The Magician of Sound

Meanwhile, in another place, Kai raised his swords while Neptune waved her staff. This battle was on a completely different level than any other fight on the other battlefield. 

Kai even teleported them to Argentina, far away from the current battlefield. He wanted to avoid the worst-case scenario after all.

"You have prepared to die…" Neptune squinted his eyes. 

He was right. Before leaving, Kai already asked Arba to bring his family members to Emulda Kalan and hide until the next opportunity came. Without Space Magic, Neptune had no power to go back to the battlefield to kill them yet. 

That was why it was a good time to flee, even if Arba needed to use her force to bring them away. 

Still, Kai never had the intention to throw away his life in this battle. 

He took a deep breath and answered, "That's a different case. I have no plan in dying."

"The feeling is mutual." Neptune faced Kai with a solemn expression. "I would have never thought that you could become this strong within such a short amount of time. Just like Gilgamesh… I guess this is a feature only humans can have." 

"I don't really care about what you're talking about." Kai waved his sword as the Sound Wave traveled from his sword to Neptune. 

Neptune struck the Sound Wave and redirected it to the ground before finding a colossal and deep sword mark on the ground after impact. 

Since Kai had attacked him, Neptune obviously had no plan in wasting his time anymore. 

"Rain!" Neptune raised his staff as the cloud began to turn dark and gather in their area. 

"Hmph." Kai harrumphed and tossed his jewel to the sky, trying to blow away the cloud. 

However, Neptune disappeared and his Crown Jewel returned to his hand. 

Kai raised his head and found Neptune above him. 

Then, rain began to pour down and became a deadly weapon for Neptune. 

A huge green-colored Magic Circle suddenly appeared in the sky, generating a low power Sound Wave that was only enough to stop the rain. 

Neptune, on the contrary, redirected the water to form a huge spear that struck the Magic Circle, shattering it. 

Kai then tossed his Jewel again. 

When Neptune was about to hit it, a pink Magic Circle transported the Crown Jewel to the sky, pushing all the clouds around the area, making sure no rain happened again. 

Neptune had predicted something like this; hence, he spread the rain. Using the water that just wet the ground, he formed multiple water spears, launching them to Kai in order to impale him. 

Kai's expression hadn't changed as he moved forward, heading straight to one of the spears. 

His sword cut through the water and split the spear into two before Neptune appeared behind him, waving his staff. 

"Water…"

"Sono…"

Kai spun his body while Neptune struck him. Their weapons collided with each other as water began to disperse in Neptune's direction while a shock wave pushed Kai back. 

Kai took a few steps back before grabbing the pebble on the ground. He then threw it while boosting its speed with his magic. 

Neptune caught the small pebble and turned it into dust, showing his extraordinary skin. 

"…" Kai squinted his eyes and grabbed his Crown Jewel, holding it together with his sword. "Sonokinetic Blade." 

The Sound Wave produced by his sword was amplified by at least twenty folds, creating an attack at an unprecedented level.

All buildings, trees, and ruins were cut horizontally as they soon got blown away by the shock wave produced a bit later after the swing. 

In one swing, Kai created a flat land within a one-kilometer radius. 

Even Neptune needed to avoid that attack as he didn't wish to unnecessarily use his power to contain that kind of attack. Still, he could understand why Kai became a protector. 

As if not wanting to be outdone, Neptune raised his hand. 

Hearing the movement from the ground, Kai leaped into the air and saw cracks appearing on the ground, letting the groundwater flow out to the surface. 

"You think you can defeat me on land? Water is all over the area." Neptune harrumphed. 

"But you can't manipulate the water in my body." Kai smirked. 

Neptune's expression turned serious. "Then, I will shove all this water inside your body." Neptune snorted. Suddenly, the brown-colored water rose and turned into hundreds of weapons from swords to maces. 

Kai hurriedly jumped to the side while creating his Oscillation Shield, protecting him from all those weapons. At the same time, those that chased him from behind met his Sonokinetic Blade that he dispersed to create a fan-shaped Sound Wave that obliterated all the weapons. 

After that, another Magic Circle appeared beneath Kai's feet and sent him behind Neptune. 

Neptune widened his eyes and hurriedly waved his staff, blocking Kai's attack. 

However, Kai's swords vibrated even stronger and produced a Sonic Boom, boosting his power and ultimately knocking him away. 

While flying, Neptune clutched his hand as the water rose from one side. 

Kai turned around and found a huge wave, reaching over eighty meters in height. 

"Oh, wow." Kai was impressed when he saw Neptune creating a tsunami with only groundwater. He then slashed his sword horizontally, splitting the wave into two. 

But this was where Neptune showcased his skills. The upper wave formed a hundred weapons while the bottom part carried the energy, turning the groundwater into a raging deep sea during the storm, trying to make Kai uncomfortable.

Kai tossed his Jewel to the weapon and dispersed the weapons while Neptune used this chance to point his staff toward Kai's back. 

His blue-colored Crown Jewel responded by infusing its power to create a raging water tornado. 

This one couldn't be compared to the one Ilareca used. 

Instead of spinning in one direction, it moved in all directions in that enclosed space. Anyone devoured by this wave wouldn't know where he should head because he would be spinning like crazy. 

Kai clicked his tongue and summoned his Oscillation Shield to block the water. 

However, Neptune played another trick when a dragon head rose from the water and devoured him.

"Annoying." Kai's Crown Jewel returned to him and remained floating on top of him. It then generated the Sound Wave that blew the water away, ultimately destroying the dragon's head. But Neptune's water tornado managed to withstand that powerful shock wave.

"Hmm?" Kai furrowed his eyebrows. "As expected from a protector, I guess." 

He slashed the tornado diagonally using his Sonokinetic Blade. 

The Sound Wave cut through the tornado and continued to head toward Neptune. 

Unfortunately, Neptune had recovered and stood above the water. Instead of moving away, he formed another water spear with the same ragging current like the tornado and sent it to the Sonokinetic Blade. 

The two collided. The water was blown back while the wind pushed everything behind the Sonokinetic Blade backward. 

Neptune took that chance to devour both of them by summoning another dragon head from the water, suppressing both of their attacks. 

"This is good." Neptune smiled confidently. Even though Kai was strong, he still couldn't see himself defeated by Kai. 

On the other hand, Kai was curious about something. He asked with a poker face. "If you have this much power, why don't you just challenge King Gilgamesh with your strength instead of relying on cheap tricks?" 

Obviously, Neptune took it personally and waved his hand, creating a crescent-shaped water wave that ran on the surface of the water.. "There is no need to answer your question."
