Let you simulate life, but you change fate every time?!

Their bodies, along with the entire Cyan Grass Mountain, were engulfed by a blast of energy, instantly turning to dust and disappearing into nothingness.

This was the terrifying power of the Enlightenment Immortal Venerable.

With just one strike, eternity becomes void!

And that's not all.

When the Longevity Immortal Venerable's palm struck Lu Yuan, a significant amount of dark mist surged into his body, attempting to erode and assimilate him into a Dark Creature!

If it had been pure Dark Origin power, Lu Yuan would definitely have fled as far away as possible without looking back.

However, this dark mist was merely a means exhibited by the corrupted and degenerated Heavenly Dao Will, imitating Dark Energy.

Perhaps it was more than enough to deal with a Harmonization Celestial Monarch, but it posed no threat to Lu Yuan.

"Buzz!"

Inside Lu Yuan's dantian.

The Supreme Immortal Embryo Gu held a Dharma Seal in its hand as countless Law Runes appeared.

Each rune represented a kind of Law Origin.

And at this moment, the number of these runes was so vast, like a brilliant array of stars, numbering at least in the tens of thousands!

As soon as these runes appeared, they encircled Lu Yuan like stars surrounding the moon.

This caused his momentum to soar, as his eyes emitted a captivating divine light between blinks.

Like an Ancient Divine King dominating all beings, his aura had reached the zenith of terror.

The dark mist, which could devour everything and made the Harmonization Celestial Monarch despair, evaporated when illuminated by divine light, disappearing into nothing immediately.

"Kill!"

Lu Yuan advanced aggressively, once more engaging in a life-and-death duel with the Longevity Immortal Venerable.

This battle.

Either you perish, or I am destroyed.

There's no retreat possible!

However, the Immortal Venerable is hard to extinguish.

What's more, the Longevity Immortal Venerable, as the foremost Gu Dao authority, was hardly harmed by any Immortal Gu.

Additionally, after being modified by Dark Energy, his flesh body had nearly achieved eternal immortality.

Even if Lu Yuan used an Absolute Killing Technique to turn him into a bloody rain scattered across the sky, the Longevity Immortal Venerable could instantly restore himself!

"The will of heaven cannot be defied, outsider, you are courting death!"

The Longevity Immortal Venerable snorted coldly, his icy eyes filled with intense killing intent.

He extended a hand.

In an instant, stars shifted, the universe seemed to overturn.

Before Lu Yuan could react, a palm struck his chest, sending his body flying backward, blood splattering, dyeing the sky red.

But immediately after.

He took a deep breath, and his collapsed, broken chest bone restored to its original state.

His aura also returned to its peak state, showing no sign of any injury!

Because an Immortal Venerable expert is indeed too difficult to kill.

Even if the Great Dao becomes void and the heavens are destroyed, the Enlightenment Immortal Venerable can transcend beyond the world, unaffected by anything.

And for an Immortal Venerable expert to kill a being of the same level is as hard as achieving Enlightenment Dao again!

This battle was indeed brilliant and splendid to the extreme.

Lu Yuan and the Longevity Immortal Venerable both unleashed Absolute Killing Techniques, even going as far as to reverse the River of Time, trying to go back to the past and smother each other in the cradle before they had grown.

"Splash~"

The River of Time was affected by the battle, becoming turbulent and very unstable.

A drop of river water splashed into the air, dreamlike, within it countless scenes emerged.

The scene showed a nursing infant lying in swaddling clothes, striving to refine the Innate Qi within its body.

The next second.

A flash of light, and the figure of the Longevity Immortal Venerable suddenly appeared in front of the infant.

Just as he raised his palm, before he could even kill the baby, Lu Yuan's Dharma Body rushed out of the River of Time, launching into another life-and-death struggle with him.

In another drop of river water.

Within a secluded ancient village.

A seemingly ordinary young boy was sitting cross-legged, trying to refine his first Gu Insect.

But the next moment.

Lu Yuan broke into the ancient village, attempting to kill the not-yet-grown Longevity Immortal Venerable.

However, before he could take action, the River of Time surged, and the Longevity Immortal Venerable's figure materialized, intercepting Lu Yuan directly.

Such scenes continued to play out.

Lu Yuan and the Longevity Immortal Venerable reversed the River of Time, their myriad Dharma Bodies fought and slaughtered across different time nodes.

