Post the file here.  

...have to see the file, but maybe a void sweep pathed along the edge would clean it up.

i caouldnt attach since the file is too big,is there any other way i can share with you?

Is it splines or arcs?  Spline should be continuous and arcs should be tangential.

i just realised there are total 3 edges that are not flattened,the other is on the left side~

You need to smooth out those transition from one spline to another of the mass.

thank you but im not sure how to do that TT

Instead of trying to fix it, I would just redo it. Create the Solid and Void Mass Host from Surfaces of the two existing Masses, close out and use Roof by Face instead of Wall by Face.
