From Chai Xin's words, Lu Xi'an and Yao Wei deduced that this girl should have more than one "nesting place."
A wise rabbit has three burrows. For a little girl to be alone in this world is already a difficult thing. To survive, finding several hiding places is only sensible.
Lu Xi'an asked Chai Xin what good things she was referring to, but Chai Xin remained mysterious and didn't answer, only saying that Lu Xi'an would know when the time came.
It seemed that it was indeed something Chai Xin was proud of; she even played coy about it.
After some time, Chai Xin started trembling all over, looking very unwell.
Lu Xi'an asked her what was wrong, and she just shook her head, saying, "I don't know, I just feel incredibly anxious."
"You're hungry."
Lu Xi'an quickly deduced.
Yao Wei also figured it out; both she and Lu Xi'an had experienced this before. She stared at Chai Xin intently, her expression not very pleasant.
"Are you trying to scam us for food?"
