Y'know what I just realized? The implications of Mu Qing, Feng Xin, and Lang Qianqiu being able to just use random dice to follow(or try to follow) Hua Cheng and Xie Lian. What that means is that it's not the dice itself that are responsible for transporting the user. Rather, it seems like once Hua Cheng has connected to a location using his dice, any dice can be used to access the path created. So rather than the dice being transportation arrays, it's rather that the dice project a transportation array of some sort onto a target, which can then be utilized by others afterwards. like using a printing press rather than hand-writing something.

huh. i wonder if Hua Cheng can even draw a transportation array.
