[xu-] Professor X is in the [2] middle of the [-(e)n] infirmary, seeing sick patients. He gathers them into 旬 groups of ten and gives each group a 勹 container, which they in turn open. The 勹 container contains a miniature 日 sun that floats out, covering the patients with a healing light that cures them only if it's a 旬 group of ten. Hopefully each group is, in fact, a 旬 group of ten.
