A Book That I Personally Feel Is Pretty Good Recently

The first crime-solving novel is unsystematic, the frequency of cases is moderate, and the male protagonist's IQ is online. The second novel is about a protagonist who has a strong wife and a good physique every day. Personally, I feel that the third, eighth, and ninth books are all written by the same author. The system reward methods and skills are similar but the cases are different. I read the ninth book first, and the styles of these three books are not much different. The seventh book, Brother Da Ran, YYDS!
