200 Years ago, a third-level civilization "Hao" landed on the earth. After friendly communication with the people in power at the time, the earth successfully became its affiliated civilization and promised to provide the earth with a batch of scientific and technological support every two years. The earth has developed rapidly since then.
100 Years later, Earth's scientists discovered that their research results during this 100 years were far less than a small thing casually provided by "Hao", so they all gave up research, and the Earth's own scientific and technological progress gradually disappeared.
Due to the limited resources provided by "Hao", the new group of people in power had a fierce conflict with the old group of people in power. In the end, the victorious side established 10 utopias and 200 gate cities to protect the utopias on the earth.
At this time "Hao" revealed its true face
Beautiful and funny.
