Draco finished up his tasks in the Rank 7 Castle and exited to the real world.
Once out, he sent out some Sanguigno Brothers to acquire more NuSmoothies, and had even asked them to procure an extensive amount of supplies, before he went out to see what happened in his absence.
He quickly stumbled upon many places where the construction work had begun. They would expand the castle, allowing for many facilities to be built.
From the looks of it, it would probably take about a month for everything to be done.
Alas, this was the real world, so no matter how much money Draco threw at the problem, some things simply couldn't be accelerated without risking a badly done job.
Still, Draco was impressed by the progress so far and left everything to his people to manage.
