The room of the spire was a mess, littered with materials and black debris, and the forbidden light curtains on the walls were dim.

A dignified woman with a cold aura suddenly appeared outside the room, but after seeing that the people inside were safe and sound, she disappeared into the air.

Lu Kun looked at his palm blankly, the newly refined Rongyuan Demon Ball had disappeared, and at the same time, the flesh and blood on its palm were also wiped out, revealing a white jade-like hand bone.

In addition, there were tiny holes on his skin, and with the power of qi and blood surging, small pieces of gravel were repelled from his skin and fell to the ground.

These gravels are the materials that make up the dense layer of bone.

Dugu Feng looked at the devastated scene and the scars on Lu Kun's body, and couldn't help but sweat coldly, if it wasn't for Lu Kun standing in front of him just now, he was defenseless, and this thin body would probably be destroyed.

Dugu Feng swallowed a mouthful of foam and said with difficulty: "Pavilion Master, isn't what you are refining a recovery magic weapon......

Lu Kun didn't seem to hear Dugu Feng's words, he muttered: "Impossible, the structure of the bone cancellous has been perfected, the characteristics of the Rongyuan magic stone are evenly distributed, and the magic energy is very stable. ”

"Why is it that when I absorb demonic energy, such a terrifying destructive power erupts, much more powerful than the destructive power of the cultivation state. ”

Not long ago, the Rongyuan Demon Ball was successfully refined, and Lu Kun tried to absorb the demonic energy stored inside, but who knew that his actions directly ignited the demonic energy and erupted with such a surging destructive power.

After thinking for a moment, Lu Kun said in a deep voice: "Brother Dugu, restore the mana, and we will continue refining." ”

"But, the Pavilion Master ......"

Before Dugu Feng finished speaking, he was interrupted by Lu Kun: "Don't worry, you are behind me next, and I will stand in the way of any situation." ”

When Dugu Feng heard this, he immediately closed his mouth and honestly recovered his mana.

......

A few days later, the same gray ball appeared in mid-air, and Dugu Feng was wearing a thick mana shield and carefully hiding behind Lu Kun.

Lu Kun's eyes flashed with dazzling golden light, urging the golden eye divine power to the extreme, carefully observing the situation inside the Rongyuan Demon Ball.

It took a full day for him to put away his supernatural powers and fall into deep thought.

Under the cooperation of the essence and blood in the Rongyuan Demon Ball, Lu Kun found that the magic energy stored in it was very stable, and it was the same as ordinary mana, staying in it honestly, and the energy storage array and the Yuan Spirit Array, as well as the characteristics of the Rongyuan Demon Stone, all played a great role.

But as time passed, he gradually sensed that under this calm, there was a destructive power that had been suppressed to the extreme.

Since there is no life force, after the magic energy is separated from the body, it will turn into a mixed and intertwined state of chaotic mana and magic power, producing the power of destruction.

The reason why magic energy can damage the magic weapon of an immortal cultivator is because this destructive power contained in the energy can enter the magic weapon and destroy it.

The magic energy in the Rongyuan magic ball is also a mixed and intertwined state of mana and magic power, and due to the honeycomb structure of the bone cancellous, the contact between mana and magic is more sufficient, and the power of destruction is more powerful.

The Fusion Yuan Magic Ball has extremely strong stability and compatibility, and although the destructive power contained in the magic energy is strong, it cannot burst out and has been suppressed.

Under Lu Kun's observation, the destructive power that his half-immortal demon could carry had accumulated to its limit in a quarter of an hour.

His previous action of absorbing magic energy directly and completely disrupted the stable structure inside, causing the power of destruction, like a volcanic eruption, to erupt rapidly.

If he uses the blood control technique to attract the essence blood inside, he will also burst out this destructive force.

"Pavilion Master, has this refining also failed?" Dugu Feng couldn't help but ask when he saw Lu Kun put away his spiritual powers.

Lu Kun sighed and said, "This way, although it can store magic energy, it can't absorb it, so it's a failure." ”

He looked at the quiet gray ball in his hand, and his eyes showed a bit of strangeness: "But this Rongyuan magic ball can be used as a one-time self-detonation magic weapon." ”

Lu Kun pondered for a moment and said, "The power of this self-detonation magic weapon is at most equivalent to the peak of the early stage of the Yuan Infant, and it doesn't help me much. ”

"Although only my essence blood can be controlled remotely, with another layer of control, the essence blood of other body cultivation disciples may not be able to activate it......

Dugu Feng recalled the explosive power a few days ago, and said dumbfounded: "That is to say, any physical cultivation disciple, as long as he has this magic ball in his hand, has a chance to kill the early stage of the Yuan Infant!"

Lu Kun shook his head and said: "Brother Dugu is too simple, the Rongyuan Demon Ball contains half of my magic energy and essence blood, and others want precise control, it's not that simple." ”

As he spoke, his huge divine sense came out of his body, and a shadow flashed outside the room, and then Lu Kun asked Dugu Feng to sacrifice the Yuanying True Fire again.

Lu Kun's idea was very direct, since the explosive power of the Rongyuan Demon Ball was so powerful and could be controlled through his essence blood, then he could simply refine it into a self-detonation magic weapon that other body cultivators could control.

If you want other body exercises to be controlled, you need to be stable and controllable.

