I am asking the Ancestor to ascend to heaven in the world of "Covering the Sky".

Dark lightning ripped through the universe, and the Chaos Lotus bloomed across the entire starry sky. One after another, phantom figures of True Immortals appeared, holding the Elixir of Immortality in their hands, and were walking towards the Ji family.

Inside the divine furnace, all the substances melted and coalesced together.

These are divine liquids formed from various rare treasures of heaven and earth, emanating astonishing and terrifying fluctuations.

You know, who in this world would dare to use various extreme weapons, Primordial Life Stones, and humanoid immortality elixirs to forge weapons?

Perhaps only Ji Lingyun could do that.

During this process, extraordinary phenomena soared into the sky around the divine furnace, such as the emergence of a green lotus from chaos and the descent of celestial kings from the heavens, shaking the entire universe.

The entire Ji family seemed to have transformed into a vast celestial realm, where various mythical beasts such as true dragons, phoenixes, Kunpengs, and Qilins soared and roared, shaking the heavens and earth.

"boom!"

The entire divine furnace was filled with crimson clouds that soared into the sky, piercing through heaven and earth, resembling a celestial river, dazzling and radiant.

The Heavenly Question Divine Sword is floating inside the divine furnace, constantly devouring various divine substances in an attempt to advance to the Quasi-Immortal King realm.

Various kinds of celestial gold were continuously poured into it, each one a rare and precious treasure, making it an incredibly extravagant waste.

This process shocked the entire universe, with extraordinary phenomena appearing all day long.

Ji Lingyun used all his strength to activate the immortal fire, continuously carving quasi-immortal king-level immortal runes. It took him a whole day to finally melt all these rare treasures down.

At this moment, let alone the Heavenly Questioning Divine Sword, even the aura emanating from those divine gold liquids was extremely terrifying, enough to suppress all kinds of extreme weapons.

Because it contains so many Dao runes, and its material is incredibly amazing.

Over the countless years, who else has been able to use so many divine artifacts to forge weapons like Ji Lingyun?

Even an emperor couldn't do that; it's truly astonishing.

At this moment, he spread his five fingers wide, and various immortal runes condensed at his fingertips, like rounds of dazzling silver suns blooming, directly suppressing the light of the entire universe.

"laugh!"

Runes flashed, pierced through, and merged into the divine furnace, blending with the divine gold liquid.

"Now it's time to use it."

Ji Lingyun stared at the divine furnace in front of him and muttered to himself.

Then he took out another item, a celestial artifact, which emitted a hazy halo in his hand.

When this celestial artifact was revealed to everyone, the entire universe fell silent.

"Isn't that the Emperor's Ascension Cauldron?!"

"The Emperor actually found this thing!"

"This is terrifying."

Gasps of astonishment echoed around the world; everyone stared in disbelief at what they were seeing.

That's the Emperor's Ascension Cauldron, a weapon forged by an unparalleled genius from the mythological era, which Ji Lingyun has now found.

"Could it be that the Great Emperor intends to integrate the Ascension Cauldron into his own weapon?!"

Someone spoke up and shared their guess.

Upon hearing this, everyone turned to look at him, their eyes filled with horror.

But that was indeed the case. Ji Lingyun simply raised his hand and sent the Immortal Ascension Cauldron into the Divine Furnace to refine it and fuse it with his own Heavenly Question Divine Sword.

At that moment, everyone felt a little dizzy, their heart was racing, and they felt utterly incredulous.

"The Emperor's Ascension Cauldron was melted down just like that?"

But Ji Lingyun had no time to pay attention to their thoughts.

He was going to create a quasi-Immortal King artifact, the only quasi-Immortal King artifact in this world. Without using extremely precious materials, it would be difficult to succeed.

Therefore, Ji Lingyun put in a lot of hard work, traveling all over the universe to find all sorts of materials with frightening origins.

Sure enough, after the Immortal Ascension Cauldron was thrown into the Divine Furnace, everything changed immediately. A rich auspicious aura rose up, and immortal mist filled the air, obscuring the entire Ji family compound and making it appear ethereal.

A series of grand sacrificial chants immediately rang out, as if countless immortals were praying inside the divine furnace.

At the same time, the Heavenly Questioning Divine Sword also burst forth with light, attempting to devour the Immortal Ascension Cauldron and integrate it into its own body.

But how could the Immortal Ascension Cauldron simply surrender and allow itself to be devoured by other objects?

So it immediately burst forth with dazzling light in an attempt to resist.

But a moment later, the Heavenly Questioning Divine Sword suddenly trembled, causing the Immortal Ascension Cauldron to shake violently and its light to dim immediately.

The deity within it was long gone, making it difficult to exert its full power, and it gradually became overwhelmed and suppressed.

