I'm looking for something like super detective in the fictional world, reasonable power progression, decent protagonists, no racism.
What is it exactly that you enjoy about the novel? Maybe people that haven't read it might be able to recommend something to you as well!
Eh, haven't read that novel. Probably " Thriller Paradise " ? MC has super deductive skills. That's all I can say.
have you tried "the Lord of the Mysteries"? ain't mainly detective style but is has a lot of mystery, and if i remember correctly he disguise himself as a detective
I'm probably late here but I also recommend the above-mentioned ones with detective mystery. Lord of the Mysteries (1300 chapters completely translated, top recommendation) Thriller Paradise (500+ chapters translated, finished 1400 chapter raws, in my to-read) My House of Horrors (1000+ chapters translated, top recommendation)
