In the hall of the cave, Lu Kun's appearance changed.

The original height of six feet has risen to three zhang, and the huge body is five times the original one, and the muscles are carved into the flesh like mountain rocks, and the gray soft armor has shrunk into a pair of shorts, which are tied around the waist.

He had turned into a huge giant, squeezed into the small hall, and the height of the ceiling, which had been four feet high, now seemed extremely small.

The silver streamer flowed on the surface of his skin, and within four feet of his body, an invisible force field surged, and the terrifying pressure even stirred up a whirlwind in the hall, and some decorative tables and chairs and vases were shattered inch by inch, and the ground was a mess.

Countless points of demonic aura surged from all directions, enveloping the giant, and they attached themselves to the force field outside, forming several thick black apertures.

Lu Kun's eyes were tightly closed, carefully sensing the direction of the demon's vitality, and constantly adjusting the changes in the source power of his physical body.

As early as in the early stage of bone transformation, he relied on the strength of 1.2 million catties after the explosion of the power of his arms, and created a fist interception technique to intercept the enemy's vitality for his own use.

After entering the middle stage of bone transformation, the radiation range of the source force field has increased to four feet, which can spontaneously attract vitality, and if you bless the interception technique, it is equivalent to weakening the enemy and strengthening yourself.

At this time, the magic power of Heaven and Earth exerted made the enveloping range of the source force field skyrocket by five times, and the control of the Heaven and Earth Yuan Qi also surged, according to Lu Kun's experience in many battles, the Yuan Qi control ability in this state is equivalent to the Great Monk urging the imitation of the Spirit Treasure.

At this moment, Lu Kun clearly felt that under his full exertion, the demonic vitality within the range of twenty zhang was attracted by the source force field and gathered, but at this time, he was not fighting with the help of demonic vitality, but to introduce it into his body.

With the help of the Chaos Five Elements Demon Bone's supernatural powers, he was constantly adjusting the source force field while sensing the direction and flow of the Yuan Qi.

As time passed, the silver streamers from outside the body gradually converged towards the position of the torso, and the invisible force field distorted the air, forming a vague funnel shape above the waist, and a reverse funnel below.

The magic yuan points of light that swirled around were gradually attracted one after another, like a halo nebula, surging towards the top of Lu Kun's head.

Although the openings of these two source force funnels are opposite, their suction power is from top to bottom, trying to introduce vitality from the head and discharge it from the lower body, thus penetrating the internal organs.

With the acceleration and rotation of the upper and lower source force funnels, this Yuan Qi Nebula sank into the huge head with a somewhat reluctant feeling.

Lu Kun's somewhat nervous face suddenly relaxed, and then showed a somewhat strange look.

In the past, the demonic energy was attached to the attack, and he only felt the powerful power contained in it, but now that these ownerless vitality are introduced into the body, the body does not have any special feelings, but these vitality actively avoid the bones and muscles, and it seems to repel the demonic energy inside.

The black nebula followed the blood vessels, passed through the internal organs, and finally separated from the body from the reverse funnel of the lower body, and then returned to the head through the attraction of the source force field, forming a circular light curtain like flowing water outside the body.

It was like a huge black light apple, and Lu Kun's body was the core of the fruit inside.

"Let the demon vitality simply pass through the body, and the internal organs will not react much, or with the help of life force, first try to see if the vitality can be captured by essence blood like the spiritual power of the spirit crystal. ”

Lu Kun's mind moved, and the blood where the demon energy passed began to become stagnant, turning into a semi-crystalline state, trying to lock these demon energy qi.

Who knew that these demon vitality were different from the vitality in the best spirit stones, and they seemed to have a bit of a sense of formlessness, and blood could not condense them.

"Since you can't catch it, try to guide it. ”

Lu Kun's mind turned, and the incomparably thick qi and blood power in his body rolled, and the semi-crystalline blood changed for a while, turning into a spiral, exuding bursts of suction on the outside, rushing in the blood vessels.

Although most of the demonic energy was still indifferent, there was still a small part of it, which was captured by this huge qi and blood suction, and barely attached to it, and then these spiral blood crystals surged towards the internal organs.

At this moment, the internal organs are very small for the blood vessels and the huge body, only a small mass, hanging behind the sternum, and the life force waiting for the opportunity in the internal organs is quickly circulated.

Those spiral blood crystals that passed by the internal organs began to be absorbed by the life force, and a trace of demonic vitality on them also absorbed past.

