A poem says: The immortal path is difficult, as difficult as a mudfish transforming into a golden dragon. The immortal path is lonely; after experiencing countless hardships, looking back, there are no familiar faces left in the world! A mysterious immortal bone allows the young Yang Hao to embark on the long and arduous path to immortality. Even if the path is fraught with difficulties, he vows to cleave mountains and rivers, and ascend to immortality step by step!
