Unexpectedly, he accidentally ran into his girlfriend having an ambiguous relationship with someone else. But his girlfriend Li Youyou not only did not know his fault, but also joined forces with Sha Yilong to beat Lu Hao severely. Lu Hao was injured by a toad in the forest, but he gained medical skills from it, so Lu Hao defeated Sha Yilong.
