After signing the contract, both Du You and the academy began their preparations. The academy didn't reveal the news to its students temporarily, for the students' organizational and disciplinary capabilities were far from those of the military.
If the students were informed, who knows whether the information would be leaked or not. Even in the Other World, this could not be guaranteed.
Moreover, it was certain that people from other academies would find out if the news leaked. By then, no one knew whether other academies would come to cause trouble, especially since it was a yet-to-be-exposed territory and was only at tier three.
With the Heritage Hall blueprints provided by the academy, Du You flew towards his own territory. The academy mobilized and sent the blueprints with exceptional speed, taking less than half an hour of this world's time to deliver them from the academy. This showed the profound resources of Capital University were indeed unimaginable.
