Not long after the playing session, they returned to the inside. It was the time for the kids to study many things.

Kai could find many subjects, starting from physics and such. The kids obviously didn't understand most of them, but they were asked to learn to see what kind of things they loved. It was at that time the caretaker started planning their future carefully.

Kai helped them with what he knew. Obviously, half of them were actually interested in fighting for the Union like their Big Sister Roselyn.

Some kids asked about Kai's experience and stories about the front line. In the end, Sofia was the one telling the kids about it since it would be good to see it from the third perspective. Kai also wanted to see what kind of perception Sofia had about him.

The stories were pretty simple. She only told them about Kai's power a bit, telling the kids that he could cut metal like cutting butter or lifting a car with his strength alone.

After that, she told the kids about his strategy in the war and how Kai ruled the entire battlefield with his strategy.

They obviously loved to hear it. Without even listening to them, the kids were staring at Sofia in amazement.

While they were listening to the kids, Roselyn and Sonia began to prepare food for dinner.

Suddenly, Felice tugged his hand and looked at him with a serious expression. "Big Brother, can I ask you about something? Ehm… If possible, in private."

Kai thought for a moment and nodded. He then pointed at the slightly less crowded area and asked, "How about there? I can use my Sound Insulation Magic too, so no one can listen to our conversation."

"Well, if possible, I would like to talk in a private area like my room, but I guess… It's not possible, huh." Felice looked down, feeling a bit sad.

"Unfortunately, yes. I have my own integrity and rules that I won't break." Kai gently smiled. There were two reasons why he wanted to avoid talking in a private area. The first one was to prevent any rumor about him staying in a room with a girl, let alone an underage one, even though the legal age had been lowered to 15 years old due to the apocalypse. Secondly, he didn't want to make his girls jealous or had the need to lie to them about this private thing.

Felice understood his concern and nodded, following him to a slightly less crowded corner.

Kai then activated his Sound Insulation Magic and asked, "So, what is your question?"

"Actually, I don't have any vision about my future. I don't know what I want to do… It just… looks like a black and white world." Felice sighed.

"Being a genius is not easy, eh?" Kai smiled.

"Big Brother is also a genius." Felice shook her head. "All your military exploits can only be achieved by a genius. That's why I thought Big Brother could understand me…"

Kai smiled and patted her head. "For me, I have a drive that forces me to keep going no matter how hard it is… No matter how boring it is… As long as I remember what drives me, I can continue. Do you have that?"

Felice furrowed her eyebrows and shook her head. "Although I hate myself to say this, I'm indeed grateful for everything Big Sister has done for me, but it's at the level where I will pay her back and end it there. May I know… Never mind."

"The only thing that drives me is my family. I suffered through my childhood because my ears are special, forcing me to listen to something I don't want to hear… Imagine, when you are only a few years old, you will listen to the neighbors telling you you are weird and don't want their kids to associate with me or your friend actually talk bad about you behind your back… At the same time, all those voices are replaying in my head at the max volume."

Felice looked at Kai with her mouth slightly open before shaking her head helplessly. "I might have gone crazy. Big Brother is strong."

"Nope. I'm not strong. I have gone crazy, you know. However, the one thing that keeps me going is the fact that my family has never once said anything about my defect and such. They never complained, discussed the hardship of raising me, or cursed about these unique ears.

"I want to repay them and take care of them for the rest of my life to show my gratitude for raising me. In my journey, I find someone who becomes my strength and keeps pushing me forward. I want to protect all of this even if I need to shred my flesh and blood." Kai gently smiled before patting her head. "You don't need to feel pressured. There is no telling when you can find something like that. It can be ten years from now or you may never find it.

"But… What I know is, the chance is never zero as long as you keep chasing it. Committing suicide is just the way of a coward who only wants the easy way out. That's what I believe in." Kai finished his explanation with a smile.

Felice looked at Kai with a dumbfounded look before closing her eyes. Suddenly, a smile appeared on her face as she said, "That's a sweet story, Big Brother."

"Ahaha…" Kai scratched the back of his head, never intending to make it like that.

"I see. I may not be able to find it, but from Big Brother's story, I can still get that strength to go on." Felice smiled.

"Yes. You want to pay Roselyn back? Do it. At that time, you may find another thing you want to do. No matter how small it is, you can keep doing it. If you want to give a homeless person money, how about you teach him how to make money and give him shelter? By doing so, you can do good while spending more time in this boring world. Before you know it, you have many things you want to do to the point you need to start rushing many things. Your everyday life will start getting occupied." Kai smiled.

Felice gently nodded. "Listening to Big Brother eases my heart. You don't sugarcoat your words like other people who asked me to keep pushing forward without giving me the solution itself. Instead, you give me the positive and negative things I need to know and what to do in this situation."

"I just don't like giving an empty promise. Besides, I don't give you any solution… It's only my personal experiences."

"Actually, I feel like I want to do something."

"Oh?!"

"I want to be Big Brother's wife?"

"Hold up. What did you say?" Kai widened his eyes.

"Haha, I'm joking." She chuckled. "But it's true that I would like to do something for Big Brother. I feel like I will find something that I need in my life to keep me going forward. That's why you don't mind if I try hard to give you something back, right?"

"Well, I don't mind, but you shouldn't make my girls jealous, you know." Kai shook his head helplessly.

"I want to be a leading scientist. I want to decipher everything about Magic… Why do humans have Magic and why the Magical Beasts evolve due to this Magic. Maybe, at that time, Big Brother doesn't need to go to the battlefield anymore since I will solve the world's problems."

"That's quite a big goal you have there."

"That may sound like too big for a goal and it's idiotic… I don't even mind if Big Brother laughs at me. But—"

Before she finished, Kai already patted her head again, "I won't laugh at you. If you think you can do it, then do it. Do you think it's possible for me to become a General of the Army within one year? When they don't know about my achievement, they will believe it's not possible. But when I'm like this, it's just a matter of time, right? It's ridiculous but not laughable."

Felice smiled. "Then, I will probably start learning about Big Brother's Magic first. From my perspective, I could see that Big Brother's Magic is generated from science. Sound Levitation, Super Sonic Vibration, and other things… As expected from the Unorthodox S Rank Sound Magician."

Kai only laughed it off, but Felice stopped him with a serious expression. "But! I found that the Magic you used earlier was slightly different from science. In fact, you have just broken the Physics Law by creating an invisible track for the kids to swim around."

Kai's expression turned serious, never expecting someone could see through it, let alone someone who didn't know him. When he took another look at Felice, he felt that Felice might be able to do it. "So, what are your plans? I can give you a recommendation to anyone you want to meet, you know."

Felice looked down, contemplating for a minute before answering, "I have two people I would like to meet."

"Ho?!"

"The first one is your teacher. She is also a leading scientist despite the fact she is a General of the Army. I will make her my role model."

"Haha, that's a good role model you have." Kai couldn't contain his smile. He obviously felt happy when his teacher was recognized by others.

"Then, the second person… I don't know if I should say it…"

"Just tell me that person. Take it as I'm interested in you." Kai smiled.

"Is that so?" Felice hesitated for a few seconds before saying, "The S Rank Magician known as Poison Master."

Kai widened his eyes but still nodded his head. "I understand. I will tell someone to arrange it. Maybe after you learn many things from her, you can move to the US Base to meet my teacher. I will be waiting for you in the US Base."

"Yes!"

"That's right. One more thing. Since you want to decipher my magic, I will give you a reward if you manage to do it." Kai smiled.

"Really?"

"Yes."

"What is the reward?"

"The little truth behind what you called Magic and why no one manages to see through it until now." Kai smirked.
