The Dimensional Journey of the Bad Knight

My name is Lin Lin, and I am a dead person who signed a contract with the knight system because of a wish that I said casually.Of course, I am alive now.
But, is there something wrong with the person who lent me strength?
When the Demon King: You have the potential to become the Demon King.
evolto: Black Hole played well, boy.
Lao Tan: Don't be too arrogant, even if you are promoted to administrator, I am the administrator of life!
……
Fortunately, those are small issues.No matter where the power comes from, I am me and everything is ok.
Overthrow what should be overthrown, protect what should be protected.
Today, I am also passing through other people's worlds.
