Underground
"Do you see that cave over there?" Su Yang suddenly said to Xiao Rong after walking for a couple of days without uttering a single word.
Xiao Rong turned to look at what Su Yang was looking at, and sure enough, there was a cave entrance there.
However, this entrance was barely big enough to fit a single person inside.
"That cave will lead us underground, and once we enter it, we won't be leaving for the next 50,000 miles. It is also the last safe shortcut in the Frozen Asgard. There are still hidden passages after this one, but they won't be as safe, as they are quite spacious so the larger magical beasts sometimes wander in there."
A few minutes later, they arrived before the cave entrance, and Su Yang had to forcefully squeeze himself through the narrow entrance because of his round figure. In fact, he even damaged the entrance a little by doing so.
As for Xiao Rong, her petite frame allowed her to enter with ease.
