Killua with no affiliation from a known family was a famous yet mysterious immortal in the Cloud Continent. Not just because of his pure talents in swords, but also for the fact that he only use martial technique instead of mystical arts despite being an immortal.
Martial Techniques are becoming less formed in Immortal Heaven. As Mystical Arts were becoming more popular to others, it just had a simpler and more powerful impact on the enemies.
Here in Immortal Heaven, having no talent in mystical arts or just martial arts means you are weak. As the difference between the two is vast, immortals tend to judge those who only use martial techniques that have less mystical power.
When a mystical art form is used, an unexplainable phenomenon can occur. A mystical art attack could be otherworldly and unique in its method of killing someone.
They could create fire from using Qi, but martial techniques can only make an image but not actually create them. Those two are different as martial technique is the effect, while the mystical art is phenomenal.
"Master of the Northern Blue Blade, do you still use that name?" Senior Hui asked while they were making their way to the pavilion where Felicity stays.
"Yes, Senior. I still use it. Not at all times, however."
"What do you mean by that?" Senior Hui asked, as his curiosity was piqued.
"That nickname is a complicated matter between the stereotype of martial techniques and mystical arts. As immortals only use formless mystical arts, I tend to try to forget those memories."
Senior Hui just didn't ask furthermore. He knew that it was a heavy topic for Killua and he didn't pursue to disrupt the reunion they had. He was just happy at this time, and he can't destroy it since he treats Killua as his brother.
"What was the Madam doing anyway? Did she just come back abruptly?" Killua asked.
Senior Hui just snickered after a sigh.
"Yep. I was taken aback yesterday when she suddenly appeared in front of the gates of the pavilion. And I recognized her from her title, "The Immortal Fairy of Unending Falls"."
Killua was just silent while Senior Hui was telling him the story. And, just as he was taken aback by Felicity's sudden return, he couldn't help but wonder what had happened.
'Did the Madam come back for her master? Saying that a respectable master was in Mortal Heaven, does that mean Madam came from the lower heaven?' Killua pondered.
But Killua knew that even if he wondered about it, he still wouldn't get an answer. And so, he kept his question to himself and saved it for later.
And just a few minutes later, Killua and Senior Hui arrived at the pavilion where Felicity was.
'Am I ready to meet her again? I am worried about how she'll react when she discovers that I didn't help my family after she left.'
The doors of the pavilion slid open, revealing the interior, where Felicity was sitting at the other end of the room.
There was a sliding painting at Felicity's back of some kind of scenery that could be only found on another continent, and as Killua saw it, he gulped in nervousness since he knew what that painting meant.
The painting was actually only of a beach with white sands. But even with how beautiful it is, it holds a great history. The same painting was painted by an artisan that came from Killua's previous family. Killua's previous family, on the other hand, were bloodthirsty murderer immortals.
Not just normal murderers that kill, but disrupters of public order placed by the ambassador of Immortal Heaven. And with them being hated by the public, their paintings were deemed death threats to other people.
"You're back, Killua. What's with the pale face?" Felicity blankly mumbled in slight audible tone.
Killua nervously faced Felicity but was still bothered by the painting; his knees unintentionally surrendered.
"I greet the Madam," he uttered like a powerless dog in front of its owner.
"It's okay. But why are you so tensed. Did you do something? I heard that you did well in your training."
Killua slowly raised his head and asked, "Were you having eyes on me again, Madam?"
Felicity didn't reply, instead, she only gave him a mysterious smile, making him more anxious of what will going to happen.
"Killua, you were a great child. What was your age again, 1400? You're still an adult as an immortal, but with how you act, it seems like you see the legacy as a joke."
Killua gulped once again. As Felicity was darting him with unknown gaze, Killua couldn't gather his thoughts to work properly.
"But Madam, I needed you."
Those were the words he said, and after realizing what it meant, he covered his mouth.
Felicity was surprised to hear it and couldn't help but show her reaction. Her eyes widened and froze at Killua's location.
"I-I... I understand. Please remove the paintings, Senior Hui." Felicity ordered, which Senior Hui followed immediately.
"Look at me, Killua." Felicity said. Killua immediately followed her command and looked at her with still worried eyes.
"I played the legacy as a joke, but right now, I am willing to continue it. Do you know why?" Then silence covered them for a few seconds, "Because I found a master."
Killua didn't respond at that moment. He just took things to sink in as he understood why Felicity was showing him some of his previous family's paintings.
He was still nervous, of course, but not to the point that he was expecting punishment. Just as Felicity was starting to lessen the tension in the atmosphere, Killua started to breathe easily.
"Killua, will you play a role again to complete my legacy?" Felicity said, majestically emitting an aura around her for Killua's eyes.
Killua's eyes, on the other hand, sparkled in admiration. He saw the image of Felicity when she was here in Immortal Heaven a thousand years ago. Just like that, he saw Felicity's benevolent self once more.
Killua's eyes teared up as he lowered his head and clasped his hands.
"I accept the responsibility, Madam. Please accept me, I will do my job again."
Felicity smiled as Killua pronounced those words. And as things continued, a light emerged from the ceiling of the roof. It was a symbol, a formation Felcity had created. As the formation started radiating more brillinat, Killua's body was covered with it as well.
Felicity on the other hand also shone brightly. The light as well covered her body, and after few seconds, they both felt refreshing and nostalgic embrace of energy.
"From this day, you will be my child again, Killua."
Killua couldn't find the words, so he just smiled as tears streamed down his cheeks like waterfalls.
When Felicity saw it, she snickered.
"What an idiotic face is that, Killua? You are not a kid anymore."
"I know, Madam."
***
A thousand years ago...
A boy with dark hair walks through the woody forest with bruises all over his body.
He was panting, as if escaping from someone who was chasing him earlier. It was endless for him. He dashed through pointed woods that even added fuel to his wounds.
Stings also filled his system, and his face was painted with pain, grumbling from it.
And as he continued running away from someone, his feet met, making him lose his balance and stumble.
Another wound appeared on his face as it hit the ground first. Now, all over his body, there was no visible space available for another wound, but for the boy, it wasn't even a thing to bother, he just need to escape.
But how could he escape if he was degraded to this state?
From a weakened heart, he couldn't help but tear up. His head slowly turned to face his back as there were brushing sounds that were slowly coming his way as well.
His face became worried, scared of what would happen to him at this moment. And as the brushing sounds disappeared, his eyes widened. A shadow appeared before him.
"You were too slippery for a kid. I praise the effort, but this will be the end of you, tainted blood. Starting with you, we will avenge our family," a man said with a hoarse voice.
The man who was chasing the boy had a scar across his left eye and was bald. It was intimidating for the boy, but not enough to scare him to death as what fears him was the weapon on the man's hands.
"I don't know any mystical arts that can erase you immediately. But do you know what I know? It's a martial technique that can torture your small body."
The boy doesn't have any energy to move. His spiritual energy was already drained by an array that earlier he stepped on. And as what he fears, this will be the end for him.
"You are scaring the kid."
Blood splattered after a mysterious female voice resounded. The blood reached the boy's face as he slowly sank into what had just happened before him.
Not anticipating it, the threat disappeared, but who was that person who killed the man, even detaching the head of the man from his body.
