While I have complete confidence in his abilities, if he misses the Ghost Train five hours from now, our supplies won't last until two months later."
Because of the Earth's rotation, only by traveling from Chunming City to Cairo could they use the time difference to bring the "keys" back to Chunming City on the same day. In reverse, if they traveled from Cairo to Chunming City and wanted to return to Cairo, they could only wait another month.
