Earth 2065: the Rise of Double Stars

In 2050, an alien messenger from Centauri A came to Earth with super technology. The messenger used high technology to conquer the President of the Earth Federation, and the two parties signed a strategic cooperation agreement. In exchange, humans allowed the A-Star people to establish a base. However, things quickly turned around. Humanity discovered that in the name of scientific and technological exchanges, the people of Planet A deceived us and took away our resources and scientists, making the earth's science and technology advance by a huge margin in ten years. After that, the Earth Federation declared war on the A-Stars, but was eventually defeated due to the disparity in strength. It was forced to compensate the A-Stars for half of the earth's resources (including labor force) before signing an armistice agreement. The earth has also become a colony of Planet A people in the solar system.
