A Taoist priest accidentally gained the ability to travel through time uncontrollably when his sect encountered an invasion of alien species. He was forced to jump back and forth in the broken timeline, watching the people closest to him disappear and forget himself one by one. In the course of time-travel and pursuit, he gradually discovered that time-travel is no accident. There is some deep connection between alien invasion and the disruption of the timeline - and he himself may be the key to it all.
