Everlasting

"Invisible sword."

Jiang Linglong's eyebrows moved, and a hint of surprise flashed across her face.

Intangible gold is extremely rare and precious. The method of refining the invisible sword is also very mysterious.

Different from ordinary third-level fairy swords, if you want to refine the invisible fairy sword, you need superb formation and weapon refining skills to successfully refine it.

Moreover, this sword does not absorb the essence of the five elements, but it requires 108 kinds of elixirs to be repeatedly tempered, and it takes 7,749 days to successfully refine it.

These elixirs are very precious, and they also require three Ningxu grasses. Each Ningxu grass is worth more than 30,000 spirit stones. It is difficult for Chen Nianzhi's identity and status to collect these 108 elixirs.

"These elixirs are expensive. With this invisible treasure and the refining method, the cost of your invisible fairy sword is probably more than 200,000 spiritual stones."

Jiang Linglong said this, but nodded again and said: "However, the invisible sword is invisible and can restrain the protective energy and magic weapons. Even a golden elixir monk will be seriously injured if he is attacked by this sword."

“Although it’s a little more expensive, it’s worth paying the price.”

After she finished speaking, she took Chen Nianzhi to the Earth Fire Room.

The Invisible Sword is a third-level high-quality fairy sword, and the difficulty of refining it is considered top-notch among the third-level fairy swords.

Fortunately, Jiang Linglong's weapon refining skills have reached the fourth level, and she is already 100% sure of refining this sword.

I saw her smelting the invisible treasure while saying: "The lethality of the invisible sword is actually not very powerful among its peers. The key lies in its ability to gather breath and break barriers."

"The two most critical sets of formations in this set of immortal swords are one of the invisible breath gathering formations, and the other is the barrier-breaking sword gang formation."

"As long as there are no mistakes in these two key formations, even ordinary Golden Core cultivators will be afraid of the power of this sword."

After about a few days of work, Jiang Linglong methodically carved out several formation patterns.

At this point, the fairy sword is considered complete. From now on, refining it with elixirs is just a matter of time and effort.

The work of refining the immortal sword is relatively complicated and time-consuming. Chen Nianzhi can complete it by himself, so he said: "You can go back to practice. I'm afraid there will still be some troubles over there in Qingyang Mountain in more than ten years."

"Um."

Jiang Linglong nodded. According to her calculations, Old Ancestor Xu's injuries will probably be healed in another twenty years. If it takes more than fifteen years, Old Ancestor Xu's injuries will be mostly healed, and it may be difficult to defeat Qing Qing. Yang Zong.

Not long after she broke through the golden elixir, she still needed to refine a few natal magic weapons. This time was indeed a bit tense.

Although she was a little reluctant to leave, she still stood up. Before leaving, she took out a jade box and gave it to Chen Nianzhi.

"This is Bei Wangzhu?"

Chen Nianzhi took the jade box and found a crystal clear orb in the jade box. He recognized the origin of this object.

The Shell King Pearl is extremely precious and is a rare specialty in the vast swamp. Within thirty years after being refined, this pearl can increase the cultivation speed of the Zifu monks by 50%.

"Well, the Bei Wang Pearl can speed up your cultivation progress."

Jiang Linglong said with some worry: "The Qingyang Sect has been inherited for thousands of years and has a very extraordinary foundation. Once we start a war with them, I may not be able to take care of you."

"And you will probably become a thorn in Ancestor Xu's side, so you'd better break through the middle stage of Zifu as soon as possible so that you can be confident enough to protect yourself."

"I see."

Chen Nianzhi nodded and put the object away.

After Jiang Linglong left, he began to continuously refine the fairy sword with elixirs. He waited until the 108 elixirs were exhausted, and finally succeeded in refining the fairy sword.

"Yin——"

He only heard the sound of the sword roaring like a dragon, and the transparent invisible fairy sword appeared in his hand, blooming with a hazy barrier-breaking sword.

