Chapter 216: New Magic

"Ooh!" With the roars shook the battlefield, the soldiers were revitalized.

Kai kept causing a big stir to show that he was advancing with them.

Michelle realized his movement and immediately pulled back while sending another Shadow Slash to keep Eru from moving.

Ayaka and Sofia raised once again as they stared at the water elemental. "You won't pass us this time!"

Whether they had a plan or it was simply their pride, determination filled their eyes. And the battle started yet again.

Far in the sky, Nathan, standing inside the cockpit, could also see these people fighting in absolute disadvantage.

"General… They only have around four hundred people left. From our report, their number was almost eight hundred… but it seems most of them have fallen. However, we can't spot their general, Abec."

Nathan's face was distorted, not because of the dying soldiers. He was angry, looking at how the Protector controlled the situation. The report said that it was five thousand magical beasts. Their seven hundred or so soldiers should be enough to last for long, especially with Kai and his group. Yet, they were in the middle of collapsing, baffling him.

Nathan looked down, contemplating their battle strategy.

"Do you want to contact other planes, General?" The pilot glanced at him, ready to give a signal.

"Bryan will take five hundred people to reinforce the right army, while Albert will take another five hundred to help the left army. One thousand soldiers under my command will attack them from the front. I will take care of that monster over there." Nathan pointed his finger at Eru.

"Roger that." The pilot nodded. Although they couldn't use communication tools, their airplanes had been strengthened by some lighting. Right on the side of their cockpit, there was a big red-light bulb outside the plane. The same applied to the other side and the other places around the planes.

The pilot sent a Morse code to the other planes using this feature while the two spread the signal so the others could receive the order as well. This way, the magical beasts wouldn't pick up their communication signal and stay under the sea. This had become another reason why the government chose to produce more of these cargo airplanes because this technique was not practical for a high-speed air battle.

"There are only thirty seconds before we are ready to drop off. I am going then." After giving his order, Nathan said goodbye to the pilots and left the cockpit.

"Good luck. General!" The two pilots saluted until Nathan left.

Meanwhile, Kai also realized their plan due to his extraordinary hearing. Luckily, they were inside his hearing range due to the fact of how low they are flying. He took a deep breath and looked at Michelle. "Go help Ayaka and Sofia. I will handle him alone… Soon, your Grandfather will help me, so don't worry."

Michelle hesitated for a second before nodding her head and leaping toward the giant monster.

"Do you think you can stop me alone?" Eru glared at him.

"No. I just believe that you are going to lose in just a few minutes." Kai shook his head. He had realized the strength of the Protector, so he answered without hesitation.

Back then, Ra was trying to help Eric even though he had been living on the land for a long time. Compared to Eru, Ra seemed to only use thirty percent of his original power. That was why he knew that even Ria might probably lose if she fought against the Protector in a situation like this.

Eru gritted his teeth, couldn't stand to see this calmness. Even though Kai was already injured all over, he should be able to hold him down for a few minutes. And the fact that the situation on the battlefield didn't turn worse because Tasha sent many magical beasts to the sky, Eru knew that the situation would be overturned in a few minutes.

He took a deep breath and laughed. "Haha! Good good! I never thought that you could make me this desperate! You are indeed a man of talent, Kai Carter. Let us see whether you are still able to hold on after a few minutes because I will now fight with my life on the line!"

Kai would never expect this type of response from Eru. He gritted his teeth and roared. "Ha!"

The two leaped toward each other, clashing a few hundred rounds in just a matter of seconds. Kai was punched and injured all over his body, but Eru was no better. After ignoring his defense, Eru was going for the offensive, not caring about his wound even a little bit. As a result, Kai's wounds were far worse than his. Suddenly…

*Clang!*

"Kh!" Kai's sword was blown away by the claw as another claw was trying to punch him right on his stomach. "Oscillation Shield!"

The green magic circle appeared and stopped his claw.

