Xia Xibei could have kept Qi Xin from knowing what she had done, but instead of doing that, she was very open about letting Qi Xin know: she just used her likeness to do something.
She had wanted Qi Xin to know that she had a different kind of ability.
This way, Qi Xin would definitely think of more messy things.
She liked to see Qi Xin overthinking.
The more she thought, the more she would confuse herself.
Ling Juan had escaped, and until now, Xia Xibei had not been able to find her whereabouts.
So, since they couldn't find her, let her appear on her own.
Xia Xibei thought that if Qi Xin really messed up, Ling Juan would definitely show up!
After all, Qi Xin was Ling Juan's own daughter.
Moreover, it was necessary to mess Qi Xin up so she would do something.
In the evening, Xia Xibei gave two bottles of medicine to Gu's father and mother, who came over on time.
