Chapter 419 Deduction of the Pill Formula

Eldrin returned to Spirit Isle Lake and began studying a new alchemy technique, referencing the Chen family's collection of Meridian-Tempering Elixir formulas.

With his current alchemy proficiency, studying low-grade pill formulas was hardly challenging.

Merely a second-tier, low-grade Body Refining Pill, yet it could enhance the strength of a Qi Refining cultivator's meridians by 30 percent after they had been tempered to their limit—this was truly remarkable.

Without advancing the grade of the pill, enhancing its efficacy through the principles of monarch, minister, assistant, and envoy, along with precise medicinal ratios, is in fact an exceedingly challenging step.

To deduce the formula for the Meridian-Tempering Elixir, Eldrin even resorted to using Enlightenment Tea, harnessing its mind-clearing and insight-enhancing properties to comprehend the alchemical recipe.

After a full year of ceaseless work, he had continuously refined the alchemical formula, gradually enhancing its medicinal efficacy until it finally reached a remarkable 50% improvement.

"Close enough."

Gazing at the recipe before him, Eldrin murmured to himself.

Through his continuous research, this newly refined Meridian Tempering Elixir could increase a Great Perfection Qi Refining cultivator's meridian strength by 50 percent.

At this stage, it had become exceedingly difficult to further enhance the medicinal efficacy unless 1 could advance the pill's grade.

In fact, even among many top Golden Core immortal clans, the treasured second-tier low-grade Meridian Tempering Pills they possess can only enhance efficacy by 30 to 40 percent at most.

Eldrin was able to deduce a Meridian-Tempering Elixir formula with 50 percent efficacy—a feat that would likely rank among the world's finest, rivaling even the Meridian-Tempering Elixir formulas possessed by Nascent Soul immortal clans.

After creating the pill formula, Eldrin personally ignited the alchemical furnace and refined 1 batch of Meridian-Tempering Elixir.

Looking at the Meridian Tempering Pill veined with pale purple patterns, he exclaimed with delight, "This pill is adorned with purple veins—let it be named the Violet-Veined Meridian Tempering Pill."

After successfully concocting the pills, Eldrin journeyed to Verdant Chariot Mountain and summoned 3 cultivators preparing for self-established foundation.

After meeting with the 3, he distributed the Purple Vein Tempering Pills and said, "Give these a try. Let's see by how many tenths they can strengthen your meridians."

The 3 of them accepted the elixirs and consumed them on the spot.

Had it been a new elixir developed by an ordinary individual, 1 would certainly not dare to consume it so recklessly. However, Eldrin was a fourth-rank, superior-grade Alchemy Master.

If a top-tier alchemist’s research into a second-grade, low-tier pill still resulted in severe side effects, it would be nothing short of a colossal joke.

As expected, no mishaps occurred. After consuming the elixirs, the 3 secluded themselves for 3 full days. When they opened their eyes on the third day, astonishment shimmered in their gazes. "Our meridian resilience has increased by a full 50 percent."

"Good."

A gleam of joy flashed in Eldrin's eyes. With his meridians enhanced by 50 percent, coupled with the formation's amplification of both his physical body and meridians by another 50 percent, the effects were nearly comparable to consuming a Foundation Establishment Pill.

The Foundation Establishment Pill (Spiritual Object) could double the strength and resilience of a cultivator's meridians, while also tempering their spiritual energy to become more gentle.

Although the spiritual energy would grow extremely volatile during self-initiated Foundation Establishment, with meridians strengthened twofold, the backlash would likely be far less severe.

At this thought, Eldrin said, "Go into seclusion to build your foundation. I wish to observe the results."

"Many thanks, Ancestral Elder."

The 3 nodded and immediately stepped into the formation to begin their assault on the Foundation Establishment realm.

Not long after they entered, the old clan leader received the news and hurried over. He asked with delight, "How effective was it?"

"It can increase meridians' strength by 50 percent." Eldrin smiled as he spoke, then added with a light laugh, "Now let's see how it performs when combined with the formation."

The old clan leader also nodded, joining Eldrin (Person Name) in anxiously waiting outside the secluded cultivation chamber.

