In no time at all, Cain and Kali safely made it back to the original cave they had teleported. As they half expected, the ones following them still didn't make any attempt at attacking them.
At this point, the sibling duo assumed those people were attempting to scout them out for whatever reason.
There was a potential of danger within this situation. After all, Cain and Kali could sense the one's following them wasn't weak.
However, neither Cain nor Kali felt cautious or fearful.
A slight sense of exhilarating excitement slowly bubbled within their minds. They were sure the one's following would attack them sooner or later. And when it happens, they expect a greater fight than those vicious beasts.
Whatever being following would give the sibling duo their authentic combat experiences on this Mortal Planet!
As of now, Cain and Kali didn't waste time while waiting for the presences to show up. Immediately when they got to their cave, they turned to cultivation.
Within seconds they enter their cultivation state, absorbing Spirit Qi from the air and circulating the energy inside them.
Afterward, only a mere five minutes passed.
But at it was that mark, both Cain and Kali felt their cultivation already reached a critical juncture! Despite only cultivating for literal minutes, the sibling duo was already nearing a breakthrough!
Even though Cain knows his cultivation is fast, it shouldn't be this fast.
This speed was simply breaking all rules of cultivation. If anybody were to witness this, they would be frightened to their cores.
Cain could only reasonably assume because of their recent fight, it was pushing him to quickly breakthrough. Perhaps through actually using Spirit Qi for fights, the dragon charm subtlety activated?
It was an intriguing thought, especially as he could sense Kali similarly reaching a breakthrough. She undeniably has a slower cultivation speed than him, so Cain pinpointed it all towards the Dragon Charm.
However, Cain soon took his focus off from this. Answers could come later; for now, he focused on completing his breakthrough.
With little to zero resistance, Cain pushed right through the invisible barrier blocking him from reaching the fifth level of the Spirit Opening Realm.
'Ka-Cha!'
A powerful shattered jolted Cain's entire being. Spirit Qi rapidly infused in his tendons, bringing up his percentage of completion to seventy percent!
Just like that, Cain achieved yet another breakthrough.
Now, he felt even more monstrously stronger than before. Cain felt like if he faced those vicious lions and black fur bears again, he could crush them all without Kali's help.
His dense Spirit Qi circulated throughout his tendons like smooth water, showing zero traces of disrupted balance. While on the outside, a small whirlpool of Spirit swirled at the top of Cain's head.
With his newfound breakthrough completed, Cain took only a few seconds to adjust his power. He quickly calmed his boiling blood, itching to go out and experience another fight.
Feeling entirely calm, Cain swung his eyes open, and the whirlpool above his head vanished.
At that moment, before Cain could process his next move, his Soul Sense detected a significant change within Kali.
Only seconds after he finished his breakthrough, Kali's Spirit Qi had entirely changed once again.
Now, she made it to the fourth level of the Spirit Opening realm!
And though she is weaker than him, Cain could still feel a powerful energy radiating from her.
But before that powerful energy got too loose, Kali quickly reigned it in. Afterward, she flung her eyes wide open; an abundance of joy was plastered on her face.
Snapping her gaze over to Cain, Kali spoke with a broad smile.
"Ah-ha! I had a feeling this would happen! Previously, it nearly slipped my mind because I don't know how to work this thing, but the Dragon Charm rapidly pushed us to a breakthrough after that fight."
All thoughts and suspicions swirling within Cain's mind were confirmed at that moment.
So it really was their Dragon Charm!
Really, this thing was an actual cheat for their cultivation. However, a new set of questions suddenly enter Cain's mind over this revelation. He decided to ask,
"I see, but did grandfather ever explain how this exactly works? And would it always be this easy for future levels?"
"Hmmm….let me see…."
Kali's expression briefly lit in ponderance for a few seconds before continuing on to say, "Well, grandfather claims because it's our specific bloodline, the dragon charm will respond to our wishes. He never really gave detailed instructions. After all, we were basically useless in cultivation just hours ago. As for later levels….most likely not. Grandfather vaguely explained starting from even the Profound Soul realm, there are many aspects to achieving breakthroughs."
Cain crossed his arms, taking in Kali's words. It seemed there's a lot of things he and Kali don't know about their Dragon Charm.
And since it responds to their bloodline….several ideas popped into Cain's mind.
But before he could contemplate those ideas, Cain and Kali quickly snapped their attention to the cave's entrance. Their Soul Senses detected that several presences finally decided to make themselves known.
Loud, uncaring footsteps began to make their way into the cave, and soon enough, the one's following from before appeared.
"You two! Don't resist if you don't want to die and come with us."
As soon as they appeared before the sibling duo's eyes, an arrogant sounding voice shouted to them. The young man's voice was laced with a slight chill of Killing Intent, showcasing he's entirely serious about his words.
Cain and Kali simply sat calmly while sizing up the presences before them.
It was three young men all wearing brown leather armor and brandishing straight silver swords. Each of them had an entirely arrogant posture as if they already knew how this situation would end.
On their faces as well were an attempt at a fierce expression, wanting to intimidate anyone by looks alone.
In the face of these sudden intruders, Cain and Kali took one brief glance at each other.
