A week later, in addition to Lu Kun and the four of them, there was another young man with a calm face in the Rongyuan Demon Cave.

This person's name is Yu Lin, he is the second Yuan Infant Cultivator of the Treasure Weapon Pavilion, when he was a child, he followed the Treasure Weapon Pavilion on Abyss Island, and he also cultivated on Demon Spirit Island, and was a disciple of the late Zhu Xiaofeng.

After so many years, with the qualification of the Fire Wood Twin Spirit Root, coupled with the opportunity of the rapid development of the Body Refining Pavilion, he has gained a lot of cultivation resources, and his cultivation has surpassed that of his former master, and in just over three hundred years, he has entered the Yuan Infant Stage.

Yu Lin has been working in the Treasure Pavilion since he was a child, and he has a lot of experience in refining, and today's refining needs the assistance of two Yuan Infant Stage cultivators who are proficient in refining, except for Qin Yushu, he is the only one who is suitable.

......

Heiyan Daojun sat cross-legged in the spiritual energy pillar, and he looked around in surprise, it was not enough that there was a demon pool in this cave, and there was such a pure spiritual energy.

At this time, he also thoroughly understood that the exercises of physical cultivation had a great demand for demonic energy and spiritual energy.

He shifted his gaze to his side, Qin Yushu and Yu Lin, who were inspecting a large number of colorful spiritual materials.

Outside the aura pillar, Lu Kun and Hong Yuntian stood in the demonic qi, the spiritual light flashed in their hands, and a mass of materials with an amazing demonic aura was released, and there were even two demonic corpses with terrifying aura.

Heiyan Daojun was dazzled, although Lu Kun had roughly talked to him about the refining process not long ago, the amount of this spiritual material was too terrifying.

No wonder Lu Kun wanted to pay him, with so many high-grade materials, coupled with the cumbersome refining process, the mana consumed would definitely be less.

Thinking of this, he carefully felt the rich aura around his body, his expression relaxed, and cast a spell in the aura pillar, which was equivalent to soaking in the aura pool, and the mana recovery speed was extremely fast, and it was not so easy to overdraw the origin.

"Okay, there is no problem with the materials, let's start refining, first of all, fuse the spiritual materials, refine the five elements attribute sword body, Black Flame Daoist, urge your natal fire." ”

When Hei Yan heard this, seeing that Lu Kun didn't make any other moves, he couldn't help but be stunned and said, "Please also ask the Lord of the Lu Pavilion to sacrifice the refining furnace first." ”

Lu Kun smiled and said, "Just urge the flames." ”

Heiyan Daojun was a little confused, hesitated, or according to Lu Kun's request, the magic in his hand flickered, and outside the white spiritual energy pillar, a pitch-black flame appeared, burning the spirit black flame.

This strange fire is extremely domineering, and if an ordinary magic weapon sticks to it, it will be spiritually damaged, and only the mature magic weapon has the power to resist.

The soft armor on Lu Kun's body trembled slightly, and it retracted inward, revealing its strong arms, and invisible power surged around him, and spiritual materials flew towards his palm.

Then, in the shocked gaze of the Black Flame Daojun, these materials and Lu Kun's palm entered the flames together.

I saw that the thick palms were like two hard iron felts, striking the spiritual material with terrifying power, making a dull sound.

The Great Elder of the Burning Sun Sect looked at the scene in front of him and showed an incredible expression.

"This ...... Use the palm of your hand as a furnace?"

Although he knew that Lu Kun's physical body was powerful, he never thought that his physical body could be used as a furnace refiner.

Under the powerful firepower and violent concussive power, these materials were split into tiny spiritual particles, and the terrifying power kept beating, but there was no strong wind overflowing, and it was obvious that the power control had reached a subtle level.

"Black Flame, concentrate on controlling the alien fire!"

When Heiyan Daojun heard this, he hurriedly gathered his mind and concentrated on controlling the flames.

Lu Kun's steady voice continued: "Elder Qin, Elder Yu, is responsible for checking the structure and miniature magic circle, and if I make a mistake, I will be the first to alert." ”

"Yes, Pavilion Master. ”

Qin Yushu and Yu Lin had solemn faces, and they used the secret technique of the unity of divine consciousness, and a divine consciousness close to the peak of the middle stage of the Yuan Infant surged, hovering outside Lu Kun's hands.

