There was such a legend spread in this world.
When the sword domain is first formed, it contains nine swords, which can turn the world upside down and kill gods and demons.
The nine swords appeared, the mountains and rivers were shattered, the heaven and the earth collapsed, and the world went crazy for it.
There is a saying that has been circulated so far: If the sword falls for nine days, you will become an immortal.
