The journey back to the Spiritual World passed through five galaxies, 11 solar systems, and a total of 23 planets.
The first part of the journey was between the Artificial Moon and the galaxy, where the group would be able to travel to the galaxy where The Adamant Land was located.
There was no spaceship that could take them directly to the galaxy where the Mechanic Empire was born, but there was a place that could take magical creatures to the galaxy where the solar system of The Adamant Land was located.
From that place to The Adamant Land, the robot in Minos' group was sure it could lead them to their homeland.
From there, they could return to the Spiritual World through the universal wormhole that this empire had created for Minos and Ruth's home planet.
