"Buzz—Buzz—Buzz—"

However, upon hearing Lin Yun's words, the Bloodthirsty Sword vibrated even more violently. The crimson glow on it flickered rapidly, weakening and strengthening alternately as a series of light whimpers arose, as if it was speaking.

In fact, it was indeed speaking, only it was communicating with Little White and Little Blue…

"Brother, Little Blood says it can help you refine these forces, allowing you to absorb them more quickly?" Soon, the three orbs stopped chasing each other within the Bloodthirsty Sword, and Little White spoke hesitantly.

"What?"

Lin Yun had been planning to stow away the Bloodthirsty Sword, but upon hearing Little White's transmitted message, he couldn't help but exclaim in surprise.

The Bloodthirsty Sword could actually help him refine that Spiritual Energy, allowing him to absorb it more quickly? This… This was indeed a very astonishing piece of news. Could it be that the Bloodthirsty Sword was capable of refining not just a person's essence blood but other kinds of energy as well?

This thought had barely emerged before Lin Yun was suddenly shaken.

Indeed, the Bloodthirsty Sword… he had always been misled by both the name of the Bloodthirsty Sword and the appearance of it absorbing the essence blood of enemies. He had long noticed that what the Bloodthirsty Sword absorbed from enemies wasn't merely essence blood.

But also… innate talents… and even, realms!

Only an extremely heaven-defying magical weapon could accomplish this!

Spiritual Energy… was also one of the very important energies within a cultivator's body. The fact that the Bloodthirsty Sword could absorb and quickly refine it seemed quite normal too?

"What are its demands?"

After a few seconds of silence, Lin Yun asked.

He didn't believe that this Little Blood, after such a strong reaction, would have no demands at all and simply wanted to kindly help him refine that Spiritual Energy.

"The Bloodthirsty Sword wants to absorb half of this Spiritual Energy. Of that half, it will only take in a half, and the other half will be given to me and Little Blue. However, Brother, Little Blue and I do not need to absorb this Spiritual Energy…" Little White continued, trailing off towards the end.

"Half?" A flicker of light shimmered through Lin Yun's eyes.

If Little White and Little Blue took half of that, the spirit within the Bloodthirsty Sword would only be absorbing a quarter…

However, he wasn't confident about the spirit within the Bloodthirsty Sword!

"The Bloodthirsty Sword can only absorb a third, and then, of that third, you and Little Blue should absorb as much as you can with all your strength, no matter the amount…" Lin Yun communicated to the spirit within the Bloodthirsty Sword.

If he didn't agree to the terms of the spirit within the Bloodthirsty Sword, he would no longer feel safe using the Bloodthirsty Sword, and if so, his greatly diminished strength might prevent him from passing the fiftieth floor.

If possible, Lin Yun still very much wanted to see what lay above the fiftieth floor of the Heavenly Principle Tower.

Therefore, upon hearing the demands of the spirit within the Bloodthirsty Sword, he couldn't help but feel a bit of willingness to compromise.

Moreover, if the Bloodthirsty Sword could indeed help him absorb and refine that Spiritual Energy, his Mental Strength level would increase even faster, and most importantly, it would save him a great deal of time.

He would also have more time to challenge the higher levels of the Heavenly Principle Tower.

It was a very advantageous prospect.

Moreover, if the fiftieth floor of the Heavenly Principle Tower had treasures like the grey Crystal, who knew what other rare treasures might exist on higher floors?

And how much more powerful could the treasures from higher floors' spatial realms possibly be?

If he were to find even more impressive treasures in the higher spatial realms, the deal would become even more worthwhile.

After all, this risk was very much worth taking.

"Buzz—Buzz—"

The Bloodthirsty Sword vibrated once more, emanating a dissatisfied aura from its blade.

"The condition is simple, if you comply, we'll continue on this path; if you don't, it's fine too. I don't necessarily have to make my way through the Heavenly Principle Tower, and I don't plan to use the Bloodthirsty Sword anymore," Lin Yun said with a cold glance at the Bloodthirsty Sword.

*Hum! Hum! Hum!*

Upon hearing Lin Yun's words, the Bloodthirsty Sword vibrated even more intensely, emitting a sense of dissatisfaction and anger. Eventually, these feelings turned into compliance.

"Brother, Little Blood has agreed," Little White conveyed the sword spirit's intention inside the Bloodthirsty Sword in a timely manner.

"Good, now, return two-thirds of the Spiritual Energy you just absorbed back to me," Lin Yun stated indifferently.

*Hum! Hum!*

Upon hearing Lin Yun's sentence, the Bloodthirsty Sword once again released an aura of discontent but ultimately had no choice but to obey Lin Yun's command. Streams of pure Spiritual Energy surged out from the Bloodthirsty Sword, flowing back into Lin Yun.

*Whoosh! Whoosh! Whoosh!*

Once this spiritual energy entered Lin Yun's mind space, his Mental Strength immediately grew at an exponentially faster rate, nearly identical to the growth rate when he first absorbed the energy blood essence from the Bloodthirsty Sword.

Within merely a few minutes, Lin Yun had completely absorbed the Spiritual Energy from the Bloodthirsty Sword.

Lin Yun's Mental Strength at the twelfth level of peak cultivation had almost grown by half.

This was an extremely terrifying rate of cultivation.

Mental Strength is a very difficult force to cultivate. Many ordinary super-territory powerhouses have Mental Strength at the twelfth peak-level too, and even with the powerful state of the super-territory, it's incredibly difficult for them to increase their peak twelfth-level Mental Strength by a significant amount.

The way Lin Yun managed, in just a few minutes, to enhance his peak twelfth-level Mental Strength by a large margin was nothing short of miraculous.

"Very good!"

Lin Yun opened his eyes, and a faint smile gleamed within the depths of his black pupils.

The stronger he grew with each battle, and all so immediate, he was very satisfied with the capability of the Bloodthirsty Sword.

It had to be said, the Bloodthirsty Sword... was indeed an incredibly heaven-defying, enticing magical weapon, truly difficult for one to part with!

"Little White, Little Blue, keep an eye on Little Blood inside the Bloodthirsty Sword, and don't let him play any tricks. Otherwise, I won't hesitate to destroy it. Moreover, when those Spiritual Energies enter the Bloodthirsty Sword, make sure to absorb them fully, don't hold back.

I don't want Little Blood to grow too quickly to where you can no longer suppress him..." Lin Yun looked at the Bloodthirsty Sword and transmitted his voice to the inside once again.

"Yes, brother Lin Yun!"

"Mhm!"

The two glowing orbs within the Bloodthirsty Sword communicated quickly with pulsing lights.

"Let's go! Let's see how many Ghost Practitioners are left in this level of space," Lin Yun said softly, looking ahead.

Whoosh—

As he spoke, he stepped forward, darting swiftly towards the destination ahead.

"Hehehe, it's been a long time since I've encountered a spirit, you can stay and become my delicacy," a hoarse voice suddenly echoed through the mountains, cackling, after Lin Yun had been walking for dozens of minutes.

Whoosh—

The next instant, a gust of gloomy wind rushed towards Lin Yun.

"A second-level super-territory Ghost Practitioner?" Lin Yun's eyes narrowed slightly as he observed the enemy.
