HISSSS!
Fey gasped, her eyebrows twitched, as she learned just how special her causal ability was... 'Even my brother has only one mythical grade ability. It looks like I'm really lucky.' she paused for a moment as this thought passed through her head.
"But I feel that I can only use 'Phasing Punch' twice after I've used it just now," Fey said.
Fein smiled and said. "All abilities had restrictions. And the stronger the ability, the stronger the limitations. Causal Abilities can defy logic and they are absolute most of the time, but because of this, it has the limitation of the number of use. My mythical ability may not be as powerful as yours, but it's more versatile and useful."
Fey's pupils lit up, and she nodded her head in enlightenment. "So that's how it is..."
Her brother had explained the matter to her, and the more knows, the more she found it reasonable.
Fein turned his back to his sister and put his hands behind his back like a mysterious expert who had experienced the up and downs of life.
"But there's always an exception." He paused and said. "That's why there's a god-level ability. They are powerful and have less restriction than causal abilities!"
"God-level abilities." Fey muttered the name of the highest grade in his brother's classification with longing and asked, "How do god-level abilities works?"
"Ahmm... Honestly, I'm not familiar with them." Fein scratched his head awkwardly. "I just guess that god-abilities might have already involved the power of time, space, and creation, just like causal abilities. the difference between the two was, the god-level abilities are less restrictive and stable than causal ones..."
"I didn't see your mythical grade ability. Can I see it?" Fey stared at her brother with eager eyes.
Fein turned around and nodded. "Use your Super Speed this time and your Phasing Arrow."
'Super Speed!' Fey activated the ability that she used once when the hunter chased her. Suddenly, she could feel her body become lighter, and the motions in the surrounding became a lot slower. 'So this is Super Speed.'
Fey scanned the surroundings, the leaves of the trees sway slower, and the drifting clouds in the sky became still. The sounds became eeriely quiet in her perception. She knew that it would take a while before she gets used to the 'Super Speed' state.
'What if I combine the speed the repulsive forced provided while I'm in this state?' Fey could feel her heart thump with excitement.
Fein, on the other hand, had already entered his 'Chess Perception'. As he knew that the next time won't end as easily as before.
DING!
[Super Speed- Enhanced the user's speed by twenty-five times!]
Just like that, Fey immersed herself in her 'Intangible' state and phased through the ground like before to boost her speed. After she get bounced back and forth on different kinds of surfaces fifty times, she could feel her speed had reached the limit.
'Damn, she had reached mach one hundred!' Fein watched Fey gradually turn blurry in his vision, even in his 'Chess Perception' he could just vaguely perceive her existence. If not for the heat created from the friction that produces sparks on her way, Fein would have already lost her.
'Probe!'
Name: Fey
Race: Human
Degu Amount: C
Str: C+
Agi: B
End: C+
'The system didn't include the speed bonus of the repulsion. And her super speed had increased her C+ to B class.'
'It seems I needed to release to release the suppression in my body.' Fein felt rather proud of his sister because he managed to push him to use at least fifty-five percent of his combat prowess.
Fein took a deep breath as he released the suppression in himself. Just like that, his reaction speed and visual acuity returned to the peak of A-rank. As his agility, strength, and endurance returned to their peak.
When he looked at his sister again, her speed had turned normal in his perception even at the fact that Fey is literally a hundred times faster than the speed of sound.
'The difference between the realms in the upper ranks to the lower ranks is comparable to the sun and moon.' Fein sighed with emotion.
'Let's recover our lost face earlier.' a smirk appeared on his face.
Although it looked like that, he didn't mind that her sister landed a hit on him. Truthfully, he felt that he lost his majesty as the older brother. And he knew that he needed to take it back. And with his spar, he has a theory of his that he wants to confirm.
'It's time!' a strong repulsive force catapulted Fey. She manages to perfectly change her body's trajectory in her brother's direction.
Like a speeding bullet, she arrived right in front of her brother with all the accumulated momentum she had and raised her fist, intending to punch his Fein in the gut.
"Too slow." Fein stood with a straight back like a god of war as he watched his sister's incoming fist. He opened his arms and lifted them closer to grab Fey's jab. But just like what happened earlier, his arms just glitched at her sister's arm.
'Tch...' Fein clicked his tongue at his sister's troublesome ability. "Did you really think that the same trick would work on me?" his eyes darted at his sister's fist that materialized in front of his face. With his current A+ rank speed, he could dodge this with ease. But he decided to use his 'Ghecko substitution' at her sister's request.
Just like that, Fein disappeared in his place, a huge boulder had replaced him. Fey stared at the boulder with astonishment. And her fist landed on it.
BOOM!
Due to her speed, she became powerful enough to explode the boulder into dust! Speed creates power, and this scene perfectly showed this.
Suddenly, she felt a gaze on her back. When turned her head, she saw her brother smiling at her in the distance.
'So that is the mythical grade Ghecko Substitution?' Fey pondered at her brother's amazing ability. 'It seems I need to step up my game, Phasing Arrow!'
