Game Apocalypse: My Family Are No Pushovers

Game + apocalypse + battles fought with brains + powerful background + factions + self-interest (putting yourself first) [It doesn't really take off until after Chapter 50. If you can't wait that long, don't waste your time here. Go find another good book!] Tired of reading about people on the bottom rung struggling to survive in the apocalypse? Come see what it's like to start from the top instead. The apocalypse is here. I can't keep enjoying my privileged life anymore. So I decided to hunt down the mastermind and beat him up. It's a distant goal, but I'm not worried. Because... My dad controls the entire Xia Kingdom military and has started playing a troop-spawning build, kicking off his middle-aged dragon-pride journey. My mom controls almost every research institute in the Xia Kingdom and has taken up mechanical calamities, embarking on her middle-aged phoenix-pride journey. My favorite big sister is playing the “ultimate support build”... and has awakened the final support technique: defeat all the enemies, and our side will be safe. Even my childhood friend and little sidekick has started playing an extreme damage build. She's unbeatable in a one-on-one fight! And me? I've turned into a bug in this world! The five of us form an organization and a five-person team, roaming around and “making trouble for the world.”
