Great Kingdom Tiangong: Luan Bird Takes Off into the Sky

In 2068, the two sky orbits will be connected, and humans will send materials into space at a cost of US$13/kg. After 32 years it dropped to $10. The population of the Moon increased from 320 to 2100, and the population of Mars exceeded 1000 from 45. In 2070, a new generation of engineers who inherited the "homework" spirit of Tianji Gate started from AVIC's 2017 pencil sketch and launched a plan to build a 120,000-ton Luanniao space carrier in orbit, carrying 88 Xuannv AI fighters. From IP to engineering, five to six generations of aerospace professionals have gone on for 98 years.
