Demon-Refining Supreme Treasure

"The Formless Sword."

Jiang Linglong's brow twitched, a hint of surprise flashing across her face.

Formless Treasure Gold Treasure Gold extremely rare and precious, and the method of forging the Formless Immortal Sword is also very mysterious.

Unlike ordinary third-tier immortal swords, the process of forging Formless Immortal Sword requires superb array formation and weapon crafting skills to succeed.

Moreover, this sword does not absorb the Five Elements Essence, but it requires 108 kinds of spirit medicine to be repeatedly tempered, and it takes 49 days to successfully refine it.

These spirit medicine are extremely precious, and three Void-Congealing Grass are also needed. Each Void-Congealing Grass is worth more than 30,000 Spirit Stone. Given Chen Nianzhi's status and position, it would be difficult for him to collect all 108 kinds of spirit medicine.

"These spirit medicine are extremely valuable. Adding this Formless Treasure Gold and the refining method, the cost of your Formless Immortal Sword probably exceeds two hundred thousand Spirit Stone."

As Jiang Linglong said this, she nodded and added, "However, the Formless Sword is invisible and formless, and it is also effective against protective Gang Qi and Law Treasure. Even Golden Core realm cultivator would be severely injured if attacked by this sword."

"Although it's a bit expensive, it's worth the price."

As soon as she finished speaking, she led Chen Nianzhi into the Earthfire Chamber.

The Formless Sword is a superior Higher Vehicle sword of the Tier 3 High-grade, and its forging difficulty is among the top in the third rank immortal swords.

Fortunately, Jiang Linglong's Artifact Refining Art had already reached the Tier 4, so she was absolutely confident in crafting this sword.

As she smelted the Formless Treasure Gold, she said, "The Formless Sword's destructive power isn't actually that strong among swords of the same level; its key lies in its ability to conceal its presence and break through barriers."

"The two most crucial array patterns in this immortal sword are the Formless Breath-Concealing Formation Pattern and the Barrier-Breaking Sword-Force Formation Pattern."

"As long as these two key array patterns are executed flawlessly, even ordinary Golden Core realm cultivators will be wary of this sword's power."

After several days, Jiang Linglong methodically completed the carving of the array patterns.

At this point, the immortal sword is considered complete; further refinement with spirit medicine is merely a matter of time.

Refining the immortal sword is a rather tedious and time-consuming task, which Chen Nianzhi can complete herself. She then said, "You should go back to cultivate. In another ten Azure Sun Mountain."

"Um."

Jiang Linglong nodded. According to her calculations, Xu Patriarch's injuries would probably heal in about twenty years. If it took more than fifteen years, Xu Patriarch's injuries would be mostly healed, and it would probably be difficult to defeat Azure Sun Sect.

She had only recently broken through to the Golden Core realm and still needed to refine several natal Life-bound Magical Treasure, so time was indeed a bit tight.

Although she was reluctant to leave, she still stood up and handed a jade box to Chen Nianzhi before leaving.

"This is Shell King Pearl?"

Chen Nianzhi took the jade box and found a crystal-clear pearl inside. He recognized the origin of the object.

The Shell King Pearl is exceptionally precious, a rare specialty of the Vast Expanse Marshes. After refining it, it can increase the cultivation speed of the Purple Mansion cultivator by 50% for up to thirty years.

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

Jiang Linglong spoke, she added with some concern, "The Azure Sun Sect has a thousand-year history and Bu Fan foundation. If we go to war with them, I may not be able to protect you."

"Moreover, you will most likely become a thorn in Xu Patriarch's side, so you'd better break through to the Mid-Purple Mansion realm as soon as possible to have enough confidence to protect yourself."

"I see."

Chen Nianzhi nodded and put the item away.

After Jiang Linglong left, he began to refine the immortal sword with spirit medicine until all 108 kinds of spirit medicine were used up, and finally he successfully refined the immortal sword.

"Sing--"

A sound like a dragon's roar rang out, and the transparent, Formless Immortal Sword appeared in his hand, radiating a hazy, barrier-breaking sword aura.

Chen Nianzhi tested it and found that the sword was not only silent when activated, but also specifically countered protective Gang Qi and defensive Law Treasure.

"What a wonderful Legend of Sword and Fairy!"

