However, later on, a divine phoenix underwent nirvana here. Its divine fire spread across the entire Phoenix-Roost Mountain, burning for thousands of years without extinguishing.

Adam and Maren arrived at the foot of Phoenix-Roost Mountain. The summer heat was sweltering, and a wave of scorching air rushed at their faces.

The two circulated their profound methods, locking the life force around their bodies, and made their way up toward the peak.

Although Phoenix-Roost Mountain was blisteringly hot year-round, it was the absolute favorite environment for Blazing Sun Grass, which grew especially vigorously within the crevices of the cliff walls.

Blazing Sun Grass was entirely crimson red and no more than a foot long. It was the primary spiritual ingredient for refining the Spirit Nurturing Pill.

On the way up, Maren mentioned that her ancestor Raiden had been picking Blazing Sun Grass here when he lost his footing and fell off the cliff.

Yet, receiving a blessing in disguise, he accidentally stumbled into that secret realm.

Arriving at the summit, a bottomless abyss lay beneath their feet, mist flowed and a sea of clouds churned.

The cliff wall was smooth and sharp, as if neatly sliced off by some massive heavy weapon.

Standing at the peak, Adam executed his innate divine ability, Omniscience of All Things, and looked toward the churning sea of clouds.

Sure enough, from beneath the thick clouds, a powerful wave of energy transmitted upward.

Beside him, Maren summoned the ancient jade and silently chanted an ancient incantation. The churning clouds gradually dispersed, and a spatial door slowly emerged in mid-air.

"Young Master Adam, this must definitely be the secret realm where my ancestor Raiden obtained his fortuitous encounter a thousand years ago!"

Maren’s face lit up with joy, grabbing Adam, she leaped into the spatial door. Following that, the spatial door closed shut behind them.

Within the Medicine Immortal Secret Realm, from the moment they stepped foot inside, Maren’s gasps of amazement rang out continuously, never once ceasing.

"This is the Nine-Leaf Soul-Returning Grass! The alchemy manuals record that this grass went extinct eight thousand years ago!"

"Could this be the Qilin Holy Spirit Fruit that has been extinct since the Old Era?! And it’s actually ten thousand years old! Hahahaha, this secret realm truly is a blessed land of immortals!"

"Ah!!! Could... could this be the legendary Three-Leaf Undying Flower?! Rumor has it that a single leaf can grow flesh on bare bones and possess the miraculous effect of bringing the dead back to life!"

"Wow..."

Maren’s exclamations echoed continuously in Adam’s ears. However, Adam remained entirely unmoved and did not take it to heart.

These spiritual ingredients might be incredibly precious to Maren, but for Adam, already an Entering the Dao existence, their appeal was not nearly as great.

He was now an Entering the Dao existence, merely three steps away from becoming a Heaven and Earth Deity.

With the Misty Ghost Forest serving as a perfect natural cultivation ground, he was confident he would step into the Heaven and Earth Deity realm very soon.

The spiritual ingredients Maren kept exclaiming over were nothing but rare yet ordinary items when looking at the Medicine Immortal Secret Realm as a whole. Months ago, when he comprehended the Pill King’s Precious Mirror, he had caught a glimpse of a corner of this secret realm.

Only in the deepest depths of the Medicine Immortal Secret Realm did the true heaven and earth treasures and peerless immortal flowers reside.

If he could obtain those treasures, let alone as a Mortal Supreme, even after stepping into the Heaven and Earth Deity realm, they would still provide massive help in elevating his strength.

This Medicine Immortal Secret Realm is so precious and contains such extraordinary treasures.

Why has it appeared so early in the Heaven and Earth Upheaval? And to think it actually appeared in a barren, impoverished place like Silver Willow!

Adam stood atop a bluestone slab, a trace of doubt flashing in his eyes.

Whenever a Heaven and Earth Upheaval began, secret realms, rare treasures, and heavy artifacts would reappear in the world.

Over the course of the previous five upheavals, perceptive individuals had deduced certain patterns.

The more barren a region, the smaller the chance of rare treasures appearing, and the closer an Upheaval evolved toward its peak, the greater the chance of heavy artifacts appearing.

No one knew the exact reason, but countless ancient texts consistently proved this point.

Ever since recorded history of the Upheavals began, Central Continent had always been the grandest battlefield where major cultivators fought for opportunities, simply because peerless treasures that triggered massive changes in the Mysterious Yellow Great World had appeared there multiple times.

Ancient records stated that when the Third Heaven and Earth Upheaval evolved to its absolute peak, the Dao Palace of an Ancient Emperor appeared in Central Continent

In an instant, the entire continent became an ancient battlefield.

To snatch the opportunities within the Ancient Emperor’s Dao Palace, cultivators from across the Mysterious Yellow Great World converged and fought a world-shattering war.

Central Continent was nearly shattered to pieces, and countless living beings perished.

In Adam’s view, even if the peerless immortal herbs in this Medicine Immortal Secret Realm were not quite as precious as an Ancient Emperor’s Dao Palace, they were not far off.

Logically speaking, a secret realm of this caliber should only appear in Central Continent when the Upheaval evolved to its absolute peak.

At the very least, it should have appeared in one of the other major continents.

Although the momentum of this current Upheaval was exceptionally grand, far surpassing previous ones, and it was not impossible for such a secret realm to appear early on, it absolutely should not have appeared in the barren lands of Silver Willow. 𝗳𝚛𝗲𝕖𝕨𝕖𝗯𝚗𝚘𝕧𝕖𝗹.𝗰𝗼𝕞

Could it be that this Heaven and Earth Upheaval has deviated from the norm, and Silver Willow will gradually become the center of this Upheaval?

Unable to figure it out, he knew this was merely a conjecture.

With his current strength, he still could not pry into the operational mysteries of the Mysterious Yellow Great World, not even with the innate divine ability Omniscience of All Things.

Unless he could cultivate Omniscience of All Things to the perfection stage, but achieving that in a short time was far too difficult for Adam.
