Spirit-Eating Engraving Knife, Demon Seed in the Soul Bone

Elder Chi Xiao's discovery was extremely important.

All the Body Sect disciples present realized this.

As practitioners of Body Martial Souls, they naturally knew the advantage of their own Martial Souls: an unceasing mechanism of Positive Feedback.

As long as the mechanism remained unchanged, it would forever be tier zero.

If this mechanism could be incorporated into Bloodline Power refinement, the Bloodline Furnace Method's efficiency in refining Bloodline Power would inevitably improve drastically.

Moreover, this concept could still be applied in future Bloodline Power cultivation.

In the past, everyone understood this mechanism, but had merely enjoyed its benefits passively. Elder Chi Xiao had also benefited from it passively.

However, after Elder Chi Xiao shared this discovery, the Body Sect members realized that this mechanism could also be actively applied to cultivation.

After Elder Chi Xiao finished sharing, the elders and disciples stirred up another small wave of enthusiasm for refining Bloodline Power.

Mu Yuan did not immediately explore this so-called Positive Feedback cultivation. Instead, he followed his original plan and began the next stage of his cultivation.

"Spirit-Eating Engraving Knife."

Du Busi looked at the engraving knife in his hand, which radiated an icy, sinister aura, his expression rather grave.

"Mu Yuan, are you sure you can control this engraving knife?"

The moment one touched the engraving knife, the icy aura within would invade the body. Du Busi felt that if his cultivation had not been so profound, he likely would not have been able to hold it continuously.

Yes, merely holding it allowed the icy power to invade one's body.

His cultivation was profound enough that he could refine this icy power at all times, but ordinary Soul Masters could not.

By his estimation, if a Soul Master below the Soul Emperor rank was invaded by the icy power, they might not even have time to react before their Meridians were damaged.

Mu Yuan said, "Sect Master, I possess Bloodline Power and have fused Vajra Power with Heavenly Thunder Power, two supremely yang and unyielding forces. They are the greatest counter to such yin and evil power."

As he spoke, he had already extended his hand.

Du Busi handed over the Spirit-Eating Engraving Knife.

He stared closely at Mu Yuan. The moment Mu Yuan encountered trouble, he would immediately snatch back the Spirit-Eating Engraving Knife and prevent more icy power from entering Mu Yuan's body.

The reality was far better than he had imagined.

Mu Yuan's hand touched the Spirit-Eating Engraving Knife, and the icy power instantly invaded his body.

However, surging Bloodline Power immediately flooded into his right hand.

The Scarlet Spirit Bone was also exerting its power.

At his right arm, Mu Yuan's control over his Bloodline Power was at its strongest.

Vajra Power and Heavenly Thunder Power—two supremely yang and unyielding forces, one fused into his bloodline and the other mingled within it—instantly shattered the icy power.

Yet it was only shattered. Mu Yuan had not completely refined the icy power. It was exceedingly stubborn and, following the flow of his bloodline, spread throughout the Meridians of his entire body in the blink of an eye.

Mu Yuan did not panic.

He did not even release the Spirit-Eating Engraving Knife in his hand.

The icy power continuously invaded his body.

Carrying Vajra Power and Heavenly Thunder Power, Mu Yuan mobilized his bloodline, continuously shattering the icy power before deliberately guiding it to every part of his body.

Yellow, purple, purple.

Three Soul Rings emerged in succession, and the first yellow Soul Ring shone brilliantly.

"First Soul Skill, Diamond Demon Body!"

The Demonic Qi that Mu Yuan could deliberately restrain began to grow.

It intertwined with Vajra Power. Strangely, due to its fusion with Vajra Power, when it was transformed, it directly entered a state of mingling with his bloodline.

A smile appeared on Mu Yuan's face.

This was an effect he had cultivated long ago.

It was precisely because of this that he had begun this stage of cultivation.

"Bloodline Furnace, refine!"

His bloodline roiled and roared within him, washing over every inch of flesh in his body.