Eru also felt the repelling force from this magic circle. Nonetheless, he realized the force was already too weak to stop his attack. Eru broke through the magic circle and punched him on the stomach, blowing him away to the magical beasts.

*Bam!*

"Thank you, Isabelle." Kai panted as he realized Isabelle shot her bullet at the last second to reduce the impact from the punch or else, he would get some broken ribs.

Neither Eru nor Isabelle could hear Kai's voice, and the former already charged at him.

Kai noticed this and remembered one last thing that his Teacher had entrusted to him and immediately cut some magical beasts into some big pieces, sending them flying to the air.

Tasha didn't know why but she felt Kai wanted to do something different before recalling what Ria Ross said.

"He already has the concept… But he lacks magic power. If the requirement is fulfilled…" These words flashed in her mind before she opened her mouth in surprise.

Kai created several magic circles around him, facing Eru. They were all behind the magical beasts' parts.

"To think I would use my magic before testing it first…" Kai muttered to himself before using his Sound Insulation magic to close his ears. "Anyway, I can only risk it if I want to win."

Eru furrowed his eyebrows, not knowing what kind of attacks Kai would show him.

"I haven't named it yet, but I will call this for the time being." Kai activated his magic circles as soon as the magical beasts aligned with his magic circles. "Sound Blast!"

The magic circles released a high frequency and energy sound, blowing the magical beast parts like throwing a rock. They all flew like a bullet, and their target was none other than Eru.

"What?" Eru was surprised and tried to deflect everything with his claws. There were still a few pieces left, with a whole giant crab flying toward him. He deflected it like the others, but Kai was actually using the crab as his cover.

"Do you like my present?" Kai smirked as he slashed Eru with his sword, creating a quite deep wound on his chest.

"Argh!" Eru spat out blood as he saw Kai already a few meters away from him.

"The magic is really taxing…"

Kai's condition was not any better. He was panting, trying to catch his breath. The new magic was indeed taking a toll on his body. The concept of the Sound Blast was taken from the Sound Levitation. However, he felt the force behind it was too weak.

He had tried many things to strengthen the force but to no avail. One month ago, he finally found a rough concept on how to fix all the flaws in Sound Levitation. First of all, the concept itself was something similar to his Oscillation Shield. Vibrating the particles and sending powerful energy through the air.

By using this concept as his lead, Kai went further with his research. He remembered he had something that could fix the power. Although it was a double-edged sword, it was only if he used it to its fullest potential. Ultrasonic Assassin. It was the name of magic that he used with Ayaka the first time they formed a team. This magic shredded him into pieces because of its powerful energy.

To fix the flaw and incorporate it into the Sound Levitation, he toned down the energy a little bit. Unfortunately, the energy produced by it was too low. He had tested it, and it only succeeded in throwing a small stone. That was why he took the Sound Insulation Magic to another level.

By creating a half-sphere behind the magic circle, Kai could release the energy from two sides of his Ultrasonic Assassin magic circle. The first one was from the front, and it had no problem. The second energy was reflected by the Sound Insulation Magic and flew to the front. This way, the magic circle had no problem in sending this big magical beast fly.

Oscillation Shield, Ultrasonic Assassin, and Sound Insulation. These three magic had helped him create support but offensive magic for him. Although he couldn't achieve the desired Levitation yet, he believed it was only a matter of time before he succeeded in his research in this area.

However, using three magic at the same time was easier said than done. If he didn't have twenty percent of magic power, he wouldn't be able to use this at all. He was grateful to Ria for bringing it to him at the right time. Well, she already promised to bring it to him a few months ago, so…

Kai shook his head and sighed. "I think it's time for me to learn how to shoot."

As he joked so, Eru roared. "You bastard!"

Suddenly, another voice also resounded across the battlefield. It was full of curse toward Eru as there were three crescent-shaped water blades flying toward him. "No, you are the bastard!"

"Boom Boom Boom!"
