It is the sharp edge tempered in desperate situations, born in the tempering of burning fire and broken bones, and carries the will of Nirvana and rebirth. The exquisite design of seamless switching between dual forms combines the fierceness of melee combat and the precision of long-range combat. Each swing carries the power of breaking and standing again. Each cold light is engraved with a legend reborn from the ashes. It cuts through the darkness with an immortal appearance and becomes the ultimate blade that controls victory or defeat.
