Trick to getting this much already: 3 nests, 7 farms, 2 players.
If you ever have 250 gold, buy a second nest (and a third, if you have 500 gold) and always leave them filled with the longest dragons possible, so when an event starts, you can lift them from the nest and collect parts. During the event, buy Water, Air, Light and/or Olympus Dragons for coins to keep your nests occupied 24/7. 2 or 3 nests make world events much more easier.
If you think there can be a world event coming, prepare by making 20-hour crops the day before an update. This gives you a great head-start.
