Both you and Herta were still hard at work making sure the mass production of aluminum goes well. Things got exponentially smoother as Cattleya continued to organize the materials in the storage area, leading to less headaches and more efficiency. It was interesting to consider how small things like that could decrease the workload.

The underground ventilation system setup was going decently well— some Lunacy Savantae and enchantments went a long way to keep the room fresh. Although you were inspired by the magical larder in terms of ensuring a good air circulation and quality, there was an undeniable stuffiness that took hold of the entire room if there wasn't anyone (or any machine) to work the air pumps and bellows. Automation sounded like an easy solution, but it was weirdly difficult to do in this situation. Though that might just be because you and Herta were basically brute forcing Savant-made things to work together. This all was, in many ways, new territory for both your Lunacy Savantae.

One thing was certain, and that was the fact that the two of you working together made things far easier and efficient.

While this was bound to be finished soon and would bring about the steady flow of aluminum bars into your supplies, you considered making a factory above ground instead this time. Herta suggested this offhandedly, mentioning that building it on the surface would get rid of all the needless complications and confusions Lunacy Savantae could bring. This was especially useful if you wanted to expand the factories at a larger rate.

Refining and smelting the materials you had into aluminum would never be efficient underground, though it would help if you wanted to keep things hidden from airships and better protected from potential design thieves. But making an industrial facility or twenty on the surface would also be useful for multiple reasons. Although, with both you and the goddess, it was possible to do both next week at the same time, if you were fine with a less efficient rate of construction. On another note, it might do you and Herta some good to look at some other projects instead for now.

>Make another smelting factory above ground. (Uses up John Doe's and Herta's action next week)
>Continue as you were, expanding underground facilities and experimenting more with Lunacy Savantae. (Uses up John Doe's and Herta's action next week)
>Why not both? It should be manageable if the two of you work on it. (Uses up John Doe's and Herta's action next week)
>Actually the two of you should take a break from this and focus on other matters. (John Doe and Herta will have their weekly choices like normal)
>This wasn't a bad idea, but you felt like it didn't need the two of you to complete. (Who continues the aluminum production? The weekly action will be available for the person not doing it)
>(Write-in)

Ayane said that this underground construction reminded her of a tatara; an underground furnace used to make swords and armor.
