Lin Yuan, who works at an ancient book shop in Qingqiu Village, accidentally awakens the broken pages of half a volume of "The Classic of Mountains and Seas" left by his grandfather due to the roar of strange beasts in the middle of the night, and has since embarked on the road to find his relatives and save the world. He rescued the human-minded monkey and triggered the witchcraft induction in his blood. He also met Su Mu, a girl from the Kunlun clan, and learned that the black mist was the unsealed power of the demon god, and that his grandfather's disappearance was closely related to the fragments of the ancient sky-mending stone. From Yunmengze deciphering the illusion of Red Croaker, to Yushan subduing Jingwei, to awakening Bai Ze in the secret realm of Kunlun, and pulling out the demon bone spurs on Lu Wu's body, Lin Yuan gradually awakened the bloodline of the ancient witch Zhu and collected the fragments of the Sky Mending Stone from Kunlun, Dahuang, and East China Sea. Along the way, Zhulong cubs and Jiufeng joined the team one after another. The partners relied on the power of mechanism, the power of strange beasts and the witchcraft to defeat the hunters, tribes and demon guardians controlled by the black mist again and again. Cracks appeared in Danggui Ruins, and Buzhou Mountain was facing collapse. Lin Yuan gathered the protective coalition forces, fused five sky-repairing stones, and used the ultimate witchcraft to seal the devil and protect the world of Shan Hai Jing.
