Need your guys opinion!

So I started going to the gym about 4 months ago. I am 5'9 and now weigh between 165-170. I lost 31 pounds in those 4 months from cleaning up my diet completely and going to the gym 5 days a week. Now my question is how do I begin to have a shredded body? I have a pretty flat stomach but still no abs? My friend said I should start bulking then cut again to get abs but what do you guys think? Thanks for your time.
