I've Survived for Five Hundred Years

My name is Shi Wushu, I am a corpse monster, and I have been lying in this broken coffin for five hundred years. Three hundred years ago, I was so bored that I casually pointed out a female nun who was taking shelter from the rain. Three hundred years later, she became the elder of the largest sect in the world of immortality. She knelt in front of my grave and called "Senior". I thought I could just keep lying down. Until that stupid boy stood in front of me and was slapped away. Until the female cultivator drew her sword and said to the sky full of immortals and Buddhas, "Who dares to touch my master?" I just remembered - I have been living in poverty for five hundred years not just to continue living in poverty. It is to be qualified to stand in front of them when they must stand up. So, I pushed away the rotten coffin board. "Why are you making such a fuss? I've been sleeping for five hundred years and I can't even have a single dream."
