A few days later, in the Rongyuan Demon Cave, Shi Yin'er's figure had disappeared, only a three-zhang tall giant, and a circular ball of light composed of demonic energy was swirled around its body, exuding terrifying coercion.

I don't know how long it took, this huge body trembled slightly, and began to shrink, and after a while, the giant turned into a six-foot tall, and the surrounding demonic aura gradually sank into the rich demonic qi.

Lu Kun had just used the magic power of heaven and earth to attract demonic vitality into his body, repairing the five internal organs that had been injured because of the consciousness shock wave of the sharp intent.

With a strange aura of destruction and life, he slowly opened his eyes, feeling the vigorous internal organs, and a smile appeared on the corner of his mouth.

"After the tempering of several alien wills, the strength of the internal organs increased again, reaching ten percent of the life strength, and just one cycle was enough to cultivate all the life force. ”

"According to the cultivation experience in the early stage of bone transformation, the life force in the body can be doubled in order to reach the threshold of the late stage of bone transformation, and with sufficient life force, the blood can store magic energy and increase the storage of magic energy. ”

"The improvement of internal organs has shortened the cultivation time of life force, at least two or three times faster than before, and you can start the cultivation of the middle stage of bone transformation. ”

After Lu Kun used the Transformation of the Law Phase Heaven and Earth and the Demon Ape for the first time, he roughly deduced the cultivation method of this realm, and with some comprehensions of the Great Zhou trip, he had perfected it.

The cultivation goal of the middle stage of bone transformation is to strengthen the concentration of essence blood and transform it into bone treasure cells, if this is achieved, other bodies will be able to cultivate to the late stage of bone transformation, even if there is no silver dragon meteorite, they will be able to cast the magic power of heaven and earth.

However, the transformation of blood into bones is different from the integration of flesh and blood, it is a unilateral transformation, and Lu Kun has no clue about how to reverse transform blood into bone treasure.

The mid-stage cultivation of bone transformation that he deduced had three stages.

One of the stages is the same as the initial stage, through the circulation of the spine and internal organs, absorbing essence and blood energy and improving the life force.

In the second stage, Lu Kun called it blood bone smelting.

Through the multiple performances of the Law Phase Heaven and Earth and the Demon Ape Transformation, and comprehending the mystery of the changes in the blood and bones, Lu Kun found that the key to the transformation of blood into bones is the same as the bottleneck in the early stage of bone transformation, which is tendons.

The free transformation of blood into muscle is to use the tendon as a node to expand it and grow muscle, and among the components of muscle, the tendon material is closest to bone, and the blood is the closest to bone at the moment of transformation into tendon.

Blood and bone smelting, which first transforms blood into tendons, and then stimulates the power of destruction to temper the tendon nodes of the whole body, so as to increase the texture and concentration of blood.

The realm of the entire bone transformation period is the transformation of the integration of the flesh and body, and the material characteristics of the bone treasure are transferred to the whole body, the initial stage is the transition to muscles, and the middle stage is blood.

......

With the cultivation method echoing in his mind, Lu Kun slowly walked to the intersection of the spiritual qi pillar and the rich demonic qi, and the power of qi and blood gushed out from his body like a vast ocean.

These thick blood surged to the surface of the bones, and silver tendon flowers appeared everywhere in the bones, and the original tendon area was thus expanded by half.

At the same time, the muscle fibers swelled up, like solid rock balls of flesh, hanging on Lu Kun's body, deformed and hideous, and the amazing power of destruction emerged from the bones and muscle balls.

In the early stage of bone transformation, only the bones store magic energy, and in the middle stage of bone transformation, there is also magic energy in the muscles, and these magic energy attracts the power of destruction, one outside and one inside, quenching the blood in the tendons.

When the blood is tempered by the power of destruction and cannot maintain the tendons, other blood flows.

As long as the blood cells in the whole body are tempered at the tendons, he has completed a round of cultivation.

"The cultivation time of life force has been greatly shortened because of the strengthening of internal organs, and this blood bone smelting can also increase the cultivation speed. ”

A glimmer of golden light flashed in Lu Kun's eyes, his burly body trembled slightly, more than two hundred bones in his body creaked, and the luster of the silver dragon meteorite and the change magic circle on the bone treasure brightened.

The body was quickly elongated, and it turned into a giant three feet high.

