"Good morning, everyone. I am the new professor of Arcane Mathematics here at Yiyeta Magic Academy, and you can call me Lynn..."
Under the gaze of the apprentices, some surprised and others skeptical, Lynn stood at the lectern, using his hand as a pen and pure magic power as ink, writing his name in the air.
The quiet classroom immediately became noisy.
"Professor Lynn, I heard you came from beyond the Mist Sea. Can you tell us what it's like out there?"
"Professor Philip said you believe this continent is spherical, so why don't the people underneath fall off?"
...
Perhaps because Lynn looked quite young, not much older than they were, the Wizard Apprentices did not show the reserve they might have in front of other professors and chattered away with various questions.
They asked how he crossed the Mist Sea, defeated the great whirlpool, what kind of magic he used to destroy half a coastal city, and even mentioned his free-fall experiments.
