Whats the fastest way to get a six pack?

I am currently age 16 at 5’7 and 120 lbs very little to no body fat. I was wondering if anybody could give me a good ab workout routine. I understand that you have to have a good diet and I have no problems with caloric or protein intake. I was also wondering if I have to cut out fats and junk food and such, since it really doesn’t effect me due to a very high motabilism. I would really appreciate it if anybody could set me up with a really hardcore workout routine that includes sets, reps, which exercises, ect. I would really like incredibly ripped abs, so if anybody knows an incredibly effective workout routine, I would really appreciate it.
