In the golden age when human civilization expanded to the third galaxy, the seemingly prosperous interstellar republic secretly followed the laws of the dark forest. Iris Tong was originally a low-level gene editor, designing offspring for the powerful. Once, she discovered the original human genetic map in an abandoned gene bank. When she tried to decipher it, the deep space probes in the galaxy were collectively silent, and the genetic recombinants in the cultivation cabin were focused on the coordinates of the earth. In order to maintain the rules, the high-level officials of the Republic regarded her as a threat and tried their best to stop her. Tong Iris knows that failure will lead to the destruction of mankind, but she is only a low-level employee and lacks strength and resources. She was unfamiliar with controlling mechas at the beginning, and struggled to survive in the interstellar war where all forces were fighting. He was also slandered by senior officials and misunderstood by the public. But with the help of her helpers, she gradually mastered the mecha skills. As advanced civilization approaches and time is running out, she must break through class restrictions while resolving misunderstandings and uniting the forces of justice. In the end, he succeeded in preventing the destruction of civilization, but he also bid farewell to the past peace and embarked on a new journey of guardianship.
