She ran out after her but she couldn't catch up with her and she didn't want to leave Huo Ying all by herself. She just couldn't understand where it all went wrong, she understood that she had spent more time with Huo Ying than she had spent with her sister but what she feels for Huo Ying are duty and friendship and what she feels for her own sister if far more than that but she didn't know how to explain to Huo Lian. She watched her sister's back until she was out of sight in the courtyard then she returned to the room, she pulled a chair close to Huo Ying bedside and watched her, her face that was very white before was now looking better although she had not gone back to her normal self.
If it was normal herbs that she used on Huo Ying, there is no way the herbs would have such quick effects but they were spiritual herbs and they only grow on cultivated land, this is why only the vitality sect would have it even after it has stopped growing for that year.
