Between heaven and earth, there is a demon sword called Qisha. There are seven killing gods sealed in the sword, which can kill heaven, earth, humans, gods, demons, Buddhas and demons respectively. In the past, the world's best sword god, Sword Po, practiced the Seven Killing Sword Technique in order to reach the strongest state of the sword. He was later corrupted by the magic sword and eventually committed suicide. After that, the sword was passed around and finally found its way into the hands of a blacksmith in a small mountain village. In order to unify the world, the Demon Sect wanted to free the seven killing gods from the Seven Killing Swords, so a mighty demon extermination operation began.
How sloppy.
