Shui Bian is a man living in New Ashos. He is encountered outside a house whose resident is holed up inside. Tailers surround the home but are fenced in and Shui refuses to open the gate unless the player agrees to a bet. In exchange for 10 aura he will open the gate and if they player can kill all the monsters in the given time he will award them 2,000 auras.
If the player fails to do so Shui Bian will refuse to let them out until all the monsters are dead at which point the player will bully him into opening the house door.
"There... there all dead!" -Shui Bian
"Please tell me your talking about the people and not the monsters." -The Player
"Uh... which would you prefer?" -Shui Bian
