It was probably because of the preconceived notions brought about by Kukulcan's information that, upon entering this world, Feng Xue had instinctively treated it as a classic rules Kaidan and naively thought, "As long as I survive until the end, that's a good outcome."
But after sorting out the four major systems of this train Kaidan, Feng Xue suddenly realized that perhaps this Kaidan didn't even have an "end" to speak of.
The so-called seven-day and seven-night journey could very well be a false proposition.
Take, for example, the Egyptian Ten Plagues, if the Ten Plagues were a Kaidan, with one disaster each day and the need to survive ten days and nights, would it be enough to simply live through the ten days?
Of course not!
