I recommend a fantasy novel from around 2006. The main character is a man who participated in a tribal competition. In the process of hunting magical beasts, he obtained a grinding core and finally entered the magical beast forest to defeat a very powerful magical beast.

It was an earlier one. The pig's trotters seemed to have changed a little at the beginning. It was not a time-travel novel, but a western fantasy.
