The Purple Crystal could sense energy in a way that was impervious to all obstructions. The Xuanyuan Dune was like a massive treasure trove to Yi Yun.
"These specks of energy points are likely Chaos Ores. However, they are too scattered and weak," Yi Yun muttered to himself.
The Purple Crystal's energy vision allowed him to see everything within hundreds of kilometers easily. He saw hundreds of points of light. It sounded quite a sizable number, but based on his past experience with absorbing Chaos Ores, he knew that each of the hundred points of light only meant dozens of kilograms to around fifty kilograms of crude ores.
Furthermore, many of the ores were buried thousands of feet deep. To excavate them from the Xuanyuan Dune's firm lands would be a tiring task.
This also explained why ore-seekers enjoyed such esteemed positions in the Xuanyuan Dune. Finding Chaos Ores while randomly digging in the Xuanyuan Dune was just too improbable.
