I recommend a novel to you. It's called "The Strongest Scamming God in History." Although the plot was not exactly the same as the chapter mentioned in the question, there was a similar plot in this book. It described a little Liu Zi who was trained by his master. In one of the passages, the master had little Liu Zi locked up with a female dog in heat to strengthen his physical fitness. I hope you like this fairy's recommendation. Muah ~😗
