"Thank you." Kai smiled at them, knowing they had been waiting for quite some time. He asked, "I have done everything I can in this place and I think it's time for me to leave.

"Let me check a little bit. I've understood thirteen languages, including your language. Meanwhile, I have entirely removed the restriction that keeps a portion of my magic power inside my body, so my sister can have that power permanently. Of course, my current magic power is higher than the original one that I've gotten since the moment I was born. If it's necessary, I can ask my sister to return that power anyway, so it's not a big deal.

"Then, I think I can release my Sound Wave to one particular direction. Although it's not going to bend around, curve, or even create a loop, it's already enough for my current state. I'm planning to wreak havoc in this world a bit to test my power and keep getting stronger. I know the limitation, so no need to worry." He paused for a moment and asked, "How are the two girls doing?"

"Replying to my King, if both of them work together, I believe they can take down an S Rank Magical Beast, like the mole you fought together without sustaining any injury." Aston summarized their improvement in an instant.

"That's great. It should be enough for the payment." Kai nodded before thinking about his other girls. "I'm wondering if I can still give a bit of pointer to a few others.."

"That depends on who they are.." Aston felt a bit troubled but replied nonetheless.

"They are my girls. I'm not doing it for my family and the others.. Only my wives will accompany me for a long time, so.." Kai sighed.

Aston contemplated for a moment and replied, "I think you can do it as long as there is supervision from our Mind Magic User that can remove the information swiftly. We can try to put our trust in them not to give any information to the world, but we still need this kind of supervision."

Kai closed his eyes for a moment and sighed, "That's fine. It's better to have them stronger to avoid any direct confrontation such as favoritism or something. Although they won't say it directly, I feel like the feeling will appear in their hearts intentionally or unintentionally. That's why I want to do this."

Aston understood the situation and offered a solution. "We can understand. How about letting Leah and Devain return together with you? Leah has Mind Magic, while Aston is a Space Magic User. We have sneaked in the US Base and created our own identity, so they will be registered as such.

"Of course, it will be suspicious if they just appear out of nowhere, so we can put another identity to them as your parents' bodyguards. Aston can help Leah to go around the base to teach them from time to time."

Kai was thankful for their generosity and nodded. "Yeah. I think that's fine. But I won't force Leah and Devain to accept this request."

Leah smiled and politely nodded her head. "It's my pleasure."

Devain also agreed without hesitation. They considered Kai as their king, their friend, and the one they respected so much on a personal level. Even if their king was required to sacrifice them, they would offer their lives without hesitation.

"Thank you. Well, it will be three months later, so you don't need to worry about it. Besides, I'm planning to take on a long mission as soon as we reach home, so we can train during the mission where no one can supervise us." Kai explained.

The two nodded, understanding his situation. They had three months to prepare, so they might get another training session with Aston and Arba after this, but they didn't really mind.historical

After agreeing to Kai's request, Aston then continued his matter. "Before leaving this place, I would like to show you one more place that you need to know. Please follow me."

Aston turned around as the other three followed him without hesitation. Kai narrowed his eyes as he didn't know what kind of thing he wanted to show him, but he decided to walk behind them.

They went through another labyrinth before they found staircases leading to the underground. This was the first time he reached this place, so he was quite curious about what kind of thing was hidden in this place.

The place was pitch-black as there was no lightning. But Aston kept walking forward as if the darkness didn't bother him. After ten steps, he took one step to the right and placed his hand on the hidden switch, turning all the light inside the room on.

"!!!" Kai squinted his eyes to adjust with the lightning and looked up, finding a long electric lamp. It kept going until they needed to turn left a few meters in the front, leading to a certain place.

He then lowered his vision and looked at the wall. The size of this passage was around three meters wide and four meters tall, making it quite spacious. There was no pattern on the white polished limestone, so he couldn't know what kind of place this passage led him to.

After getting enough light, Aston continued walking and turned to the left. It was when Kai found another spacious room underground that led him to other staircases going downward.

"Hmm.." Kai narrowed his eyes and asked, "What is this place?"

Arba slowed down and smiled at him. "I'm sure you will be surprised to see it."

Kai tilted his head in confusion until he reached the room. It was vast to the point he thought there was a smaller version of this gigantic building he was in. The bottom of the room was more than ten meters below him as he found quite long staircases waiting for him.

Right after the staircases, there was a red carpet that led him to a one-meter stone pillar. What took his attention was not the pillar but the translucent gem floating above it. The jewel was crystal clear to the point he could see through it without focusing his eyes.

Below the pillar was a magic circle that had been embedded for a long time. It looked to be inactive, but Kai quickly recognized what this place was.

"Ehm.. That floating gem, white pillar, and magic circle are.. It's like what I'm thinking, right?" Kai scratched the back of his head, feeling the situation would end up getting complicated soon.

"Yes. They are the Human Race's Altar. The Altar that has been hidden for thousands of years. The White Pillar is the Altar's body, while the Magic Circle is the fuel. The floating gem is a kind of crown that allows you to activate the Altar.

"There are two main functions. First, the Altar can be used as a catalyst to bring catastrophe to the world. Second, the King can actually use the Magic Particles in the air for your own personal use. That's how a Protector becomes a walking disaster. Even with all of your power, you won't have enough magic power to use to create multiple natural disasters after all.

"Sure, if you keep going at this rate, you can summon one disaster after fifty years, but it's kind of the limit of the Protector, so yeah, unless you have the 'Crown', I don't think you can defeat another protector." Arba sighed, knowing that explaining things and making him believe the explanations were two different things.

That was why she added another thing, "We don't plan on giving you that crown because I believe your concept of Altar is only related to the first one. That's why you can fight against others first and learn more about your power as a protector before making your decision.

"If you choose to get this crystal, we will always be waiting for you. I believe that's also when we're making our move to help you." Arba glanced at Aston, telling him that both of them might only move when Kai actually became a genuine 'King'.

"That's.." Kai contemplated for a moment. Although he understood where they were going, he still couldn't trust them one hundred percent.

If it came to this, he probably needed to visit Ishii to ask about it. He also remembered the Pink Dolphin and the Sloth in the Amazon Rainforest.

Still, Kai planned to return to United Asia to settle things with the Katsuragi Family, so he thought about asking Ishii instead of the two.

While he thought about it, Aston already knew his answer and said, "Since we've shown you the most important thing in this place, I think we should wrap it soon. I'm sure you don't want to let the two girls wait for too long, right?"

Although Kai wanted to explore and observe the Altar for a little longer, he knew he could do it next time if he really needed it. Hence, he hesitantly nodded his head. "Yeah. But I want to ask you two things before we go back."

"Sure. Ask us anything."

"First, who was spreading the rumor that our Altar is missing?"

"King Gilgamesh ordered us to spread the information because there was a chance that they were going to steal it. If we didn't have the Altar and Gem, we are simply a race without power to fight back until we reclaim what is ours."

Kai nodded and asked his other question. "Do you think it's alright for me to talk about it with the other protectors? Of course, I'm not talking about the location and such."

"Yeah, it's fine. As long as you know that this is the most important thing to our race, it's fine."

"I see.." Kai contemplated for a minute before turning around. "Let's go back then."
