The South Pole Island

Unfortunately, they didn't find any more Spiritual Aura-Gathering Stones. Mo Tiange thought for a moment and shook her head with a smile. Spiritual Aura-Gathering Stones weren't rare treasures, but they also weren't particularly common. It already wasn't easy to find one in such a small spirit stone vein, yet she wanted to find more? 

Mo Tiange waved her hand to call Xiaofan back and said, "Let's keep going." 

Xiaofan responded and carried her to continue swimming ahead. 

The spirit stone vein was really small, and only a moment later, Xiaofan had swum out of range of the vein. They then faced the dark underground riverway again. 

Mo Tiange had become accustomed to such darkness, so she simply calmed down and began to comprehend her inner realm silently.
