Milton Cheney was taking notes on a small notebook.
[Magic symbols overlay experiment - 42nd attempt: Successfully overlaid three magic symbols, fluorite showed no abnormal reaction, overlay effect unknown.]
Seeing Milton stop writing, Morton didn't continue overlaying new magic symbols on this piece of fluorite, but put it aside.
Raw fluorite can only withstand an overlay of three magic symbols at most, any more would require a finished fluorite disk.
The reason for not directly using a fluorite disk for the experiment was straightforward - fluorite disks are pricier than fluorite.
Putting the fluorite aside, Morton picked up a fluorite disk and repeated the previous steps to overlay three magic symbols.
After the overlay was complete, Morton spurred his spiritual power, the fluorite disk flashed, transformed into a large fireball, and swiftly flew towards the distance, eventually exploding.
