World view - The Sundered Realm: In ancient times, the world was not a complete continent, but a group of suspended land masses supported and anchored by seven huge creations called "wonders". They are the "stones" of the world, maintaining the stability of the laws. After a disaster called "Nirvana", the power of wonders declined, the connections between the various continents became fragile, the laws began to become disordered, and countless bizarre "exotic beasts" (i. E., The strange beasts and plants in "The Classic of Mountains and Seas") were born or poured in from the cracks in the laws.
The Seven Wonders: They are not simple buildings, but demigod creations with some "living" characteristics, each with its own unique ecosystem and realm of laws. Nowadays, they are gradually becoming "diseased" or "sleeping", causing the world to accelerate toward collapse.
