I have Immortality In The Cultivation World

Zhou Yi currently possesses the Black Tortoise Armor for defense, the Bodhi Treasure Wheel for assistance, and the Light Dividing Sword for offensive capabilities.

The power of the Mountain and River Cauldron and the Soul-Calming Mirror has been increasing day by day as they are nurtured with mana. Although their number does not surpass that of True Lord Wan Bao, their quality far exceeds his treasures.

"What kind of treasure is suitable to refine with the Dragon Emperor Treasure Bead?"

After a moment of thought, Zhou Yi made up his mind. Since the bead was indestructible, it was best to refine it into a treasure for personal protection.

With eternal life already attained, all that was needed was to focus on stacking armor and magic resistance!

Having comprehended the Earthly Fiend Restriction for more than five hundred years and practiced engraving on ordinary spiritual objects, he had mastered the technique. Engravings, such as the Bamboo Sword of Qin Zheng, could be completed with a wave of his hand.

This method did not require auxiliary items, and in this era of scarce spiritual materials, it was far more useful than formulas of magic artifacts.

Spiritual light sparkled at Zhou Yi's fingertips as it landed on the surface of the bead, beginning to engrave the first Earthly Fiend Restriction.

Solidness!

After more than half an hour, a large amount of mana had been consumed, but the surface of the spiritual pearl remained as smooth and shiny as ever.

"Is it really that hard?"

Zhou Yi's brows furrowed slightly, and a bad feeling arose in his heart. He then spat out the Mountain River Precious Cauldron.

The cauldron contained the nurturing sword, wheel, and mirror, emitting sparkling baoguang radiance that reflected each other.

The Light Dividing Sword had been severely damaged, but its essence remained intact; it could be restored with prolonged nurturing. However, the Bodhi Treasure Wheel was unexpectedly troublesome. The spirit within was affected by the malice of the Blood Sacrifice and had turned into a wicked demon, devouring the Qi-Blood and souls of living beings upon activation.

Now with no other options, Zhou Yi could only slowly purify it with mana until the malicious spirits were completely eradicated.

Fortunately, the spirit of an artifact differed from the divine soul of a cultivator; it would not be damaged after being purified but, instead, would be easier to refine and recognize a new master.

Zhou Yi, holding the Light Dividing Sword, attempted to engrave the Earthly Fiend Restriction on the bead, but the result was the same as before. He then tried dozens of different spells and magic artifacts, yet none could leave the slightest mark.

"Could this thing only serve as a hard glass ball?"

"This object, having consumed the accumulated essence of Greenwave Pond over ten thousand years and the sacrificed essence, Qi, and souls of countless demon tribes, is rare in this world and too extravagant to be used merely as a plaything!"

"After the dissipation of the restriction within the Blood Crystal, the old dragon regained its senses and wandered within the bead for a long time..."

At this point in his thoughts, Zhou Yi thoroughly explored the inside of the bead, which proved to be solid and stable, perfectly unified like the primeval chaos. Pondering for a moment, he used the Soul Division Secret Technique to peel off a wisp of his Divine Sense, condensing it into an ethereal silhouette.

Zhou Yi practiced the cultivation technique for nurturing the soul during the Qi Refinement Realm, the Nine Revolutions for refining the soul in the Foundation Establishment Stage, and had now shifted to studying the Buddhist Nirvana Sutra.

The cultivation of the soul and body was not limited by the Spirit Root and grew slowly but steadily, and Zhou Yi's soul had become substantial.

This Soul Division Secret Technique was an inheritance of the Ghost King Sect. Upon mastery, one could divide their soul and reside within another's body, subtly influencing the cultivator's thoughts and actions. According to records, the technique was derived by predecessors who referenced inner demons.

Under Zhou Yi's control, the divided soul used an Escape Technique and lunged at the bead.

It passed through as if moving through a curtain of water or crossing a barrier, and the divided soul entered a wide expanse of white space in all directions.

The divided soul's Divine Sense swept across the area, which was three hundred feet in size and spherical in shape. Zhou Yi guided his divided soul to wander within this space, and when it touched the crystal-clear edges, he tried to engrave the Earthly Fiend Restriction.

On the outside, the bead was indestructible, but inside it was as soft as water, so even the weakened divided soul could leave marks.

"Interesting! This truly is a fine treasure!"

Zhou Yi repeatedly expressed his admiration, realizing the vast potential uses of the space inside the bead.

The first thing that came to mind was to refine it into a protective treasure that could be used as a refuge during a deadly calamity from the heavens, able to withstand even the attacks of a Divine Transformation Heavenly Monarch.

The second idea was to refine it into a Cave Heaven treasure, in which to place his seclusion space, making relocation much more convenient.

As time passed, with the continuous expansion of the Cave Heaven, reaching miles in all directions, it could be used to establish a sect or even create an entire world.

Zhou Yi let his mind wander, dreaming of becoming the master of a world, when the divided soul within the bead slowly twisted and dissipated, vanishing into nothing shortly after.