From the flourishing Ancient Times of Gu Dao to the parasitic cultivation era dominated by the Insect Race.

In the end.

Lu Yuan and the Longevity Immortal Venerable fought through the River of Time, leaving only their figures in the entire universe.

They battled until space-time was chaotic and the heavens and earth shattered, yet they could not completely erase each other's presence!

After all, an Immortal Venerable, once proven, is forever proven.

Existing simultaneously in the past, present, and future.

If one wishes to kill an Immortal Venerable, the only way is to erase all traces of his existence from the River of Time.

But this method is as difficult as ascending to the heavens, and almost no one can achieve it.

However, as time passed,

The Longevity Immortal Venerable was shocked to discover that Lu Yuan's power was slowly growing!

Although compared to the boundless and immense power of an Enlightenment Dao Immortal Venerable, Lu Yuan's growth was slow, almost negligible.

But no matter what,

Lu Yuan's power was gradually increasing, unstoppable!

[Your Heaven-defying Comprehension engages in a life-and-death battle with the Longevity Immortal Venerable, slightly breaking through your Daoist Skill!]

[Your Heaven-defying Comprehension reverses the River of Time, battling simultaneously in past, present, and future, deepening your understanding of Space-Time Origin!]

[Your Heaven-defying Comprehension successfully comprehends a trace of the Longevity Immortal Venerable's Dao and Skill, knowing yourself and your enemy, a hundred battles a hundred wins, you gradually gain the upper hand in battle!]

For Lu Yuan, who possesses Heaven-defying Comprehension.

Battle is the fastest way to become stronger.

And as the prompts sounded,

Lu Yuan's growth rate became increasingly faster, from being on par with the Longevity Immortal Venerable to gaining the upper hand.

Finally, the entire battle situation became one-sided, with Lu Yuan suppressing the Longevity Immortal Venerable!

This battle lasted for over a millennium.

The heavens and earth sank, and order collapsed.

Lu Yuan, dragging his scarred and exhausted body, executed the final Absolute Killing Technique.

"Boom!"

The River of Time raged out of control, countless waters evaporating into thin air.

And the silhouette of the Longevity Immortal Venerable became dim and illusory, finally shattering like foam, disappearing forever from the past, present, and future.

Seeing this scene, Lu Yuan's already numb body and nerves could finally relax for a moment.

Such an intense battle is an unbearable torment even for an Immortal Venerable.

If not for Lu Yuan's numerous reincarnations honing his indomitable will,

He might not have lasted until the Longevity Immortal Venerable's life and death Dao dissipated; he would have collapsed first.

It was through this battle,

Lu Yuan finally understood what the four words "Immortal Venerable Difficult to Extinguish" truly meant.

He exhaled a long breath of turbid air, his exhausted body wobbling, almost collapsing to the ground.

After standing there resting for a long while, he barely regained a bit of strength.

But when Lu Yuan turned back to look in the direction of the Spirit Realm again,

He found that the heavens and earth were shattered into pieces, leaving only a void.

All life perished, eternity hollowed.

Such is the price of killing an Immortal Venerable.

Even if one wins this battle, so what?

When the victor suddenly looks back,

He discovers that friends, family, and everything familiar is no longer there.

In the vast world and boundless starry sky, he is ultimately left alone.

In a way,

It's almost no different from mutual destruction!

"Enough, born here, grown here, die here."

"This realm perished because of me, so I shall return life to the heavens and recreate reincarnation."

Lu Yuan stood tall in the endless starry sky, sighing deeply.

He opened his right palm, where lay a Gu Insect with barely a breath left.

Then Lu Yuan clenched his fist again.

Pouring his lifetime of Dao and Skill, and all Life Energy, into this Gu Insect.

At that moment,

Light burst forth, impossible to behold.

Thus, the Destiny Immortal Gu was refined!

Unlike the Longevity Immortal Venerable's yet-to-be-completed Destiny Immortal Gu.

The Destiny Immortal Gu before Lu Yuan was in peak status, radiating the power of reincarnation and time.

With a gentle tremor, the River of Time instantly reversed.

The Spirit Realm, once broken and barren, resurrected from extinction, blossoming a strand of vitality.

And across the Spirit Realm, all creatures were revived, restored to their original state.

However, as the price,

Lu Yuan's figure became transparent and illusory, finally completely vanishing into the heavens and earth.
