On the top of Cangshan Mountain, in the abyss of the sea of ​​clouds, stands a solitary tower called "Sword Pavilion". No gold or silver is hidden here, no mortals are accepted, only famous swords in the world are accepted. Whenever a sword is born from a weapon, no matter how far it is, it will eventually turn into a stream of light, fly back here, carry the master's cause and effect, and turn into a low cry in the pavilion. The sword guard is the only listener of these thousands of causes and effects.
