It will be a useful use of dna eventually....I assume...i think that research has to be done anyway before the next big research anyway so its not a waste. The massive gaps between updates are handy when you’ve no quests left as you can upgrade everything and just collect collect. Ive over 30 million dna now due to the wait

Waiting for a future update. Ive nothing to do except collect resources and upgrade everything I can.

I’m trying to remember the way it’s done! Someone else told me. But I think after you surround the oasis with small farms, you put an extra row on the top left and top right then start to upgrade them all. They overlap but are still next to the oasis

The obelisks reduce the time it takes for the houses to be full. It takes a lot of them but makes resources a lot faster

Yup afraid so! All I can tell you is the way I get loads of xenon. I have loads of temples to make sure there’s enough pd to collect as it takes 100 per xenon. Make loads of friends on facebook that play, you can still make your page private from them in settings, and visit them often to place the crop circles. You’ll get to know which players play often so you can collect the xenon more often. Also I have 130 mega farms. They are bunched together real tight. Anyone who visits mine place circles on all my farms. I check back often and collect...9 times out of 10 they are fully loaded again after a little while.
Depending on how far you are in the game the glyphs are handy. I’m hanging around just waiting for something to do as completed everything else so I’m using glyphs to just collect resources and build mega temples to keep the pd up.
Collecting resources is so frustratingly slow!

This is how I get a lot of dna...large houses ready after a couple minutes and mega houses after about 10
