Rule Invasion: My System and I Travel the World

Introduction: (I can't guarantee that the novel will be unhappy, there will be no Madonna, no heroine, no harem, novice writing, don't criticize if you don't like it) One night, a blood moon hung in the sky, emitting a strange light. Heavy fog is everywhere, and invisible barriers cover every corner. Strange invasion, countless people were slaughtered in the dangerous dungeon. A young man named Report accidentally awakened a master system and embarked on a funny and dangerous road to salvation. "Master System, do you think this world will still be normal..." "Do you think the world is normal? All we can do now is to make the world return to normal as much as possible." "Then can our road really work?" "If it's just you, it's really impossible, but there's me. I'll definitely take you flying, just watch it." Cut off all the weirdness in the world and rebuild a peaceful and prosperous age! (The new author practices on the nth chapter and receives education and criticism, but he may not necessarily change, hahaha.)