"Can the bead not support living things, or is there some other reason?"

"It seems I was thinking too simply. If creating a Cave Heaven were this easy, then the Sacrificial Method should be renamed the Sky-Opening Method! Still, there are ways to resolve this, like the difference between the Beast Controlling Bag and the storage bag—the former retains an opening connected to the outside world."

"Perhaps piercing through the bead's barrier and uniting it with the outside world could make it possible to support living things?"

Zhou Yi acted upon his decision and once again used the Soul Division Secret Technique. His divided soul carried the Light Dividing Sword and deployed an Escape Technique, only to be blocked outside the Treasure Bead.

"It seems that only the soul can enter!"

The divided soul escaped into the Treasure Bead, flew to the spot where he had just engraved the restriction, transformed into the shape of an electric drill, and began to rotate and bore a hole.

Zhou Yi estimated the time—before his divided soul collapsed and dissipated, he used an Escape Technique to fly out of the Treasure Bead's space and reintegrated with his divine soul, immediately noticing a slight sense of fatigue.

"The speed of penetrating the barrier is somewhat slow, but what I have the most is time!"

Zhou Yi didn't care if the Treasure Bead would lose its indestructible properties after being damaged. If it couldn't truly be refined into a magic artifact, it would be nothing but a glass bead.

...

The mountain originally had no name, from now on it shall be known as Kunlun.

From there, Zhou Yi resumed his daily cultivation practice, adding Soul Power to his usual consumption of mana and lifespan.

"Thinking it over, how do I not resemble a health potion and mana potion?"

Apart from cultivating, he recited and studied Buddhist and Taoist scriptures, comprehending the teachings of the sages. The heritage books plundered from the Buddhist sect had been completely arranged and recorded in the Taoist canon during his sixteen years in the Western Sea.

"In the last five hundred years of the Dharma, even though the high monks strive to preserve it, it's been continuously lost and reduced through generations. Many Buddhist secret techniques are already incomplete, fortunately, a few sect-defending cultivation techniques remain intact."

One of them is the Nirvana Sutra!

The Buddhist sect focuses on the path of the soul, and unlike the Ghost King Sect which specializes in ghost cultivation and soul division, Buddhism is particularly adept at refining the soul, with the ultimate goal being to transform the illusory into the real and concoct Shariputra.

The Nirvana Sutra is the Buddhist sect's supreme technique for soul concentration, which not only far exceeds the soul refinement lineage of the Dan Ding Sect but also has two marvelous uses when fully cultivated.

Annihilation and Nirvana.

Once the Annihilation Secret Technique is deployed, the divine soul becomes withered and lifeless, making it undetectable even to the face of a Nascent Soul ancestor.

The Nirvana Secret Technique, on the other hand, deals with the path of reincarnation and can explore the rebodied souls through the relics of the deceased.

"Could there really be reincarnation in this world? All Buddhist scriptures mention it, perhaps it's not without basis! The matter of reincarnation is significant; there's no need to rush into exploring it. Once I've fully cultivated the Nirvana Sutra, I'll try to seek out my old acquaintances to see the truth."

Inside, Zhou Yi refined the Stellar Secret Record, and externally, he cultivated the Ancient Purple Sun Scripture, while also possessing the Buddhist sect's secret transmission for the soul.

"Having reached the pinnacle of spirit, Qi, and essence in the teachings of both Buddhism and Taoism, and having obtained the sect's supreme treasure, this end of the Dharma truly is a great opportunity for me!"

Time flies.

The sun and the moon replaced each other, and the seasons revolved.

Years passed in the blink of an eye during secluded cultivation, and a hundred years had already flown by.

On this day.

Celestial phenomena appeared near Serpentine Mountain, with stars manifesting in the daylit sky as countless beams of starlight descended.

Inside the Taoist temple of Kunlun Mountain.

The power of the stars continuously tempered Zhou Yi's body; his inner organs, meridians, and muscles shone with specks of starlight, eventually forming a diamond-shaped mark on his forehead.

After five hundred years of cultivation, he finally refined the Stellar Body.

"The power of my spells has greatly increased. I can condense a vestment robe of starlight to protect myself during battles and draw upon the power of the stars to restore mana... Unfortunately, who else in this world can contend with me in a spell duel?"

Zhou Yi's eyes were clear and cold, without sadness or joy.

Over the century, he immersed himself in reading and comprehending Buddhist scriptures, his mind becoming increasingly still and waveless, to the point where he hadn't even gone out to celebrate once.

Such a state of mind was precisely suitable for the cultivation of the Nirvana Sutra. The growth of his divine soul had increased by more than fifty percent, which correspondingly greatly accelerated the speed at which he was penetrating the barrier of the Treasure Bead.

"In another hundred and eighty years, I will be able to refine a mobile cave abode, no longer confined to the desolate wilderness!"

"I wonder if the house in the capital still exists. When the time comes, I can move back in..."
