The Magician of Sound

"Then, let me invite you to a place under my rule," said the Whale Queen as the platform below Kai's feet expanded, forming a transparent sphere like that of a bubble.

"This is…" Kai glanced left and right.

"It's just to make sure you don't feel the water pressure and have quite a long time to breathe."

The Whale Queen even expanded it to twenty meters in diameter so Kai could breathe freely inside.

Kai nodded. He was thankful for the gesture, but he wondered how he should look around inside the sea.

Unfortunately, the Whale Queen didn't care about his opinion and quickly submerged.

She brought the bubble with her and dove to the sea bed.

At first, Kai could see thousands of Magical Beasts. Even a normal fish had considerable power under the sea, so he understood why they couldn't cross the sea yet.

Kai looked around, staring at the deep blue sea. The light still reached the water near the surface, but as they gradually got deeper and deeper, the light became even scarcer.

He only had a vision around thirty meters in front of him despite only diving around three hundred meters inside. Luckily, he could still hear various sounds with his extraordinary hearing even though it was quite suppressed by the water.

"…" Kai narrowed his eyes and looked down, falling into deep thought. He muttered inwardly, 'Hmm, my ears don't touch the water directly, so the hearing that is supposed to be stronger is gone. However, I can still hear around one kilometer in radius, so I guess this is fine.

'I can sense several magical beasts that seem to be releasing ominous presence. Though, the moment I accept the Whale Queen's invitation, I have entrusted my life into her hand. After all, I won't likely survive if the bubble pops out.'

Kai let out a long sigh and kept observing his surroundings.

They kept descending to several thousand meters before Kai suddenly took a step back in shock. "This…"

"It seems you have heard it." The Whale Queen let out a sound before looking down. "Take a look at the bottom of the ocean."

"…" Kai dropped his jaw to the ground when he saw a powerful source of light on the bottom of the sea. In fact, he soon realized it was multiple sources of light.

There were lamps and other things that generated light to brighten the seafloor.

"This is…" Kai looked at the Whale Queen while frowning. It was true that this kind of sight was nothing but amazing. However, what shocked him the most was the fact he heard people talking. It wasn't any other language but human language.

Unfortunately, he couldn't understand their language since they seemed to be talking in a traditional language. Even his device couldn't translate the language.

"Who…" Kai muttered and tried to see the bottom of the ocean.

"You will know when you enter." The Whale Queen reached the bottom in a minute and laid down on the ocean floor next to the light.

It was at this time Kai could finally understand what was under the sea. There was also a giant bubble that expelled any water. Inside this half-spherical bubble were multiple light sources and houses as if there was a town on top of the ocean floor.

"A human town?" Kai furrowed his eyebrows as his bubble gradually came closer to the bubble.

When they made contact, the bubble began to merge together as the Whale Queen said, "Please come in."

Kai nodded and took a step forward, jumping to the floor that seemed to be made of limestone. There wasn't cement or asphalt, but this limestone had been shaped cleanly to make a smooth road.

He looked to his left and found multiple houses. Those houses had unique shapes as he saw a coral-shaped house with many holes around it. There was also a house made of multiple stones stacked together.

He turned to his left, he found two people, male and female. Both of them were stark naked, but there wasn't a slight embarrassment on their faces as if this was a natural thing to do.

The female had slightly pale skin but matched her silver hair. However, he soon noticed that the male had similar facial features. Both of them had silver hair and eyes. Their noses were quite big, but their lips were small.

The male had abs and strong arms, but the female seemed to have nothing of that. Instead, their skin was paler than the male.

Their height was around the same as him and Kai couldn't really say they were unhealthy since they seemed to have been living like this for a long time.

When the two saw Kai wearing clothes, they were bewildered.

"Gakuka?"

"Gakuka?"

Suddenly, an old lady appeared next to Kai. She had silver hair and silver eyes. And like him, she also wore beautiful white clothes and robes that covered all her body.

To his surprise, the old lady said in a Sea Natural Language, which was learned by most of the creatures under the sea.

"(I have returned.)" The old lady smiled at Kai before glancing at the pair on the side.

The couple surprised him again when they suddenly fell on their knees, placing their heads on the ground as if greeting the old lady.

"(This is…)" Kai made a weird expression, staring at the old lady. "(Are you the Whale Queen?)"

The old lady nodded and said, "(It's an underwater city I have created in the past due to a certain promise.)"

"!!!" Kai widened his eyes and took a step back, remembering a certain person. "(Are you talking about Rapakha?)"

"(Ah, there is also that man. However, I'm not talking about him. Him in my mouth was the world's strongest human who could fight two Protectors at once despite having equal power.)"

Kai instinctively said, "(Is it King Gilgamesh?)"

"(He was an old friend.)" The old lady nodded and turned to the couple. "(Anyway, gather all the people in the center. I want to introduce someone to all of you.)"

"!!!" The couple panicked for a second and nodded their heads furiously before running away as if completing the old lady's task.

"Where is this?" Kai asked.

"In the past, I promised an old friend to preserve humanity because of a certain fate that couldn't be predicted for the past few millennia. I agreed to do it because of his wisdom. He was quite a frank man who thought nothing about politeness.

"He talked to me casually to the point I thought they were rude…"

"Ehm… Sorry?" Kai made a weird smile while scratching the back of his head.

"It's fine. After all, that personality of his was the one that bound everything together. Not only can he easily make friends with others, but the people are willing to follow him. Yet, he was the scariest when he fought.

"Either way, several millennia had passed, so I thought it was the time to tell you this promise… Which is this place." She raised her hands as if pointing to this whole place.. "This place is called Shekmesh, the place to preserve humanity."
