This is the Commonwealth of America. A multi-colored human race coexists, and technology flourishes, but it is full of all kinds of ugly places of human nature. My name is Brian, and I'm an energetic, two-and-a-half-year autopsy assistant. I live a boring and boring life every day: I check the health of the deceased during the day, check the health of the dreamers who have just arrived in the metropolis at night, and occasionally take care of the work-study federal college students, so as to make a modest contribution to the independence of the new generation. Until the red moon is in the sky. A corpse that had just been sent over grabbed my hand with the knife... Uninteresting life. It became interesting! ... A modern era of science and technology with a little bit of magic background. The core of this book is an interesting case and how to die, and through the vision of the autopsy, I will tell you about the love, hatred, hatred, and resentment that occur in parallel worlds.
