Chapter 215 First Meeting with the Dean, Heavenly Realm Soul!
"Damn, two old coins..."

Seeing this, Lu Yu cursed inwardly.

He never expected the outcome to be like this. The so-called ancient inheritance turned out to be a carefully laid trap for possession, with both ancient giants harboring ulterior motives.

After calming down, he carefully weighed the three options:

Although the Supreme Pill can help people break through to the Supreme Realm, his current Dou Zun cultivation is not yet perfect, so he doesn't need it for the time being; and although the Heart Demon Seed Thunder Technique is extremely powerful, it has already been sealed with a fatal trap by the Heart Demon Thunder Emperor, so rashly cultivating it would be tantamount to courting death.

"In this light, the only safe option is the Nine-Turn Ice Purification Pill."

With a thought, Lu Yu made a decision. As the choice was made, a pill, crystal clear like jade and radiating pure spiritual energy, appeared out of thin air and hung quietly in front of him.

"The Nine-Bearded Blood Ginseng Pill strengthens the foundation of the physical body, the Heavenly Spirit Pill invigorates the source of fighting spirit, and with this Nine-Turn Ice Purification Pill... the pills needed to break through the Lesser Three Tribulations of the Supreme Realm are finally complete."

Lu Yu reached out and took the pill, a sharp glint flashing in his eyes.

He knew that his soul realm had reached the peak of the Spirit Realm and could not advance any further, while his physical body and battle qi cultivation had not yet reached the peak of the Battle Venerable realm, and he had not yet reached the point of taking the Nine-Bearded Blood Ginseng Pill and the Heavenly Spirit Pill.

However, the Dou Qi Continent is not the Great Thousand World, and the path of cultivation does not necessarily require strictly following the supreme path of the Great Thousand World, which involves gradual breakthroughs in the three aspects of "physical body, spiritual power, and divine soul".

In his view, it is acceptable to prioritize overcoming any of the difficulties, depending on one's own circumstances and opportunities.

"In that case, let the Soul Realm take the lead in taking that step!"

With this in mind, he no longer hesitated and swallowed the Nine-Turn Ice-Cleansing Pill. The pill melted instantly upon entering his mouth, transforming into a cool yet vast and boundless stream of pure energy that surged into the depths of his mind like a bursting dam!
The soul power, which had already reached a saturation point, began to tremble violently under the intense impact and nourishment of this exclusive medicinal power. The entire soul ocean seemed to be undergoing a world-shaking transformation, and the essence of the soul was frantically climbing to a higher level!
Boom!

In an instant, boundless black soul flames rose from the depths of his mind, instantly engulfing the entire consciousness space! These flames did not burn external objects, but rather frantically forged and tempered his own soul essence.

Amidst the surging flames, a black longsword formed from pure soul power suddenly materialized, its blade wreathed in destructive flames—a manifestation of the highest level of the Soul-Slaying Sword Scripture—the "Soul-Slaying Sword"!
However, the next moment——

"Crack!"

With a crisp sound, countless fine cracks appeared on the sword! This Soul-Slaying Sword, which had gathered most of Lu Yu's soul power, could not withstand the impact of the enormous medicinal power and shattered with a crash!
The backlash from the shattered sword surged like a tidal wave, and Lu Yu's soul form instantly became blurred and unstable, almost collapsing.

At this critical moment, he stabilized his collapsing origin with the Heavenly Fire Forging God Technique. The shattered black flames and sword fragments did not dissipate, but instead, guided by the technique, they converged again like rivers flowing into the sea!

Flames intertwined, fused, and reshaped with fragments of the sword... Finally, a more solid soul body, radiating vast majesty, slowly condensed and took shape. Its appearance was exactly the same as Lu Yu's original body, but its eyes contained a profound light that pierced through the void!
At this moment, a vast soul pressure naturally spread out. Although Lu Yu tried his best to suppress it, the unique aura of the Heavenly Realm soul could not be completely concealed!

Celestial Soul, complete!

"That's it..."

With a faint smile on his lips, Lu Yu slowly opened his eyes, quietly experiencing the profound feeling brought by the Heavenly Realm soul. The perception and control over the energy of heaven and earth was far beyond what he could have achieved in the Spirit Realm.

