"All right, let's get started, Xuexue. Lend me your silver needles, I forgot to bring mine." Nangong Beiying didn't really forget to bring hers, she just figured that since Qin Xue ambushed her with the request, she might as well use Qin Xue's needles.
"Fine, use mine, here you go." Qin Xue knew Nangong Beiying was doing it on purpose, as a petty revenge for her unannounced plan, and she was fine with it.
Qin Xue handed Nangong Beiying the silver needles and then lit the alcohol lamp. The heat would be soothing for dealing with Ye Xiao's rheumatic leg, making the treatment more effective.
"Nangong Beiying, what are you putting on there, what's it for?" Ye Xuan asked curiously as he saw Nangong Beiying take out a packet of something and apply it onto the heated needle.
"Don't interrupt me." Nangong Beiying didn't have time to explain medical procedures to someone who knows nothing about it.
