The Dean's office was already in a state of disarray, and Lynn hurriedly stopped supplying Magic Power, causing the storm to collapse immediately and the fine iron sand to fall onto the floor, making a series of 'clatter' 'clatter' noises.
"The Magic Power consumed is about 6 units!" Lynn sensed the reserve of Magic Power within him and immediately concluded.
This was the case when iron elements were readily available, but if relying entirely on Magic Mimicry, it would probably consume over thirty units of Magic Power, which is a relatively standard consumption for a fourth-level spell.
That meant with his current status as a third-level Wizard, in the best state, he could only cast three fourth-level spells, and that was with some of the computing power and Magic Power consumption being handled by the smart brain.
