The Void is an absolute darkness where even the concept of "darkness" does not exist, and it lacks the simple spatial concepts of length, width, and height. It's as if one cannot find a single natural number among all negative numbers, and no material can find a place to rest in this zone. Yet in fact, I brought my own body into it, into this darkness.
If you asked me to describe what this scene is like, I wouldn't know how to explain it. First of all, the Void is a domain beyond description with words, so I can only barely say that my body is hanging in the darkness.
You can feel your body constantly tending towards extinction, as if telling me "I shouldn't be here." However, by relying on the power of the Third Door, I can unreasonably resist this tendency. I imagine that when Shan Liangyi first ventured into the Post-mortem World, it was by the same method that he maintained his presence in the Void Domain.
