The Art of Body Transformation, as an advanced course in transformation magic, was originally not open to underclassmen because the prerequisite for studying it was that a wizard must first master transformation magic.

Zheng Qing learning transformation magic was purely accidental.
When he first entered university as a freshman, his head ailment, which had been dormant for over ten years, suddenly reoccurred. The campus hospital and the school's experienced professors searched for the cause for a long time but found nothing. Ultimately, using the simplest and most straightforward method, they taught Zheng Qing the transformation magic that wizards use to evade disasters.
