Use the Ke Xue Vest to Do Reasoning in a Different World

Nakamura Nohiro is a social worker who hangs out in 996 every day. One night, he stayed up all night to catch up on a popular broadcast. After death, the soul floats in the three-dimensional space and obtains a reasoning system, which is also a variety of different worlds, and even involves cold stories that he has not seen. The system allows him to return to the world as long as he uses Ke Xue's knowledge of the world and completes the reasoning tasks with the help of various vests. When I heard it was Ke Xue's world view, I refused without even thinking! "The Ke Xue world view you are talking about refers to that famous detective movie where there is no one in the episode? I quit, and I don't know why I will die someday. I think it would be good to be reborn like this." But... The system enforced it and pushed him directly to the scene of the crime, turning him into a certain child, Genta Kojima. Low-level vest—children! Nakamura Nohiro: "..." —— If he could choose his own vest, Nakamura Nohiro wanted to choose Mouri Kogoro because he wanted to win the mission. Instead of accidentally getting the perverted vest of a certain organization later, that is, the ruthless Gin. Can he still reason about things that he can solve with a gun? Demining: The character is OOC, has some personal settings, involves several world views, and keeps the vest intact. Intention: Work hard and never give up
