When Xiaoyao brought Fu Ning back, Fu Ning was already unconscious.
Right before she passed out, Xiaoyao seemed to have heard her murmuring a few phrases like "she is not," "she is a bad person," "fake," and the like.
But Fu Ning wasn't clear.
The poison had invaded too deeply; even though Xiaoyao moved her immediately and administered the antidote as quickly as she could, the toxins had already spread throughout her internal organs.
Having been poisoned for too long, even Xiaoyao wasn't fully confident she could save her life.
It was just earlier that morning they had eaten breakfast together, and Xiaoyao had quite a good impression of her.
How did it happen that she suddenly became a wanted criminal of the Prince Residence, and the kind that is to be killed without negotiation?
Just now in the backyard, she had indeed heard Si Sha's men leaving to capture someone, saying something about... an execution order, to kill without discussion.
