"You have come." Tasha smiled and said after noticing his presence.

"Uhm, yes." Kai nodded.

"How is the situation?"

Kai pondered for a moment and said, "Firstly, it will be about the number of enemies of our respective army. The right has three thousand, we have six thousand, the reserve has five thousand, and the left has six thousand.

"I don't know why, but the reserve army is rolling right now. They are killing at a rate far faster than any of us. Though I feel the general is pushing it too far. In any case, we are in the stalemate with our enemy right now."

He told her because he wanted to reorganize his thoughts by saying it out loud.

"It's good then. Although our situation is still unfavorable, we can win this." Tasha nodded and fell into silence. She glanced at Kai a few times while shooting her lightning arrows. "Kai, you are hiding something, aren't you?"

Kai didn't answer as he only stared at her for a few seconds.

"It's fine if you can't say it. Just your reaction alone is enough for me to know you have been hiding something and that something is a big secret." Tasha shrugged, drawing her bow again.

"Sorry, Sister. Even though you and Michelle are the two people I trust the most, I can't say anything about this." Kai said while closing his eyes, picturing several reasons.

"It's alright. I shouldn't ask about it anyway." Tasha smiled before changing the topic. "Anyway, what are you going to do with our current condition, and what do you want to achieve by coming here?"

"I won't do anything about our current condition yet. As for what I want to achieve, it's simple. I want to master my new magic because only by experimenting in this kind of battlefield, I would get a better result." Kai smiled.

"Your new magic? Ah, we forgot to discuss it back in the Lion Group Room."

"I just want to find the right frequency of sea creatures and destroy them from inside if possible." Kai smiled.

"Oh, right. Just like shattering a glass with sound at a certain frequency."

"Yeah. Though I need to search for every magical beast frequency since just like crab and turtle, they have their own frequency."

"That magic is going to make you a wanted person, you know. After all, you are like the last boss where you can kill someone by shattering their heart with frequency." Tasha smirked.

Kai shook his head and sighed. "It's not something that omnipotent. Just say a person's eyeballs, I can only destroy their eyeballs after more than ten seconds. At that time, if they wear glasses, the time needed will increase. And if they have another preventing measure like a plate or something, almost no sound wave would come around them unless I use high energy but low frequency. Unfortunately, it would take too much magic and not worth it since I can just send their head flying with my sword."

"True enough. They might even change places if they are getting some symptoms. If it's a magical beast, they would most likely charge at you. As long as you keep your distance, you can bring them down." Tasha smiled, giving her opinion about the magic.

"That's basically my plan."

"Though I really wish you would have the Vibration Sword. After all, it will increase the sword sharpness extremely and might even cut steel like cutting tofu."

"It's just a concept. I have altered the magic, and we only need to get the new swords to test the power." Kai shrugged.

"What if that person wants you to visit her?"

"Ehm…" Kai glanced left and right, not knowing what to say. He ended up ignoring the question as he raised his hand, pointing it on a magical beast.

She stopped talking and smiled, continuing her job. Besides her, Kai created a green magic circle.

The process of this was extremely tedious. Kai could only check whether the frequency was right after three seconds as the magical beasts would react to it. In other words, if he targeted one magical beast, he could only test twenty different frequencies in one minute or one hundred. And he also needed to control the intensity of the sound.

It would require months to test all of it, so he could only test in a brief period and noticed the difference with his ears.

He raised his left hand and created another magic circle. This magic circle was his Sound Insulation Room, while its purpose in this experiment was to prevent the sound from distracting the people around. Although it wouldn't trap the sound completely, it should still be enough to reduce the noise to a significant degree. He needed to do this because, unlike the first time where he shot it to Isabelle, he would use the frequency that could be heard by human hearing.

Michelle also noticed Kai's presence on the battlefield. She just took a glimpse of his condition and continued killing the magical beasts.

With Kai observing this battlefield, there should be nothing wrong unless there was an unexpected threat that was hard to discern with hearing alone.

The battle continued for three hours without much progress. From his point of view, they had killed around seven thousand magical beasts in total while having almost five hundred casualties. It could be said that this progress was one of the best scenarios they had, but this also made Kai suspicious.

If the other party had intelligence at the same level as a human, they should notice it too and act accordingly. He didn't know why, but there was an uneasy feeling shaking his heart this whole time.

The battle continued for another hour, and the intense feeling finally reached its peak as he suddenly heard another voice from the sea.

"Skrat Kri."

"Qui!"

Kai heard them talking again, making him furrow his eyebrows. He was wondering what kind of plan they would use again as he muttered to himself. 'Is this the intense feeling I got the entire time? What are they planning to even make this feeling? The animal instinct usually warns me about danger, so this must be something dangerous…'

The voices continued like having a conversation. Just like last time, he tried to discern the message by the tone alone, and he felt they were having a conversation about their plan.

After around a minute, the dolphin's voice suddenly intensified, and the real battle finally started.

"Roar Roar Roar!"

A series of roar echoed through the battlefield. Not only in this battlefield, but also on every battlefield. Kai didn't understand their language, so he focused on hearing and trying to see any change.

It was at this time, Tasha's expression turned serious. "Kai, be careful."

Tasha made a purple magic circle on her hand, pointing it to the front. In terms of sight, Tasha was better than him. In this chaotic battlefield, even Kai might not be capable of discerning if someone targeted him unless they released their attack. However, the moment she said that the animal instinct inside him was tingling, noticing an incoming attack.

The green magic circle on his hand vanished as he took both of his swords, searching for someone that made this sensation.

On the other hand, Tasha made a lightning spear but had yet to release it.

"Here it comes!" By investigating the battlefield after Tasha's warning, Kai finally spotted one magical beast that was doing something irregular.

"Electric Lance!" Tasha finally released her magic as she saw a blue light coming toward their place.

The lance and the blue light clashed, creating a shockwave that shook the entire battlefield.

Jack made an unpleasant expression and shouted, "What the heck is that? Oi oi, don't tell me there is an A class magical beast here? And seeing how it's attacking us in this timing�� This one should have unlocked not only its magic but also its intelligence."

"Target on sight! An intelligence A class magical beast is spotted in my area." Jack quickly informed the others.

"Is this really the only thing I feel?" Kai furrowed his eyebrows, concentrating all his attention to his ears before noticing that the others also experienced the same thing.

In the right army,

Marsha leaped to the air, avoiding a crab strike from its sharp claw. Surprisingly, the crab pierced the ground, creating a hole enough for many people inside.

Marsha swung her glaive before the hard claw blocked it. "This is certainly going to be troublesome…"

Just like her, the left and reserve army also had their respective opponent. However, Kai noticed something that no one would ever notice.

"This is not good. I need to go to the left army!"

"Kai? What happens?"

"Sister, teleport me to the left army." Kai grabbed her sister before releasing an oscillation shield to block another blue light.

"Boom!"

"The left army is in danger right now!" Kai's voice startled everyone. "I don't have enough time to explain, but we need to reinforce the left army."

"What is this all about, Kai Carter?" Sanders frowned as he might not have some leeway to reinforce the left army with their current condition.

"General, there are many things to explain, but if we don't reinforce the left army, this battle will be as good as lose!"

"Kid, are you underestimating me?" Sarah couldn't take it any longer and said coldly.

"If you think you can fight another two thousand flying beasts and one intelligence A rank beast, then feel free to say I am underestimating you!" Kai roared to the radio.

*Thud*
