Just like any other good person with a sense of foresight, Rino decided to redeem his limited daily reward and save the remaining nine GF credits he had for other things.
He absolutely refused to buy that day off reward because it was such a rip-off.
There were a few more things he would like to accomplish at the edge of his kingdom before he moved to fulfil a more complicated role.
Despite implementing so many new things on this farm, Rino knew that this was far from his ideal kingdom. It had to be fully automated in all ways possible so that when he took the crown officially, the kingdom would run by itself. He did not really need a luxurious castle or fawning subjects. All he wanted was peace and quiet to do what he loved and be who he was without those false pretences that made him sick in his previous life.
