Boom.

The starfish was launched to the side from that explosion, giving Kai an opportunity to strike him a couple of times.

"Kh!" The starfish clenched his teeth and saw that there were two spots that began bleeding. Despite the protection from his hard skin, Kai seemed to have attacked him enough, especially with his aims.

He kept attacking the same area continuously even though the starfish had no problem in taking it. Yes, Kai had been in advantage this whole time.

"It's too shallow." Kai turned around and planned to hit a few more times, but the starfish already recovered and blocked all the hits.

Kai didn't give up and kept pinning him down on the ground with relentless attacks until he felt something was wrong.

A bullet suddenly hit the starfish's hand, allowing Kai to deliver a few blows.

Kai widened his eyes, never expecting that Isabelle would help him.

He indeed heard her shooting and the bullets weren't flying to the turtle. It turned out that she shot between the turtle and the starfish before the two bullets hit each other, bouncing off to two opposite directions.

The first one hit the turtle's barrier, making him miss the second bullet. As for Kai, it was the best support he could get.

"This is enough!" The starfish was angered before the dirt around them emerged from the ground, trying to pierce Kai.

With his ears, he had heard the movement first and jumped backward, looking at the starfish with a serious expression.

"I have underestimated you, but this time, I won't. My name is Serta. Make sure to etch this name into your memory because it's the name of the man who will kill you."

"Hmph." Kai snorted. "Do you think you are qualified?"

Serta quickly leaped forward. He struck the ground with his shield as many the dirt spiked all around Kai.

However, Kai wasn't scared of this attack. He simply struck the spikes with his Super Sonic Sword where the rest was handled by the Sonic Boom.

Kai had no problem destroying the spikes and headed straight toward the starfish, planning to cut him again.

The starfish charged with his shield on the front, pushing Kai back.

"Sound Blast."

A green magic circle appeared beside them as it blew them several meters away, stopping the charge.

He then used another Sound Blast to launch himself to the starfish and struck the sword with both hands.

Due to his shield getting blasted by the momentum, he shouldn't have the power to stop his attack, but surprisingly, the starfish's hand turned into metal before summoning the rocks underground to come to the surface.

The rock covered his hand as he caught Kai's Sonic Sword.

To his surprise, the rock was harder than his Sonic Sword, baffling him. Even so, he didn't give up and ended up trading a few more times but to no avail.

"I have only fought with your type of weapons recently just to test you. Since you have angered me, I should start getting serious now." Serta clenched his teeth while covering his body with the stones that happened to be harder than his body even though it was just a regular stone from the ground.

Kai furrowed his eyebrows and took a deep breath. "This is going to be a troublesome opponent."

Serta jumped forward and threw a punch, only to meet Kai's Sonic Sword. However, the result remained the same.

Kai lost and got pushed back. Before Serta managed to pin him on the ground, Kai's Sound Blast already helped him escape.

He then retreated a few steps and muttered. "Even with my current strength and exoskeleton, I am still not a match against the protectors? What should I do now? There are three protectors coming here, so we really need to do something as soon as possible. However, I can't see it."

"Out of my way!"

Bang.

Kai and Serta turned around. He knew that someone was coming, but they never expected that someone really breached the magical beasts to help Kai.

And someone who dared to be this daring was none other than Brad Matthew. He had been sitting in the back this whole time but had gotten bored and chose to wreak havoc on the very front.

When he saw Kai having trouble, he thought this would be the best time to show that he wasn't a pushover.

The starfish quickly raised his hands to stop the spear on Brad's hand, but Brad made an unexpected movement by placing his hand on the ground.

Two magic circles appeared, one below his hand and the other one was above Serta.

"Ice Summon. Meteorite." Brad smirked.

As soon as he poured enough magic power into it, a huge chunk of ice emerged from the magic circle, falling down.

"Take this, you monster." Brad thought that if the rock was hard, he just needed to handle him with his weight. There was no way that this Starfish could stop a big rock like this.

