Fantasy World: I Can Deduce All Things

I don't really like it. I've read too many dark-oriented stories and I don't really like the protagonist's character or methods. Of course, everyone has their own preferences, right? What I dislike the most is that the protagonist almost got himself involved in the death of the original owner's mother.

The title of the book is not good, but the plot is exciting and the author is great, please work hard!

Not good enough to look at

Very beautiful, super exciting