The Great Cultivator's Origin Alien Fire is extremely powerful for their cultivation in the early stage of the Yuan Infant, if they don't use the Divine Consciousness Unity Technique, as long as the Divine Mind is close for a long time, I am afraid that it will be damaged.

The divine thoughts and mana of the two of them were not enough to participate in the refining, but the magic weapons they refined were experienced, and their research on the depiction of divine consciousness was more in-depth than Lu Kun's, and they had already memorized the miniature magic circle and structure of the Heavenly Battle Treasure.

Lu Kun needs to focus on fusing materials and carving magic circles, and the steps of refining treasures are extremely cumbersome, he is not sure that each magic circle is depicted perfectly, and he needs someone to assist him to remind him to pay attention.

Now it is the first step, refining the Five Elements Blade, just this blade, it will be divided into dozens of parts to refine, every trace of structural error, will lead to problems with the blade closing.

In other words, this five-element sword body is also a complex combination magic weapon, and the subtleties of the structure must also be repeatedly reviewed by outsiders who are proficient in refining, Qin Yushu and Yu Lin are this role.

......

Time passed slowly, and the dull sound of slapping kept echoing in the Rongyuan Demon Cave.

As the spiritual material was shattered into tiny particles, some slightly faint fragments were repelled out.

At this time, traces of silver blood gushed out from Lu Kun's fingertips, twisting into pale silver muscle fibers, like thin threads, interspersed between the spiritual materials.

Those colorful spiritual material particles were woven together in a special five-element orientation, and gradually, more than ten catties of spiritual material were refined into a multicolored blade the size of half a palm.

"Brother Hong!"

With Lu Kun's words, Hong Yuntian's divine consciousness soared into the sky, intertwined with Lu Kun, and a divine consciousness no less than the peak of the great monk emerged.

A pile of spiritual material powder refined by the Five Elements Jade next to him turned into a streamline and flew over.

At the same time, Lu Kun's right finger flashed and shrunk rapidly, and the five fingers were like tiny silver needles, with that amazing divine thought, dotting on this multicolored scale, depicting a small and complex miniature magic circle.

Before the Holy Demon King refined the Demon Dragon Blade, he wanted to refine a treasure that could stimulate the vitality of the demon spirit at the same time, but finally found that the formed killing intention was a pure demon attribute, and it could only be refined into a heavenly demon treasure.

However, the five elements miniature magic circle he envisioned was still preserved in the refining method, otherwise Lu Kun would not have prepared a large amount of spiritual materials.

These internal formations of the Holy Demon King allowed the power of will and the strong demon element to urge the magic power of the Demon King.

This kind of miniature magic circle that converges vitality through will, Lu Kun can't discard it, otherwise it will be useless even if he successfully smelts the bloodline will.

The structure he is now designing is to give these miniature circles new protection.

The experience of refining many battle treasures made Lu Kun's understanding of the body cultivation magic weapon more and more profound.

The primary battle treasure needs the life force of the Heavenly Tribulation to maintain the stability of the magic energy input, and when it comes to the intermediate battle treasure, this can be solved in another way.

Because in the late stage of bone transformation, blood can transform into bone cells, and it can also contain magical energy, and the life force can flow into the battle treasure through the blood to maintain its stability.

The blood of physical cultivation is an indispensable material.

A small blade made of blood as a vein that is interconnected with each other is a small blade that seems to be strong, but under the weaving of blood muscles, it is as soft as a piece of cloth.

However, if it is injected with blood in the late stage of bone transformation, this scale will be covered with a layer of bone layer on the basis of flexibility, becoming as strong as a bone treasure, and the internal magic circle will not be destroyed by magic energy and source power at all.

And there is another advantage of refining in this way, the blood muscle softens the material, enhances the flexibility, and reduces the difficulty of carving the miniature circle by half.

The Holy Demon King was the top god transformation stage cultivator in the immortal cultivation world back then, the first powerhouse of that era, and this kind of miniature magic circle did not have an incomparably strong divine sense, so it could not be portrayed at all.

With the help of the black flame's strange fire, Lu Kun barely reached the calcination strength, and then merged with Hong Yuntian's divine sense, plus many conditions such as freehand refining, to complete the portrayal.

After about half a day, the miniature magic circle on this blade was outlined, Qin Yushu and Yu Lin checked it repeatedly, and after confirming that it was correct, this blade slowly rose and quietly suspended three feet above the black flame.

Then Lu Kun ingested a bunch of spiritual materials and continued the same action.
