[Flash]!
Using her most powerful skill with a lengthy 12-hour cooldown so casually showed that Feather Song was truly incensed and determined to teach Motan an unforgettable lesson!
However, her decision not to prep with [Dancing Petals] (floats for 1 second, and the next sly active skill's damage is increased by 100%) to amplify the damage of [Flash Shadow Traces] hinted that Feather Song still had no intent to kill Motan. Otherwise, with some luck, the back attack plus critical hit and damage increase of 100% from [Flash] might actually be able to instantly take out a player with weaker defensive power.
However...
When [Flash Shadow Traces], used as an opening move, hit Motan from behind, he was directly shattered into a burst of white light, dissipating into the air in fragments.
"Eh?!"
Feather Song, who at first startled thinking she had accidentally killed her opponent, then felt the sting of a short blade slicing across her waist from her side.
