Chapter 153 Two-Colored Pill Lightning? The Opportunity for the Evolution of a Different Flame!

A few days later,

In the center of the Fenglei Mountain Range, a majestic and precipitous peak stands tall. This mountain is extremely high, and from the foot of the mountain, one cannot see its end at all. The upper part of the mountain is completely shrouded in dark blue thunderclouds.

Blinding flashes of lightning occasionally streaked through the thick clouds, and from a distance, the entire mountain peak appeared to be entangled by countless bolts of lightning, a magnificent sight that took one's breath away.

This is where the East Pavilion of Fenglei Pavilion is located—Leishan.

At this moment, atop Thunder Mountain, a vast silver plaza gleamed in the sunlight. Dozens of disciples of the Wind and Thunder Pavilion, clad in silver robes, sat cross-legged, cultivating within the plaza.

The most eye-catching feature was the towering silver pagoda in the center of the plaza, hundreds of feet tall, its body crackling with lightning and its spire piercing the clouds, shrouded in mystery. The surrounding, well-arranged buildings served as the residences of the Wind and Thunder Pavilion disciples.

“Master Lu, that is the Thunder Dragon Cauldron that I specially commissioned to be made in order to refine the Thunder Origin Pill.”

Lei Zunzhe pointed to a protruding platform on the mountaintop, where a silver-white cauldron was placed, its body carved with lifelike thunder dragon patterns.

"The thunder-attribute energy of heaven and earth is most concentrated at the top of Thunder Mountain. Refining a seventh-grade peak Thunder Origin Pill here will probably attract even stronger pill thunder."

Lei Zun Zhe stroked his beard and smiled, continuing, "But it's alright. I've already set up a fire chamber at the foot of the mountain. Together with this Thunder Dragon Cauldron, it should greatly increase your chances of success."

Lu Yu looked up at the rolling thunderclouds in the sky, his eyes flashing with a sharp light, and shook his head, saying, "No need for trouble, let's start the furnace here. I have my own way of dealing with the pill thunder."

Venerable Lei frowned slightly, about to say something. But then he thought that with him present, he could provide timely assistance even if something went wrong, so he nodded and said, "In that case, I will have my disciples withdraw. However..."

He hesitated slightly, "Several alchemists in the pavilion have heard that Master is going to refine the Thunder Origin Pill and they all want to come and observe. I wonder..."

"It's alright." Lu Yu smiled calmly.

Before long, on the silver plaza atop Leishan Mountain, Lu Yu sat cross-legged, carefully adjusting his current state.

On the high platform in front of him were eight rare lightning-attribute medicinal herbs, each wrapped with fine arcs of lightning, emitting astonishing energy fluctuations.

On the viewing platform on the east side of the square, Venerable Lei stood with his hands behind his back, flanked by Feng Qing'er, Little Fairy Doctor, and others. Several elderly men dressed in alchemist robes were also conversing in hushed tones, glancing towards the arena from time to time, their eyes filled with anticipation.

"Master, is this person truly capable of refining peak-grade seventh-rank pills?"

A hint of doubt flashed in Feng Qing'er's purplish-brown eyes as she questioned, "Judging from his age..."

"Qing'er, watch your words!"

Lei Zunzhe's face darkened, and his voice suddenly became stern as he rebuked, "In this Dou Qi Continent, how can one judge a person's true cultivation level by their appearance? Countless senior masters have reversed the aging process and become young again. Your reckless words are truly unbecoming of your character."

Feng Qing'er blushed slightly after being scolded, but still pursed her lips defiantly. Just as she was about to speak again, a strange fluctuation suddenly rippled through the room.

Lu Yu slowly opened his eyes, his hands forming a profound hand seal. In an instant, a dazzling golden flame rose from his palm, within which countless tiny runes could be faintly seen flowing, exuding an ancient and mysterious aura.

"This is... a strange fire?"

On the viewing platform, a white-haired seventh-grade alchemist suddenly stood up, his old eyes wide open, and couldn't help but exclaim in surprise.

"Master Bai, are you sure you're not mistaken? That really is a strange fire?"

Upon hearing this, another sixth-grade alchemist beside him couldn't help but ask a question in return.

