Drifting Between Worlds Against My Will

A goofy Host paired with a System that can do nothing but transmigrate and teleport sets off on a life of traveling through worlds of cases, murders, and hauntings. Everything will get more and more ridiculous. I won't make the protagonist stronger. I'll just make him stay alive while murderers and ghosts chase him down. The protagonist is only there to bring the story to life. I'm telling stories, not writing a power fantasy where the protagonist can instantly crush everyone. As long as he stays alive and doesn't die, that's enough.
