At least, it was far less difficult than controlling two streams of Magic Power simultaneously.
To put it bluntly, it was like the difference between trying to walk by moving the arm and leg on the same side versus solving two advanced math problems simultaneously and at the exact same pace.
'Never mind trying or practicing it, this wasn't an idea a normal person should even have...'
Lin Mo's idea was actually a bit of a shortcut. He was splitting off from a circuit that was already running, rather than operating two different circuits from the start. This allowed him to leverage some of the casting momentum from the original circuit, making it comparatively simpler.
The latter, on the other hand, was true "Double Casting"—a concept that, for now, existed only in myths and legends and was widely considered impractical.
For him, at his current stage, it was practically impossible.
