Accumulating Gold (Leveling Up) Secret Tips 3

Just like in the previous post, to graduate (?) on time, you need to effectively use the pop-up items and this cash register~ The highest level seems to pop up once every hour. The highest tier item you can combine is toilet paper. Collecting 2 of them will automatically trigger a treasure chest quest that you can complete for the prize shown in the picture. Also, completing quests that appear only after you've collected all the required items counts towards your weekly quest count (if your weekly quests include something like 'complete XXX quests') ← That's a tongue twister, isn't it?
