As Quinlan cultivated the cold Yin Qi, he was already accustomed to the chilly air, so he didn't mind the cold winds brushing past his body as he carefully attached the plate to his back.
"And done!" After a little adjustment, the back plate finally stuck to his back, tracing his spine.

After fastening the straps, she moved to wear her robe once again.
