Sorry, Your Child Is a Snake Baby

During the Republic of China, Fu Zhizhi, the wife of Ning Tao, a rural person, was thirteen months pregnant. This matter became the talk of the town. The snake breeder in the village, Mrs. Hua, saw at a glance that Fu Zhizhi had a nest of snake fetuses in her belly, and told Ning Tao that on the night of the blood moon when the snake fetuses matured, Ning Tao would become the nourishment for the snake babies. However, Ning Tao, who loved Fu Zhizhi deeply, did not want to believe it, and went with Fu Zhizhi to Baiyun Mountain, the snake nest, to find Fu Zhizhi's cousin She Qingcheng for help. She Qingcheng gave Fu Zhizhi a bottle of birth-inducing potion and asked her to drink it on the night of the blood moon to give birth. On the night of the blood moon, Ning Tao witnessed Fu Zhizhi giving birth, and what exactly did she give birth to?
