In midair, a transparent disc-shaped mechanical device was slowly rotating.
In Kane's eyes, the device was covered by two enclosed caps on the top and bottom, with a circle of sharp teeth exposed along the edges.
This circle of teeth could spin with Kane's output of magic power for cutting.
By expending magic power, this device could hover within a 2-meter radius around Kane.
This was the most basic mechanical device, the cutting disc, mentioned in this book.
Kane took out an old friend of ours, a piece of log, from his space equipment.
He placed the log on the desk and controlled the cutting disc. With Kane's control, the teeth of the cutting disc spun rapidly.
The cutting disc slowly met the log vertically, and wood chips instantly sprayed out, cutting an incision immediately.
Looking at the cut on the log, Kane was rather satisfied, as controlling this mechanical device required very little magic power, entirely within his tolerance range.
