Chapter 571: Underdark Winter (1)

Two silhouettes were quickly heading deeper into a dark cave.

It wasn't the first time for either of them to be entering the Underdark, but compared to Marvin, Jessica was clearly not as familiar with the place.

The terrain of Rocky Mountain and the surrounding areas was very complicated. Not only was it widely varied, but it was also littered with caves. She had frequently gone to the Underdark before to train.

But that was only the upper layer of the Underdark.

She had never been to the true Underdark.

Thus, she invited Marvin to go with her to navigate. Otherwise, with the Fate Sorcerer's proud temper, she definitely wouldn't accept anyone's help.

This was also due to the current situation being too critical.

The three sisters managed to establish a completely new order in Rocky Mountain after triumphing over many great difficulties, but then they suddenly met with such a frightening encirclement.
