Five points, it's a good read. I read less of the main text, but this one is still good to read. Although the emotional lines are similar, it's good to read and I didn't get into the small world of the entertainment industry.
Three points, the first world looks okay, but the second world is a bit inexplicable. I couldn't stand the third world. The protagonist's emotions came out of nowhere, and I couldn't stand the rest of it.
Four points. The setting is very good. The logic of applying the setting of immortality and alchemy to the interstellar novel is quite reasonable.
The description of the book is a bit sparse, and there aren't many emotional scenes. Overall, it's an enjoyable book.
