The Riftwind Beast let out an earth-shattering howl of agony as its massive body, covered in silvery-gray scale armor, shimmered with sharp gleams, and began to struggle frantically.

But at this moment, Lu Changsheng paid no heed to his injuries. The Nine Treasures Ruyi Bone burst forth with unparalleled radiant splendor, engulfing it, causing its scale armor to continuously char and fall off, as both the Daluo Sword Embryo and the Brahman Demon True Body slashed out.

The Golden-winged Roc, faced with such might, could only assist with one hundred and eight thousand feathers, not daring to advance.

A moment later, the enormous body of the Riftwind Beast, from struggling madly, gradually lost strength, lost resistance, and was left on the verge of death.

Even though the body of the Fourth-tier Demon King was strong and life force tenacious, it was difficult to withstand such layers of offense.

Especially since the earlier strike from the Fourth-rank Treasure Flying Dagger delivered a fatal blow to it.

Several breaths later, the body of the Riftwind Beast stiffened and, under the onslaught of Lu Changsheng and the Golden-winged Roc, its life force ceased, crashing heavily onto the island.

The Three Treasures Incarnation nearby raised a hand, retrieving the flying dagger that had penetrated the Riftwind Beast’s skull, to be nurtured once again.

Though this flying dagger has astonishing killing power, it comes with a flaw.

Each time it’s wielded, its effectiveness greatly diminishes, requiring time to be nurtured anew.

However, from the two uses observed, it’s still worth it.

The first time, outside the Vast Sand Illusion Realm, the Nascent Soul Spirit Body of Purple Grey True Monarch nearly crumbled under this flying dagger.

And this time, the flying dagger, nurtured for years in the Mystic Wood Gourd, was even more powerful, delivering a fatal blow to the Riftwind Beast before us!

The five cultivators not far away looked pale and fatigued, filled with reverence and fear as they looked at Lu Changsheng, not daring to speak.

After all, here was a fierce person who dared to confront a Fourth Rank Transformed Demon King head-on and slay it.

Their hearts trembled with fear as they watched the recent battle.

Aside from that, the Three Treasures Incarnation and the Golden-winged Roc also left them in shock, wondering if the two were twins perhaps?

Yet no tales have been heard of such a peerless powerhouse in the Stellar Sea.

"My Dao Companion wishes to undergo tribulation, so I trouble you, fellow Daoists, to guard this place for a while,"

Lu Changsheng turned to the five people, speaking in a calm and indifferent tone.

He then gestured to the Golden-winged Roc beside him, asking it to bring Yun Wanshang and Qian Zhuyan over.

"It is our honor to witness the tribulation of the senior’s Dao Companion!"

Someone immediately cupped their hands and said.

To become Nascent Soul cultivators and survive under the hand of a Fourth Rank Demon King, they were no ordinary folks, deeply versed in the ways of survival.

"Indeed, indeed!"

"Senior has saved us with such great kindness. We would like to follow you, serving at your command!"

The others saw this, unwilling to fall behind for fear that Lu Changsheng might later kill them to silence them, so they chose to submit.

After all, following such a strong individual was better than being a dog for a demon king.

Most importantly, they knew that once the Riftwind Beast refined the Five Elements Primordial Magnetic Mountain, it would silence them for good.

Lu Changsheng ignored their words, lightly lifting his palm to reveal a bone talisman.

Like a rising sun, it radiated divine light, spewing forth a torrent of life-imbued essence energy onto him.

As the essence energy surged, Lu Changsheng’s somewhat pale cheeks began to blush visibly, quickly recovering the depletion and injuries he had just suffered.

In the battle with the Riftwind Beast earlier, he not only exchanged injuries but also caused some strain on his body through the eruption of the Nine Treasures Ruyi Bone.

Although this condition could recover in a month due to his Chaos Body and undying materials, he had to maintain his state given the current situation.

The five people were once again awestruck by Lu Changsheng’s methods.

After putting away the bone talisman, Lu Changsheng converted the Yin-Yang Creation Sutra into the Myriad Calamities Poison Spirit Tome, pointing at the five, saying: "These days, I will place a prohibition on you to prevent concern, and after I will let you go."

Having said that, his golden gaze wove around, assessing the great formation on the Split Wind Island before him, contemplating taking control of this formation as best as he could.

"Yes."

"Please rest assured, senior."

The five, currently in a weakened state, did not dare to resist, their faces a mix of bitterness or forced smiles as they spoke.

