The sound of the train wheels rubbing against the rails and the engine rotating every time the train's gears rub against each other. However, there was no sound of smoke coming from the carriage. A train crosses the track very quickly.
This train does not run due to burning coal or electricity. Instead, it uses another power sourced from a unique stone called a mana stone.
Mana stone is a mineral that can be found in the ground. Like other precious minerals, mana stones must go through several purifications before they can be used. However, what comes from this mineral is not how it is purified, but how it is formed.
In contrast to mutated animals and rare plants which can only live and grow in places where mana species do not live, Mana stones are always found in places where mana species live. Especially in places where many mana species died and were buried in it.
That's right.
