System Only Gives Me Useless Gifts

Li Yun grew up with a system that gave him useless gifts. He wanted a reward that could prove the existence of the system, but ended up with abstract gifts like culture. Without physical proof, he was stuck wondering whether his mind was truly sane, all the while dealing with the reality of life and cultivating his own path. How will the "useless" system help Li Yun navigate medical school, hospital politics, criminal cases, treasure hunting, farming, and cooking?
