In the end, although he was doubtful, Mu Di Bai was fairly insistent that he went and swept, so in the end after giving Mu Di Bai a strange look, Di Tou sighed and took out the Mandate broom before walking over to the side and taking a breath. Sinking into the two auras of 'Void' and 'Human' and then combining them, Di Tou took a breath before his whole demeanour changed and he began sweeping.
Once he began, he lost track of time, and all he could focus on was the soft strokes of his broom against the ground, and the delicate control of Void Qi that allowed the leaves, the grass, the dirt… all of it to fade away, revealing the soft stone and earth beneath, leaving the ground clean as if it had been untouched in a thousand yaers.
