After the "Human Champion" fleet was established on the bridge, the fleet immediately began relocating the population.
A large number of Bottom Nest survivors were transferred to the Dictator warship.
During this period, Li Changhe also learned about the general defensive structures of the giant cities from the Great Wall.
Within dozens of kilometers around the perimeter of each giant city, there were sentry posts of the giant city.
Then there was the hundred-meter-tall steel Great Wall, covered with various powerful weaponry.
Within the high walls were various residential buildings, all equipped with dense and cumbersome anti-aircraft firepower.
Each giant city, considering future population density and bombing precautions, had set up a Bottom Nest in the early stages of construction below the giant city. The space in the Bottom Nest was vast, akin to an underground pipeline city.
