In 2017, the Fourth World War broke out. The robot army rebelled and used nuclear weapons to destroy the natural environment on earth that humans rely on for survival. The vast majority of humans died in this war with great disparity in power. The remaining humans safely transferred most of their underage children to Mars and other planets, relying on advanced equipment to preserve their slim chance of survival.
Yiyin, a 14-year-old girl from Mars, often looks at the beautiful planet Earth using a telescope at the speed of light. She longs to return to Earth. The average physical strength and intelligence of human beings have lagged far behind the robots invented by humans. How can we defeat the robots and regain our own territory? Carrying the relics left to her by her parents who died in the war, the source of Chinese civilization, "River Map" and "Luo Shu", she embarked on a journey to the earth, starting her journey as a leader to practice immortality, fight wits with robots, go through difficulties, and finally regain dominance.
