I Will Deal with the Aftermath of the Protagonist in the Heavens

There is a protagonist in every world in the world, but unfortunately not every protagonist can survive to the finale. Some people died in the Novice Village, some were taken away by the system, some failed to be reborn, and some played the world to the end. Lu Chen's job is to enter these unfinished worlds and deal with the aftermath of failed protagonists. He takes the opportunities that the protagonist doesn't get; he avenges the revenge that the protagonist doesn't get; he clears the accounts that the protagonist doesn't clear; he ends the world that the protagonist has collapsed. Until one day, he discovered that behind all the protagonists' failures, there was the same shadow. The protagonist can die, but the account cannot be ruined. If it's bad, I'll end it.
