His hand was very light, but when it touched her foot, it hurt so much that she screamed. Xu Xiaochun buried his head deeply under her leg and blew on the injured area gently. The breath in her mouth was very warm, and it seemed to flow through the blood vessels in her legs and feet all the way to her heart and lungs, blowing straight into her heart and making her feel itchy, numb, and warm.
