Under the Rules, Above the Legend

(No system + full intelligence) Besieged on all sides, at the end of the war, everything is not worth it I was a responsible person, but she disappeared in front of me. I am a kind of bad luck, they will all die in front of me... I am a "manager", controlling strange stories, controlling human nature, and using rules. I pave the way for everything, but in the end it is a drop in the bucket! That day, people lost to the unknown... (Note: Because the title of the book is so popular, you can read it as "Under the Rules". Now the title just has a suffix.)
