How long will it take for abs?

Someone who has bas please answer. Im 15 5'9 and 125 pounds. I workout my abs everyday just started like a week ago. I do 700 crunches different kinds. They target all the abs. I run track so thats my cardio. I can only see them after i workout then they go away. Should i do the crnches slow and less reps or just keep doing this. Thanks
