Although Ah Yin had sacrificed herself once, her soul remained. In theory, she could be considered a Hundred-Thousand-Year Soul Beast that had begun cultivating anew, though she was currently rather weak.
Given a suitable environment to grow in, Ah Yin could theoretically recover her hundred-thousand-year cultivation very quickly. Unfortunately, Tang Hao had planted her in this pitch-black stone cave.
And Tang Hao had undoubtedly gone with Tang San to the Soul Hunting Forest by now, so killing Ah Yin would be no challenge at all.
As for Xiao Wu, Bai Shu admitted that, having come from a civilized society, he truly could not bring himself to kill such a young girl. Besides, the risks were too high.
Even if he truly killed her, news of the Hundred Thousand Year Soul Bone would inevitably spread. If it drew the pursuit of Spirit Hall, even the Guardian he had never met might not be able to protect him.
Of course, there was one more crucial point.
He had a grudge against Tang Hao, and Ah Yin could be considered his future enemy. When dealing with an enemy, it was only natural to strike first.
Furthermore, the Hundred Thousand Year Blue Silver Emperor Left Leg Bone Ah Yin left behind was a treasure to him as well.
His martial soul, the Chaos Green Lotus, possessed the Ultimate Life Attribute, while Ah Yin was also life-attributed—and close to the ultimate level at that.
It could be said that on this continent, aside from Bi Ji, the Emerald Swan clan leader and fourth-ranked of the Ten Great Ferocious Beasts, there was no Spirit Beast more suitable for him than the Blue Silver Emperor.
Bai Shu traveled swiftly. Comparing his route with the map along the way, he arrived at the waterfall by evening.
Although the original work did not specifically state where the waterfall was, the area around Notting City was only so large.
There were only two waterfalls near Holy Soul Village, and one of them was merely a small waterfall, which did not match the height described in the original work.
Thus, Bai Shu had long learned the waterfall's approximate location by chatting with the villagers. Now that he also had a map, he naturally found it with great precision.
Looking at the magnificent waterfall before him, Bai Shu began searching for the so-called cave from the original work.
However, Bai Shu soon frowned. The waterfall's current was too rapid. With his current physical condition, he could pass through it for a short time, but enduring the waterfall's pressure while searching for long was simply impossible.
Moreover, if Bai Shu remembered correctly, the cave where Ah Yin was located was halfway up the waterfall, and Tang Hao had set up a mechanism to open it.
"This definitely won't work if I search bit by bit. I can only try another method."
Bai Shu began climbing up along the mountain path. The densely vegetated forest was difficult to traverse, and it took him quite a while before he finally reached the summit.
"I remember there was a small stone hole directly facing Ah Yin in the cave where she was kept. As long as I find it, I'll have a chance to kill Ah Yin."
The next moment, Bai Shu summoned his martial soul. A Green Lotus shrouded in chaotic aura slowly spun and bloomed in his palm.
Bai Shu took a deep breath, closed his eyes, and immersed all his focus within it.
As a martial soul of Ultimate Life, the Chaos Green Lotus had an extremely keen perception of life force.
Though its sensing range was limited by his Soul Power, the Blue Silver Emperor, a top-tier life-attributed Spirit Beast, would be like a beacon in the darkness to his senses. It could never hide from him.
Bai Shu carefully sensed with his martial soul while slowly moving across the mountaintop, his gaze meticulously sweeping over every rock beneath his feet.
Suddenly, a pure life force different from the surrounding vegetation appeared within Bai Shu's senses.
The quality of that life force nearly approached the Chaos Lotus Seed being nurtured within his martial soul, yet it carried an eerie weakness.
"How laughable..." Bai Shu shook his head with some pity. "With such pure life force, even if only a remnant root remained, it could rapidly recover with enough nutrients. Yet Ah Yin has been a seedling for six years and is still so weak. Tang Hao, it would be a waste of your talents if you didn't become a prison warden!"
Following the guidance of that life force, Bai Shu quickly found a stone hole set in a flat slab of rock.
The stone hole was only the size of a fist. Bai Shu lowered himself and brought his face close, peering inside by the cold moonlight.
At the bottom of the cave, roughly seven or eight meters away, a small grass plant, crystalline blue all over with golden patterns, swayed faintly and emitted a weak glow.
"Finally, I found it."
Looking at the little grass plant, Bai Shu let out a relieved breath. This location had only been his deduction, and he had truly feared he might have searched the wrong place.
"Tang Hao, did you think hiding her here would make her completely safe? Today, I'll collect a little interest first!"
"First Soul Skill, Life Link."
To avoid any accidents, Bai Shu went all out from the start. An emerald-green vine as thick as an infant's wrist extended through the stone hole in an instant, reaching the bottom of the cave and wrapping around the frail Blue Silver Emperor.
The next moment, Bai Shu directly controlled the vine to draw out her life force and replenish himself.
Buzz!
An exceptionally pure life energy surged madly into Bai Shu's body through the vine!
"What astonishing life force!"
It had to be said that the Blue Silver Emperor truly deserved to be the emperor of the Blue Silver Grass clan. Its vitality was so tenacious that even Bai Shu was stunned.
Ah Yin clearly looked as though she might die at any moment, yet Bai Shu forcibly drained her for two full hours.
At first, that pure life force wildly washed through every part of his body, strengthening his physique and making him feel as if he were overflowing with power.
But soon, this physical enhancement reached the limit of his current stage. Any more would become a burden, requiring time to digest.
Left with no choice, Bai Shu could only guide the ceaseless stream of life force entirely into his martial soul, converting it into nourishment for the Chaos Green Lotus as it began nurturing new Chaos Lotus Seeds.
One, two, three...
Within the lotus core, lotus seeds like emeralds condensed one after another, each containing ultimate life energy.
Only when the ninth lotus seed completely formed did that tenacious life force finally come to an end.
As the leaves of the Blue Silver Emperor in the cave curled up unwillingly, withered, and turned to ash, a notification that sounded like heavenly music to Bai Shu finally rang out.
[Ding, task completed.] [Task: Kill a Hundred-Thousand-Year Soul Beast. (Completed)] [Reward: One Super Douluo-level Guardian]
"Phew..." The task he had planned for so long was finally complete. Bai Shu let out a long breath, unable to suppress the wild joy on his face as he immediately chose to claim the reward.
[Ding, congratulations on completing this task. Reward obtained: Super Douluo Guardian: Xie Biyan] [Notice: The Guardian has been automatically converted to this world's cultivation system and possesses this world's basic common knowledge.]
"Excellent, a Super Douluo." Bai Shu clenched his fist excitedly. "Tang Hao, you dared to force me? Just you wait."
"But Xie Biyan... why does that name sound familiar, yet I can't remember where I've heard it?"
