An Yang's method for testing the distance between worlds was based on a very simple principle. It was quite similar to the formula for calculating the relative time ratio between two worlds—in fact, it was probably just a transformation of that formula.
Many Spatial Studies scholars in the Land of Origin believed that the distance between worlds was related to the time of the two worlds. The so-called calculation of the time ratio was actually a test of distance. The system had clearly denied that this meaningless "distance" affected the time ratio between worlds, instead proposing a theory of "spatial correlation," which was roughly equivalent to "distance."
In other words, the system's civilization had studied this matter more thoroughly, and its knowledge was more detailed. By comparison, the Spatial Studies theories of the Land of Origin were somewhat crude and contained certain errors.
Ten minutes later, An Yang asked, "System, is the spatial correlation between the two worlds still continuing to increase?"
"Yes!"
"Gasp!"
An Yang sucked in a cold breath. Only then did he ask solemnly, "What consequences will that cause?"
He immediately thought of the fusion and collision caused by the worlds drawing closer together, followed by drastic changes in the worlds—even scenes like the end of the world.
As if sensing his concern, the system's tone remained cold. "It isn't serious. Chosen One, you need not worry."
"What do you mean?"
"There is an attractive force and a repulsive force between worlds. Under normal circumstances, the balance between the two determines the strength of their spatial correlation. The spatial correlation has increased because the attractive force between the two worlds has grown, but they will not draw endlessly closer. Once the attractive and repulsive forces reach equilibrium again, the spatial correlation will remain unchanged."
"Oh..." An Yang
