Reincarnated as a god of reasoning

"It's turned into a girl."
Ji Yuanqing looked at himself in the mirror.
This is a body as delicate as a doll and as fragile as a doll.
The girl sighed in front of the mirror.
On that pale and beautiful face in the mist and mist, the black eyes were extremely clear.
Even if this look looks a little silly because of confusion and distress, put on her face, it can only make people feel indifferent, alienated and cold.
"But why is this body so weak and sickly?!"
She was a little helpless, this body was too fragile, it was like a glass man, it would shatter when touched.
Money is needed to maintain the body and continue to live. How can an underage sick and beautiful girl make money?
Ji Yuanqing focused on his hobbies in another world, why not write mystery novels!
When the best mystery novels in one world appear in another: Psychological Crime, No Survival, Murder on the Orient Express, White Night Walk, The Devotion of Suspect X, Astrological Killing Magic, etc...
What kind of waves will they create?
Her books contain the most unexpected criminals, the most brilliant tricks, and the most incredible criminal methods. She is... the god of reasoning in this era! "
