Conan: Start by Killing the Protagonist

Pull the trigger, the firing pin penetrates the primer, and with a bang, the bullet streaks out of the barrel. Shirakawa Shihang looked at Edogawa Conan not far from the gun, and memories of the past played out like a revolving lantern. From the time he entered this body to now, it has been a full year, and he has finally managed to get into the protagonist group. Why has he reached this point? A voice sounded in the chaotic mind: "I have been trapped for a year, it's time for me to come out." (Note 1. The timeline is fine-tuned, cases are added daily, and the plot direction is not the same as the main line. 2. The protagonist appears in the second chapter. He is a native of the Conan world and only knows one or two key time nodes. )
