The Prequel to No Shore

I originally planned to write a full-length novel to explain and summarize the universe, cultivation, and civilization from my perspective, but I didn't want to put down the new book and write the prequel just after I wrote the first few tens of thousands of words. The prequel is expected to be between 70,000 and 200,000 words, and will be connected to "The Sky". Because it is not a story and many of the contents will only appear in the second half of the book, I read this one alone. When writing the prequel, new books will not be updated. My writing idea is very simple. I only write one book at a time. Even if inspiration comes, I will write it down first and put it aside. I will not push two books at the same time. In fact, the main reason is that I am reluctant to explain in chapters why the world has changed, the system has changed, how to accept the changes that are too big, and why the protagonist is like this or that. This book tells two stories and is also an interpretation of "The Sky Without a Shore".
