"There are many different ways a wizard can achieve the transformation of life forms."
"Transformation potions, transformation spells, transformation talismans, and so forth... these methods all lead to the same goal, but even with the same transformation spell, different wizards have different results."
"Powerful wizards can completely transform into another life form, such as Mr. Zhang in the Book Mountain Library... while the vast majority of ordinary wizards, after transforming, will always unnaturally reveal this or that characteristic."
"Like those who wear black glasses, the transformation will leave a circle of black patterns around the eyes; the ones with overweight body shapes, after transformation, still show an unusual posture... "
Stopping his explanation here, Professor Yi posed a question to Zheng Qing:
"Do you know the Impossible Triangle rule?"