Chen Nianzhi was delighted to have acquired a top-tier, Tier 3 High-grade immortal sword.

Although this Formless Immortal Sword is not as powerful as the Great Geng Immortal Sword, its function is probably even more effective.

After receiving the immortal sword, Chen Nianzhi did not leave immediately. He planned to use the power of the Earthfire to refine a batch of Spirit-Nourishing Pill.

After years of accumulation, he was confident that his Alchemy Art could break through to the Tier 3 Mid-grade.

He started refining the Spirit-Nourishing Pill and completed the process in just half a month. Moreover, he used the Pill-Merging Method taught by Jiang Linglong to refine two Spirit-Nourishing Pill in this batch.

After raising his Alchemy Art to the Tier 3 Mid-grade, Chen Nianzhi flew out of Heavenly Ruins Mountain on his sword and returned to Spirit Isle Lake.

"..."

Darksteel Mountain, Geng-Metal Earth Vein.

Chen Nianzhi was cultivating in front of the Sword-Washing Pool when suddenly a sword's cry rang out from within the Sword-Washing Pool.

A sword light shot into the sky and landed in Chen Nianzhi's hand.

"After three years of honing my sword skills, I've finally succeeded."

Looking at the Formless Immortal Sword in his hand, Chen Nianzhi's eyebrows twitched slightly.

Five years have passed since he forged the Formless Immortal Sword. In the past few years, he has spent his spare time refining the Invisible Formless Immortal Sword and the Heavenly River Ren-Water Sword in the Sword-Washing Pool.

After being refined, this Formless Immortal Sword has gained significant improvements in both its invisibility and its ability to break through protective barriers.

"What a pity about this Sword-Washing Pool."

Chen Nianzhi frowned. The spiritual liquid in this Sword Sword-Washing Pool had been accumulated for many years and could be described as an extremely precious treasure.

Unfortunately, after successively refining the Blazing Fire Return-to-Ruins Sword, the Heavenly River Ren-Water Sword, the Scarlet Flame Spirit Blade, the Great Geng Immortal Sword, and the Formless Sword before him, ninety percent of the spiritual liquid in the pool had already been consumed.

It will take sixty years, a full cycle of sixty years, to accumulate enough for one spot to cleanse the sword.

"The Sword-Washing Pool is good, but it's a pity that the Geng-Metal Earth Vein is of a lower grade."

"If it is Tier-4 Geng-Metal Earth Vein, then a third-order immortal sword can be refined every ten years."

"It is even said that the Sword-Washing Pool in the Tier-4 Earth Vein can nurture spiritual essence every sixty years, and just one drop can increase the power of Tier 4 immortal sword by 30%."

Chen Nianzhi muttered to himself, this wasn't just hearsay, but there were precedents.

The reason why the Firmament Sword Sect of the Chu Kingdom is called the Sword Sect is because they control the only Tier-4 Geng-Metal Earth Vein in the Chu Kingdom.

The pool of precious liquid in the Geng-Metal Earth Vein Sword-Washing Pool is an incomparably precious treasure. The Firmament Sword Sect Sky Firmament Immortal Sword, the supreme treasure for Demon-Refining Supreme Treasure of the Azure Sky Sword Sect, is able to maintain its power to severely injure a late Golden Core stage Devil Cultivator with a single strike only because it is nourished by that pool of immortal liquid.

The Vast-Heaven Mirror of the Azure Sun Sect, the Firmament Sword of the Firmament Sword Sect, and the Purple Abyss Furnace of the Purple Abyss Sect —any one of them is Demon-Refining Supreme Treasure demons, capable of repelling monsters.

Among them, the Vast-Heaven Mirror can split the earth for thousands of miles, making it the most terrifying in power; the Purple Abyss Furnace can burn away all demons and monsters, making it invincible in group attacks.

However, the sword that has slain the most high-level demons is the Firmament Sword. This sword is unparalleled in its killing power and has slain the most Golden Core realm Devil Cultivator and Demon King.

Previously, Chen Nianzhi's cultivation level was insufficient, and he only thought that the Demon-Refining Supreme Treasure were all Tier 4 High-Grade Golden Core realm Law Treasure. However, as his cultivation level became more profound, he realized that the Demon-Refining Supreme Treasure were all extraordinary.
