Four teenagers who left the school and entered the arena for the first time went through all kinds of difficulties and dangers in order to find the truth, unravel the mystery of their life experiences, and become a gentleman. They value the way of a gentleman, and demonstrate the chivalry of “using their own strength to make the world fair”. A strange book, a grudge, a belief, a legend. *** _Su Baiyi can rival Zoro when comes to follow directions, he can get lost using a map._ *** **This donghua is adapted from a novel written by Zhou Mu Nan, the author of the Great Journey of Teenagers (Shaonian Ge Xing). The story of Jun You Yun follows a similar route through its youthful journey and adventure. It also shares a lot of similar vibes to established wuxia or martial arts donghua**
