Du Heng felt the hand on his sleeve and turned to give Wu Shengnan a slight smile. He then walked over to the child, paying little attention to the child's cheerful grandmother.
From a distance, the child appeared to have a white layer on his skin, with flakes falling from his turned-up sleeves.
As Du Heng approached, he gently brushed his hand over the child's arm. Only then did he realize that it wasn't a single layer of flaking skin, but two, or even three layers.
Du Heng also checked the inside of the child's collar and found it was the same as the sleeves; his neck and chest were also entirely covered with this flaking skin.
Then he looked at the child's face, which was red, flushed, and scattered with some faint erythema.
Seeing this, Du Heng already had a diagnosis in mind.
