Lei Fei's Cap of Life

I'm having trouble getting this item, I was just hoping someone could reassure me these are the EXACT steps to recieve it...

Ok, I set VSmode for 1 fight, like 12 seconds or whatever, and I keep using senshippo fully charged CONSESCUTIVELY for 8 rounds... I've tried doing that, and also tried doing 8 rounds while just using it once or twice but always fully charged...Ive fought at least 100 times trying to get this thing...

Can someone give me some advice...either way Im gonna keep trying to get it...oh yeah I know this is OLD and your all playing evolution right now =) I cant wait, thx for any help.... btw is this item even good looking? Cuz if its not I dont wanna keep trying to get it
