Lu Kun sat in a pillar of spiritual energy in the demon cave, and the pure spiritual energy and the surrounding demonic qi continued to pour into his body.

The muscles of his whole body tensed, like lumps of iron, trembling hideously, and a terrifying aura of destruction flowed through it.

Two months have passed since the last opening ceremony, and during this time, Lu Kun used the rich demonic aura of the Demon Abyss Underground Cave Mansion to explore the cultivation path of the bone transformation period.

After the physical cultivation survives the catastrophe and enters the bone transformation period, the special energy of magic energy is synthesized in the body, and the life force is separated, and the magic energy enters the state of cultivation, and it is self-annihilating in the bones, producing the power of destruction.

However, after the cultivation of the Bone Treasure Period, the bones of the body cultivation have become extremely powerful, and even the power of destruction in the Bone Transformation Stage is very slow to strengthen.

The physical body in the bone transformation stage is the same origin, and even if you don't cultivate, the powerful cellular origin of the bones will imperceptibly spread to the muscles, blood, and internal organs, causing the rest of the body to slowly improve.

Of course, the speed of this subtle transformation is just as slow, if you ignore it, I am afraid that there will be obvious changes in tens of thousands of years, so you need to take the initiative to cultivate and accelerate this subtle process.

According to this, Lu Kun summed up the cultivation of the bone transformation period, which is to take the bone as the core and accelerate the process of assimilation and cultivation of muscles, blood and internal organs.

Muscles are the most powerful part of the body after bones, and they are most affected by bones by attaching to bones through tendons.

Lu Kun's muscles now, in a tense state, his defensive power is no less than that of ordinary magic weapons, and he can withstand the tempering of the power of destruction.

I don't know how long it took, Lu Kun stopped absorbing the demonic aura, his muscles relaxed, he opened his eyes, felt the changes in his muscles, and revealed that it was really like this:

"As I had judged, this rough tempering of muscles simply won't work. ”

"Although the destructive power that enters the muscles is much lower through the dispersion of bones, it still has a strong destructive power to the muscles. ”

"Under the tempering of this destructive force, the muscles are repeatedly broken and reorganized, and the material is rapidly improving, but the activity of the muscles is destroyed by the destructive force at the same time. ”

"If you continue to cultivate like this, the material of the muscles will become stronger and stronger, but if you lose activity, the muscles will become extremely stiff, and they will become dead muscles like Demon Zombie, and you will not even be able to use the method of concentrating flesh and blood. ”

Bones are inherently solid and can be used as a magic weapon to quench.

But the muscle is different, soft as cotton, hard as iron, is its essence, it is an active body.

The muscles are tense and contracted, and they can become as hard as a magic weapon, and when they are relaxed, they can stretch freely, showing amazing flexibility and elasticity.

This kind of nature is not like a magic weapon at all, but like a living body, and it cannot be tempered in the same way as a bone treasure.

Lu Kun deduced in his heart: "The cultivation of the bone transformation period is to gradually assimilate the physical body, the bone is already in the state of the magic weapon of the mature stage, and the muscles must be maintained to this level if they want to metamorphose to this level." ”

"Dacheng's muscles are as hard as they are in the mature state, and secondly, the muscle fibers in the relaxed state can be flexibly stretched and even stretched longer. ”

"After the bone treasure stage is tempered by the power of destruction, it takes time to conceive and recuperate, because the bones are dead things, and their self-repair ability is poor, so they need to be conceived and restored. ”

"But the activity of the muscle is extremely high, and in the process of refining the power of destruction, it can repair the broken muscle fibers by itself, but in the process, its activity is destroyed. ”

"If you want your muscles to be in perfect condition, you need to strengthen your muscles at the same time. ”

"Muscles are not magic weapons, activity cannot be conceived through mana, and essence and blood can only accelerate the repair of tendons. ”

"Only this energy gifted by the Heavenly Tribulation can do it!"

