Dual-layer world system
◦ Surface world: The modern metropolis of Linhai City appears to be an ordinary, technologically advanced city, but it secretly conceals a “Hidden Realm” inhabited by descendants of the mythical beasts from the Classic of Mountains and Seas and cultivators. The city's landmarks, such as Linhai Tower and the ancient Donghu Shrine, are all nodes in ancient seals.
◦ Inner world: The “Nine Domains of Mountains and Seas,” a collection of secret realms corresponding to places recorded in texts such as the “Eastern Classic of the Great Wilderness” and the “Southern Classic of the Great Wilderness.” Each domain is home to its own mythical beasts, such as the Fox Kingdom of Qingqiu and the territory of the Enlightened Beast of Kunlun. Passages between domains can only be opened through cracks in the seals within the surface world.
