Yu Xuan looked at Lu Kun's excited expression, and was puzzled in his heart.

Even if Li Qianfeng's magic arm can cultivate the body refining magic skill, it is just to make the qi and blood magic power in the demon arm self-sufficient, and at most cultivate to the foundation building period, the master will not be so excited.

Li Qianfeng was even more dazed.

After a while, Lu Kun sorted out the ideas in his mind, smiled at Li Qianfeng, and his divine sense came out of his body.

"Body Refining Magic?"

Feeling the exercise from this terrifying divine thought, Li Qianfeng was stunned for a moment, and then he concentrated on receiving it.

The method of refining the body magic is how to absorb the demonic energy, cultivate the magic power of the body, and then refine the physical body through the magic power, the most critical method of this exercise is in the muscle magic part, and the subsequent realm breakthrough seems to be the same as other body refining decisions.

However, when it comes to the Great Consummation of Quenching the Body, there is no follow-up to this body refining magic skill, and it is an imperfect exercise.

With Lu Kun's divine thoughts, Li Qianfeng had some enlightenment.

The ancestor wanted him to cultivate the muscle magic power of the demon arm through refining the body magic skill, since there is magic power in the muscles, then the qi and blood magic power does not need to return to the meridians, and it can be recovered directly in the magic arm, and the risk is greatly reduced.

And the flesh and blood of the demon arm will gradually increase with the cultivation of the demon skill of refining the body, and the qi and blood magic power can also gradually grow by relying on the flesh and blood of the demon arm.

In this way, the Demon Arm existed independently of his ontology, becoming a branch of the flesh that cultivated the magic power of qi and blood.

......

Half an hour later, after Lu Kun finished teaching the Fa, he waved one hand, and nearly a hundred black stones fell in front of Li Qianfeng, exuding an incomparably pure demonic aura.

"Qianfeng, you have done me a great favor, these magic stones are counted as rewards, go back and study the body refining magic skills well, and be familiar with the use of the magic arm, it will soon be a sect war, this will be your biggest killer weapon." ”

"And in the future, you can ......"

Li Qianfeng was stunned for a moment, and then a look of surprise bloomed in his eyes.

"Alright, you stand down. ”

"Yes, Master. ”

Li Qianfeng restrained his excitement and left the top of the tower.

In the refining process of the Demon Arm, although he has the risk of being devoured by the magic power of qi and blood, the risk comes with the opportunity, and with the Demon Arm, his combat power has greatly increased.

And according to the unique idea of the last transmission of the master's ancestor, he may be able to enter the bone treasure stage in one fell swoop with the magic arm!

......

Seeing Li Qianfeng leaving, Yu Xuan couldn't help but say, "Master, your problem has really been solved?"

A purple-black seventh-level demon bone appeared in Lu Kun's hand, and he said slowly: "Yes, Qianfeng's magic arm has given me great inspiration, you continue to use the assistance of different fires, and I will refine another magic bone magic weapon." ”

"Yes, Master!"

Next, with the assistance of Yuanyang Earth Fire, Lu Kun used the same means to separate the seventh-level demon bones into three groups of gray, black, and purple materials.

The difference is that the purple material is refined into a wide, short, hollow bone, and the structure of its bone marrow cavity is wider than any bone in the previous Demon Arm.

Then several crimson herbs emerged.

This jagged herb is very famous among high-level demon cultivators, called Demon Dragon Grass, and it is the most powerful magic pattern material.

The magic pattern outside the bone marrow cavity is a combination of a solid magic circle and some unique miniature magic circles, which is the basic magic circle of the magic bone magic weapon.

"Yu Xuan, reduce it to the strength of ordinary mana true fire. ”

After speaking, Lu Kun dipped his fingers in the liquid of the Demon Dragon Grass and sketched it outside the hollow bones, and at the same time, his mouth opened, forcing out a ball of silver essence blood, turning into countless silk threads, surging into the bone marrow cavity.

His mind was clear.

"An additional layer of structure needs to be added to the bone marrow cavity, on the one hand, to channel the power of dispersion and destruction, and on the other hand, to allow the demon bones to generate new magical power, so that they can self-nurture and repair. ”

Lu Kun's eyes flashed with gold.

"Then the best way to structure this layer is to create internal muscles in the bone marrow cavity!"

When Lu Kun was used as a material by Pang Lao Mo, he had built the internal reverse muscles of the bones, so that he could control the body of the white bones.

Now the muscles he constructed inside the magic weapon of the demon bone can not only help the bone marrow cavity bear some destructive power, but also use the unique structure of muscle fibers to guide the destructive power and make it vent into the bone layer.

Even if the internal muscles are damaged, Lu Kun can also transmit his own flesh and blood essence to replenish it.

What's more, the internal muscles can also cultivate muscle magic!

Thoughts flashed in his heart, Lu Kun manipulated the essence and blood, and gradually constructed a layer of vascular network in the gap between the magic lines, with the vascular network, he could transport the essence of flesh and blood and construct internal muscles.

