The youth was named Lu Song, and he was Tai Yi's child.
After Tai Yi became the Heavenly Emperor, he had countless children and simply didn't have the time to look after them all.
He selected the ten children with the best innate potential and entrusted them to Bai Ze's tutelage.
Lu Song was the youngest of those ten, and Tai Yi doted on him immensely.
