Rika and Hikaru...

"The core of the world?" Hikaru saw the bulletin board and was surprised.

[That's right. Although this is only the most basic state, it is truly the core of the world.]

[In simple terms, it can power things for a million people in the territory to use Runes comfortably for 10,000 years.]

"So… what if it powers home appliances?"

[You mean you want to turn this Core into a giant generator?]

"That's right. I want to reform utilities that support life, but for a better life, electricity is indispensable."

"There is no electricity in this world, so I want to use something else instead. I think the energy within this core can be harnessed."

"Anyway, I still have a lot of soul points and elemental stones right now. Besides, we can also let Anno use the Lucky Dice to get even more resources."

[Hm… according to my calculations, if it's used by 1 million people, it will only last about 500 years if used at full capacity.]
