Just Pick Someone Up! Why Did Primitive Society Come?

[Not a world of beasts, no CP, no description of medical skills. The ultimate goal is to go home and develop the tribe by the way. I am a new little girl. There is no way to change the label. If you don't like it, you can exit] Lin Yao was accidentally bound to the plant collection system and was brought to primitive society by the system. Enough plants needed to be collected for the system to accumulate energy to bring Lin Yao back to modern times... But there seems to be something wrong with this mission! I didn't tell her anything other than collecting plants. We still have to fight wild beasts, build infrastructure, and grow food! As I continue to complete tasks, how come my tribe has become a super big tribe that everyone wants to join? I just simply want to go home...
