Unsurprisingly, Sadie nodded and stated that she had no knowledge. "Sorry honey. I've never heard of them, even though I didn't know they existed."
Aiden was not surprised. Even more so than their mother, he knew that his sister had zero interaction with the opposite sex. So it was normal that she didn't know anything about such schools.
Aiden spoke in a calm voice. "You don't need to apologize, sis. Anyway, I also spoke to our mother and she said she didn't know much."
After Sadie said she understood, Aiden continued. "Since my unique skill seems to be linked to dual cultivation, I thought of joining such education centers. Of course, after discovered dungeons, developed my strength, and adapted to it."
Sadie nodded in agreement. "You should definitely do this, my dear. After all, your unique skill is part of your strength. The more you know about it, and the more you can find a way to improve it, the better for you."
