That night.
Ye Chen silently entered the Luo River Mountain Range, easily traversing millions of li, passed through the Million Mountains, and entered the deepest part of the mountain range, where he beheld the Luo River, a sight that shook the mortal world.
He saw only the power of billions of stellar rays descending from above, transforming into the stars of the heavens, reflecting upon the vast Luo River, as if merging into a brilliant river of stars hanging in the Ninth Heaven.
This scene was so spectacular and beautiful, breathtakingly so.
Circling both sides of the Luo River, one terrifying Demon King and Beast King after another appeared, each often larger than mountains, at the very least in the Heavenly King Realm, with many at the Great Power Realm. Ye Chen even saw several special, fearsome Demon Kings who did not take human form, but remained in their true bodies.
There was a Primal Dragon, a Mysterious Turtle, a Fire Sparrow, and a White Tiger, akin to the Four Great Saint Spirits of Heaven and Earth Creation, the four Demon Kings dwelling in the deepest part of the Luo River, exceedingly powerful.
Their sizes were only that of mountains, similar to some great demonic beasts of the Saint Realm, but in truth, these four Demon Kings were the most terrifying and dreadful existences within the entire Luo River Mountain Range. Even an Ancient Kingdom would not dare to provoke them.
Only those who truly knew the secret understood that the four Demon Kings, resembling the Four Great Saint Spirits, were all formidably powerful.
For in the past, a great battle had erupted in the Luo River Mountain Range. An Ancient Kingdom's Divine King Ancient Ancestor, having heard rumors that the legendary Immortal Emperor Medicine might exist within the Luo River Mountain Range, personally led an army to attack, penetrating deep into the Million Mountains. The result was that they vanished overnight, disappearing without a trace.
A few survivors who managed to escape alive back then proved that the Divine King Ancient Ancestor had been slain by the four Demon Kings resembling Saint Spirits.
This had also led to the scarcity of outsiders setting foot near this Luo River in the depths of the Luo River Mountain Range throughout endless ages.
Ye Chen stood atop a mountain peak, utterly silent. Even the four Demon Race Divine Kings could not detect his presence. He quietly observed this scene.
His gaze merely swept briefly over the four Divine Kings before settling upon the depths of the Luo River.
There, an immeasurably dark figure was faintly discernible.
"The Luo River. Legend says there is a special ancient herb within, an Immortal Emperor Medicine. It is said to have been personally planted by an ancient Great Emperor of the Mythological Epoch, watered daily with Emperor's blood, recited to with Emperor's scriptures, bathed in the light of the Emperor's Dao, growing over endless ages."
Ye Chen murmured softly to himself. This was a record from the Barbarian Tribe, a secret piece of information collected during the era of the Barbarian God Ancient Kingdom, but it was merely a rumor, not necessarily true.
Later, the Barbarian God King personally confirmed it was true. The Desolate Imperial Clan had records; there indeed had been such an Immortal Emperor Medicine.
However, having endured the Great Destruction of the Mythological Era, the ancient Great Emperor who planted that Immortal Emperor Medicine had also fallen. It was likely that the Immortal Emperor Medicine had mostly been destroyed along with him.
Of course, throughout this epoch, traces of this Immortal Emperor Medicine had appeared in various eras. The final record placed it within the Luo River Mountain Range.
"The Immortal Emperor Medicine. Legend says it is actually another form of existence of an ancient Great Emperor. Bathed in Emperor's blood, having listened to a Great Emperor's recitations, cleansed by the light of the Emperor's Dao, it has been in contact with everything related to an Emperor since its sprouting. In a sense, it can be said to be a supreme great medicine refined by an ancient Great Emperor, containing inconceivable wondrous effects. Its value is no less than a tenth-rank Emperor Pill, perhaps even higher, its creation peerless."
Ye Chen thought to himself.
Legend said that when an ancient Great Emperor was on the verge of falling, at the critical moment, the Immortal Emperor Medicine could even extend life, revive the Emperor's life force, allowing him to live a second life. It was a great life-extending medicine.
Similarly, precisely because such an Immortal Emperor Medicine was too heaven-defying, it was also exceedingly rare. Even among ancient Great Emperors, few possessed one.
Even colossi from antiquity like the strongest Emperor or an Immortal King might not necessarily own one.
Ye Chen suspected that if an Immortal Emperor Medicine truly existed within the Primordial Heaven Realm, it most likely belonged to a colossus from antiquity of the Pangu Universe, and that colossus might not have truly fallen.
Of course, as long as he obtained the Immortal Emperor Medicine, his injuries could be resolved in an instant.
"Regardless of truth or falsehood, even if the Immortal Emperor Medicine does not exist, merely taking a portion of the essence blood from these four Demon Race Divine Kings to refine a Four Saints Chaos Pill would be enough to greatly alleviate the injuries within my body." Ye Chen smiled. The four Demon Race Divine Kings were all descendants of the Four Chaos Saint Spirits from the era of Heaven and Earth Creation. Their essence blood would also have extraordinary effects for his current state.
Rumble—
The vast Luo River slowly churned, its endless waters flooding towards both riverbanks.
The Demon Kings and Beast Kings naturally soared into the air, retreating far away.
Then, within Ye Chen's sight, a soft, elongated, and immense figure instantly emerged.
It was so majestic and enormous, comparable to a mountain range, rising from the Luo River, shaking heaven and earth, causing the void to tremble, crack, and shatter.
Above, the stellar ray power, magnificent as billions of stars, instantly surged towards this soft, elongated figure, being devoured by it.
At this moment, Ye Chen's gaze instantly transformed from profound to blazing, radiant as the heavenly sun, illuminating the vast sky.
"Immortal Emperor Medicine!"
He uttered each word deliberately.
That aura contained wisps of supreme aura, yet it was not that of an ancient Great Emperor.
Similarly, within that soft, elongated figure, one could distinctly sense a life energy as vast as the sea, boundless as a sea of stars, limitless.
And when one truly saw clearly, that soft, elongated figure was not some dragon-like or snake-like existence at all. It was merely a section of vine, yet as grand as a mountain range.
Seeing such a scene, he believed this was the legendary Immortal Emperor Medicine.
Yet no one had ever said the Immortal Emperor Medicine was merely a tiny herb the size of a palm.
A towering, sky-piercing posture like a colossal tree was also entirely possible.
"Excellent. Truly, after searching far and wide with no success, obtaining it requires no effort at all."
Ye Chen stepped out from the mountain peak, no longer concealing his figure this moment.
"Roar—"
The Demon Kings and Beast Kings on both sides of the Luo River looked over, exuding strands of sharp, cold, and merciless intent.
Especially the four Demon Race Divine Kings were even more so. Their fearsome Divine King auras erupted, shaking the deepest part of the entire Luo River Mountain Range.
As if sensing something, that vine slowly sank back into the Luo River, seemingly about to vanish once more.
Ye Chen, neither sad nor joyful, actively walked forward.
Roar—
A Heavenly King Realm Demon King pounced over. A giant bear spanning hundreds of li swung a fearsome bear claw, slamming down fiercely.
This single slap would undoubtedly kill an ordinary Heavenly King.
Yet it could not even touch the hem of Ye Chen's clothes, as if they existed in different spacetimes.
In a blur of movement, Ye Chen arrived above the Luo River. Even the four Demon Race Divine Kings could not detect how he appeared, startling them.
"Come out, Immortal Emperor Medicine."
Smiling, his figure flashed, arriving at one of the vines of the Immortal Emperor Medicine that was slowly sinking. He reached out and grabbed.
Rumble—
Instantly, the entire Luo River violently shook, stirring up towering, terrifying waves.
