Burial Sword Immortality

Above the nine heavens, there is the "immortal killing platform" hanging in the air, which is dedicated to killing swordsmen in the world. Thousands of years ago, the founder of the swordsmanship tried to cut off the way of heaven in order to seek immortality. As a result, he caused heaven's punishment and the swordsmanship collapsed. In today's world, sword cultivators are regarded as "those who defy heaven", and everyone will punish them if they find them. Only by burying the sword can one survive.
