Yao Ling wasn't stupid so she naturally understood what Xiao Fang meant. She also didn't want to be entangled with this woman but she didn't have a choice. However, she was still feeling thankful for Xiao Fang's care.
"Is she your real sister?" Yao Ling asked, trying to ask about the sister's identity. This was a better method than interrogating this woman with force --- saving her from the messy trouble.
"Yes, she's my real sister..." Ying Ying said in a low voice --- she told them the truth so far. If she wanted them to help, they needed to know her sister's condition first. If it wasn't because of this man's sudden disappearance, they wouldn't be in this predicament --- in a way, she wanted to get revenge as well!
"Tell me her crime first and I will think about whether I could help you or not..." Yao Ling said. "I don't know you and your background so it's justified for me to be a bit more careful, right?"
