@leandro1amaral I have a feeling what he actually did was completely in line with everything else he has been doing so far, think of it like this:
The teleportation that he already had was unsafe because the travel causes interference with the magicules of the monster on long distance.
He already investigated the barrier that can block magicules interference because it was used n his town.
He has the ability to replicate magic (specially now that great sage evolved).
Result: He's probably just casting the magicule interference barrier on top of the troops while using teleportation on them as part of one spell, thus the travel poses no problem, theoretically. Fits in line with him saying it was a test run.
