The Ice and Fire Yin-Yang Well.
One of the three great treasure troves, its formation has always been a matter of debate.
However, the most reliable theory holds that two of the Nine Great Dragon Kings—the Water Dragon King and the Fire Dragon King—fell simultaneously at this location. The power they left behind gave birth to the Ice and Fire Yin-Yang Well.
If that's true...
Then beneath the Ice and Fire Yin-Yang Well lie the remains of the Water Dragon King and the Fire Dragon King.
And indeed, this is the truth.
Back when Li Yu used the "Spirit Elemental Domain" to take the Ice and Fire Yin-Yang Well away, he had sensed this.
Because logically, their bones shouldn't be buried so shallowly. After all, when he "dug out" the Ice and Fire Yin-Yang Well, he only went down about a hundred meters.
Now, the massive pit at the center of Sunset Forest has been filled up again due to rainfall.
So, how did Li Yu discover the remains of the Water and Fire Dragon Kings?
At the very last moment when he was retrieving the Ice and Fire Yin-Yang Well, the power of the [Elemental Spirits] surged forth.
It was that surge of power that "drew out" the remains of the Water and Fire Dragon Kings.
In reality, the remains of the Water and Fire Dragon Kings were not buried in the conventional sense at the bottom of the well.
Rather, they existed in a spatial context.
It was akin to how Li Yu had entered the Holy Church altar in the Star Dou Forest—it was within a "missing" spatial pathway.
Merely "digging three feet down" would never uncover it.
It was precisely due to the power of the [Elemental Spirits] that Li Yu—who at that time had not yet mastered spatial power—was able to "grasp" that spatial structure through the "Elemental Spirit Domain."
Similarly—
That's why, after finishing the retrieval, Li Yu stood silently over the giant pit.
His consciousness was not only admiring the Ice and Fire Yin-Yang Well within the Elemental Spirit Space but also gazing upon the quiet, hidden spatial threads within the well where the remains of the Water and Fire Dragon Kings rested.
Their dragon souls had long dissipated, but their bones remained.
More importantly, there were two particular bones among them, radiating two extremely contradictory forces.
They were the true Ultimate Fire and Ultimate Ice!
Namely: [Annihilating Flame Fire Dragon Right Arm Bone] and [Frostscar Water Dragon Left Arm Bone].
These soul bones not only contained immense power, but were also the very core that allowed the Ice and Fire Yin-Yang Well to function.
Therefore, even though Li Yu discovered these two absolutely top-tier soul bones, he did not immediately collect or absorb them.
However, after the incident involving the descent of the "Sea God," Li Yu perspective changed.
At present, leaving such a treasure unused was wasteful, perhaps even foolish.
More importantly, it needed to be converted into power he could control.
And so, in the end, he absorbed both soul bones—
[Absorption Complete!]
[Undergoing Transformation...]
[Transformation Complete!]
[Soul Bones] —
[Spirit Annihilating Flame Right Arm Bone] – God Rank
Annihilating Flame Dragon Soul: Summons the soul of the Annihilating Flame Fire Dragon to wield the power of Ultimate Fire in battle.[Spirit Frostscar Left Arm Bone] – God Rank
Frostscar Dragon Soul: Summons the soul of the Frostscar Water Dragon to wield the power of Ultimate Ice in battle.
[Spirit Schedule: 8/10]
[Level: 80]
[Free Allocation Years: 287,000]
With this—
Li Yu soul power was directly pushed to level 80. Of course, this was not the limit.
However, in order to maintain the continued "operation" of the Ice and Fire Yin-Yang Well, he infused most of the "excess" power into the spatial structure where the remains of the Water and Fire Dragon Kings were stored.
Going forward, he would need to periodically infuse the power of the Annihilating Flame Fire Dragon and the Frostscar Water Dragon into it to keep the Ice and Fire Yin-Yang Well functioning.
Because of this—
Even though he absorbed the two Dragon Kings' soul bones, it did not affect the continued existence of the Ice and Fire Yin-Yang Well.
In fact, now that the well was within the [Elemental Spirit Domain Space], it operated even better than before!
One could say it was a win for everyone.
Li Yu soul power rose to level 80, and his [Spirit Schedule] had only one remaining major challenge.
"8/10."
Among the conventional body parts, the only missing one was the right leg bone—which was not difficult to find. The final challenge was the External Soul Bone.
External Soul Bones...
As of now, Li Yu had two leads that could potentially yield an External Soul Bone.
First, the Dark Gold Dreadclaw Bear.
The External Soul Bone of the Dark Gold Dreadclaw Bear—[Dark Gold Dreadclaw]—had appeared multiple times later in the timeline.
If he went into the Star Dou Forest to search, Li Yu believed there was a decent chance he could find one.
After all, if the Thorn Dragon had already appeared, the Dreadclaw Bear couldn't be far behind.
Second, Hu Liena.
Hu Liena possessed an External Soul Bone—though its exact name was unknown, it manifested as a giant fox tail.
This was revealed during the events after the Soul Master Tournament, when Tang San and Hu Liena met again in the Slaughter City, and she exposed it during the Hell Road trial.
However, because of its appearance, Li Yu was somewhat resistant to the idea.
Even though it was a rare and valuable External Soul Bone, he never considered taking it by force.
More importantly, at this point in time, he and Hu Liena had no grievances between them.
He would never go so far as to kill someone just for treasure.
Of course, if it were Tang San, he might not be so hesitant.
But that's a story for another time.
What Li Yu was more concerned with was the changes that occurred after absorbing the two Dragon King soul bones.
First, the Water and Fire elements—
The powers within these two elements had become significantly stronger, even emanating a faint aura of pressure.
This was different from his previous advantage over the Heaven Dou Imperial Academy's Skywater team, which came from his high elemental affinity.
If they were to meet again, the members of the Skywater team would likely find that their own water-element soul power would tremble violently under his command of the element, becoming hard to control.
The same applied to the fire element.
This had even surpassed the typical suppression that Ultimate Fire had over normal flames.
Furthermore, his first and second spirit rings had undergone another color transformation.
The first spirit ring, after absorbing a trace of the "Authority of the Sea," had turned sky-blue—now it had become ice blue.
The second spirit ring, originally a red ten-thousand-year ring, had become a deep crimson.
Additionally—
The [Spirit Annihilating Flame Right Arm Bone] and [Spirit Frostscar Left Arm Bone] had now become the only two soul bones in Li Yu possession classified as God Rank in terms of age.
After some testing, Li Yu discovered he could no longer inject free allocation years into these soul bones.
In other words, God Rank was their absolute limit.
This was also the upper bound that free allocation years could affect.
The exact requirement to reach "God Rank" was unclear, but most likely, it was achieving one million years.
What does that mean?
After reaching level 80, Li Yu could gain 4,000 years of free allocation time per day. Reaching 1 million years would take over eight months for just one soul bone.
Which means, if Li Yu wanted to push all his soul bones to the limit, it would take roughly ten years.
Not long, but not short either.
"Still a long road ahead…"
Li Yu sighed.
The darkness before his eyes faded away, replaced by a thick, natural aura.
He had arrived—
The Star Dou Forest.
