Did you take the wrong medicine?

Lu Xifu read the sentence that she had highlighted and simply shrugged. And that made Yun Meiyi purse her lips. 

"And what does that shrug mean?" She questioned, putting her hands on her hips. 

Lu Xifu replied, "I don't know. I might not have." 

"How can you not know? Though not sure, right at the moment, this seems the core of the cure." She said and then turned back to the board and spoke again, "It says that your redemption will appear on the day when you will prove your rightfulness to him to receive one. So, think again and tell me, have you received one? Did you prove yourself?" 

"Do I need to prove myself to anyone?" 

Yun Meiyi nodded. "Yes, you should. That's what he has said while blessing you with the chance of redemption. Your cure will appear only after you prove yourself to him."
