The probability of a Spirit Beast producing a Spirit Bone is extremely low.
It is so low that even after ten thousand years, Spirit Bones remain a scarce resource, and most Spirit Masters rarely see one in their entire lives.
However, the drop rate of Spirit Bones is not entirely beyond human interference.
The secret technique soul bone is one such method, but reckless slaughter is considered an evil path in this day and age; after all, the conflict between Spirit Masters and Spirit Beasts has already accumulated too much.
Besides the secret technique soul bone, another way is to let the Spirit Beast experience extreme emotional fluctuations before death—hatred or satisfaction—which is said to increase the probability of a Spirit Bone dropping.
It is still not a one hundred percent guarantee that a Spirit Bone will drop.
But there is no doubt that the fact this theory has been passed down implies it has a certain degree of rationality.
It is not difficult to accept that extreme emotions imbue a powerful will, which has some connection to the condensation of a Spirit Bone.
Upon noticing the emotions of hatred and pleading intertwined in the eyes of the Deep Sea Demon Octopus, Mu Yuan could not help but think of these things.
He subconsciously glanced at Du Busi.
For the past half month, the piercing cries of the Deep Sea Demon Octopus have often echoed on the small island.
So, Du Busi was doing it on purpose.
He was not cruel by nature, nor was he just having fun; he purely sensed that this Deep Sea Demon Octopus had the potential to condense a Spirit Bone, and since its hatred for the two of them had reached a certain level, he was simply acting accordingly.
“Thank you, Sect Master.”
Although a Spirit Bone had not yet dropped, Mu Yuan was still grateful that the other party had considered his spirit ring so thoroughly.
Du Busi waved his hand, not caring at all.
In his eyes, there were only his family from the Body Sect.
Since Mu Yuan was a disciple of the Sect, he would do his best to help him.
It wasn’t that he went all out for every disciple, but his energy was limited, and most of the time he was really too lazy to act.
But since he had come out this time, these things were easy enough to handle, so naturally, he would not be negligent.
After expressing his gratitude, Mu Yuan looked at the Deep Sea Demon Octopus.
Taking a deep breath, a bright yellow spirit ring slowly rose from beneath his feet.
“First Spirit Ability, Vajra Demon Body!”
Mu Yuan’s body instantly expanded in size, and his arms were filled with muscles, with veins bulging like dragons coiled upon them.
“Vajra Demon Subduing!”
A dark golden flash crossed his eyes as Mu Yuan gathered his Vajra Power into his right arm.
A dark golden phantom condensed from his right arm.
Within his right arm, a scarlet light appeared, and a power intertwined with red and black surged forth.
Blood energy mixed with demonic energy rushed out, enveloping the phantom arm formed by the Vajra Power.
Boom!
He threw a punch.
The Deep Sea Demon Octopus was firmly restrained by Du Busi and could not resist at all.
It was not prepared to resist either.
He did not mobilize the Power of Heavenly Thunder.
It simply allowed this punch to slam into its head.
With the demonic energy as the guide and blood energy as the thread, the Vajra Power followed the trail, driving straight into the depths of the Deep Sea Demon Octopus’s body, crushing everything inside its brain in a devastating manner.
Bang!
Du Busi let go, and the body of the Deep Sea Demon Octopus fell to the ground.
A noble purple light gathered between heaven and earth.
Before long, a purple spirit ring appeared before Mu Yuan.
Without hesitation, Mu Yuan connected to the spirit ring with his Soul Power, sat cross-legged on the body of the Deep Sea Demon Octopus, and began to fuse with this spirit ring.
Du Busi scanned the body of the Deep Sea Demon Octopus.
Seeing no Spirit Bone, a trace of disappointment flashed in his eyes.
Was it all for nothing?
But the next moment, the disappointment in his eyes vanished, leaving only a hint of surprise.
He looked at Mu Yuan and discovered that Mu Yuan, who was currently fusing with the spirit ring, was unconsciously gathering the Soul Power that had dissipated after the death of the Deep Sea Demon Octopus.
