Compass Carburettor gave the leaders a basic tour of the place, only showing them facilities that needed to be shown.
Facilities such as the living area of the Double-Faced Monkeys weren't even spoken about.
Of course, none of them asked anything about it. After all, they weren't aware of its existence in the first place.
There was so much to show in the place that he spent an entire day and only showed a tenth of the facilities. Even though most of the facilities were empty, the basic structure required for the setup was already completed.
The only thing that needed to be done was to fill up the place with the required items.
And of course, who else would do that other than the leaders here? This was also why he showed them everything.
