Xiao was an Adeptus, a superior Yaksha. He had fought many wars, and was a tool for destruction upon enemys to Liyue and Morax.

He was felt as he was a machine, programed to kill. He did not have time for mortal affairs or activity's, seeing it as a waste of time as the evil seeped in. He never cared for any silly kinds of emotions, he always had his usual stoic act. Yet, strangely.. he could feel someone stalking him, which was... different for him? Why would someone be stalking him? There's nothing interesting about himself right?

He had never seen the person, but he always saw a shadow out of the corner of his eye and he was tired with it, irritated.

One day while he was on a mountain cliff, looking out to the view of Liyue. He was furious. Whoever was stalking him was absolutely incompetent, because Xiao could hear all their movements! He unhooked his spear and in a flash of a light.. he threw it back behind him. He heard a small yelp, and he turned around to see his stalker.
