Thunder Valley is a mountain range in the far north of the Xin Kingdom.
Even on Golden Ferghana Horses, covering the whole route would take at least two days.
Ye Tian Yun and his party moved without any hiccups on the first day and night, and soon they had already traversed more than half of the path.
They were already deep into the Northern Province and were about to resume their journey after resting for a few hours in a Tavern.
Even though they weren't tired, the horses also needed to rest. Thus, while the horses recuperated, the group had taken a room and went to rest as well.
Another thing to note was that the place belonged to Gao Suyin, which made everything else very convenient.
Now that they were ready to resume their journey, all of them got on the horses.
Just then, Ye Tian Yun gestured to them to stop.
