Li Caiyi would be lying if she said she wasn't. It was never a bad thing to have more information. 

"I hate to rain on your parade, but unfortunately, the chance of you getting any information regarding your sister's cure is close to zero. If it was that easy, then Kong and I wouldn't be in this situation."
