Admittedly, Cain and Kali didn't have that roaring drive to engage in a full-frontal collision. In fact, the sibling duo was genuinely worn about by now.
Beads of sweat swoll down their foreheads as heavy exhaustion takes over their bodies.
Because of their firm Martial Hearts, they weren't gasping over for air or struggling to stand. But the bodily exhaustion was still enormous.
To use Qi, Spirit, and Astral Energy all at the same time while combining it into their Martial Skill was an immensely draining feat.
At most, they had 10% of their entire energy reserves left.
Thinking of this, Cain realized this girl must've noticed the exhaustion within their faces, prompting her to ask if they could continue.
At this moment, Cain analyzed the whole situation. Covering his Spirit Sense over the Demonic Orge, Cain perceived that it was only its last dregs.
The beast may have got back up, but it could barely move. Only by its own sheer Will power could it hop back on its feet.
With just this, the Demonic Orge wasn't a significant threat. Hell, Cain fathoms he and Kali could easily outrun the beast if they so, please.
However, killing this beast would give him and Kali much better rewards.
Then, sweeping his Spirit Sense over himself and Kali, he estimated they could unleash only one more powerful combined attack.
It would obviously be far weaker. But combining with this silver-haired girl's prowess, Cain believed they could finish the kill.
All these thoughts swirled in Cain's mind within a moment. His brain was enhanced enough to process at rapid speeds. In this instance, he near instantaneously arrived at his conclusion.
As he did so, Cain tossed his gaze over to Kali. Their eyes matched, and Kali wordlessly nodded.
She clearly knows it's always better to go with whatever Cain analyzed in that cranium of his.
Seeing the confirmation in her eyes, Cain snapped back over to the silver-haired girl. This whole process merely took a couple of seconds.
Cain then nodded at the girl, telling her, "We have enough for one more attack, so we need a clear opening."
"No problem." The silver-haired girl faintly smiles. She leaned more into the tree and snapped her head over to the struggling Demonic Orge.
A familiar cold light sparked within the girl's eyes. At the same time, a powerful Aura gushed out of her like a violent tempest!
Strong winds swirled around her, spreading out everywhere as vigorous energy erupted out of her bewitchingly curvaceous body.
'Mn! So this is Profound Soul power!' Cain and Kali's eyes instantly brightened.
This girl's energy was more powerful than they had previously perceived!
Now, they felt a considerable sensation of pressure wracking their bodies. It felt like they were training in the Stormy Wind Tunnel again.
If Cain and Kali were at full strength, they would be able to deal with this weakened Aura far easier.
But with their current limited reserves, it was a bit of a struggle to withstand the genuine power of a Profound Soul expert.
Still, Cain and Kali didn't lose themselves because of their shock. They diligently summoned the last bit of energy flowing throughout their internal bodies.
At the same time, the silver-haired girl raised her palm, amassing a great force of energy.
Shades of Darkness suddenly began to engulf the area.
Upon the silver-haired girl's palm, an abundance of Darkness energy gathered, shrouding the entirety of her hand.
The instant the Darkness energy formed, it bubbled like boiling lava. Then, several streams of shadow tendrils burst out of the bubbling Darkness energy!
The shadow tendrils were amazingly quick. They were virtually beams of backlight soaring through the air, reaching the struggling Demoninc Orge within seconds.
The shadow tendrils were too quick for the beast's current state.
Without any resistance, the Demonic Orge was wrapped entirely up in the shadow tendrils!
"Ga-Gaa!!"
Cries of frustration and pain wailed out of the Demonic Orge. The beast struggled to escape, but it was only met with immense pain.
Wrapped up in the shadow tendrils, the beast felt its blood getting forcefully ripped out of its body and absorbed into the shadow tendrils!
The pain of getting one's blood ripped out was worse than getting one's limbs brutally hacked off. Not only did the Demonic Orge experience this hellish pain, but it also felt its already little strength rapidly leave it!
In this situation, the beast really was on its last leg.
And at that moment, Cain and Kali attacked!
Light shined from their palms as the sibling duo gushed out powerful Elemental energy palms.
Lightning and Ice energy interwove together, releasing a power that's beyond their usual might. Amplifying this attack was the addition of Spirit Energy.
Even with their energy reserves nearly drained, Cain and Kali could still erupt with such ferocious strength.
Against the sailing Elemental Energy palms, all the Demonic Orge could do was helplessly watch on. Under the silver-haired girl's suppression, its life was forfeited.
'Bang!'
The Elemental energy palms utterly crushed the Demonic Orge's massive head, causing droplets of dark red blood to sprinkle all over the area.
