The Heaven-Defying Rampage System

[Shameless but with standards, an utterly satisfying power fantasy!] With the System in hand, the world is mine! Killing people one at a time? Slaying monsters one by one? Tch! Pathetic! If I’m going to kill, I’ll kill by the tens of thousands, by the millions! What? Isn’t it exhausting to kill that many by yourself? Tch! Are you stupid? Ever heard of teamwork? If you’re going to play, then play in a party! How many people? Just a dozen? Tch! Pathetic! If there are fewer than a hundred thousand, I’m not interested! What? You can’t stand me and want to beat me up? Fine! A group fight or a one-on-one? You choose. A group fight? That means me and a million Martial Emperor Realm underlings against you! One-on-one? That means you alone against me and my million Martial Emperor Realm underlings! Killing monsters levels me up, killing people levels me up, discovering planes levels me up, and subduing divine beasts levels me up. Damn! This System really is heaven-defying! Wahahaha! Just watch me crush my way through and blow up all the planes!
