"I didn't expect that the blood magic power of the nine-fold foundation building Great Perfection would be able to enter the middle stage of the knot pill in one go after being compressed to double, and the total amount would be no different from the demon cultivation in the middle stage of the knot!"

Lu Kun felt the surging blood magic in his blood, and his expression was extremely surprised.

He burned essence blood, and with the power of qi and blood, combined with the accelerated flow of mana and blood, he forcibly squeezed the blood magic power to double.

After the blood magic power was compressed to the extreme, it was like a bomb that would explode in his body at any time, and with such a quality of blood magic power, the little True Demon intent remaining in his body was not enough to urge the Blood Demon Skill Mantra, so he ventured into the True Demon Pool.

Thanks to Lu Kun's decisiveness, the true demon intent required for the transformation of blood magic power was far beyond his imagination, and it took a quarter of an hour in the true demon pool to barely break through the barrier.

Finally, with the assistance of sufficient demonic energy, the blood magic power entered the middle stage of the knot pill in one fell swoop.

The reason why the Blood Demon Bone Alchemy in the middle stage of the Bone Treasure encountered a bottleneck was because the energy level of the Blood Demon Power was too low, and the annihilation power generated by the two could no longer temper the formed Bone Treasure.

According to Lu Kun's plan, through the comprehension of high-level blood demon skills, let the blood magic power enter the level of the early stage of the elder, then the power of annihilation generated by mana and magic power will have a qualitative change, and the bone treasure can continue to be strengthened.

However, he didn't expect that the nine-star physique that had appeared in the quenching stage would bring so much help to the middle stage of the bone treasure, causing the blood magic power to surge to the level of the middle stage of ten percent of the knot pill, which was comparable to his thunder attribute mana.

Obviously, the blood magic power in the middle stage of the knot pill is fused with the thunder attribute mana, and the power of annihilation produced is definitely much greater than the blood magic power in the early stage of the knot, and the speed of refining the bone treasure will be faster.

"In addition to the blood magic, the density of the blood has been raised to a higher level, and the weight has been reduced, as if it has been re-refined and become more refined, hey, the color of the blood has changed to dark gold. ”

"Even if the blood magic power is greatly increased, the current blood can completely seal it, recover the mana first, and try the current blood demon bone alchemy, how effective it will be. ”

Lu Kun was a little impatient, he used the blood in his body, and the concentrated blood crystals wrapped the magic power of the middle stage of the knot, and through the transportation of blood, it sank into the depths of the bone marrow cavity.

Then his figure flashed, he came to the outside of the cave, took out several magic disks, arranged a magic circle that simply isolated the demonic qi, and then held several spirit stones in his hand and began to recover his mana.

Two days later, Lu Kun's physical mana returned to its peak, and with anticipation and apprehension, he slowly released the blood magic power deep in the bone marrow cavity.

"Boom!"

An explosion sound appeared in Lu Kun's body out of thin air, and then a large amount of purple treasure light poured out, and the strong magic light accompanied by the aura of destruction filled this undersea demon cave.

Lu Kun sat cross-legged on the ground, his body twitching unconsciously, and his facial expression was even more hideous, as if he was enduring some kind of extreme pain.

He gritted his teeth, and his teeth that were as hard as magic weapons made a squeaky grinding sound, and even a trace of sparks.

Although Lu Kun had expected it, he still underestimated the power of annihilation generated in the middle stage of the knot, and only released a little blood magic power, and the power of annihilation that erupted in the bone marrow cavity almost made his bones fall apart.

Fortunately, all the bone treasures have depicted a solid magic circle, and the treasure light is lit up at the moment of crisis, resisting the power of the power of annihilation, otherwise the bone treasure will definitely suffer a great loss of spirituality at the first time, not only will it not be refined, but it will even regress in the material.

Listening to the overwhelming crunching sound of the bones, Lu Kun breathed a sigh of relief, and carried the first round of explosions, which was easy to talk about later.

He endured the severe pain transmitted from his nerves, guided the flow of the power of annihilation, and after this power of annihilation was consumed, he began to reduce the output of blood magic power and continued to refine it.

After three days and three nights, Lu Kun stopped.

At this time, the mana and magic power in his body had all been exhausted, and the two and six bone treasures had been tempered for a whole round, and Lu Kun sensed the changes in the bone treasure in his body, with a satisfied expression.

"As expected, the power of annihilation generated by the blood magic power of the foundation building foundation cannot shake the bone treasure, and the knot pill level is completely fine, just this round of tempering, I feel the enhancement of the bone treasure material. ”

"The only thing that is a little troublesome is that the mana and mana consumption is too great, and it will be used up in one round of quenching. ”

Lu Kun groaned, and then ran the exercises to restore the blood magic power.

The blood magic power in the middle stage of the knot pill was very different from the previous foundation building stage, and it took him a full day to restore the blood magic power to its peak.

Mana gave him a little headache, in this environment full of demonic energy, even if there were a large number of spirit stones, it would take two days and two nights for mana to recover.

If you are in a blessed land with abundant spiritual energy like Demon Spirit Island, the mana only needs one day, but the blood magic power can only be cultivated with magic stones, and I am afraid it will take two or three days.

Thinking of this, Lu Kun smiled a little self-deprecatingly.

"I'm too greedy, the Blood Demon Bone Alchemy itself has greatly accelerated the refining of the Bone Treasure, even if it takes six days to refine one round, compared to the normal pregnancy and cultivation speed of the Bone Treasure, it is many times faster. ”

After settling down, Lu Kun followed the previous steps to seal the blood magic power, and it took two days to regain the mana.

Then he ran the Blood Demon Bone Alchemy and continued to refine it.

But when a trace of annihilation power just appeared in the depths of the bones, Lu Kun's face suddenly changed, he quickly mobilized a huge amount of qi and blood power, and at the same time, the mana surged, and a layer of rich purple thunder shield appeared on the surface of his skin, and lightning shuttled through his body.

Soon, that trace of annihilation power was wiped out by a large amount of thunder attribute mana.

Lu Kun looked scared.

"The Bone Treasure Spirituality is a little damaged, I didn't even notice that the power of the strong magic circle just now has decreased, and I almost can't resist the power of annihilation. ”

Lu Kun frowned.

"In the early stage of the bone treasure, the bones of the whole body still belonged to the category of materials, but in the middle stage of the bone treasure, the bones became a magic weapon, and under the forcible tempering, the spiritual damage also made sense. ”

"For ordinary immortal cultivators in the Dan period, the spirituality of the natal magic weapon is damaged, and they need to use mana to conceive and nourish before they can gradually recover. ”

"Although the degree of spiritual damage brought about by the refining of this round of bone treasure is very low, there are too many bone treasures, and if I concentrate on conceiving and cultivating them, it will take several days. ”

"There are a lot of changes in the Blood Demon Bone Alchemy in the middle of the Bone Treasure, and I still have to try a few more times. ”

Thinking of this, he mobilized the thunder attribute mana in the bones and circulated in the bones.

Ordinary Dan stage cultivators are pregnant and cultivated magic weapons in the dantian, and Lu Kun's mana is in the bone treasure, and the pregnancy and cultivation speed is much faster than that of immortal cultivators, and it took less than four days for the spirit of the bone treasure to be completely restored.

Immediately afterward, Lu Kun continued to run the Blood Demon Bone Alchemy Technique, studying its changes.
