Situ Qinghuan's emotions were in a state of excitement, and when she saw her master suddenly knock Lu Chuan down and then take off the other's shoes and socks, her mind was a bit muddled.
When she saw the three black moles on the sole of Lu Chuan's foot, her expression changed to one of astonishment, then turned to shock, and finally to disbelief. Then she ran over strangely, crouched down, and grabbed Lu Chuan's foot, muttering to herself, "This... This can't be possible!"
The three moles on the sole of Lu Chuan's foot were very similar to those on Brother Deer's foot in her memory, in both location and shape. The only difference was their size.
Back when she and Brother Deer huddled together under a bridge for warmth, because she had lost her shoes and her feet were freezing cold, Brother Deer gave her his shoes to wear. They didn't fit, but they protected her from the cold's assault, yet Brother Deer's feet ended up covered with frostbite.
