The end of the world is coming, and the game starts with a mobile phone

The end of the world is coming. Lin Feng accidentally got a strange mobile phone before the end of the world. The system and functions on the phone seem to be incompatible with the end of the world. However, it is black technology after all, and it can be used barely.
Lin Feng: System, there is something wrong with your function! We said that they can stop time, so how come they can still move?
System: Host, please calm down. Humans are different from zombies. Time stop is only applicable to humans.
Raymond Lam: Damn, why didn’t you tell me earlier? I wasted points in vain.
