After hearing that, Karlos was angry as well as frightened. He didn't want to lose his brother, especially now that he had accepted his criminal identity. He even wanted to make his brother join the same organization as him so that he could help him get stronger and get the same benefits as him.
'If only he hadn't taken William hostage! I would have killed him already!'
Karlos gritted his teeth in frustration.
Luis smirked. 'As I expected. He doesn't dare attack me, but this also ruins the fun.'
"I'll give you a chance. If you can defeat me. I'll let your brother go."
"Are you serious?" Karlos asked with a deep expression.
'Of course not.' Luis chuckled inwardly but still answered with sincerity. "Yes, I never go back on my words."
"That's what you said." Karlos clenched his fists and a maniacal grin appeared on his face. "Don't regret it later."
As soon as he said that, his body disappeared from his spot, leaving an afterimage as he dashed towards Luis at an insane speed.
The speed of a B-rank was indeed too much for Luis, a D-rank. It was only because of his 'Perception' skill that he could see Karlos. However, his body can't follow those movements with his current rank.
Although Luis' agility was low compared to Karlos, he didn't even have a movement technique. He had something way better than all that.
'Spatial Jump!'
Once again, Luis dodged Karlos' attack, appearing a few meters behind him, and responding to him with a shot of Thunder Javelin at his ass.
"Ah!"
Of course, there wasn't much damage, but it did a good job of pissing off Karlos.
"What kind of skill is that?!"
Karlos still hadn't been able to guess that it was a space-element magic spell. After that guess was too illogical and horrifying, as per his common sense. So, he concluded that it was an S-rank skill.
He felt envious, and now he had another reason to kill Luis.
He took out a claw-like weapon and attacked him wearing that.
'Lightning Spear!'
Luis knew his physical strength was worse than Karlos. Hence, upfront confrontation would only keep him at a disadvantage.
So, Luis kept using his Spatial jump in succession to keep up with Karlos' speed and to do continuous attacks on him.
*Swish* *Swish* *Swish* *Swish*
His figure kept appearing and disappearing, besides because of his 'Enhanced Instinct', Luis was able to dodge all his attacks. Which caused Karlos to get extremely annoyed and frustrated.
'How is he able to predict my attacks?'
"Stop running, you coward! If you have the guts, then face me like a man!" Karlos hoped that with his provocation. Luis might get tricked.
However, only a light laughter sounded in his ears, which brought him chills.
"Hehe~ Don't bother with those silly tricks or else I might not play with you and directly kill your little brother."
As he said that, Luis also sent a fury of attacks. Along with his Lightning Spear, Luis also attacked him with Thunder Javelins and Thunder Bullets.
{Lily, scan him.}
{Master, his heart rate has almost doubled, and his blood pressure is way too high even compared to a normal harpy. This transformation will put his body under substantial burden. If he keeps this transformation for long, he will die.}
Luis didn't care about his life and death, but there was a greedy glint in his eyes. {A normal bloodline ability shouldn't have such effects, right?}
{Yes, Master. As you guessed, his bloodline transformation is unauthentic.}
When he heard her statement confirming his guess, a wide smile appeared on Luis. 'Hahaha, what a windfall gain!'
'I came here to save Bonnie, but who would have expected that I would see a pseudo bloodline awakener here? No matter what, I must catch him.'
"Are you scared?" Karlos' creepy voice sounded as he flapped his wings to stay airborne. With a swift gesture, he harnessed the surrounding air, gathering it into a swirling vortex of energy.
"This is something you brought upon yourself! Now no one can save you!"
In a seamless motion, he released the pent-up force, unleashing a powerful blast of wind towards Luis.
"Wind Blast!"
Upon facing the gust of wind blast surging towards him with incredible speed, Luis seemed calm. Even if his 'Enhanced Instinct' warned him of the danger coming from that attack. He remained unfazed.
Just when the attack was about to reach him. Luis conjured up a portal, swallowing the Wind Blast.
"Huh...? What!"
Karlos was stunned, feeling incomprehensible by this sudden change.
"What did you do?!" He questioned.
But Luis didn't answer him. Which made him further angry.
"Good! Since you won't tell me, let's see how you deal with a dozen 'Wind Blasts'!"
The next moment, a dozen white orbs appeared, floating around Karlos. Which, after a flap of his wings, shot at Luis like air cannons.
Luis was calm as ever, as he conjured around a dozen portals swallowing all the 'Wind Blasts'.
"What the..."
Karlos became shocked. Then he uttered in doubt.
"That can't be a skill... Is that some kind of secret technique? But no... your element is 'Lightning', right?"
"No way, could it be..." He realized something and his eyes widened in disbelief.
"Now I get it! Lightning isn't your element!"
He raised his voice, and in a confident tone, he pointed at Luis.
"What you have is a mutated element that also has the power of 'Lightning'! Isn't that, right?" Karlos didn't know what exactly Luis' element was, but it didn't stop him from feeling smug for some reason.
"..."
Luis stared at Karlos in silence. Then, a moment later, he clapped his hands and said in a plain tone.
*Clap! **Clap! **Clap! *
"Wow, you found my secret... Unfortunately, there's no prize."
