Preparing for a plane war involved a great many complicated matters, but the most important of them was registration.
Benjamin was not encountering plane wars for the first time.
At Noren Academy, every five years, whenever a class of apprentices graduated, Noren Academy would arrange for them to head to planes that needed to be conquered.
At the time, this appeared to be a "trial" for the graduates, but in truth, it was also a benefit provided by the Academy.
Basically, every selected plane was enough for a batch of Academy graduates to fulfill their military service requirements.
Wizards from the Combat Department generally handled the early-stage invasion and development, charging into battle, clearing a path, and investigating the plane's major circumstances.
Wizards from the Logistics Department, meanwhile, handled the mid-stage siege warfare, clearing out the most troublesome enemies, assisting in the establishment of strongholds, as well as the later cleanup and reorganization of the plane.
When they occasionally encountered a particularly thorny plane, a single plane could even serve as "teaching material" for two classes of graduates, providing long-term training opportunities.
However, once this Academy-provided "benefit period"—that was, their military service obligation—ended, it was not so easy for ordinary wizards to participate in the war.
That was because these planes used for expansion were spatial coordinates that high-level wizards had found only after painstaking efforts, enormous expenditures, and even risking their lives.
They were the core strategic resources of every wizard faction. Naturally, they could not simply be taken out and opened to ordinary wizards at will.
Benjamin's situation was somewhat special.
Under normal circumstances, even if the plane used as graduation "teaching material" had been conquered relatively smoothly, after five years of preparation, new graduates could still return to the previous plane to "work."
After all, even if
