Lu Kun's retreat lasted for two years.

During this period, a small thing happened in the Blood Refining Sect, that is, the previous mission of the Abyss of Death, nearly a hundred Qi Refining Stage disciples, plus five Foundation Building Stage cultivators, only a dozen or so people came back alive in the end.

Among the disciples in the foundation building period, only Xu Zihang survived.

According to Xu Zihang's description, at the bottom of that valley, along with the abyss of death, cracks appeared in the ancient prohibition, and in the cave they explored, there was a foundation building Great Perfection zombie that was only one step away from the bronze armor corpse, and two dead creatures at the late stage of foundation building.

The narrow underground cave is completely the home of these dead creatures in the foundation building period, and no matter how many Qi refining period monks there are, there are only five or six people in the same passage at most.

Moreover, the zombie of the Great Perfection of Foundation Building has been lurking underground, and specially went around to the rear to sneak attack five foundation building period monks, and under one face, the disciples of the Chen family suffered heavy casualties.

In the end, only Xu Zihang calmly retreated.

After receiving the news of Xu Zihang's return, the Blood Refining Sect immediately sent two monks of the Yudan Stage to lead the team into the depths of the valley, and indeed found those dead creatures and killed them all.

However, they didn't find what Xu Zihang said, the forbidden rift that connected to the abyss of death, and in the end, it was gone.

In this mission, although the monks in the Qi Refining Period suffered heavy casualties, the more than ten people who survived, after returning to the sect, all exchanged a large number of contribution points, and in the following time, almost all of them entered the foundation building period.

After all, no matter how poor the qualifications are, there are enough Zhuji Dan, and it can also make the monks succeed in building the foundation.

After this incident, the Blood Refining Sect specially strengthened its defenses near the Abyss of Death, regularly arranged disciples to patrol, and at the same time organized a group of disciples in the foundation building period to explore the mountains and valleys near the Abyss of Death to see if there were any gathering points of other dead creatures.

......

In the Southern District of the Blood Refining Sect, in the Zhang Yiyang Cave Mansion, Lu Kun finished his two-year cultivation, slowly opened his eyes, and exhaled a breath of turbidity.

In the past two years of cultivation, Lu Kun's muscle magic power has not changed, and it is still at the level of the early stage of foundation building, but the blood magic power is increasing rapidly.

In the first few months, it first reached 30% of the mana at the beginning of foundation building, then 50% of the mana, and soon reached 10%.

In the next half year, with the consumption of the true demon's will, the accommodating nature of blood increased greatly, and the blood magic power directly entered the realm of the middle stage of foundation building, and continued to grow to fifty percent of the middle stage of foundation building and ten percent of the middle stage of the foundation.

Until today, two years later, Lu Kun's blood fully contained the magic power of the Great Perfection level of the Foundation Building, and at this moment, he was fully agitating the blood magic power, in addition to the surging magic power, he also exuded a brutal aura.

If he is a monk with a slight deficiency in cultivation, his consciousness will even be affected, and his blood magic power contains breathtaking thoughts.

Lu Kun felt the thick blood magic in his body, and his face showed mixed joy.

He was happy, not because of the great increase in mana, but because the purple-black blood essence in the depths of his bones had disappeared by a small half, which meant that the hidden dangers in his body were gradually being solved.

And what he was worried about was that after two years of cultivation, to this point, no matter how he cultivated, the blood magic power would not increase, and in the same way, most of the remaining half-true demonic intent in the bones would not be able to be consumed.

"In the past two years, it is obvious that the true demon meaning in the bones can be discovered, which is the necessary energy of the blood demon skill, no wonder the demon soul said that my current blood is like a fish in water after cultivating the blood demon skill. ”

"But what's going on with this bottleneck, I still have most of my True Demon Intent, and my own Divine Soul Realm is also at the level of the Dan Formation Stage, why can't I continue to cultivate?"

