As a Passerby, I Entered the Weird World of Reasoning Games

If the world is a novel, then I am just an NPC passerby. I have no money, no power, no looks, and no figure. The only thing I can do to help is that I have been particularly popular with some girls since I was a child. The only thing that is different from other passerby NPCs is that I am even more miserable than them. This has to talk about the pain of my original family! And when all the mystery novels in the world became my real life, all the tricks that emerged before my eyes became my step-by-step ladder to become the world's top mystery master. All the events around me are pushing me to go down this path. Sign the World Conspiracy Reasoning Contract with the reasoning system with 100% confidence.
