Tragedy Caused by a Corn Sausage

I'm dead. Because of a corn sausage. After struggling for half my life, I was finally able to reincarnate. I was extremely excited. But the underworld said that I did not die from corn sausage, and I was not allowed to enter reincarnation until the real cause of my death was found. How is that possible! I don't know how I died! In desperation, I could only travel back and forth between the human world and the underworld in the form of a ghost, but the truth about me became increasingly confusing. Beneath a corn sausage lies all the filth and chaos in the world. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
