Chapter 504: Dao Accomplished! The 123rd Meridian!

In the Hall of Longevity, the slayer of that former Jue Dian Immortal King stared at the purple‑black sea of thunder above the Heavenly Dome, slightly startled.

He never imagined that a heavenly tribulation could be this terrifying.

The strength of this tribulation is such that even an ordinary Immortal King might not be able to withstand it!

And Gu Yuan now… isn't even a True Immortal.

How is this a test?

This is clearly an execution that leaves no chance of survival!

The Myriad Medicines Divine Lord's expression also turned extremely grave.

He muttered to himself: "The Young Master… what on earth is he trying to do? With the cultivation of a Heavenly Emperor Realm, to head‑on resist this level of world‑annihilating tribulation…"

Only Gu Gong, after a brief shock, showed a hint of fervor in his eyes.

"Prove the Dao with my body, temper the body with the tribulation!"

"The new lord… he is emulating the most heaven‑defying gods and demons of ancient times, intending to turn this world‑annihilating heavenly tribulation into the supreme ladder for his ascension!"

Amidst the starry sky, Gu Yuan faced the heaven‑destroying, earth‑annihilating sea of thunder, his expression still calm.

He could feel that the will of the Heavenly Dao of the Primeval Immortal Realm had already locked onto him completely.

That icy, merciless killing intent had almost solidified into substance.

This is not entirely a provocation aimed at Gu Yuan.

There has also been, all along, the Gu Family's way of 'evading' the heavenly tribulation that a True Immortal ought to face.

The Heavenly Dao's dissatisfaction with the Gu Family has been continually accumulating.

It's only that, forced by the ever‑stronger Gu Cangsheng, they have had to endure it.

Now, at last, they have a perfectly natural opportunity for revenge.

Even the Heavenly Dao wants to give this ignorant junior a proper lesson!

Come on.

Gu Yuan opened his arms, as if embracing his destiny.

Boom—crack!

The first tribulation lightning finally fell.

It was a purple‑black thunder pillar so thick it defied description, tearing apart the darkness of the universe; wherever it passed, space shattered inch by inch, revealing the heart‑shaking chaos and void beyond.

The power of this strike already far exceeded that of an ordinary True Immortal.

Yet Gu Yuan neither dodged nor evaded.

He didn't even use any technique, merely meeting it head‑on with his flawless fleshly body.

Bang!

The thunder pillar slammed solidly into his chest.

The terrifying energy capable of instantly reducing a life‑bearing ancient star to dust raged wildly across his body's surface.

But Gu Yuan's body merely trembled slightly.

On his jade‑like, crystalline skin, not a trace of scorching remained.

Instead, the violent thunderous force seemed to find an outlet, rushing frenziedly through his pores into his interior, where it was absorbed and turned into nourishment for tempering his flesh and soul.

"It's too weak."

Gu Yuan shook his head, seeming somewhat dissatisfied.

His words seemed to utterly enrage the Heavenly Dao.

Boom—rumble!

The thunder sea surged—second bolt, third bolt, tenth bolt…

Hundreds upon thousands of tribulation bolts, far more terrifying than before, poured down like a violent storm, covering the sky and earth.

This time, the lightning was no longer mere energy attacks.

They took on various forms.

There were ancient thunder gods wielding lightning spears and clad in electric armor; there were thunder‑marsh dragons tens of thousands of feet long, spewing annihilation god‑lightning; and even a thunder‑kingdom forged from pure lightning law descended to suppress him from above.

Each attack was enough to heavily wound a True Immortal.

Combined,

even an Immortal King would have to retreat.

"This is getting interesting."

In Gu Yuan's eyes, a spark of fighting spirit finally ignited.

He no longer passively endured the blows; instead, he actively charged into the sea of thunder.

"Fist Opens Heaven and Earth!"

He threw a punch, using no grand dao laws, just pure physical strength.

But the power of that punch directly shook the origin of the universe.

That invincible ancient thunder god, together with the lightning spear in his hand, was shattered to pieces by that single fist.

"Footsteps on Mountains and Rivers!"

He stepped down, and the thunder‑kingdom that had come to suppress him let out a groan it could not bear, collapsing on the spot.

Gu Yuan's figure moved freely through the endless thunder sea, as if entering an uninhabited realm.

He regarded this world‑annihilating tribulation as a trial to test his new Dao body.

He employed the most orthodox cultivation method of the Primeval Immortal Realm to openly and rightly endure the strongest tribulation sent down by the Heavenly Dao of the Primeval Immortal Realm.

Time flowed slowly in this tribulation that could be called mythic.

The attacks within the thunder sea grew ever more terrifying and ever more strange.

In the end, even war generals of the immortal court bearing the supreme Immortal King's decree evolved, and even war‑general phantoms whose bodies might compare to the Jue Dian Immortal King appeared!

But no matter how the Heaven Tribulation changed, Gu Yuan always remained at ease.

He seemed to become an immortal war god born for battle, growing stronger when meeting strength, wildly dancing on the edge of life and death, blasting those opponents forged from tribulation lightning one by one.

Finally.

When, in the Thunder Sea, no new attack forms could be evolved any longer.

All the lightning began to contract and coalesce toward the center.

In the end, it formed a strand only thumb‑wide, its whole body appearing as a chaotic black thunder that seemed able to swallow all light…

This tribulation thunder contained no law, no will.

What it represented was only the purest, returning‑to‑origin… nothing.

It is the ultimate of destruction, and also the beginning of all things.

Seeing this black thunder, even Gu Cangsheng, who had always appeared calm and carefree, for the first time wore a solemn expression.

"Return‑to‑origin Divine Thunder…"

He recognized this ultimate thunder punishment that exists only in the oldest legends and that even the Jue Dian Immortal King feared.

The black thunder was silent and soundless; it did not tear space, nor did it trigger any anomalies.

It simply drifted quietly toward Gu Yuan's brow.

As if it had crossed the distance of time and space.

Gu Yuan's pupils suddenly contracted.

For the first time, he smelled a hint of true death in this Heaven Tribulation.

He knew this strike could neither be evaded nor blocked.

Unless he employed myriad time lanterns.

But this time,

Gu Yuan did not wish to use his grandfather's power.

He had his own method.

At the instant the black thunder was about to touch his brow, Gu Yuan sank his heart‑spirit completely into that dormant life‑bound Dao fruit.

Hum—

The black thunder merged into his brow.

There was no earth‑shaking explosion, no world‑destroying energy storm.

Gu Yuan's body simply floated silently in the starry heavens, as if frozen into an eternal sculpture.

All the life force within him dissipated at that moment.

Vitality returned to nothing.

Dead?

Within the Hall of Eternal Life, the Divine Lord of Ten Thousand Medicines and Tu's heart instantly sank to the abyss.

Even Gu Lin Tian could not help clenching his fists, his eyes showing tension.

Only Gu Cangsheng stared at his grandson, his chaotic eyes flashing with a sharp light.

"No… it's not over yet!"

Just as everyone thought Gu Yuan had already perished and his Dao vanished,

a faint, almost undetectable seven‑colored afterglow quietly ignited within his lifeless body.

That was the source of the World Tree.

It is the beginning of life, the source of all things.

Immediately after, a greenish light lit up, the Dao resonance of the Immortal Body of Eternal Life.

A brilliant dawn light flared, the foundation of the Divine Dawn Dao vein.