Lu Kun sensed the change in the life force, revealing a look of great joy, the scene at this time, the same as the previous absorption of the best spirit stone, the vitality was brought into the internal organs by the life force.

As the vitality of this demonic vitality circulated in the internal organs, a trace of cold breath poured into various organs, and the surface of the dry internal organs faintly lit up with a little moist color, and the feeling of throbbing pain in the coldness almost made Lu Kun cry out comfortably.

"Haha, as I inferred, the consciousness shock wave contains the attribute of vitality, and with the assistance of the opposite vitality, the internal organs can be quickly recovered. ”

Lu Kun suppressed his excitement, restrained his mind, and slowly optimized the healing method to improve his efficiency.

In this process, the demonic energy absorbed by the life force is only a small part compared to the amount gathered outside the body, but if the demonic vitality attracted is too small, I am afraid that the spiral blood crystal in the body will not be able to capture this unique energy at all.

Time gradually passed, similar to the speed at which the best spirit stone healed injuries, the internal organs gradually returned to their normal state, and the original dry appearance disappeared.

After the repair, the strength of the internal organs has been improved again, and it can hold almost fifty percent of the life force before, but at this time it has reached sixty percent, which is a huge improvement.

Lu Kun showed a contemplative look, and did not stop, but continued to attract the demon vitality, and the life force containing the vitality was circulating in the internal organs.

Gradually, he was stunned at first, and then surprised, as if he had discovered a new continent.

"This kind of vitality that contains vitality can actually improve the internal organs faster!"

In the process, he found that even the intact internal organs, tempered by such vitality and life force, were slowly improving, and this speed was faster than simply using life force.

Lu Kun couldn't help but sink his mind into it, combined with the contact with the Heaven and Earth Yuan Qi over the years, he had a deeper understanding of this energy.

To put it simply, Yuan Qi is a higher level of energy than Reiki.

The unrefined Yuan Qi and the spiritual energy between heaven and earth are the same nature, and the refined Yuan Qi, that is, the true Yuan of the cultivators in the Transformation Period, is equivalent to the mana after the spiritual energy is refined.

The introductory stage of body refining is to attract spiritual energy into the body to quench the weak body through the change of muscle fibers, and the later stage of body refining is to convert spiritual energy into mana, which circulates and strengthens in muscles, bones, blood, and internal organs.

At this time, he was using the source force to attract the vitality into the body.

"The so-called return of ten thousand laws to the sect, is the use of the vitality of heaven and earth another cycle of quenching? In the future, will it be the same as the cultivators of the Transformation Period, and the vitality will be completely refined? ”

"But what can I refine into, without the power of the Yuan Infant, even if I comprehend the power of will, I will not be able to form the Yuan Shen, let alone the True Yuan, or will it be combined with the life force given by the Heavenly Tribulation?"

Lu Kun took a deep breath, and the source force field around him gradually returned to calm, and those points of demonic energy gradually dissipated, returning to the depths of demonic energy.

The three-foot-tall body quickly retracted, a large amount of blood detached from the muscle fibers, and the rocky muscles were also shrinking, gradually turning into the original six-foot height size.

He sensed the almost depleted magic energy in his body, shook his head, and was in Da Zhou, this was not the time to deduce the body cultivation method.

"Regardless of anything else, this successful introduction of vitality into the body has allowed me to discover a way to quickly improve my internal organs. ”

Lu Kun reviewed the changes in his internal organs in the recent period and summarized it in his heart.

"First of all, you have to let a certain alien will enter the depths of the internal organs, and then purify it with the pure spiritual power of the crystal of the underworld, generate a shock wave of consciousness to shock the internal organs, and finally use the corresponding vitality to treat it, you can quickly increase the strength of the five internal organs. ”

"When I first used the power of one element, the internal organs could only be integrated into less than thirty percent of the life force, but after several refinements of consciousness shock waves, it can now hold as much as sixty percent. ”

"The strength has doubled, does that mean that the internal organs at this time can withstand the two exertions of the power of one yuan?"

A hint of sharpness flashed in Lu Kun's eyes.

"Next, it is likely that we will have to fight with the cultivators of the Transformation Period, if the power of one yuan can be used twice, it will be a completely different combat power, and we will have to spend the water of true demons to try it. ”

Then he closed his eyes, and a high-grade spirit stone and several magic stones appeared in his hand, and he began to recover the depleted magic energy in his body......
