As a person that is previously part of a developed society and also a person that read fantasy novels, Rezen has some theories in his mind but if any of them was correct then that is something that he could not say to anyone. It was better to keep his silence and act as if he doesn't know anything
Rezen took some time to ensure that Treen wouldn't say anything to anyone as they waited for the flying ship to land
They returned to the deck of the ship to observe the place that will become their new home
Rezen doesn't know how big the City of Hope but even his eyes couldn't even see the end of the city
As the Savage Beast Realm is way bigger than the Earth Realm, a city here in the former might have a size equivalent to an entire country of the latter
This means that there are definitely at least millions of people living in the City of Hope and the number might even reach hundreds of millions
