What is the Unlimited Flow novel genre?

Unlimited flow (also known as Infinite Flow or 无限流) is basically when the main character is pulled into different spaces or another realm. According to ArkMachine, people are summoned to unique spaces separate from the real world and have to complete tasks, generally stuff like puzzles, survival, or horror games.

According to Baidu, the meaning of infinite flow should be “all-encompassing”, that is: it contains infinite elements, including science, religion, mythology, legend, history, reality, movies, animation, games, etc., and higher than them, there is such a world view that includes all of them. Infinite flow novels are generally unique spaces created by technology or supernatural powers unknown in the world, summoning people in the world and sending them to virtual spaces created by this space for experience and so on.
