He was only trying to figure out where her foot was hurt, to confirm if it was a sprain or a fracture so as to determine the best way to treat her injure. If she kept moving around like that and he didn't handle it properly, there was a risk of making the bone misalignment worse, which would cause her even more pain.
Looking at Xiaowan's swollen foot, Li An'an grimaced in sympathy, as if she could feel the pain herself.
Seeing Xiaowan not keeping still, Li An'an persuaded, "Xiaowan, stop talking and moving about, Chaoyang surely knows what he's doing. Isn't it true that the special forces on TV can do it all? How could he not be able to treat even this little injury of yours!"
Mu Xiangwan watched him, his technique seemed familiar. She asked timidly, half in doubt, "Do you really know how to do it?"
Su Chaoyang didn't respond to her question, He simply lifted her foot onto his knee. Kneeling on one knee by the car door, he continued to rub the most swollen part of her foot.
