Picking up Trash and Raising a Tribe

Ping Shuangyu never thought that one day she would be able to travel through time. What you are traveling through is still a primitive world where food is uncivilized and people eat raw hair and drink blood. The tribesmen who are comparable to Tarzan are so stupid that they don't even know how to resist when they are bullied. Children and old people who struggle with wild beasts and nature every day, but can't get enough to eat. Seeing the honest faces full of sadness, and familiar people leaving due to lack of resources, Ping Shuangyu felt regretful and upset. If she gave them the things she had wasted before, would she be able to save these tribesmen? "Hey! Congratulations to the host for opening the alien resource exchange system. Customer service 001 will be at your service this time." Replacement of resources from another world? Ping Shuangyu was attracted by this word before she could be surprised. When the voice in her head rang again, Ping Shuangyu realized that the alien resource replacement system was a system that allowed her to recycle discarded items in the original world, and then pay a certain amount of compensation to have the system send those items to this original world. Got it, it turns out I just asked her to pick up trash. But looking at the dying and skinny tribesmen, Ping Shuangyu still gritted his teeth and signed the contract. Outdated clothes that don't look good? No, no, no, it can be used to cover the clan members and keep them warm. Unpalatable whole grains and fast food? No, no, no, it can be used to fill the bellies of the tribe and used as seeds. The despised clay pot from the last century? No, no, no, it can be used to cook and pack food for the clan members. Various books that are useless and take up space? No, no, no, that is the cornerstone of the tribe's progress! For the future of the tribe, Ping Shuangyu embarked on the road of picking up garbage and never returned. Motto: Shameful waste! Cherish resources
