Over the past ten years of reading history, I still have an impression. The types are relatively mixed, and some were written earlier and may not necessarily meet the current taste. I am just sharing them and will add them later.
It feels like the one that depicts Sherlock Holmes the most closely to the original work among the fanfics I have read. The heroine is also very interesting, the plot is reasonable, and the emotional pull is well written.
This author has written a series of three books. I personally like the first one better, which is called Life of Making Money. It has gotten better and better starting from the chapter on "Dai Cheng Si Fu Jin". However, it may be because the author has a special background and age, so it is now closed and cannot be read. Those who are interested can collect pirated copies.
