Lu Tianjiao was originally a modern person with terminal cancer, who crossed over into the interstellar beast world and became a vicious female who was misjudged as F-grade and abused her young. Facing Xiong Lili forcing the purchase of children, neighbor discrimination, and family poverty, she decided to protect a few snake cubs and feed them. She collected relief, sold mutated crystal cores, and planted tomatoes, gradually awakening abilities such as healing, purifying crystal cores, and pausing time. Jin San, Jin Si, and Jin Wu went from defense to dependence, and her missing beast husband Jin Ye also affected her destiny through dreams and contract seals. To redeem Jin An and repair the family, she brought the children to move into a new home, but the giant beasts in the lower layers, Jin An's hatred, and Jin Ye's return still made life full of crises.
