"Patronus Charm?" Draco blinked. "This spell can be used like that too?"
Although he had already mastered the Patronus Charm, he did not know much about it, and for the time being, he had been unable to find any related books at home.
Cedric, Draco, and Harry all wore different expressions. Draco's face held more confusion, Cedric's eyes revealed a trace of curiosity, while Harry's expression was full of anticipation.
Draco's confusion was actually what Wizet needed more;
he hoped that the magical theories and research results he shared would be understood by more people;
whether it was submitting articles to Hogwarts Voice or taking part in all kinds of discussions and voicing his views during them, these were all important ways for him to achieve that goal.
"We can start with a few phenomena..." Wizet said. "Last school year was a good example..."
"At the start of last school year, when we boarded the train to Hogwarts, something happened—the Dementors searched the train, which then caused a disturbance."
He looked at Draco and asked, "Draco, when the Dementors entered the train and began searching each carriage, what did you feel?"

"There was biting cold everywhere, my body became stiff, and in my head... there were nothing but bad thoughts."

he had not had a very good summer holiday. He had originally thought he would have a wonderful time traveling around North America, but his father had unexpectedly been imprisoned. Back then, he had imagined all kinds of "worst-case scenarios";
when the Dementors searched the train, all those "worst-case scenarios" had surfaced and become even worse...
