Lin Ye unexpectedly discovered that his ancestor was actually the keeper of the "Book of Mountains and Seas". At first, Lin Ye did not believe that the mythical beasts in the "Book of Mountains and Seas" really existed. He only accepted it after meeting Lin Ze of Donghuang and Qingqiu nine-tailed fox Tu Shanyue. Following the instructions of the fragment of the Book of Mountains and Seas, he went to find the reason for his grandfather's disappearance. He encountered difficulties on the way and walked through Nanze, West Desert and Donghuang. In the final battle of Kunlun, he used the token left by his grandfather and his own protective heart to unite the mythical beasts to calm down the crisis.
