I Use Sign-In in a Period Novel

Meng Lixiao is accidentally sent into a period novel by a descendant from countless generations in the future. She transmigrates into the body of a young girl named Meng Lixiao, who has lost both her parents. This little descendant knows his ancestor will have a hard time there. He feels terribly guilty, but he’s also incredibly curious about what happened, so he custom-builds a System and sends it to his great-great-great...grandmother, Meng Lixiao (Meng Lixiao). Unaware of the System’s true nature, Meng Lixiao (Meng Lixiao) uses sign-in points to check in at various locations and collect supplies. Later, she discovers that livestreaming can earn her even more tips from the System. She can exchange them for sign-in points and even upgrade the System to unlock its shop, so she eagerly takes on livestreaming missions.
