Bab 859: Chapter 897: Drifting Materials...

“Ocean resources are divided into four main categories: mineral resources, biological resources, chemical resources, and power resources. The first two of these four types are the most commonly used, but the latter two are also necessary to learn. A normal living galaxy’s ocean area is usually very vast, which leads to a very different distribution of resources. Take mineral resources as an example. You would think that this is a low-level magic region that doesn’t have high-level magic ores, but in some corners, due to the unique natural environment, it can form such minerals. And to judge these, you have to learn ocean chemical element recognition. By identifying the distribution of elements in the ocean area, you can judge what might be born in that location.”
