Gao Xuan considered that he had ample time, and his Spiritual Power was exceptionally strong.

Perhaps it was due to the Cosmic Laws; at the same Divine Soul level, Gao Xuan's Spiritual Power in the Star River far surpassed the Divine Sense of the Cultivator World.

This disparity could even reach hundreds of times.

With such enormous Spiritual Power to forge the Profound Nether Curse, it was naturally exceedingly easy. For the Profound Nether Curse is also a basic spell, which almost has no power if merely cast.

The Profound Nether Curse is used to gather Water Elemental Source Power.

Gao Xuan engraved the Profound Nether Curse with the Water Source Essence. The basic spell can be directly duplicated with Divine Sense, and then particles are combined with the material of the Hongyi Sword itself, simultaneously engraving the spell.

As long as Gao Xuan engraved a perfect Profound Nether Curse, he could use the Water Source Essence's potent learning ability to perfectly replicate the Profound Nether Curse.

This is where the charm of geometrical multiplication is reflected.

Gao Xuan kept multiplying like this for ten hours. According to his calculations, he approximately engraved 1,280 trillion Profound Nether Curses.

In the process, Gao Xuan had to rest several times. His enormous Spiritual Power was nearly exhausted.

Of course, achieving this mainly depended on the miraculous traits of the Water Source Essence itself. Gao Xuan merely formulated the plan; the rest was automatically executed by the Water Source Essence.

Without the traits of the Water Source Essence, even if Gao Xuan's Spiritual Power were ten times stronger, he absolutely could not achieve this.

1,280 trillion Profound Nether Curses probably also surpass all the Divine Artifact restriction levels in the Cultivator World.

Of course, Gao Xuan didn't have the ability to activate all these Profound Nether Curses. When his Spiritual Power bursts fully, he can only trigger a small portion.

This small portion likely amounts to one ten-billionth.

Even after he achieves Virtual Godhood, it might still be difficult to fully activate all the Profound Nether Curses on the Hongyi Sword.

Gao Xuan also felt that doing this seemed to bear little significance. Yet, having such an opportunity to transform the Hongyi Sword into the first Divine Sword ever is also very fulfilling.

Moreover, refining the Hongyi Sword like this does not affect its use by him. As long as his Power increases, the Hongyi Sword's power will also enhance.

Through this ritual enchantment, Gao Xuan also integrated his Sword Intent into the Profound Nether Curse.

The Hongyi Sword cannot be called the invincible Divine Sword, but it is unique enough. Its Power ceiling is also exceptionally high, and it resonates extraordinarily well with Gao Xuan.

Throughout endless Multiverses, it's impossible for anyone to resonate with the Hongyi Sword better than he does.

Compared to the patched-together Infinite Godslaying Spear, Gao Xuan actually prefers the Hongyi Sword. Yet, its power still doesn't surpass the Infinite Godslaying Spear.

This is not surprising. Even with numerous layers of Profound Nether Curse stacked, it's futile without activation.

Furthermore, the Infinite Godslaying Spear inherently possesses extremely strong Divine Artifact traits. Currently, the Hongyi Sword is still lacking a level compared to the Infinite Godslaying Spear.

Fundamentally transformed, it's not quite appropriate to still call it the Hongyi Sword.

"From now on, you'll be called the Yi Ming Sword..."

Gao Xuan murmured to himself, and the blade resembling autumn water slightly trembled, with tidal elements flowing on the blade, seemingly protesting this unpleasant name.

Gao Xuan laughed heartily: "I knew you weren't dead!"

Inside the Hongyi Sword, there was a buzzing vibration, and the sword light resembling water waves surged like an angry tide.

Within the layers of swirling water waves, the appearance of the Water Source Essence could faintly be seen.

Through the ritual enchantment of the Profound Nether Curse, the Water Source Essence unexpectedly reincarnated attached to the sword.

Gao Xuan gently brushed the clear and bright blade, his hand pitch-black as if resembling a ghost claw.

With just this subtle brush, the shadow of the Water Source Essence hidden within the Hongyi Sword was forcibly grasped out by him.

The wisp of water-hued smoke formed by the Spiritual aspect of the Water Source Essence twisted and struggled within Gao Xuan's black palm, yet it couldn't escape from his grasp.

Gao Xuan laughed again: "Treasured one, let me teach you something obediently. This is the God-slaying Vortex. It's not shared in the information given to you. Specifically designed to destroy Divine Soul Spirits, treasured one, savor this taste carefully."

The Water Source Essence twisted violently, but in the end, within the black palm, it gradually transformed into a wisp of black smoke dispersing in all directions. Thus, all Spiritual aspects dissipated, and the connection with Gao Xuan's Soul Chain was completely severed.

Gao Xuan said with some sentiment: "This world is too ruthless, not suited for naive little treasures like you..."