Thinking of this, a rich breath of life suddenly emerged in Lu Kun's body, and this breath circulated between the muscles in a unique way.

Lu Kun muttered: "What can really keep the muscles active is the life force." ”

After entering the bone transformation stage, he has been studying the life force, but except for the separation and fusion of chaos magic energy, he has not found any other role of the life force.

Until Fairy Fang Yuan handed over the Spirit Transformation Decision to him.

A jade slip appeared in Lu Kun's hand, and he showed emotion: "That senior of the Spirit Transformation Sect is really powerful, she can judge that the Spirit Transformation Decision has inspired my body refining exercises, and she must have guessed the life force." ”

"After the thunder tribulation, the body cultivation has seen the power of life in its body, and the same is true for the shape-shifting demon beasts. ”

"The power of life is an indispensable factor for the transformation of the demon beast to make a breakthrough, and by reverse, the cultivation of the body cultivation bone transformation period must also have a great relationship with the power of life. ”

"The thunder tribulation between heaven and earth, although it tries to destroy the body cultivation, but after the breakthrough, the life force left behind is an incomparably precious gift. ”

Lu Kun looked at the "Transformation Soul Decision" in his hand, the life force was running more and more smoothly, and there were bursts of refreshing sensations in his muscles.

The method of using the life force in the Transformation Spirit Decision was very inspiring to him, and Lu Kun found a way to strengthen the activity of muscles with the life force after many repeated experiments.

"The muscle cultivation method in the ostosis stage should be divided into two stages. ”

"The material of muscle fibers is tempered at one stage, and at this time, the muscles of the whole body are tense, maintaining the state of magic weapon strength, and refining it with the destructive power radiating from the bones. ”

"The second stage is to restore and strengthen the muscles through the operation of life force. ”

"If I'm right, the tightness of the muscles is comparable to the magic weapon of maturity, and its stretchability and elasticity are greatly increased, then it will reach the next small realm, the middle stage of bone transformation. ”

Thinking of this, the smile on the corner of Lu Kun's mouth suddenly froze: "Wait, at that time, the muscles and bones are at the same level, and the muscles can also contain magic energy." ”

"The strength and energy of the physical body are transformed at the same time, and only then can they be regarded as entering the next small realm. ”

"But the life force in my body is limited, and even if the muscles can contain the magic energy, the life force is not enough to cover more magic energy. ”

Lu Kun couldn't help but put away his life force and quit his cultivation state, he stood up and paced back and forth:

"The demon beast has transformed from the eighth level, to the middle stage of the ninth level of transformation, and then to the late stage of the tenth level of transformation comparable to that of a great monk, and the life force is becoming more and more intense, so the similarity between the appearance and the human race has gradually improved. ”

"If the spirit transformation is determined to enter the primordial infant stage, it must rely on the life force of the shape-shifting demon beast, and then in the middle and late primordial infant periods, it will rely on a more intense life force. ”

"Therefore, the Yuan Infant Stage cultivators of the Spirit Transformation Sect back then, their cultivation was all spirit beasts that followed him. ”

"If the demon cultivation above level eight breaks through, there will no longer be a transformation thunder tribulation, that is to say, the cultivation of the transformation demon cultivation will increase the life force. ”

Thinking of this, Lu Kun pinched the jade slip in his hand and frowned: "There is only a method for using the power of life in the Spirit Transformation Decision, there is no method for cultivating the power of life, and there is no record of the cultivation method of demon cultivation. ”

"It's strange, Fang Yuan can't have a private collection, is there any taboo about the demon cultivation technique, so it is not recorded?"

After pondering for a long time, Lu Kun shook his head: "Forget it, anyway, I will go to Chu State this time, and when the time comes, I will catch a few transformation demons and study them, if the cultivation method of the bone transformation period can improve the life force at the same time, then it will be truly perfect." ”

"By the way, the prototype of the Battle Treasure hasn't been repaired yet, and it also needs life force. ”
