Taming the Beast: Starting as the Hero of the Novel and Becoming His Brother

Originally I was just climbing Mount Taishan with my girlfriend, but unexpectedly I lost my footing and fell. When I woke up, I traveled back to my own novel and became the brother of the male protagonist... When other people travel through time, they upgrade quickly, become domineering, have all kinds of golden fingers, and all kinds of beauties pounce on them desperately. Fu Zhengyang, however, had to be careful and careful every step of the way. What on earth is this? This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
