There Is Actually a Ghost Realm in My Ghost Sword

My name is Ye Qing and I am an ordinary person but they all call me Yama. I am confused because I am obviously a kind person. … "We just want to live, so what's wrong?" "Haha your existence is a mistake" … Are there no kind ghosts? Do people have to be right and kind? "No... Don't, don't, don't want your parents." "Ah ah ah, I want to kill all the ghosts in this world." "Son! What are you doing? We are not ghosts, we are your family." … "People are selfish and evil monsters. I want to create a world of ghosts and monsters." "Hahaha I want to kill all human beings" … "Ye Qing!"
