"Interesting." Arba widened her eyes and slowly rose from her position, straightening her posture and facing Kai politely. "It's my honor to meet you, My King, Kai Carter. My name is Arba Eaon. I would like to apologize for my actions."

Kai smiled and nodded. "Nice to meet you."

From the start, Kai already knew that Arba intentionally antagonized him because she wanted to test two things. The first would be his temperament. How much anger could he contain? If his pride was hurt by something like that, she needed to reconsider teaching him the power befitting that of a Protector. After all, the world might become a dangerous place to live if such a person actually held this much power.

At the same time, he wanted to see how developed Kai's ears were. Although she intentionally did it, her tone and heartbeat didn't change at all, so it was hard for someone to pick it up. However, Kai seemed to be better than she thought. Kai could only find this flaw was due to the fact that these two talked in English instead of their common language this whole time.

So, she politely greeted him and apologized.

"As much as I want to talk with all of you here, I believe we should finish our purposes first since I can't really let the people outside wait for too long."

"That's what we would like to ask first, My King. Why would you bring an Oni to this place?" The old man, Aston, asked.

"He is just a husband wanting to see his wife's family while fulfilling his wife's wish. That's all." Kai shrugged.

"Aulia Kernell?" Aston narrowed his eyes and turned to Davian and Leah, who nodded their heads, confirming Kai's words. He then looked down while contemplating, "I see. I can understand if that's the case. He can stay for a period of time, but I'm afraid he can't live here forever."

"I've met with the Oni Protector and from my point of view, I think you can let her stay there. I'm sure she won't be mistreated. Of course, her own family will decide that after discussions."

Aston agreed without hesitation since it was the best option for them. "I understand. Devain… Can you handle this matter?"

"Yes." Devain nodded and left the room, fulfilling the mission as soon as possible.

"As for the others… I am not sure what My King is planning to do."

Kai contemplated for a moment and asked, "What is the rule of this place?"

"Does My King plan to keep their memory intact?"

"Yes. I think you can understand my intention, especially with the fact that this place has actually followed the news all over the world with their technology." Kai smirked and looked at Aston with a serious expression.

"Indeed," Aston admitted that the best course of action would be allowing them to get some information from here. Unfortunately, they still needed to erase a portion of their memory. "Still, I would like My King's permission to erase their memory. We can't allow them to know the location and a few other things. If it's about our culture and some information, I don't think we have a problem, but we can't afford to have many people aware of us.

"Even the fact that they have some sort of way to pinpoint our location is already too dangerous for us. And this will apply to your wife as well." Aston looked down in disappointment. He didn't want to do this, but the rule stated to protect the entire city.

Kai let out a long sigh and said, "It can't be helped. However, make sure you don't touch anything else. And how do you know she is my wife?"

"There are two ways. First, I have been following My King's news, so I know that you have some sort of relationship with Sofia Campbell. Second, I can use Mind Magic. It's easy to see your affection toward someone."

"I see. It's quite terrifying magic, eh."

"I would like to apologize because I can't control what I can see."

"Nah, it's fine. This also means that I don't even need to tell you about such a thing and you will understand what you need to do. Seeing your composure, I believe you are not someone who will easily make a wrong choice."

"Thank you very much." Aston lowered his head and continued, "In that case, I shall ask Leah to prepare the guest rooms and have them stay there first before explaining all the things they need to know."

As soon as Kai nodded his head, Leah left the room and guided them to another place.

At the very least, he could monitor them with his ears. With two S Rank Magicians, they should be fine for the time being.

"So, what are we going to discuss here?" Kai asked.

"That depends on your wish." Arba finally joined the conversation with a nonchalant tone. She seemed to have gone back to her carefree state.

Kai didn't mind such a thing since it would make this meeting a bit more casual. But Aston simply couldn't let it go and glared at her.

"Arba!"

"Why? Why are you so stiff, old man?" She shrugged. "Even if he doesn't tell me anything, why are you trying to find faults in me?"

"You know about it yourself." Aston clenched his teeth, wanting to beat her up. Unfortunately for him, it was just a pipe dream because Arba's magic was more suitable for fighting than him. In fact, he couldn't even hit her once if they fought against each other.

"What did you say?" Arba narrowed her eyes, planning to beat this guy again.

"Ahaha…"

Kai's chuckle suddenly stunned both of them as the two fell silent, staring at him. Kai was amazed that the two would stop with just a chuckle and decided to give them an answer. "I want to learn other languages and get stronger. I'm afraid a certain protector will make a move sooner or later."

Arba and Aston turned serious the moment Kai mentioned a protector. They had been following the news about Kai, so they knew which protector would make a move.

They exchanged looks and nodded in agreement. Aston then asked, "It seems to be the case… But I wonder how long My King will stay in this place? Teaching you something will require a long time, so…"

"Well, I think I can stay for three months. After that, I need to return… In fact, I need to prolong my stay in the EU Base for this. And due to this, I will be leaving my team in the US Base for six months…" Kai let out a long sigh as he couldn't really spend too much time.

Aston took a minute to calculate everything and replied to him. "In that case, I will be teaching you the major languages. Instead of learning all the languages, I will be teaching you one Major Language every week. Since you say you have three months, it means I can teach you thirteen to fourteen Major Languages.

"The languages will consist of Bird Language, Wolf Language, and so on. I will give My King the details later. Of course, the first thing you will need to learn is none other than our Akkadian Language. If you know this language, the others can be finished within a week even with another training."

Kai didn't know how impactful their languages were, but this was his first step to protect his family in the US Base. Unlike the previous time, he didn't plan to run away again if a powerful enemy came to him.

"I understand. I will leave it to you." Kai nodded.

"In that case, I will be teaching you combat techniques." Arba smirked. "Well, after watching your news, I believe you are good enough already, so I don't need to fix your basics or anything. I will focus on a few things instead. How about it, Aston? You don't have a problem, right?"

Aston clenched his teeth and looked away.

Kai only smiled while watching their conversation. Even though they looked like they annoyed each other, they didn't seem to hate each other.

Seeing there was no objection from Aston, she raised her hand along with three fingers, explaining. "Then, I will be teaching you three things. The first will be the way to increase the Magic Particles inside your body. Because you're the Protector, you should have the natural affinity for this. Although you need time to get stronger, you should be able to one hit an S Rank Magical Beast within six months… That I can guarantee.

"The second one will be Magic or the more popular term in this place… Mystic. As you know, the way we're handling Magic Particles is different from what you know. Hence, I will teach you how to control the Magic Particles. I'm sure you can do something big with this technique, especially if you have enough Magic Particles in your body.

"Last but not least, I will be teaching you S*x technique."

"Hold up!"
