where to go after first three bosses

[Desouled]

not sure where to go when i try to go anywhere i hit a green wall which seems like the end of the map.

Look closely at the statues at your spawn/base. They will provide the clues you need to bring down the wall.

[Tabryne]

If you've lowered the first wall and are hitting the indestructible green wall talk to the center statue a few times to find out which direction you should be searching in.

[SimranZenov]

what Tabryne said. If you've already lowered the first wall, then talk to the statue again
