Time Travel: I Became the System!

Good news, after traveling through time, there is still a system! Bad news, I am the system! He also tied up a second-rate host who called himself Long Aotian! The copies are all from movie worlds that I have watched in my previous life - the plot is all familiar and I can complete it with my eyes closed! Are all host skills bugs? Fireball throwing ham? It's okay, I have bug optimization rights, and I can smash hundreds of ham sausages! Until the copy began to mutate, even my omniscient system began to panic.
