Throughout that first day he focused on making his electricity automated. With a big wheel and a bowl full of water, that was more or less done, at least to the point where he was happy with it.
Next, he was down to make his first computer system, a simple sort, but he hoped from there that he could make the most basic of AIs and begin to automate the processes.
The only problem was, again, his lack of materials. He had not the quartz sand needed for silicone nor the oil needed for plastic. It took a whole day of waiting before materials of that sort were finally delivered to his door and even then work needed to be done on them.
Throughout the process, Gengyo had to continually remind himself not to attempt to make anything too complicated straight away. In truth, all he was doing at first was making his tools.
