Ahh yes, safety boxes. I haven't unlocked the recipe in the museum yet, but I've been making some strides to get some. Now that I dumped most of my materials into the factory drop-off slot, it's probably time to start getting rid of all these wooden boxes or changing them into safety boxes (soon). Gonna need to do a few deep dives to get up to thirty relics, I guess. I do like workbench reduction bonus, although I think you need to make batches of five or something to avoid wasting resources (?).
Take me down from the ridge where the summer ends
And watch the city spread out just like a jet's flame
