The tasker travels through the book, and the task is to prevent the world-destroying villain from turning black. She chose to intervene in the villain's childhood, cooking for him, sending him to school, and fighting with him. She thought she was just doing a mission, but she became the only light in the paranoid villain's life. Many years later, the boy pushed her against the wall, his eyes red: "Sister, I'm tired of saving the world. Can you please save me?"

In 2149, humans will establish a third colony on Mars. All immigrants will need to undergo "memory cleaning" - deleting memories related to the Earth to avoid "homesickness affecting colonial efficiency." But the protagonist discovers that his 6-year-old daughter has never been to the earth, but she can accurately say "the old locust tree at grandma's house on the earth" and "the taste of watermelon in summer", and can even draw the outlines of cities on the earth. What's even more terrifying is that more and more children in the colonial area are beginning to "inherit the memories of their ancestors", and the colonial government's "memory cleaning department" is secretly arresting these children on the grounds that "memory pollution will trigger the collapse of the Martian ecosystem." The protagonist gradually discovers that the so-called "memory pollution" is a lie. What the colonial government is really afraid of is that the "truth" about the destruction of earth's civilization is hidden in the memories of these children.
