More than two months passed in a flash, and the power of qi and blood tumbling on Lu Kun's body gradually disappeared.

He opened his eyes, lowered his head in contemplation, and reviewed his cultivation during this time: "The cultivation in the early stage of bone transformation is similar to the middle stage of bone treasure. ”

"The middle stage of the bone treasure is divided into three stages: refining the bone treasure, restoring blood magic power, mana, and conceiving the bone treasure, as long as there is pure spiritual energy and demonic energy, the cultivation time of this round is about ten days. ”

"The cultivation in the early stage of bone transformation is divided into refining muscles, cultivating life force, nourishing muscles, and restoring the essence and blood of the body. ”

"Compared with the two realms, there is not much difference between recovering essence blood and restoring blood magic power, and the extra part of the bone transformation period is the cultivation of life force. ”

"But even if I perfected the cultivation method of life force, this whole round of cultivation would have taken two months. ”

Lu Kun frowned, his divine sense enveloped his whole body, his muscles were tense and loose, like a dexterous python, swimming around on the surface of his body, he silently calculated in his heart.

"The muscles are in a state of hard stunning, and they will reach the limit after ten days of tempering at most, and the material of two or three ten-thousandths of the material will be improved, and according to the experience of the bone treasure period, the strength will be increased by fifty percent, that is, if you cultivate about two thousand times, you can reach the level of the magic weapon of the maturity stage. ”

"The cultivation of life force and the conception of muscles, after my perfection, can be carried out at the same time, a trace of life force is improved in the internal organs, and the other muscles are conceived and nourished, until ninety percent of the essence and blood are consumed, and it takes almost twenty days of cultivation. ”

There was a sad look in his eyes: "But once the life force is cultivated, it seems that it has only increased by one ten-thousandth, which is very small, and the cultivation speed is far lower than that of muscles." ”

"According to my calculations, the life force will be at least twice as strong as it is now, and it will be possible to enter the middle stage of bone transformation. ”

The reason why Lu Kun wanted to find a way to improve the life force was to make the muscles that had increased in strength also contain magic energy.

Now magic energy can be stably stored in bones, in addition to the incredible strength of bones, because of the existence of life force.

In order to reserve magic energy in the muscles, there must be excess life force to maintain the magic energy, and the muscles are attached to the bones, and in terms of volume and quantity, at least the same life force must be blessed.

If the next body cultivation realm does not have enough demonic energy, even if the physical body is strong, the physical body source power is not enough to support a long battle.

The life force is doubled, the muscles reach the material of the maturity magic weapon in the hard stun state, and the new magic energy fills the muscles of the whole body.

These are several conditions that Lu Kun preliminarily deduced to enter the middle stage of bone change.

But now that he has cultivated, each increase in the power of life is only one ten-thousandth, and to reach the breakthrough limit, he must cultivate at least 10,000 times, twenty days each time, even if there is endless absorption of essence and blood, without stopping, it will take more than five hundred years!

Lu Kun rubbed his chin.

"It can't be counted like that......"

"The speed of muscle refining will get faster and faster, after all, the stronger it is, the more power it can bear, and it doesn't even need bones to filter it. ”

"As for the life force......"

Lu Kun showed a deep groan.

"After two cultivations, the internal organs seem to have changed a little, but they don't improve the material like bones, and it seems to be more in line with the life force. ”

At the beginning, when the life force was transferred to the internal organs, the energy given by this thunder tribulation could only enter a small thread, and if it went in a little more, the internal organs would be in pain, and even the feeling of collapse.

After cultivating twice, he could feel that the pain had been reduced.

"If we extrapolate in this way, as the number of life force cultivation times increases, the life force that the internal organs can hold will also increase, and in the future, its cultivation time will be less than twenty days. ”

"But the recovery of essence and blood ......"

Thinking of this, Lu Kun showed a headache.

His essence blood is extremely powerful, even if it is an eighth-level demon beast, it is much weaker than him, not to mention an immortal cultivator, such a strong essence blood, it will take a month to recover.

