"Hmm, hmm."
The middle-aged professor nodded and explained, "In the wild, we always need a place to stay, so we all worked together to build some houses."
"The axes should have come from the 'Axe Production Line', right?"
"Without resources, how did you manage to make axes?"
"Without axes, we used stones to slowly grind, cut down trees, and then trim off the branches and leaves, finally building houses. Although it's time-consuming, on this deserted island, the one thing we don't lack is time."
The middle-aged man recalled the past and, looking at Chen Mang, rasped, "To be honest, at first, we thought we all time-traveled together, thinking we were no longer on Water Blue Star. Just before Doomsday, movies had this novel element of time travel."
"Later, after talking to each other, we realized everyone was from Water Blue Star and thought it didn't seem like a collective time travel. What's the situation outside now... Can we still return?"
"Has the government been rebuilt?"