"!!!" Serta looked up and absorbed more and more stones from his surroundings before he formed a support pillar for his arms to stop the ice.

Bam.

The shock wave of stopping more than a ton of ice block shook the entire battlefield, blowing the magical beasts near them.

"Do you think I can't hold this? Let me show you what will happen if I use your own Ice Cube to destroy your army." Serta smirked as he planned to throw the ice forward.

Suddenly, Kai's voice resounded in his ears. His tone was cold as if a death reaper just passed him.

Serta widened his eyes and glanced, knowing it was too late.

Kai used the split second he focused on Brad to slash him a few times, destroying his armor and grazing his body. The wound was deeper this time, so his strength should get lower after this.

"Gah!" Serta spat a mouthful of blood before the ice crushed him on the ground.

"A perfect timing indeed. As expected from a three-star general." Kai smirked and looked at Brad's face.

"So, where is my thank you?" Brad rolled his eyes.

"When you truly help me in defeating him, okay?" Kai smiled before seeing how cracks began to appear on the ice surface before it was getting obliterated by Serta. It shattered into thousands of pieces, crushing many magical beasts to death.

Of course, many of them flew toward the humans, but Dun managed to react and protect them with his barrier magic.

"You! I am going to kill you." Serta roared as he released all of his magic. "I am going to show you the difference between you and me. I will crush all the humans you hold dear."

"Serta!" The turtle shouted his name to call him back from his anger, but the latter ignored him.

The stones from the ground emerged in a volume that no one had ever seen before.

Kai retreated to Brad and said, "This is going to be bad."

Brad couldn't answer immediately as he gradually raised his vision as Serta began building his body.

"Scarlet Explosion."

Ayaka's voice echoed on the battlefield. Knowing the danger that Serta would possess, she thought it would be her time to step up, but a barrier appeared, stopping her explosion.

"Young Lady. Please focus on this old man…" The turtle smiled and protected Serta until he could fully function as a giant golem.

However, Tasha finally acted on her own as she appeared on the battlefield, right behind Serta. She placed her hand on the ground and created a Teleportation Magic Circle.

After seeing how the turtle couldn't help Serta, the octopus shot out another beam of light, planning to disrupt her, but Rain managed to create the same barrier as the turtle, stopping the attack at the last second.

"Where do you think you are aiming? Your opponent is me." Rain smiled and clapped his hands, summoning two giant translucent barriers to crush the octopus.

Before it hit him, the octopus used all of its legs and jumped to the sky, aiming at the soldiers instead.

"Sh*t!" Rain realized the blunder and planned to head back, but Dun already leaped to the air and summoned a large barrier.

The octopus ended up hitting the barrier.

Unfortunately, Dun's barrier was weaker than Rain's, ending up cracking before the residual shock wave blew him to the ground.

The octopus didn't let this chance go away. He waved all of his legs and created eight crescent shapes that would soon kill so many soldiers.

Boom Boom Boom.

A series of explosions were heard.

Dark Michelle was in the air together with the real one. She destroyed four of them with four scythes while the real her cut two. The other two were shot by Isabelle's two sniper rifles.

Finally, the octopus landed on the ground and made the ground vibrate for a second.

Kai smiled when watching that they safely endured all those attacks, leaving Serta as his target.

"What?!" Serta widened his eyes as he found that Kai was about to attack him.

After getting the momentum from doing all that, Kai used his Sound Blast to send him flying straight to Serta's head which was above forty meters.

He struck with both swords even though he knew that he wouldn't leave a scratch on this body. But Kai's real aim was to throw him off balance and it succeeded.

Serta began to fall on his back as Tasha's Teleportation Magic was activated.

The next second, Serta realized that he was falling from the sky and soon would fall upon the magical beasts.

The turtle obviously couldn't let him fall just like that. He created a translucent barrier with a forty-five degrees angle, planning to catch Serta and letting him slide the barrier so his big body could swipe the human soldiers.

"Not good!"
