Synopsis

The protagonist, feeling unprepared for the Academy of Demonic Arts, uses a nano-machine to scan Guard Jang's dagger technique. The protagonist initially masters the technique in his mind, but experiences severe pain when trying to use it, as his muscles aren't trained. After adjustments and a painful two-hour transfer, he successfully integrates the muscle memory, while Guard Jang is left astonished by the footprints suggesting he has mastered the technique.
