Dual world system
◦Surface world: The modern city "Linhai City", on the surface it is an ordinary city with advanced technology, but in fact it hides a "hidden world" composed of descendants of the strange beasts and immortal cultivators in "The Classic of Mountains and Seas". City landmarks (such as Linhai Tower, East Lake Ancient Temple) are all ancient seal nodes
◦The inner world: "Nine Domains of Mountains and Seas" corresponds to the secret realms recorded in classics such as "Great Wilderness East Classic" and "Great Wilderness South Classic" in "The Classic of Mountains and Seas". Each realm inhabits unique exotic beasts (such as the Qingqiu Fox Kingdom and the Kunlun Enlightened Beast Territory). The passage between realms needs to be opened through the sealing cracks in the surface world.