Several days later, after his soul realm had completely stabilized, Lu Yu finally got up and left the meditation room. He found Little Fairy Doctor and Cai Lin talking in a secluded courtyard.

"I need to use the Void Thunder Pool on Dragon Island to cultivate for a period of time in order to raise my Dou Qi cultivation to the peak of Dou Zun as soon as possible."

Lu Yu explained the situation to the two women, and then continued, "Although this place is good, the Lingbao Pavilion cannot be left unattended. You two go back first, and I will return immediately after I finish my seclusion here."

Upon hearing this, Little Fairy Doctor nodded gently and said softly, "You can cultivate here without worry. We will take care of the affairs of the pavilion."

She knew Lu Yu's pursuit of strength and understood that Lingbao Pavilion needed someone to take charge.

Although Cai Lin didn't say much, she simply nodded slightly, but her clear, cold eyes revealed understanding and support.

They all knew that the Void Thunder Pool was a rare opportunity for Lu Yu.

After making the arrangements, Lu Yu no longer hesitated and moved towards the main hall deep within Dragon Island.

—————————————————————

Soon after,

In the pitch-black void, a massive black dragon swept past like lightning, its strange fluctuations constantly resisting the spatial tearing forces coming from all directions.

"As expected of the Ancient Dragons of the Void, only they can move so freely in this void space."

On the back of the dragon, Lu Yu gazed at the rapidly receding void on both sides, and couldn't help but marvel. This void space was fraught with danger. Not only did space collapse frequently, but the omnipresent violent tearing force was enough to rip ordinary Dou Zun apart. Without special methods, it would be extremely difficult to travel here for long.

"Young friend Lu Yu, the Void Thunder Pool is not far ahead."

As they moved, the black dragon spoke in human language, its voice booming like a bell; it was none other than Hei Qing.

Lu Yu nodded slightly, a hint of anticipation flashing in his eyes.

The black giant tail suddenly swung in the void, and its massive body shot out like lightning, disappearing into the end of the void with a dazzling light.

The howling wind swept past his ears. Lu Yu squinted and suddenly saw a shimmering silver light faintly emerging at the end of the void. An unusually violent energy fluctuation was spreading from afar.

"Are we almost there...?"

As it drew closer, the silver light rapidly expanded, and a deafening thunderous roar resounded, shaking the very soul even from a great distance.

When the dragon finally stopped, Lu Yu stood on its head, gazing at the scene before him, his eyes filled with awe.

Before him stretched a vast, boundless silver "lake," thousands of feet long and wide, its waves magnificent. However, the water flowing within this lake was not clear water, but rather liquid energy formed from dazzling, blinding lightning—this was a true Thunder Pool condensed from the power of thunder!
Standing at the edge of the Thunder Pool, the booming thunder seemed to pour down from the heavens, making one's blood surge. Before this immense power of heaven and earth, the human form appeared so insignificant.

"Such intense lightning power..."

Lu Yu took a deep breath, his eyes burning even more intensely.

"This is it, young friend Lu Yu..."

The giant dragon that Hei Qing had transformed into said in a deep voice, "I will be waiting outside. You can call me after you finish your cultivation. Also, regarding the dean of Canaan Academy, Mang Tianchi, the fourth elder of my Dragon Island had already made contact with him when he entered the Thunder Pool some time ago."

At this point, Hei Qing's tone carried a hint of helplessness: "However, that dean seems to have a deep prejudice against our race, and he runs away as soon as he sees us. If you encounter him in the Thunder Pool, you can tell him that Dragon Island has given up on hunting him down, and there is no need for him to hide anymore."

Lu Yu nodded upon hearing this: "This junior understands."

Having finished explaining, Lu Yu didn't hesitate any longer. With a swift movement, he transformed into a streak of light and shot into the vast Thunder Pool.

Rumble!
The moment he rushed into the pool of lightning, countless bolts of lightning surged out like enraged silver snakes, bombarding him from all directions.

