不慌不忙 见识过风浪

玩命是日常 但我不怕伤

四两拨千斤 刺客却坚守正义

敌挡就杀敌 鸡挡就杀鸡

Translation:
I'm unhurried, I've experienced the wind and waves
Dicing with death everyday, but I'm not afraid of injury
Appearing coquettish for a second - the scissors have already been unsheathed
Countering your moves with my own dirty tricks, the target can't escape.
Accomplishing great feats with little clever moves, yet the assassin upholds justice
Kill the enemy if they get in the way, kill the chicken if it gets in the way
Kill the chicken, kill the chicken, kill the chicken
Flying blades, scissors, attack, prepare yourself
Assassin, assassin, assassin, scissors assassin
A master of performance, a thorough disguise
The customer's wish - entrust its fulfillment to me
A windy, moonlit night, my blood is restless
Hatred and prejudice have all been dissolved by me
