Eldia looked at the strand of an arc of lightning that shot out of her master's abdomen. It was covered in a pure white light that made her feel a bit comfortable when her sense probed it, but her attention wasn't at that marvel but the heavenly lightning. Even though it was just a tiny strand, it held an immense amount of pure lightning energy that she felt like she would be more than full after devouring it.

Davis extended his soul sense and confirmed that there were no threatening magical beasts around in this part of the Dark Thunder Island. Only the black-lightning that fell irregularly could be seen. Even if some magical beast came, Nadia's doppelganger could easily take care of them. Therefore, feeling like he could concentrate on Eldia's consumption of the heavenly lightning strand, he took a deep breath and spoke.

"Eldia, I'm giving this invaluable treasure to you, so make sure you fully digest the benefits it would bestow you."

"Yes, Master..."

Eldia began to form her lightning energy body to make her offense and defense stronger. Her womanly figure quickly became covered with black-lightning as it began to crackle with intensity.

Davis dispersed the life energy from the strand of heavenly lightning. The heavenly lightning crackled a bit, but it did not turn berserk. It stayed like that for a few seconds, floating in mid-air.

*Rumble!~*

The clouds above began to actually change shape.

Davis looked above and saw that the ever-present dark clouds were converging.

"Heavenly tribulation again...?"

His eyes narrowed as he gasped, but then it began to rain as thunder began to rumble.

Davis's heart that had just begun to pound calmed down.

It was just a change in weather.

"Eldia, devour it..."

As if waiting for those words all this time, Eldia rushed and took the heavenly strand of lightning into her globular body that crackled with powerful black lightning. It was like a giant maw that swallowed a sizeable portion of food.

*Bzzz!~~~*

Lightning began to furiously crackle, even spreading to the surroundings!

Davis retreated a bit at the intensity. His eyes narrowed as he focused his gaze on Eldia while it became clear to him that she had begun the refinement process, but he had no idea how the result would be.

A few seconds passed, and by now, he could see that she was fairly holding up, not like him where his fleshly hand was quickly burned up, almost turned into ashes if he had allowed more energy to invade.

"Davis, is this fine? This elemental would get stronger and might be able to break free from your grasp..."

Nadia abruptly spoke beside him, her melodious voice echoing in his ears. He turned to look at her, smiling with a shrug.

"Then she's simply courting death. I've already said many times to submit to me, so if she doesn't, I'll be simply erasing her Will."

"I see..." Nadia nodded her head, her beautiful face producing an eager smile, "However, I do want to see how strong she would become after devouring this heavenly lightning. Would she become powerful than me, a King-Tier Magical Beast?"

"That remains to be seen..." Davis smirked along with her.

At this moment, Eldia was at the Peak-Level Eighth Stage. If her prowess were to be graded, she's a Mid-Level Emperor Grade Lightning Elemental who has reached the very apex. She had already lived for a long time, so it would not be strange if she is able to experience a breakthrough to the Ninth Stage. However, she was suppressed for so long by the Silverwinds that the energy she might've accumulated in all these years was never obtained in the first place.

If she had not gone back to the Dark Thunder Island, her natural environment, to regain her energy, and if Davis had not provided the energy she required, she would be in a malnourished state. Fortunately, it seemed that the energy that she collected here was enough for her to enrich not only herself but also almost reach the very peak of the Peak-Level Eighth Stage.

She was somewhere around breaking through, but he didn't know how soon.

Moreover, although this strand may be tiny yet immense, it was only the residue left, actually leftovers from the heavenly tribulation. The energy the strand contained was of immense value only because of the purity, not because of the amount of energy in it because it wouldn't even match ten percent of his soul force capacity, but its destructive prowess was such that it could very well make him spend more than fifty percent soul force if he wasn't using the death energy or life energy.

In any case, Davis was convinced that he almost made the right choice in believing Eldia. Now, all that remains is for her not to turn hostile after she devoured the heavenly lightning, but Davis was sure that the chances were abysmal. He was already more than convinced that she would not betray after the confrontation. He believed his judgments and choices never failed him, at least for the most part, according to his experience.

