Started as a Cat, but Crawled Out of Hell

There is a saying in the Book of Rites and Sacrifice: All living beings must die, and those who die must return to their homeland. This is called a ghost. The word "ghost" should be an overall pictogram, and its object is something that humans cannot see. The sage knew the emotions of ghosts and gods, so he created this shape. Ordinary people cannot see ghosts with the naked eye, but they are often afraid of ghosts and gods harming themselves, so they comfort themselves with hallucinations. Ghosts and gods exist in the marketplace, and powerful ghosts have supernatural powers that can hurt people, but people in this world have no means to counteract ghosts. Nowadays, the fate of ghosts has changed. Evil ghosts and fierce ghosts are eyeing humans. Liu Nianqing climbed out of hell, using human nature as a sword, and vowed to protect the vast world of humanity with the green blade in his hand. This novel and its characters are purely fictitious.