Under constant weakness and previous injuries, all of the Demonic Orge's defenses crumbled to dust.
A mighty Profound Soul beast died at the combined hands of two mid-ranks Nascent Formation youths….
If anyone were to know about this, the storm it could cause would be utter chaos!
'Bang!'
Once the Demonic Orge was dead, the shadow tendrils dispersed, allowing the beast to crash right onto the ground.
"Huu~. At least it wasn't too troublesome to finally kill it off." The silver-haired girl lethargically sighed. She was most glad about being able to take it easy now.
Turning her attention back on Cain and Kali, the girl gave the sibling duo a lazy yet beautiful smile.
She said, "Really, if it wasn't for you two, I may have ended up with a broken limb or two or even worse. You have my sincere thanks."
The appreciation within her tone couldn't be understated. Even for all her lethargicness, this silver-haired girl can genuinely show gratefulness.
This only made Kali slightly narrow her eyes. She curls her brows in brief contemplation.
'All Mortals would be at least somewhat shocked over us. Even the older Mortals were. So why isn't she….?'
For the first time since coming to the Heaven Sky Planet, a mortal aroused Kali's intrigue.
This girl didn't seem like she was some old veteran cultivator, having shelved a lifetime of harsh experiences. She's merely some Profound Soul Mortal Talent.
Still, her countenance could be said to rarely be seen. At this moment, ideas began to swirl within Kali's mind.
At the same time, Cain spouted off a clean, faint smile as he asked the silver-haired girl, "It really wasn't any problem for us. We more so did this for our own gains more than anything. So what's your name anyway?"
The silver-haired girl paused, slight curiosity gradually building her face. She tilted her head just a bit and then started to inch closer to the sibling duo.
A thought streaked in her mind, and she answered, "My name is Amber Hiyashi. Yours?"
Throughout this entire time, Amber had, of course, noticed Cain and Kali's uniform. These two weren't any sort of standard batch.
They were genuine Martial Talents!
Because of the waves of students at Crimson Sea Academy, it was impossible for Amber to know every good individual talent in the ranking list.
However, it's almost too easy to recognize students who made huge names for themselves.
So far, Cain and Kali went entirely against her expected reaction. And now, when she finally told her name, she partially expected something different.
However, even as she fully broadcasted herself, neither Cain nor Kali even twitched their expressions.
Kali still held her look of utmost superiority. Though Amber could tell there was an odd glint sparkling within her eyes.
While Cain still had his calming, faint smile.
Just from their reactions, Amber felt her intrigue grow more than what it already was. Today really is full of surprises for her.
"My name is Cain, and this is my sister Kali. We actually just got done finishing the Demonic Golden Wolf mission before we rushed over here." Cain took the role of introductions once again.
Before replying, Amber got even closer to the sibling duo. Without them realizing it, she got to a point where she was only merely five feet from Cain.
Cain didn't react, but Kali was sure to take particular notice of this closing invasion of personal space.
Amber was still softly smiling as she finally said, "My, my. I've heard about that mission. A lot died thinking they were greatly prepared to take on rowdy beasts. A bit of a shame about them. You two, however, seem like you're more than just prepared. Not a single scratch on you or even slightly frizzle hair."
"Well, as you saw before, our combat prowess isn't anything ordinary."
"Fufu~." Amber sweetly giggled. "That's an understatement of the century. I can already tell the oldies, and all others have numerous sets of eyes on you."
As he was going to answer back, Cain tossed a look over their whole area. He asked, "By the way, just what were you doing out here? A mission to exterminate beasts as well?"
"Huu~. No way I would choose something so time-consuming. Actually, my mission was to simply collect some rare flowers without getting them damaged. It was supposed to be more of a low, sneaky mission. But, you saw how that ended up."
Amber lazily stretched and then gestured to the enormous Demonic Orge corpse. "So? Do you want to take all of those Cores? I don't care at all about them. Actually, just go ahead and take them. You might as well get all of your hard work rewarded."
Hearing this, Cain and Kali were slightly startled. Admittedly, they expected they would need to reason with Amber to gain some of these spoils.
But it either seems like her mind is open-ended. Or she's too lazy to care about spoils.
Cain had a feeling it was the latter option. In any case, he had no real reason to refuse. This was what they were here for in the first place.
Right as Cain was going to speak, Amber suddenly spoke up again, flashing Cain a more tired smile. "Say, when you're done with this. Wanna walk back together? It's too dull to be on your own in this dark place."
"Sure, why not? This won't take long anyway."
Cain promptly nodded and then went to go collect the Profound Soul Core.