"Nonsense! I've been refining pills for decades, and I've seen more of the world than you've ever walked the roads. How could I not recognize this strange fire?"

The seventh-grade alchemist known as "Master Bai" widened his eyes and couldn't help but retort.

The sixth-grade alchemist frowned and questioned, "But the golden flames recorded on the Strange Flame Ranking are either the fourth-ranked Golden Emperor Burning Heaven Flame or the seventh-ranked Nine Nether Golden Ancestral Flame. Even a Dou Zun expert would find it difficult to subdue these two strange flames, let alone a Dou Zong..."

Master Bai snorted coldly, about to retort, when a sudden change occurred in the arena. The golden flame suddenly rose up, transforming into a golden fire dragon that coiled and emitted an ancient and terrifying pressure.

The viewing platform fell completely silent.

Just as everyone was in shock, Lu Yu suddenly waved his sleeve and gently pushed the Thunder Dragon Cauldron aside.

Instead, a jade-green, ancient-style medicine cauldron appeared out of nowhere. The cauldron was carved with lifelike blue phoenix patterns, and faintly visible rainbow-colored light flowed around it.

"This is……"

Lei Zunzhe's pupils contracted sharply; with his keen eyesight, he could naturally see that this medicine cauldron was extraordinary. The Thunder Dragon Cauldron, which he had painstakingly collected materials to forge, was already at the peak of the seventh rank, just one step away from the eighth rank.

But the aura emanating from this cyan medicine cauldron seemed even more extraordinary than his Thunder Dragon Cauldron.

"Hmm, I've never seen this medicine cauldron before. It's unlike the mainstream medicine cauldrons on the continent. Could it be an ancient cauldron that came from some ancient ruins..."

Master Bai let out a soft exclamation, his cloudy old eyes flashing with a sharp light, and he stroked his beard as he spoke.

Upon hearing this, a glint flashed in Lei Zun Zhe's eyes, and he immediately felt reassured.

The fact that this Master Lu could casually produce such an ancient medicine cauldron, and possess a mysterious and extraordinary fire, suggested that his background was likely even more astonishing than he had imagined. No wonder he dared to refine pills atop Thunder Mountain; it turned out he had such profound knowledge and experience.

Perhaps this person really is some reclusive old monster.

Lu Yu seemed oblivious to the reactions of the crowd. He stared intently at the medicine cauldron, flicked his finger, and the Floating Pagoda Fire darted into the Azure Phoenix Cauldron like a nimble snake, instantly transforming into a raging inferno. The nine fire ports of the medicine cauldron opened and closed rhythmically, spewing out jets of scorching flames.

"First, melt the Thunderfire Branch."

Gazing at the churning golden flames within the cauldron, Lu Yu's expression turned solemn. Although his soul power had reached the half-step Spirit Realm, and he had the Azure Phoenix Cauldron and the Floating Pagoda Fire to assist him, this was, after all, his first time refining a peak seventh-grade pill, and he could not afford to be careless in the slightest.

With a flick of his sleeve, the green and red lightning branch on the high platform flew into the air and landed precisely in the medicine cauldron.

As soon as the medicinal herbs were placed into the cauldron, a clear and melodious phoenix cry resounded through the sky, and the golden fire dragon formed from the Floating Pagoda Fire opened its mouth and swallowed them whole.

Half an hour later, the golden fire dragon suddenly shuddered, opened its huge mouth, and spat out a bluish-red liquid that emitted a strong medicinal fragrance.

Lu Yu remained calm, continuing to add precious medicinal herbs one by one into the cauldron. Under the tempering of the Floating Fire, these herbs gradually transformed into essential substances, some in powder form, some in liquid form, and some in solid form…

"This master's control over the strange fire is simply divine, and the refining speed is so fast..." A sixth-grade alchemist couldn't help but exclaim in admiration.

"Hmph, it's just relying on the power of the strange fire. If I also had a strange fire..." another sixth-grade alchemist said sourly.

"madness!"

Master Bai shouted sternly, "You frogs in a well, you only see the power of the strange fire, but you can't see that this master's fire control technique has reached a state of perfection!"

