The sword of the Jade Emperor himself. A simple katana and matching sheath, neither with any embellishments or additions. This mighty blade possesses no innate power, save its limitless cutting edge. A single, lazy slash was able to slice all of South Korea in half and the blade was also able to destroy the cloned Ruyi Jingu Bang. It can summon gigantic waves of incredibly hot flame at the user’s command and even the sheath of the blade is powerful enough to split in half the super massive swords wielded by Nephilim without any action on the user’s behalf. Even if somehow broken, a feat only accomplished once by the Monkey King using over a hundred National Treasures and multiple Charyeok at once, the blade will be replenished to pristine condition within minutes.
