Chapter 558: Ultrasonic Assassin

After a nap, Kai woke up with a fresh mind. He saw Arba sitting next to him while watching their surroundings.

"Mhm?" Kai yawned while stretching his body. It was a short nap, but it was certainly satisfying. "Sorry for making you wait, Arba."

"It's fine. I know that I pushed you too hard." Arba shook her head. "Besides, it's all good now. You have recovered your stamina and we are ready to start the next training."

"Indeed." Kai nodded in agreement.

"Though, your student sent you a message right after you fell asleep."

"Really?" Kai tilted his head innocently while finding a message from Felice. He opened it without hesitation, wondering what Felice had to say.

"Big Brother, do you remember the day you told me all your magic? I'm sure you remember. I am sending you this message to fulfill the second requirement to be your student and wish to learn something about this so-called magic further."

Seeing the first paragraph alone made him shake his head helplessly. "Such a dedication."

Of course, he was happy that Felice did all this and praised her instead of getting angry. But it didn't change the fact that the test was only a challenge to rile up Felice, not something he made to strengthen himself or something.

Even so, he continued reading her message.

"Actually, I have been thinking about it for a while, but I want to specifically mention one magic that you never used."

"!!!" Kai widened his eyes when he saw this statement. The magic he never used, he wondered if that existed. Then, he figured out which magic she mentioned.

It was none other than his Ultrasonic Assassin. The magic released an earth-shattering sound and a powerful shock wave like that of a nuclear bomb. Due to the limitations of the simulation world, he couldn't utilize it to its fullest potential, but if he used that magic, he would have become a walking nuclear missile.

The sound wave that carried more than 200 decibel sound certainly had enough power to turn a region into a wasteland, depending on how much he poured his magic.

However, it also meant his body would perish alongside this magic. After all, there was no way his body could withstand a nuclear missile.

This realization alone piqued his interest, wondering what kind of aspect Felice saw from this impossible to use power.

"I am thinking of building a certain barrel that can withstand your power. Of course, you need to lower the power of this magic unless you want to kill yourself. I believe you can do it since you have done it a few times with other magic."

Kai furrowed his eyebrows and remembered how he gradually changed the characteristics of the sound. He certainly had the ability to do it since a long time ago.

He wondered what was inside Felice's head to the point she managed to realize all this. With his heart pumping in anticipation, he proceeded to read the next part.

"This barrel will allow you to send a Sound Wave in a certain direction, allowing you to shoot a powerful bullet which carries only your power. Unfortunately, I can't do much about it because of my lack of ability to control the direction of the magic.

"If I can control the direction, I'm planning to spread my power a bit… Like a fan-shaped area. This will disperse the power enough and create a powerful sound wave that can destroy everything on its way. Of course, it will depend on the restriction you put in your Ultrasonic Assassin magic.

"This is very dangerous magic and I can certainly classify it as a double-edged sword even if you can control it. One wrong misstep will lead to a big disaster… Well, I'm sure Big Brother knows this better than me. But yeah, this is what I have learned here."

Kai facepalmed and shook his head helplessly. "This girl… She is so brilliant."

In his mind, he started visualizing the magic she thought for him. This magic might become the base magic of him, who became a new protector.

After all, he remembered Ishii using his power to crush the enemy like nothing. He also had seen his friend, the dolphin, erasing one's memory with just a single wave of its head.

If he could control his Ultrasonic Assassin to a certain degree, he would become a walking nuclear. In this case, he might be able to fight against Neptune.

His heart was pumped with excitement as he finally saw the path to survive.

With this message in mind, Kai looked at Arba. "Say, I think I have seen my path. The path that can protect humanity from other races."

Arba widened her eyes and stared at him with a shocked expression. "Ehm, congratulations? I don't know this path, but if you think this is enough, this path should be strong enough to contend with that bastard, Neptune."

"Ahaha, I don't know, but it may be." Kai nodded. Although he was a bit hesitant, he knew that this might be the best shot he had against him.

"Still, even with Mystic, I don't have enough power to contain its full potential. I mean, the direction alone is a hard thing to control, then there is the power…" Kai let out a long sigh.

Seeing the potential of this path, Arba bent her knees. "I, Arba, am ready to lay down my life. This is the fight we can't afford to lose, so even if this path you seek requires my life, I won't hesitate to give it to you, my king."

Kai smiled but still shook his head. "I am not a good person, but it doesn't mean I will sacrifice my people unnecessarily. As you already know, I always tried to decrease our casualties."

"By going to the frontline yourself," Arba added in agreement.

"Y-yeah." Kai chuckled. "I am blessed with so many people, including my disciple."

Arba shrugged while smiling.

"Anyway, what is the next training? I am ready right now." Kai smiled. With him finding his own path and goal, everything seemed to be a challenge for him instead of a hurdle he needed to cross because he had no choice.

He became a bit more energetic as he looked at Arba, saying, "Let's go."

"Actually, you are going to swim in the longest river in India while putting on some ridiculous weight. The time is going to be short too and you may need to fight the current."

"Is that why we are here in Delhi?" Kai's eyebrows twitched.

"Yes. It's not that far anymore, so we can get there today and start your next training. I mean, at the very least, you will need to experience the training on land, in the water, and the sky."

"In the sky?" Kai made a weird expression and shook his head helplessly. "I feel like I have been dragged to something ridiculous."

"It's necessary." Arba shrugged. "I had undergone such training too when I was chosen as the priestess. Leah had completed it too."

"Though, it's not as extreme as mine…" Kai rolled his eyes.

"Ehm, yes." Arba looked away, feeling embarrassed. "Great power comes great responsibility. Your status is greater, so is your training."

"It doesn't work that way." Kai facepalmed and resigned to his fate. "Okay, we should go right now."