Lu Yu snorted coldly, and with a slight thought, a layer of purplish-gold flames rose from his body, enveloping him—it was the Floating Pagoda Fire! The violent lightning bolts erupted with a series of low, muffled sounds the moment they came into contact with the Floating Pagoda Fire, and then quickly vanished like ice and snow meeting the sun.

Although the outer lightning was strong, it still couldn't penetrate the Floating Pagoda Fire, which contained destructive power. This was precisely the source of Lu Yu's confidence in venturing into the Thunder Pool alone. After initially adapting, Lu Yu sat cross-legged, carefully sensing the concentration of lightning power around him. After a slight hesitation, he got up and stepped into the depths of the Thunder Pool.

Several hours later, he finally stopped. The power of lightning here had become extremely dense, the silver lightning was almost solidified, and the oppressive aura in the air was becoming more and more obvious, making people's hearts tremble.

"That's about enough, let's stop here."

Lu Yu pondered for a moment, then sat down cross-legged. With a thought, a nine-story black-purple pagoda exuding an ancient aura appeared above his head, slowly rotating—it was the Floating Pagoda!
"Nine Heavens Thunder Summoning Technique, activate!"

As he circulated his cultivation technique, lightning blazed brightly around him, generating a powerful suction force that actively drew in the surrounding immense lightning power. The raging lightning, after initial refinement by the Floating Pagoda, transformed into a purer and gentler energy, surging into Lu Yu's body like a tidal wave.

With this double blessing, his cultivation speed suddenly skyrocketed!

----------------------

During cultivation, time passes silently.

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

shhhhhh!
Within the Thunder Pool, countless silver lightning bolts, like enraged silver serpents, frantically crashed against the floating purplish-black pagoda from all directions.

However, whenever lightning strikes the tower, it is drawn and refined by an invisible force, eventually transforming into a torrent of pure energy that pours down.

Beneath the pagoda, Lu Yu sat cross-legged, his body absorbing boundless energy like a bottomless pit. Above his head, a hundred-foot-tall vortex of lightning spun rapidly, emitting a deafening roar and forcibly drawing in lightning power from even further away.

Boom boom boom!
This frenzied devouring continued for an unknown period of time before the enormous vortex of lightning finally began to gradually weaken.

The vortex shrank until it abruptly stopped and completely dissipated. At the same time, the violent lightning that had been swirling around Lu Yu's body also crackled and popped, disappearing beneath his skin.

As the vortex and lightning dissipated, Lu Yu's tightly closed eyes trembled slightly, and then he suddenly opened them!

boom!
The instant his eyes opened, two enormous bolts of lightning, seemingly solid, shot out from them like roaring thunder dragons, instantly tearing through layers of lightning curtains and plunging into the depths of the lightning pool before slowly dissipating.

An aura several times stronger than before slowly emanated from his body.

Seven Star Dou Zun!

"What a thunderous treasure land..."

As Lu Yu felt the surging power within him, a flash of surprise crossed his eyes, and he couldn't help but murmur his admiration.

Only then did he realize how hard his life had been before; the energy concentration in Tianmu Mountain was nothing compared to that!
No wonder the cultivation speed of people in the Great Thousand World far exceeds that of people in lower planes. Such supreme-level cultivation treasures are not uncommon in the Great Thousand World, even if they are not everywhere.

“Cultivating here has increased my speed by at least four or five times. I broke through to the first star in just half a month. My previous estimate of two months was too conservative.”

"They underestimated not only the energy concentration of this Void Thunder Pool, but also the terrifying efficiency with which the Eight Divine Veins absorb and refine energy..."

A glint of light flashed in Lu Yu's eyes, but after carefully sensing his surroundings, his brows furrowed slightly.

"The intensity of the lightning here seems to be insufficient for a Seven-Star Dou Zun."

He muttered to himself that the feeling of fullness he had just experienced after breaking through was rapidly fading, and his body instinctively craved more powerful energy to consolidate his realm and continue to improve.

After a brief moment of rest, he got up without hesitation and headed deeper into the Thunder Pool where the energy was even more violent.

After venturing some distance, Lu Yu finally selected a new training spot.

The lightning here was no longer simply silver; it was now interspersed with wisps of dark purple electric snakes, which emitted a destructive aura that stung the skin as they moved, and the energy concentration was several times stronger than that of the surrounding area.

