Others thought she had gone mad, but they didn't know that those two years were spent soaking up the experience of a titan to her heart's content. This wasn't a case of being tormented; it was clearly the teaching of an excellent mentor who didn't need to utter a single word. Through repeated thrashings, Dorothy's body had deeply internalized the Dragon Witch's combat skills.
In fact, by the end of the first year of those two years, Dorothy was barely able to fight back against the Mother Tyrannosaurus, and after a year and a half, she could maintain an undefeated record. As the two-year mark approached, she was even confident she could counter-kill with about a 70% certainty.
But Dorothy held back all of these achievements. She never fought back, instead taking the beatings without complaint, at most trying to dodge as much as possible. All of this was to extract as much as possible from her formidable Mother Tyrannosaurus teacher.
