Hensheng (恨生, Hènshēng) is Jin Guangyao's sword.
Hensheng is a flexible "soft sword" easily hidden on the user's person, usually wrapped around the waist or arm. Its blade, however, is extremely sharp. Once it has been wrapped around an object, its user can send spiritual power through the sword to cut that object into pieces.
A few famous swords were destroyed by Hensheng's special ability that allows it to cut the object it is wrapped around into pieces.
