Yun Feng nodded. "Ancestor, you mean the energy inside the ores can help humans reach higher levels?"
The ancestor smiled with satisfaction. "That's right. Ores are divided into different levels as well. Low-level ores have the least and the most impure energy, which is difficult to absorb. Mid-level ores are a little better, while the high-level ones are a level higher than the mid-level ones. The ultimate-level ores are the most perfect ones. They have the most and the purest energy that is rare in the world. If you can get an ultimate ore and absorb the energy inside, your strength will be increased by more than one level. If you sell it, you'll get so much money that you won't be able to finish it even after a few lifetimes!"
