While the Battle God Palace's Extremity-rank Battle Masters were still stunned by their young master's guess, they did not notice the decreasing number of Lesser Demons in the Bone Sea.
Leon continued to alternate between cultivation and hunting demons while the dark faes practiced the Godfiend Body Forging Method in the medicinal bath.
By the time Leon hunted another 200 Lesser Demons, Saresha and the rest of the dark faes had depleted the effect of the medicinal bath.
During that time, Saresha and the other dark faes made a fair bit of progress.
Despite that, they weren't exactly sure how much stronger they had grown physically without testing their strength.
"Ah, the medicinal bath's effectiveness has been depleted! We can finally stop!" one of the dark faes rejoiced after making the discovery.
Saresha and the other dark faes also stopped absorbing the Lesser Demon-level demon core's energy after sensing the loss of recovery.
"I wonder how powerful we've become after practicing this Godfiend Body Forging Method…" Saresha muttered while clenching and relaxing her hands to feel the strength coursing through them."
"How about a light spar to find out?" another dark fae suggested.
"That sounds like a good idea since we can't continue to practice after the medicinal bath depleted its effectiveness."
"Yeah! I'm kind of glad it did! I never thought that I would say that but, this sort of cultivation is just torturous and unbearable!"
The dark faes chimed.
"Why have you all stopped cultivating?"
Suddenly, Leon's voice startled them; they quickly turned towards the source before they saw Leon returning from the Bone Sea's direction with a leather bag in hand.
"M-my lord!" they greeted.
While covered in demon blood, Leon hurled the leather bag to the side of the medicinal bath before numerous Lesser Demon-level demon cores, and some Greater Demon-level demon cores spilled out.
The dark faes were even more startled by the sight before Saresha quickly answered Leon's question, "The medicinal bath's effectiveness has been depleted, my lord!"
"I see," Leon calmly nodded before saying, "Let's review your progress then. We'll start with you, Saresha. Throw your best punch without the power of your energy cultivation."
"Y-you want Saresha to throw a punch at you, my lord?" Saresha asked for confirmation with a startled look.
"Don't make me repeat myself," Leon calmly stated.
"Y-yes, my lord!" Saresha replied before giving out a warning as she threw her punch, "Please pardon my offense!"
Bam!
Her small white fist landed squarely in the palm of Leon's hand without him budging the slightest inch; he stood his ground firmly like a mountain.
"About 38-thousand jin, huh? Not far from Rank 4 Body Tempering according to the primordial body cultivation standard," Leon analyzed with a casual expression.
Shortly after, Leon nodded before saying, "Now throw me another punch, powered by your energy cultivation."
"Y-yes, my lord!"
Saresha took a deep breath before she gathered power into her fist and exploded forth with a quick punch covered in darkness.
Bam!
The fist landed squarely into Leon's palm once again, and the dark aura dispersed like the ripples created from a rock dropped into still water.
Leon's hair fluttered from the rush of air, but he remained unbudged from the attack.
"About 500-thousand jin when the strength of body and energy are combined, huh?" Leon calmly analyzed Saresha's punch strength.
It was still far from the level of strength needed to move him.
"Alright, you can step back," Leon said to Saresha before calling for the next dark fae, "Who wants to test their strength next? Decide quickly."
"I will, my lord!" said a dark fae with short black hair.
Sometime later, Leon finished measuring the strength of every dark fae under him; all were roughly between Rank 3 to Rank 4 Body Tempering.
As for their energy cultivation, it ranged from Low to Mid-rank Lesser Demon level.
Although Saresha was the first to submit to Leon, her strength wasn't the strongest among the 50 dark faes.
Nevertheless, her strength still placed her in the group's upper circle.
"You didn't run into any of our clansmen during your hunt, my lord?" Saresha inquired after glancing down at the Lesser Demon-level demon cores Leon brought.
Leon shook his head.
"Did you think I killed them or something? No, it seems like the rest of your clansmen can only be found in the other sides of the Bone Sea's outer rim."
"Alright, that's that. We will meet them when we meet them," Leon stated before urging the dark faes, "Get back in the pool and continue to cultivate. I will restore its effectiveness."
Leon took out more Golden Ointment and All-purpose Healing Pills and mixed them with the bathwater, and before long, the medicinal bath exuded a strong medicinal scent once more.
The dark faes hopped back into the medicinal bath; some did it eagerly, while others did it reluctantly.
Nevertheless, the dark faes settled inside the medicinal bath and resumed their body cultivation while Leon estimated it was time to head back into the Abyssal Wood Forest.
'I've been gone nearly a day. I should head back and check on the others. Aria and Darlene might start to worry if I'm away for any longer,' Leon mused.
After making sure that the dark faes would be fine on their own for a short while, Leon departed the area with a burst of speed.
However, as Leon rushed back to Aria's location, he suddenly sensed a change in the sky.
Black clouds gathered around the Abyssal Wood Forest, forming an enormous black storm before deforming as if space was distorting.
Unlike any other phenomenon that forms a spiral tempest of clouds, the deforming black clouds above the Abyssal Wood Forest transformed into an enormous sphere of black clouds.
'A spatial storm? No, a spatial phenomenon! This must be Darlene's Transcendent Phenomenon!'
Leon's eyes lit up.
In the next instance, Leon kicked the ground and burst forward with greater speed as he rushed back at his quickest speed.
Without a doubt, the spatial phenomenon would attract a lot of attention to the Abyssal Wood Forest.
He had to be there to prevent others from interfering with Darlene's Transcendence.
