Yuan Ming gazed at the increasingly distant figures of Yan Xiang and Lei He, took a deep breath, and took out two high-grade Wood Attribute Spirit Stones to replenish his Mana as he continued forward.
After about an hour, Yan Xiang and Lei He had flown far ahead, visible only as two indistinct black dots.
The prohibitive barrier above the lake did not affect Divine Sense, so though Yuan Ming was slower in tunneling speed compared to Yan Xiang and Lei He, he was still clear about the situation ahead.
In the past hour, two Dragon Tooth Crystals appeared ahead, with Yan Xiang and Lei He each snatching one. No more appeared afterwards.
Yuan Ming felt unwilling in his heart, but he kept pushing his Mana forward without stopping; the replenishment from the Spirit Stones was simply not fast enough. He was now showing signs of weariness, and the distance to Yan Xiang and Lei He was growing larger, let alone vying for Dragon Tooth Crystals.
