Three months later, Lu Kun's figure appeared outside the Blood Demon Mountain Range, and there was still more than half a year before the opening of the One-Yuan Secret Realm, as a Blood Demon Son, he had to return to the Blood Refining Sect and enter the One-Yuan Secret Realm on time, otherwise he would be dealt with as a traitor.

The so-called traitorous treatment, that is, using the stone of oath to directly kill the soul.

Although Lu Kun was quite confident that his divine soul would be able to hide his supernatural powers and avoid the Stone of Oaths, he was unwilling to expose his supernatural powers so early.

The identity of the Blood Demon is even more precious to him now.

After Lu Kun entered the middle stage of the bone treasure, the blood magic power crystallization of the previous foundation building great perfection did not play a big role, as long as the blood magic power was released in the bones, it would be immediately wiped out by the thunder attribute mana in the middle stage of the knot.

When the thunder attribute mana is too strong, the annihilation power emitted by the two energies is much less, and with the bones of the current magic weapon level, this energy has no refining effect at all.

Therefore, Lu Kun had to covet the Blood Demon Skill of the Blood Refining Sect during the Dan Period, trying to perfect the higher-level cultivation method of the Blood Demon Bone Alchemy Technique.

The cultivation of the bone treasure from the middle stage onwards is like an ordinary immortal cultivator's magic weapon, constantly using mana to conceive and nourish it, so that its power gradually increases.

As for to what extent it will enter the late stage of the Bone Treasure, Lu Kun has already guessed in his heart according to the refining classics left in the Yueyang Sect.

The bone treasure is equivalent to the magic weapon, the natal magic weapon of the monks in the Dan period, and there are two stages.

The newly refined magic weapon, after being cultivated into the body by the monks of the Dan period, will be slowly conceived by the mana of the Dan period, and the power will be significantly different because of the number of years of pregnancy.

Normally, the magic weapon that has been conceived in the body for more than three hundred years, the power has made a breakthrough, and in the refining classics inherited by Yueyang Sect, a very appropriate term is used to describe this kind of magic weapon, that is, the magic weapon of the maturity period.

At that time, the elder of Yueyang Sect's refining instrument peak, Ling Huyi, Gu Tianjian's master, although he only had the cultivation of the early stage of the Jiedan, but he had carefully tempered the natal magic weapon for more than three hundred years, and his power was strong.

Therefore, Ling Hu Yi was able to block the three late-stage powerhouses of the Yudan stage alone in a short period of time, and buy time for Lu Kun and them to escape, relying on the power of the magic weapon of the maturity stage.

The longevity of the monks in the Dan period is about 500 years, and when they enter the Dan period, the average immortal cultivator is often around 150 years old.

Most of the strong people in the late stage of the knot are about four hundred years old, and they have spent a lot of time cultivating mana, and the magic weapons are often not refined to more than three hundred years, and the magic weapons in the mature stage are very rare among the monks in the knot stage.

There are only the magic weapons of the old monsters in the Yuan Infant Stage, all of which have been tempered for more than three hundred years, and they are the magic weapons of the mature stage, and with the advanced mana of the Yuan Infant Stage, they can exert the power that makes the monks of the Yudan Stage despair.

Lu Kun speculated that the realm of the late stage of the bone treasure was to refine the magic weapon in the body to this state of maturity.

But he has a lot of bone treasures, there are more than two hundred pieces, if he is tempered normally, he will have run out of life and die a long time ago, so he can only hope for the Blood Demon Bone Alchemy, the Blood Demon Sect's Blood Demon Technique of the Dan Period, he must find a way to get it as soon as possible.

......

Lu Kun revealed the magic of the early stage of foundation building, first went to the mission hall of the core mountain gate, handed in a few tasks, and then returned to the western cave mountain range and entered his own cave in the Blood Refining Sect.

Before he returned to Qi State, he had already consumed all the thunder attribute mana in the middle stage of the knot pill in his body, stored the blood magic power crystals in his bones, and only one of the magic power of building the foundation of the Great Perfection was left in his blood, reducing the power of qi and blood to a minimum.