A spoken signal crossed between their eyes. Previously, the sibling duo felt some amount of danger from these men.
But now?
They barely felt any danger, and their intention to battle was quickly rising. Then, in a completely calm manner, Cain and Kali stood up.
Not showing any kind of expression, Cain slowly asks, "Come with you? Just why should we do that, and who exactly are you?"
"Since you're ignorant, we have an obligation to properly explain."
The brown leather armor man who spoke first opened his mouth again. His expression turned condescending as he continued to say,
"We are from the Liang Tribe. One of the strongest powers around these woods. And as of now, our tribe requires some slaves. That's all you need to know. Now then, obediently come along, and you won't have to experience any pain."
Hearing their explanation, on the outside, Cain and Kali kept their calm expression. But on the inside, the sibling duo felt a slight sensation of pure anger surge.
Somebody actually dares to make them slaves?! There's no way even their bloodline could accept such a ridiculous thought!
Cain was feeling even more peeved off than Kali. He never wants to be tightly controlled by anybody ever again.
Furthermore, these leather armor men were simply too unreasonable. Just with their first meeting, these guys will either kill them or make them slaves.
Cain was well aware people in this universe are merciless. But experiencing it for himself allowed him to truly begin to feel despisement for arrogant people in this universe.
It was at this moment, Cain had decided on his next target.
No way in hell would he be anyone's slave. Moreover, these leather armor men had just confirmed they would either injure them or kill if they resisted.
A dignified look crossed Cain's face as he thought, 'For what's going to happen next, they would have only themselves to blame!'
Right then, instead of responding to the Liang Tribe's men, Cain snapped his gaze back over to Kali again.
"Are you ready?" He loudly spoke in an uncaring, cold tone.
"After you." Kali's expression and tone were similarly icy as she matched eyes with Cain.
At the same time, the Liang Tribe men condescendingly shook their heads at the sibling duo action.
The man in the center, the one who keeps on talking, the trio leader, pointed his sword straight at the sibling duo. Then, he began to gather his Spirit Qi, and his other two partners followed in his footsteps.
The leader dangerously narrowed his eyes on the sibling duo as he started to say, "Tch, you two don't realize your position, huh? Then don't blame us if we end up-"
'Hua!'
Whatever contempt words the leader had would never be heard.
As right in the middle of his spiel, Cain and Kali burst forward at immense speeds!
A fierce gust of wind whipped past the Liang Tribe's men, forcing them to squint their eyes.
Fast, it was too fast! Cain's speed was a blur in the leather armor men's eyes; they couldn't react at all.
Without losing his momentum, Cain flashed right near the leader and swung both of his fists out!
Dense Spirit Qi filled his fist, causing both the leader and the man to his right side to feel an incredible sense of crisis. In a desperate attempt at defense, they raised their swords to block but was a step too slow.
'Bang, Bang!'
"Arrg!!"
Two miserable wails echoed out, accompanied by two streaks of blood.
The two leather armor men were flung like ragdolls as Cain's fist caved their chest in, sending them crashing right into the cave walls.
"Wha?!?"
The only leather armor remaining standing was utterly bewildered. He wanted to process what had just happened but wasn't given any chance to do so.
Not when Kali appeared within a mere foot from him!
"Die!" On pure survival instincts alone, the leather armor men frantically thrust his sword straight at Kali.
Even though Kali was slower than Cain, she was still incredibly faster than these leather armor men.
With a crazed smile splitting across her lips, she easily dodged the man's sword and struck her fist squared on his chest!
'Bang!'
"Arrg!!"
Another groan of agony bounced off the cave's wall as the leather armor man got sent flying like a cannonball.
Blood gushed out of his mouth like a crimson stream as he brutally crushed deep into the cave's wall.
All in just a second, silence returned to the cave.
Cain and Kali indifferently tossed their eyes at the brutal scene. Slight disappointment flashed on their faces before quickly squashing it down.
The three leather armor men stayed embedded into the walls, clutching their chests as copious amounts of blood flowed out of their mouths. None of the Liang Tribe men could understand what was going on.
Their minds were reeling, thinking, 'how could this pretty boy and girl be so powerful!!'
Indeed, these three were following the sibling duo for some time now. However, none of them saw their fight with the vicious beast.
Initially, they believed the sibling duo had some sort of background going off their gorgeous faces and confident stature. But when they realized the sibling duo were just a pair of homeless cultivators, they all thought it was easy picking.
Never could they have expected for mere Spirit Opening cultivators to erupt with this level of strength!
The leader especially was cursing himself. His mind frantically wrapped, trying to ignore this mind-destroying pain and see a way out of here.
But right at that moment, a sickening thump boomed into his ears.
'Chi!'
Against the unbearable pain, the leader snapped his attention over to the noise. And his pupils dilated in utter horror.
Right in front of the leader's eyes, Cain indifferently stood over one of the leather armor men.
Cain's right fist was stained with crimson blood as he had just smashed it upon the leather armor man's head! The man's head was now utterly mutilated, having only pieces of flesh and bones while blood pooled out of him.
Without any hesitation at all, Cain killed his first ever human being!
