Chen Zimo, an ordinary college student, awakened a rare "spiritual contract body" on a rainy night when he was about to die on a rainy night, and formed a protective contract with the injured ancient mythical beast Suanni. From then on, he was involved in a mysterious world hidden behind the modern city-the world of mountains and seas.
There are thousands of strange beasts recorded in "The Classic of Mountains and Seas", there are dark organizations trying to rule the two worlds, and there are also the Justice League that protects peace. Chen Zimo has more and more contracted spiritual pets: Jade Rabbit, Chilong, Luanniao, Qilin, Bai Ze... Each of the divine beasts has established a life-and-death bond with him that transcends the contract.
However, the real crisis has just begun. The conspiracy of Emperor Jun, the master of the mountain and sea world, has emerged, and the fate of the two worlds is at stake. Chen Zimo must make a choice: become the supreme master of the mountains and seas, or stick to his heart and be an ordinary person?
The butterfly effect is quietly unfolding - every choice of an ordinary boy is changing the fate of the entire world.
