Chapter 225 The Ultimate Treasure of Refining Demons

Formless Sword.

Lyra's brow twitched slightly, a flicker of surprise crossing her expression.

Formless Divine Gold is exceptionally rare, a truly precious and uncommon divine metal, and the Method for Forging the Unseen Immortal Sword (Cultivation Art) is equally profound and wondrous.

Unlike ordinary third-tier immortal swords, forging the nascent form of the Unseen Immortal Sword (Magic Treasure) required masterful attainments in both formation arrays and artifact crafting to achieve success.

Moreover, this sword does not absorb the essence of the 5 Elements, yet it requires 1 100 and 8 spiritual herbs to undergo repeated tempering. The refinement process demands 40-9 full days to achieve completion.

These spiritual herbs were extremely precious, among which 3 stalks of Condensing Emptiness Grass were required. Each stalk of Condensing Emptiness Grass was valued at over 30,000 spirit stones. Given Eldrin's (Person Name) status and position, it was nearly impossible for him to gather all 1 100 and 8 varieties of spiritual herbs.

"These spiritual herbs are exceedingly valuable. Combined with this Unseen Treasure Ore and the forging method, the total cost of your Unseen Immortal Sword (Magic Treasure) likely exceeds 200,000 spirit stones."

Lyra said this, yet she nodded and continued, "However, the Formless Sword leaves no trace and casts no shadow. It specifically counters protective auras and magical treasures. Even a Golden Core cultivator would be severely wounded if ambushed by this blade."

"Though the price is steep, it is well worth the cost."

As her voice faded, she brought Eldrin into the Earthfire Chamber.

The Formless Sword was a supreme immortal sword of high-grade Tier 3, whose refinement difficulty ranked among the most formidable even amidst all Tier 3 immortal swords.

Fortunately, Lyra's artifact forging technique had already reached the Fourth Layer, granting her absolute certainty in crafting this sword.

While refining the Formless Treasure Gold, she remarked, "The Formless Sword's lethality isn't particularly remarkable among treasures of the same tier. Its true essence lies in its ability to conceal spiritual resonance and breach defensive barriers."

"Among this set of immortal swords, the 2 most crucial arrays of runes are the Formless Breath-Concealing Array and the Barrier-Breaking Sword Aura Array."

"As long as these 2 crucial arrays remain flawless, even an ordinary Golden Core cultivator would fear the might of this sword."

After roughly a dozen or so days had passed, Lyra (Person Name) methodically completed the engraving of several formation patterns.

At this stage, the immortal sword could already be considered complete. From here on, refining it with spiritual herbs would merely be a matter of patient, meticulous effort.

The refinement of the immortal sword was a rather tedious and time-consuming task. Since Eldrin could manage it on his own, he said, "You should return to your cultivation now. In a dozen or so years, there may still be some trouble brewing over at Qingyang Mountain."

"Hmm."

Lyra gave a nod. According to her calculations, if they waited over 20 years, Elder Xu would likely fully recover from his injuries. Even if they delayed just 15 years or so, his wounds would be mostly healed, making it nearly impossible to seize control of the Qingyang Sect.

Having just broken through to the Golden Core realm, she still needed to consecrate several of her Natal Magic Treasures. The timing was indeed rather tight.

Though somewhat reluctant, she rose to her feet. Before departing, she retrieved a jade box and handed it to Eldrin.

"This is... the Shell King Pearl?"

Eldrin took the jade box and found a crystal-clear treasure pearl inside. He recognized its origin.

The Shell King Pearl is exceptionally precious, a rare treasure unique to the vast marshlands. Once refined, it can increase a Purple Mansion cultivator's cultivation speed by 50 percent for 30 years.

"Hmm, the Shell King Pearl can accelerate your cultivation progress."

Lyra said with a hint of concern, "The Azure Sun Sect has been passed down for 1 1000 years, possessing an extraordinary foundation. Once we engage in conflict with them, even I may not be able to ensure your complete safety."

Moreover, you will likely become a thorn in the side of Elder Xu as well. It would be best for you to break through to the Purple Palace, Mid Stage as soon as possible, so you can have sufficient confidence in your ability to protect yourself.

"I understand."

Eldrin nodded and still tucked the item away.

After Lyra (Person Name) departed, he began continuously tempering the immortal sword with spiritual herbs. Only after all 1 100 and 8 types of spiritual herbs were exhausted did he finally succeed in consecrating this immortal sword.

