The characters are the sister-controlled leader of the Demonic Shadow Sect and a bunch of subordinates controlled by the leader, a leader controlled by the leader.
The plot is a protracted war between the leader who controls the village and the leader who controls his subordinates.
There is such an equation in the hearts of the Central Plains martial arts people:
Shadow Leader = Beauty under the Moon
"The beauty under the moon is just my sword." The leader emphasized for the umpteenth time.
"That's right, we all know that." Demon Cult members.
