped out. The illusory soul of Venerable Heavenly Fire was already waiting outside, its semi-transparent body floating in the air, its aged face carrying a hint of inquiry.

"What are your plans next?" Venerable Tianhuo stroked his long beard, his eyes filled with concern.

Lu Yu smiled slightly, a glint of light flashing in his eyes, and said, "Let's return to Canaan Academy first. This time, in the siege of Demon Flame Valley, we must eliminate it completely. I will gather all available people and lay a tight net, ensuring that not a single fish escapes."

He flicked his fingertips, and a wisp of golden flame danced in his palm: "The Demon Flame Valley has occupied the Black Corner Region for many years, possessing profound resources. We must not only deal with the powerful figures on the surface, but also guard against their hidden escape routes. Therefore..."

Venerable Tianhuo nodded in understanding and said, "Therefore, we need enough manpower to seal off all the key passages."

"Exactly."

Lu Yu extinguished the flames, a slight smile playing on his lips, and said, "My Spirit Treasure Pavilion has accumulated so much power; it's time to let everyone in the Black Corner Region witness it."

……

Three days later,

The inner courtyard of Canaan College.

Inside a quiet little courtyard,
Lu Yu sat at the stone table, and in front of him, the three women, Qing Lin, Zi Yan, and Xiao Yi Xian, were gathered together.

Lu Yu's expression turned serious, and he asked earnestly, "Qing Lin, tell me about your current cultivation level."

"Young Master, Qing Lin has already reached the peak of the Dou Wang realm..."

Seeing that the young master seemed somewhat displeased, Qinglin quickly raised her wrist, revealing the seven-colored snake coiled around it, and said, "Xiao Cai is already at the peak of the Dou Huang realm. Xiao Cai and I have absorbed all the magical beasts that the young master caught before..."

Lu Yu shook his head and said, "It's still too slow. It's a pity that there are too few sixth-order snake-type magical beasts in the Magical Beast Mountain Range and Black Corner Region. I'll think of a solution for you after some time."

As he spoke, he took out a jade bottle and an ancient scroll from his storage ring: "Inside are the Breaking Emperor Pill and a soul cultivation technique called the Soul-Slaying Sword Scripture. Take it and cultivate it well. You must break through to the Dou Huang level within half a month."

"Qinglin understands." The girl respectfully accepted it and nodded solemnly.

But then she hesitated and said, "Young Master, actually... Qinglin may not need the Breaking Emperor Pill."

"Oh?" Lu Yu frowned slightly.

Qinglin scratched her head sheepishly, then suddenly waved her hand, and ten enormous fifth-tier serpentine magical beasts appeared behind her. She explained, "Young Master, I've been studying insect-controlling techniques lately, and now I can control ten fifth-tier magical beasts simultaneously in battle. Four of them were caught for me by you, two were captured by Xiao Cai, and the remaining four..."

Her voice lowered: "I bred it myself." "You bred it yourself?" A look of surprise flashed in Lu Yu's eyes.

Qinglin continued to explain, "It's really hard to find magical beasts of the fifth rank or higher, so I came up with a plan. I had Xiaocai capture a few fourth-rank magical beasts, and then, through the bloodline link technique, they gained some of Xiaocai's talents. After these magical beasts advanced to the fifth rank by devouring lower-rank magical beasts, Xiaocai and I then absorbed their battle qi. This way, we don't have to go through the trouble of searching for high-rank magical beasts..."

Upon hearing this, Lu Yu remained silent for a moment before finally speaking: "You mean, you used Xiao Cai and the bloodline link technique to cultivate several low-end versions of the Seven-Colored Sky-Devouring Pythons, letting them grow on their own, and you only needed to harvest them periodically..."

"do you mean this?"

“That’s right.” Qinglin nodded obediently in response.

Lu Yu suddenly chuckled, a look of approval flashing in his eyes, and said, "That's a good idea. Since you already have your own cultivation plan, I won't have to worry about you too much in the future."

After saying that, he turned to look at the Little Fairy Doctor who was standing quietly to the side.

Before he could speak, Little Fairy Doctor gently shook her head, her fingertips flickering with dark blue and dark green flames, and slowly said, "With the help of Netherworld Poison Fire and Sea Heart Flame, I am confident in the battle of Demon Flame Valley, so there is no need to worry."

Lu Yu nodded in understanding, and finally turned his gaze to Zi Yan, who was enjoying her meal.

The little girl was happily eating a bunch of high-level pills she had brought back. When she noticed his gaze, she waved her hand dismissively, clearly not needing his attention.

Just then, ripples suddenly appeared in the courtyard. A graceful, colorful figure stepped through the air, her red dress as red as fire, her figure elegant and slender—it was none other than Cai Lin, whom we hadn't seen in a long time.

She lightly touched the ground with her jade-like feet, her beautiful eyes sweeping over everyone before finally settling on Lu Yu: "I'm not late, am I?"

