I really wish this novel chronologically takes place before the events of the other novels in the vast expanse and exists in the epoch where the vast majority of the vast expanse Dao domain was mysteriously destroyed, leaving only the misty vast expanse starry sky where all the stories except AWE took place.
I really want to know who was the cultivator that created the misty vast expanse and all in it, his ties to the person in the coffin. Was it Extermination? (It was hinted when he said chu yuyan situation was familiar), or was it patriarch vast expanse? (I assume it isn't him since the misty vast expanse didn't exist in his epoch and the starry sky didn't seem to be destroyed yet).
What led to the destruction of the dao domain? All I know is that It was hinted in AWE that there were traces of endless dao domain participation and extermination was also involved in more ways than one