Just as he was about to sit cross-legged, drawing upon this even more violent thunderous energy—

A hand suddenly slapped his shoulder from behind! At the same time, a deliberately lowered voice rang in his ear:

"Kid, are there any members of the Ancient Void Dragon Clan still keeping watch outside?"

Lu Yu's heart skipped a beat, and his fighting spirit almost instinctively began to circulate and counterattack. He turned his head abruptly and saw an old man who had somehow gotten close to him from behind.

The old man's hair and beard were all sticking up, and his robe sleeves were charred and torn in many places, making him look quite disheveled. However, his eyes were gleaming with sharp light as he rapidly and warily scanned the surging lightning around him, as if he were trying to avoid something.

If it's not Mang Tianchi, the long-lost dean of Canaan Academy, then who is it?
"Dean?"

"What dean? You know me?" Mang Tianchi's eyes narrowed, his vigilance deepening.

"I am Lu Yu, a junior, and I was once a student in the inner academy of Canaan Academy."

Lu Yu cupped his hands and said, "Dean, there's no need to hide anymore. The Ancient Dragon Clan will no longer pursue the matter of you using the Thunder Pool for cultivation."

"Hmph, easy for you to say. Do you think those snakes would be so kind?" Mang Tianchi looked unconvinced.

Seeing this, Lu Yu had a thought, and a crimson longsword flashed into his hand, its blade radiating a scorching aura: "Dean, please look at this sword. This is the Meteor God Sword, forged by me using the Meteor God Black Iron that you left behind at the academy. I was not only a student of the academy, but I also made great contributions to the academy, helping it suppress the Meteor Heart Flame."

Mang Tianchi sensed the familiar aura of the Fallen God's Profound Iron on the sword, and his expression softened slightly, but doubt still lingered in his eyes: "You really are a student of my academy? This sword is genuine, but I never expected that the piece of Fallen Heart Flame companion that I left for the academy would end up in your possession..."

He stroked his chin, looked Lu Yu up and down, and said with a hint of reminiscence, "That piece of Fallen God Black Iron was something I obtained from the bottom of the magma. It originated from the same source as the Fallen Heart Flame, and ordinary people simply cannot control it. You were able to forge it into a weapon and even helped the academy suppress that stubborn strange fire. You did a great thing."

At this point, his gaze toward Lu Yu became less wary and more appreciative.

Seeing this, Lu Yu breathed a sigh of relief and then said with a smile, "If the dean still doesn't believe me, you can come with me to see Senior Hei Qing, who is guarding outside, and question him about this matter face to face."

Mang Tianchi pondered for a moment, his powerful soul force quietly spreading outwards, instantly sensing the aura of an eight-star Dou Zun belonging to Hei Qing outside the Thunder Pool. He curled his lips, revealing a hint of composure befitting a powerful figure: "Hmph, a mere eight-star Dou Zun level dragon can't stir up any trouble. Fine! I'll trust you this once and accompany you on this journey."

He waved his hand generously, appearing quite cheerful: "If what you say is true, and you've saved me from this trouble of hiding and running, then I'll consider it a favor I owe you!"

Upon hearing this, Lu Yu smiled and nodded, taking the initiative to lead the way, and Mang Tianchi immediately followed.

The two quickly left the Thunder Pool and confronted Hei Qing. Only then did Mang Tianchi confirm that Lu Yu's words were true. He learned that it was Lu Yu who pleaded for him, which is why the Ancient Dragon Clan stopped pursuing the matter.

The usually carefree elder of the Lei clan couldn't help but show a hint of embarrassment, patting Lu Yu on the shoulder and saying:
"Ahem... I see. Kid, I owe you a favor this time! If you encounter any trouble in Zhongzhou in the future, just mention my name!"

"Dean, you're too kind. I'm quite accomplished these days..."

Before Lu Yu could finish speaking, a communication jade pendant at his waist suddenly shattered with a "crack"!
A rapid message flooded his mind; it contained only a few short numbers, yet it caused his expression to change drastically:
Lingbao Pavilion is in danger, return immediately!
