July 2nd, early morning.
The dragon carriage from Heaven City to Holy Spring City has been traveling for more than a day.
Of course, rather than calling it a "horse carriage," it's more fitting to call it a "dragon carriage"—Heaven City is already approaching the heart of the Parthian Ancient Country, especially this time without Sherlock accompanying them. Horses, which require large amounts of water, struggle to maintain body temperature in such high temperatures and cannot travel faster than camels.
As they delve deeper into the Parthian Ancient Country, the daytime sandstorms have become increasingly violent.
Sandstorms on many routes have reached the point of blotting out the sky. Once caught in one, it's easy to lose one's way.
When time isn't pressing, the carriage can hide in a barrier and wait for the dust to pass by... But now time is tight. If they rashly travel through a sandstorm, the horses' eyes and tracheas will be injured by the rapidly flying sand.
