"Should we be worried?" Aimy asked Irene who was currently drawing a seal at the base of a big crystal.
"I don't know," Irene replied.
"That's surprising, I expected you to have to run over some long ago, but so far you've been in control of yourself."
Irene heard Aimee's words, but rather than responding immediately, she sent out her soul sense, a complicated expression on her face.
"Though he's ignored my advice, so far he seems to be doing rather well."
"Rather well would be a severe understatement of his actions" Aimy snorted.
Currently, there was a light tremble in the cave, and the qi which usually saturated the cave was now all flowing in one direction, and not too far away, the loud sounds of a chaotic wind could be heard.
This was not the first or second time it was happening, but rather the third, and this was when one ignored the other minor times there had been a moderate change in the cave's qi flow.
It had been a day since Seth's first breakthrough, and now he was wroughting about a storm as he went about his third breakthrough, one which would make him a level 6 mortal cultivator.
Both sisters had headed over there the last time shocked to witness the phenomenon.
Like the first time Seth had been rather unaccommodating wanting to keep to himself, so the sister had let him be.
Now Seth was going through another major breakthrough, but the sisters weren't going to go over.
They were just going to accept Seth's abnormal breakthroughs and continue with their work, after all, unlike Seth, they had crystals to harvest.
Close to an hour passed, and both sisters worked, only their soul sense sweeping over Seth when he was done with his breakthrough and when they saw he was all right, they went about their business.
Minutes and then hours went by, and just when the sister thought Seth was done with his breakthroughs and was now consolidating his level, they noticed another change in qi airflow.
While this qi flow wasn't prominent, its presence still indicated that Seth was progressing through a minor rank, and the sisters couldn't help but look at each other in surprise.
"Seems he'll clear the entire level," Aimy said with a bit of daze.
"How does he even do it" she continued.
Hearing Aimee's words, Iren could only let out a wry smile. Though Irene knew about Seth not being a human, he had never told her his specie, and neither did she know.
With how broken his cultivation speed, was, Irene could only assume it was due to some traitorous encounter or some deadly cultivation technique.
Had Seth's cultivation prowess been a result of his race, then surely, she would have heard of it.
With thoughts of amazement about Seth in their mind, both sisters went about their work, and it wasn't long before they were finished.
With its deadly qi, the cave was not particularly a safe and convenient place for cultivation, so the sister could only languish around and wait for Seth to be done.
During their relaxation, Seth changed the qi flow of the cave one more time, but by then the sisters had gotten used to his abnormality, even doing several guesses on long it will take him to break through a minor stage.
With the last minor breakthrough completed, both sisters were ready to depart, absolutely confident that Seth was finally done with his abnormal breakthroughs and that at the moment he was settling down from his long series of advancements.
An hour later, both sisters were still idly waiting for Seth when they both suddenly sat up straight.
Though the cave had already been silent and void of life, at that moment, it suddenly gained a new level of serenity and stillness that wasn't there before.
The chaotic qi which has always been in the air and randomly moving around standstill, and the feeling of being watched gnawed at everyone's senses.
"This feels familiar," Irene said looking around in confusion.
While Irene was filled with doubt, Aimy who had interacted with the feeling more recently instantly got the answer.
"Breakthrough."
"No it can't be a breakthrough, for Seth to progress any further, he needs to communicate with the heavens, and for him to do that, he needs to have his first comprehension.
So you see there is no way it can be a breakthrough, and I shouldn't have to be explaining this to you" Irene berated, getting to her feet as she tried to trace the weird sensation she was feeling.
"No, it's breakthrough" Aimy insisted, and just as Irene wanted to scold her, the cave suddenly began quaking.
Seth's previous major breakthroughs had caused the cave to slightly tremble, vibrating at a very low frequency, but what was happening now was different.
As cultivators, Aimy and Irene easily kept themselves standing, their eyes cautiously watching the crystal around them vibrate.
"Impossible" Aimy muttered several times, while Irene's face scrunched up in confusion as she tried to understand what was happening refusing to believe Aimy's claim.
"To even be able to carry out the first comprehension, he had to be at the peak of the previous rank, but it's just been an hour since his breakthrough, he hasn't even had the time to comprehend anything" Iren muttered, but the next second her doubts were wiped out as an undeniable truth of Seth breakthrough was presented before her.
Taken unaware, both Irene and Aimy were sent falling to their knees when Seth's spirit sense suddenly came erupted with great pressure and slammed into them.
"He's breaking through" Irene finally muttered as Seth's spirit sense rushed back into him and then came out again.
Like a wave Seth's spirit sense spilled back and forth, and though both Irene and Aimy had gotten to their feet and deployed their soulsense around themselves, they still felt uncomfortable when Seth's transforming spirit sense rummaged around them, wanting to rampantly peer into their being.
