The Material Realm and Void Realm don't actually occupy the same space; their relationship is somewhat akin to the ground and sky, with a few connection channels interspersed.
These channels are mostly used by the Heavenly Demons of the Void Realm. Rarely does anyone from the Material Realm actively venture into the Void Realm.
Heavenly Demons are entities of consciousness, akin to the souls of beings in the Material Realm. Yet when they infiltrate the Material Realm, they are not easily detected. Conversely, when beings from the Material Realm enter the Void Realm, they must abandon their physical bodies and can only venture in as souls. Souls from the Material Realm are delectable treats for Heavenly Demons and can be sensed from afar, making them easily exposed.
With the help of Chaos Light, Guding Pirate Group arrived at the region of a connection channel after more than two months.