In the blink of an eye, 3 months had rushed by. The 3 individuals emerged from the formation, their faces pale as if drained of vitality. "Eldest Ancestor," they spoke with bowed heads, "we have failed you."

The old clan leader extended his divine sense into their bodies, then revealed an expression of ecstatic joy: "They've only suffered severe depletion of vital energy, with some fissures in their meridians—nothing more."

"With such injuries, you’ll only need 5 years of rest to recover."

At this thought, the old clan leader spoke to the 3 with a grave expression, "The matters of the formation array and the elixirs must never be disclosed. Otherwise, I will personally ensure your demise."

"We understand."

The 3 hastily nodded and swore a Heart Demon Oath.

The old clan leader still felt uneasy, so he infused a wisp of the Golden Flame Sword's sword intent into the 3 individuals. With a grave expression, he declared, "This formation and the elixirs are vital to our clan's survival. I have left a trace of sword intent within you."

"If you dare to speak of this matter, even if you flee to the ends of the earth, you will not escape the peril of having your soul obliterated."

The 3 of them turned deathly pale and hurriedly swore oaths repeatedly, vowing to keep their lips sealed.

Seeing the terror on the 3 men's faces, Chen Changxuan reassured them, "Rest assured, as long as you keep your lips sealed, this sword intent will not be triggered."

"Moreover, this Golden Flame Sword Intent is profoundly mystical. If you can thoroughly comprehend it, your combat prowess will undoubtedly stand out among peers of the same realm."

The 3 of them finally nodded, letting out a slight sigh of relief.

Eldrin watched calmly, waiting until they had finished speaking before stating, "You may withdraw for now."

Yes.

After the group had departed, the old clan leader sighed helplessly. "When I planted the sword intent, I didn't consider their feelings beforehand. Next time something like this happens, it would be best to give them advance notice."

"Desperate times call for desperate measures. Since they've enjoyed the family's privileges and resources, they must naturally bear the corresponding responsibilities."

Eldrin (Person Name) chuckled warmly, his eyes crinkling with delight as he pulled Chen Changxuan closer. "Uncle, there's no need to be so tense," he said, pouring a cup of tea for the older man. "Though these formations and elixirs are quite effective, they ultimately only benefit low-level cultivators."

"With our strength, even if word gets out, it won't cause us too much trouble."

Chen Changxuan nodded. Although this formation and the elixirs were astonishing, they were practically useless to high-level cultivators.

Among the Nascent Soul immortal clans under heaven, each possessed their own profound foundations. If these 2 treasures were separated and evaluated individually, they might not surpass what the Nascent Soul clans possessed by too significant a margin.

Especially the Meridian-Tempering Elixir. Although this substance is rare, it would not be beyond the reach of high-level alchemists to develop something comparable.

However, this Spirit Gathering Protection Array was exceptionally rare, and it could even stack with the Meridian Tempering Pill, ultimately greatly reducing the backlash.

At this thought, the old clan leader said delightedly, "Just 5 years of recovery to fully heal. For most cultivators with Triple Spiritual Roots, they have roughly 2 chances to attempt Foundation Establishment on their own."

Dual Spiritual Roots and Heterodox Spiritual Roots not only accelerate cultivation speed, but also allow multiple attempts before the age of 60, when 1's vital energy begins to decline.

"With this treasure, in less than a century's time, our Chen Clan's Foundation Establishment cultivators will multiply severalfold. Our future potential shall far surpass that of ordinary immortal clans."

A flicker of delight also surfaced on Eldrin's face. With the Spirit Gathering Guardian Formation and the Purple Vein Tempering Elixir, they would undoubtedly forge an unshakable, unparalleled foundation for the clan, nurturing a great number of Foundation Establishment and Purple Mansion experts for the Chen Immortal Clan.

At this thought, Eldrin added, "To refine the Purple Vein Tempering Elixir, we still need a low-grade tier-2 spirit herb—the Purple Vein Flower."

"The stock of these Purple Vein Flowers in the family's inventory is not substantial. We'll need to build up a larger reserve going forward."
