550, the base camp is established!

The alien team of five was now standing in the Second Heaven, which had been chosen as their research and development base and testing ground. Tifa was quite satisfied with the place. Given her stringent demands on the location, after inspecting the relative containment and energy throughput, she gave it a very high evaluation.

"The oxygen here isn't renewable. Before, the reason this place was filled with oxygen was because, although there were no fish or similar creatures, there were plenty of algae and microorganisms in the ocean. Now that the ocean has disappeared, the oxygen level here will gradually decrease. It's just that because the space is so vast, we haven't felt any specific changes yet." Tifa, with arms crossed, circled an area on the map she had drawn: "So we need the presence of natural oxygen-producing organisms. Therefore, I need a lake with an area of approximately 40 kilometers by 40 kilometers in the central region."
