Okay, today I spent half of the day going through Ruth's displacement shader. What I understand is that ,if I'm not wrong, the displacement changes as the normals move by using a "If-Then-Block" node. But when I look into that node it was a large network and very complicated. With the current knowledge of material shaders I could not handle such complexity. But luckily there was Mr. Ron and he have a better method to achieve whatever I was achieving. And so he created a displacement shader with noise in less than a minute. He explained what each node does.

By linking the surface position of the Global Variables to the displacement along normals I am able to have what ever displacement shape I want depending on the noise pattern.
This is done by using turbulent noise.
He also fix my shader so that the opacity control will be serperated from the color ramp.
