This Is Not My Problem, It's a Problem with the Keys

What would the nicknamed Excalibur look like? There may be rumors in the world, and there will be rumors in the outside world, but I think this sword is not an ordinary sword, but a super weapon. It can transform everything, and it can also transform itself, create a different self, create a different sword style, and the height and dimension of the sword are all different.
