A slightly easier way to do this game's hidden quests

I was trying to do this game's hidden quests, but there were so many ads it felt like it took 2-3 hours. I got 2000 gems for that. Honestly, time quests are more profitable at this point, but if you've finished those, doing hidden quests is the way to go, right? To finish as quickly as possible, you need to watch the minimum number of ads. This game has a system where you decide whether to watch an ad each time you tap. On the right, there's a button that gives rewards like 3x damage, extra coins, or 5 extra trains if you watch an ad. So, wouldn't it be better to watch that ad instead of a regular one? When you stop in front of your house, you collect and sell cans to make money, and most of the time, an ad pops up then. For reference, it shows a 5-second timer before the ad starts. At this point, you can spam the upgrade button, spend all your money, and right before the ad appears, press the ad reward button. This way, you won't see regular ads and progress faster. If that's not the case, you should minimize your taps. Just hold down normally and only tap rapidly when needed.
