Under Lynn's explanation, the assembled wizards finally realized what was happening, staring at the constantly rotating gear with faces full of horror.
This gear actually blocked all the light elements trying to pass through the gaps, without exception!
"This isn't magic!" Yasosi and the others exclaimed in disbelief.
The occurrence of such an eerie phenomenon directly proved that the speed of light was not infinite! Otherwise, each ray of light passing through the gaps would have instantly returned, and it would have been impossible for them to be blocked...
"It's feasible, this method is really feasible!" Glenn muttered to himself.
Just as Lynn had said, they had already succeeded half the way; now, they just needed to continue increasing the speed, and the returning light would gradually move backward, surpassing the blocking gears, and reaching the next gap!
"What is the current rotational speed?" Rafael asked eagerly.
