Doomsday Sign-In System

Hao Nan activated the sign-in system at the beginning of the apocalypse. As long as you sign in every day, you will gain something. If you sign in continuously, you will receive generous rewards. There is only one condition for signing in... That is to survive! After the end of the world began, a mysterious forum APP appeared, which did not require the Internet and could even charge your mobile phone. You could communicate (zhuang) (bi) with survivors around the world anytime, anywhere. Hao Nan also lived a life of living in the apocalypse while browsing forums.