In the previous design, the Rongyuan Magic Ball was divided into two layers, namely the bone cancellous material that stored the magic energy inside, and the bone dense shell that depicted the miniature magic circle.

With the protection of the dense shell of bones, disciples below the bone metamorphosis stage can hardly communicate with the magic energy inside, so they need to add a layer of essence and blood medium.

With the calcination of the Yuan Infant Fire, Lu Kun used his own essence blood to outline a capillary network on the surface of the softened bone compact.

A few hours later, a magic ball densely covered with vascular lines appeared in mid-air, and a drop of silver blood swam in the blood vessels, appearing very agile.

Lu Kun sensed it and nodded slightly, as long as the others could stimulate this drop of his essence blood inside, they would be able to stimulate the power of destruction within the Rongyuan Demon Ball.

After observing for a while, Lu Kun sighed lightly: "The teleportation circle is really convenient, this kid Qingtian has already come." ”

With a movement of his divine sense, he opened the ban on the spire, and Zhao Qingtian was suspended in mid-air with a cyan power suit, looking extremely capable.

"I've seen Shizun, I've seen Elder Dugu. ”

Lu Kun said: "Qingtian, come in, call you over, it's to test a self-detonating magic weapon, to see if you can use your essence blood to urge it." ”

Zhao Qingtian was slightly stunned, and then looked at the center of the room, the gray ball that exuded a rich power of qi and blood, and was densely covered with a network of blood vessels, and he said curiously: "Master, what is the disciple going to do." ”

"It's very simple, Brother Dugu and I will refine a layer of structure similar to periosteum outside this magic ball, and you have to manipulate your essence and blood, and construct a vascular network in my way. ”

"Yes, Master. ”

Next, Lu Kun took out the gray material of the demon bone as a periosteal layer, wrapped around the bone dense, and at the same time, Zhao Qingtian stimulated a cloud of pale cyan essence blood and submerged into it.

After the study of the spirit root, Lu Kun integrated the way of blood control into the technique of cultivating the body and cultivating the weapon, and under the study of a generation of disciples, his proficiency in the essence blood refining weapon has greatly increased.

After a while, Zhao Qingtian constructed a layer of pale cyan blood light network in the new periosteal layer, echoing Lu Kun's network inside.

At this time, the Rongyuan Demon Ball turned into a gray ball full of cyan blood vessels, mixed with essence blood and magic energy, and the aura looked very strange.

Zhao Qingtian pondered for a moment and said, "Master, the network you asked me to construct seems to be transporting essence blood to the inner layer?"

Lu Kun nodded and said, "That's right, Qingtian, you now activate thirty percent of the essence blood in your body and transport it into this Rongyuan magic ball to see if you can activate the drop of essence blood that I have stored in the middle bone dense layer." ”

"Yes, Master. ”

Zhao Qingtian patted his chest, and under the operation of his heart, he spit out a rich ball of cyan essence blood, exuding a not weak power of qi and blood, wrapping the gray ball and infiltrating it along the network he constructed.

Lu Kun's body moved, blocking Zhao Qingtian and Dugu Feng behind him.

After a long time, Zhao Qingtian's face turned pale, sweat was on his forehead, and he said with a wry smile: "Master, your essence blood is too strong, with the strength of Qingtian's essence blood, it is like a grasshopper shaking a tree, and it can't be moved in the slightest." ”

Lu Kun's eyes flashed with gold, and he said thoughtfully: "It seems that you have to wait until you reach the middle stage of the bone treasure, the blood magic power has reached the early stage of the knot, the blood density has increased greatly, and then you can stimulate fifty percent of the essence blood, and then you can urge it, and when you reach the great completion of the bone treasure, you can get three percent of the essence blood." ”

Zhao Qingtian was extremely curious and said, "Master, what kind of magic weapon is this, it needs such a strong essence blood to urge." ”

Lu Kun chuckled, he opened the prohibition of the room, and with a flick of his arm, the Rongyuan Demon Ball shot into the air like gray lightning under his terrifying power, and then he mentally communicated the essence and blood inside.

"Boom!"

A burst of silver light erupted in the sky, and the terrifying destructive power exploded, and the clouds in the sky were blasted open a large gap, and the surging aura clouds rolled outward.

Dugu Feng looked at the sky from afar, revealing a hint of palpitation: "The pavilion master is right, the power of this self-detonating magic weapon is comparable to the peak of the early Yuan Infant. ”

Zhao Qingtian opened his mouth wide and said with a dull expression: "Master, you mean, when I reach the middle stage of the bone treasure, I can urge this self-detonation magic weapon?"

Lu Kun nodded, his expression was also a little excited, although the refining of the recovery treasure failed, but refining a self-detonating magic weapon like the Rongyuan Demon Ball was also not small.

What made him feel excited was that this treasure was completely detached from the traditional magic weapon system of cultivating immortals.

It is made of bone transformation period body cultivation, with the help of the magic energy in the body refining, with essence blood as the trigger medium, rather than the mana of traditional immortal cultivators, if the bone treasure mid-stage body cultivation has this treasure in hand, with the power of the body, it also has a great deterrent effect on the Yuan Infant Stage!

"It's a pity, the raw materials are scarce, the seventh-level demon bones are too wasteful, if you use the sixth-level demon bones to refine, the stored demonic energy will be less, and the power should not be weaker than the early stage of the Yuanying. ”

"This self-detonating magic weapon is called the Ball of Destruction. ”
