May 18, a Saturday, noon.
When Bai Shi and Nick Horton embarked on their journey,
Chen Yun had already returned home in Runzhou City, Jiangnan Province, from the Rocky Mountains before lunchtime.
The distance from the Rocky Mountains to Runzhou City is roughly around 10,000 kilometers, but for Chen Yun, it was less than an hour's journey.
After all, for someone who could easily reach ten times the speed of sound within the Earth's atmosphere, such a distance really wasn't much.
For Chen Yun, traversing from the North Sea to the Cangwu Mountains in a day, as imagined by ancient people, was no difficult feat.
His superhuman speed made the ancient ideal of "Traveling from the North Sea to the Cangwu Mountains" in a day a reality.
The ancients fantasized about roaming the vast North Sea within a single day and arriving at the remote Cangwu in the south by evening.
The North Sea symbolizes the northern lands of extreme cold; Cangwu points to the southern frontier.
