Back and forth [Bonus Chapter: PS last week]

"I knew I would soon face the very problems I'm trying to solve in advance… but to think I would reach that stage already…"

It's been an hour since Theo finalized the last build back at his copper place, allowing him to finally move on to the next most important step of his plan.

Yet, contrary to how simple it sounded when thought out, bringing back every last item produced at two of his extraction and processing caves over to his main mining base…

Normally, it wouldn't even be all that hard or annoying, only requiring Theo to steel himself for just long enough to lay down all the necessary conveyor belts.

The problem was, by the time he finally managed to create a new, sizable cave just next to the main one and then route the iron ingots and iron plates there…

He ran out of the conveyor belts.
