Su Yu summoned them, asked them casually, and learned that their parents were all new humans from inside Black Iron City, previously engaged in the most laborious work. However, because they were chosen to serve him in the palace, the treatment of their parents would also improve. Upon hearing this, the four girls knelt down in fear, afraid that if Su Yu did not accept them, their families would return to their previous circumstances.
Su Yu sighed. He did not actually want any female servants attending to him, but seeing the tearful faces of the four girls kneeling on the ground, he couldn't refuse. He allowed them to stay, but he still attended to many things himself, such as bathing and changing clothes. He was indeed finding it hard to adapt to being served by others.
