According to the information provided, I recommend the novel " Almighty Flower Protector " to you. The story tells the story between the male protagonist and the female CEO who went down the mountain to protect her. Although there are no elements of the Twelve Gods or the Ouyang family, the plot is compact. The male protagonist has a strong ability to protect women, which meets your requirements for Apollo and the Ouyang family novels. I hope you like my recommendation.😗
