When she woke up, she fell into the Stone Age where hair and blood were eaten, and she became a weak commoner abandoned in the mountains and forests. There is no golden finger, no superpower, just a bunch of tips for modern life and an optimistic temperament that refuses to admit defeat. Faced with ferocious beasts, barren resources, and strange rules in the tribe, she resolved the crisis with her cleverness - weaving traps with vines to catch hares, polishing labor-saving tools with flints, and even convinced the tribal leader with her clever words to make "eating well and clothed" the tribe's top priority. She does not have a Mary Sue aura, but is only a down-to-earth survivor. However, she has unknowingly made the tribe that was originally struggling to survive gradually become rich, and has also made the cold-hearted leader, the honest hunter, and the arrogant Wu Zhu all become her "loyal fans." This is a funny survival story in ancient times, using wisdom and optimism to counterattack and lead the tribe to the peak of life.
