I am hesitating between three stars and four stars. After all, it was written in 2017. Looking at it now, some of the plots are a bit awkward and the writing is a bit flat. There are many plot points but the ending is very dull, but it is very satisfying and satisfying. There are not many villains with higher IQs. It's fine to read purely as a fun article. The characters of the two pairs of deputy CPs are more attractive to me, but it's a pity that I didn't write them in detail.
