As an outstanding employee of the quick transmigration bureau, Song Yuan has always had an excellent track record. The other Systems are all extremely envious of Song Yuan's System, thinking that working with a big shot must be a breeze.
Song Yuan's System: ...It is a breeze, all right. He doesn't even pay attention to me, his System. His approach to completing missions is basically just to rebel.
In a Mary Sue world where the entire school adores the true heiress who transferred in, Song Yuan glanced at his mission and went off to become an entertainer instead. You have four men who like you; I have eight million fans who like me. We both have a bright future. Wait, why did that number suddenly become eight million and one? Tsk, why is the original heroine secretly a fan of mine?
In an interstellar food novel, he refuses to make food and instead takes over a nutrition-fluid company on the verge of bankruptcy, developing all kinds of delicious new flavors that better suit the tastes of interstellar people. The original heroine can't even be bothered to cook anymore and comes straight to him to collaborate.
In a cultivation harem novel starring a domineering hero, he pretends to be the expert inside the jade pendant that is the hero's golden finger, then gives the hero a special cultivation manual that solves his harem problem at its source.
System: The mission in this world is blah blah blah. The recommended approach is blah blah blah...
Song Yuan: What kind of nonsense is that recommended approach? I'm not listening.
System: ...You're so rebellious, big shot.
Song Yuan: Just tell me if the mission is complete or not!
Premise: Your life is in your own hands.