Lu Yu glanced at her briefly, then stroked his chin and raised an eyebrow, saying, "You haven't even broken through to the second-star Dou Zong level yet?"

Upon hearing this, Cai Lin's expression froze. After sensing the powerful aura of a six-star Dou Zong on Lu Yu's body, she parted her lips as if to refute, but then swallowed her words back.

After a moment of contemplation, Lu Yu suddenly asked, "I remember you practice sword techniques and combat skills?"

“Exactly.” Cai Lin nodded slightly, her red skirt swaying gently in the wind.

Lu Yu smiled slightly, took out a warm jade slip, and said, "Coincidentally, I have a cultivation technique here that might suit you."

As he spoke, he had already entered the contents of the first volume of the "Nine Heavens Sword Primordial Spirit Chapter" before the Supreme Realm into it and handed it to Cai Lin.

Cai Lin took the jade slip with a hint of doubt. When her soul power swept over its contents, her graceful body suddenly froze, her red dress fluttered without wind, and an expression of disbelief appeared on her beautiful face.

"This...is this?" Her voice trembled slightly, a rare occurrence. The sword intent contained within the jade slip was vast and profound; with just a slight perception, the battle qi within her body surged like boiling water.

Lu Yu stood with his hands behind his back, a playful smile on his lips: "The cultivation technique I picked up on the way out, does it suit your taste?"

Cai Lin's slender fingers unconsciously tightened, the jade slip slightly warm in her palm. As a queen who ruled over a region, she had no doubt about her judgment. Although this cultivation technique seemed to be only a fragment, it was enough to make countless experts above the Dou Zong level fight tooth and nail for it.

With this cultivation technique, I fear I can reach the Dou Zun level within a few years.

"What is the price?" she asked, taking a deep breath and trying to remain calm.

"Ok?"

Lu Yu was taken aback at first, then chuckled and said, "Since you are my guard, you can't be too weak. Consider this scroll of cultivation technique a reward for your hard work these past few days."

Cai Lin remained silent for a long time, but she was unwilling to let go of the jade slip.

The things inside were simply too tempting for her.

She couldn't bring herself to refuse, but how could she possibly repay this employer who was also a benefactor of the snake people?
"I will remember this favor." A complex emotion flashed across her cold and beautiful face, but her voice remained clear and cold. "I will repay this favor in the future."

Lu Yu shook his head and chuckled. This stubborn nature was exactly like that of those aloof sword cultivators.

"Switch to a new cultivation technique as soon as possible. Set out for Demon Flame Valley in half a month," he instructed with a smile.

"clear."

As she turned to leave, her hand holding the jade slip tightened even more as she swayed her colorful red skirt.

……

Half a month later, in Demon Flame Valley.

This colossal structure, perched in the northern part of the Black Corner Region, sits within a vein of dark steel ore. The entire valley appears as if carved out of the mountain by a giant, its dark rock walls gleaming with a metallic sheen under the sunlight.

At the valley entrance, dozens of guards dressed in black and red stood imposingly, their sharp weapons gleaming coldly in the sunlight. Various factions, having come to visit, lined up in a long queue, undergoing rigorous questioning.

Suddenly, a whooshing sound came from the sky.

"Who goes there?!" the leading captain of the peak Douling guards shouted sharply, his long sword pointing straight at the sky.

However, no sooner had he finished speaking than a pillar of azure fire crashed down like divine punishment, instantly engulfing him. When the flames subsided, only a wisp of ashes remained, drifting away in the wind.

Lu Yu arrived through the air, standing with his hands behind his back on the clouds, his cyan robe fluttering in the fierce wind. He glanced indifferently at Wuya beside him, who immediately understood.

Wu Ya grinned maliciously and stepped forward, unleashing a terrifying pressure at the Dou Zong level that swept out like a tidal wave. His voice, like muffled thunder, echoed throughout the valley: "Lingbao Pavilion is handling official business; bystanders—"

"Get out of here within ten breaths!"

The shout was like a thunderclap, shaking the entire valley.

In an instant, the entire world fell silent.

The representatives of various forces queuing at the valley entrance were all horrified, some of the weaker ones collapsing to the ground. That battle spirit guard, reduced to ashes, was none other than the infamous "Blood Blade" of Demon Flame Valley!

"That...that's Elder Centipede of the Spirit Treasure Pavilion?!" An elder from a minor force in the Black Corner Region exclaimed, his voice trembling. "He actually dared to attack Demon Flame Valley directly?"

His companion tightly covered his mouth, yelling, "Shut up! Do you want to die? Run!"

The next moment, the protective formation of Demon Flame Valley was activated, and a dark red light curtain enveloped the entire valley like blood.

Just then, a cold voice came from inside the valley: "Who are you, my friend, to grace my Demon Flame Valley with your presence?"
