This work tells the survival story of a pair of sisters who faced the end of the rainstorm after obtaining a special system. The elder sister chose to shrink the system, while the younger sister has an enlarging system. The elder sister relied on wisdom and hard work to build a safe mini-farm for herself. She was self-sufficient and lived a peaceful life in disasters. The story conveys the positive belief of independence, self-reliance, and calm response to difficulties, and shows the possibility of individuals relying on their own strength to find hope in adversity.
