Traveling to Another World but Not Knowing Magic

A somewhat clichéd cross-traveling work, but unlike Long Aotian, the protagonist in other cross-traveling stories, the protagonist in this article is not Long Aotian, and he cannot use magic like other people in the different world. Not only that, although the protagonist travels as a brave man, many people try to kill the brave man... So how can the protagonist without magic survive in this dangerous different world? This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
