These rats were called sharp-fanged rats. They weren't very powerful demon beasts, and they weren't very courageous. But this time, they didn't know why they had followed them and attacked their convoy. There were hundreds of sharp-fanged rats in total, but they were easily killed by Zhao Hai and his team. This gave them some extra skin, fangs, and whiskers.
Things like rat skin, rat teeth, and rat whiskers, although they looked very inconspicuous, were very useful. Not only could rat skin be made into clothes, but it also had a certain resistance to earth-type spells. It was also one of the main materials for making earth-type beast soul charms. As for rat whiskers, they were an important material for making talismans. As for rat teeth, they could be used as refining materials. They were earth-type refining materials. Therefore, Zhao Hai and his team had gained a lot this time. Moreover, they sold the rat skins, fangs, and sneaks they got to the caravans they were protecting.
