Xu Yan shifted his gaze away from the four enormous stone pillars and began surveying the great hall with a solemn expression.
No matter how he looked at it, this massive stone hall seemed to be an extremely important place to the Giant Spirit Race. He wanted to see whether they had left any legacy behind.
According to Kong Xuan's memories, the Giant Spirit Race had also been incomparably powerful. Their divine sense far surpassed that of cultivators at the same level, and they had even developed secret techniques for using divine sense against their enemies.

The damaged ancient formation was still operating slowly. At each of its four corners stood an enormous dark red stone coffer, roughly six feet wide and ten feet long.
