The doctor was not optimistic about Ruth.
The main reason was because Ruth basically used up her entire mana and energy. Not to mention, what she used was a forbidden magic.
"Forbidden magic: Wind of life, arrow of destruction."
This was the magic that Ruth used, but no one knew for sure what kind of effect this magic actually has. Because Ruth didn't actually tell everyone all the magic that she had learned when she was in Afirer Kingdom.
It was normal.
And with Ruth's strength at that time, it was obvious that no one would dare to coerce Ruth to tell them the truth.
Who would dare?
They would end up being bombarded by Ruth's arrows to the point that there wouldn't be nothing left on their body.
Unless they wanted to provoke Ruth, no one sane would do something like this.
Though…
At the end, Ruth herself was the one who made the decision to fight and trade her own life to close the passage.
