This is a whole forum, if you don't know what it means, enter with caution.
Four volumes completed.
The general background of the story should be the main storyline that was cheated in "[Comprehensive] Dream within a Dream", and the last volume is from Wei Haolong's perspective. The narration should be the most complete, including the content that was not written in "[Comprehensive] Dream Within a Dream", so if you are interested or have the patience, you can go and take a look, there should be "surprises". As for the main chapter of "[Comprehensive] Dream within a Dream"... I revised it to the point of vomiting blood and gave up the struggle.
In addition, the first three volumes are supplements of some details. They can be read in conjunction with the fourth volume, or they can be independent chapters. That's it.
