Biologist Nan Qinghuan traveled wonderfully through ancient times, and was snatched back to the cave by the savages at the beginning to eat and wipe clean, facing the unreasonable savage's domineering thinking, "If you want to run, break your legs." Nan Qinghuan said that she just wanted to go home to find her mother, but she didn't expect to live a life of all kinds of pets of savages, some people bullied her, let poisonous snakes bite to death, and some people made her sad and threw them to the orcs to make a good meal. In ancient times, life was hard? Lack of food and less living in a single skin wrap? No, no, there is space in the world. Clay is used for pottery, brine is boiled for salt, silkworms are raised, jackals are trained, tigers and leopards are trained, and bazaars are opened for trade, and a great civilization has been achieved.