During this time, it did consider summoning back its deity, but it was met with a slap from Ji Lingyun that nearly shattered it.

The Immortal Ascension Cauldron wailed as it was devoured by the Heavenly Questioning Divine Sword, its light fading until it disappeared completely.

At this moment, an aura of supreme holiness and power suddenly filled the divine furnace.

Countless phantoms of gods and demons manifested around them, bowing incessantly and chanting incomprehensible scriptures, appearing both sacred and eerie.

In an instant, a beam of light shot into the sky, directly lifting the lid of the divine furnace and rushing into the universe. It was extremely dazzling, so bright that even supreme figures bled from their eyes and dared not look directly at it.

Ji Lingyun carefully nurtured the artifact, refining it with her own primordial power, and even cutting her finger to drip her own blood essence into it.

At this moment, all the rare treasures of heaven and earth were melted into the divine furnace. Each and every one of them was a peerless material, so there was no need to worry about the materials being substandard.

"Just one last step!"

Ji Lingyun spoke, her eyes flashing with an astonishing light.

He then took out another celestial artifact, the Heaven-Reaching Netherworld Treasure.

He had observed that when the Source God and Source Demon used the Source Heaven Technique, they were able to contend with him simply by borrowing the power of the Dragon Vein, which was incredible.

Now he also wants to use this unconventional method of attaining enlightenment to perfect the Heavenly Question Divine Sword.

"boom!"

With a flick of his finger, he extracted the Origin Heaven Technique from the Heavenly Nether Treasure Seed. With a single glance, he grasped the technique in no time, even perfecting it further, far surpassing his previous understanding.

The next moment, he moved.

There was a "boom".

Ji Lingyun was radiant, both holy and extraordinary. He stretched out his large hand and conjured a chessboard of heaven and earth, using stars as pieces and the Great Dao as the formation, forming a vast and unparalleled array.

Chapter 420 The Birth of the Immortal Sword

In an instant, the stars in the sky trembled, the universe roared, and the great laws and divine chains of order of the entire world began to move, all surging towards the Ji family.

This scene shocked everyone. Using heaven and earth as an array, and all things as an array, to forge their own weapons, the resulting phenomena were truly terrifying.

Every single star was shining, and its inner essence burst forth, transforming into golden dragons that flew towards the Ji family.

The entire universe was like this: countless golden dragons soared, coiled with astonishing life essence, rushing in from all corners of the universe and plunging into the divine furnace.

This moment was truly awe-inspiring. Everyone was stunned, staring at the billions of true dragons in the universe, feeling utterly incredible.

Ji Lingyun's expression was serious. He quickly began to carve out one quasi-immortal king level rune after another, which shone brightly and merged into the Heavenly Question Divine Sword, allowing it to rapidly sublimate.

"Buzz! Buzz! Buzz!"

Inside the divine furnace, a terrifying transformation was taking place, with the aura of the Heavenly Questioning Divine Sword continuously rising and growing stronger.

In the end, it was as if billions of celestial weapons were clanging and trembling, like the birth of an unparalleled demon god from the chaotic ancient era.

"boom!"

With a deafening roar, a beam of light shot into the sky, piercing the entire universe and causing everything to tremble.

The three thousand Great Daos collapsed directly, blood rained down, and the Heavenly Question Divine Sword soared into the sky, standing tall in the starry sky, illuminating the entire universe!

"laugh!"

At this moment, before Ji Lingyun, a celestial sword radiated unparalleled light, piercing through heaven and earth.

The stars throughout the universe trembled in clusters, the Milky Way dimmed, and only a celestial sword stood tall, illuminating most of the universe.

Its body trembled, and tens of thousands of stars around it were instantly shattered into nothingness. All tangible matter was heading towards destruction, turning into tiny dust particles that drifted into the universe.

"Is such terrifying power simply from the tremor of the sword?"

In the Undying Mountain, the Qilin Ancient Emperor and the others stared blankly at everything before them, looking somewhat incredulous.

They could clearly feel that terrifying power; even a slight glimpse of it would be enough to tear apart these supreme beings of humanity, without exception.

"Buzz!"

The Heavenly Question Immortal Sword trembled, causing everyone to shudder and turn pale; this weapon was truly terrifying.

"Not bad, it has completely transformed into a quasi-immortal king artifact."

Ji Lingyun smiled and took it into his hand. A sense of familiarity, as if from the same source, immediately arose, as if it were his left or right hand.

The entire immortal sword looks ancient and natural, full of grandeur, but the power contained within it is enough to destroy the entire universe, which is extremely terrifying.

"boom!"

Ji Lingyun used his immortal sword to blast directly into the cave deep within the Undying Mountain.
