The helicopter flashlight was the signal for the cameraman to record the battle.

Kai smiled and waved his sword. "Sonokinetic Blade."

​​

This time, he used a bit more power to make his Sonokinetic Blade unstable, resulting in the blade becoming even wider.

"Huh?" Kerza furrowed his eyebrows as he didn't understand why Kai would mess up in this situation. He simply destroyed the Sound Wave before him while leaving the rest to destroy more than ten houses.

To their surprise, the houses that took the direct hit got split into two.

All the people in that helicopter were astounded as they finally saw Kai's real prowess.

Although they didn't understand, all four of them leaped to Kerza while unleashing all their attacks.

"Authority Blade."

"Ice Circulation Magic. Dragon Head."

"Lightning Discharge."

"Ice Saint Sword."

Roselyn's Authority Blade was grasped by Kerza even though it left a quite big sword mark on the ground that was even visible with naked eyes.

Sofia's Dragon Head swallowed Kerza from above. However, Kerza soon shattered it into pieces, albeit the residual ice began to freeze the road, covering the road, the wall, and even the house with a thin layer of ice.

Arnaud's Lightning Discharge was repelled to the side by Kerza's tentacle, but that attack left a half-sphere trail on the ground as if something big just chewed the road before exploding, turning a house into rubbles.

At the same time, Jules's Ice Saint Sword was avoided by Kerza with a simple move, which was leaning to the side. The sharp sword continued to expand until it struck three houses in succession, creating a hole through them.

All of them used their strongest attack to give the biggest impact the world could see. They might not know Kai's plan, but they understood the gist of it after knowing Kai for a while.

However, all of their attacks were rendered useless while Kerza blew them away with his wind again, laughing out loud. "Whatever your plan is, there's no way you can fight me. Even if you come together with hundreds of thousands of soldiers, it's still not enough. But… that flashlight is annoying me."

Kerza looked up and formed a huge tornado to swallow them, but Kai leaped into the air with his Sound Blast and formed a huge Sound Blast to counter the wind. Meanwhile, Sofia followed his movement and froze the tornado with her Ice Magic.

Kai stepped on the frozen tornado while glancing at the people in the helicopter. "It's better for all of you to retreat and don't come back. This battle may destroy this neighborhood. Don't worry. As long as we are here, we will continue fighting to our last breath to repel this intruder."

Listening to Kai's voice, the pilot nodded while staring at him in the eyes. Although he wanted to salute, he had his mission from Kai and quickly flew away, not wanting to be his burden. The battle itself was insane, even from an amateur's perspective. At this level, one mistake would literally end the match.

If Kerza took them as their hostages, it was the worst situation for Kai and the others. As someone who retired from the army, the pilot left the scene quickly. They also had enough footage anyway.

Kai then dropped to the ground and smiled. "This is not over. You will die in our hands. That's all."

"Then try it!" Kerza snorted and charged forward.

The battle became even bigger. As Kai said earlier, the neighborhood gradually turned into a ruin, making one wonder whether they could live here anymore. Even the orphanage wasn't spared from all this mess.

Kai kept using all his power in order to suppress Kerza while the others attacked him, but as a result, he got more wounds than anyone else.

In just a mere ten minutes, his body had been covered with wounds while his clothes were drenched by blood. The rest had a similar condition, but they had another problem which became their main problem.

Their energy and Magic Power were used up. Their movement gradually became dull and their magic started to lose its power.

It was even faster for Arnaud and Jules, allowing Kerza to gain back his momentum.

At that point, Kerza used his all to beat all of them and exhaust them. However, with Kai and the others' persistence, they also managed to strike Kerza a few times, resulting in him losing one more tentacle and some wounds on his body.

His movement might become duller, but it couldn't be compared to Kai and the others' condition.

After another ten minutes, Roselyn had been sitting on the ground, leaning her back on a destroyed wall. Her head was down and her consciousness had grown fuzzy.

Sofia was lying down on her belly, staring at Kerza's abnormal strength. Jules had a similar pose as Roselyn, but he wouldn't fall far from his granddaughter. He would surely protect her granddaughter even if it were the last thing he did.

Arnaud was on his knees, leaning to a small pillar that was about to collapse. They were one step away from the unconscious. Yet, Kai pulled it back with his action.

Kai panted a few times and stood by his feet. He had no strength left to oppose Kerza, but his gaze remained strong. He stepped forward and placed his body in front of everyone who had no strength left to fight. All their bodies had been covered with blood and wounds, so it wasn't possible for them to move anymore.

"Kai…" Sofia wanted to raise her hand to reach his back, but she had no energy left to even move her finger. Even her voice was shaking. She wished to tell him that it was alright for him to escape, leaving them behind.

Kai was someone who would eventually come back to get his revenge, so she had prepared to die in this battle.

Kerza, on the other hand, had some wounds on his body and his energy was depleted as well. He might be weaker than the protector Kai met in Latvia.

Even so, with them becoming this weak, the chance to win was zero. Even Rena wouldn't make much difference on this occasion, let alone with her still flying in the air.

"You don't have anything left. Since you're so brave, I will kill everyone painlessly." Kerza snorted and paid his last respect to Kai. Even if they were his opponent, Kai was still the Human Race's Protector. That identity would always stick in his back for the rest of his life even if he were unaware of it.

"Hmph! Do you think you have won?" Kai snorted.

"Of course. You can't even do anything to me. Even if I touch you a bit, you will fall to the ground." Kerza made a smug smile, celebrating his victory.

Suddenly, a smile appeared on Kai's face as he stated, "You couldn't even kill us within thirty minutes. What a joke."

"What did you say?!" Kerza got angry because he never expected the person who would soon die in his hand to even have the time to mock him.

"I already said… Everything will be resolved within thirty minutes. Now that I have accomplished my objective, it's time for you to die." Kai smiled.

"You're the one who is a joke. You can't even see who's losing! I am disappointed in you. I have changed my mind, I will torture you first before killing you." Kerza released his killing intent so strongly, enveloping everyone in this place.

Kai only put a finger in front of his mouth as if telling him to stay quiet. "I can hear it, you know."

"Huh? It's useless if you just want to buy some time." Kerza walked forward and approached Kai slowly, making the one behind him worried. They all wanted to rise and help Kai escape, but none of them had the strength to do it.

They could only see Kai's last moment with regret.

However, Kai simply continued without fear in his eyes. "Right back at you… After all, I can hear it… The sound of humanity's strongest magician."

As soon as he said those words, Arba suddenly appeared right above Kerza. Her fist was also covered with a wind sphere like Kerza, but this one was much stronger than him. At the same time, Aston came to Kai's front while using his power to create a transparent sphere to keep them safe.

"Beating His Majesty like this is a capital offense. Prepare to pay it with your life, vermin." Arba's tone was extremely cold.

"!!!" Kerza turned around and saw Arba's fist hitting him right in his face.

She quickly pushed him to the ground with that punch before releasing all the compressed wind she used to cover her fist.

That compressed wind released a terrifying power as the ground began to crack and turn into a huge crater that engulfed at least a hundred houses in their surroundings. At the same time, the powerful shock wave also swept the houses as if a hurricane passed this place.

Boom.
