If you do this again for 7 days you get the rinne sharingan (only if you already got the rinnegan) show it to an animal for 7 hours and you will summon the ten tails. if you watch it for 7 minutes on 16 different devices then destroy your devices you get a susanno. if you watch this for 2 hours you learn the fire ball jutsu. watch this while doing your math worksheet and itachi will help you with your worksheet.
