Xu Yang gave Sally two ice creams and then tested her magic power.
Ratmen and ordinary rats had a symbiotic relationship that made it easy to summon the nearby rats. Sally found a nest of rats scurrying around the industrial park and sent them to Rat Village, leaving one small white mouse for testing.
Xu Yang stuffed the small white mouse into an 8 cubic meter glass container, then, at Xu Yang's command, Sally pumped a massive amount of biological magic power into the small white mouse while simultaneously observing the changes the mouse underwent after receiving the magic power.
3 seconds: The size of the small white mouse noticeably swelled.
10 seconds: The muscles of the small white mouse significantly expanded, doubling in size, and the white fur became sparse, unable to cover the enlarged body.
