In the lonely universe, there is a spacecraft named Serial Number floating.
The serial number spacecraft took off from the blue star of the solar system and flew disorderly in the endless universe for a long time until a world called Equation appeared in front of him.
The equation world is a special world with squares as the basic unit. Among all the forms in the equation world, the square is the basis of everything. Special forms can be processed with the help of special tools or carved naturally.
For a long time, the world has existed in a square shape. No one knew what existed outside the square world, until a human from the round world appeared, and the door to the end was opened unexpectedly.
