How to Collect Minerals (All Methods)

1. Reboot farming (Little time, lots of minerals) 2. Story farming (Lots of time, few minerals) 3. Buying minerals with gas from the shop (Huge loss) 4. Buying minerals with event currency (Just a waste of currency) 5. Minerals obtained from quests like Starry High, Elf High, Magic High, etc. (Not bad) Buying minerals by purchasing the Zombie High School comic books sold at offline bookstores or online malls (Delicious) Just do it like this.
