The novel I recommend to you is "Reborn into a Paranoid Big Boss's Favorite." This modern romance novel is a little different from the plot you provided, but the main character is indeed the reborn Qin Feng. This Qin Feng was the second young master of a rich family. He was not favored by others, but he became powerful after his rebirth. I'm not sure if my nephew's name is Jiao Chen, but there are characters like Qin Zheng in the novel. I hope you like my recommendation. Muah ~