Master Bai stared intently at the scene, unable to contain his admiration: "Have you noticed that the extraction time for each medicinal herb is exactly the same? The flame temperature changes according to the characteristics of the herbs? What's even more remarkable is that the essence of all the herbs retains its most perfect activity..."

Feng Qing'er stood to the side, a flicker of doubt crossing her beautiful purplish-brown eyes. Looking at the focused figure in the arena, and recalling her earlier skepticism, she couldn't help but wonder: Had she truly misjudged him?

Just then, Lu Yu suddenly formed hand seals, and the essence of all the medicinal herbs within the cauldron began to slowly converge. Golden flames transformed into a fine net of fire, gently enveloping the various medicinal liquids, beginning the most crucial fusion stage…

This process is the most difficult, requiring extreme patience and control, as the fusion of every bit of medicinal power must be just right.

Lu Yu carefully sensed the changes in the medicinal power within the cauldron. According to his estimation, this fusion stage alone would probably take several days.

Time flew by like water, and nine days had passed in the blink of an eye. "Pfft..."

A soft, gentle sound suddenly emanated from within the medicine cauldron. Lu Yu's gaze sharpened as he saw a viscous, multicolored liquid slowly taking shape within the golden flames, emanating a rich medicinal aroma that instantly filled the entire plaza.

"We've finally completed the initial integration."

Lu Yu let out a soft sigh of relief, fine beads of sweat already forming on his forehead. He said with a sigh of relief, "Refining a peak seventh-grade pill is indeed several times more complicated than I imagined."

Then, he changed the hand seals, and the golden fire dragon immediately increased its circling speed, beginning the final condensation process.

Under the tempering of the flames, the liquid medicine gradually shrank and condensed, eventually transforming into a silver pill embryo the size of a longan. Although the surface was still uneven, Lu Yu could clearly feel the immense medicinal power contained within.

"The core has been condensed; the next step is to nurture it."

Lu Yu muttered to himself. Although this final step didn't significantly affect the efficacy of the medicine, he, being a perfectionist, still controlled the golden flames to gradually weaken, allowing the gentle heat to slowly penetrate the embryonic form of the pill for final nurturing.

Soon after,

At noon, with a crisp pop, the lightning-attribute energy of the entire Thunder Mountain suddenly fluctuated violently.

On the viewing platform, Lei Zunzhe, who was resting with his eyes closed, suddenly opened them, his sharp gaze fixed on the direction of the medicine cauldron.

There, a refreshing fragrance of cinnamon slowly wafted out, invigorating all who smelled it.

"Boom!"

Almost simultaneously, the once clear sky suddenly became overcast, with thick, dark clouds swirling and thunder roaring through the heavens. The terrifying pressure of the heavens and earth sent a chill down the spines of everyone present.

"Danlei?! It's actually been successfully refined?!"

An uproar erupted on the viewing platform, and all the alchemists stood up excitedly.

Beside Venerable Lei, Feng Qing'er looked up at the sky, her delicate body trembling slightly beneath her green robes. Her beautiful purplish-brown eyes were filled with shock and disbelief.

She never expected that this guy, who looked to be about the same age as her, would actually complete the refining of a peak seventh-grade pill.

On the high platform in the center of the square, Lu Yu slowly stood up and gazed at the vast thunderclouds above his head.

With a flick of his sleeve, a one-armed earth demon puppet, its entire body gleaming with silver light, appeared beside him.

This time, he did not use the array inscribed inside the cauldron to suppress the energy fluctuations of the pills.

The reason is this: the reason for using the medicine cauldron to suppress it before was simply because the tribulation was troublesome. Now that there is the Earth Demon Puppet, it is a good opportunity to use the pill lightning to temper the Earth Demon Puppet and make it advance further. This is obviously the choice to maximize benefits.

"boom!"

Above the sky, black thunderclouds surged and condensed, eventually transforming into a vast sea of ​​lightning before the astonished eyes of the crowd.

However, amidst the intertwining and flashing of countless bolts of lightning, a strange silver light gradually emerged from the originally pitch-black lightning. That silver light appeared and disappeared, yet it caused the oppressive power of the entire thundercloud to suddenly increase several times over.

