Originally, I was going to write a hastily ending, which was a comfort to myself, but since it collapsed, there was no need to be reluctant, and the reasons for the collapse were summarized: 1. There are no highlights and no selling points; 2. The logic is not rigorous, and the plot design is not good; 3. The style of writing is also a weakness; it is not that a certain feather does not insist and gives up, but a miserable achievement, which makes a certain feather "swing a knife".

Or that sentence: life is endless, pen farming, a certain feather will come back! hereby announced, thank you for the silent support of a certain feather, sorry, let you down!
