Defense Communication is a special communication tool developed by Happiness City.
It looks like a large mobile phone, with stable and extremely sturdy materials. It has some of the functions of a modern smartphone and can be used as defensive equipment in critical times, able to withstand impacts of around 400 joules three times consecutively.
And most importantly, Defense Communication is free!
Any resident who has been in Happiness City for over 60 days can register and collect it at a designated location.
Of course, the reason for such generosity is that once Defense Communication leaves the boundaries of Happiness City, it immediately becomes useless—not only can it not make calls, but all internal functions are locked.
Even communication between the Buffer Zone, Inner City, and Industrial Zone in Happiness City requires special permission, which is scarce and mainly allocated for public account communication.
