The former captain of the Dragon Teeth Team, Zhao Ziyi, encountered an undiscovered virus infection while performing a mission, but it cannot be cured by current medical treatment. She has only three years to live.
After a hundred years, the United Alliance once again proposed a plan to invade the planet Nevi, calling this plan the Tirses Plan. Zhao Ziyi's grandfather, the general in command of the alliance, protested against the plan, but was opposed by most people and was even killed.
In order to show the sincerity of the Zhao family, the alliance allows one member of the family to participate in the first trial. He must not refuse, otherwise the Zhao family will be sentenced to death.
Zhao Ziyi participated in the experiment for the sake of the whole family. The experiment failed, but she did not die. Instead, she arrived on the planet Nevi a hundred years ago, and became a newborn baby. Here, she met her lifelong partner, who was once a human on Earth.