"..."

Time passed.

"Master... I'm finding it difficult to refine this strand..."

Eldia's voice suddenly echoed out after a few minutes.

Davis nodded his head, feeling that it was as he expected. It took more energy to refine that heavenly lightning strand that he could see that Eldia was running out of her lightning energy. It was rather obvious as he could see that her globular black-lightning body was already dwindling as the lightning that crackled around her became fewer by the second.

Moreover, not only was she refining the heavenly lightning, but she was also absorbing it, fusing the refined energy of the strand with her Will. Thus, it took her more energy to absorb the benefits rather than simply refine and accumulate energy.

Davis raised his hands and sent his soul force towards her. His soul force tinged with a light red color of the Incandescent Vermilion Soul Mantra quickly began to crackle with black-lightning. His soul that was tempered by many Lightning Elementals, made it possible for him to use lightning without injuring his own soul in the process.

The black-lightning quickly made its way into Eldia while she began to absorb it. But, unfortunately, the surrounding lightning-attributed energy was also sucked in by her, almost creating a void of empty energy if it weren't for Davis supplying her with his lightning attributed energy.

Quickly, Eldia's black-lightning began to visibly brighten as it extended to the surroundings! Finally, she was back in shape, absorbing Davis's soul force to her heart's content while blending with the stubborn strand of heavenly lightning.

"Thank you, Master! I won't disappoint you...!"

She echoed, seemingly becoming energetic again.

'Oh... She cares about not disappointing me...?'

Davis blinked, finding Eldia more and more human. If only she had a human body like Nadia and most magical beasts, he could look at her with a more humane perspective. Unfortunately, it was just difficult for him to truly sympathize with energy beings even if he tried, but he was already starting to find her endearing when hearing her feminine voice.

She had been more articulate than any Lightning Elemental he had ever seen, or even any Spirit Attribute Sources for that matter.

Davis inwardly nodded to keep her and grow along with her if she didn't betray him. He provided her with energy and watched her absorb the heavenly lightning as he waited.

*Bzzz!~~~*

Davis saw the black-lightning escaping from her body, releasing a terrific might. He instantly retreated a few more steps while Nadia stood in front of him, simply waving her hand as she used a darkness veil to stop the crackling black lightning from hitting them.

Nevertheless, the dark veil could still be seen through from both sides.

Abruptly, a massive change began to occur in Eldia.

Her globular body of black-lightning shattered, revealing her naked self. Of course, it wasn't like she was naked, but her black-lightning covered body was revealed, flashes of strange and foreign blue lightning arcs radiating like veins in her tiny body.

It could be seen that a change was occurring in her Will.

"What's it gonna be...?"

Davis excitedly uttered as he looked at Eldia.

The atmosphere became abnormally silent instead of the constant crackles of the black-lightning. None were present, and Davis had already stopped proving her his energy. He looked intently, observing the changes to get some inspiration.

However, when he thought that he was looking at a naked black-lightning silhouette of a humanoid woman, his expression turned awkward, and he was no longer able to concentrate. Before he could become focused, the heaven and earth energy abruptly began to form around them like a tide!

No, it was forming around Eldia!

*Bzzz!~*

Black-lightning began to crackle again as it now surrounded a radius of half a kilometer. Davis and Nadia were engulfed in it in an instant when Nadia reached out both her hands, strengthening her veil the same instant as she defended against the random bursts of attack.

The black-lightning receded almost as soon as it came when a voice suddenly echoed.

"I'm sorry, master... I wasn't able to control the sudden burst of my growth..."

Eldia apologetically echoed, but Davis looked as if he hadn't bothered about it.

Instead, his eyes flashed with a peculiar light as he sensed the prowess of Eldia's black-lightning.

"A Peak-Level Eighth Stage Lightning Elemental that could transcend two levels... Or, in this case, just a single level due to a stage separating the gap..."

His voice echoed out, causing Nadia to smile, a bit provoked as she moved her lips.

"Just like me as we expected..."

Davis nodded, feeling pleased... overly pleased that he now had an additional Ninth Stage Powerhouse with him!
