How to get gas from the MJ Quiz Event

1. Enter Zombie High and copy your unique account number. 2. Go to the Zombie High cafe, navigate to the notice, paste your number in the MJ Quiz Event, and enter the answer. (This quiz's answer: 상처에솔) 3. Re-enter Zombie High and check if your reward has been received. (They do this every month, but it's a bit late this time. Maybe because of Eunha and other things?)
