Li Xue looked at the old butler. No doubt she could feel the necessity of the situation just looking at his worried expression. Looking at him like that she could vouch on saying that he was someone really loyal to the royals, even though she has not even scratched the surface of his personality.
But at this moment, knowing him was not the desideratum rather was someone's life. For her, she was not considering her actions in the benefit of royals but the benefit of humanity. She was not saving the life of the King but the human who needs her blood to survive.
Her eyes went to look back at the man, knowing that she should at least ask him once. Not to prove his dominance over her but to respect the care and love he showers on her, without asking anything in return.
