A pair of bracelets that have the power to make peace between two people for a year. If one of the wearers is in trouble, the other one will know when the bracelet loses its power. It will also lose power if the wearers' tendency to each other turns to pure love. The bracelets have a gem on the center, one black and one white. The items are destroyed when Han turns into Stone-Hearted Assassin (石心殺手) and splits it in two, thus caused the other bracelet to break along, however, the disappearance of Xiu's bracelet may refer to him having fallen in love with Han.