That was Soul Power that did not belong to the spirit ring.
Behind Mu Yuan, at his shoulder blades, a pattern resembling a hexagonal compass was forming, faintly condensing something.
Du Busi walked around to Mu Yuan’s back, observed this scene carefully, and fell into deep thought.
…
Spirit World.
Mu Yuan sat cross-legged in a pitch-black World, with black and gold colors flowing through his arms.
If one looked closely, one would find a trace of blood color brewing within his right arm.
A Deep Sea Demon Octopus spread its eight tentacles, clinging tightly to his back.
Mu Yuan only felt as if his back was being frantically bitten by the Deep Sea Demon Octopus; the pain, akin to bones shattering and flesh tearing, went straight to his soul.
Just when Mu Yuan thought this was all, a surge of Power of Heavenly Thunder rushed into his body from his back.
Boom!
The Power of Heavenly Thunder raged, sweeping through his limbs and bones.
The demonic energy dissipated, hiding beneath the Vajra Power, and the blood energy vanished.
The Power of Heavenly Thunder reshaped Mu Yuan’s body, connecting his limbs and bones.
But this did not alleviate his pain; instead, it magnified his suffering.
The octopus on his back acted like a suction cup, its terrifying suction force seeming to want to devour all of Mu Yuan’s flesh and internal organs.
Mu Yuan gritted his teeth, holding fast to his mind.
His will was firm.
“Vajra Demon Subduing!”
In this World of endless darkness, a roar echoed.
Rumble!
Mu Yuan felt as if something was growing on his back, breaking out of its shell.
The Vajra Power and the Power of Heavenly Thunder mixed together, flowing throughout his body, eventually returning to his back and bursting out of his body with a bang.
…
By the time Mu Yuan woke up again, it was already evening.
Seeing this, Du Busi handed him a water flask.
“You kid, you’ve obtained a great opportunity this time.”
His eyes were filled with uncontrollable admiration.
Mu Yuan had no doubts; he had felt it during the process of fusing with the spirit ring—those limbs gushing forth from his back, as if newborn, must be a Spirit Bone.
Furthermore, it was not an ordinary Spirit Bone, but an external Spirit Bone.
It was a supreme treasure that Spirit Masters dreamed of.
In this era, hundred-thousand-year spirit rings and Spirit Bones were no longer legends; powerhouses like Du Busi, Mu En, and Long Xiaoyao all possessed more than one set.
Yet, none of them had an external Spirit Bone.
“From the perspective of the Body Martial Soul, your previous arm Spirit, viewed from the perspective of the human body, was both important and unimportant, but now your arms are no longer just arms.”
Du Busi looked at Mu Yuan, a trace of complexity flashing in his eyes, hidden with anticipation.
“The Deep Sea Demon Octopus provided you with a Spirit Bone, an external Spirit Bone, attached to your back and connected to your arm bones, shoulder blades, and ribs, as if they were one.”
“This external Spirit Bone of yours, using the Power of Heavenly Thunder and Vajra Power, has condensed six additional arms, which, combined with your original pair of arms, makes for eight arms.”
Du Busi’s face was filled with amazement.
“With the help of this Spirit Bone, the body parts corresponding to your arms are no longer purely just your two arms; I feel that if you continue to cultivate, your back and even your entire torso may become part of your Spirit.”
Arms are not important?
The more arms you have, the wider the area of the human body that corresponds to them.
Du Busi could only say that Mu Yuan had provided a new train of thought for the cultivation of the Body Martial Soul in the Body Sect.
“Perhaps, I can also give it a try…”
Extending the arm expansion to include the torso.
Without a doubt, Mu Yuan’s Spirit had taken a huge step forward.
Du Busi’s own Spirit was the body; it seemed complete, but in reality, it was not.
His body only corresponded to the physical form and had not yet covered the soul.
“If I can encompass the soul with my Body Martial Soul and truly make the Spirit complete, then the condensation of the second Spirit core will be but a single thought away!”
