The universe is not a single "dark forest", but a dynamic balance of "symbiosis zones" and "predation zones" coexisting. Symbiosis Zone: A gathering area for low-dimensional civilizations (such as humans), which follows "Signal Silence + Resource Sharing" and avoids meaningless conflicts through the "Stardust Convention". The core is "civilization survival takes precedence over expansion." Plunder area: The activity area of ​​high-dimensional civilization (dimensional controllers, law rewriters), the rules are defined by "strong civilization", which can devour the energy of low-dimensional civilization or transform its survival dimension (such as compressing a three-dimensional civilization into two dimensions).

In 2089 AD, a "dimensional rift" appeared in the human world, space stability continued to collapse, and the earth would be reduced to fragments within a hundred years. The unknown "Dimensional Administration" selects humans aged 18-45 from around the world as "trials", puts them into "trial fields" with different civilizations and different rules, and requires them to complete survival tasks in order to obtain "source energy". The source energy can repair the cracks in the earth and also strengthen the tester himself. However, the failed tester will be directly swallowed by the cracks without any possibility of resurrection.
