I recommend "Crossing Ancient Times: Struggling in the Pastoral Land" to you. This novel is about a modern white-collar woman who traveled to 10,000 years ago and lived in a cave with the ancient people. The female protagonist's name was Xia Qingtong. She worked hard every day for daily necessities. In the face of the unusually cold winter in the primitive society, hunger and cold, and all kinds of disputes and infighting, she took her primitive husband and the few buns they made to live together. I hope you like this fairy's recommendation. Muah ~😗
