I got this idea from a problem I have in real life. I ordered something before and it end up with someone stole it. It didn't arrived home (｡•́︿•̀｡).
This delivery system is actually from a far away country. It opened a branch in Andelf and it became quite popular since.
Mostly because it prevents from being steal by someone and arrive home safely and most important is faster delivery rate. This also applies to normal delivery.
The box that the man gave to Adam is a core that give NOVA the power supply and shape shifting to any kind of animal.
It still have more procedure before being deliver, for normal delivery. Which I will explain some other time in the novel.
