In 2300 A.D., after 20 years of interstellar war, the Earth Federation finally surrendered in defeat, and the Earth became an alien colony, and all human beings were the slaves of their country. …… The most prosperous area in the city of Huahai was the rented territory of the alien colonisers, where there was always a great deal of singing and dancing as if it were a paradise, and countless traitors were there to grovelling and begging for pleasure.
