God Catches? No, I'm Just Laying It Out Behind the Scenes

My name is Lin Bai, an ordinary time traveler, until I activated the secret system behind the scenes. This system is a bit weird. It doesn't let me stand out. As long as I hide behind the scenes, I can get rewards easily! Layout option one: Write an anonymous letter to the chief catcher, identifying the real culprit. Reward: Kung Fu Eagle Eye Technique! Layout option two: Testify against the murderer in person. Warning: 99% exposure risk, reward: none! Is this still a choice? Decisively be the sixth child! As a result, the style of painting in the capital's yamen changed: The once stupid young man suddenly seemed to have divine help and solved strange cases one after another! A notoriously reckless man who always hunts down people suddenly gets his IQ online and repeatedly performs extraordinary feats! Each of them was praised as a "magic catcher", promoted to a noble position, and shed tears of gratitude. And I, the most useless "good-for-nothing" in the whole yamen, silently watched my skyrocketing cultivation and reached the pinnacle of martial arts. The introduction is weak, but the main text is even more exciting! Arrange the Oiran case at the beginning and directly reward ten years of cultivation!
