Although there are many readers in the comment area and social platforms who think the book is unfinished, as far as my reading experience is concerned, I don't think it is unfinished. At most, the ending is a little rushed, but the world view is still rounded out. This setting is really novel, and we still need to support the innovative works of veteran authors.
The first 80% of the reading experience was very good. I even directly subscribed and made friends. Although the second half of the development was suspected of being tortured for the sake of torture, it is not difficult to see the growth of the character in this plot. It was at this time that Ruanruan truly learned how to love others and discovered the pain caused by concealment and lies (the fall part), so it is reasonable. I give it four stars.
I am personally biased against million-word novels. In my opinion, such novels are able to write so many words only by piling up words and redundant plots to make up the number. But I finished watching Echoes and stayed up until the early hours of the morning every day. I was so sleepy that my eyelids felt sticky before I turned off my phone and went to sleep. It's very beautiful, and every foreshadowing is taken back. Once you finish it, you can't help but want to go back and look at the previous details. The best unlimited stream I have seen in 25 years.
