The Dependable Flying Ship?

The speed of the flying ship was as much as twenty million kilometers per second.

Even then, it took an entire day for Davis's flying ship to arrive at the southern border town. The journey was long and exhausting.

One reason was that, other than simply traveling using the speed of the hull, they had to activate the spatial warp mechanism in the flying ship, which caused fatigue to encumber them as the spatial density affected them when passing from one point in space to another.

Due to this, ninety-nine percent of the people in the Nine-Treasured Immortal Ordeal Palace began to sleep longer hours. In any case, food and energy were provided to them, so they were now enjoying camp life while building makeshift shelters for temporary living.
