The treasure cave hidden inside the small mound of earth was a long, narrow passageway, over thirty feet wide and more than three hundred feet long.
When Ye Chen entered this secret passageway, he found that there were no "Netherworld Ants" moving about at all, he could only see several spheres the size of human heads hanging on the wall at the very end of the passageway, emanating a dark red glow.
Besides those several head-sized spheres with dark red glow, there was an even larger sphere that displayed a mystical golden yellow color!
What surprised Ye Chen even more was that on the walls of this very hidden secret passageway, in addition to the hanging spheres of two colors, there were deep and chaotically scattered battle marks, and on the ground, the desiccated corpses of thousands of Spirit Insects could be seen.
