Tried to extend wall to the sloped slab, got visually trimmed wall.

I am new to Bonsai + Blender. I tried to model a room with a sloped wall attached to the slopped slab, I tried shift+E but there is a gap between the slab and the wall. Then I tried to extend the wall to the cursor, through the slab, around 7 meters high. Then there is a gap in the mid!
dle of the wall, with a shape of the slab. I guess it is the representation of the slab, that is visually trimming the wall. How can I fix this so that the wall is attached to the slab? Thank you.
