This Senior Isn't So Cold

Although I don't quite understand what the point below is about being poisonous, as long as the power class in this book is based on identity rather than external force, then everything will be fine. As a god of death, what others hold is not an artifact, just a higher-level weapon. What is the poison?

I am a scumbag with strong combat power, and the protagonist has a magic weapon, and the protagonist has a novice sword. I obviously got it by myself, but I have to come out and take away what the protagonist has worked so hard for. How dare I be in the poisonous spot?
