The young guard called Teng song said in an unconvinced manner.

"Young lady, you said you're a weapon refinement master. May I know what your name is, which weapon refinement master you're studying from, and do you have any token to prove your identity?" Teng Yun said to Ling Chuxi after hesitating for a moment.
