After sorting out a few things with them, they began telling about Roselyn's past.

The middle-aged woman could only sigh when she recalled everything she went through, feeling ashamed of herself. "That girl… is a strong girl… She has been fighting for this orphanage since young. Even when the kids here were bullied, she would protect them. These two are the examples.

"We once had a financial problem back then and could barely afford to eat. The girl didn't eat during that problem and tried to take on a job to get money for the kids. After finally, she started working for Union and climbed through the ranks in public school.

"She kept fighting in the frontline, wrestling with her life just to make sure the kids can happily live here. Haiz, I always wanted the girl to prioritize herself from time to time, but…" The middle-aged woman didn't continue and let out a long sigh.

Kai didn't reply to her for a moment before smiling, "I believe the kids also know about it since they respect her so much."

"Yes, indeed. A few kids took the initiative to ask me what happened and I told them everything. I wouldn't dare to take credit or lie to them about this, so they knew that Roselyn had done so much for them even if she didn't want to take the credit."

Kai nodded and informed them. "Actually, the same girl has received the promotion to S Rank Magician."

"!!!" Both the middle-aged woman and Sonia opened their eyes wide, looking at Kai. "You…"

"I won't lie about something this important." Kai shook his head, erasing all their doubts.

However, Felice managed to understand the entire situation in an instant as she opened her mouth while her eyes remained closed. "Everything is related to Big Brother. Big Sister's promotion won't happen anytime soon, so the only reason for her promotion is the mission that took her three months of her time.

"From how you visited us together with Big Sister, you must be together with her this whole time to the point Big Sister told you about this orphanage. The fact that Big Brother is famous for your strength while getting surrounded by mysteries… Or at least, that's why the news keeps spreading a bit of information at the time, making it hard for us to understand you completely while forcing us to idolize you.

"In other words, the mission that took three months to finish has changed her life completely, turning her into an S Rank Magician, which I don't know how… For the time being, with how Big Brother portrayed Big Sister, she seemed to have gotten far stronger than her previous strength and everything happened in a mere three months.

"After calculating a few more variables, Big Brother must be related to this promotion," Felice explained while still comfortably laying down on Kai's lap.

All four of them were stunned, including Kai. He never thought Felice would be this smart. Everything was pinpoint.

"You are good…" Kai smiled and stroked her hair again.

Felice only smiled and cozily enjoyed his hand.

"Want to go back with me to the US Base?" Kai smirked.

"As your wife?"

"Haha, you should grow up first before even thinking about it." Kai gently flicked her forehead.

"I have a great business for Big Brother. If you get Big Sister now, you will receive me as a bonus."

"I'm here for a mission, not to search for a wife. I've got my hands full, you know." Kai shook his head helplessly.

"Ah, that means I can't enjoy this lap again."

"Haha, you are not lazy… You just think too fast to the point you feel the world is revolving so slowly. That's why you're bored." Kai flicked her head again before raising his vision, finding a few people coming inside.

"Ah! It's true. They are here!" One of the kids shouted, alarming all the kids that he brought inside. They all looked at Kai with great curiosity as Kai fully knew that the two kids that tried to attack him in the front yard had told them about his existence.

The kids entered and ran toward Kai.

"Big Brother!"

"Big Brother, are you Big Sister's man?"

"We've heard it from—"

Roselyn finally entered the room and tried to mitigate the entire situation.

Kai only smiled since he couldn't answer them in French. Instead, he asked Sofia next to him.

After understanding what he wanted to say, Sofia opened her mouth. "He said he is not. He is coming here to play with all of you guys."

"Play with us?!" The kids opened their mouths in amazement and quickly grabbed Kai's hands, trying to drag him to the playground outside. "Let's go!"

"Mu…" Felice pouted when she felt the shake, knowing Kai would be taken away. She slightly got up to avoid falling over due to the sudden movement.

As soon as Kai rose from the couch, the kids pulled him to the backyard, where he could find many things such as slides and other things that would interest the kids.

