Kyle found a lot of different metals and started to study them.
However, studying them was not very easy.
It wasn't that they were very complex, but that he simply didn't have enough Energy.
Yes, his physical power and Battle-Strength were incredible, but there was not a lot of Energy inside his Center.
Heating the metals was very draining, and it took a long time.
It still worked for the Low Primal Materials, but it wouldn't work for the Medium Primal Materials.
Understanding the Low Primal Materials took a bit more than five years.
Sadly, as expected, understanding the Medium Primal Materials was not easy.
Kyle couldn't experience how they acted under heat, which meant he couldn't look at them in their liquid and gaseous forms.
However, there were also ways around them.
Kyle's Complex Law allowed him to cool the metals significantly.
His Yin-Wind also allowed him to break small parts of it.
