How to create empty normal map?

I want to create an empty normal map , how do i do it ? The reason is because i want to paint multiple other normal map into the empty normal map .

I don't really understand how normal map works so i don't have any idea on how to create empty normal map.

Head over to the Texture Paint workspace, click the little plus sign + in the Draw properties on the right side (Properties Editor) and select Normal:

This way the new normal map also gets connected to the shader, automatically. The suggested RGB values are 0.5, 0.5, 1.0, 1.0 or #8080FF.
