Hill's absence didn't have much effect on the Undead.
In their eyes, Hill was just someone who opened the way. Once the path was cleared, he basically vanished without a trace.
As for having any other dealings with him, either there had to be some major world plot that required Hill to personally step up and take on a big boss, or some Undead had a personal friendship with Hill and visited his home while asking to buy a few good things.
As for the shop, what room for development did Hill have in a low-level world like Oaisis?
Even making jewelry or carving a design would push him past the limits.
On the other hand, the Undead could have a great time here... Hill's method of making monitors was somewhat similar to the legendary methods used to make antique electrical appliances~
Some of the Undead quickly realized that perhaps they could use old-fashioned items from the technology museum and make them with Energy Crystals, which could be polished into energy sources of various sizes.
They hadn't never thought about playing around with this before, but... how should they put it? Their energy sources couldn't be lowered to such a low level. Many of them had wondered why ancient people didn't get burned away by the energy when using such fragile tools.
There was nothing they could do about it. Even the lowest-level planets that could come into contact with the Interstellar Alliance had energy sources exceeding a certain level.
They did know about coal mines and oil, those legendary low-grade energy sources, but ordinary people like them, who weren't specialized in ancient history, really found it difficult to imagine just how low-grade they were.
This was great~ The energy sources of Oaisis seemed to lean toward that era~
