Zhongli's cubes are deliberate, it's not just a quirk.
Was commonly theorized to be square like the Geo Oculi because of the "solid" and "sharp" nature of the elements.
It's not, Zhongli continues to have the only square oculus, and the Liyue the only square vision (Monowheels are also circular, Linchpins that are not circular relate to the third descender)
