Hidden Quests Full Gotcha (All Completed)

With only 18 days left, I finally completed the last hidden quest, 'Complete Village 80'. And I've completed (almost) all the hidden quests imposed by this game!!!!! I did it. This is actually the first time I've managed to get a full 'gotcha' (all completed) on the hidden quests (excluding paid ones, of course. I generally don't spend money unless absolutely necessary). Even after completing Village 80, I still had energy and coins left, so I thought I'd use them all up while I was at it... but then I consume energy or coins → I get more energy and coins as mission completion rewards. A perpetual motion machine, just like always, was completed. Moreover, coins piled up to nearly hundreds of millions, even trillions, and energy reached five digits... Furthermore, even when consuming event items, I received a ridiculous amount of coins and energy... so I couldn't really use them all up. In the end, I pushed myself to complete up to Village 100 to forcibly finish. It ended up taking nearly an hour, all things considered... Thinking about how much longer it would have taken if I had stubbornly tried to use everything up makes me shudder slightly... Normally, consuming energy finishes in a few minutes, but in a perpetual motion state, it can drain tens of minutes...
