"From Tianshan to Heavenly Palace City is 360 li, and the same distance from Heavenly Palace City to Tianshan."
Qun Fei faced the wind blowing against his face and said loudly, "But do you know why it takes only a day to come to Heavenly Palace City, but a night longer to go to Tianshan?"
Lu Yuque's voice came from inside the carriage: "Why?"
Qun Fei laughed, pointing with his whip, "Because the westerly wind is so strong, we have the wind behind us when coming here and against us when going back. And we rode horses yesterday, but today we're driving a carriage."
It's unclear what was so amusing, but anyway, Lu Yuque laughed like tinkling silver bells inside the carriage.
Indeed, unlike the May in the Central Plains, under Tianshan, even in spring and summer, the wind direction remains consistently northwest, sweeping over the vast wilderness, howling, as if there's no end.
