In this world, some people practice swordsmanship and some use them. There are also people who are selected by the knife.
The year Gu Wei entered the city, he was eighteen. Nameless and powerless, he only carries a knife. The name of the sword is unknown, but everyone comes to get it. Some people take orders, some keep accounts, and some just watch. As he walked, people died along the way. Along the way, there were people watching. Until later someone asked: "Who is that person?" Someone replied: "Gu Wei." No one said anything more.
