The ghost was a fat fellow. After being bumped into by Wang Yao, it was about to curse him, but it was suddenly burned by Wang Yao's immortal body and immediately changed its words. However, it still didn't let it off the hook and didn't become afraid at all after knowing that Wang Yao was an immortal.
"I'm sorry, I'm sorry! This immortal is probably visiting our Underworld for the first time and doesn't know the rules. Everyone is busy, so please don't take it to heart." Ma Fan hurriedly stepped forward to smooth things over.
"What bad luck today, I actually bumped into a fairy while riding a shuttle..." The fat ghost was still muttering to himself.
The train carriage had already started moving, and it felt like it was speeding by. The scenery outside was completely obscured, and the lights in the building formed a continuous band of light as it rushed past.
"Is this... the subway?" Wang Yao asked Ma Fan.
“Our underworld belongs to the lower realm. You could call it a subway, but we call it a shuttle. There aren’t many modes of transportation in the building. Regular subways are too slow and a waste of time. Our shuttle is much faster, at 1,500 kilometers per hour, which is just enough to keep things running smoothly.”
Ma Fan introduced the topic with a hint of impatience.
"How much? 1,500 kilometers per hour is considered fast? Just enough to barely not delay things?" Wang Yao was dumbfounded. In the world he transmigrated to, the fastest high-speed train seemed to be only 500 kilometers per hour. This guy is three times the speed of the high-speed train?
But thinking about it, it makes sense. This is a building, and there are no buses or public transportation. For short distances, skateboarding is fine, since the stairwell is flat and smooth. Once you get the hang of it, it's faster than taking the bus. But it's not suitable for long-distance travel.
For example, it might take a year to get from one side of the building to the other using a skateboard; only this incredibly fast shuttle can do it. And looking at how hurried the ghosts in the underworld are, they probably would find the high-speed rail in the human world, which travels 500 kilometers per hour, too slow.
However, there was still one thing Wang Yao didn't quite understand: how would the shuttle accelerate and decelerate when it was going so fast? What about those locations that were neither too far nor too near, but only short to medium distances? In the human world, high-speed trains could reach their destinations before they even reached full speed. Would the shuttle work the same way?
He muttered to himself, but didn't ask Ma Fan aloud. He guessed that the technology of the underworld and the human world were probably not the same. What a bunch of ghosts did—wouldn't be easily understood by a human, let alone an immortal?
