A decade huh, that's really like a time span of long-lived elves.
"By any chance, magic tools can be made by using this money?"
"Yes, originally philosopher's stone should be processed first in order to reinforce its magic power when it's used as catalyst for making magic metals. I'll teach you later if you want to know about it. I don't remember it now, but it should be in the memory deposit of the world tree."
I decided to accept her kind offer. I accompany Aze-san to the world tree, and learn the way to use the Crimson Treasure and to make magic metals. The Aze-san inside the memory deposit is divinely beautiful like a demi-god that Leriril said back then, and she's showing intelligence beyond human understanding. But well, if this was how Aze-san was during our first meeting, I probably would not fall for her even though I surely would think she was beautiful. Aze-san is someone who does "Awawa" after all.
As a compensation, or not, I gave around 1000 Crimson Treasures for the elf hometown since it looked like it would be useful for them. I feel slightly proud since I was able to see the surprised looks on the elders who hardly showed their expressions.
