Ninja Saga-ATM EXP [July 2011 100% work]]
here's the tutorial
- You can just go to the "Headquarters" and choose "EXP BANK"
- Enter level you need, then click "Start"
- Wait until the process was really complete (every 16 seconds the EXP will increase)
- If you are level 40 but have not passed the Jounin exam, then you can click on "Rank Up", then automatically direct you pass (do not forget it's gone on refresh)
