March 2685, Ceres.
Tiffany Bell finished her day of training and was taking the underwater shuttle through the passage leaving the Summit Research Institute Ceres Branch's No. 3 Mechanician Training Ground, heading to her residence thirty kilometers away.
Ceres, the smallest and only dwarf planet in the Asteroid Belt of the Solar System.
In the Solar System, Ceres has been the focus of attention since the 21st century due to its unique structure.
Its surface contains a large amount of water-bearing minerals, and there is even more ice in its mantle.
As early as the mid-22nd century, humans had already taken root and flourished on Ceres.
After hundreds of years of transformation, the once rock-covered Ceres has long become a verdant paradise.
Under the restraint of the force field shield, Ceres has an almost identical atmospheric layer to Earth.
Humans have implanted a gravity device in the core of the planet, and the simulated gravity environment is exactly 1G.