In the past two months, Lu Kun has spent most of his time on the recovery of essence and blood.

"If you take two months as a round of cultivation, then in this round, your muscles will increase by two-or three-ten-thousandths, and your life force will increase by one-ten-thousandth. ”

"With such a cultivation speed, even if you exhaust your longevity, I'm afraid you won't be able to reach the conditions of the middle stage of the bone treasure. ”

"The most critical part of improving your cultivation speed is the recovery of your essence and blood!"

Lu Kun's brain was spinning rapidly:

"Yuan Infant Stage Immortal Cultivators, if they only absorb aura, the increase of mana is also slow, so they will look for various elixirs to increase their cultivation speed. ”

"Is it possible for the Bone Transformation Stage Body Cultivator to find a relevant spirit herb pill that can increase the recovery speed of essence and blood?"

Lu Kun had encountered a similar elixir, which was the Qi and Blood Pill of the Nine Pyloric Sect back then.

Today's Body Refining Pavilion has completely perfected this elixir, using the essence and blood of the body cultivation itself as a material, and taking it in battle, it can significantly improve the staying power.

But how can the essence blood consumed by oneself be used for the recovery of one's own essence and blood? unless there is some kind of spiritual grass that can directly enhance or speed up the recovery of essence and blood, and change it into a new Qi and Blood Pill.

He thought for a moment, then shook his head helplessly.

"My essence and blood are already very powerful, even if ordinary immortal cultivators find such herbs, they are also highly poisonous, such a powerful qi and blood thing will only make the weak body of the immortal cultivator explode to death. ”

"There may be such herbs in the immortal cultivation world, but if you want to find them, it is tantamount to looking for a needle in a haystack, and it is impossible in a short time, but if you don't start with herbs, what is the way?"

Lu Kun thought for a long time, and suddenly his mind moved.

"By the way, my own essence blood is not good, what about the essence blood of other powerful creatures, and I have qi and blood magic, so I don't need to be so troublesome as refining it into an elixir. ”

"Hong Yuntian used this strange energy to even devour the flesh of a high-level demon. ”

"The magic energy in my body, the mana and magic power it separates, all have the devouring attribute of qi and blood magic power, so can I use it to devour and absorb the essence blood of other powerful creatures, trying to speed up the recovery speed of essence blood?"

Lu Kun's understanding and use of qi and blood magic power has long surpassed that of the two Hong Yuntian brothers.

At the beginning, when he broke through the bone transformation stage, he used the magic power of qi and blood to devour the two demon zombie qi and blood demon pills, and the flesh and blood essence mixed with the two qi and blood demon pills was purified by him with the power of annihilation, which greatly increased the qi and blood magic power in his body at that time.

After that, he created a meridian strengthening method for the sword cultivation of the Heavenly Sword Gate, and even flexibly used the strange characteristics of qi and blood magic power, using his essence and blood as a medium to transfer the essence of the immortal cultivator's body to the meridians.

"Hong Yuntian is using the magic power of qi and blood to devour the essence of the flesh of the sub-body and replenish his own body, but I, Lu Kun, are different, the flesh is all refined by myself, and simply devouring the essence of the flesh body has no effect at all. ”

He seemed to have thought of something, and his expression was a little excited.

"The essence of the demon clan's flesh is quite powerful, but what is really useful is not necessarily the flesh and blood essence, in the eighth-level demon cultivation body, there is also a kind of energy, which is hidden in the depths of the internal organs and blood vessels, and can be absorbed by the power of life, and the effect of the essence and blood in my body is similar. ”

"If I could devour it......"

Lu Kun's eyes flashed with excitement, and with a wave of one hand, the corpse of the eighth-level wolf demon appeared on the ground.

His mouth opened slightly, and he spat out clumps of silver blood, which gradually became compatible until they grew to the size of a watermelon, and then flew forward, submerging into the wolf's cracked back.