"Hymn—"

A dragon-like sword cry rang out as the translucent Unseen Immortal Sword (Magic Treasure) materialized in his hand, radiating a hazy barrier-piercing sword aura.

Eldrin tested it briefly and discovered that not only did the sword activate without a sound, but it also specifically countered protective auras and defensive magic treasures.

"What a fine immortal sword."

Having obtained a new top-tier third-grade, superior immortal sword, Eldrin (Person Name) revealed a look of delight.

Although the power of the Unseen Immortal Sword (Magic Treasure) falls short of the Great Geng Immortal Sword, its impact may well surpass it by a third.

After retrieving the immortal sword, Eldrin did not depart immediately. He intended to harness the power of the earthfire to refine a batch of Soul-Nourishing Pills.

After years of accumulation, his alchemy skills had reached full confidence to break through to the third-tier middle grade.

At this moment, he began refining the Soul-Nourishing Elixir. It took merely half a month to complete the process. Moreover, by employing the Pill-Unification Technique taught by Lyra (Person Name), he successfully produced 2 full Soul-Nourishing Elixirs in this single batch.

Having advanced his alchemy to the middle stage of the third rank, Eldrin finally soared from Celestial Ruins Mountain upon his sword, tracing a path through the skies back to Spirit Isle Lake.

Chapter 1 Dark Iron Mountain (Location), the Golden Metal Earth Vein.

Eldrin stood in silent cultivation before the Sword Cleansing Pool when a resonant sword cry suddenly erupted from its depths.

A sword radiance shot into the heavens before descending into Eldrin’s grasp.

"After 3 years of honing the sword, it has finally taken form."

Gazing at the Unseen Immortal Sword (Magic Treasure) in his hand, a subtle flicker passed through Eldrin's (Person Name) eyes.

5 years had passed since he forged the Unseen Immortal Sword (Magic Treasure). During these years, in his spare time, he would cleanse both the Unseen Immortal Sword (Magic Treasure) and the Li Fire Sword of the Returning Abyss (Magic Treasure) within the Sword Cleansing Pool.

After being refined, this Unseen Immortal Sword (Magic Treasure) saw significant improvements in both its invisibility function and its ability to break through protective auras.

"What a pity for this Sword Washing Pool."

Eldrin furrowed his brows. The spiritual liquid accumulated in this Sword Cleansing Pool over the years could be described as an exceptionally precious treasure.

Unfortunately, after successively refining the Li Fire Sword of the Returning Abyss (Magic Treasure), the Heavenly River Ren Water Sword, the Crimson Flame Qi (Spiritual Root) Spirit Blade, the Great Geng Immortal Sword, and now the invisible sword before him, the spiritual liquid in the pool had already been depleted by 90 percent.

From now on, it would take 60 years—a full cycle of the Jiazi era—to accumulate enough merit for a single Sword Cleansing quota.

"The Sword Cleansing Pool is excellent, but it's a pity the grade of the Golden Metal Earth Vein is somewhat low."

"If it is a fourth-order Eldrin Earth Vein, then every 10 years it can temper 1 third-order immortal sword."

It is even said that the Sword Cleansing Pool within the fourth-order earth vein could nurture spiritual liquid essence every 60 years. A single drop was enough to enhance the power of a fourth-order immortal sword by 30 percent.

Eldrin murmured to himself, for this was not mere hearsay—there was a precedent before his very eyes.

The reason the Azure Sky Sword Sect was worthy of its name lay in their control over the only fourth-grade Gengjin Earth Vein in the Chu Kingdom.

The pool of precious liquid within the Gengjin Earth Vein's Sword Cleansing Pond was an exceptionally rare treasure. It was precisely by drawing sustenance from this divine pool that the Sky-Soaring Immortal Sword—the Sky-Soaring Sword Sect's ultimate demon-slaying treasure—maintained its power to severely injure a Golden Core, Late Stage demonic cultivator with a single strike.

The Vast Heaven Mirror of the Qingyang Sect, the Heaven Vault Sword of the Heaven Vault Sword Sect, and the Abyssal Purple Crucible of the Purple Abyss Sect—each of these stood as supreme demon-subduing treasures capable of making all fiends and monsters flee at the very sight.

Among them, the Mirror of the Vast Heaven (Magic Treasure) could sunder the earth for a 1000 miles, its power the most terrifying, while the Violet Abyss Furnace incinerated all demons and monsters, reigning supreme in mass combat.