Now Lu Kun has entered the middle stage of the bone treasure, and the bones of the whole body have become a magic weapon.

Although carefully hidden, the monks of the same level may not be able to perceive his mana, but he has just entered the middle stage of the bone treasure, the bone treasure is not yet fully familiar, if the mana is occasionally stirred, there will be a faint treasure in the body, if there is a strong sense of divine consciousness or the existence of special magical powers, it may not be able to detect the special features of his bones.

Especially in the Blood Refining Sect, a sect with more than 30 monks in the Dan Stage and more than 10 monks in the Yuan Infant Stage, he only felt more at ease when he had exhausted all the mana in the Bone Treasure.

After he completely uses the bone treasure in his body, he will be able to control the bone treasure qi well, and it will be safe at that time.

As soon as Lu Kun entered the cave, he found that in the forbidden aura in the cave, there were many transmission notes and jade slips flashing, and there were even two storage bags.

A magical light flashed in his hand, opening the notes one by one.

"Senior Brother Zhang, thanks to the last rescue, Fang sent some intermediate talisman materials to express his gratitude. ”

"Although I Lei think very highly of myself, but the grace of my junior brother to save me must also be replaced, Lei Mou, like that guy from the Fang family, also gave my junior brother some talisman materials. ”

"Brother Zhang, I'm Xu Zihang, the secret realm of one yuan is about to open, I want to find a time to chat with Brother Zhang. ”

"Senior Brother Zhang, in Xia Feng Xuefeng, I have heard the name of Senior Brother for a long time, I don't know if I can appreciate my face, go to the cave mansion and talk about it, and I will be in the lower cave mansion ......"

"Senior Brother Zhang, contemptible Yu Feibai, the task of killing the three waves of the Demon Cultivator Crazy Knife in the door is a bit difficult, I don't know if the junior brother can help, the contribution points are distributed fairly, if the junior brother agrees, ...... it"

"Senior Brother Zhang, Senior Sister Mu Le'er has admired her for a long time, not only does Senior Brother have a double cultivator, but Senior Sister's cave location and physiognomy album are all in the Jade Jane, Senior Brother can come over at any time!"

......

The first two were Fang Hao and Lei Batian's transmission notes, which seemed to be to thank him for saving him, Lu Kun's divine sense swept the two storage bags suspended outside, and he couldn't help but show a hint of surprise, the materials placed inside were more than he imagined, enough to refine thirty or forty intermediate and beginner-level magic thunder talismans.

"These two guys, giving so many talismans, seem to want to befriend me. ”

He casually threw aside the storage bag full of talisman materials, held Xu Zihang's transmission note in his hand, and said to himself: "According to the importance of Xu Zihang in the door, he must know that I am a blood devil, and he is looking for me alone, because he wants to join forces with me in the realm of the One Yuan Secret?"

The other transmission notes are all disciples of the foundation building period in the door who want to make friends with Lu Kun, after all, Lu Kun's reputation is not low now, and it is rumored in the scattered cultivation that he has a combat power close to the late stage of foundation building.

There are also jade slips of many female disciples, Lu Kun took a closer look at them, and then threw them aside.

"Hey, what?" Suddenly, another amazing transmission note flew from outside the cave.

Lu Kun opened it with his hand, and a rather familiar voice came from inside: "Zhang Yiyang, in two months, come to the meeting hall of the core sect, the one-yuan secret realm is about to open, and the elders in the gate will assign tasks to you." ”

As soon as Lu Kun recognized it slightly, he knew that this was a monk surnamed Rong surnamed Yudan who was sitting in the entrance hall, this person was a disciple of Elder Qian in the door, and the reward that the blood demon son should have last time was sent by him.

"In two months' time, the Council Hall? In this way, the Blood Refining Sect will gather all the disciples who have entered the One Yuan Secret Realm, and I am afraid that the other Blood Demon Sons will also show up one by one. ”

Lu Kun touched his chin and thought.
