Yi Tingfeng listened to Gu Zhiqi's question, his eyebrows slightly raised as he looked back at her, "You don't know?"
Gu Zhiqi: "..."
Of course she knew, only...
Yi Tingfeng: "The Sound Skill Cultivation Heart Method was taught to us by you, have you forgotten?"
Gu Zhiqi: "..."
That's exactly what she had forgotten.
Seeing the expression on Gu Zhiqi's face, Yi Tingfeng also realized, "Look at me, I forgot you lost your memory."
With that, he lightly patted his own head.
"The Sound Skill was taught to us by you, and so was the healing through music." Yi Tingyu took Gu Zhiqi's hand and sat down on the sofa beside her, "As for where you learned it from..." she paused here, looked at Gu Zhiqi, and said with deep meaning, "We've always been very curious."
"So, where did you learn it, Little junior sister?" After Yi Tingyu finished speaking, Yi Tingfeng promptly asked as well.
Then, he fixed his gaze on Gu Zhiqi, wondering if he would get an answer from her.
