What is the fastest and best method to get the 6 pack abs?

Hello, I'm planning to work hard to get the 6 pack abs that I've always wanted to get. Thus, I'll need your help to tell me exactly what to do.

I'm usually someone that work out like 3 times per week in order to remain in good shape. Indeed, I workout my shoulders, chests, triceps, biceps, back, and legs however I rarely to not at all workout my abs.

Age : 21 years old

Fat : 27.6%
Muscle : 37.1%
Weight: 69.8 kg
Height: 173 cm

Hoping that you could provide me some guidance in what to do.

Best regards.
