While he didn't fully heal himself, it was enough for him to use his powers without being affected too much.
There were still some minor injuries that he hadn't healed, but he didn't keep healing himself since he knew that there was no point.
This place itself was dangerous, so it wouldn't do him well to remain in this place for long since he didn't know how it would change.
It was better for him to take advantage of the fact that he could move to get out of here as soon as possible instead of waiting here any longer.

When he reached it, he found that it was a very short passage that he could see the end of.
The end of the passage wasn't brightly lit, but he could still see through the exit to see what was behind it.