However, the Sky-Reaching Sword had slain the most high-level demons and monsters. This blade was peerless in slaughter, having beheaded the greatest number of Golden Core demonic cultivators and monster kings.

In the past, Eldrin's cultivation was insufficient, and he had only assumed that all Demon-Subduing Treasures were Golden Core artifacts of the fourth-tier superior grade. But as his power grew ever more profound, he came to understand that each Demon-Subduing Treasure possessed an extraordinary origin.

Chapter 1 The biting mountain wind whipped through the valley, carrying with it the scent of pine and decay. A lone figure sat cross-legged upon a weathered boulder, his simple grey robes fluttering around him. This was Lin Feng, an outer sect disciple of the Verdant Cloud Sect. For 3 years, he had been stuck at the third level of the Foundation Establishment stage. His spiritual root was of the lowest grade, a fact the other disciples never let him forget. Yet, today felt different. The ambient spiritual energy of the mountain seemed to hum around him, a subtle vibration he had never perceived before. He focused his mind, circulating the basic Qi Refining Art as he had done countless times. The spiritual energy of heaven and earth began to gather, flowing into his dantian in a steady stream. It was faster, purer than ever before. 'What is happening?' he wondered, his heart thudding against his ribs. The bottleneck that had constrained him for so long felt... thin. Fragile. Suddenly, a crisp *ding* echoed within the depths of his consciousness, a sound that seemed to transcend the physical realm. [Detected host soul resonance. System binding... 1%... 50%... 100%. Binding complete.] [Welcome to the Cultivation Acceleration System, Host.] Lin Feng's eyes snapped open. A translucent blue screen, shimmering with faint silver glyphs, hovered before his vision. The characters were alien, yet he understood their meaning perfectly. **Host:** Lin Feng **Cultivation:** Foundation Establishment, Level 3 **Cultivation Method:** Basic Qi Refining Art (Peak Grade) **Spiritual Root:** Mixed Element, Mortal Grade (Low) **Comprehension:** 7 **Luck:** 3 **System Functions:** [Tasks] [Shop] [Inventory] [Map] He stared, dumbfounded. A system? Such things were the stuff of legends, tales told by mortal storytellers. Was this a heart demon? An illusion? Tentatively, he focused his will on the [Tasks] function. The screen shifted. [Newbie Task: Breakthrough] **Objective:** Advance to the fourth level of the Foundation Establishment stage. **Time Limit:** 1 hour **Reward:** 1,000 spirit stones, Low-Grade Spirit-Gathering Pill x10, System Points x100. **Failure:** Cultivation regressed by 1 level. A cold sweat broke out on Lin Feng's brow. 1 hour? Under normal circumstances, breaking through this barrier would take him at least another 6 months of arduous cultivation, if he was lucky. Regression was a fate worse than death for a cultivator. But the system's interface was undeniably real. The hum of spiritual energy around him was intensifying, almost as if it were being forcibly drawn to him by an invisible force. Gritting his teeth, he made a decision. He had nothing left to lose. He closed his eyes again, pouring all his concentration into the Qi Refining Art. The spiritual energy surged, a torrent now instead of a stream. It crashed against the walls of his dantian, scouring his meridians. Pain, sharp and cleansing, lanced through his body. He guided the raging energy, focusing it into a single, piercing point aimed at the invisible barrier within. *Crack.* A sound, silent yet deafening to his soul, reverberated through his very being. The bottleneck shattered. A wave of powerful, pure spiritual power erupted from his core, washing through every muscle and bone. The impurities coating his skin were expelled in a black, viscous film. His senses sharpened; he could hear the rustle of a leaf a 100 paces away, smell the distinct mineral tang of each rock around him. He had broken through. Foundation Establishment, Level 4. [Newbie Task: Breakthrough. Complete.] [Rewards distributed: 1,000 spirit stones, Low-Grade Spirit-Gathering Pill x10, System Points x100.] Another *ding*. The rewards materialized in his system's [Inventory]. He could see the stacks of glimmering spirit stones and the jade vial containing the pills. A fierce, unfamiliar joy surged in his chest. For the first time in years, hope, raw and potent, bloomed within him. He looked up at the sky, where the first stars were beginning to pierce the twilight. The path of cultivation was long and fraught with peril, a journey of thousands of years filled with heavenly tribulations and ruthless competition. But now, he was no longer walking it alone.
