Chapter 581 The Decline of the Planet

Compared with building an underground fortress, the difficulty of exploring space with sunshine was not much.

"It's unrealistic to raise all the people with such a difficult space."

"Even if we have stored a large amount of nutritious liquid before, we will still have a day without food!"

Su Wang thought that they still needed to return to the ground and face the dark insect race.

But at that time, they didn't have any buildings on the ground that they could borrow.

They had to protect the last core city.

Even if there were only a few remaining cities, they could still make use of them to start a fire.

"It was not easy to argue with each other before. We won't give up easily. Now we just let the public live underground."

"We will have the last defense line according to the fortress on the ground, but this result is not the optimistic one we think."

Leng Feng spoke out about what he was thinking. He thought it was also what Yang Yi was thinking now.