"Is this the Stellar Sea? Why are you helping this demon king refine treasures?"

This time, Lu Changsheng voiced the doubts in his heart, seeking to understand the situation through them.

"To respond to senior, this is indeed the Stellar Sea. As for helping this demon refine treasures...."

The few spoke up to explain, stating that this place belonged to the depths of the Stellar Sea, also known as the Forbidden Sea.

As for why they were helping this demon king refine treasures, it was out of helplessness.

Initially, this Riftwind Beast had infiltrated the Human Clan Immortal City, posing as a Dan Cultivator, and under the guise of exploring a Nascent Soul Cave Mansion, stated that it needed five cultivators who practiced the Five Elements Technique.

But when they went to the so-called cave mansion, they realized it was all a plot by the Riftwind Beast.

It wanted to refine a spiritual treasure known as the "Five Elements Primordial Magnetic Mountain."

However, the difficulty of refining this treasure was high, requiring five cultivators proficient in the Five Elements Technique to help for the fusion of the elements to form the Primordial Magnetic Power.

Faced with such a situation, and against a Fourth-rank Transformed Demon King, they could only resign to their fate and choose to help.

Unfortunately, after years of treasure refining, they knew this demon frequently infiltrated cultivator’s territories. This round of treasure refinement also schemed something major, and it would never let them leave alive.

So they pondered to save themselves and acted during the final stage of refining.

"Just happened to encounter you, senior, else we’d be dead at the hands of this demon." 𝒇𝙧𝙚𝓮𝙬𝙚𝓫𝒏𝓸𝓿𝓮𝒍.𝓬𝙤𝓶

"Senior, we are endlessly grateful for your immense kindness!"

As they spoke, they once again expressed gratitude to Lu Changsheng, their survival instincts showing through intensely.

This was not unusual; they had painstakingly cultivated to this level, becoming high-rank cultivators, with over a hundred years of life remaining, unwilling to die in such a manner.

Lu Changsheng didn’t expect to find himself in the Forbidden Sea that Shen Yiren had mentioned.

No wonder he encountered such an unowned Fourth-rank spirit island at the doorstep.

However, the actions of this Riftwind Beast made him click his tongue in amazement.

A Transformed Demon King that actively came to cultivator territories to learn, proficient in formations and artifact refining.

This was truly a talent, no, a demon prodigy!

Lu Changsheng estimated that if this demon hadn’t spent so much time elsewhere, it might have already broken through to the Fourth Rank Middle Stage.

Immediately afterward, he became curious to take a look at the "Five Elements Primordial Magnetic Mountain" that the Riftwind Beast was refining.

Previously, the son born to Shen Yiren possessed an Upper Class Spirit Body, the "Primordial Magnetic Body," and now hearing about this Primordial Magnetic Power naturally piqued some interest.

A moment later, Lu Changsheng arrived at the almost ruined cave on Split Wind Island, using a great hand of magical power to peel open numerous broken stones, finally beholding a small five-colored mountain.

At the last minute, due to the actions of the five cultivators, this spiritual treasure ended up as a failed refinement.

Upon a cursory look, Lu Changsheng noticed that the Riftwind Beast’s refining methods were quite crude, akin to those of a nouveau riche.

Apparently, it had obtained the method to refine this treasure along with a rare Nine Extremities Mystic Magnetic Crystal, but lacking sufficient artifact refining skills, it opted for such a rudimentary technique and then deceived five Dan Cultivators to assist.

"If it had successfully refined it, possessing such a treasure, its power would truly be extraordinary."

Though this treasure was a failed refinement, the Five Elements Primordial Magnetic Power could suppress Five Elements Techniques and metal flying sword magical treasures.

Moreover, as a Fourth-rank Transformed Demon King, its physical body was already robust. If it could suppress cultivators’ techniques and magical treasures, it would be extremely troublesome.

Especially given that the Riftwind Beast had frightening speed, with few peers at its level.

"Though it was a failed refinement, so many rare materials were present; later on, I might try recrafting it."

With the Divine Mechanism Hundred Refinement Technique, a top-tier heritage, Lu Changsheng had confidence that if he elevated his artifact refining skills to the Fourth Rank, he could refine this treasure anew.

He then raised his hand to store the Five Elements Primordial Magnetic Mountain into his storage ring.

The five in the distance watched this without daring to make a sound.

After all, the Riftwind Beast had been slain by Lu Changsheng, thus everything on the island naturally belonged to Lu Changsheng.
