Surface World (Modern): Blue Star has entered the era of "cataclysm", with frequent natural disasters, cracks in the alien world opening, and various alien races (such as Abyss Demons, Nordic Frost Giants, Western Vampire Werewolves, Japanese Yamata Snake Descendants, etc.) Invading Blue Star.
Deep law (mythological fault): After the "Jedi Tiantong" incident thousands of years ago, a fault occurred unexpectedly in Chinese mythology. Heaven is closed, the gods are silent, and the spiritual energy is exhausted. As a result, China could only rely on warriors and hot weapons when resisting foreign enemies. Facing the alien races protected by gods, it was retreating steadily. The national fortune dropped to freezing point, and was ridiculed by countries around the world as a "godless land."
Special space (the world of mountains and seas): a broken secret realm attached to China, where the strange beasts and gods from the "Book of Mountains and Seas" sleep or are sealed. The protagonist's ability is to open the channel between reality and the world of mountains and seas.
