Get the Troll System Through Time Travel

After traveling through a different world, activate the Keyboard Warrior system and bind a powerful artifact. As long as you can make people angry, you can gain anger points and redeem rewards from the system. The angrier the other party is, the richer the rewards will be. If you have murderous intentions, then wish yourself good luck. There is a premise: you cannot gain anger points by attacking people who are weaker than you.
