[Silvena's POV]
Without turning his body, Orlan raised one hand.
Mana rearranged themselves into a glowing arc of script and figures, and in seconds, a full equation stretched across the manaboard behind him.
"I don't want to hear any excuses. If you wish to stay in this class…"
"Then, solve this."
A shimmering web of numbers and symbols began to spin across the manaboard.
The mathematical question appeared.
Silvena recognized the structure instantly. It was a refined equation built around high-level magic theory, specifically involving mana compression ratios and efficiency thresholds.
Even before the instructor had finished projecting the final variable, she could already see where the trap lay.
The equation required a working knowledge of advanced spellcasting infrastructure — how mana condensed under pressure, how its flow rate changed in elemental conditions, and how internal systems stabilized volatile currents during mid-cast transitions.