He refined this bone wide to leave enough space for the internal muscles.

Because he only refined one bone, Lu Kun quickly completed the construction of the magic pattern and vascular network.

The next refining of the bone layer was basically the same as before, but in order to facilitate the transfer of essence blood, Lu Kun made a little modification to the bone layer at both ends of the bone.

Finally, there is the periosteal layer, in addition to simulating human bones, the vascular network of this layer is also combined with the Yuan Ling Array, a flat and wide bone magic weapon, which is close to the palm of the hand, which is very suitable for the use of the Zhen Yuan Palm.

So Lu Kun controlled the blood essence, and according to the source power operation mode of the Zhen Yuan Palm, he sketched the corresponding Yuan Spirit Array, so that this demon bone magic weapon could echo with Lu Kun's Zhen Yuan Palm under the urging of magic energy.

......

After a few hours, a gray-black magic treasure that was flat and thick in the middle, with two ends in a circular arc, like a brick, was suspended in mid-air, exuding a strange aura.

Yu Xuan looked at this gray-black brick, a little confused, in his opinion, this magic weapon except for adding a layer of vascular network in the bone marrow cavity, the other refining techniques did not seem to have changed.

As soon as this thought flashed through his mind, Yu Xuan saw Lu Kun spit out two balls of essence blood, one of which covered the surface of the bone, and the other turned into a silver blood mist that penetrated from both ends.

Lu Kun looked at the puzzled disciple and sighed: "Yu Xuan, the biggest inspiration that Qianfeng gave me is that the magic weapon of the demon bone can be self-contained, and with the assistance of flesh and blood, it can generate its own magic power, which solves the problem of repair, after all, the magic energy will only destroy." ”

As he spoke, a huge amount of qi and blood power rushed up from this magic treasure, solid tendons emerged from both ends of this magic treasure, and then muscle fibers staggered and squirmed on its surface.

Yu Xuan's eyes widened, before Li Qianfeng transferred the flesh and blood to the demon arm, he could still accept some of it, but in front of him was a brick-shaped magic weapon.

Growing flesh and blood on the magic weapon? This visual impact is a bit big.

Yu Xuan only saw the surface of the magic treasure, and if he saw the bone marrow cavity inside, I am afraid it would be even more incredible.

Unlike the outside, the muscle fibers in the bone marrow cavity are densely packed, intertwined like honeycombs, not like human muscles at all, there is no force point, just a very disgusting mass of flesh and blood.

Soon, the magic treasure turned into a strong, deformed muscle mass.

Lu Kun threw out a bunch of black magic stones, and the power of the void shattered the magic stones into pieces, and the pure and rich demonic qi wrapped this deformed muscle.

Immediately after, the deformed muscles quickly trembled, like a powerful heart, beating, and the air felt dull, as if some kind of evil creature was being bred.

The rhythm of the beating kept changing, and after about a quarter of an hour, the surrounding pure demonic qi was guided by some kind of guidance, surging towards the deformed muscle mass in the center, and a unique magical aura came out.

Lu Kun's physical body is the Five Elements Chaos Demon Body, which has both demonic attributes, and the flesh and blood essence can naturally match the demonic qi, but the internal and external muscles of this demonic treasure are a little different, and he adjusted the method of refining the body demonic skills before he successfully cultivated the magic power.

Then he manipulated the deformed muscle mass, absorbed a large amount of pure demonic qi, and injected essence blood into the demonic bones from time to time.

I don't know how long it took, a magical aura from the early stage of the knot pill came from the demon bones.

Yu Xuan looked at this deformed muscle, swallowed a mouthful of spit, he finally understood the meaning of the demon treasure self-contained system, that is, through the transfer of flesh and blood of physical cultivation, let the demon bone magic weapon cultivate magic power.

Lu Kun stretched out his hand and put the demon bone into his palm, he did not inject magic energy, but carefully observed.

"The muscles of the Demon Treasure have been compressed to the extreme, and at present, they can only accommodate the magic power of the Dan Period, but this is enough, the magic power of the Dan Stage is enough to refine it. ”

"After refining, the magic power will be self-conceived, isn't this the same as the bones of the bone treasure stage. ”

Lu Kun's eyes flashed with excitement.

"With each use, the power of destruction is dispersed by the internal muscles and transferred to the bone layer, and the damaged bone layer and bone marrow cavity are restored after the conception of the magic power. ”

"That is to say, it will be like the bones in the middle stage of the bone treasure, destroying, nurturing, and becoming stronger, and with the increase in the number of uses, the material of the magic weapon will become stronger and stronger. ”

Lu Kun looked at this deformed muscle as if it were a treasure.

"The magic weapon of an immortal cultivator is that the longer it is gestation, the stronger it becomes, and it is likely that the more battles I fight, the stronger I become, and I am simply born for battle. ”

He muttered, "That magic weapon of the bone transformation period might as well be called a war treasure." ”
