Survival of Cannon Fodder in the Apocalypse

Fu Jin was a commoner before the end of the world, with a simple family, but she didn't expect that the end of the world would come and she would be so cruel all of a sudden. To put it simply, her boyfriend and her best friend were together, but she didn't know. To put it more artistically, it was that the two of them discovered their true love for each other, but she, Fu Jin, didn't know that she was the annoying supporting role and stumbling block, so she was naturally cannon fodder for Harmony. But, Fu Jin said that cannon fodder also has the right to live. It is better to die than to live. Besides, I have not seen the "happy" life of my ex-boyfriend and ex-best friend. How could I be cannon fodder so quickly? So in the end of the world, I have to find a way to survive. To put it simply, it is to watch how a newborn girl kicks out the scumbag, abuses her "best friend", and then leads her own big boss to live a post-apocalyptic life!
