I think it's possible that Gensou-earth is at a slightly higher density than wild-earth (our planet), meaning we will have to lower the frequency somewhat to fully interact with it. This will make it more like other galactic civilizations and not as isolated as our earth, but at the cost of making alien invasions easier.

I had some things happen in the past week, where after doing some focused cleansings, the energy in my body refilled with "nectar" instead of just qi for the cleared areas. Nectar here means the white/green/yellow energy which is so concentrated it will dissolve normal substances. When the planet opens for real and the new history starts, everyone is supposed to be filled with nectar and live off that for the first period, during which a sustainable society is gradually built up and new crafts are learned.

So everyone is clear on that; societal collapse of some kind will most likely mean there is no production, no functional technology and consequently no food either. But that won't be a problem because of the nectar. As the nectar is used up over time, it will be exchanged for learning methods of survival.