Chen Nianzhi tested it and found that the sword was not only silent when activated, but also specialized in protecting the body and defensive magic weapons.

"What a fairy sword."

Chen Nianzhi showed joy after receiving a new third-level top-grade sword.

Although this invisible fairy sword is not as powerful as the Great Geng Fairy Sword, its effect is probably even three points greater.

After collecting the fairy sword, Chen Nianzhi did not leave immediately. He planned to use the power of earth fire to refine a furnace of nourishing pills.

After years of accumulation, his alchemy skills are now fully guaranteed to break through to the third level mid-level.

At this moment, he opened a furnace to refine the Soul-Calling Pill. It only took him half a month to refine the pill. In addition, he used the method of combining pills taught by Jiang Linglong to refine two Soul-Calling Pills.

After raising his alchemy skills to the third level of middle level, Chen Nianzhi left Tianxu Mountain with his sword and flew all the way back to Lingzhou Lake.

"..."

Xuantie Mountain, Gengjin Earth Line.

Chen Nianzhi was standing in front of the sword-washing pool, quietly cultivating, when suddenly a sword chant rang out from the sword-washing pool.

I saw a sword light rising into the sky and falling into Chen Nianzhi's hands.

"Three years of cleaning the sword, and finally it's done."

Looking at the invisible sword in his hand, Chen Nianzhi's eyebrows moved slightly.

It has been five years since he refined the Invisible Immortal Sword. In the past few years, he has put the Invisible Immortal Sword and Tianhe Renshui Sword into the sword washing pool to refine them in his spare time.

After refining this invisible fairy sword, both its invisible function and its effect of breaking the Gang have increased a lot.

"It's a pity this sword washing pool."

Chen Nianzhi frowned. There was a pool of spiritual liquid in the sword-washing pool that had been accumulated for many years. It could be said to be an extremely precious liquid.

Unfortunately, after successively practicing the Lihuo Guixu Sword, Tianhe Renshui Sword, Red Flame Spirit Sword, Dageng Immortal Sword and the Invisible Sword in front of me, 90% of the spiritual fluid in the pool has been consumed.

In the future, it will take sixty years of accumulation and a period of sixty years to accumulate a quota for sword cleaning.

"The sword-washing pool is good, but it's a pity that the level of the Gengjin leyline is a bit lower."

"If it is a fourth-level Gengjin earth vein, then a third-level immortal sword can be refined every ten years."

"It is even said that in the sword-washing pool in the fourth-level earth vein, each armor can breed the essence of spiritual liquid. Just one drop can increase the power of the fourth-level fairy sword by 30%."

Chen Nianzhi murmured to himself that this was not just hearsay, but there were examples.

The Chu State Cangqiong Sword Sect is called the Sword Sect because they control the Chu State's only fourth-level Gengjin land line.

The pool of treasure liquid in the Gengjin Earth Vein Sword Cleansing Pool is an extremely precious treasure. The Sky Sword Sect's demon refining treasure, the Sky Fairy Sword, relies on the support of that pool of fairy liquid to sustain a sword that can severely damage late-stage Golden Core demons. The power of cultivation.

The Qingyang Sect's Haotian Mirror, the Cangqiong Sword Sect's Cangqiong Sword, and the Ziyuan Sect's Ziyuan Furnace, any of them are demon refining treasures for Demon Piyi.

Among them, the Haotian Mirror can split the earth thousands of miles away, and its power is the most terrifying. The Purple Abyss Furnace can burn all demons and demons, and is invincible in a group attack.

But it was the Sky Sword that killed the most high-level demons. This sword was unparalleled in its killing power and had killed the most Jindan Demon Cultivator Kings.

In the past, Chen Nianzhi's cultivation was insufficient and he only thought that the treasures for refining demons were all fourth-level top-grade golden elixir magic weapons. However, as his cultivation became more advanced, he realized that the treasures for refining demons were all extraordinary.
