Zhang Yuan looked at his computer screen and a thought struck him—this guy was actually planning the internal structure of the planet fortress!
Even the smallest planet could easily accommodate billions of people. The vast majority of the population would live in underground cities within the Ring World, and the subterranean space within a war star had so much potential for development; it could be stacked layer upon layer like skyscrapers.
Zhang Yuan said with a smile, "This planet of ours, scientists have already planned it out. Housing a billion people would be very comfortable. It's not that it couldn't handle more, but the comfort level would decrease."
"Since we haven't achieved genuine artificial gravity yet, the plan is to build an underground circumglobal track near the equator of the entire planet. The underground city clusters could rotate within the track, effectively simulating gravity. Sounds quite complex, right?"