There was a net above them, so the kids wouldn't feel that hot despite playing under the sun. Besides, it wasn't like it was that hot even during the day.

Meanwhile, Felice surprisingly dragged herself to the backyard and decided to sit in the corner, watching how everything unfolded.

Sofia, on the contrary, waited for them to come back as she began talking about a few things with the middle-aged woman and Sonia.

"Ah, I'm sorry for this display…" Roselyn quickly approached Kai with a bit red on her cheek.

Kai simply waved his hand with a smile, saying, "It's fine. You should enjoy yourself more."

After that, Roselyn was taken aback by Felice's appearance since she rarely would come out. And she didn't need to figure it out to know Kai was the one who brought her here since the latter had her eyes locked on Kai.

Before she could say something, a young boy suddenly approached Kai and tugged his sleeve. "Big Brother. Let's play! Does Big Brother know anything about any game?"

Kai thought for a moment before Felice, who surprisingly appeared next to Kai, said, "I will be translating your words."

Roselyn dropped her jaw to the ground, looking at Felice as if she was not the Felice she knew.

Listening to her words, Kai took that offer. "Sure. Thanks."

Kai thought for a moment before lifting the kid gently. "I can do this."

Felice quickly translated it, so the boy understood what Kai was saying.

A Magic Circle appeared below the boy's feet as he suddenly felt his body light due to something pushing him to the air.

"Don't move suddenly, okay?" Kai smiled. As soon as Felice translated it, Kai began loosening his grip, letting the boy floating in the air.

This was his Sound Levitation Magic and Kai had adjusted it slightly for kid use. "Now you can float."

"Wha—" The boy was surprised and tried to look down to check whether he was really floating or not. He then carefully moved his hands and feet, causing his body to shift a bit as if he was in a room without gravity. "This is interesting!"

The boy seemed to like it as he slowly adjusted his body, spinning his body around. "Hahahaha."

The laughter quickly picked the other children's attention when they saw their friend playing something different.

Another boy walked toward him and asked shyly, "Big Brother… Can I do it too?"

Kai simply smiled and lifted him up before creating another Magic Circle to levitate him. He told him to be careful too, which was translated by Felice. Since the tone and the words Felice said were the same, he believed Felice told everything Kai said, so there wouldn't be any translation mistake.

Looking at how happy these two were, Kai summoned more than ten magic circles at the same time, creating a certain track with his Sound Levitation. There were curves, slides, slopes, and so on, making it look like a small race circuit for a toy car.

Kai then connected the two to the circuit in succession, letting them float in the current like a fish following a sea current.

"Hahahaha!" The two kids couldn't stop laughing as they were having fun with this new stuff. They didn't know Kai couldn't do something like this a few months ago. So, this was the result of his training. He could control the direction of his Sound Wave at this level.

They could even spin their bodies around without accidentally leaving and falling to the ground.

Since the other kids were interested as well, Kai made a big magic circle that allowed them to stay afloat, allowing almost everyone to play in a kind of zero gravity room. Some also decided to play with the track.

Roselyn was worrying about their safety and watched over them anxiously, but she didn't ask Kai to stop because the kids were having fun with this. And it wasn't like Kai would be coming here again, so she just let them have this fun today.

Suddenly, one of the kids knocked on the other. The collision bounced one kid out of the Magic Circle.

Right after the kid fell off, Kai, with his super reflex, already appeared next to the kid and caught her gently, carrying her like a princess. "Are you alright?"

The kid was entranced for a few seconds before nodding her head repeatedly.

"That's good." Kai smiled and asked, "Do you want to continue playing?"

"Yes. It's fun, Big Brother."

Kai nodded and put her back above the Magic Circle so she could continue.

Seeing that action, Felice quickly threw herself toward the magic circle and floated for a few seconds before she purposely left and acted as if she fell off.

"Oh no." Felice tried to alarm Kai but ended up getting ignored and fell down with her face hitting the ground first. She thumped and pouted. "This is not working."
