Soul-Cleansing Divine Water, Undying Essence Liquid, and Life Elixir — the three great divine waters.
Among them, the birth of Soul-Cleansing Divine Water was a matter of chance and coincidence. A powerful being had to perish, their divine soul's power lingering undissipated at the place of their fall. Only through natural fortune could Soul-Cleansing Divine Water possibly come into being. Though rare, it was not entirely extinct.
The remaining two, without exception, were treasures nearly impossible to find.
The Life Elixir was one thing — perhaps in some hidden corner of this Star Boundary, such a substance existed, though no one knew of it.
But the Undying Essence Liquid… there was simply nowhere to seek it.
Because the Undying Essence Liquid was a derivative of the Ageless Tree! It was the Ageless Tree's life essence!
A single drop of Undying Essence Liquid could regrow white bone and revive the dead, possessing heaven-defying, extraordinary efficacy.
The sole Ageless Tree in all the world had been planted by Yang Kai in his own little medicinal garden. Others naturally had no way to obtain the Undying Essence Liquid.
The drop he still held was a remnant from when he had first acquired the Ageless Tree all those years ago — he had never been willing to use it!
Offering such a heaven-defying treasure in exchange for a Calamity Tribulation Fruit — surely no one would refuse.
The only thing to worry about was whether the appearance of the Undying Essence Liquid might attract some other kind of trouble.
But for the sake of the Calamity Tribulation Fruit, he could no longer afford to worry about that. If anyone asked questions when the time came, he could always play dumb. No one would likely think that a supreme treasure like the Ageless Tree would be in his possession.
Having made up his mind, Yang Kai sat cross-legged and waited in silence.
There were still five or six days remaining. The warriors who had entered the Four Seasons Domain were in no hurry to leave — at this moment, they were likely still searching for their own opportunities throughout the land. As a result, the area near the entrance was utterly tranquil.
Time drifted by. After a full day, the plain where the entrance lay still held only Yang Kai. Not a single other person could be seen.
Then, without warning, Yang Kai's brow furrowed. He opened his eyes and gazed in a particular direction.
In that brief instant, he had sensed an unusual pulse of energy — flickering and vanishing in the blink of an eye!
But when he looked toward the direction from which the energy had come, he detected nothing at all. A flicker of doubt crept through his mind. Perhaps he had imagined it.
Just as he sat pondering, a layer of light suddenly rippled outward from a point far in the distance.
The halo was almost solid, expanding outward in every direction like ripples on water.
Yang Kai rose abruptly to his feet, narrowing his eyes to study it.
Ahead of him, roughly a hundred li away, atop a mountain peak, the halo surged outward in continuous waves. At first, it was a single, uniform color, but as time passed, the light gradually shifted into a dazzling kaleidoscope of five brilliant hues.
Not only that — the spiritual energy between heaven and earth in that direction seemed to be churning and surging. Above the mountain, multicolored auspicious clouds churned restlessly across the sky, lending the entire heavens an otherworldly, almost eerie appearance.
"Heavenly phenomenon!" Yang Kai exclaimed in a low voice. "A rare treasure is emerging!"
He didn't know exactly what was happening over there, but judging from the current situation, a rare treasure was unquestionably being born — and not an ordinary one, either. Otherwise, its emergence could never produce such a conspicuous phenomenon.
"Why now, of all times…" Yang Kai's brow knitted tightly, his expression darkening.
There were only four or five days left before the exit of the Four Seasons Domain closed. If all had gone as expected, the disciples of the various great Sects would have already begun making their way back.
And the location of this phenomenon was a mere hundred li from the exit.
In other words, the heavenly phenomenon from this emerging treasure would very likely attract a great many people. Moreover, the longer it persisted, the more would be drawn in! An inevitable scramble for the treasure would ensue, and blood could very well flow like rivers!
When that happened, his plan to trade the Undying Essence Liquid for the Calamity Tribulation Fruit would certainly be disrupted.
So when he first saw the heavenly phenomenon, Yang Kai's initial reaction was not excitement, but vexation. The timing could not have been worse for him.
Yet despite his silent complaints, the phenomenon had already grown far too conspicuous for him to ignore. Naturally, he had to go see it for himself!
With that thought, Yang Kai summoned the flying wooden boat, stepped aboard, and channeled his Source Power. The boat shot forward in a streak of light, hurtling toward the source of the phenomenon.
The boat was incredibly fast — a hundred li was covered in a matter of a dozen breaths. And as the distance closed, Yang Kai caught a strange fragrance wafting through the air between heaven and earth. The scent filled his nostrils and refreshed his spirit, like an epiphany washing over his mind…
"Is it a rare medicinal herb?" Yang Kai made the judgment silently. Moreover, it was the kind that could aid a warrior's Cultivation, for as the fragrance entered his nostrils, he could faintly sense that the bottleneck at the first level of the Dao Source Realm was beginning to loosen!
He had only recently ascended to the Dao Source Realm. Despite the constant battles and diligent Cultivation of recent days — not to mention the opportunity he had gained on the Steps of Time — he was still some distance from breaking through to the second level. Yet now, that gap had suddenly narrowed considerably. The heaven-defying efficacy of this rare herb was truly astonishing.
