The End of the World: All Fear Comes from Insufficient Firepower

(Mudslide gameplay, single female protagonist, idealistic science, full-level ability award, semi-invincible, non-system flow, absolute fire suppression, blood bank plus one, non-Mother) Brother, do you know why you feel scared when you are alone in the apocalypse? That's because... Your firepower is not enough! You don't even have the blue fire Gatling, how dare you go out to fight zombies? Wait for my beautiful teacher, I will come with you soon... Ah, come and save you. … One morning, a young man who was seeking death in a parallel world lifted the quilt. "What a day full of energy, ah——" (This book is a bit nonsensical, with a strange style, the kind that makes you feel uncomfortable if you don't seek death. What about the content... Brainless happiness is over. This is an apocalyptic book, brother, who needs to use their brains to read a book?!) (The early plot is a little slow, don't mind)
