The Dead Sea Demon Cave was under the abyss under the sea, extremely dark, and Lu Kun cultivated for three months in such a dead and silent environment, refining the bone treasure of his whole body for a total of eight rounds.

He found that after each round of refining, the spirit of the bone treasure would be damaged, and it seemed that the power of annihilation exploded inside the bone treasure, so for each round of refining in the three months, Lu Kun spent several days using mana to conceive and nourish the bone treasure.

With these eight rounds of refining, Lu Kun had already explored the difference between the Blood Demon Bone Alchemy and the early stage of the Bone Treasure, and each round of refining after the middle stage of the Bone Treasure was divided into three stages.

The first stage: fuse blood magic and mana in the bones, run the blood demon bone alchemy, and guide the power of annihilation to refine the bone treasure of the whole body.

Stage 2: Spend time replenishing blood magic and mana.

The third stage: Operate the bone mana, slowly conceive the bone treasure, and repair the damaged spirituality of the bone treasure.

The three stages combined, a single round of bone treasure refining, it will take about ten days, if you want to speed up a few points, not only in a treasure place like the Dead Sea Demon Cave or Demon Spirit Island, but also have to consume a lot of spirit stones and magic stones.

In the past three months, Lu Kun has been observing the changes in the material of the bone treasure at the same time, and it can be roughly judged that the eight rounds of refining of the bones of the whole body have increased the material of the whole body bone treasure by one or two thousandths.

Combined with the maturity magic weapon in his hand and his mastery of refining weapons, it is estimated that the material of the bone treasure needs to be increased by at least fifty percent before it can reach the level of the maturity magic weapon.

That is to say, under the condition that the speed of bone alchemy is maintained, it is necessary to quench the whole body bone treasure for about 3,000 rounds, one round every ten days, and more than eighty years of cultivation, so that the bone treasure can reach the bottleneck, and the material is close to the magic weapon of the mature stage.

Now Lu Kun is only more than one hundred and fifty years old, and eighty years later, he will not be more than two hundred and fifty years old, which is only half of the lifespan of a monk in the Yudan period.

Half of the age of Shouyuan is often the moment when the vitality of an immortal cultivator is the most vigorous, and for physical cultivation, it is easier to break through the bottleneck at this time.

Lu Kun's mind flashed with various thoughts, and his eyes bloomed with strange eyes: "The Blood Demon Bone Alchemy has successfully broken through, the road to the Great Success of the Bone Treasure has been paved, and the next big roadblock is the Yuan Infant Stage!"

Through the fate of the One Yuan Secret Realm, Lu Kun learned a lot of information about the Yuan Infant Stage, and knew that immortal cultivators of this level, because of the power of Yuan Infant contained in their mana and magic power, they had an unrivaled crushing effect on low-level cultivators.

Several exercises obtained are also described, when the Dan breaks through the Yuan Infant, in addition to the risk of breaking the Dan into a baby, the most important thing is the comprehension and generation of the power of the Yuan Baby.

However, for Lu Kun, what he wants to comprehend is not the power of the Yuan Infant.

In the secret realm, Lu Kun understood that the physical source power was the power of the Yuan Infant of the body refiner, and it was the key to whether the physical cultivation could break through to the Yuan Infant level.

In order to break through to this great realm and become a true high-level cultivator, he must comprehend the physical source power.

The opportunity of the One-Yuan Secret Realm gave Lu Kun a clear idea of how to generate this special power.

The method of flesh and blood condensation that he is creating is the first step in trying to comprehend the source power of the flesh.

Lu Kun pondered in his mind: "At the stage of conceiving and cultivating the bone treasure, only mana is used, and the muscles, blood, and internal organs are all idle, and I can continue to study the method of concentrating flesh and blood at this stage." ”

"According to my calculations, this is the correct way for my body cultivation to generate the source power of the physical body!"

From Hong Yuntian's notes, Lu Kun summed up the necessary conditions for the generation of physical source power, that is, the muscles, bones, internal organs, and blood of the whole body should become a whole and become the same cell origin.

