Before leaving Hogwarts, Murphy inspected the school's teaching situation. More specifically, he wanted to see whether the practical classes had continued according to his original plans.
The results were not bad. A former Oxford professor who had received the werewolf virus was in charge of teaching the practical classes. Murphy sat in for a while and found the man broad-minded and patient, perfectly suited to guiding these students who had only just begun learning scientific methodology.
Murphy was reassured.
Once these students reached their fifth or sixth year and had received sufficient training in scientific research methods, they could be sent to places like the Magic Research Institute for internships—doing unpaid labor.
After returning to the Magic Research Institute, Murphy worked with several teams to establish a magical power radar scanning model.
Calculations showed that as long as a massive directional magical power antenna array was used for frequency modulation, the magical power radar could achieve a scanning range of three to five thousand kilometers while maintaining an accuracy of one to two meters. If the accuracy requirements were relaxed, its scanning range could be expanded even further.
However, such a magical power radar could no longer be implemented with the Raven Array Antenna. It required greater array precision and far more computing power. Unless Murphy was prepared to use everyone in the mental network as human computers, the Raven Array Antenna could not remain active long enough to complete a full-angle scan.
Physically constructing a real magical power radar was imperative.
Fortunately, the various prerequisite magical technologies for the magical power radar were already mostly in place: magical antenna theory, magical power frequency modulation, magical metals, and so on.
The most important were magical metals and magical power-reflective materials. One would conduct magical power, while the other would reflect