Lu Kun sensed the blood in his body and fell into silence, at this time, his blood had also undergone a huge change from two years ago, with the disappearance of the crystallization of the little half-true demon's will, Lu Kun's qi and blood power had also recovered by a small half.

Under the subtle influence of the secret method of the Blood Demon Skill, the color of the blood turned purple-black, and due to some kind of mutation in the blood, the density increased several times compared to two years ago.

This causes more pressure on the physical body as the blood flows.

Fortunately, Lu Kun is a bone treasure stage level of physical cultivation, his physical body is strong, and his blood vessels are extremely tough, these pressures have no effect on him, but if it were other immortal cultivators, the blood vessels in his whole body would have already burst open, even if it was a low-level physical cultivation, he might not be able to withstand such a heavy blood.

At this time, Lu Kun's blood carried ten percent of the magic power of the Great Perfection level of foundation building, the power of qi and blood was surging, and the muscle magic power was at the level of the early stage of foundation building.

In his current situation, I am afraid that the blood demon sons of the previous generations of the Blood Refining Sect could not imagine that someone would be able to use the magic power cultivation in the early stage of foundation building to cultivate the secret technique of the blood demon skill to the terrifying realm of ten percent of the great perfection mana of foundation building.

Lu Kun felt the power of recovering half of his qi and blood, and muttered: "The power of qi and blood is restored, and the magic power of the arm can be used, but unfortunately there is no mana in the Dan period, and I don't know how powerful it is." ”

Clenched his fists, Lu Kun still gave up using his Divine Ability, he was in the Cave Mountain Range of the Foundation Building Period Monk of the Blood Refining Sect at this time, if he urged the Divine Skill of the Divine Arm and revealed the aura of the Formation Stage, it would be troublesome to be sensed by the Formation Stage Monk who was in charge.

"Could it be that I have to find a way to get the Blood Demon Gong Formation Pill Technique?" Lu Kun muttered.

According to the realm, even if other blood devils have cultivated to the third level of the Great Perfection of the Blood Demon Skill, they can't compare to the blood magic power in his body.

And when the blood devil reaches this realm, he will burn the essence blood for the third time, cooperate with many auxiliary pills and methods, and begin to condense the golden pill, and after entering the pill period, he will go to the blood demon cave again to obtain the exercises of the blood demon gong pill period.

At that time, by cultivating the Blood Demon Skill's Dan Stage Exercises, they would be able to upgrade the magic power in their blood to the level of the Dan Stage.

But Lu Kun's current external cultivation is only in the early stage of foundation building, and it is impossible to enter the Blood Demon Cave, and if his blood magic realm is discovered, he will definitely be caught and studied by the old monster in the infancy of the door.

It took two years to cultivate to the Great Perfection of Foundation Building, which is too amazing.

Lu Kun slowly reined in the power of qi and blood, looked at the silver iron box on the side, there was not much black gravel left inside, and couldn't help but show a contemplative look: "Is it still related to demonic qi?"

When Lu Kun cultivated muscle magic before, the intensity of the demonic energy in the Blood Demon Mountain Range could not allow him to generate muscle magic, but now his blood magic power has reached the Great Perfection of Foundation Building.

Isn't it more demanding for demonic energy?

The more Lu Kun thought about it, the more likely it became.

"Hundreds of magic stones, which have been consumed almost in the past two years, it seems that we will find a way to get some more. ”

Magic stones are hard to find for other demon cultivators, and only after the appearance of the one-yuan secret realm can they obtain a large number of magic stones in it.

But for Lu Kun, he had another place to obtain the magic stone, and there was also the source of the essence of the demonic qi such as the true demon pool water.

That's the Dead Sea Devil's Cave.

A few years ago, after Lu Kun and the others escaped, the forbidden token in his hand could still be used four times, and he could go over again.

Thinking of this, Lu Kun simply cleaned up the clutter in the Lower Cave Mansion, emitted the muscle magic in his body, and left the Cave Mansion.
