If they don't inform her and left without a word, as a first degree realm practitioner, she would be equivalent to a fat sheep waiting to run into a pack of wolves in the Dark Moon Forest. There was no way she could leave this place alive.
No matter which method they chose would be life-threatening situation.
If it was normal times, no one would leave Huang Yueli on her own.
