Ice Age Apocalypse: I Level Up by Causing Trouble

On Christmas Eve, my uncle, Garrett Wayne, takes a sip from the fancy whiskey I bought. Then, he points at me while grinning. "Well well well… I've been watching you since you were a kid, Flint. You were a bed-wetter when you were a little boy, and now that you're all grown up, you stay cooped in your parents' shop while running that social media account of yours. You don't have any skills at all. "My Ronnie, on the other hand, has an amazing job that will continue paying him and keeping him around no matter how hard times get. Small businesses like your family's will definitely crumble as soon as the tiniest change happens in the global economy!" All of my relatives roar in laughter at Garrett's quip. My cousin, Ronnie Wayne, pretends to be playing on his phone, though his grin has already become ear-splitting. Mom and Dad can only laugh along as well even though deep down they are very uneasy and anxious. I just gaze at Garrett coldly. In six hours, the blizzard apocalypse will descend onto this world. At the same time, a zombie outbreak will occur across the globe. In my previous life, Garrett, who had looked down on my family and me, didn't hesitate to push us into the upcoming zombie horde just to take over my parents' grocery store. In this lifetime, I swear that I will never let him off the hook! I'm about to pick up a plate of food and smash it onto Garrett's head when I hear a mechanical voice chiming in my head. "Ding! You have been bound with the Rage System! You may talk back and retort to others to your liking in exchange for supplies. The more arrogant you sound, the better supplies you'll receive!" As I look at Garrett's insufferable face, I let out a chuckle. "Oh yeah, I'm not skilled at all. But I suddenly remember this funny little thing. Uncle Garrett, you claimed that you had gone on a business trip to Brimstone eight years ago. But the truth is, you got arrested by the vice squad, right? "Does Aunt Cassia know about this?"