Perhaps because of the Heavenly Thunder Power within it, Mu Yuan heard bursts of thunder as his bloodline churned.

Seeing Mu Yuan enter the Bloodline Furnace state, Du Busi breathed a sigh of relief.

Before cultivating, Mu Yuan had explained the steps to him. Now that he saw Mu Yuan operating the Bloodline Furnace Method, he naturally knew that the cultivation had entered the proper course.

Du Busi took the Spirit-Eating Engraving Knife from Mu Yuan's hand, placed it in a box that radiated a bright aura, then stored it in his Storage Soul Guidance Device.

Du Busi sat opposite Mu Yuan and waited quietly.

Guiding his bloodline and turning it into a furnace, Mu Yuan refined the icy power from the Spirit-Eating Engraving Knife with all his strength.

This icy power was not an ice-element power, but a cold and Evil force containing resentment and blood fiend power. It was exceedingly strange.

Mu Yuan fused Demonic Qi into his bloodline and used the Bloodline Furnace to smelt the icy power. In doing so, he was using the power of that icy force to nourish his Demonic Qi.

As he guided his bloodline, Mu Yuan thought of the experience Elder Chi Xiao had shared and consciously began communicating with his own Martial Soul while operating the Bloodline Furnace.

The moment he established that connection, he felt a difference.

The circulation of bloodline in his arms naturally became more complex, and both his arms and Bloodline Power were strengthened.

At the same time, the Scarlet Spirit Bone in Mu Yuan's right arm faintly stirred.

"Heh. As expected of an Evil Secret Technique Soul Bone created by an Evil Soul Master. Upon encountering this yin and evil power, it immediately feels like it wants to fuse with it."

Mu Yuan suppressed it.

He had specifically reserved this power to feed his own Demonic Qi.

Demonic Qi had no roots. In the end, he could still incorporate it into the Scarlet Spirit Bone.

Time passed.

After the icy power within his body had been completely smelted by Mu Yuan, his Demonic Qi was still suppressed by Vajra Power and Heavenly Thunder Power, but it had already far surpassed Vajra Power alone.

Mu Yuan infused Soul Power into the Scarlet Spirit Bone. That sensation of fusion remained, and he immediately circulated his Demonic Qi and poured it into the Scarlet Spirit Bone.

After all the Demonic Qi had been compressed into the Soul Bone, it seemed that the characteristics of the icy power were still taking effect, as it began to settle within the Soul Bone.

Sensing this, Mu Yuan immediately poured Bloodline Power into the Soul Bone again, condensing the Demonic Qi together.

Rather than letting it settle throughout the Soul Bone, it was better to condense it into a single seed.

This was—

"Demon Seed!"

After completing all this, Mu Yuan slowly opened his eyes.

"Sect Master, everything went smoothly."

Du Busi breathed a sigh of relief.

"Looking at it this way, the Spirit-Eating Engraving Knife has become cultivation nourishment in your hands instead." He smiled.

Mu Yuan nodded.

It was not just this yin and evil power.

Once he had absorbed all the icy power on the exterior of the Spirit-Eating Engraving Knife, the true core within it—Life Gold—would continue to shine.

After seeing Du Busi off, Mu Yuan took out the Spirit-Eating Engraving Knife once more.

After absorbing another portion of icy power and putting away the engraving knife, he closed his eyes and began refining again. In the end, he gathered the Demonic Qi into the Scarlet Spirit Bone, strengthening that Demon Seed.

During this time, he also tried mobilizing the Demon Seed's power. Combined with the First Soul Skill, Diamond Demon Body, the Demonic Qi he could unleash directly surpassed Vajra Power. He had to use Heavenly Thunder Power alongside it to suppress the Demonic Qi.

Without mobilizing the Demon Seed's power, however, his Diamond Demon Body remained in a balanced state.

"Continue familiarizing myself with the Spirit-Eating Engraving Knife's power. The next goal is to reach the Life Gold within it."