"The bones have been magnified five times, and although the blood stock in the tendons has not changed, the refining area of the power of destruction has surged several times, and the speed of each round of blood refining has greatly increased. ”

"The consumption of the Law Phase Heaven and Earth is amazing, but in the Rongyuan Demon Cave, an environment with a strong demonic aura, the replenishment speed of demonic energy is extremely fast, and as it comes and goes, the cultivation speed of blood and bone smelting has accelerated a lot. ”

With the passage of time, Lu Kun gradually completed a round of cultivation of blood and bone smelting, and he quietly sensed the blood in his body, which was compressed by a few points and became more condensed.

He whispered in his heart, "Next is the third stage of cultivation, which is to conceive and nourish the bone marrow. ”

Quenching blood like this can only ensure the concentration of blood in this round, and the blood in the human body is continuously produced through the bone marrow.

"You can't increase the speed of bone marrow, but you can use this time to restore your magical energy. ”

Thoughts flashed through his heart, and his huge body gradually shrunk and returned to its normal size, and the rich demonic aura around him surged towards his physical body.

In this way, Lu Kun cultivated in a cycle of three stages, and completely entered a state of retreat.

......

......

Qingzhou of Wei State, in a certain cave in the depths of the Spirit Pavilion.

A naked man with a strong body stood opposite a giant bear, their skin and fur surface, with dozens of knife marks, extremely hideous.

This person and a bear are the martial artists who worshiped the Refining Pavilion many years ago, Xiong Mountain, and his spirit beast, the Giant Spirit Bear.

"Sneer......"

Xiong Shan held a short knife with golden light, stuck it in his chest, and cut the skin and flesh expressionlessly, as if he didn't feel pain, and the corners of his mouth didn't twitch.

Beneath his skin was a wide sternum, one size larger than the bones of ordinary humans, and his left hand was wrapped in a layer of pale yellow light, which reached straight in.

With a creaking sound like grinding teeth, this deformed sternum was forcibly pulled out.

"Little zongzi, this is the last bone. ”

The Djinn Bear nodded obediently and puffed out his chest.

Xiong Shan's eyes narrowed, and he pulled out a short knife, with a strong wind and golden aura, and inserted it into the chest of the giant bear, and then pulled out a relatively thin sternum in the same way.

As he spoke, two bones levitated, emitting a pale yellow glow, one staggered, the small bone entered the chest of Xiong Shan, and the large deformed sternum submerged into the body of the giant spirit bear.

Xiong Shan's expression was a little complicated and embarrassed: "Little zongzi, it's been almost a hundred years, and the bones implanted by that old witch have finally been replaced by our own hands." ”

The djinn bear's eyes were very smart, with a bit of pain in them, and he whined twice.

Xiong Shan was silent for a moment, a force of qi and blood rose in his body, he carefully sensed the bones in his body, and muttered: "Fortunately, I waited until you entered the second-level demon beast before I tried to change the bones again." ”

"I didn't expect that the qi and blood energy bred in the bones was so rare, I'm afraid it was only smelted in it after you broke through to the second level, and the demon spirit power and blood flowed. ”

"Although qi and blood energy are scarce, I can also try. ”

A hint of determination flashed in Xiong Shan's eyes: "Little Zongzi, I'll leave it to you next, as quickly as possible, smash the bones of my whole body, only when the bones are broken and the blood is clotted, can I have the opportunity to absorb the qi and blood energy and refine the bloodline of the demon clan." ”

The giant spirit bear climbed up, looking at Xiong Shan's body that was a few sizes smaller than him, with a little worry and reluctance in his eyes, and whining in his mouth.

"I naturally know that these bones have not undergone the cultivation of the Demon Spirit Technique, and it is not a small risk to break through the blood coagulation stage, but if it were not for the seniors of the Body Refining Pavilion to save us, we would have died a long time ago, how could we have a chance to enter a higher realm. ”

"Woo......"

Xiong Shan's eyes widened, and he shouted: "Don't do it yet!"

The giant spirit bear was clever, let out a roar, and seemed to cheer himself up again, and the pair of thick bear paws slapped down against the body of the Xiongshan human race.

"Click......"

"Hiss......"

Then, the cave was filled with the sound of bones shattering and the cries of Bear Mountain's pain......