Hong Yuntian broke through the Yuan Infant Stage for the first time, and the qi and blood magic instinctively wanted to turn the physical body into a whole, directly devouring Hong Yuntian's physical body and turning it into a pool of liquid qi and blood magic.

Hong Yuntian made a mistake, and with the help of the magic demon son and mother, he survived with the body of the tenth-level demon zombie.

Later, this guy used the Demon Zombie Body as a shell, containing the Qi and Blood Magic Power that had become the origin, and in the face of the tenth-level Demon Zombie level body, Hong Yuntian's Qi and Blood Magic Power could not be devoured at all.

Therefore, the stabilized qi and blood magic power gradually appeared in the physical source power.

If Lu Kun wants to comprehend the source power of the physical body, he naturally has to transform the physical body into a whole, but he is different from Hong Yuntian, the most powerful part of his physical body is the bone, and it is impossible to melt the bones of the magic weapon level.

But if he can concentrate his internal organs, muscles, and blood into his bones, then won't his physical body become a whole?

The method of visceral condensation that Lu Kun taught Zhao Qingtian before was to integrate the essence of viscera into the blood, and in the body of physical cultivation, internal organs were relatively the most fragile, so the difficulty of envisceral condensation was low.

Lu Kun has perfected most of this method of concentrating internal organs, and he can even integrate most of his internal organ essence into the blood, and then under the transportation of blood, he can enter the depths of the bones.

In the future, the method of visceral concentration is the method of muscle concentration, and Lu Kun also has a general idea of how to concentrate muscles.

Muscles, also known as skeletal muscles, grow by attaching to bones through tendons, and as the bones become stronger, the skeletal muscles become thicker and stronger, and even the skin on the surface of the muscles becomes like steel.

In the quenching stage, the key part is the tendon, that is to say, the concentration of muscles is the concentration of tendons, and finding a way to fuse the tendons and bones into one will complete the muscle fusion.

The last blood is the simplest, the blood itself is produced by the bone marrow, and with Lu Kun's control over the blood, the blood of the whole body can be concentrated into the bones at any time.

As long as all the essence of the flesh is pressed into the bones, Lu Kun has preliminarily completed the integration of the flesh.

The Bone Cultivation Bone Treasure stage of cultivating the Blood Demon Bone Alchemy was just right for him to study the flesh and blood condensation method of the flesh and blood, which greatly improved his efficiency.

If at the same time as entering the late stage of the Bone Treasure, the flesh and blood condensation has also been perfected, then he can enter the second step of comprehending the source power of the flesh body.

After arranging the cultivation plan, Lu Kun frowned again.

"I have already obtained the Blood Demon Technique of the last three layers, and the content in it directly refers to the early stage of the Yuan Infant, so it can be said that the task of the Latent Blood Refining Sect has been completed. ”

"But listening to what Song Li's old guy said, it seems that Nie Wufeng and Uncle Zhu Siming are not dead yet, and they are likely to be imprisoned in the Blood Refining Sect by Old Demon Pang. ”

"And after a hundred years, I can clearly expose the blood demon cultivation in the early stage of the Jie Dan and become a blood demon of the Jie Dan, maybe I can get a lot of benefits, and many of the Demon Dao exercises of the Blood Refining Sect also have great reference value. ”

Lu Kun pondered for a moment and found that retaining the identity of the Blood Demon Son of the Blood Refining Sect would be beneficial to him and not harmful.

You must know that when he left the One Yuan Secret Realm, even Pang Lao Mo in the late Yuan Infant period did not discover his true cultivation, as long as he was careful, his identity would not be revealed.

"According to Zhang Yiyang's performance in the Blood Refining Sect in previous years, he only needs to show up every once in a while to take on the task, and he won't delay much cultivation time. ”

After having a plan in his heart, Lu Kun closed his eyes, ran the Blood Demon Bone Alchemy Technique, and continued to cultivate.
