"Hmm... a mineral added. Brilliant idea! I'll add that in as soon as I mine the iron needed to make the parts! You are quite a smart girl, Rose. I like that! It's not often that I meet someone of such a high intelligence." Blue said with a smile. Then, he looked around at all the stuff he made. "You know, it's not easy to build all this, even just getting the materials! You see, gold is an important part in my inventions, but gold is very needed around here. The reason why is that there is a dragon currently living on this island, and... well, he demands a set amount of gold every so often, so over half of the stuff I find I have to give to him. But, that does not stop a creative genius like me from creating his works of art. So, what do you want to see next?" Blue asked with a smile.