"A two-colored Dan Lei?!"

Lei Zun Zhe on the viewing platform suddenly stood up, his eyes filled with horror.

"It's not two-color, it's still a little short, it should be considered half-step eighth rank!"

At this moment, Master Bai suddenly pointed and spoke.

Everyone looked in the direction of the sound and saw the clouds churning in the sky. Amidst countless shocked gazes, the thunderclouds displayed two colors. Although black still dominated, a faint trace of silver was clearly mixed in.

Although the silver hue was faint, it stood out dazzlingly against the dark thunderclouds.

"It's probably the excessively dense lightning energy around Thunder Mountain that amplified this pill lightning..."

Master Bai's expression turned solemn, and he said in a deep voice, "Sect Master, it seems we need your help. With the strength of the puppet beside Master Lu, I'm afraid it will be difficult to withstand such a fierce pill lightning."

Lei Zun Zhe's expression turned solemn. He nodded and was about to make a move when Lu Yu said loudly, "Pavilion Master Lei, there is no need to make a move. I have my own way of dealing with this."

Lei Zun Zhe frowned slightly, and slowly lowered his hand that had been raised halfway in the air. After a moment of contemplation, he solemnly said, "Since Master is confident, I will certainly grant your request. However, if there are any unforeseen circumstances, I will immediately lend a helping hand."

He thought to himself: Although Lu Yu declined to help, he had entrusted him with this alchemy task.

If this alchemy master were to suffer any mishap under the pill lightning, and word got out that he, the Thunder Venerable, couldn't even protect an alchemist, who would dare to refine pills for him in the future?

"Master, this..." Master Bai hesitated, his aged face filled with worry.

Lei Zun Zhe shook his head slightly and said in a deep voice, "Since this Master Lu dares to face Dan Lei directly, he must have something to rely on. Let's just wait and see."

Even so, Venerable Lei's right hand had already quietly formed a hand seal, and an invisible energy barrier silently formed around the plaza. This was his unique "Wind and Thunder Barrier," which, once activated, could instantly envelop someone, both to trap enemies and to protect people.

On the viewing platform, Feng Qing'er bit her red lips tightly, her slender fingers unconsciously clenching the hem of her dress. Her beautiful purplish-brown eyes were filled with complex emotions, both shocked by Lu Yu's boldness and secretly hoping that he could create a miracle.

"This guy……"

Zi Yan stopped chewing the candied fruit, her purple eyes flashing with an unusual light, and muttered, "It's always so unexpected."

Little Fairy Doctor stood quietly in place, her plain white dress fluttering gently in the wind. She appeared calm, but her slightly trembling fingertips betrayed her inner tension.

As one of the people who knows Lu Yu best, she understands that he would never do anything without being sure of success, but she still can't help but worry about the terrifying Dan Lei.

At this moment, in the center of the square, Lu Yu stood proudly on the high platform, completely unaware of the thoughts of the people on the viewing platform.

He stared at the thunder above his head, his deep eyes flashing with a sharp light, his slender body trembling slightly, not from fear, but from excitement!
Because, the instant that silver lightning appeared, the Netherworld Demonic Fire that had been dormant within him suddenly surged violently.

This strange fire, originating from the Netherworld Demonic Lightning, now exuded a strong desire to devour, as if it had encountered an unparalleled delicacy and was restless.

This situation was all too familiar to Lu Yu!

This was exactly how it manifested when the Earth Core Flame devoured the Green Lotus Earth Core Fire Lotus Platform!

In other words, this bolt of lightning from the sky may very well help the Netherworld Heart Demon Fire advance even further!
"interesting……"

Lu Yu's lips curled up slightly, and a glint of light flashed in his eyes.

Immediately, with a thought, he retrieved the Earth Demon Puppet into his storage ring, then lightly touched the void with his toes, transforming into a dazzling golden light that soared into the sky, heading straight towards the sky full of pill lightning!

"Is he crazy?!"

This scene horrified all the alchemists present!
"Boom!"

To everyone's astonishment, the golden figure had already boldly entered the thunderclouds. In an instant, the sky was filled with lightning like a raging beast, and the violent silver-black lightning instantly engulfed Lu Yu!
