Geologist Yun Zhi transmigrated to a primitive Beast World and was forced to bind herself to a “Childbearing System.” She soon discovered that each child carried knowledge from a lost civilization, medicine, architecture, law, and more, and was key to changing the world. As she established a city-state with four powerful beast husbands and drove civilization forward, she learned to her shock that the System's ultimate mission was for her to sacrifice herself and become the world's laws. Yun Zhi refused to become a sacrificial offering. She decided to join forces with her family and use knowledge and love to forge a way to survive, both for this world and for herself.
