Actually, a Magic Disk is a kind of 'one-time magic device'.
The magic symbols are inscribed into the Fluorite Disk, and once the Inscription is done, it becomes a Magic Disk.
The completed Magic Disk can cast the magic that is inscribed within it once.
The effect of this seems familiar, as if heard somewhere else before.
Milton Cheney had felt the same way when he first heard Morton explain this to him.
This is just like the 'Fulu' from the cultivation novels of his past life!
Engraving a Magic Disk can also be expressed as 'drawing symbols', and the Fluorite Disk may as well be 'Fulu paper'.
However, it was only when he began to study Inscription that Milton realized how difficult it really was.
Over the course of a month, the time Milton spent inscribing Magic Disks in the laboratory took up most of his daily hours.
Yet, it took him a full thirty-two days just to inscribe the simplest Magic Disk, which turned out to be subpar.
