In the discrete disk area of the solar system.
The discrete disk was a remote area of the solar system, but it was the area closest to the solar system's high-temperature fire screen. Astronomical observations sometimes took the shape of a semi-elliptic belt, but sometimes it was a regionally concentrated belt.

The reason was that most of the asteroids in the scattered area were composed of ice. Furthermore, the force fields were extremely complicated and mixed. Collisions and fusion were constantly happening.
It was also because of this that the expeditionary army, which was originally scheduled to arrive around 25 days ago, took 27 days.
