Tenth-Level Natal Soul Tool, Ghostly Frost Flame

Valley camp.

Inside the newly constructed cultivation chamber.

Two Xia Yus sat cross-legged facing each other.

One of them was dark purple and semi-transparent, surrounded by chilling deathly ghost aura. It was the origin projection of Xia Yu's Ghost Martial Soul.

To forge Divine Sword Ghost Moon into a Tenth-Level Natal Soul Tool, Xia Yu had truly gone all out this time.

He had pushed the origin of his Ghost Martial Soul to its limit. Otherwise, it could not have manifested a projection.

Xia Yu spread his hands over his knees, supporting Divine Sword Ghost Moon in the air as soul power surged from his body and continuously poured into Ghost Moon like floodwaters released from a dam.

At this moment, Divine Sword Ghost Moon seemed as if it were about to melt beneath the tempering of soul power.

Although it still retained its overall shape, its entire body had already become a semi-transparent liquid.

Xia Yu remained utterly calm, unmoved, and did not pause the flow of soul power from his hands for even a moment.

Only occasionally did he divide a portion of his focus, multitasking as he urged forth the origin projection of the Ghost Martial Soul and infused the Martial Soul Origin into Divine Sword Ghost Moon.

This process continued for several days.

After the Martial Soul Origin fused into it, the aura radiating from Ghost Moon grew increasingly powerful.

It also underwent certain unusual changes, producing deathly ghost aura that shared the same origin as the Ghost Martial Soul.

At first, there was too little deathly ghost aura to reveal anything unusual.

But as time passed, more and more deathly ghost aura accumulated, and compression, friction, and other changes inevitably began to occur.

Finally, once the deathly ghost aura had been compressed to a certain limit, the slightest friction caused it to ignite like flames, giving birth to a ghostly blue frost flame that radiated endless chill.

"This... was truly unexpected!"

Xia Yu looked at the ghostly blue frost flame blazing fiercely along Ghost Moon's blade, a flash of shock crossing his eyes.

He had never paid much attention to the deathly ghost aura that came with the Ghost Martial Soul, always allowing it to grow alongside the martial soul.

His attitude had been simple: as long as it worked, that was enough.

He had never specifically studied that deathly ghost aura.

Of course, it was not that Xia Yu failed to see its power. He simply had not had much time before to balance researching and exploring the abilities of the deathly ghost aura.

To be honest, he found this deathly ghost aura quite handy.

But because he had to focus on cultivating spiritual power and researching soul tools, he had been forced to make choices.

Without any surprise, deathly ghost aura had been the one temporarily cast aside.

But that had been before. Now, Xia Yu felt it was necessary to pick deathly ghost aura back up.

This was because he had discovered that the frost flame born from the compression and friction of deathly ghost aura was not inferior to Ultimate Ice in the slightest.

It even possessed certain traits that Ultimate Ice lacked.

What was this? This was practically a treasure waiting to be developed.

How could Xia Yu possibly let such a treasure slip away?

"Since this frost flame was born from the deathly ghost aura that comes with the Ghost Martial Soul, I'll call it Ghostly Frost Flame."

After examining it and confirming that Ghostly Frost Flame would not affect the process of fusing the origin, Xia Yu stopped paying attention to it and continued the fusion process.

Once the Martial Soul Origin had completely fused, Ghost Moon changed in appearance as well.

First, Ghost Moon completely shed its ancient, unadorned form. Its entire body became semi-transparent, without the slightest metallic texture remaining.

Second were the silver moon patterns on Ghost Moon, which had originally represented soul tool formations.

Now, these patterns changed accordingly, gaining additional markings shaped like cloud-like flames.

Yet these new cloud-flame markings did not seem out of place. Instead, they complemented the original silver moon patterns, as though they had always been meant to be there.

The final change was that, after its transformation, Ghost Moon completely concealed its sharp edge.

At this moment, it looked more like an exquisite work of art, naturally formed and incomparably beautiful.

Rather than a weapon, much less a Tenth-Level Soul Tool...

In short, Ghost Moon now appeared completely nonthreatening.

Yet it contained power capable of destroying heaven and earth. Once drawn, it would surely shake the world and stun all who saw it.

Clang!!!

Xia Yu reached out, picked up Ghost Moon, and lightly flicked the blade with his finger.

A crisp sword cry immediately rang out, clear and melodious, lingering without end.

"Not bad. A fine sword. From now on, follow me as I roam the world!"

As if it had heard Xia Yu's words, Ghost Moon trembled lightly in his hand.

Then Xia Yu felt an incomparably pure stream of soul power flow from Ghost Moon into his body. After circulating through his body once, it returned to Ghost Moon.

Back and forth it flowed, cycling without end. From then on, a complete circulation was formed, endlessly renewing itself.

Buzz!!!

Thanks to the endlessly circulating loop of soul power between himself and Ghost Moon, Xia Yu's cultivation was actually stirred into motion and began to rise slowly.

Xia Yu's soul power had already reached the peak of level ninety-five. With this increase, was he not heading straight for a breakthrough?

As Xia Yu entered the breakthrough process, Ghost Moon immediately underwent corresponding changes, and the soul power pouring in became even more abundant.

With the help of Ghost Moon, this Tenth-Level Natal Soul Tool, together with all the advantages Xia Yu himself possessed, this breakthrough proceeded without any surprises.

In less than half a day, Xia Yu's soul power naturally rose to level ninety-six.

"Phew... It's time to come out of seclusion."

After stabilizing his soul power, Xia Yu put away Ghost Moon.

Without any visible movement from him, Ghost Moon was absorbed into his body and entered his Mental Sea of Consciousness.

As soon as it appeared, Ghost Moon imitated the Gold of Life in the Second Sea of Consciousness, rising into the sky above the Mental Sea of Consciousness and transforming into a bright moon that cast down ghostly blue radiance.

Then, beneath Ghost Moon's illumination, Xia Yu's Mental Sea of Consciousness burst into blazing Ghostly Frost Flame and transformed into an endless sea of fire.

"Well, now both of my seas of consciousness are seas."

Xia Yu did not try to stop the burning Mental Sea of Consciousness.

Though Ghostly Frost Flame burned fiercely, it did not harm the Mental Sea of Consciousness.

On the contrary, as the sea of fire spread, Xia Yu could clearly feel his Mental Sea of Consciousness becoming sturdier.

Although the change was faint, it would become considerable over time.

As for why he said both of his seas of consciousness had become seas, it was because the Second Sea of Consciousness had also developed an emerald Sea of Life under the influence of the Gold of Life.

Now, of Xia Yu's two seas of consciousness, one was a ghostly blue sea of fire representing death, while the other was an emerald ocean representing life.

The two complemented and restrained each other, benefiting one another in perfect harmony.

Sure enough, once the ghostly blue sea of fire had fully taken shape, the two seas of consciousness began to resonate with each other.

As their auras circulated, they not only promoted each other's growth and stability, but also gradually became alike, showing signs of merging into a single whole.

Once the two seas of consciousness became one, it would undoubtedly be another tremendous stroke of fortune.
