Yue Jin first appeared in Chapter 5, in which he joined Cao Cao's forces when the latter was rallying an army to participate in the campaign against Dong Zhuo. In Chapter 11, when Cao Cao was at war with Lü Bu, Yue Jin engaged Lü Bu's general Zang Ba in a duel but neither of them could defeat his opponent after fighting for more than 30 rounds. In Chapter 23, Cao Cao praised four of his generals – Zhang Liao, Xu Chu, Yue Jin and Li Dian – in front of Mi Heng, saying that the four of them "possessed unwavering courage and surpassed Cen Peng (岑彭) and Ma Wu (馬武)."
