Origin Gold was the sturdiest thing in the world, and even the Great Emperor couldn't damage it.
Thus, the Origin Gold could only be burned in the strongest flames in the world. After burning to a certain extent, it could be molded into any form.
But it should be known that adamantine and the like had to be hammered over and over again to be able to reach the requirements of hardness and sharpness.
The Origin Gold was naturally different. It itself was the strongest material in the world, so it was definitely pure.
However, no matter how pure it was, there would still be a trace of impurity, which would affect its might.
Now, the Metal of Creation's effect was to expel these impurities. Although it didn't completely transform the Primal Chaos Extreme Lightning Tower, its might definitely increased a bit.
"I have a feeling that as long as I have enough Metal of Creation, I can completely increase the quality of the Primal Chaos Extreme Lightning Tower!"
