Which main characters in urban novels had amazing backgrounds from the beginning?

I recommend "I Have Countless God-level Backgrounds" and "Activating the Backgrounds System at the Beginning" to you. They are both novels about urban abilities, and they both have a plot where the protagonist has a background from the beginning. The protagonist of "I Have Countless God-Level Backgrounds" could change the world's laws through the activation system, creating all kinds of mysterious backgrounds and reaching the peak of the world. After the protagonist of "Activating the Backgrounds System at the Beginning" activated the Backgrounds System, he discovered that he actually had such a terrifying background. I hope you like this fairy's recommendation. Muah ~😗
