During the AC essay competition, I wrote nearly 10,000 words in one day like a burst, and then became inert again. There are some non-mainline "allusions" in this article, such as Detective A's "treat without paying the bill" personality and Mr. Fan's "extraordinary" reputation, both of which come from the "crystal of the wisdom of many people" in the original area of the AC forum. Therefore, readers who accidentally clicked in, please read this article with a relaxed and not too serious eye. If you are surprised by the decryption chapter and motivation, please do not search for the author. Above.
