On their way down, they found a couple more chunks. Some of these were so hard that Kyle needed hours to deal with them.
Of course, they could've just gone around them, but Kyle was interested in these kinds of materials.
At some point in the future, he also wanted to learn the Level Three Law of Metal, and these chunks would help him.
Additionally, metals were always useful.
They made weapons, machines, and buildings. On top of that, they could be used to comprehend the Law of Metal and could even be turned into Neutral Energy.
When Kyle reached a depth of 70 kilometers, he expected a stream of Yin-Wind, but there was no stream.
The stream of Yin-Wind in the Tertiary World was there to isolate the World Wall and to create more Yin-Elements.
The planets in the Supreme World didn't all have Yin-Wind.
There were other ways to create the Yin-Elements.
These planets were actual planets.
